The invention discloses a vehicle torque control method and device, a storage medium and a vehicle. The method comprises the steps that torque demand information and vehicle state information of a target vehicle are obtained, the torque demand information comprises a target torque condition and current period demand torque, the current period demand torque is used for controlling a motor to conduct torque output in the current period, and the vehicle state information at least comprises a load signal and a slope signal; determining a torque gradient model of the target vehicle based on the vehicle state information; and performing torque adjustment of at least one period on the demand torque of the current period by using the torque gradient model until the demand torque of the current period meets the target torque condition. By means of the technical scheme, it is ensured that the vehicle torque is adjusted to the target torque within a limited period, negative influences on vehicle stability and energy efficiency caused by sudden torque changes when the torque is adjusted at a time are avoided, and the running stability and comfort of the torque vehicle are ensured.

    本发明公开了一种车辆扭矩控制方法、装置、储存介质、车辆。其中,该方法包括:获取目标车辆的扭矩需求信息和车辆状态信息,其中,扭矩需求信息包括目标扭矩条件和当前周期需求扭矩,其中,当前周期需求扭矩用于控制电机在当前周期进行扭矩输出,车辆状态信息至少包括载重信号和坡度信号;基于车辆状态信息,确定目标车辆的扭矩梯度模型;利用扭矩梯度模型,对当前周期需求扭矩进行至少一个周期的扭矩调节,直至当前周期需求扭矩符合目标扭矩条件。应用本申请的技术方案,确保车辆在有限个周期内将车辆扭矩调整至目标扭矩,避免一次将扭矩进行调整时突然的扭矩变化对车辆平稳性和能源效率产生负面影响,确保扭矩车辆行驶的稳定性和舒适性。
