Patent ID: 7222007

Claim:
A system for controlling a safety system of an automotive vehicle comprising: a longitudinal acceleration sensor generating a longitudinal acceleration signal; a vehicle speed sensor generating a vehicle speed signal; a lateral acceleration sensor generating a lateral acceleration signal; a yaw rate signal generating a yaw rate signal; and a controller coupled to the longitudinal acceleration sensor, the vehicle speed sensor, the lateral acceleration sensor and the yaw rate sensor, said controller determining a reference pitch in response to the longitudinal acceleration signal and the vehicle speed signal and a reference roll angle in response to said yaw rate signal, the wheel speed signal and said lateral acceleration signal, said controller determining a roll stability index and a pitch stability index, said controller determining an adjusted pitch angle in response to the reference pitch angle and the pitch stability index and an adjusted roll angle in response to the reference roll angle and the roll stability index, said controller controlling the safety system in response to the adjusted roll angle and the adjusted pitch angle.
