Vehicle control method and device and vehicle

The invention relates to a vehicle control method and device and a vehicle. The invention provides a novel single-pedal control method. The method comprises the steps that whether the current state of a motor of the vehicle is switched or not is determined according to the depth of a pedal of the vehicle, the depth change rate and the current first demand torque of the vehicle, the first demand torque is the demand torque of the vehicle in the current state of the motor, and the pedal is an accelerator pedal of the vehicle in a single-pedal mode; under the condition that the current state of the motor of the vehicle is not switched, the motor is controlled to output the first demand torque so as to control the running state of the vehicle; and under the condition that the current state of the motor of the vehicle is switched, according to the depth of the pedal of the vehicle and the current vehicle speed of the vehicle, a second demand torque of the vehicle in the state after the motor is switched is determi
