Abstract
A steering apparatus for a vehicle includes an operating lever, an operating amount sensor that detects the operating amount of the operating lever, an operating reaction force motor that imparts an operating reaction force to the operating lever, a steering mechanism section that steers a steered wheel of a vehicle, a rack position sensor that detects the steered amount of the steered wheel, an operating torque sensor that detects an operating torque, and a control device that determines the control amount for the operating reaction force motor and the control amount for the steering mechanism section in accordance with a deviation between the above operating amount and the above steered amount. The control device includes a feedforward control device that feedforward-controls the steering mechanism section in accordance with the operating torque, and a band-pass filter that increases or decreases the feedforward effect in accordance with the operating frequency. By adjusting the feedforward effect with the band-pass filter in accordance with the operating frequency of the operating element, the responsiveness can be adjusted.
