A stability control system 24 for an automotive vehicle as includes a plurality of sensors 28-37 sensing the dynamic conditions of the vehicle and a controller 26 that controls a distributed brake force to reduce a tire moment so the net moment of the vehicle is counter to the roll direction. The sensors include a speed sensor 30, a lateral acceleration sensor 32, a roll rate sensor 34, a yaw rate sensor 20 and a longitudinal acceleration sensor 36. The controller 26 is coupled to the speed sensor 30, the lateral acceleration sensor 32, the roll rate sensor 34, the yaw rate sensor 28 and a longitudinal acceleration sensor 36. The controller 26 determines a roll angle estimate in response to lateral acceleration, longitudinal acceleration, roll rate, vehicle speed, and yaw rate. The controller 26 changes a tire force vector using brake force distribution in response to the relative roll angle estimate.
