Abstract
A vehicle dynamic characteristic control apparatus for use with a motor vehicle having controllable dynamic characteristics. The apparatus comprises a first sensor sensitive to steering handle position for producing an electric signal indicative of a sensed steering handle position, and a second sensor 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 range and a second level when the sensed steering handle position is out of the predetermined range. A control unit is coupled to the first and second sensors. The control unit checks the steering handle neutral position signal. An estimation start command signal is produced when the steering handle neutral position signal is normal. The control unit estimates a steering handle neutral position in response to the estimation start command and controls the dynamic characteristics of the automotive vehicle based on the estimated steering handle neutral position.
