Abstract
A stabilizer system for a vehicle that 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. The supply current is made smaller in a situation in which an operational direction of the actuator is toward a neutral position, than in another situation. Further, the supply current is made smaller with an increase in a distance of the operational position of the actuator from the neutral position. Moreover, the supply current is made larger with an increase in a steering speed. In detail, when 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.
