Abstract
A method of controlling the deceleration of a vehicle to account for an increase in friction in the vehicle brake system as the vehicle decelerates. The method comprises receiving a signal indicative of a value of the speed of the vehicle and a signal indicative of a value of a brake pressure in the vehicle brake system. The method further comprises comparing the vehicle speed value and the brake pressure value to respective thresholds. The method still further comprises increasing the drive torque applied to one or more wheels of the vehicle when the vehicle speed value falls below the threshold to which it was compared and the brake pressure value exceeds the threshold to which it was compared, such that the increased drive torque acts against the braking of the vehicle as the vehicle is decelerated to a stop.
