The growth rate of the use of automobiles has exceeded the speed of road traffic renewal and expansion, and road traffic safety has become a global topic. According to research reports, by 2020, the damage caused by transportation will become the third largest disease and injury burden in the world.
Recently, Jin Xin, deputy director of the Safety Production Department of the Ministry of Industry and Information Technology, stressed the importance of the development of automotive active safety technology at an autonomous vehicle development and testing technology conference. He pointed out that accelerating the development of smart and active safety technology as soon as possible is of great significance for solving the problem of high traffic accidents and reducing casualties. The development of electronic information technology provides a very good opportunity for the development and application of such active technologies.
In recent years, China's car ownership has grown rapidly. By the end of last year, car ownership had reached 172 million. Among them, 13.89 million trucks were used, and 14.73 million vehicles were used for road operations, including passenger vehicles. Accidents caused by traffic vehicles account for about half of all types of traffic accidents. According to the World Health Organization, the number of traffic accidents per year worldwide is 1.2 million, and the number of traffic accidents per year in China is 20,000-270,000. Such a huge number has made the government pay more and more attention to this field, and regards the development of automobile active safety technology as a major focus of industrial development.
A few days ago, at the "Automobile Active Safety ESC System Design Salon" of Murata Manufacturing Co., the editor of the automotive electronics network learned that with passive safety technology, airbag and seat belt technology are very mature. ADAS intelligent active safety is becoming a hot spot in the development of automotive safety technology, and is also a hotspot in the investment community. Among them, the application of the Electronic Stability Control (ESC) vehicle active safety is a further extension of the functions of the anti-lock braking system (ABS) and the traction control system (TCS), and on this basis, The yaw rate sensor, the direction finding acceleration sensor and the steering wheel angle sensor are added when the vehicle is turned to travel, and the driving force and the braking force of the front and rear, left and right wheels are controlled by the ECU to ensure the lateral stability of the vehicle.
The ESC invention greatly enhances vehicle safety and can significantly reduce the risk of loss of control of the vehicle on emergency steering or slippery roads. (According to the US NHTSA (Highway Traffic Safety Administration) estimates, ESC equipment has reduced 32% of car accidents and 57% of SUV bike accidents.)
At present, European and American countries have already forced the popularization of the configuration of this system, and China is also likely to formulate new regulations to minimize the death rate of traffic accidents. It is understood that Europe and the United States have taken many measures in relevant legislation and in terms of technical regulations. For example, European and American countries have forced the popularization of ESC system configuration. In addition, AEB (Automatic Emergency Brake Assist System) has also been included in the system that must be equipped by the European Union. The United States also requires major auto companies to install AEBs for vehicles entering the United States, and gradually increase the number of cars in the new car crash rating test. Assessment of active safety technology.
Jin Xin revealed that the Chinese government is also actively promoting the development and application of automotive active safety technology. China's national standards for AEB have been completed and drafting standards are expected to be released in 2017.
Jiang Junjie, a senior engineer in research and development at Murata's product department, told the auto electronics network that major auto companies have "armed their teeth to the teeth." Some passive safety technologies such as seat belts, airbags, safety steering columns and anti-collision steel beams are on the stage. Today, the concept of protection has been extended to all people and even objects inside and outside the car. The leap from passive safety to active safety can be said to be a major advance in the history of automobile development, from the current "destructive destruction of accidents" to "avoiding accidents."
The combination of automotive and electronic intelligence systems is the fundamental reason for moving from "passive" to "active." The extensive application of advanced electronics, communication and information technology has enabled the traditional automobile to move toward a new round of intelligent and interconnected automotive technology innovation, which is being carried out worldwide.
Not only the OEMs are striving to develop active safety technologies, but also Delphi and Bosch, which have advantages in automotive active safety technology, provide solutions for active safety applications for more and more OEMs.
Automotive active safety technology will become the focus of future automotive technology development. For automotive safety, active safety systems are as important as passive safety systems. The two complement each other and work together to ensure the safety of drivers, pedestrians and society. Future trends will also be the integrated control of active and passive security technologies.
