Abstract:
A stability control system for an automotive vehicle comprising:a speed sensor generating a first signal corresponding to wheel speed of the vehicle; a lateral acceleration sensor generating a second signal corresponding to lateral acceleration of the vehicle; a roll rate sensor generating a third signal corresponding to a roll rate of the vehicle; a yaw rate sensor generating a fourth corresponding to a yaw rate of the vehicle; a longitudinal acceleration sensor generating a fifth signal corresponding to longitudinal acceleration of the vehicle; and a controller coupled to said speed sensor, said lateral acceleration sensor, said roll rate sensor, said yaw rate sensor and said longitudinal acceleration sensor, said controller determining a roll angle estimate as a function of lateral acceleration, roll rate, vehicle speed, and yaw rate and longitudinal acceleration, and changing a tire force vector in response to the relative roll angle estimate.
