摘　　要：针对三轴及三轴以上的多轴货车、并装双轴、并装三轴的挂车,由于并装轴的结构因素,中间轴有被相邻车轴架空的情形,导致部分轴在空载状态时测得的轴荷比实际轴荷偏小,从而使测得的轴制动率存在"虚高"情况,不能准确反映车辆加载运行状态下的制动性能。依据国家标准要求,研制机动车加载制动检测系统,对测控系统的结构、信号规范、信号调理电路、检测流程等进行详细设计与实现。实际试车表明,该系统稳定可靠,能较好地发现车辆制动隐患,提高车辆在实际载货过程中的行车安全性。The axle load measured in no?load state is lighter than the practical axle load and the measured axle brake rate is high because the middle axle may be lifted by the neighboring axle,which can′t reflect the brake performance of vehicle while loading.Following the National Standard,the loaded brake detection system of motor vehicle was developed.The structure,signal specification,signal processing circuit and detection procedure of the measurement system were designed and implemented.The practical application result indicates that the system is stable and reliable,can find the hidden dangers for vehicle brake,and improve the road safety of the vehicle in actual loading process.
