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.
Claims7
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.
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.
