ABSTRACT:
A stabilizer system for a vehicle includes a stabilizer bar and an actuator and that executes a control actively changing stiffness of the stabilizer bar in accordance with roll moment acting on a body of the vehicle. Each of a situation in which the vehicle is running straightforward and a situation in which a torque generating direction of a motor of the actuator changes in opposite direction plural times is identified as a specific situation. In the specific situation, a control of changing an operation mode of the motor such that presence or absence of occurrence of resistance of the actuator against its operation by external input force is changeable, and a control of limiting a supply current to the motor such that the torque generating direction of the motor is inhibited from coinciding with a direction away from a neutral position are executed.
