Vehicle control method and device, vehicle and computer readable storage medium

The invention provides a vehicle control method and device, a vehicle and a computer readable storage medium, and relates to the technical field of vehicle control, the vehicle comprises a boost converter, a battery and a driving motor, the boost converter is connected with the battery and the driving motor, and the method comprises the steps that the target torque of the vehicle, the actual rotating speed of the motor and the voltage of the battery are obtained; determining original target voltage according to the target torque and the actual rotating speed of the motor; taking the maximum value of the original target voltage and the battery voltage as a final target voltage; and determining the operation state of the boost converter according to the final target voltage so as to boost and supply power to the driving motor through the battery and the boost converter. The method has the beneficial effects that the loss of a vehicle system can be reduced, and the power performance of vehicle operation is impro
