The invention discloses an automobile output power control method, device and equipment and a storage medium, and the method comprises the steps: obtaining the maximum allowable output power of a power battery, the maximum allowable output power of an engine and the maximum allowable output power when the acceleration of a system is maximum; and the maximum allowable output power of the system is determined according to the maximum allowable output power of the power battery, the maximum allowable output power of the engine and the maximum allowable output power when the acceleration of the system is maximum, and the vehicle is controlled according to the maximum allowable output power of the system. When the total power of the system in the parallel connection stage is calculated, the maximum allowable output power of the power battery and the engine is considered, and the maximum allowable output power of the system is determined in combination with the maximum allowable output power when the acceleration of the system is maximum, so that the output power of the power battery can be ensured to be continuously reduced; the power of the power battery is prevented from being reduced too fast, and the effects that the acceleration is large enough in the acceleration process and continuous acceleration smoothness is good can be achieved.

    本发明公开了一种汽车输出功率控制方法、装置、设备及存储介质,该方法包括:获取动力电池最大允许输出功率、发动机最大允许输出功率和系统加速度最大时的最大允许输出功率,根据动力电池最大允许输出功率、发动机最大允许输出功率和系统加速度最大时的最大允许输出功率确定系统最大允许输出功率,根据系统最大允许输出功率对车辆进行控制。由于本发明中在计算并联阶段的系统总功率时,在考虑动力电池和发动机的最大允许输出功率的同时,结合系统加速度最大时的最大允许输出功率确定系统最大允许输出功率,从而可以保证动力电池输出功率持续下降,避免了动力电池功率过快降低,可以达到加速过程加速度足够大,且持续加速平顺性好的效果。
