Method and apparatus for controlling lateral stability of vehicle

A method of controlling lateral stability of a vehicle, the method stabilizing behavior of the vehicle when a lateral disturbance occurs, comprising:

• (a) a lateral disturbance detection step of detecting a lateral disturbance;
• (b) a target yaw rate computation step of calculating a driver's steering angle when the lateral disturbance is detected, and calculating a target yaw rate using the calculated driver's steering angle, and vehicle information, including vehicle behavior information and vehicle specification information;
• and
• (c) a vehicle yaw rate control step of controlling a vehicle yaw rate so as to attenuate a turning moment attributable to the lateral disturbance, thereby causing the controlled vehicle yaw rate to converge on the calculated target yaw rate.

An apparatus for controlling lateral stability of a vehicle, the apparatus stabilizing behavior of the vehicle when a lateral disturbance occurs, comprising:

• a lateral disturbance detection unit for detecting a lateral disturbance, wherein the lateral disturbance detection unit detects the lateral disturbance using a yaw rate sensor;
• a target yaw rate computation unit for calculating a driver's steering angle when the lateral disturbance is detected using a steering angle sensor;
• and
• a vehicle yaw rate control unit for controlling a vehicle yaw rate so as to attenuate a turning moment attributable to the lateral disturbance.
