The invention belongs to the technical field of vehicles, and discloses a vehicle auxiliary braking method and device, a vehicle and a storage medium, and the vehicle auxiliary braking method comprises the following steps: judging whether a braking condition is met or not based on the position of a brake pedal, if yes, determining that the vehicle is in an engine auxiliary braking mode, namely judging whether the engine auxiliary braking condition is met or not; if the engine auxiliary braking condition is met, the whole vehicle driving power and the engine auxiliary braking power are obtained, the engine auxiliary braking power is obtained according to the whole vehicle driving power, and the process is simple; then, the maximum charging power allowed by the power battery is obtained, and the vehicle is controlled to conduct auxiliary braking, so that the driving motor is controlled to recycle braking energy, the power battery is charged, part of energy of the driving motor is recycled, and the auxiliary braking effect is achieved; in addition, according to the vehicle auxiliary braking method, a power consumption box does not need to be additionally arranged, and the structure is simple.

    本发明属于车辆技术领域,公开了车辆辅助制动方法、装置、车辆及存储介质,车辆辅助制动方法首先基于制动踏板的位置判断是否满足刹车条件,若满足刹车条件,则确定车辆处于发动机辅助制动模式,即判断是否满足发动机辅助制动条件,若满足发动机辅助制动条件,则获取整车驱动功率以及发动机辅助制动功率,其中,根据整车驱动功率获取发动机辅助制动的功率,过程简单;随后获取动力电池允许的最大充电功率并控制车辆进行辅助制动,从而控制驱动电机回收制动能量,并为动力电池充电,从而回收驱动电机的部分能量,起到辅助制动的效果;此外,该车辆辅助制动方法无需额外设置电源消耗箱,结构简单。
