PURPOSE:To control the variative rate and quantity of a roll angle in time of turning a car around, by intensifying the spring force of a variable rate spring when a roll angle variation goes beyond the setting value, in ease of a suspension carrying a damping force variable damper and the variable rate spring. CONSTITUTION:Each of suspension systems 1 and 2 for both front and rear wheels is constituted of shock absorbers 3b, 4b inclusive of damping force variable dampers 3b, 4b, and spring force variable rate air springs 5, 6. Spring force in these air springs 5 and 6 is adjustable with solenoid valves 13 and 14 and controlled by a controller 15. That is to say, each of first and second weighted mean values thetam and thetan to be found from a steering angle signal Stheta out of a steering detector 16 is compared with the exciting steering angle theta, and when a difference between theta and thetam or a difference between theta and thetan is larger than the setting value, solenoid valves 13 and 14 or solenoids 7 and 8 are driven whereby spring force in these air springs 5 and 6 or damping force in dampers 3b and 4b is controlled so as to be intensified. |
