Vehicle control method and device and storage medium

The invention provides a vehicle control method and device and a storage medium, and relates to the field of power control. The method comprises the steps that under the conditions that the running speed of the vehicle exceeds a speed threshold value and the output torque of a first motor of the vehicle is within a preset range, torque transfer control is conducted, so that a second motor provides power for the vehicle; determining a to-be-adjusted target rotating speed of the first motor according to the rotating speed of the second motor; the working torque of the first motor is adjusted according to the first deviation between the actual rotating speed of the first motor and the to-be-adjusted target rotating speed, so that the actual rotating speed of the first motor is matched with the to-be-adjusted target rotating speed; and according to the second deviation between the target position and the actual position of the synchronizer coupling to be controlled, the synchronizer coupling is controlled, so tha
