Braking system performance is one of the most important properties to characterize automobile performance.The quality of braking performance directly affects the safety of the car and plays a decisive role in driving safety.However,the core part of braking performance is electronic automatic control,and the performance of automatic control system depends on the verification and calibration of a variety of complex road surfaces.In this paper,the performance test items of the chassis automation control system are summarized and analyzed through the test verification analysis and research of real vehicle cases on low-adhesion road surface,and the research results are of great reference significance for improving the design of automobile chassis automation control system.
