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 pressure 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, and a yaw rate sensor 20. 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. The controller 26 determines a roll angle estimate in response to lateral acceleration, roll rate, vehicle speed, and yaw rate. The controller 26 may ultimately be used to determine a tire force vector such as brake pressure distribution or a steering angle change in response to the relative roll angle estimate.
