Patent ID: 8050823

Claim:
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 configured to detect a lateral disturbance; a target yaw rate computation unit configured to calculate 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 wherein the target yaw rate computation unit is configured to calculate the driver's steering angle by extracting a number of steering angles equal to a number of samples, measured before a time point at which the lateral disturbance was detected, at intervals of sampling periods and calculate an average of the number of steering angles equal to the number of samples; and a vehicle yaw rate control unit configured to control 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.
