The invention discloses an electric vehicle driving control method and device and an electric vehicle. The speed control stability of the vehicle can be improved. The electric vehicle running control method comprises the steps that the total torque required by a vehicle is obtained based on the vehicle actual rotating speed and the vehicle target rotating speed; a first actual torque value of a front wheel motor and a second actual torque value of a rear wheel motor during starting control are obtained; based on the actual load ratio of the front wheel and the rear wheel, the torque distribution proportion of the front wheel and the rear wheel is determined; determining anti-skid compensation values of the front wheel and the rear wheel based on the speed difference of the front wheel and the rear wheel; determining output limit values of a front wheel motor and a rear wheel motor based on a preset torque limit value of the vehicle; according to the total torque required by the vehicle, the first actual torque value, the second actual torque value, the torque distribution proportion of the front wheel and the rear wheel, the anti-skid compensation values of the front wheel and the rear wheel and the output limit values of the front wheel motor and the rear wheel motor, the front wheel motor is controlled to output the first torque value, and the rear wheel motor is controlled to output the second torque value.
