英文摘要：

Vehicle detection has some essential meanings to guarantee traffic safety, protect the environment, enhance transport capacity and decrease production cost. According to the rapid development of vehicle industry and the correlative regulations, as well as the situations of the vehicle detection device in our country, the study on detection system of vehicle braking performance has been paid more attentions. The configuration and working principle of the reaction drum braking performance test rig are introduced in this article. Using the computer control technology, thee design scheme of the system is put forward, the design of the hardware and software and the debugging of the system are discussed in detail.
