摘　　要：电子液压制动(EHB)是利用电子控制系统来实现液压执行部件的控制功能,把轮毂电机安装于轮辋中,可以控制车辆处于紧急工况时的运行稳定性.选择轮毂电机作为电液复合制动系统驱动系统,设置高压蓄能器与液压泵结合的EHB轮缸压力调控模式,利用Simulink-AMESim仿真平台完成控制策略可行性测试.研究结果表明,制动平顺性控制策略,并构建了一种通过PID矫正方式来补偿电机制动的方法.相比较其他方法,该方法可以显著降低进入电液制动切换后的冲击,进而高效率地增强制动平顺性.Electronic hydraulic braking(EHB)is the use of electronic control system to achieve the control function of hydraulic actuator parts,the hub motor installed in the rim,can control the stability of the vehicle in emergency conditions.The hub motor is selected as the driving system of the electro-hydraulic composite braking system,and the EHB cylinder pressure control mode combined with the high pressure accumulator and the hydraulic pump is set up.The feasibility test of the control strategy is completed by Simulink-AMESim simulation platform.The results show that the braking ride control strategy,and a PID correction method to compensate motor braking method is constructed.Compared with other methods,the proposed method can significantly reduce the impact after entering the electro-hydraulic braking handover,and thus efficiently enhance the braking ride comfort.
