The invention provides a vehicle sliding energy recovery control method, device and equipment and a storage medium. The method comprises the steps that the whole vehicle required recovery torque of a vehicle in a sliding energy recovery state is obtained; the first available recycling torque of a motor and the second available recycling torque of a battery are obtained, and the minimum value of the first recycling torque and the second recycling torque is taken as the available recycling torque of the whole vehicle; when the available recycling torque of the whole vehicle does not meet the required recycling torque of the whole vehicle, the difference value between the required recycling torque of the whole vehicle and the available recycling torque of the whole vehicle is determined to serve as hydraulic braking torque; and a hydraulic braking controller is requested to respond to the hydraulic braking torque, and a motor controller is requested to respond to the available recycling torque of the whole vehicle. That is, the coasting recovery torque distribution strategy is optimized, through combined braking of electric braking and hydraulic braking, the consistency of speed reduction during coasting feedback is kept, the expected braking effect is achieved, and the drivability during energy recovery is improved.

    本说明书提供一种车辆滑行能量回收控制方法、装置、设备及存储介质,方法包括:获取车辆在滑行能量回收状态下的整车需求回收扭矩;获取电机的第一可用回收扭矩与电池的第二可用回收扭矩,取所述第一回收扭矩与所述第二回收扭矩的最小值作为整车可用回收扭矩;当所述整车可用回收扭矩不满足所述整车需求回收扭矩时,确定所述整车需求回收扭矩与所述整车可用回收扭矩的差值作为液压制动扭矩;请求液压制动控制器响应所述液压制动扭矩,并请求电机控制器响应所述整车可用回收扭矩。也即,优化滑行回收扭矩分配策略,通过电制动与液压制动的联合制动,保持滑行回馈时减速的一致性,达到预期制动效果,提高能量回收时的驾驶性。
