Title:
DAMPING FORCE CONTROL DEVICE IN SUSPENSION SYSTEM
Document Type and Number:
Japanese Patent JP3270672
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To exhibit damping force characteristics the same as specified by its target by adjusting the damping force of a damping force variable shock absorber by the use of a signal comparatively easy to be detected such as relative speeds and relative displacements above and below a spring.
SOLUTION: A damping force target value operating means 3 which sets a damping constant target value for a damping force variable shock absorber by using relative speeds and relative displacements above and below a spring as an input, is equipped with a target value setting means 15 for setting a specified constant, that is, a basic damping constant target value, and with a correction value operating means operating a clamping constant correction value out of an ideal clamping force operated based on relative speeds and relative displacements. And it is so constituted that the sum of the basic damping constant target value and the damping constant correction value shall be outputted as the damping constant target value.
