Vehicle wheel rotation detecting system and method

In a vehicle wheel rotation detecting system, a signal input portion (10a) of an ECU accurately detects a vehicle wheel speed and a rotating direction of the vehicle wheel speed of the respective wheels (12, 14, 16, 18). On the basis of the detected results, the respective computers are operated to perform ABS control, TC control and VSC control. When a computing result of the vehicle wheel speed is equal to or greater than a predetermined value, a change in the rotating direction is inhibited. This may prevent an error in the result of detection of the wheel rotating direction owing to an external magnetic filed and the like so as to further optimize the vehicle state control.
