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) changes a tire force vector using brake pressure
distribution in response to the relative roll angle estimate.
