"Intelligence" is the future development trend of automotive electronics

[Electronic enthusiasts news] With the proposal of low-carbon economy and the call for energy saving and emission reduction, green cars, energy saving and emission reduction have become the main theme of the development of today ’s automobile industry. However, in the face of the increasingly prominent traffic congestion problems due to the increase of cars, For safety issues, experts say that only "green" is not enough. Future new energy vehicles should be combined with "smart" vehicles, which will become the development direction of the automobile industry.

Intelligence: Future car development trends

Experts believe that with the development of automotive electronic technology, automotive intelligent technology is gradually being applied. This technology makes the operation of automobiles more and more simple, the power and economy are getting higher and higher, and the driving safety is getting better and better. Therefore, intelligence is the trend of future automobile development.

At the Changchun International Automobile Forum held recently, Dr. Du Jiangling, Dean of GM China (Weibo) Academy of Sciences, pointed out that the challenges facing urban transportation in the future mainly come from three aspects: energy consumption, exhaust emissions, safety and congestion. In response to these challenges, the research on automotive technology will also change from the traditional research on internal combustion engines that use petroleum as energy to the research on the electrification and intelligence of automobiles that use electricity and hydrogen as energy. Du Jiangling believes that in the future, the automotive society will enter the "Internet of Vehicles" era. "Internet of Vehicles" is actually a new network that combines the Internet and the Internet of Things with a car as the main body. The smart car in the "Internet of Vehicles" era has the following characteristics: First, the car can maintain a relatively fixed distance between the cars, which can achieve zero collision; second, the car-to-car teaming is carried out randomly, according to the owner Destinations, through GPS positioning and automatic communication between vehicles, vehicles can temporarily team up or leave the team to improve traffic efficiency. Dr. Deng Weiwen, a Distinguished Professor of the National "Thousand Talents Program" of Jilin University, said that the emergence of semi-autonomous or fully autonomous vehicles in the next few decades will help solve the traffic congestion problems facing humanity and will fundamentally solve the safety of cars. problem.

Breakthrough: Automotive intelligence requires technological breakthroughs

Deng Weiwen pointed out that the "green" and "intelligent" of cars are complementary and develop together. Green cars are marked by low and zero emissions, and some or all are driven by electric motors. The result is the electrification of cars. The electrification of automobiles has entered various automobile systems. This trend will be further accelerated and will bring about revolutionary changes in the automobile industry. The arrival of the era of automotive electrification has laid the necessary technical foundation for the development of automotive intelligence. The transition from traditional cars to smart cars requires breakthroughs in many technologies. The realization of smart cars must be premised on many high-end cutting-edge technologies, such as positioning the car through GPS and indicating the driving route, using various visual and ultrasonic sensors to accurately detect pedestrians or obstacles around, and using wireless communication to determine the relationship between the car and other transportation facilities. In the end, it is necessary to make judgments through artificial intelligence and automatically execute various commands such as steering, acceleration, and parking.

Deng Weiwen said that the smart car electronic electrification system will become more and more complicated, the charge load it bears will also increase, and the power supply system will face a comprehensive upgrade. According to reports, the 14-volt power system currently used in automobiles began in the 1950s. At that time, there were fewer electronic accessories in the car, and the 14-volt power system could fully meet the needs. With the wide application of various electronic devices in automobiles, the power consumption of automotive electrical systems has increased, and the power of about 3 kilowatts in 14-volt power systems has been unable to meet the needs. Therefore, it will be the general trend to replace the 14-volt power systems with new 42-volt power systems. .

Vehicle-mounted sensor technology is another key technology of automobile intelligence. According to Deng Weiwen, the functions of on-board sensors are to detect and find targets, determine distance and bearing, identify and determine target attributes, one-dimensional and multi-dimensional imaging, and dynamic positioning and positioning tracking. Commonly used vehicle-mounted sensor technologies include microwave radar and ultrasonic photography, but each sensor technology has its limitations. Therefore, the key of sensor technology is multi-modal fusion, which not only exerts its own advantages but also provides complementary functions.

Preparation: Accelerate the development of the automotive electronics industry to prepare for intelligence

Although the "Internet of Vehicles" is still only at the conceptual stage, more and more car companies are beginning to try to apply intelligent technology to cars. Since 2009, Shanghai General Motors has launched Anjixing Onstar in-vehicle service, providing users with 11 services such as automatic collision rescue, full-range audio-controlled navigation, and stolen vehicle tracking. Initial try. Independent brands are not far behind in the research of automobile intelligence. At this year ’s Beijing Auto Show (Weibo), the “Internet Car” Roewe 350 launched by SAIC Group is equipped with the intelligent network driving system InkaNet and relies on China Unicom ’s WCDMA3G network to realize information retrieval, real-time traffic navigation, electronic road books, stock trading and Connected applications such as community communication.

As automotive intelligence is closely related to automotive electronics, the development of the automotive electronics industry will directly determine the level of automotive intelligence. However, compared with the rapidly developing automotive industry, China's automotive electronics industry is relatively lagging behind, which has become a shortcoming that restricts China's automotive industry from participating in international competition. Cheng Chuanhai, executive chairman of Changchun Qiming Information Technology Co., Ltd., believes that the overall strength of China's automotive electronics is still very weak, and the level of automotive electronic products is about 10 years behind the international advanced level. Domestic automotive electronics are in the enterprise scale, independent innovation, technology There are still gaps in levels and market development.

Relevant experts in the industry believe that in the process of promoting the development of the automotive industry, the automotive electronics industry should be highly valued, and it is recommended that by establishing an industry-university-research cooperation system, creating an electronic industry technology platform, promoting the clustering development of the electronics industry, and formulating preferential policies for the electronics industry And a series of measures to improve the competitiveness of China's automotive electronics industry and lay a solid foundation for the future realization of automotive intelligence.
