Abstract
Systems and methods are described for controlling vehicle steering. A target yaw rate and a target side-slip angle are determined for the vehicle and an initial steering angle setting is determined based on a position of a steering wheel operated by a driver of the vehicle. A nonlinear vehicle model is applied to calculate a compensated steering angle setting based on the initial steering angle setting, an actual yaw rate of the vehicle, and an actual side-slip angle of the vehicle. A steering system of the vehicle is then controls the angle of the front wheels of the vehicle based on the compensated steering angle and, by doing so, causes both the actual yaw rate and the actual side-slip angle to approach the target yaw rate and the target side-slip angle, respectively.
