The invention discloses a dual-motor torque output control method and system and a dual-motor electric vehicle. The dual-motor torque output control method is applied to the dual-motor electric vehicle, the required torque corresponding to the current vehicle speed is determined according to the current accelerator pedal opening degree of the dual-motor electric vehicle, and whether the first motor rated output torque with a first motor as an execution motor can meet the torque output of the required torque or not is judged; whether the sum of the rated output torque of the first motor and the rated output torque of the second motor taking the second motor as an execution motor can meet the torque output result of the required torque or not is judged, torque distribution is reasonably conducted, the dual-motor torque output of the dual-motor electric automobile is determined, the required power of the whole automobile is minimum, energy consumption is optimal, and meanwhile, energy consumption is reduced. The torque distribution strategy is simple, and the torque response time is short.

    本发明公开了一种双电机扭矩输出控制方法、系统及双电机电动汽车。该双电机扭矩输出控制方法应用于双电机电动汽车,根据双电机电动汽车的当前油门踏板开度确定当前车速对应的需求扭矩,通过判定以第一电机为执行电机的第一电机额定输出扭矩是否能够满足需求扭矩的扭矩输出,进而判断第一电机额定输出扭矩与以第二电机为执行电机的第二电机额定输出扭矩之和是否能够满足需求扭矩的扭矩输出的结果,合理进行扭矩分配确定双电机电动汽车的双电机扭矩输出,使整车需求功率最小,从而能耗最优,同时,扭矩分配策略简单,扭矩响应时间快。
