Abstract:

A research progresses on the working principle, development path, application status and regulation of the autonomous emergency braking (AEB) technology were introduced to promote the car’s autonomous emergency braking technology to be safer and more efficient. The key technologies related to the
comprehensive performance of AEB system were summarized, including collision avoidance strategy, braking execution technology and front-end perception technology. The results show that AEB system can effectively avoid or mitigate collision, which can greatly improve the vehicle's active safety performance. However, AEB system can’t avoid any collision at higher vehicle speed and more complex traffic scenarios on account of low level braking execution technology and front-end perception technology. The technology focus for AEB will be comprehensive performance optimization of collision avoidance strategy in more complex traffic scenarios, the development of brake actuators based on shorter response time objectives, and the deep integration and the coordinated control of multiple active safety technologies under dangerous driving conditions.
