PURPOSE:To eliminate feeling of insufficient responsiveness of steering or lack of steering reaction for a high frequency steering input without deteriorating sound vibration performance by increasing an additional steering quantity of a steering wheel by an auxiliary steering angle only in a predetermined high frequency range of steering frequency. CONSTITUTION:A front wheel steering angle controlling device controls of an additional steering angle of a steering wheel by an auxiliary steering angle when the steering angle is given to the steering angle (a) by steering operation. In this case, a steering angle detecting means (b) is provided to detect the steering angle, and its output is inputted to a steering frequency calculating means (c). The steering frequency is calculated by a time change in steering, and when the steering angle is given to the steering wheel (a) by a fast steering operation, a control to increase an additional steering quantity of the steering wheel (a) is performed by a front steering angle control means (d) only in a predetermined high frequency range for the steering frequency. Characteristics flattened for the whole frequency range can thus be obtained. |
