Method and device for activating additional functions in response to a rollover procedure of a motor vehicle
First Claim
1. A method for activating additional functions in response to a rollover procedure of a vehicle, using at least one sensor and one control unit, the sensor supplying at least one unidirectional acceleration signal, the method comprising:
- (S1) analyzing at least one acceleration signal in its characteristics as a function of time, so as to provide analyzed values;
(S2) processing the analyzed values of the at least one acceleration signal;
(S3) establishing the plausibility of the processed values using a second signal value; and
(S4) activating at least one additional non-safety-critical function in response to a rollover procedure of the vehicle in the light of the values whose plausibility has been established.

Abstract
A method for activating additional functions in response to a rollover procedure of a vehicle, using at least one sensor and one control unit, the sensor supplying at least one unidirectional acceleration signal, having the following method steps: analyzing at least one acceleration signal in its characteristics as a function of time; processing analyzed values of the at least one acceleration signal; establishing the plausibility of the processed values using a second signal value; and activating at least one additional function in response to a rollover procedure of the vehicle in the light of the values whose plausibility has been established; as well as a control device using this method.
