  • Method and apparatus for measuring the wheel speed
    Patent number: 6166534
    Abstract: A method and device for calculating vehicle wheel speed which counts either one of the rise or the fall of each one of the pulse signals of the wheel sensor when the wheel speed is higher than a certain amount and counts both the rise and the fall of the pulse signals when the wheel speed is lower than the certain amount. This invention reduces the calculation time for the vehicle wheel speed.
