The invention provides a torque control method and device, electronic equipment and a vehicle, and is applied to a driving motor control unit deployed with a differential protection strategy, and the torque control method can determine a conflict type when detecting a torque control conflict; performing torque control according to an activation sequence of a jolting protection strategy and a slip rate control strategy in response to the fact that the conflict type is a jolting protection type conflict; and in response to the fact that the conflict type is a differential protection type conflict, torque arbitration is performed on the differential protection strategy and the slip rate control strategy, and torque control is performed according to the output torque after arbitration. The torque output is controlled by determining the execution sequence of different function strategies, the rushing problem occurring when the vehicle accelerates on the low-attachment road surface is solved, and the bridge can be protected while the whole vehicle slip rate is controlled without affecting the DTCS function.

    本申请提供一种扭矩控制方法、装置、电子设备及车辆,应用于部署有差速保护策略的驱动电机控制单元,扭矩控制方法能够在检测到扭矩控制冲突时,确定冲突类型;响应于冲突类型为颠簸保护类冲突,根据颠簸保护策略和滑移率控制策略的激活顺序进行扭矩控制;响应于冲突类型为差速保护类冲突,对差速保护策略和滑移率控制策略进行扭矩仲裁,并根据仲裁后输出扭矩进行扭矩控制。通过确定不同功能策略的执行顺序对扭矩输出进行控制,解决了车辆在低附路面加速时出现的闯动问题,在不影响DTCS功能控制整车滑移率的同时,可以实现对电桥的保护。
