Abstract: As the most important component system in vehicle active safety, vehicle braking device is directly related to the safety of people and property inside and outside the vehicle, which is embodied in the performance and reliability of the vehicle braking system. In order to clarify the various factors affecting vehicle braking and the clarify methods to improve vehicle braking performance, this paper analyzes vehicle braking performance through three evaluation indexes of vehicle braking efficiency, constancy and stability, and makes a comparative study of braking test data under various roads, and expounds the key points of improving braking performance and the application of electronic control system in vehicle braking, so as to improve vehicle braking performance and reduce road safety accidents rate.
