Damping force control system for automotive vehicle

摘要

A damping force control system for an automotive vehicle having a semiactive damper mechanism provided between an unsprung mass and a sprung mass of the vehicle, wherein vertical velocity of the sprung mass is detected so that switchover of the semiactive damper mechanism from a low damping state to a high damping state is permitted upon lapse of a predetermined time after it has been detected that an absolute value of the detected vertical velocity of the sprung mass exceeded a preselected magnitude of approximate zero.
