Abstract
A brake valve control method to control the operation of the brake valves is provided in which an error check can be made with one arithmetic logic unit. Signals from a wheel speed sensor are processed to compute the respective wheel speed, and signals from the wheel speed sensor are counted for a prescribed period to derive an approximate wheel speed. If the difference between the wheel speed and the approximate wheel speed is less than or equal to a threshold value, then processing to control the valves is continued; if the difference is greater than a threshold value, then processing to control the valves is suspended.
