Abstract:
1. A damping force control apparatus, comprising: a damping force control means 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 means 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 means calculating a damping coefficient to be applied to the damping force control by the damping force control means based on detected results of the detection means; a sensed acceleration increment calculation means 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 means, the Weber Fechner law being defined as ΔE=k*(Δz″/z″), wherein ΔE is sensed acceleration increment, k is a constant factor, z″ is physical magnitude of acceleration, and Δz″ is increment of acceleration; and a modification means modifying the damping coefficient in accordance with a sensed acceleration increment calculated by the sensed acceleration increment calculation means.
