Abstract
A rear wheel steering angle control apparatus is provided with a rear wheel steering angle determining unit and a rear wheel steering mechanism so as to determine a steering angle ratio based upon vehicle speed and perform a rear wheel steering angle control. An alerting unit alerts that the output of the rear wheel steering mechanism is beyond a predetermined allowable range when an observing unit detects a control condition being abnormal and releases the alert when the output of the rear wheel steering mechanism is within the predetermined allowable range.
