ABSTRACT:
A method and apparatus for determining the stability of an automotive vehicle includes a steering wheel sensor generating a steering wheel signal, a yaw rate sensor generating a yaw rate signal and a lateral acceleration sensor for generating a lateral acceleration signal. A controller is coupled to the steering wheel sensor, the yaw rate sensor, and the accelerometer. The controller determines a first steering wheel angle from the yaw rate signal, a second steering wheel angle from the lateral acceleration signal, and a third steering angle from a steering wheel signal. The controller generates a vehicle stability indicator in response to the first steering wheel angle, the second steering wheel angle and the third steering wheel angle.
