Method for classifying a rollover event of a vehicle
First Claim
1. A method of classifying a rollover event of a vehicle, the method comprising:
- using restraint devices as a function of a rollover event;
classifying the rollover event as a function of a rotational angle and a rotation rate of the vehicle; and
transmitting an emergency call as a function of the classification.

Abstract
A method for classifying a rollover event of a vehicle is used to classify a rollover event on the basis of a rotational angle and a rotation rate of the vehicle and to transmit an emergency call as a function of the classification. The rollover event itself is recognized on the basis of a momentum or energy criterion. The rotation rate is summed to determine the rotational angle, the summed rotation rate as well as the rotation rate being compared to classification boundaries as a pair of values in order to perform a classification. The emergency call is made only if the restraint devices have been deployed.

5. A device comprising:
-
means for recognizing a rollover event of a vehicle;
a rotation-rate sensor;
a transmitter; and
a processor coupled to the rotation-rate sensor, the processor classifying the rollover event as a function of a rotation rate and a rotational angle of the vehicle, the processor being adapted to be connected (a) to the transmitter to transmit an emergency call as a function of the classification of the rollover event and (b) to restraint devices of the vehicle. - View Dependent Claims (6, 7)
