Abstract:
1. A device for determining a tendency to tilt about a longitudinal axis and a tendency to turn about a vertical axis of a vehicle, using a detection system comprising: a lateral acceleration sensor producing a lateral acceleration signal; a yaw rate sensor producing a yaw rate signal; a steering angle sensor producing a steering angle signal; wheel speed sensors producing rotation signals of respective wheels; and a controller which, in response to a steering angle, a steering velocity and a vehicle speed, determines a tendency to tilt about a longitudinal axis of the vehicle and in response to the lateral acceleration sensor, the yaw rate sensor, the steering angle sensor and the wheel speed sensors determines a tendency to turn about a vertical axis of a vehicle, and the controller generates a triggering signal for at least one passenger protection device depending on the extent of these tendencies.
