The invention relates to a torque control method, device and equipment and a storage medium, and relates to the technical field of automobiles. The method comprises the following steps: switching a main vehicle control unit to a standby vehicle control unit; determining a wheel end demand torque, a wheel end actual torque and a shaft end actual torque corresponding to the vehicle; when the difference value between the wheel end demand torque and the wheel end actual torque is larger than or equal to a preset threshold value, the wheel end actual torque is adjusted to the wheel end demand torque based on a first adjustment coefficient; based on the preset distribution weight and the actual shaft end torque, the shaft end demand torque of the vehicle is determined; and adjusting the shaft end actual torque to the shaft end demand torque based on the second adjustment coefficient. Therefore, after the main vehicle control unit is switched to the standby vehicle control unit, the wheel end demanded torque can be transited to the wheel end demanded torque, and the shaft end actual torque can be transited to the shaft end demanded torque, so that the problem that the torque may suddenly change or shake when the main VCU is directly switched to the standby VCU is solved.
本申请涉及一种扭矩控制方法、装置、设备及存储介质,涉及汽车技术领域。该方法包括:将主用车辆控制单元切换至备用车辆控制单元;确定车辆对应的轮端需求扭矩、轮端实际扭矩和轴端实际扭矩;在轮端需求扭矩与轮端实际扭矩之间的差值大于或等于预设阈值时,基于第一调整系数,将轮端实际扭矩调整至轮端需求扭矩;基于预设分配权重、轴端实际扭矩,确定车辆的轴端需求扭矩;基于第二调整系数,将轴端实际扭矩调整至轴端需求扭矩。由此,可以在主用车辆控制单元切换至备用车辆控制单元后,将轮端需求扭矩过渡至轮端需求扭矩,以及将轴端实际扭矩过渡至轴端需求扭矩,解决直接将主用VCU切换至备用VCU时,扭矩可能会发生突变或者抖动的问题。
