The invention provides a vehicle torque control system, a vehicle torque control method and a vehicle, in the vehicle torque control system, a torque function module is responsible for calculating a torque request value, and a torque monitoring module is responsible for verifying the torque request value calculated by the torque function module to determine the rationality of the torque request value; and the torque function module requests appropriate torque output from the motor controller according to the verification result, and meanwhile, the torque function module and the torque monitoring module send counting signals to each other to confirm whether the software operation of the opposite side is abnormal or not, and requests zero torque output from the motor controller when confirming that the software operation of the opposite side is abnormal. Therefore, when any one module is abnormal, the other module can confirm the abnormal state of the other module in time and take effective torque reduction measures, so that the situation that the vehicle is dangerous due to an abnormal torque request is effectively avoided, and the driving safety of the vehicle is improved.

    本申请提供一种车辆扭矩控制系统、车辆扭矩控制方法及车辆,该车辆扭矩控制系统中,扭矩功能模块负责计算扭矩请求值,扭矩监控模块负责对扭矩功能模块计算出的扭矩请求值进行校验,以确定该扭矩请求值的合理性,扭矩功能模块根据其校验结果,向电机控制器请求合适的扭矩输出,同时,扭矩功能模块和扭矩监控模块相互发送计数信号以确认对方软件运行是否异常,并在确认对方软件运行异常时向电机控制器请求零扭矩输出。这样,在任意一个模块发生异常时,另一个模块可以及时确认对方的异常状态并采取有效的降扭措施,从而有效避免车辆因异常的扭矩请求而发生危险的情况,提升车辆的行驶安全性。
