Abstract
A steering apparatus for a vehicle, which can reduce the steering load and allows accurate steering angle control, is provided. In the steering apparatus for a vehicle, an estimation unit estimates a mechanical impedance upon a driver's steering manipulation. A control unit controls the steering reaction force of a steering wheel based on the estimated mechanical impedance.
