Ten technical trends of auto parts

Technology is the driving force of automobile development. 2016 is a critical year for the transformation of traditional automobile industry. The deep integration of Internet, semiconductor, software algorithm and other auto enterprises has brought new changes and new trends to automotive and automotive parts technology. Then, how will the new automotive parts and components develop in the future and where to lead the car.

Engine power lift out "combination boxing": two level Turbocharging Technology

In recent years, small displacement engines have been highly praised by many automobile companies. Turbocharging technology has made outstanding contributions to the power upgrading and fuel economy optimization of small displacement engines, and has gradually become a technological trend. With the continuous improvement of environmental standards, emission regulations and engine technology, a variety of technology combinations to enhance engine performance will become one of the trend of future engine technology.

At present, two stage turbocharging has become the focus of discussion of technology booster, including two stage turbocharging (consisting of two and a small turbocharger), turbo supercharger + type, and can greatly enhance the rise of the engine power and torque at low speed, low engine start to solve the problem of insufficient power to improve the performance of the engine, has a great help.

It is understood that the foreign vehicle and related parts enterprises have adopted and studied the two stage turbocharging technology, with high technical maturity. The public will be the first turbocharged and supercharged two types of double engine turbocharging system application in production models; the new Infiniti 3.0LV6 twin turbo engine "VR30" was officially put into operation; Berg Warner continue to promote two stage turbocharging technology (R2S); Honeywell launched the new two stage turbocharging system with two different size of VNT turbocharger. But there are not many domestic high level turbocharger enterprises. Hunan Tianyan invested 4 million 150 thousand yuan in 2015 to carry out research on two stage turbocharger project. At present, 1 projects passed customer performance test. In general, domestic enterprises in the two level turbocharging technology level is not high, facing great challenges.

Direct injection engine emission upgrade "new catcher": gasoline engine particulate trap (GPF)

The direct injection gasoline engine (GDI) in cylinder has been widely used in passenger car because of its good power and fuel economy. However, due to the direct injection of fuel into the cylinder of the GDI gasoline engine, the uneven mixing of oil and gas and the wet wall of the fuel make the mass and quantity of the particulate matter significantly increase.

More and more stringent regulations require a direct injection of a gasoline engine to maintain a stable and low PM emissions in a wider range of conditions. The European VI emission regulations are more stringent on the quality of particulate matter, and the PM limit is reduced to 4.5mg/km. Recently released light vehicle emission limits and measurement methods (the sixth phase of China) also tightened the PM limit requirements, the first stage is 4.5mg/km, and the second stage will be 3mg/km. Although GDI engine technology is progressing, it is difficult to meet the needs of emission regulations upgrading solely by internal purification. Therefore, gasoline particulate filter (GPF) is considered to be the most effective and reliable potential technology to deal with GDI gasoline particulate matter emission limits.

At present, the newly released industry directory of foreign investment (Revised Draft) will transform diesel particulate trap into particle catcher, which means that diesel particulate traps will also encourage foreign investors to invest in GPF. Foreign parts enterprises such as BASF, Faurecia and so on in the study of GPF technology and has been applied in the market, the Volkswagen Group announced in June 2017 will be gradually in the overall popularity of GPF gasoline engine. In fact, many companies develop GPF strategy, but not officially announced across the board layout, domestic enterprises take the GPF line, and your research Weifu and other companies also have the technology, compared with foreign technology gap. With the gradual advancement of emission regulations, the future GPF is expected to become a standard.

The future of new energy vehicle driving technology: hub motor technology

New energy vehicles and traditional cars is not a small difference in the drive mode, mainly driven by a motor, including permanent magnet synchronous motor, motor, wheel hub motor, the hub motor technology is considered to be a new energy driving technology in the future, with broad prospects for development.

The biggest feature of hub motor technology is the integration of power, transmission and braking device into the wheel, which greatly simplifies the mechanical part of the electric vehicle. From a global perspective, Japanese enterprises, the US Department, the German department, the legal system and other car companies all involved. The domestic car companies began to try the wheel motor technology in recent years, but they all stayed in the testing stage.

In recent years, the foreign application of driving wheel motor is mainly embodied in two aspects: one is to tire manufacturers or auto parts manufacturers on behalf of the research team developed the integrated electric system; two is the electric vehicle manufacturer and the wheel motor drive system manufacturers joint development.

The development of the domestic parts enterprises in wheel motor technology, the Asia Pacific shares of European hub motor technology company ELAPHE and set up a joint venture in China, 2017 is expected to realize small batch matching, batch production in 2018; Tianjin Tianhai synchronizer e-Traction Holland Group acquired 100% stake in the company, and the establishment of Hubei Tate electromechanical Co. company in Hubei Jingmen, plans to put into operation in 2017 hub motor.

With the continuous development of new energy vehicles and the continuous promotion of enterprises, the era of hub motor technology industrialization will soon come.

The "high cost performance" scheme of emission upgrading: 48V weak mixed system

The weak mixing system is a low cost and effective energy-saving technology for automobile. At present, vehicle is widely used in 12V power system. This system can achieve energy saving and emission reduction through start stop function and braking energy recovery, but power restricts its energy saving effect. 48V system can be said to be a strengthened version of 12V system. It can support more and more electrical systems on the whole vehicle and play a more effective way to start and stop, so as to reduce fuel consumption.

Therefore, with the more stringent fuel consumption and emission standards, it is the general trend to replace the 12V system used in the current car by using 48V system. At the same time, from the current major vehicle manufacturers and parts manufacturers announced plans, in 2017 will usher in the 48V weak mixed system production of the small climax.

In 2016, the release of the new M4 is equipped with a 48V refine weak mixing system, e4Boost48V power system of Valeo in early 2017 and mass production in China landing, BOSCH launched the second generation 48V light mixing system, and that is the research and development of 48V light mixing system will be put into production in 2017.

In addition, in the key technology of 48V, the various parts and components enterprises have also set up the layout. The Schaeffler 48V start and stop system project has achieved mass production, and at present, its 48V products include 48V electric turbocharger and 48V electric drive bridge. Valeo 48ViBSG power machine, 48V electric supercharger products as the core part of 48V system, also attracted attention oems.

A more accurate "eye" for intelligent driving: 77GHz radar

In the intelligent unmanned driving and development trend, a variety of sensor fusion applications is an inevitable trend in the future, the millimeter wave radar detection has the characteristics of stable performance, less susceptible to object surface shape and color effect and good environmental adaptability, so it will become the main sensor in the future.

The Research Institute PlunkeetResearch predicts that by 2020, the global millimeter wave radar is nearly 70 million, and the annual average annual growth rate of 2015~2020 is about 24%. The main band of Automobile Millimeter Wave Radar for 24GHz and 77GHz, and the 77GHz is more likely to be seen as the future direction of the mainstream, but the 77GHz radar development difficult, at present only in mainland China, BOSCH, TRW, Hella, Delphi and other foreign parts giant master.

Domestic enterprises in the millimeter wave radar and foreign large gap, but the Chinese domain car, Xiamen, four electronic record, the national core technology, science and technology, Beijing naray EDAW and other enterprises have a breakthrough, 77GHz remote anti-collision radar Beijing EDAW production has been assembled in the independent brand car unattended, Shenyang Cheng Tai Limited company of science and technology has made a breakthrough in the development of 77GHz Automobile Millimeter Wave Radar also. Recently, the Ministry of industry and Information Commission commissioned the vehicle information service industry application alliance to carry out the research and test of 77~81GHz millimeter wave radar radio frequency technology.

At present, the 24GHz millimeter wave radar is still the mainstream, and the next three years are the time when the 77GHz millimeter wave radar has completely replaced the 24GHz millimeter wave radar. 2016 is the critical year of millimeter wave radar. Enterprises are strategically laying out the millimeter wave radar resources. In 2017, it will become the harvest time of the automotive millimeter wave radar industry.

The camera makes the car more sensitive: a binocular camera

The vehicle mounted camera is the main vision sensor of the advanced driving assistance system (ADAS). It transforms the image into digital signal, and realizes the perception of the road condition around the vehicle. It helps to realize the ADAS function of forward collision warning, lane departure warning and pedestrian detection.

Vehicle mounted cameras can be divided into single camera, binocular camera, rear view camera, stereo camera and circular camera. The market is mainly single camera. At present, vehicle mounted cameras have become standard in high-end cars. They are mainly used in reversing image system. Vehicle mounted cameras gradually replace the rearview mirror, which is also a trend of development.

At present, the auto parts giant Hitachi, BOSCH, Valeo, Continental, Magna, ZF is the main production enterprise TRW car camera, at the same time, these enterprises continue to increase investment in research and development, and enhance the algorithm on chip, Mobileye is a leading global supplier of visual processing system, the total global market share of more than 90% visual processing. The domestic camera algorithm companies mainly have Minieye, Shenzhen to Maxieye, Nanjing, Kai Chong Chong to science and technology, from science and technology, can realize the function of warning and parking, only to Shenzhen Kai Chong and Zongmu technology before entering the market.

In particular, the binocular camera uses the principle of similar human eyes to determine the distance mainly through the parallax calculation of two images, which is more accurate. The double eye camera product of the Chinese Department has completed the prototype and is conducting a large-scale road test. In order to solve the problem of cost and miniaturization, the future binocular camera will have a broad prospects for development.

Automatic emergency brake technology (AEB)

AEB is a vehicle active safety technology. When the driver does not step on the brake pedal in time, the AEB system will start to automatically brake the car and escort the safe trip.

At present, the global mainstream vehicle plant has its own pre collision safety system, although the name is slightly different, but the implementation effect is basically similar. Most of the international spare parts manufacturers, such as BOSCH, TRW, Delphi and William, also have relatively mature AEB technology. Of course, the domestic brake technology enterprises also began to intensify the development of AEB and related products, such as Wanxiang Group and MINIEYE company jointly released the latest AEB samples, and it is expected to mass production in 2017.

In October 2016, the ten major auto brands including Volkswagen, Audi, BMW, Ford and General Motors signed an agreement. They plan to install AEB system on all new cars that will be sold in the US in the future. Compared with the popularity of AEB in the world, the popularization of AEB in China is relatively slow. However, from the perspective of development, automatic emergency braking technology has been gradually mature and put into the market, and the AEB installation rate is expected to be greatly improved in the next year.

It is reported that China's national standard for AEB has completed the drafting and standard drafting work, and is expected to be released in 2017. The introduction of the new policy will push China's AEB market into high growth.
