Abstract: Autonomous driving vehicles need to have the ability to automatically complete the braking action, the process of precision and comfort requirements are very high, is an important index to reflect the safety of the vehicles. In this paper, the autonomous emergency braking system of the vehicles is verified based on two braking strategies by analyzing the working characteristics of the vehicle air brake system. The results show that the point-brake baking strategy can not only improve the braking accuracy, but also improve the comfort to a certain extent, improve the safety of the vehicle and the driver and passenger, and help to further accelerate the commercialization of automatic driving.
