Abstract

In a method for selecting safety measures to be taken to increase the safety of occupants of a vehicle, which safety measures relate to a hazard due to environmental influences, a relevance of the hazard is inferred from received position data and warning message data, and at least one safety measure, which includes activation of an actuator in a vehicle, is selected and taken as a function of the relevance.

Claims

1. A method for selecting at least one safety measure to be taken to provide safety of occupants of a vehicle in response to a hazard due to environmental influences, comprising:

receiving position data of the vehicle;

receiving warning message data that identifies a position of the hazard due to environmental influences;

determining a type of the hazard based on classification data included in the warning message data, the classification data describing the type of the hazard according to one of a plurality of predefined hazard categories;

determining in the vehicle a relevance of the hazard to the vehicle based on a comparison between the position of the hazard and the received position data of the vehicle and further based on the received warning message data;

determining the relevance of the hazard based additionally on sensor data provided by at least one sensor unit among a plurality of sensor units in the vehicle that provide data relevant to different ones of the plurality of predefined hazard categories, the sensor data of the at least one sensor unit being relevant to the specific type of hazard described by the classification data; and

selecting and triggering at least one of multiple available safety measures as a function of the determined relevance of the hazard when the relevance, as determined based on both the comparison and the sensor data, indicates that there is a danger to the vehicle or a vehicle occupant, wherein the multiple available safety measures include at least one measure involving activation of an actuator in the vehicle;

wherein at least one of following is selected, as a function of the type of the hazard, as the at least one safety measure;

closing the vehicle'"'"'s windows;

positioning a rollover bar;

closing a vehicle roof; and

switching an air conditioning system or ventilation system to internal air circulation mode.

2. The method as recited in claim 1, wherein the selecting and triggering at least one safety feature includes determining as a function of the relevance of the hazard whether at least one safety measure involving activation of an actuator in the vehicle is selected.

3. The method as recited in claim 2, wherein the at least one safety measure is selected using selection data provided by a memory unit, wherein the selection data defines safety measures that vary depending on the type of hazard.

4. The method as recited in claim 2, wherein the at least one safety measure is selected using received measured data that is transmitted from a remote office and includes warning information for display to the driver.

5. The method as recited in claim 1, wherein the predefined hazard categories include strong moving air masses, fire hazards, shifting earth masses, water masses, snow masses and environmental disasters.

6. The method as recited in claim 1, wherein the at least one safety measure is selected to prevent gases from entering the vehicle.

7. The method as recited in claim 1, wherein the at least one safety measure is selected to keep a falling object away from a vehicle occupant.

8. The method as recited in claim 1, wherein the at least one safety measure is selected to protect a vehicle occupant from rocking motions caused by the hazard.

9. A control unit for selecting at least one safety measure to be taken to provide safety of occupants of a vehicle in response to a hazard due to environmental influences, comprising:

a first interface configured to receive warning message data that identifies a position of the hazard due to environmental influences;

a second interface configured to receive position data of the vehicle;

a third interface configured to interact with at least one actuator;

a fourth interface configured to interface with a plurality of sensor units of the vehicle, the sensor units providing data relevant to different ones of a plurality of predefined hazard categories; and

an arithmetic unit configured to;

determine a type of the hazard based on classification data included in the warning message data, the classification data describing the type of the hazard according to one of the predefined hazard categories;

determine a relevance of the hazard to the vehicle based on a comparison between the position of the hazard and the received position data of the vehicle and further based on the received warning message data;

determine the relevance of the hazard based additionally on sensor data provided by at least one sensor unit among the sensor units, the sensor data of the at least one sensor unit being relevant to the specific type of hazard described by the classification data; and

select and trigger at least one of multiple available safety measures as a function of the determined relevance of the hazard when the relevance, as determined based on both the comparison and the sensor data, indicates that there is a danger to the vehicle or a vehicle occupant, in such a way that an actuator is activated via the third interface;

wherein the arithmetic unit selects, as a function of the type of the hazard, at least one of following as the at least one safety measure;

closing the vehicle'"'"'s windows;

positioning a rollover bar;

closing a vehicle roof; and

switching an air conditioning system or ventilation system to internal air circulation mode.

10. The control unit as recited in claim 9, wherein the predefined hazard categories include strong moving air masses, fire hazards, shifting earth masses, water masses, snow masses and environmental disasters.

11. The control unit as recited in claim 9, wherein the arithmetic unit selects the at least one safety measure to prevent gases from entering the vehicle.

12. The control unit as recited in claim 9, wherein the arithmetic unit selects the at least one safety measure to keep a falling object away from a vehicle occupant.

13. The control unit as recited in claim 9, wherein the arithmetic unit selects the at least one safety measure to protect a vehicle occupant from rocking motions caused by the hazard.
