A tailgate damping system for controlling movement of a tailgate assembly of a vehicle includes a speed sensor that provides rotational speed information of the tailgate assembly. A controller receives the rotational speed information from the speed sensor. A damping control assembly receives a tailgate shaft of the tailgate assembly. The damping control assembly includes a housing comprising a rotor chamber including a rotor member located therein. The rotor member is connected to a rotor shaft that is coupled to the tailgate shaft. A valve chamber includes a control valve located therein. The controller closes the control valve to inhibit exit of a damping fluid from the rotor chamber based on the speed information received from the speed sensor.
