The invention discloses an electric vehicle, an energy recovery control system thereof, a stability control method and a medium. The control system comprises a vehicle control unit, an ESP and a motorcontroller, a sliding energy feedback module, an ESP integrated stability control module and a braking energy feedback module are integrated in the vehicle control unit, the motor controller is integrated with a torque control module, and the stability control module calculates a torque feedback value when determining that instability occurs in the sliding energy recovery process and/or the braking energy recovery process of the electric vehicle according to the vehicle state, and sends the torque feedback value to the motor controller through communication connection between the ESP and themotor controller, so the torque control module only responds to the torque request of the stability control module. The control system can control discomfort caused by intervention of braking energy recovery in the sliding energy recovery process, and therefore the comfort in the energy recovery process is improved.
本发明公开了一种电动车辆及其能量回收控制系统、稳定控制方法和介质,其中,控制系统包括整车控制器、ESP和电机控制器,整车控制器中集成滑行能量回馈模块,ESP集成稳定控制模块和制动能量回馈模块,电机控制器集成扭矩控制模块,其中,稳定控制模块根据车辆状态确定电动车辆在滑行能量回收过程中和/或制动能量回收过程中出现失稳时计算扭矩回馈值,并通过ESP与电机控制器之间的通信连接将扭矩回馈值发送给电机控制器,以便扭矩控制模块仅响应稳定控制模块的扭矩请求。该控制系统可以对滑行能量回收过程中,因制动能量回收介入造成的不舒适性进行控制,从而提升能量回收过程中的舒适性。
