Abstract: The present invention is a brake control system for preventing the skidding of a wheel on a surface. The phase relationship between the brake pressure applied to the brakes and the torque created from the braking applied is determined. This relationship allows the present brake control system to maintain the wheels from skidding on a surface by maintaining a positive slope of such brake pressure and torque phase relationship. A second embodiment provides a backup system wherein the percentage of slip is determined and compared to an input percentage slip. The second embodiment system overrides the torque command system when the torque command system fails.
