In a stabilizer apparatus for a vehicle, an electronic control unit
calculates a target current of an electric motor from vehicle speed,
steering angle, and lateral acceleration, and increases and decreases
actual current such that the calculated target current flows through the
motor. The control unit decreases the actual current by a predetermined
amount when the difference between the target current and the actual
current becomes smaller than a predetermined value during control of
increasing the actual current. The predetermined amount is equal to the
difference between the determined target current at the time of the
detection of the difference and current which is necessary to obtain,
during control of decreasing the actual current, an output torque equal
to the output torque of the speed reduction mechanism obtained as a
result of the target current flowing through the electric motor.
