The invention discloses a dual-motor torque control method and a vehicle. The dual-motor torque control method comprises the steps that it is determined that both a first motor and a second motor complete high-voltage detection; performing fault detection on the first motor and the second motor, and determining the fault level of the first motor and the fault level of the second motor; and determining the target output torque of the first motor and/or the second motor according to the fault grade of the first motor and the fault grade of the second motor and a preset torque distribution strategy. According to the dual-motor torque control method, the energy utilization rate of the driving system can be improved, the possibility that the vehicle breaks down to stop is greatly reduced, and the reliability and economical efficiency of the vehicle are improved.

    本发明公开了一种双电机扭矩控制方法和车辆,双电机扭矩控制方法包括:确定第一电机和第二电机均完成高压检测;对第一电机和第二电机进行故障检测,确定第一电机的故障等级和第二电机的故障等级;根据第一电机的故障等级和第二电机的故障等级,按照预设扭矩分配策略确定第一电机和/或第二电机的目标输出扭矩。本发明的双电机扭矩控制方法,能提高驱动系统的能量利用率,大大降低车辆抛锚停驶的可能性,提高车辆的可靠性、经济性。
