Abstract
A damping force control apparatus includes a damping force control device controlling a damping force of a shock absorber provided between a sprung mass and an unsprung mass of each wheel of a vehicle, a detection device detecting at least an acceleration of the sprung mass in an up-down direction and a relative displacement between the sprung mass and the unsprung mass, a damping coefficient calculation device calculating a damping coefficient to be applied to the damping force control by the damping force control device based on detected results of the detection device, a sensed acceleration increment calculation device calculating a sensed acceleration increment corresponding to an increment of sense according to the Weber Fechner law on the basis of the detected results of the detection device, and a modification device modifying the damping coefficient in accordance with a sensed acceleration increment calculated by the sensed acceleration increment calculation device.
