Abstract
A stability control system (24) for an automotive vehicle as includes a plurality of sensors (28-39) sensing the dynamic conditions of the vehicle and a controller controls a steering force to reduce a tire moment so the net moment of the vehicle is counter to the roll direction. The sensors may 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 by changing the direction and/or force of the steering actuator in response to the relative roll angle estimate.
