The embodiment of the invention discloses a gear shifting speed regulation control method and device of a dual-motor driving system and a vehicle. The dual-motor driving system comprises a first motor and a second motor and is used for controlling the rotating speed of the second motor to complete gear shifting when the first motor drives the vehicle to run and the second motor shifts gears. The gear shifting speed regulation control method comprises the steps that the current running state of a vehicle is determined according to the running state of a first motor; determining a target rotating speed compensation value of the second motor according to the driving state and the target gear of the second motor; adjusting the rotating speed of the second motor according to the target rotating speed compensation value to enable the rotating speed of the second motor to be matched with the target gear. According to the technical scheme, the problem that gear shifting fails due to the fact that the difference between the real-time rotating speed of the motor and the synchronous meshing rotating speed of the motor is too large during gear shifting of the second motor can be solved, and the gear shifting stability of the second motor is improved.

    本发明实施例公开了一种双电机驱动系统的换挡调速控制方法、装置及车辆。双电机驱动系统包括第一电机和第二电机,用于在第一电机驱动车辆行驶,第二电机换挡时,控制第二电机的转速以完成换挡;换挡调速控制方法包括:根据第一电机的运行状态,确定车辆当前的行驶状态;根据行驶状态和第二电机的目标挡位,确定第二电机的目标转速补偿值;根据目标转速补偿值调整第二电机的转速,以使第二电机的转速匹配目标挡位。本发明实施例的技术方案可以解决第二电机换挡时电机的实时转速和电机同步啮合转速差异过大导致换挡失败的问题,提高第二电机的换挡稳定性。
