Abstract
A misalignment detection system ( ) for steering systems of an automotive vehicle ( ) includes a logic device ( ) coupled to a vehicle speed sensor ( ) and a steering wheel angle sensor ( ). The logic device is also coupled to a memory ( ) that is used to store a steering wheel ratio map and a historic steering wheel angle or a wheel angle value derived from an automobile manufacturer's wheel alignment specification. The logic device ( ) compares the signal from the steering wheel angle sensor ( ) with the stored value of either the historic steering wheel angle or the value derived from the manufacturer's alignment specifications at a given vehicle speed to determine error. An indicator ( ) may provide an indication to the vehicle operator to signal the presence of the misalignment condition of the steering system.
