The invention relates to the technical field of electric driving of electric vehicles, in particular to an electric driving system control method, an electric driving system and a vehicle. After the whole vehicle is powered on, target torque is obtained; if the target torque is smaller than or equal to the set multiple of the peak torque of the single-winding motor, one winding of the double-winding motor is driven to work according to the target torque; otherwise, two windings of the double-winding motor are driven to work according to the target torque. High power and torque are achieved, high efficiency is achieved under the light-load working condition, the optimal efficiency of the electric drive system is achieved, and the performance of the vehicle is improved.

    本发明涉及电动汽车电驱动技术领域,具体为一种电驱动系统控制方法、电驱动系统及车辆。整车上电后,获取目标扭矩;若目标扭矩小于等于单绕组电机峰值转矩的设定倍数,则按照目标扭矩驱动双绕组电机的一个绕组工作;否则按照目标扭矩驱动双绕组电机的两个绕组工作。实现了大功率和扭矩,且在轻载工况下实现高效率,实现了电驱动系统效率最优,提高了车辆的性能。
