ABSTRACT:
In apparatus and method for controlling a damping force characteristic for a vehicular suspension system, a control force (F) based on an ideal Sky Hook theory is generated even when a low responsive characteristic and less expensive actuator such as a stepping motor associated with an adjuster of each shock absorber and which is not enabled to respond to an unsprung mass resonance frequency and a control signal based on a sprung mass vertical velocity and on a relative velocity between a vehicle body (sprung mass) and a road wheel assembly (unsprung mass) is formed using a signal processing circuit so that the control signal is formed in a low frequency band. The damping force characteristic of each shock absorber is controlled on the basis of the formed control signal.
