ABSTRACT:
A stabilizer system for a vehicle including: a stabilizer bar connected to left and right wheels at respective opposite ends thereof; an actuator which has an electric motor and which changes elastic force to be exhibited by the stabilizer bar, as a result of control of an operation of the electric motor; and a control device which controls the operation of the electric motor, wherein the control device includes an operation-mode changing portion which changes an operation mode of the electric motor that depends on a motor-phase-connecting formation and a power-supply status of the electric motor, on the basis of at least one of a vehicle running state and road surface condition.
