Steering handle position sensor checking apparatus

摘要

An apparatus for use with a vehicle dynamic characteristic control system employing a steering handle position sensor and a steering handle neutral position sensor to control the dynamic characteristics of an automotive vehicle. The steering handle position sensor is sensitive to steering handle position for producing a steering handle position signal indicative of a sensed steering handle position. The steering handle neutral position sensor is sensitive to steering handle position for producing a steering handle neutral position signal having a first level when the sensed steering handle position is in a predetermined neutral range and a second level when the sensed steering handle position is out of the predetermined neutral range. A first signal is produced when the steering handle position signal indicates the sensed steering handle position being out of a predetermined range including the neutral range. A second signal is produced when the steering wheel neutral position signal is at the first level. A failure signal is produced to indicate that the steering handle position sensor is subject to failure in the presence of both of the first and second signals.
