The invention provides a control method of a dual-motor auxiliary driving system and a vehicle, and the control method comprises the steps that a request instruction is received, the request instruction is used for requesting to control an execution mechanism of the dual-motor auxiliary system of a target vehicle to execute a target action, and the target action comprises one of a synchronous disconnection action and a synchronous combination action; detecting a first current action of the execution mechanism, and determining whether the first current action of the execution mechanism is consistent with the target action to be executed or not; when it is determined that the first current action of the execution mechanism is inconsistent with the target action to be executed, a torque speed adjusting instruction is generated, and the torque speed adjusting instruction is used for adjusting the torque and the rotating speed of each motor in the dual-motor auxiliary system; and responding to the request instruction when determining that the torque and the rotating speed meet preset conditions based on the torque speed adjusting instruction. The operation of synchronous disconnection or synchronous combination of the double motors is realized, so that the synchronism of the double motors is improved, and the stability of the vehicle is further improved.

    本发明提供了一种双电机辅助驱动系统的控制方法及车辆,控制方法包括:接受请求指令,其中,请求指令用于请求控制目标车辆的双电机辅助系统的执行机构执行目标动作,目标动作包括同步断开动作和同步结合动作中的一个;检测执行机构的第一当前动作,确定执行机构的第一当前动作是否与待执行的目标动作一致;在确定执行机构的第一当前动作与待执行的目标动作不一致的情况下,生成扭速调节指令,其中,扭速调节指令用于调节双电机辅助系统中的各电机的扭矩和转速;基于扭速调节指令确定扭矩和转速满足预设条件的情况下,响应请求指令。实现了对双电机同步断开或同步结合的操作,以提高双电机的同步性,进而提高了车辆的稳定性。
