Patent ID: 7744098

Claim:
A stabilizer system for a vehicle comprising: a stabilizer apparatus which includes: a stabilizer bar connected at opposite ends thereof to respective wheel holding members which respectively hold left and right wheels of the vehicle; and an actuator which changes rigidity of the stabilizer bar in accordance with an operational amount of the actuator from a neutral position; and a control device which determines a target operational amount of the actuator based on a roll-moment-index amount indicative of roll moment that acts on a body of the vehicle, wherein the stabilizer apparatus has a structure in which a deflection amount of the stabilizer bar is made different for different directions of the roll moment, and wherein the control device determines the target operational amount based on a direction of the roll moment that acts on the body of the vehicle, such that the target operational amount is made different for different directions of the roll moment that acts on the body of the vehicle and controls an operation of the actuator based on the determined target operational amount in order to reduce a difference between the rigidity of the stabilizer bar to be exhibited with respect to the roll moment in one of the different directions and the rigidity of the stabilizer bar to be exhibited with respect to the roll moment in the other of the different directions, the difference arising from the structure of the stabilizer apparatus.
