Method for regulating damping force of infinitely variable semi-active damper between body and chassis of motor vehicle, involves utilizing relative speed of damper piston rod for damper pipe as reference variable

摘要

The method involves utilizing a relative speed of a damper piston rod for a damper pipe or a damping force of the damper piston rod or a differential pressure of chamber pressures controlled from both sides of a damper piston in the drive chambers of a damper cylinder as a reference variable.
