摘　　要：根据液驱混合动力车辆的特点,提出了一种集成驱动和制动控制的纵向运动控制策略。建立了基于模糊PTD控制策略的驱动、制动控制器,并结合将驱动时的滑转率和制动时的滑移率统一处理的设想,设计了车辆的纵向运动控制策略,并利用MATLAB/Simulink工具进行仿真。仿真结果表明:该策略具有响应速度快,将滑移率和滑转率控制在-0.2到0.2安全范围内的特点,可以较好地满足车辆的行驶要求。In view of the characteristics of the hydraulic gybrid vehicle （HHV）, a longitudinal motional control strategy is studied to integrate drive and braking control. A drive and braking controller using adaptive fuzzy-PID strategy is established. The union of slip and skid is discussed and implemented using union formula. Based on them, an improved longitudinal motional integrated control strategy is proposed. The strategy and the HHV model are embedded into MATLAB/Simulink to facilitate its evaluation. The simulation results indicate that the longitudinal motional integrated controller is featured with fast response to the driver speed command and varying tire slip and skid in ideal range - 0.2 - 0.2.
