A vehicle is controlled to perform an elastic release operation in response to a drive switching request. When unloading torque of a first electric machine of the vehicle is completed, a moving component of a disengaging and engaging apparatus of the vehicle is controlled to perform a position adaptive operation. Meshing direction and separation control is performed on the moving component when a rotational speed of the moving component reaches a stable state, to cause the moving component to move in a disengaging direction to a completely disengaged position, and switch of the vehicle from a four-wheel drive power mode to a two-wheel drive mode is completed. Speed difference of the moving component of the disengaging and engaging apparatus is effectively reduced or eliminated when the four-wheel drive power mode is switched to the two-wheel drive power mode, impact of the moving component is avoided, non-contact control or control with contact but without torque transmission is achieved for the moving component.
