摘　　要：为了提高重载工况的适应能力,设计了一种通过液压复合制动方式进行控制的轮毂电机电动汽车。根据液压制动系统运行原理设计了更优的控制结构,为液压系统与再生制动系统构建了仿真模型,设计了可以满足复合制动需求的协调控制方案。据电机转速参数计算得到轮毂电机可以获得的最高再生制动力矩,再将其与目标制动力矩实施对比,按照实际控制策略设置相应的制动模式,将制动信号发送至制动执行部件中,实现对车辆进行制动的效果。研究结果表明:处于轻度制动状态下,采用协调控制方案时,处于前期再生制动过程中系统可以为车辆制动过程提供所需的目标制动力矩,能够满足制动性能要求。In order to improve the adaptability of heavy load conditions,a hub-motor electric vehicle controlled by hydraulic compound braking was designed.According to the operating principle of the hydraulic braking system,a better control structure is designed,a simulation model is built for the hydraulic system and the regenerative braking system,and a coordinated control scheme is designed to meet the requirements of compound brakingThe maximum regenerative braking torque that can be obtained by the wheel motor is calculated according to the motor speed parameters,and then compared with the target braking torque,the corresponding braking mode is set according to the actual control strategy,and the braking signal is sent to the braking actuator to achieve the braking effect on the vehicle.The results show that the system can provide the required target braking torque for the vehicle braking process in the early stage of regenerative braking when the coordinated control scheme is adopted in the mild braking state,which can meet the requirements of braking performance.
