Abstract
A brake control system for controlling an amount of braking force applied to a wheel of a vehicle running on a surface, comprising a sensor for measuring a speed of the wheel and for providing an output signal indicative of the speed; and a controller, operatively coupled to the sensor, which implements a Kalman filter to estimate an amplitude and location of a peak in a mu-slip curve representative of a coefficient of friction between the wheel and the surface based on the output signal of the sensor, and which controls the amount of braking force applied to the wheel based on the amplitude and location of the peak.
