摘　　要：行车制动反应时间是评价气压制动系统响应特性的重要指标,决定着行车制动的安全性。该文分析制动管路、部件布置和管路气压3个关键因素对制动反应时间的影响,基于ECE R13法规和GB 12676标准阐述商用车和挂车制动反应时间的测试方法,测试方法体现两者的不同,挂车反应时间测试需要单独额外的模拟装置。该文分别选用商用机动车(牵引汽车)和挂车相关测试样车,重点阐述气压行车制动反应时间的测试流程及注意事项,对数据处理的具体过程做详细解释。测试数据表明:商用车和挂车两测试样车的行车制动反应时间均符合ECE R13法规和GB 12676标准的要求,对进一步完善制动系统测试评价提供基础。Service brake response time is an important index of the air braking system response characteristic directly determining the safety of the service braking system. Three key factors such as braking pipe, component arrangement and pipeline pressure that influence the braking response time are analyzed. Based on ECE Regulation 13 and GB 12676 standard, the test method ofcommercial vehicles and trailer brake response time is described; the test method reflects the difference between of them, and the trailer response time test requires a separate additionalsimulation device. The article selected commercial motor vehicle （ tractor） and trailer as testprototype, focusing on the test flow and precautions of the response time of the pneumatic brakingsystem, and explains the concrete process of the data processing. The test data shows that the response time of the commercial vehicle and the trailer are in accordance with the requirements of the ECE R13 regulations and the GB 12676 standard, which provides the basis for further improving the braking system testing and evaluation.
