The invention provides a vehicle vertical vibration control method and device.A vehicle is driven by a hub motor, a suspension system of the vehicle adopts a magnetorheological damper, and the method comprises the following steps that the corner position of a rotor of the hub motor and the eccentricity of a stator and a rotor are obtained; calculating motor excitation of the hub motor according to the rotation angle position of the rotor and the eccentricity of the stator and the rotor; acquiring a vehicle body movement speed and a wheel movement speed of the vehicle; the damping force of the magnetorheological damper is determined according to the vehicle body movement speed and the wheel movement speed; and the hub motor is controlled through the motor excitation, and the magnetorheological damper is controlled through the damping force. Vibration of a vehicle body can be reduced, and therefore smoothness and safety of the vehicle in the running process are improved.
