Abstract
A vehicle steering apparatus is configured to apply, to a steered wheel of a vehicle, a driving force for canceling a toe change amount caused by a road irregularity. The vehicle steering apparatus includes a road reaction force detector configured to detect a road reaction force received by a tire of the steered wheel, a toe adjustment actuator coupled to the steered wheel, and a controller configured to control a driving force of the toe adjustment actuator. The controller includes a toe change amount setter configured to set the toe change amount based on the road reaction force detected by the road reaction force detector, an operation amount calculator configured to calculate an actuator operation amount for canceling the toe change amount set by the toe change amount setter, and a driver configured to drive the toe adjustment actuator by the actuator operation amount calculated by the operation amount calculator.
