Title:
CONTROL DEVICE OF ATTENUATION FORCE VARIABLE DAMPER
Document Type and Number:
Japanese Patent JP2020075557
Kind Code:
A
Abstract:
To provide a control device of an attenuation force variable damper capable of more effectively suppressing rolling of a vehicle body.SOLUTION: A control device of an attenuation force variable damper includes: motion state quantity detection means (11-16) for detecting a motion state quantity of a vehicle 1; a roll attenuation force base setting unit 22 for setting a roll attenuation force base value DFb, which is a base value of target attenuation force of the attenuation force variable damper for roll attitude control, based on the motion state quantity; a vehicle model 23 as roll quantity calculation means for calculating a sprung roll rate ωs and an unsprung roll rate ωu of the vehicle 1 based on the motion state quantity; and a roll attenuation force correction unit 24 for correcting the roll attenuation force base value DFb based on a roll rate difference Δω which is a difference between the sprung roll rate ωs and the unsprung roll rate ωu.SELECTED DRAWING: Figure 2
