1. The engine power is improved to play a "combination punch": two-stage supercharging technology

In recent years, small displacement engines have been highly praised by many automobile enterprises. Turbocharging technology has made outstanding contributions to the power improvement and fuel economy optimization of small displacement engines, and has gradually become a technological trend. With the continuous tightening of environmental protection standards, emission regulations and the continuous improvement of engine technology, the technical solution to improve engine performance by combining multiple turbocharging technologies has become one of the future engine technology trends.

At present, two-stage turbocharging has become one of the hot topics in the field of turbocharging technology, including two-stage turbocharging (consisting of one large exhaust turbocharger and one small exhaust turbocharger), supercharging+turbocharging and other types, which can greatly improve the engine's power and low-speed torque, solve the problem of insufficient power for low-speed starting of the engine, and greatly help to improve engine performance.

It is understood that foreign vehicle and related parts enterprises have adopted and studied two-stage turbocharging technology, with a high degree of technical maturity. Volkswagen took the lead in applying turbocharged and supercharged dual supercharged system engines to mass production vehicles; The new 3.0L V6 twin turbocharged engine "VR30" developed by Infiniti was officially put into production; Borg Warner continues to promote two-stage turbocharging technology (R2S); Honeywell introduces two VNT vortices of different sizes

The latest two-stage turbocharging system for the wheel turbochargers. However, there are not many supercharger enterprises with high level in China. Hunan Tianyan invested 4.15 million yuan in the research of two-stage turbocharger project in 2015. At present, one project has passed the customer performance test. On the whole, domestic enterprises are not at a high level in two-stage turbocharging technology and face great challenges.

2. "New catcher" for upgrading direct injection engine emissions: gasoline particulate filter (GPF)

Direct injection gasoline engine (GDI) is more and more widely used in passenger cars because of its good power performance, fuel economy and other advantages. However, due to the direct injection of fuel into the cylinder of GDI gasoline engine, the quality and quantity of particulate matter emissions increase significantly due to uneven fuel air mixture and fuel wet wall.

More and more stringent regulations require direct injection gasoline engines to maintain stable and low PM emissions in a wider range of operating conditions. The Euro VI emission regulations have more strict restrictions on particulate matter emission quality, and the PM limit is reduced to 4.5mg/km. The recently released Limits and Measurement Methods for Pollutant Emissions from Light Vehicles (China Phase VI) also tightened the requirements for PM limits. The first stage is 4.5mg/km, and the second stage will be 3mg/km. Although the technology of GDI engine is constantly improving, it is difficult to meet the upgrading requirements of emission regulations simply by internal purification. Therefore, the gasoline engine particulate filter (GPF) is considered to be the most effective and reliable potential technology to deal with the GDI gasoline engine particulate emission limits. At present, the newly issued Catalogue for the Guidance of Foreign Investment Industries (revised version) changes "diesel particulate filter" to "particulate filter"

It is intended to encourage foreign investors to invest in GPF in addition to diesel particulate trap. Foreign parts enterprises such as Faurecia and BASF are studying GPF technology and have been applied in the market. Volkswagen Group announced that it will gradually popularize GPF in gasoline engines in June 2017.

In fact, many enterprises have formulated GPF strategies, but have not officially announced the overall layout. There are also enterprises taking the GPF route in China. Weifu, Guiyan and other enterprises also have this technology, which is a big gap compared with foreign technologies. With the gradual promotion of emission regulations, GPF is expected to become the standard configuration in the future.

3. The Future of New Energy Vehicle Driving Technology: Hub Motor Technology

There is no small difference between new energy vehicles and traditional vehicles in the drive mode, which is mainly driven by motor, including permanent magnet synchronous motor, wheel side motor, wheel motor, etc. Among them, wheel motor technology is considered as the future of new energy drive technology, with broad development prospects.

The biggest feature of hub motor technology is that the power, transmission and braking devices are integrated into the wheels, greatly simplifying the mechanical part of electric vehicles. From a global perspective, Japanese, American, German, French and other car companies are involved. Domestic car companies have started to try hub motor technology in recent years, but they are still in the testing stage.

In recent years, the application of wheel motor drive technology abroad is mainly reflected in two aspects: one is the integrated electric system developed by the R&D team represented by tire manufacturers or auto parts manufacturers; The second is the electric vehicle jointly developed by the vehicle manufacturer and the hub motor drive system manufacturer.

Domestic parts enterprises are optimistic about the development of hub motor technology. Asia Pacific shares in European hub motor technology company ELAPHE and establishes a joint venture in China. It is expected to achieve small batch supporting in 2017 and mass production in 2018; Tianjin Tianhai Synchronizer Group acquired 100% of the equity of Dutch e-Traction Company and established Hubei Taite Electromechanical Co., Ltd. in Jingmen, Hubei Province. It plans to put the hub motor into production in 2017.

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

4. "High cost performance" scheme for emission upgrading: 48V weak mixing system

Weak mixing system is a low cost and effective vehicle energy saving technology. At present, 12V power system is widely used in vehicles. This system can achieve energy saving and emission reduction through start stop function and brake energy recovery, but its energy saving effect is restricted by power. The 48V system can be said to be an enhanced version of the 12V system, which can provide support for more and more electrical systems on the vehicle, and more effectively play the start stop function, thus reducing fuel consumption.

Therefore, with the increasingly stringent fuel consumption and emission standards, it is a general trend to replace the 12V system used in current vehicles with the 48V system. At the same time, according to the plans announced by major vehicle manufacturers and component manufacturers, the mass production of 48V weak hybrid system will reach a climax in 2017.

In 2016, the new Ruifeng M4 released by JAC was equipped with a 48V weak hybrid system. Valeo's e4Boost 48V power system will be mass produced at the beginning of 2017 and launched in China. Bosch launched the second generation 48V light hybrid system, and said that the 48V light hybrid system under development will be put into mass production in 2017.

In addition, in terms of 48V key technologies, various parts enterprises have also taken the lead. Schaeffler 48V start stop system project has achieved mass production. At present, its 48V products include 48V electric turbocharger and 48V electric drive axle. Valeo's 48V iBSG all-in-one generator and 48V electronic supercharger products, as the core components of its 48V system, have also attracted the attention of vehicle manufacturers.

5. The "eye" of more accurate intelligent driving: 77GHz radar

Under the development tide of intelligent driving and unmanned driving, the fusion application of multiple sensors is an inevitable trend in the future. Millimeter wave radar has the characteristics of stable detection performance, not easily affected by object surface shape and color, and good environmental adaptability, so it will become the main sensor in the future.

Plunkeet Research, a research institution, predicts that there will be nearly 70 million automotive millimeter wave radars in the world by 2020, with a compound annual growth rate of about 24% from 2015 to 2020. The main frequency bands of automotive millimeter wave radars are 24GHz and 77GHz, while 77GHz is currently considered to be the mainstream direction in the future. However, the development of 77GHz radars is difficult, and only the mainland, Bosch, Trina Solar, Hera, Delphi and other foreign parts giants have mastered it.

There is a big gap between domestic enterprises and foreign enterprises in terms of millimeter wave radar, but Huayu Automobile, Xiamen Yixing, Sichuang Electronics, Guorui Technology, Nalay Technology, Beijing Xingyidao and other enterprises have made breakthroughs. The 77GHz long range anti-collision radar produced by Beijing Xingyidao Company has been installed on its own brand of unmanned vehicles, and Shenyang Chengtai Technology Co., Ltd. has also made breakthroughs in the research and development of 77GHz automotive millimeter wave radar. Recently, the Ministry of Industry and Information Technology entrusted the Vehicle Information Service Industry Application Alliance to carry out the research and test of 7~81GHz millimeter wave radar radio frequency technology.

At present, the 24GHz millimeter wave radar is still the mainstream, and the next three years will be the period when the 77GHz millimeter wave radar will completely replace the 24GHz millimeter wave radar. 2016 is a key year for millimeter wave radar. Enterprises have made strategic arrangements for millimeter wave radar resources. 2017 will be a harvest year for the automotive millimeter wave radar industry.

6. Cameras make cars more sensitive: binocular cameras

The on-board camera is the main visual sensor of the Advanced Driving Assistance System (ADAS), which converts images into digital signals to perceive the road conditions around the vehicle and help to realize the ADAS functions such as forward collision warning, lane deviation warning and pedestrian detection.

Vehicle mounted cameras are divided into monocular cameras, binocular cameras, rear view cameras, stereo cameras and perimeter cameras, and monocular cameras are mainly used in the market. At present, the car camera has basically become the standard configuration on medium and high-end vehicles and is mainly used in the reversing camera system. It is also a development trend that the car camera gradually replaces the rearview mirror.

At present, auto parts giants Hitachi, Bosch, Valeo, Continental, Magna, ZF Trina, etc. are the main manufacturers of car cameras. At the same time, these enterprises continue to increase their investment in research and development, focusing on the improvement of chips and algorithms. Mobileye is the world's leading supplier of visual processing systems, accounting for more than 90% of the global market share of visual processing. Domestic camera algorithm companies mainly include Minieye, Shenzhen Qianxiang Qichuang, Maxieye, Nanjing Chuanglai Technology, Zongmu Technology, etc., which can realize early warning and parking functions. At present, only Shenzhen Qianxiang Qichuang and Zongmu Technology enter the front loading market.

Specifically, the binocular camera uses the principle similar to the human eye to determine the distance mainly through the parallax calculation of two images, which is more accurate. The prototype of the binocular camera product of Zhongke Huiyan has been completed and is undergoing large-scale road test. If the problems of cost and miniaturization are solved, the binocular camera will have a broad development prospect in the future.

7. The active means to escort safety: Automatic Emergency Braking (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, so as to ensure safe travel.

At present, the global mainstream vehicle manufacturers basically have their own pre crash safety systems. Although the names are slightly different, the implementation effects are basically similar. Most international parts manufacturers, such as Bosch, TRW, Delphi, and Webco, also have relatively mature AEB technologies. Of course, domestic brake technology enterprises also began to accelerate the development of AEB and related products. For example, Wanxiang Group and MINIEYE jointly released the latest AEB samples, which are expected to be mass produced in 2017.

In October 2016, ten auto brands including Volkswagen, Audi, BMW, Ford, General Motors and other brands signed agreements to install AEB systems on all new cars sold in the United States in the future. Compared with the international popularization of AEB, the popularization of AEB in China is relatively slow. However, from the perspective of development, the automatic emergency braking technology has gradually matured and been put on the market, and the installation rate of AEB is expected to increase significantly next year.

It is reported that China's national standard on AEB has completed project approval and standard drafting. It is expected to be released in 2017, and the introduction of new policies will certainly promote the high growth of China's AEB market.

8. Help you see what you can't see: augmented reality technology (AR)

Automobile "black technology" has changed the automobile ecology, and augmented reality technology (AR) can be one of them. On the basis of reality, AR technology is an interactive mode brought about by superimposing virtual data in the real environment through computer processing capability and then using the same screen for display.

AR technology is "landing step by step" on the car. At present, the main automotive application products include Head Up Display System (HUD), such as Jaguar Land Rover's HUD technology, which can display maps, virtual driving routes and other contents on the front windshield of the car; Special AR glasses for cars, such as the AR glasses launched by BMW and Qualcomm, enable drivers to see navigation data, driving speed, speed limit prompt, intersection information, etc. while driving. In terms of technology mastery, simple AR technology applications, such as HUD, have been mastered by domestic and foreign auto electronics related parts enterprises, and have mature product applications; Further AR technology is mainly in the hands of Internet and computer software enterprises. Of course, domestic and foreign automobile enterprises are also cooperating with these enterprises to explore the deep integration of AR technology and automobiles.

The development of driverless cars needs AR technology to help achieve better car experience and free people's hands and eyes. Once the pain points of technology application are solved, car AR technology will soon usher in an outbreak.

9. A more "human" car: human-computer interaction technology

The human-computer interaction system is the product of the development of information technology, which realizes the dialogue function between people and vehicles. The future autonomous vehicle is not a cold machine, but a partner endowed with humanity.

Automotive interaction design determines the development level of intelligent vehicles. Under the background of the rapid development of intelligent vehicles at this stage, various automobile enterprises, parts companies, research institutions, etc. pay enough attention to human-computer interaction. International parts giants such as Valeo and Delphi have in-depth research, and domestic automotive electronics enterprises such as Hangsheng, Huayang, etc. have some technical accumulation on this. At present, common human-computer interaction systems include BMW's iDrive, Mercedes Benz's COMAND, Audi's MMI, Volvo's Sensus and Toyota's Remote Touch.

Although human-computer interaction technology is still insufficient, with the maturity of technology, it has gradually popularized from high-end models to domestic mid-level joint venture brand models, such as Changan Ford Mondeo Zhisheng HMI system, GAC Toyota Camry G-BOOK system; The representative of domestic independent brand is SAIC Roewe 350, whose inkaNet 3G intelligent network driving system has more functions.

The human-computer interaction technology makes the car more "human", and the user experience is naturally the most important. This is the foothold of human-computer interaction technology. In the future, somatosensory interaction, eye movement interaction, biometrics, voice interaction, etc. may be the trend of interaction design.

10. Automobile Energy Cycle: Brake Energy Recovery Technology

Brake energy recovery is one of the important technologies of electric vehicles and hybrid electric vehicles, which has been widely concerned. In electric vehicles and hybrid electric vehicles, the movement energy wasted during deceleration and braking can be converted into electric energy through the brake energy recovery technology and stored in the battery, and further converted into driving energy. Therefore, brake energy recovery technology is an important technology to improve energy utilization efficiency and reflect the technical advantages and characteristics of electric vehicles.

At present, electric vehicles and hybrid electric vehicles are basically equipped with brake energy systems. Bosch, Continental, Valeo, Webco and other international parts enterprises have mastered the brake energy recovery technology, and many domestic auto parts enterprises are also developing brake energy recovery systems, and have made certain achievements. In the future, with the development of electric vehicles and hybrid electric vehicles, brake energy recovery technology will be widely used.
