Abstract
PURPOSE:To precisely detect the fail of a handle neutral position sensor within a minimum time by detecting the fail by the presence of handle neutral position detection signal during the vehicle running of a fail judging distance corresponding to the vehicle speed. CONSTITUTION:At the time of vehicle running, a dynamic characteristic control means (c) inputs handle steering angle signal from a sensor (a) and handle neutral position signal from a sensor (b) and controls the vehicle dynamic characteristic most properly. During this vehicle running, when the handle neutral position is not detected by the sensor (b) during the running of a fail judging distance set by a setting means (e), this is detected as a sensor fail by a handle neutral position sensor fail detecting means (f). In this case, the fail judging distance setting means (e) sets the fail judging distance shorter as the vehicle speed from a vehicle speed detecting means (d) is higher. Hence, the fail of the handle neutral position sensor can be precisely detected within a minimum time.
