摘要： 本文中基于逻辑门限控制方法提出气压式电子驻车制动器(EPB)的坡道起步控制策略。首先,分析了气压式EPB的工作原理和车辆坡道起步的过程,建立了坡道起步过程中EPB气压控制模型,提出了坡道起步的控制目标;然后,研究了试验车的EPB电磁阀的工作特性,并提出了坡道起步中的气压式EPB逻辑门限控制方法;最后,利用Matlab/Simulink和TruckSim进行逻辑门限控制方法的联合仿真,并进行实车试验。仿真和试验结果表明,采用本文中提出的坡道起步的气压式EPB逻辑门限控制方法,车辆制动释放延迟较短,坡道起步效果更好。

Abstract: A hill start control strategy for pneumatic electronic parking brake (EPB) based on logic threshold control scheme is proposed in this paper. Firstly, the working principle and the hill-start process of EPB are analyzed, the pressure control model of EPB for hill-start is established and the control objective of hill-start is put forward. Then, the characteristics of EPB solenoid valve of tested vehicle are studied and the logic threshold control scheme of pneumatic EPB during hill start is given. Finally, both the co-simulation with Matlab/Simulink and TruckSim and real vehicle test on logic threshold control scheme are conducted. The results of simulation and test show that with the logic threshold control scheme of pneumatic EPB proposed for hill start, the release delay of vehicle braking is shortened, achieving a smoother hill start
