The invention provides a vehicle braking energy recovery control method, device and equipment and a storage medium, the method applied to a vehicle with multiple driving motors comprises the steps that target braking force needed by the vehicle is obtained; according to the first reverse dragging braking force allowed to be provided by each driving motor, a preset braking force distribution coefficient and the current remaining electric quantity of a power battery in the vehicle, target total reverse dragging braking force allowed to be provided during braking energy recovery is determined; according to the target braking force, the target total reverse dragging braking force and the braking force distribution coefficient, second reverse dragging braking force needing to be provided by each driving motor and/or a hydraulic braking target value needing to be provided by a hydraulic braking system are/is obtained; and a motor control instruction is generated according to the second reverse dragging braking force, and/or a hydraulic control instruction is generated according to the hydraulic braking target value. The energy recovery efficiency can be improved, fluctuation of vehicle deceleration caused by switching of electric braking and hydraulic braking is effectively avoided, and the longitudinal braking effect is guaranteed.

    本申请提供了一种车辆制动能量回收的控制方法、装置、设备及存储介质,其中,应用于具有多驱动电机的车辆的方法,包括:获取车辆所需的目标制动力;根据各驱动电机允许提供的第一反拖制动力、预设的制动力分配系数以及车辆中动力电池当前的剩余电量,确定制动能量回收时允许提供的目标总反拖制动力;根据目标制动力、目标总反拖制动力以及制动力分配系数,得到各驱动电机需要提供的第二反拖制动力,和/或,液压制动系统需要提供的液压制动目标值;根据第二反拖制动力生成电机控制指令,和/或,根据液压制动目标值生成液压控制指令。本申请有利于提高能量回收效率,且,有效避免了电制动与液压制动切换导致车辆减速度的波动,保证纵向制动效果。
