摘要:

\tEBS挂车阀是汽车电控制动系统的关键性控制件之一,其气压调节特性直接影响制动系统工作的稳定性。针对该阀的内部结构及工作原理,建立EBS挂车阀数学模型并基于Simulink仿真软件,实现EBS挂车阀电流迟滞特性、静态特性仿真;为验证仿真结果的准确性和可用性,设计一套以LabVIEW软件开发的EBS挂车阀检测系统,在试验台上进行挂车阀特性试验。结果表明:实际测得该阀迟滞电流为0.26 A,输出气压与控制电流、气压基本呈线性相关,仿真与测试结果基本保持一致,仿真模型准确可用。

Abstract: The EBS trailer valve is one of the key control parts of the automotive electric control braking system, and its air pressure regulating characteristics directly affect the stability of the braking system. Based on the internal structure and working principle of the valve, the mathematical model of the EBS trailer valve was set up and based on Simulink simulation software, the current hysteresis characteristic and static characteristic simulation of the EBS trailer valve are realized. In order to verify the accuracy and availability of the simulation results, a set of EBS trailer valve detection system developed by LabVIEW software was designed, and the characteristic test of the trailer valve was carried out on the test platform. The results show that the hysteresis current of the valve is actually 0.26 A, and the output pressure is linearly correlated with the control current and air pressure, the simulation and test results are basically consistent. So the simulation model is available accurately.
