The invention provides an electric drive control system and method, an electric drive system, a vehicle and a device, and relates to the technical field of vehicles. The electric drive control system comprises an inverter, a first switch, a second switch and a third switch, the inverter comprises a first three-phase full-bridge inverter circuit and a second three-phase full-bridge inverter circuit, and the motor comprises a first winding and a second winding. Based on the motor with the first winding and the second winding, different connection modes among different windings of the motor can be realized by controlling the working modes of the first switch, the second switch, the third switch, the first three-phase full-bridge inverter circuit and the second three-phase full-bridge inverter circuit; the electric drive control system can automatically adjust the connection mode of the motor winding by controlling corresponding parts under different working conditions of the vehicle, so that the high-efficiency and low-cost vehicle electric drive control system is realized under the condition of not depending on a complex mechanical structure, and the requirements of the vehicle on power output under different working conditions are met.

    本发明提供了一种电驱动控制系统及控制方法、电驱系统、车辆、装置,涉及车辆技术领域。该电驱动控制系统包括逆变器、第一开关、第二开关和第三开关,逆变器包括第一三相全桥逆变电路和第二三相全桥逆变电路,电机包括第一绕组和第二绕组。本发明基于具有第一绕组和第二绕组的电机,通过控制第一开关、第二开关、第三开关、第一三相全桥逆变电路和第二三相全桥逆变电路的工作模式,即可实现电机不同绕组之间的不同连接方式,便于电驱动控制系统在车辆不同工况下通过控制相应部件,以对电机绕组的连接方式进行自动调节,从而在不依赖复杂机械结构的情况下,实现高效率、低成本的车辆电驱动控制系统,以满足车辆在不同工况下对动力输出的要求。
