摘　　要：针对分布式电驱动汽车的操纵稳定性和能量效率集成问题,提出一种分层控制策略。上层控制策略采用滑模控制理论计算期望的附加横摆力矩,基于驱动电机的MAP效率特性,下层控制策略以4个驱动电机的总能耗为优化目标,以上层控制策略得到的附加横摆力矩为约束条件,优化分配4个电机的驱/制动转矩。在Simulink/CarSim平台对其进行了有效性验证,仿真结果表明:该控制器可以在保证车辆稳定性的同时,大幅降低车辆在中低速的能耗。In this article,with the focus on the integration of handling stability and energy efficiency of distributed electric vehicles,a strategy of hierarchical control is proposed.The upper-level control strategy uses the sliding-mode control theory to calculate the expected additional yaw moment.Based on the MAP efficiency characteristics of the drive motor,the lower-level control strategy,aimed at optimizing the total energy consumption of the four drive motors,takes the additional yaw moment obtained by the upper-level control strategy as the constraints,in order to optimize the distribution of the drive/braking torque of the four motors.The validity of the controller is verified by means of the Simulink/Carsim platform.The simulation results show that the controller can greatly reduce energy consumption when the vehicle is running at the medium and low speeds,while ensuring its stability.
