Abstract
An apparatus for controlling a rear wheel steering includes a sensor configured to detect a vehicle speed, a steering angle, yaw rate, and a lateral acceleration of a vehicle; a target yaw rate calculator configured to determine a target yaw rate from information detected by the sensor; a side slip angle estimator configured to estimate a side slip angle from information detected by the sensor; and a rear wheel steering angle control amount calculator configured to determine a rear wheel steering angle control amount by using the yaw rate information detected by the sensor, the target yaw rate calculated by the target yaw rate calculator, and the side slip angle estimated by the side slip angle estimator. The determined rear wheel steering angle control amount is implemented to control the vehicle yaw rate to follow the target yaw rate and the side slip angle to follow 0.
