【摘要】 针对集成式电子驻车制动系统,在Matlab/Simulink环境下建立了包括直流电动机、丝杠螺母以及原件内部相关的粘性摩擦和库伦摩擦等内部摩擦分析的仿真模型。为了降低使用成本,提出通过开关控制器来控制EPB系统的方法,并通过仿真与试验对比,验证了仿真模型及开关控制器在电子驻车制动系统应用的可行性。更多还原

【Abstract】 The simulation models of electrical parking brake(EPB) actuator in Simulink software were built,including DC motor model,lead-screw model and inner friction analysis models.The inner friction concluded viscous friction,Coulomb-friction and etc.In order to save cost,a method for controlling EPB system by using on-off controller was proposed.The simulation results and experiment results were compared to verify the feasibility of the proposed simulation model and on-off controller used in EPB system.更多还原
