Abstract
A vehicular steering apparatus according to the invention includes a steering angle correction mechanism, a steering power assist mechanism, and a controller. The steering angle correction mechanism works to provide a correction steering angle to a steerable road wheel of a vehicle. The steering power assist mechanism is configured to provide the steerable road wheel of the vehicle with a base assist power and a correction assist power in a first operation mode and the base assist power and a limited correction assist power in a second operation mode. The controller works to control the steering angle correction mechanism to provide the correction steering angle to the steerable road wheel. The controller also works to control the steering power assist mechanism to operate in the first operation mode if the absolute value of the correction steering angle is greater than a predetermined value and in the second operation mode otherwise.
