The application provides a vehicle gear control method, device, storage medium and equipment. In the method, when the vehicle speed is less than or equal to a preset speed threshold, a driver side door signal, a safety belt signal and an off-site sensor signal are acquired. If the door signal indicates that the door is in an open state, and the safety belt signal indicates that the safety belt is in an open state, or if the off-site sensor signal indicates that the driver is not on the seat, it is determined that the vehicle meets the automatic return to the parking gear condition. In the case that the automatic return to the parking gear function of the vehicle is in an activatable state and the vehicle meets the automatic return to the parking gear condition, the gear of the vehicle is switched to the parking gear.
