Analysis of Development Trend of China Automotive Electronics Industry
December 15, 2022
Automotive electronics technology has evolved from using a single technology to solve specific problems to the stage of solving system problems with integrated and integrated control technology. The goal of integrated integrated control is to achieve a unified and coordinated control over multiple control objectives to improve overall vehicle dynamics, economy, ride comfort and stability.
For example, chassis integrated electronic control technology combines the functions of anti-lock braking system ABS, drive wheel anti-skid technology ASR, active front steering system AFS and direct yaw control DYC; integrated control of the engine and automatic transmission Integrated control of active and passive safety technologies.
In a distributed control system based on the vehicle control network <br> <br> Currently, the number of electronic control units on the car more and more, even up to dozens. In order to realize multi-objective integrated integration control, a control layer at the highest level needs to be established to play a comprehensive and coordinated role, such as the vehicle controller VECU, to obtain the best vehicle control effect through the global optimization method. The application of in-vehicle network bus technology based on automotive distributed control systems provides technical assurance for the integrated integrated control of the vehicle.
Safety control technology and intelligent automotive parts <br> <br> With the rapid development of information technology and sensor technology to accident prevention as the main purpose of intelligent safety control technology came into being. This kind of technology can automatically sense the traffic environment, judge the driving safety status of the vehicle in advance, and actively assist the driver in achieving control of the vehicle status, which greatly improves the driving safety of the vehicle.
In addition, with the rapid development of chip technology and in-vehicle network technology, and people's further improvement in vehicle comfort and handling performance, more and more auto parts have emerged with intelligent features, such as the ability to achieve turn-following functions. Intelligent lighting system, intelligent air conditioner with automatic temperature adjustment function, fully automatic smart seat with automatic memory function, intelligent parking system that can realize panoramic video, adaptive cruise assisted driving control, automatic collision avoidance control, etc.
