VEHICLE STABILIZER SYSTEM

摘要

A stabilizer system for a vehicle which includes a stabilizer bar and an actuator for changing stiffness of the stabilizer bar, an electric current to be supplied to an electric motor that is a drive source of the actuator is changed based on various parameters. In detail, the supply current is made smaller (S3, S5) in a situation in which an operational direction of the actuator is toward a neutral position, than in other situation. Further, the supply current is made smaller (S6) with an increase in a distance of the operational position of the actuator from the neutral position. Moreover, the supply current is made larger (S7) with an increase in a steering speed. In detail, where the supply current is determined by multiplying a basic supply current by a control gain, the control gain is set to change depending upon the above-indicated parameter, whereby the supply current is changed based on the parameters.
