The embodiment of the invention provides a gear shifting control method and device and a vehicle. The method comprises the steps that parallel control is conducted on a motor and a shifting fork in case of detecting that the difference value between the rotating speed of the motor and the target rotating speed meets a first preset range, and the parallel control comprises the steps that the shifting fork is controlled to execute pre-synchronization operation, and the motor is controlled to synchronously execute speed regulation operation; under the condition that the difference value between the rotating speed of the motor and the target rotating speed meets a second preset range, the motor torque of the motor is adjusted to zero; and under the conditions that the shifting fork completes the pre-synchronization operation and the torque of the motor is zero, a gear advancing action is executed. According to the gear shifting control method, due to the fact that motor speed regulation and shifting fork movement are conducted in parallel, the gear shifting time can be effectively shortened in comparison with the mode that in the prior art, shifting fork gear shifting operation is conducted after motor speed regulation is completed.
本发明实施例提供了一种换挡控制方法、装置及车辆,方法包括:在检测到电机的转速与所述目标转速的差值满足第一预设范围的情况下,对所述电机以及拨叉进行并行控制,其中,所述并行控制包括:控制所述拨叉执行预同步操作,且,控制所述电机同步执行调速操作;在所述电机的转速与所述目标转速的差值满足第二预设范围的情况下,将所述电机的电机扭矩调整至零;在所述拨叉完成所述预同步操作,且所述电机扭矩为零的情况下,执行进挡动作。本发明实施例所述的换挡控制方法因为电机调速和拨叉移动是并行进行的,因此相较于现有技术中电机调速完成后再执行拨叉换挡的操作,能有效缩短换挡时间。
