Abstract
The present invention provides a rear-wheel steering angle control device which is capable of drastically reducing the man-hours required for setting a gain of a target rear-wheel steering angle relative to a front-wheel steering angle. The rear-wheel steering angle control device includes a target rear-wheel steering angle calculating device which has a variable coefficient inputting device. A specific parameter (such as steady &bgr; gain) of a theoretical transfer function of physical quantity (such as vehicle-body slip angle &bgr;) relative to a front-wheel steering angle is multiplied with variable coefficients (such as K&bgr;) to a transfer function as a target transfer function (target &bgr; transfer function ).
