The invention discloses an electric vehicle sliding energy recovery control method, device and equipment and a storage medium. The method comprises the steps that whether the electric vehicle enters a sliding recovery mode or not is judged, and if yes, the vehicle deceleration of the electric vehicle is obtained; vehicle driving parameters are obtained, the motor target recovery torque of the electric vehicle is calculated through a preset logic algorithm according to the vehicle driving parameters and the vehicle deceleration, and the hydraulic braking compensation torque is calculated according to the motor target recovery torque and the motor actual recovery torque; and hydraulic braking is conducted on the electric vehicle according to the hydraulic braking compensation torque. According to the method, the deceleration of the electric automobile in the sliding energy recovery process can be only associated with the accelerator pedal opening degree operated by a driver and the automobile speed and is decoupled from factors such as automobile running parameters, motor state parameters and battery state parameters, and the accuracy and stability of the vehicle deceleration responding to user driving operation are obtained; and the driving comfort, the driving safety and the economical efficiency are improved.

    本发明公开了一种电动汽车滑行能量回收控制方法、装置、设备及存储介质。方法包括:判断电动汽车是否进入滑行回收模式,若是,获取电动汽车的车辆减速度;获取车辆行驶参数,根据车辆行驶参数与车辆减速度通过预设逻辑算法计算电动汽车的电机目标回收扭矩,根据电机目标回收扭矩与电机实际回收扭矩计算液压制动补偿扭矩;根据液压制动补偿扭矩对电动汽车实施液压制动。本申请能够实现电动汽车在滑行能量回收过程中的减速度大小仅与驾驶员操作的加速踏板开度、车速关联,与车辆行驶参数、电机状态参数、电池状态参数等因素解耦,获取车辆减速度响应用户驾驶操作的精确性和稳定性,提高驾乘舒适性、行车安全性、经济性。
