The invention relates to a torque control method, device and equipment and a storage medium, the total output torque of a vehicle is calculated through the current demand torque of the vehicle and the current driving intention coefficient of the vehicle, then motor torque control is conducted according to the total output torque, and the driving intention coefficient represents the current acceleration intention intensity of the vehicle. Therefore, the acceleration condition of the vehicle in a period of time in the future can be reflected to a certain extent, and the total output torque of the motor is calculated by combining the acceleration condition of the vehicle in the period of time in the future and the current required torque of the vehicle. And a better torque distribution scheme can be obtained, so that the output torque is balanced between the current driving demand and the future driving demand, and the user experience is improved.

    本申请涉及一种扭矩控制方法、装置、设备及存储介质,通过车辆当前的需求扭矩和车辆当前的驾驶意图系数计算车辆的输出总扭矩,然后根据输出总扭矩进行电机扭矩控制,驾驶意图系数表征了车辆当前的加速意图强度,因此可以从一定程度上反映车辆在未来一段时间内的加速情况,结合车辆在未来一段时间内的加速情况以及车辆当前的需求扭矩计算电机的输出总扭矩,相比于现有方案中仅根据车辆当前的油门踏板开度确定电机的输出扭矩而言,可以得到更优的扭矩分配方案,使输出扭矩在当前的驾驶需求和未来的驾驶需求之间得到平衡,提升了用户体验。
