The invention discloses a vehicle output torque control method, device and system and a storage medium, and the method comprises the steps: determining the current acceleration of a vehicle when the vehicle starts a creeping mode; calculating a torque compensation value of the vehicle according to a difference value between the current acceleration and a target acceleration; the target acceleration is a test value of the vehicle in a preset road surface starting crawling mode; and adjusting the output torque in the crawling mode based on the torque compensation value. According to the scheme, the calculation process of the output torque in the vehicle crawling process is simplified, the vehicle torque is controlled based on the acceleration of the vehicle, influences of muddy and hollow road surfaces and the like are avoided, and then the accuracy of the output torque calculation result is improved.

    本申请公开了一种车辆输出扭矩控制方法、装置、系统及存储介质,所述方法包括:在车辆启动蠕行模式时,确定车辆的当前加速度;根据所述当前加速度和目标加速度的差值计算所述车辆的扭矩补偿值;所述目标加速度为所述车辆在预设路面启动蠕行模式下的测试值;基于所述扭矩补偿值调整蠕行模式下的输出扭矩。本方案简化了车辆蠕行过程中输出扭矩的计算过程,并且本申请是基于车辆的加速度对车辆扭矩进行控制,不会受泥泞、坑洼路面等影响,进而提高了输出扭矩计算结果的准确度。
