The invention relates to the technical field of motors, and discloses a control method and a device for a vehicle dual-motor driving system, a vehicle and a storage medium. The method comprises the steps that the first efficiency and the second efficiency of the dual-motor driving system are calculated in real time; wherein the dual-motor driving system comprises a first motor and a second motor,the first efficiency is the efficiency of the dual-motor driving system when the first motor is in a non-working state and the second motor is in a working state, the second efficiency is the efficiency of the dual-motor driving system when the first motor and the second motor are both in a working state; when the first efficiency is greater than the second efficiency, controlling the first motorto stop working, and controlling the second motor to work; and when the first efficiency is smaller than or equal to the second efficiency, controlling the first motor and the second motor to work. According to the invention, the efficiency maximization of the dual-motor driving system is realized, and the energy waste is reduced.

    本发明涉及电机技术领域,公开了一种车辆的双电机驱动系统的控制方法、装置、汽车及存储介质,该方法包括:实时计算双电机驱动系统的第一效率和第二效率;其中,双电机驱动系统包括第一电机和第二电机;第一效率为在第一电机处于非工作状态,且第二电机处于工作状态时,双电机驱动系统的效率;第二效率为在第一电机和第二电机均处于工作状态时,双电机驱动系统的效率;当第一效率大于第二效率时,控制第一电机停止工作,并控制第二电机工作;当第一效率小于或等于第二效率时,控制第一电机和第二电机工作。本发明实现了双电机驱动系统的效率最大化,减少了能量的浪费。
