摘　　要：半挂车作为公路长途运输的重要交通工具,其安全性能一直备受关注。目前半挂车所配备的一般为气压控制制动系统,为改善车辆制动性能,提升车辆在行驶过程中的安全性,电子控制制动系统逐步应用到半挂车上。论文详细阐述了半挂车电子控制制动系统的工作原理,与气压控制制动系统进行了对比,电子控制制动系统提高了制动安全性,同时提升了系统集成化。基于GB 12676-2014,设计半挂车电子控制制动系统响应时间测试系统,模拟装置可以满足电控线路和气控管路的测试需求。选取某半挂车进行制动系统的响应时间测量,通过试验表明电子控制制动系统可有效减少制动响应时间,加快车辆在制动时的反应,保障半挂车的行驶安全。As an important means of transportation for long-distance highway transportation,the safety performance of semi-trailer has attracted much attention.At present,the semi-trailer is generally equipped with pneumatic control braking system.In order to improve the braking performance of the vehicle and enhance the safety of the vehicle during driving,the electronic control braking system is gradually applied to the semi-trailer.In this paper,the working principle of the semi-trailer electronic control braking system is described in detail.Compared with the pneumatic control braking system,the electronic control braking system improves the braking safety and system integration.Based on GB 12676—2014,the response time test system of semi-trailer electronic control braking system is designed.The simulation device can meet the test requirements of electronic control circuit and pneumatic control pipeline.A semi-trailer is selected to measure the response time of the braking system.The test shows that the electronic control braking system can effectively reduce the braking response time,accelerate the vehicle's response during braking,and ensure the driving safety of the semi-trailer.
