The present application provides an automatic shift control method, apparatus, device and storage medium. 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. The disengaging and engaging apparatus can be disengaged without impact and noise, realizing imperceptible automatic shift control and improving driving experience of the vehicle.
