摘要： 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.

摘要： In a suspension system for a vehicle, a suspension spring, an absorber for controllably changing the damping coefficient becoming the reference of amount of its own generating damping force, a displacement force generator for controllably generating a displacement force are arranged in parallel between sprung and unsprung members. A vibration damping control is executed based on a so-called skyhook damper theory by utilizing the displacement force. In execution of the vibration damping control, when a sign of sprung-member absolute velocity Vu and a sign of sprung/unsprung-members velocity difference ΔV are the same to each other, a damping-coefficient increasing control is executed to set a target damping coefficient C* of the absorber to a coefficient value C2 that is larger than a coefficient value C1 to which the target damping coefficient C* is set when the sign of sprung-member absolute velocity Vu and the sign of sprung/unsprung-members velocity difference ΔV are different from each other. Vibration of the sprung member can be effectively damped by cooperation of the absorber and the displacement force generator.
