Abstract
A front wheel steering control device improves the handling and stability of a vehicle with respect to the steering wheel angles. The front wheel steering control device includes an input device for obtaining the steering wheel angle and the vehicle velocity, a first computing device for computing a yaw-rate for the vehicle which maintains the vehicle gravity center point sideslip angle at zero based on the steering wheel angle and the vehicle velocity that are obtained by the input device, a second computing device for computing a target front wheel actual steering angle for realizing the yaw-rate calculated by the first computing device, a control device for performing a steering control of the vehicle based on the target front wheel actual steering angle calculated by the second computing device. The ideal determination of the vehicle steering gear ratio and the derivative steering gain are relatively easy.
