VEHICLE STEERING CONTROL APPARATUS

摘要

A vehicle steering control apparatus in a vehicle, which is provided with: a tire steer angle varying apparatus which is configured to change a tire steer angle independently of steering wheel operation; and a tire steer angle equivalent value detecting device which is configured to detect a tire steer angle equivalent value corresponding to the tire steer angle, is provided with: a learning device which is configured to learn a steering wheel angle neutral point; an abnormality determining device which is configured to determine whether or not the tire steer angle equivalent value detecting device is in an abnormal state; a disregarding device which is configured to disregard the learned steering wheel angle neutral point if it is determined that the tire steer angle equivalent value detecting device is in the abnormal state; a controlling device which is configured to control the tire steer angle varying apparatus such that the tire steer angle is returned to a tire steer angle neutral point if it is determined that the tire steer angle equivalent value detecting device is in the abnormal state; and an initializing device which is configured to initialize the tire steer angle equivalent value detecting device after the tire steer angle is returned to the tire steer angle neutral point, wherein the leaning device restarts the learning of the steering wheel angle after the tire steer angle equivalent value detecting device is initialized.
