Abstract
Provided is a vehicular suspension device that achieves both of improvement in driving stability and improvement in vehicle movement performance. The vehicular suspension device includes a suspension capable of adjusting a roll center height by control of an actuator, and a roll center controller. The controller includes a traveling state corresponding height determination unit configured to determine the roll center height of the suspension in accordance with a predetermined rule on the basis of vehicle speed information and road surface information, and an actuator controller configured to control the actuator so that the roll center height reaches the roll center height determined by the unit.
Claims6
