CONTROL DEVICE, SUSPENSION SYSTEM

A control device 100 according to the present invention uses the angular velocity of rotational movement, in a forward-backward direction, of an unsprung weight of a two-wheeled vehicle, said velocity being generated by the vertical directional velocity of a front wheel and the vertical directional velocity of a rear wheel being different, so as to control the damping force of a damping device that dampens force generated between a vehicle body of the two-wheeled vehicle and the front wheel and/or the rear wheel.
