METHOD AND CONTROL UNIT FOR CONTROLLING AT LEAST ONE ASSISTANCE FUNCTION IN THE EVENT OF A ROLLOVER OF A VEHICLE, AND ASSISTANCE SYSTEM
First Claim
1. A method for controlling at least one assistance function in the event of a rollover of a vehicle, the vehicle including at least one acceleration sensor with zero point feedback, the method comprising:
- one of;
(i) reading in a sensor signal and a feedback signal, or (ii) reading in the sensor signal and ascertaining the feedback signal using the sensor signal, the sensor signal representing acceleration values detected by the at least one acceleration sensor, and the feedback signal representing control values for the zero point feedback of the at least one acceleration sensor;
carrying out a first comparison of the sensor signal to a first threshold value and to a second threshold value, and carrying out a second comparison of the feedback signal to a third threshold value, the first threshold value and the second threshold value representing acceleration values, the first threshold value being associated with a static tilt angle of the vehicle and representing a higher acceleration value than the second threshold value, and the third threshold value representing a control value that is associated with a difference between the first threshold value and the second threshold value;
determining an occurrence of a rollover as a function of a result of the first comparison and of a result of the second comparison; and
providing a rollover signal for output to the at least one assistance function when the occurrence of a rollover has been determined in the determining step.

Abstract
A method for controlling at least one assistance function in the event of a rollover of a vehicle. The vehicle includes at least one acceleration sensor with zero point feedback. The method includes reading in a sensor signal and ascertain or reading a feedback signal. The sensor signal represents acceleration values detected by the at least one acceleration sensor. The feedback signal represents control values for the zero point feedback of the at least one acceleration sensor. The method also includes determining an occurrence of a rollover as a function of a result of comparisons. Furthermore, the method includes providing a rollover signal for output to the at least one assistance function. The rollover signal represents a recognized rollover of the vehicle.
