The embodiment of the invention is suitable for the technical field of vehicles, and provides a driving mode switching method and device and a vehicle. The method comprises the steps that when the vehicle is switched from a motor driving mode to an engine driving mode, first target torque needing to be output by an engine is determined; in the adjustment process of adjusting the motor torque of the motor to the first target torque, determining the rotation speed fluctuation of the motor after the motor torque is adjusted each time; the torque difference between the first target torque and the second target torque is smaller than a preset torque difference; according to the rotation speed fluctuation, determining the torque variation when the motor torque is adjusted next time until the adjustment process is completed; and the torque of the engine is increased to the first target torque, and the motor is controlled to stop running. By adopting the method, the driving mode of the vehicle can be stably switched from the motor driving mode to the engine driving mode.

    本申请实施例适用于车辆技术领域,提供了一种驱动模式切换方法、装置及车辆,该方法包括:在车辆由电机驱动模式切换至发动机驱动模式时,确定发动机所需输出的第一目标扭矩;在调整电机的电机扭矩至第一目标扭矩的调整过程中,确定在每次调整电机扭矩后电机的转速波动;第一目标扭矩与第二目标扭矩之间的扭矩差小于预设扭矩差;根据转速波动,确定下一次调整电机扭矩时的扭矩变化量,直至调整过程完成;增加发动机的扭矩至第一目标扭矩,并控制电机停止运行。采用上述方法可以使车辆的驱动模式平稳地由电机驱动模式切换至发动机驱动模式。
