Abstract: An apparatus for use with a vehicle dynamic characteristic control system employing a vehicle speed sensor, a steering handle position sensor and a steering handle neutral position sensor to control the dynamic characteristics of an automotive vehicle. The vehicle speed sensor is sensitive to vehicle speed for producing a vehicle speed signal indicative of a sensed vehicle speed. 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 steering handle neutral position is estimated based upon the steering handle position signal and the steering handle neutral position signal. A steering angle, which corresponds to an absolute value of a difference of the sensed steering handle position from the estimated steering handle neutral position, is calculated. A failure signal is produced to indicate that at least one of the steering handle position sensor and the steering handle neutral position sensor is subject to failure when the calculated steering angle is equal to or greater than a predetermined value and when the vehicle speed is held above a predetermined value normal for vehicle running in an urban area for a predetermined interval of about 60 seconds.

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.

Abstract: Under an automatic turning control, a steering controller defines a value of steering angle set according to a target turning angle of the automatic turning control, as a value of steering angle at which a reaction force is equal to 0. Thereby, the steering controller controls a steering reaction force on the basis of a difference between an actual steering angle and the value of steering angle at which the reaction force is equal to 0.

Abstract: A vehicle steering controller produces a steering system friction value and a tire lateral force value. A steering reactive force having a magnitude based on the tire lateral force value and the steering system friction value is generated for application to a steering wheel of the vehicle. By reflecting both the tire lateral force and the steering system friction in the steering reactive force, a good steering sensation can be realized in a steer-by-wire system.
