摘　　要：文章介绍了电子驻车制动(EPB)系统的组成和工作原理,运用硬件在环测试对EPB电控单元控制策略进行验证,能降低实车测试的风险。基于dSPACE平台,分别从硬件台架的开发与试验软件的设计两个方面进行说明,其中硬件方面包括坡道驱动模块、坡道保护模块、开关模块;软件方面包括I/O接口模型、步进电机控制模型、ControlDesk试验管理界面。通过对不同工况下的EPB控制功能进行仿真测试,实验结果不仅证明了EPB硬件在环试验方法的有效性,也同步验证了EPB硬件在环试验平台的有效性。This paper introduces the composition and working principle of electronic parking brake system,using hardware-in-the-loop test to verify the control strategy of EPB controller,which can reduce the risk from real vehicle test.The development of hardware platform and design of test software are described respectively based on dSPACE platform.The hardware includes the driving module of ramp,the protection module of ramp,the switch module and angle feedback module;the software includes I/O interface module,the control model of stepper motor and ControlDesk test management interface.Through different conditions of EPB hardware in the loop test,the testing results not only prove the validity of EPB hardware in the loop test method,but also verify the validity of EPB hardware in the loop test platform.
