Abstract
An apparatus for controlling a stabilizer bar including: a steering angular velocity detection unit configured to detect a steering angular velocity of a vehicle in operation; a steering angle detection unit configured to detect a steering angle of the vehicle; and a control unit configured to determine whether the vehicle is turning, based on the steering angular velocity information and the steering angle information of the vehicle, and perform clutch coupling by driving a clutch of a stabilizer bar having the clutch applied thereto, when it is determined that the vehicle is turning. The control unit decides a clutch coupling time period in response to an instantaneous turning velocity of the vehicle, and performs the clutch coupling in response to the decided clutch coupling time period.

An apparatus for controlling a stabilizer bar, comprising:
- a steering angular velocity detection unit configured to detect a steering angular velocity of a vehicle in operation;
- a steering angle detection unit configured to detect a steering angle of the vehicle;
- and
- a control unit configured to determine whether the vehicle is turning, based on the steering angular velocity information and the steering angle information of the vehicle, and perform clutch coupling by driving a clutch of a stabilizer bar having the clutch applied thereto, when it is determined that the vehicle is turning,
- wherein:
- the control unit decides a clutch coupling time period in response to an instantaneous turning velocity of the vehicle, and performs the clutch coupling in response to the decided clutch coupling time period;
- and
- the control unit determines a road condition, and releases the clutch when the road is a flat road or an off-road, and couples the clutch when the road is an anti-phase wave road on which the vehicle alternately and regularly rolls from side to side with a wave motion, even though the vehicle travels straight.
A method for controlling a stabilizer bar, comprising:
- detecting steering angular velocity of a vehicle in operation through a steering angular velocity detection unit;
- detecting a steering angle of the vehicle through a steering angle detection unit;
- and
- determining, by a control unit, whether the vehicle is turning, based on the steering angular velocity information and the steering angle information, and performing clutch coupling by driving a clutch of a stabilizer bar having the clutch applied thereto, when it is determined that the vehicle is turning,
- wherein:
- the control unit decides a clutch coupling time period in response to an instantaneous turning velocity of the vehicle, and performs the clutch coupling in response to the decided clutch coupling time period;
- and
- in the performing of the clutch coupling,
- the control unit determines a road condition, and releases the clutch when the road is a flat road or an off-road and couples the clutch when the vehicle travels on an anti-phase wave road on which the vehicle alternately and regularly rolls from side to side with a wave motion, even though the vehicle travels straight.
