PROBLEM TO BE SOLVED: To provide a vehicle steering apparatus forgiving a stable steering behavior as a skilled person does to a vehicle while compensating for the insufficiency of the derivative action of a person. SOLUTION: In the vehicle steering apparatus which has a target steering angle ratio or a target wheel turning angle set by steering a steering wheel toward a position where a vehicle arrives after a preset time so that the vehicle arrives at the position independently of a vehicle speed and which is feedback controlled so that an actual steering angle ratio or an actual wheel turning angle becomes the target steering angle ratio or the target wheel turning angle, the target steering angle ratio or the wheel turning angle is added and corrected depending on the steering angle speed of the steering wheel. Thus, the steering angle of steered wheel is automatically corrected corresponding to the steering angle speed given to the steering wheel by a driver, providing good maneuverability as a skilled person does without giving a great burden to the driver. |
