Car has good braking performance, meet an urgent circumstance, can hook, in normal operation, can increase the average speeds, thereby improving transportation production efficiency. In emergency need braking, can improve the safety of auto brake, and greatly reduces the probability of traffic accident. With sensing technology, microelectronics, computer software and hardware and digital signal processing technology, expert systems, fuzzy set theory etc. Comprehensive application of intelligent system and enhance the automobile braking performance testing of research methods for the automotive industry development has brought unprecedented dawn. The braking performance testing mainly includes braking force, braking force balance requirement, wheel, brake coordination time. Resistance against. This paper mainly on the brake system structure and the performance test of brake system domestically, the brake system domestically and of cognition.
