An Adaptive Driving Beam System Based on the Multiple Vehicle Detecting Technique

The Adaptive Driving Beam (ADB) technology ˈwhose function is to shade the high beam at the corresponding position of the opposite vehicle while the brightness of the high beam at other positions remains unchanged, has become popular in recent years. In the 21st century, the number of vehicles in various countries in the world has increased greatly, which has also led to many safety problems, in which the improper use of lamps accounts for the main part. At the same time, the technology of LED lighting and communication is advancing rapidly, which provides a guarantee for the development of intelligent lighting systems. In this article, an ADB system based on S32K148 MCU and CAN bus is designed, which can accurately identify single or multiple targets in front. This paper represents the algorithm principle, hardware and software design of the ADB system. The ADB system can improve the safety of the automobile, which plays an important role in the development of the modern automobile industry.
