1. A control device comprising:
a calculation unit configured to calculate an amount of contraction of a spring of a suspension arranged between a vehicle main body and a wheel;
a derivation unit configured to derive a weight loaded on the vehicle main body by using the amount of contraction calculated by the calculation unit;
a control unit configured to control to change a damping force of the suspension, according to the weight derived by the derivation unit; and
a filter configured to smooth an output value of a stroke sensor configured to detect a stroke amount of the suspension,
wherein the calculation unit is configured to calculate the amount of contraction by using a stroke amount of the suspension during traveling of a vehicle, which has been smoothed by the filter.
