Abstract

A method for controlling triggering of at least one passenger protection device for a vehicle. The method includes a step of determining whether a signal level of at least one read-in impact signal, which represents a change in a vehicle condition indicating a potential collision of the vehicle with a potential accident object, exceeds an evaluation limiting value. The method also includes a step of using a high triggering threshold value for triggering of the at least one passenger protection device when the signal level of the at least one read-in impact signal exceeds the evaluation limiting value.

First claim

What is claimed is:

1 . A method for controlling a triggering of at least one passenger protection device for a vehicle, the method comprising:
determining whether a signal level of at least one read-in impact signal, which represents a change in a vehicle condition indicating a potential collision of the vehicle with a potential accident object, exceeds an evaluation limiting value; and using a high triggering threshold value for triggering of the at least one passenger protection device when the signal level of the at least one read-in impact signal exceeds the evaluation limiting value.

2 . The method as recited in claim 1 , wherein in the determining step, determining whether the signal level of the at least one read-in impact signal exceeds the evaluation limiting value at least one of: i) before a minimum period prior to the potential collision has been reached, and ii) when the potential accident object is detected a maximum distance away from the vehicle.

3 . The method as recited in claim 1 , wherein in the using step, a low triggering threshold value is used for triggering of the at least one passenger protection device when the signal level of the at least one read-in impact signal falls below the evaluation limiting value.

4 . The method as recited in claim 3 , wherein in the using step, the low triggering threshold value is used within a time window, which includes an ascertained point in time of the potential collision of the vehicle with an accident object.

5 . The method as recited in claim 3 , wherein in using step, the high triggering threshold value is used when the signal level of the at least one read-in impact signal at least one of: i) exceeds the evaluation limiting value for a minimum period, and ii) exceeds the evaluation limiting value repeatedly within a minimum period.

6 . The method as recited in claim 3 , further comprising:
reading in surroundings data with regard to surroundings of the vehicle, wherein, in the using step, either the high triggering threshold value or a triggering threshold value different from the high triggering threshold value is used, depending on the read-in surroundings data.

7 . The method as recited in claim 6 , wherein in the reading in step, the surroundings data are read in by an interface to a device for providing map-based surroundings data, which represent a triggering threshold value recommended for at least one of: i) the surroundings of the vehicle, ii) a road condition characteristic of the surroundings of the vehicle, iii) a road surface characteristic of the surroundings of the vehicle, and iv) at least one additional road characteristic in the surroundings of the vehicle.

8 . The method as recited in claim 6 , wherein in the reading in step, the surroundings data are read in from an interface to at least one detection device for providing sensor-based surroundings data representing at least one of: i) a road condition, ii) a road surface, and iii) at least one additional road characteristic in the surroundings of the vehicle.

9 . The method as recited in claim 6 , wherein in the reading in step, the surroundings data are read in from an interface to at least one detection device for providing sensor-based surroundings data representing a potential accident object to ascertain the potential collision.

10 . A device configured to carry out or activate a method for controlling a triggering of at least one passenger protection device for a vehicle, the method comprising:
determining whether a signal level of at least one read-in impact signal, which represents a change in a vehicle condition indicating a potential collision of the vehicle with a potential accident object, exceeds an evaluation limiting value; and using a high triggering threshold value for triggering of the at least one passenger protection device when the signal level of the at least one read-in impact signal exceeds the evaluation limiting value.

11 . A safety system for a vehicle, comprising:
at least one passenger protection device; and a device designed to determine whether a signal level of at least one read-in impact signal, which represents a change in a vehicle condition indicating a potential collision of the vehicle with a potential accident object, exceeds an evaluation limiting value, and use a high triggering threshold value for triggering of the at least one passenger protection device when the signal level of the at least one read-in impact signal exceeds the evaluation limiting value,

12 . A non-transitory, machine-readable memory medium storing a computer program for controlling a triggering of at least one passenger protection device for a vehicle, the computer program, when executed by a processor, causing the processor to perform:
determining whether a signal level of at least one read-in impact signal, which represents a change in a vehicle condition indicating a potential collision of the vehicle with a potential accident object, exceeds an evaluation limiting value; and using a high triggering threshold value for triggering of the at least one passenger protection device when the signal level of the at least one read-in impact signal exceeds the evaluation limiting value.
