Position Determination Performance Analysis of P0-P4 Motor System Architecture

  [car home New Energy] In the eyes of enthusiasts and technology controllers, the new energy vehicle is more like a work of art, and every core component is its essence. When talking about pure electric vehicles, they will ask you about battery manufacturers or battery suppliers, which can be regarded as the second brand of vehicles; When it comes to hybrid cars, they will ask you "P". What do these slang words mean? Today, I will talk to you about different types of motor architectures for hybrid vehicles.

  At present, the application modes of motor architecture in the industry are different, and the specific applications and explanations under different architectures are also slightly different. The starting point of this paper is to sort out the basic principles and application modes of p0-p4 architecture and the purpose of different combination schemes.


● Definition and analysis of P0-P4 motor

Home of the car

  In hybrid electric vehicles, it can be divided into P0-P4 and Ps architectures according to the different motor Positions, where P stands for motor position, and the motors in different positions play different roles, which are directly related to vehicle energy consumption and power performance. Which hybrid electric vehicle is more suitable for you?

◆P0 architecture: simple structure and early fame. 

  The motor with P0 structure is installed at the front end of the engine, which is connected with the crankshaft of the engine through a belt. The vehicle equipped with P0 motor can drive the mechanical compressor of the air conditioner to run when the engine stops at the traffic lights, so as to realize engine start and stop, braking energy recovery and power generation, and auxiliary power output.

  The technology and structure of P0 architecture are relatively simple and widely used. The automatic start-stop system that many drivers and friends shut down when they get on the bus is a typical P0 architecture, and the history of automatic start-stop can be traced back to 1970s. Compared with vehicles equipped with automatic start-stop function, P0 architecture adopts BSG (belt-driven starter/generator; Belt-driven starter/generator) motor, and equipped with a larger battery, can be competent to drive the compressor and auxiliary engine.

  When the engine is stopped, P0 motor can drive the air conditioner compressor to work independently, thus reducing the idle time of the engine; When the vehicle starts or accelerates, P0 motor can assist the engine to run, help the engine quickly get rid of the inefficient working range, save fuel and effectively improve the driving quality. Because P0 motor transmits power to the wheels in series, the motor can’t drive the wheels independently without the engine, so there is no pure electric driving mode. In addition, the P0 motor is flexibly connected with the crankshaft through a belt, so the ceiling for applying force to the engine and recovering kinetic energy power is low.

"2020 modified Mazda CX-5 2.5L automatic four-wheel drive smart model"

  Audi SQ7 TDI and Mazda i-Eloop belong to P0 architecture. Because P0 architecture has low transmission efficiency and the motor can’t directly drive the wheels, P0 motor usually appears as an auxiliary in the field of new energy vehicles. There will be corresponding analysis and cases in the following.

◆P1 architecture: independently developed/highly integrated.

  P1-based motor is located at the rear end of the engine crankshaft, which replaces the traditional flywheel. Besides inheriting the function of flywheel to store energy and inertia outside the engine power stroke, P1-based motor has similar functions as P0-based motor, and also supports engine start and stop, braking energy recovery and power generation, and auxiliary power output.

Honda IMA hybrid system

  Compared with P0 architecture, P1 architecture is more compact, and its motor is integrated in the engine housing. The design needs to consider the volume of the engine and the layout in the engine room. Because different gearboxes need corresponding design schemes, the research and development and manufacturing costs of P1 motor are relatively high. Existence is reasonable, and high investment often corresponds to high return. The engine crankshaft acts as the rotor of P1 motor, which has higher power transmission efficiency, better fuel saving effect and more obvious improvement on driving performance. In addition, P1 motor can apply auxiliary braking torque through electromagnetic field adjustment on downhill section to improve safety.

Home of the car

  Although they are in different positions, P0 and P1 are connected with the same disease. As long as the motor rotates, the engine crankshaft must rotate, so the motor can’t drive the wheels alone, and there is no pure electric driving mode. In the kinetic energy recovery and sliding mode, the kinetic energy is wasted because the crankshaft must be driven to idle, and the noise and vibration are also increased because of the internal combustion engine following.

"2020 Mercedes-Benz E-Class (imported)"

  A few days ago, the E350 model launched by Mercedes-Benz overseas adopted a 2.0T 4-cylinder engine code-named M254, and added 48V light mixing technology in the electrification transformation process. The ISG motor equipped with it has a maximum power of 12kW and a peak torque of 180N·m, which alleviates the performance of turbine lag when the wheels start and accelerate. This system is a typical P1 architecture. Officially, the motor is named "FAME" (modular engine). Some foreign media have speculated that this motor will appear on other PHEV models.

◆P2 architecture: modular design/strong fuel economy and wide application. 

  The P2-frame motor is located between the engine and the gearbox. Because it is not necessary to be integrated in the engine housing like P1 motor, the layout can be more flexible. The structure can be equipped with 1-2 clutches between the engine and the gearbox, which can be divided into three layout modes: ① Single-clutch structure in which the motor is arranged in front of the clutch, and the motor plays the role of assisting, parking power generation and starting the engine, which is similar to P1 structure; (2) Single-clutch structure in which the motor is arranged behind the clutch, so that the motor can drive the vehicle independently, recover braking energy, generate electricity and assist; ③ The motor is arranged in the middle of the dual clutch structure, so that the motor can drive the vehicle independently, and can also start the engine or park for power generation.

  P2 architecture has strong compatibility and can be matched with all gearboxes (including manual gearboxes). P2 architecture is widely used in hybrid vehicles at present, and many parts suppliers have mature solutions. Take Borgwarner’s P2 motor module as an example. It integrates a dual-mass flywheel and an engine release clutch, which can disconnect the clutch and the motor direct-drive vehicle. It can convert an internal combustion engine-powered vehicle into a hybrid vehicle without changing the engine and gearbox, which means that car companies can expand the power combination of vehicles and enrich the product line of hybrid vehicles with less investment, shorter time and greater flexibility.

"Audi A3 e-tron Power System"

Audi (import) Audi A3 new energy (import) 2017 Sportback e-tron comfort type

"2017 Audi A3 new energy (imported) Sportback e-tron comfort type"

  Audi A3 e-tron is a representative model with P2 architecture. It is equipped with a 1.4T engine and a permanent magnet synchronous motor with a maximum power of 75kW. The battery capacity of the car is 8.8kWh, and the pure electric cruising range is 50km under NEDC condition.

◆P3 architecture: efficient power transmission and large space occupation. 

  The P3-frame motor is located at the output end of the gearbox, and its pure electric drive and kinetic energy recovery efficiency are high, and the effect of rapid acceleration is very direct. In terms of function, P3 motor can realize braking energy recovery and pure electric drive vehicles. Because the motor can’t be integrated with the gearbox or engine, it needs to occupy extra volume, so P3 architecture is more suitable for rear-wheel drive, and there is enough space for layout.

Home of the car

  Compared with P0, P1 and P2 architectures, P3 architecture’s power transmission path does not pass through the gearbox, so the efficiency of pure electric drive and braking energy recovery is higher, and at the same time, the working time of the gearbox is reduced, which is helpful to prolong its service life. But the problem is also obvious, P3 motor can’t realize parking charging, and the shortcomings of outdoor camping and other use scenarios are exposed.

Home of the car

  The representative model is BYD Qin PHEV, which is a parallel hybrid car with P3 motor as the core. With the original large-capacity battery setting, it not only meets China’s pure electric endurance of 50km for PHEV, but also can stack the performance of engine and motor to achieve stronger power output.

◆P4 architecture: realize four-wheel drive.

  P4 frame motor and engine do not drive the same shaft, thus helping the vehicle to realize four-wheel drive. It can be a motor that drives the front axle/rear axle, or it can simply cancel the axle just like Acura NSX, and directly use two hub motors to drive the wheels. P4 architecture is similar to P3 in function, which can realize braking energy recovery and pure electric drive vehicles.

"2020 BMW i8 Extreme Night Meteor Limited Edition"

  P4 architecture is mostly used in plug-in hybrid vehicles, and sports cars are more commonly used, such as porsche 918 Spyder, Acura NSX, BMW i8 and other sports cars. Take BMW i8 as an example. This 1.5T three-cylinder engine squeezes out the maximum power of 231Ps and the maximum torque of 320 N m. The maximum power of the permanent magnet synchronous motor on the front axle is 131Ps and the peak torque is 250 N m. It is equipped with a two-speed automatic gearbox to adjust the torque. The official acceleration time of 0-100km/h is 4.6s, which brings excellent power and can effectively reduce fuel consumption.

◆Ps architecture: parasites of double clutch

  P3 motor is coupled at the output end of the gearbox, and Ps motor is directly integrated inside the gearbox. Because of the close location distribution, Ps architecture is easily confused as P3 architecture. Ps architecture is based on dual-clutch gearbox, which uses the characteristics of dual-clutch gearbox with two input shafts to integrate the motor on one of the shafts, and can realize pure electric drive vehicle and braking energy recovery.

Home of the car

"PS architecture power transmission mode"

  The motor, clutch and reducer of Ps structure are put into the same shell, which is more fuel-efficient and smoother. But the disadvantages are also obvious, because the even shaft of the dual-clutch gearbox bears more torque than the odd shaft, which will lead to the inconsistency between the two shafts and the clutch wear; In addition, the integration of the motor into the gearbox will increase the maintenance cost, because it is the gearbox assembly that needs to be disassembled regardless of gearbox failure or motor failure.

"2021 Borui New Energy 1.5T ePro Leading Edition"

  At present, among China brand car companies, Great Wall, Chery and Geely are all studying DHT gearbox, which is the cornerstone of Ps architecture. Taking Geely Automobile as an example, the 1.5T+7DCTH plug-in hybrid system of Geely ePro family models has the characteristics of high motor efficiency and high powertrain matching, and has the comprehensive advantages of high efficiency, excellent space and good quality (high cost performance). Among them, the efficiency of Ps frame motor is 97%, which is about 2% higher than that of P2 coaxial motor. The working speed of Ps frame motor is not limited by the engine, and the engine and motor can work in the high efficiency area at the same time, which can effectively reduce the fuel consumption of the whole vehicle.

Combined frame motor

  Brothers in battle, fathers and sons in battle, and motors with a single architecture all have shortcomings more or less, so combining two or more architectures of motors becomes the best solution at present. On P3 or P4 frame vehicles, it is necessary to install another motor for the engine in order to perform the engine start-stop and power generation functions, so many hybrid vehicles have two motors, forming a combined configuration of Px+Py. For example, WEY P8 has a BSG motor at the front end of the engine and a permanent magnet synchronous motor at the rear axle, which belongs to P0+P4 configuration. Let’s understand the technical characteristics of the combined structure motor through the development of domestic and foreign car companies and the analysis of car models.

◆ Volvo PHEV Technology Review and T8 Powertrain Analysis

Home of the car

  In 2013, Volvo’s first-generation plug-in hybrid (PHEV) technology was applied to S60 PHEV models, adopting P0+P4 architecture, consisting of a BSG motor with 15kW engine front-end power and a 50kW permanent magnet synchronous motor with rear drive axle; In 2015, Volvo’s second-generation PHEV technology was applied to XC90 PHEV models, adopting P1+P4 architecture, consisting of an ISG motor with a power of 35kW and a permanent magnet synchronous motor with a rear drive axle of 60kW; At present, Volvo adopts the third generation PHEV technology based on CMA vehicle platform, and adopts a hybrid powertrain composed of an engine matching P2 motor.

Home of the car

  As for the specific vehicle type, Volvo XC90 PHEV adopts a hybrid powertrain with P1+P4 architecture. The front axle of the vehicle is equipped with a gearbox integrated motor named C-ISG (Crank-integrated starter generator), which has three functions of start-stop control, power generation and assistance, and the rear axle is also equipped with a motor with the maximum power of 65kW. At present, Volvo’s PHEV models cover cars, station wagons and SUVs, all of which use modular PHEV powertrains.

◆ Evolution history of BYD DM system and analysis of the third generation DM system.

  Since 2008, BYD’s DM system (Dual Mode system) has been upgraded twice. At present, the upgrade of the plug-in hybrid of the third generation DM is not only in terms of power, but also in terms of "performance" attributes of the whole BYD model after the "542" plan was put forward from the second generation DM system.

  "High power consumption" is an obvious problem in the second-generation DM system. BYD thinks that BSG motor+electronic control system can solve the problem of "avoiding the inefficient area of the engine", assist the vehicle to generate electricity, make the whole energy flow system more balanced, and bring better acceleration performance, so the brand-new "BSG architecture" system is one of the core upgrades of this generation DM3.

  The biggest purpose of BSG motor of the third generation DM system is not only to provide start-stop function servo for the engine, but also to charge the power battery while driving, and it can also be used to improve the acceleration performance. When the vehicle is driving in the all-electric drive mode, when the engine is involved, the BSG motor will drive the engine to start, so as to reduce the shock and assist in gear shifting.

Full text summary

  With the stricter emission standards and the support policies for new energy vehicles, OEMs pay more and more attention to the new energy market. Compared with the development of a brand-new hybrid system, the P2 technical route with modular design does not need to change the existing structure, is easy to integrate and is suitable for matching all gearboxes. Even if the fuel saving effect is not as good as that of parallel connection, the fuel consumption can be reduced at a lower cost, which has become a "shortcut" for many car companies.

Meet Yunnan golden monkey at Baima Snow Mountain in Yunnan.

"Listen, the leaves rustle, that’s the voice of the monkeys approaching. We will hurry up the mountain and try to observe the Yunnan golden monkey at close range. " Under the urging of Lai Jiandong, the stationmaster of Yunnan Baima Snow Mountain Wildlife Rescue Station, 13 students from Tsinghua University Institute of Economics and Management who participated in the summer social practice accelerated their pace.

Walking in a hurry, just to see the true face of the "gentleman" Yunnan golden monkey.

Yunnan golden monkey is a national first-class protected wild animal and an endangered species endemic to China. As the highest-altitude primate in the world, Yunnan golden monkey is only distributed in 7000 square kilometers of high-altitude virgin forest between Lancang River and Jinsha River at the junction of Tibet and Yunnan. It is regarded as the flagship symbol of biodiversity in northwest Yunnan and one of the most representative species in Yunnan.

"The reason why they are called’ gentlemen’ is that Yunnan golden monkeys are’ civilized and elegant’, and generally do not attack and harm humans, nor do they go to villages to destroy them. Yunnan golden monkey will not scratch or bite. However, it is still necessary to keep a distance to avoid injury and infection. " Lai Jiandong introduced while walking.

In 1960s, Yunnan golden monkey was once considered extinct, until 1964, when experts from Kunming Institute of Zoology, Chinese Academy of Sciences conducted an animal survey in Deqin County, Diqing Tibetan Autonomous Prefecture, they collected skins of Yunnan golden monkey, which confirmed that this species was not extinct. Yu Jianhua, a former hunter and 72-year-old monkey guard captain, recalled the Yunnan golden monkey and said, "When I was a child, I just heard from the old people in the village and never saw it with my own eyes."

In order to better protect Yunnan golden monkey, since 1983, Yunnan Province has successively established four protected areas, including Baima Snow Mountain, Yunlong Tianchi, Lanping Yunling and Lijiang Laojun Mountain, with a total area of over 478,000 hectares. In recent years, 990.66 hectares of Yunnan golden monkey habitat outside the protected area has been included in the protection scope, creating good conditions for the recovery and growth of Yunnan golden monkey population.

From 1997 to 1999, the special investigation of Yunnan golden monkey organized by Yunnan forestry authorities showed that the natural population of Yunnan golden monkey was 13 groups, with a population of 1400-1700. After years of protection, the population of Yunnan golden monkey has increased to more than 3300. "Baima Snow Mountain National Nature Reserve is the largest Yunnan golden monkey reserve in China, and it is also a paradise for Yunnan golden monkeys. At present, the number of Yunnan golden monkeys here has reached more than 2,500. " Lai Jiandong said.

Walking to an open field in the mountains, you can see dozens of Yunnan golden monkeys stopping on branches or chasing and playing in the mountains. The fur of Yunnan golden monkey is not golden yellow, but mainly gray-black and white. There is a pointed black crown hair on the top of the head, blue-gray or pink around the eyes and nose, and the nose is dark blue. The back, hands, feet and tail of the body are gray-black, and there are sparse gray hairs on the back. The abdomen, neck, buttocks and inner limbs of the body are all white.

"Usually, a Yunnan golden monkey population consists of an adult male, several adult females and several young monkeys. Adult male individuals are bigger than female individuals, and their buttocks are full of white hair, which is dubbed as’ white shorts’. After learning the survival skills, young monkeys will also leave the ethnic life. In the observation, we also found an all-male unit, which is composed of all male individuals. The members include the defeated and retired old male monkeys and the young male monkeys who have not formed a family. " Lai Jiandong introduced.

Over the years, Baima Snow Mountain National Nature Reserve has kept observing Yunnan golden monkey and steadily promoted the work of popular science education.

There is a popular science education base for Yunnan golden monkey in the nature reserve, covering an area of 334.16 square kilometers, which is the only place in the world where you can watch Yunnan golden monkey at close range. In the popular science education base, there are rare and protected plants such as Taxus yunnanensis and water green tree. In addition to Yunnan golden monkey, there are more than 10 rare and protected animals such as forest musk deer, red panda and black-necked pheasant. The forest coverage rate here is as high as 98.2%, which is called "a paradise for animals and plants". In the exhibition hall of the popular science education base, there are also many kinds of rare and protected animal specimens, among which the Yunnan golden monkey specimen with the largest number and the most complete scale is very precious.

As a window for close observation of Yunnan golden monkey, the popular science education base provides rich natural education resources. This summer social practice activity jointly organized by Zhongjin Public Welfare Foundation and Tsinghua University Institute of Economics and Management provides a useful attempt for students to explore how to effectively realize the harmonious coexistence between man and nature in a specific ecological and economic environment.

"The theme of this social practice is’ green and low carbon+biodiversity+rural revitalization’. In Lanping Bai Pumi Autonomous County, Zhongjin Public Welfare Foundation cooperated with China Green Carbon Sink Foundation to develop the’ carbon neutral forest’ project, and planted 112,000 fir and spruce trees. The project has not only achieved the goal of coping with climate change, but also an effective nature-based means to protect biodiversity. Usnea, a parasitic plant growing on fir and spruce, is one of the foods of Yunnan golden monkey. In order to allow students to visually observe the golden monkey, we chose to study in the popular science education base. " Lin Baichuan, team leader and member of the secretariat of CICC Public Welfare Foundation, introduced.

At the same time, CICC Public Welfare Foundation coordinated professional tutors in finance, economics, sociology and ecology, and designed four modules, namely, green finance, green transformation, community development and ecological protection, to help students conduct in-depth research on hot topics such as green and low-carbon development, conservation of germplasm resources and biodiversity, and unified carbon market construction, so as to enhance their knowledge and understanding of the country’s strategic layout, policy orientation and market behavior.

The eating of usnea by Yunnan golden monkey is also based on years of observation in the reserve. At present, there are 25 monkeys in Xiangguqing Yunnan Golden Monkey Protection Team in Baima Snow Mountain Nature Reserve, and its captain Yu Jianhua has been following Yunnan Golden Monkey for 28 years, rain or shine. "The monkey is very smart, knowing that there are pineapples here to eat, and some people are busy watching. Every morning, they come over to eat and play. We will follow them when they go up the mountain. We won’t go home until the monkey sleeps after 8 pm, and we will come to the monkey again at 5 am the next day. "

This group of relatives and observable monkeys is called Xiangguqing Yunnan golden monkey display group. More than 150 baby monkeys have been born, and the survival rate is over 85%. 125 Yunnan golden monkeys have been released in groups, which has well supplemented the number of wild monkeys and promoted gene exchange. At the same time, the number of people watching Yunnan golden monkey at close range has exceeded 300,000, which has greatly enhanced the popularity and influence of Yunnan golden monkey, and also provided a foundation for relevant experts and scholars to study the behavior and ecology of Yunnan golden monkey and promote the better protection of wild population.

Protecting wild animals and plants such as Yunnan golden monkey has brought good ecology and benefited residents in nearby communities. Bee farmer Yu Xinhua earns 20,000 to 30,000 yuan a year by beekeeping and planting Chinese herbal medicines, which is much higher than before. "I now have three bee farms with 60 boxes of bees, and the filtered honey can be sold to 140 yuan per kilogram. Good honey in a good environment is very popular, and some customers let me send it by express delivery. " Yu Xinhua introduced.

In the world natural heritage site with three parallel rivers, Yunnan golden monkey and 20% higher plants and animals in China live happily and roam the mountains. This vast alpine virgin forest ecosystem is a true portrayal of the harmonious coexistence between man and nature. (Huangshan yangshua)

Li Keqiang: Mass entrepreneurship and innovation are the new engines of China’s economy.

  On the afternoon of January 26th, Li Keqiang, Premier of the State Council of the People’s Republic of China hosted a forum to listen to the opinions and suggestions of experts, scholars and business people on the Government Work Report.

  On the afternoon of January 26th, Li Keqiang, Premier of the State Council of the People’s Republic of China hosted a forum to listen to the opinions and suggestions of experts, scholars and business people on the Government Work Report. 

  Beijing, January 27th (Reporter Feng Yue) According to the Voice of China News and Newspaper Summary, Li Keqiang, Premier of the State Council of the People’s Republic of China hosted a forum yesterday to listen to the opinions and suggestions of experts, scholars and business people on the Government Work Report. The State Council Vice Premier Zhang Gaoli attended the forum.

  At the symposium, experts and scholars from universities, scientific research institutions and financial institutions expressed their opinions on the current economic situation. Business leaders from the Internet, electronic information, venture capital, building materials and other industries discussed their views on industry development and economic trends respectively. Li Keqiang said: "While stabilizing macro-policies, we focus on interval control and directional control. In fact, in the past two years, the most important indicator we have adopted is to stick to the employment rate. We are most pleased that employment has increased by 13 million people, which is very important for a developing country. "

  Faced with the current slowdown in growth and difficulties in the operation of some enterprises, experts suggest that structural reforms should be used to solve structural contradictions, and high-end industries such as modern service industries should be developed to improve economic efficiency. Li Keqiang said: "When we enter the new normal, we can’t pursue higher speed, but we should put more energy into improving quality and efficiency. We talk about a stable macroeconomic policy to ensure that in a reasonable range, we always grasp it in this process and use more energy to promote comprehensive deepening reforms and promote structural reforms. "

  Tsinghua University, Wu Xiaoling and others proposed to implement a moderately tight monetary policy, accelerate financial reform and stabilize market expectations. Li Keqiang said: "What Comrade Wu Xiaoling said gives us a good inspiration. We always talk about relaxing access to finance on the one hand and strengthening supervision on the other. In fact, many aspects of our financial supervision are unnecessary or even should not be. In this respect, it just hinders market access. Our government has to do the government’s business. We always give orders to the market and always take enterprises to plan, but the government has done nothing of its own. Think about it, some of what we say should not be, some may be empty talk, and it may be meaningful to give a signal at most. The operation of enterprises should be planned by themselves, so we should concentrate on doing the government’s things well. "

  At the symposium, several entrepreneurs put forward suggestions on encouraging innovation, developing venture finance, promoting enterprises to "go global" and reforming state-owned enterprises. Li Keqiang emphasized: "How can we let the masses start businesses and innovate? I think this is a new engine of China economy. If 120 million people can start businesses and innovate, what changes will this bring to our entire economic structure? If we say that in the first 30 years (reform and opening up), we relied more on hard work, and then we should rely more on wisdom, relying on the government to simplify administration and decentralize power, lowering the market entry threshold, so that people who are willing to start businesses can start businesses, and then strengthen supervision after the event in the market. If we say that mass entrepreneurship and innovation are mobilized, this requires government reform. "

Jietu Shanhai L6 sells for 123,900 yuan, and the electric hybrid SUV for young people.

On August 25th, the 7th Jietu Fan Culture Festival and its launch event was held in Guilin. The new car was released in three versions, with a guide price of 123,900-144,900 yuan and a trade-in price of 100,900-116,900 yuan (including the national trade-in subsidy). As a compact plug-in SUV, the price of Jietu Shanhai L6 is quite competitive.

Jietu Shanhai L6 is the second model of Jietu Shanhai series, but it adopts a brand-new design language in design, including the paint color, which is also very individual. In addition to the common black, white and gray, the new car also offers low saturation and high brightness colors such as vanilla blue and aquamarine blue, which look very fashionable. The upper grille of Jietu Shanhai L6 adopts a closed design, which is more like a new energy vehicle compared with Big Brother. The vehicle mainly gets air through the lower grille. The light group of the new car is also very interesting. After the daytime running lights are lit, they are staggered, showing the shape of "one" and "J", which looks very recognizable. Perhaps the designer also means "a smooth journey". At the same time, the skirt line with obvious lines and beautiful car shoulders improve the sports atmosphere of the whole car a lot. Therefore, from the design point of view, Jietu Shanhai L6 is a car that is very suitable for young people or young families.

Entering the car, Jietu Shanhai L6 continues the style of Jietu Shanhai L9, adopting a symmetrical design, but the lines are more concise, and some bright colors are added to make it look more fashionable. The new car is equipped with a 15.6-inch floating central control screen, which we have experienced in real cars before. Whether it is the built-in application, operational response speed or voice interaction experience, this screen has performed well. The quick control of the air conditioner at the bottom of the screen adopts the lever type, and the damping feeling is good, which is a bit like flying an airplane. Then there is the mobile phone wireless charging area, which supports 50W wireless fast charging, and there is a mobile phone cooling vent below, but it is a pity that only the left driver side supports fast charging, and the right panel does not have wireless charging function. It is worth mentioning that Jietu Shanhai L6 has spent a lot of thoughts on storage. There are 32 storage spaces in the cockpit of the whole vehicle, which is convenient enough for long-distance travel or daily use.

In terms of power, Jietu Shanhai L6 is equipped with Chery’s fifth-generation Kunpeng Super Hybrid C-DM, which is powered by a combination of 1.5T engine+stepless hybrid DHT+ front single motor. Among them, the maximum power of the motor is 150kW, and the maximum torque is 310N·m, which makes the acceleration of Jietu Shanhai L6 easily enter the 7-second level. By carrying a 19.43kWh battery pack, the new car can achieve a pure battery life of 125km(CLTC working condition). Thanks to the engine thermal efficiency of 44.5% and the gearbox mechanical efficiency of 98.5%, the fuel consumption of Jietu Shanhai L6 is only 5.2L per 100 kilometers, which also makes the comprehensive endurance of this car reach 1400km. For most of my friends, it’s not necessary to replenish energy on the way back to their hometown.

It can be said that the overall product strength of Jietu Shanhai L6 is very good, and the price is also very attractive if the old one is exchanged for the new one. I think there is another very important point, that is, Jetway’s "Travel Plus" strategy. When you drive a Jetway bus, you can enjoy all kinds of scenic spots tickets and hotel discounts, as well as Jetway stations all over the country, which can provide users with one-stop services of catering, accommodation and car maintenance. This is also very attractive to young people who love to travel.

It has been the world’s largest producer and consumer of machine tools for 15 consecutive years, but the domestic share of high-end CNC machine tools is less than 10%.

The industrial machine tool represented by high-end machine tools is the cornerstone of national manufacturing modernization. On September 6, 2024, the mobilization and launching ceremony of "Industrial Machine Tool+"100-line enterprise production and demand docking was held in Changzhou.

The reporter learned from the meeting that China has been the world’s largest producer and consumer of machine tools for 15 consecutive years, but the localization share of high-end CNC machine tools is less than 10%. Experts from the Ministry of Industry and Information Technology and China Academy of Engineering have said that focusing on high-performance manufacturing has become the key to enhance the competitiveness of the industrial machine tool industry. Jiangsu is the province with the largest number of machine tool enterprises in China, and it has the obligation and ability to follow the national industrial machine tool industry and embark on a new road.

The domestic market is huge, but the "high-end" has fallen.

Why is industrial mother machine important?

"Industrial mother machine is a machine for manufacturing machines, a basic and strategic equipment of the country, with a strategic position beyond economic value, at the core of industrial modernization industrial chain, with strong foundation, high complexity, long accumulation, product diversity and other technical characteristics." Guo Dongming, academician of China Academy of Engineering, chairman and chief scientist of Changzhou Longcheng Laboratory of Intelligent Manufacturing, explained that the industrial machine tool is a knowledge-intensive product integrating materials, mechanics, machinery, electronics and computers, and it is a typical progressive innovation field, and the technological upgrading cycle of each generation is about 20 years.

Combing the development of China’s industrial machine tool industry —— After the founding of New China, the machine tool industry has been planned and laid out. Since 2009, China has been the world’s largest producer and consumer of machine tools for 15 consecutive years. According to the data of VDM German Machinery Industry Network, last year, the output value of machine tools in China reached 25.3 billion euros, accounting for 31% of the world; Machine tool consumption is 23.7 billion euros, accounting for 29% of the world.

However, despite the huge market, domestic industrial machine tools have long been in an embarrassing situation of "low-end melee, mid-end competition and high-end loss", and the bottleneck of industry being controlled by people has never been broken. According to the data of China Electronic Information Industry Development Research Institute, the domestic market share of high-end CNC machine tools in China is less than 10%, which corresponds to the high import of high-end CNC machine tools. In 2022, the imported CNC machine tools cost about 2.5 billion US dollars, and the export amount is about 1.5 billion yuan.

At the same time, western countries have long strictly restricted the export of high-end CNC machine tools. In recent years, with the changes in the international situation, its control of high-end machine tools such as high precision and multi-axis linkage has become more and more stringent, and the situation of being "stuck in the neck" in China is very serious.

"For the manufacturing requirements of high-performance equipment products such as high-end CNC machine tools, simply aiming at geometric accuracy can no longer meet the requirements of high-performance manufacturing, and we must seek geometric and performance integrated manufacturing with the goal of ensuring precise performance." Guo Dongming said that focusing on "high-performance manufacturing" has become the key to enhance competitiveness. Specifically, material properties need to include the use of difficult-to-machine materials such as super-sticky, super-hard and super-brittle. Geometric mechanisms need to ensure structural rationality, reliability and tolerance of key geometric dimensions and shapes. Working conditions need to meet complex and extremely demanding working environments and working conditions for a long time, and manufacturing processes need to ensure the machinability of products, the accuracy and efficiency of processing and assembly.

Jiangsu’s industry is developed, and it has the conditions of "pursuing high".

On the afternoon of September 6, the reporter came to Aipaier (Changzhou) CNC Technology Co., Ltd., and Zou Jianhua, the general manager of the company, revealed excitedly: "We have just been rooted in Changzhou for 4 years, and we will usher in an industrial breakthrough. The self-developed five-axis machining plane for turbine blades has broken the monopoly of foreign technology and will be put into production soon!"

Zou Jianhua told reporters that the aero-engine with the most technical content and industrial value in turbine machinery (dynamic fluid machinery) is known as the "crown of modern industry", and its related blade manufacturing is more demanding on the cutting performance, high stability and high precision of the mother machine because of its high power, high torque and high speed, and it is known as the "jewel in the crown", and what they want to do is to "take off this pearl".

"Keeping a close eye on the’ stuck neck’ link, we focus on the overall solution of aero-engine blades." Zou Jianhua introduced that the company has invested more than 20 million yuan in research and development, successfully broke through a number of basic technologies and key common technologies of high-temperature alloy aero-blade CNC machine tools, and established a research and development platform and talent training base for CNC equipment. In terms of high rigidity, high precision and high reliability of machine tools, it is comparable to top international brands, and its work efficiency is 25% higher than that of Haas four-axis machine, which was widely used before, while its price is less than 1/3 of that of foreign imported brands.

Zou Jianhua admits that this enterprise founded in Shenzhen landed in Changzhou, which is precisely because of its industrial ecology.

Jiangsu is an important R&D and production base of industrial machine tools in China, and it is also the province with the largest number of machine tool enterprises in China. In 2023, the operating income of industrial machine tools enterprises above designated size in the province exceeded 100 billion yuan, accounting for about 1/5 of the whole country. Exports are even more outstanding. In the first half of 2024, the export volume of high-grade CNC machine tools in Jiangsu Province accounted for 40% of the country.

"Our province has taken the initiative to connect with the national industrial machine tool industry development action plan and has included industrial machine tools in the’ 1650′ industrial system for key cultivation." Li Jian, the second-level inspector of the Provincial Department of Industry and Information Technology, said that last year, our province issued a policy document for the high-quality development of the industrial machine tool industry, further accelerating the key technology research, innovation platform construction, product promotion and application, and enterprise gradient cultivation.

At present, the industrial chain of Jiangsu industrial machine tools is relatively complete, with six upstream and downstream links, including basic components, functional components, tool accessories, control system, whole machine manufacturing and complete equipment integration, covering four major fields, including cutting machine tools, forming machine tools, special machine tools and additive manufacturing equipment, and has cultivated more than 70 "little giant" enterprises specializing in industrial machine tools.

Taking Changzhou as an example, Xue Qinglin, deputy director of Changzhou Municipal Bureau of Industry and Information Technology, counted that the scale of the industrial machine tool industry in Changzhou has exceeded 40 billion yuan, and there are a number of internationally renowned enterprises such as Emmanuel, George Fisher and Henglun, and Xixia Villa "Tool Town" is even more famous throughout the country.

It can be seen that Jiangsu has the "family background" and the will to lead the industry to new heights.

All parties jointly tackle key problems and seek technological breakthroughs.

So, how to take the road of high-performance manufacturing? What is the key to technological breakthrough?

At present, the industry has reached a consensus that the lack of "four characteristics" of industrial machine tools, such as process adaptability, reliability, accuracy retention and accuracy stability, is the main reason for the weak competitiveness of domestic high-end machine tools.

Besides external reasons, the deficiency of "four natures" also comes from some internal factors, such as top-level design, long-term planning and macro-control at the industry level, disjointed high-end supporting facilities and weak investment, lack of core technology and lagging product iteration, scattered innovation resources and insufficient talent reserve.

No matter from the national or Jiangsu level, the key to "breaking the game" is first of all technological innovation and concentrating on breaking through the "stuck neck" link.

"Compared with imported machine tools, the gap in accuracy retention of domestic machine tools is the most obvious." Wang Yongqing, executive director of Longcheng Laboratory of Intelligent Manufacturing, brought a solution of "quick evaluation" during the activity. The laboratory is currently establishing an intelligent monitoring and operation and maintenance platform for industrial mother machine clusters based on cloud and edge collaboration to realize remote monitoring, big data analysis and intelligent operation and maintenance of high-end machine tool equipment clusters.

Technology breaks down and needs to be blessed by innovative carriers. Longcheng Laboratory is an innovative platform with high-end machine tools and manufacturing technology as its core, which was established in cooperation with Dalian University of Technology and General Research Institute of Mechanical Science.

In Jiangsu, there is more than one such innovation platform. During the event, the latest innovations of various platforms were displayed-

Ou Yi, a researcher at South Institute of Technology and deputy director of the Key Laboratory of Generic Technology for CNC Machine Tool Functional Components of the Ministry of Industry and Information Technology, released a controllable loading technology that can simulate a variety of complex actual working conditions at the same time. Based on this technology, he invented complete sets of equipment such as precision retention, reliability and life, and surface detection, which filled the gap in the industrial chain.

Industrial mother machine needs software support. Nina Dai, deputy general manager of Jiangsu Advanced Composite Technology and Equipment Innovation Center, introduced a set of simulation software and CAM software system independently developed by the center, which can realize real-time simulation and prediction of path planning of fiber reinforced composites and printing process of porous components of composite materials in aerospace manufacturing, and provide software support for fiber reinforced composites …

Miao Changxing, the first-class inspector of the First Division of Industrial Equipment of the Ministry of Industry and Information Technology, revealed that the major national science and technology project "High-end CNC machine tools and basic manufacturing equipment" has been launched first this year, and it is expected that after three years, another batch of "innovative fruits" will be produced.

Strengthen the adaptation between supply and demand and accelerate the independent upgrading.

In addition to technological breakthroughs, it is another upgrade path to break the foreign blockade and promote the high-end machine tool equipment from "usable" to "durable" and then "easy to use" by taking the user’s process demand in key areas as the traction, intensifying efforts to promote the pairing research between the supply and demand sides of industrial mother machines and promoting the popularization and application of independent innovative products.

For the demand side, it is very willing to apply autonomous equipment. "Compared with manual grinding chamfering, the gear shaft chamfering machine has the advantages of reducing labor intensity, consistent product chamfering shape and isolating environmental hazards, so we need to realize chamfering mechanization and automation." Zhu Baizhi, director of Nanjing High-speed Gear Manufacturing Co., Ltd., said frankly that domestic enterprises are more willing to use domestic solutions with higher cost performance than foreign high technical costs and "tough" parts replacement requirements.

By concentrating limited resources, it has become the focus of all localities to take the lead in making breakthroughs in key areas such as aviation, aerospace, aviation development, and new energy vehicles, and to strengthen the docking between supply and demand in a targeted manner.

Changqing Technology, located in Changzhou, is a high-tech enterprise engaged in the development and application of lightweight composite materials, mainly providing supporting products for the interior decoration of rail transit vehicles and the interior and exterior decoration of buildings. Recently, with the continuous recovery of the global rail transit market, the company has received many processing orders for complex products at home and abroad, but there is a gap in production equipment, and enterprises urgently need to buy a five-axis industrial mother machine with higher precision. Under the matchmaking of the local industry and information department, the enterprise indexes through the list of supply and demand, and soon finds an independent brand manufacturer.

For the supplier, through the "pairing" adaptation, the traditional process is accurately and efficiently modified, which not only saves the cost, but also significantly increases the order. Yun Yun, deputy general manager of Jiangsu Desu Intelligent Machinery Co., Ltd. revealed: "The company’s orders have increased by more than 20% compared with the same period last year."

In order to promote the supply and meet the needs. The list of production and demand released at the meeting contains more than 2,000 items of supply and demand. The supply list includes key industrial machine tool enterprises, supply capacity and products, application scenarios, etc. The demand list includes key user enterprises, required technologies and products, application scenarios, etc.

Industrial development needs to form a more unified and powerful ecology. At the meeting, 35 units jointly launched the Initiative of Promoting the Application Development of "Industrial Machine Tools+100 Enterprises", which consolidated development consensus from six aspects: strengthening pairing research, strengthening technology supply, strengthening demand traction, strengthening exchanges and cooperation, strengthening financial support and strengthening industry self-discipline, and accelerated the construction of an industrial machine tools application ecological community. According to industry insiders, under the background of the country’s promotion of large-scale equipment renewal, coupled with the "industrial mother machine+"production and demand docking activity that lasted for more than three years, it is expected that the industry as a whole will increase its market demand by 100 billion yuan.

Guo Dongming suggested that according to the regional industrial advantages, we should increase policy support, guide the development direction of enterprises, build a number of industrial machine tool industrial clusters with distinctive industrial characteristics and clear enterprise tracks, and promote China’s industrial machine tool industry to truly become "world-class".
