A stability control system of a vehicle utilizing an electronic control unit that minimizes rollback of a vehicle as a result of wheel slip immediately following a hill start assist operation. The electronic braking control module controls actuation and de-actuation of vehicle brakes on an inclined surface. Immediately following a hill start assist operation on the inclined surface after each wheel brake is de-actuated for allowing forward movement of the vehicle up the hill, a split-mu road surface condition is detected in response to sensing wheel slip for each of the wheels. The electronic control unit determines a respective undriven, or non-dominant driven, wheel having the highest coefficient of friction among the undriven, or less dominant driven wheels, as determined by the wheel speeds. The electronic braking control module actuates the vehicle brake of the undriven, or less dominant, driven wheels having the highest coefficient of friction relative to a tire/road surface interface for reducing rollback of the vehicle. The braking of the undriven, or less dominant, driven wheel is in addition to any standard stability control braking that may already be occurring.
