Abstract
Apparatus and associated methods relate to controlling a brake mechanism during braking operation to provide near-maximal braking power. Maximal braking power occurs at when the wheel slip has a target value. Wheel slip can be monitored during braking operation so as to be used in control the brake mechanism to operate at the maximal braking power. The braking power is modulated so as to dither the braking power about a nominal braking power. The monitored wheel slip will have a dither component in response to the dithering of the braking power. A volatility of the dither component of the monitored wheel slip can be indicative of nominal braking power proximity to the maximal braking power. A nominal brake signal can be generated so as to change the nominal braking power in the direction of the maximal braking power based on the volatility of the dither component of the monitored wheel slip.
