Abstract

A safety apparatus for a motor vehicle, comprising: a plurality of occupant protection devices and sensors associated with them; a processing device that checks whether the occupant protection devices and/or associated sensors are in operation and/or properly functional, and ascertains status information therefrom; and an output device that, in consideration of all the status information, communicates the operating status possessed by each individual occupant protection device and/or sensor. Also described is a method for communicating the status of a safety apparatus of a motor vehicle.

Claims

1-13. -13. (canceled)

14. A safety apparatus for a motor vehicle, comprising:

a plurality of occupant protection elements;

a plurality of sensors associated with the plurality of occupant protection elements;

a processing device that checks whether at least one of the occupant protection elements and the associated sensors are at least one of in operation and properly functional, the processing device ascertaining status information from at least one of the occupant protection elements and the associated sensors; and

an output device that, in consideration of the status information, communicates an operating status possessed by at least one of each individual occupant protection element and each sensor.

15. The apparatus as defined in claim 14, further comprising:

at least one further sensor that senses a seating position of at least one occupant, wherein;

the processing device takes a sensed signal from the at least one further sensor into account in ascertaining the status information.

16. The apparatus as defined in claim 14, wherein:

the processing device includes a calculation device that, from the status information, calculates an individual occupant safety level for at least one of a driver and a passenger and outputs the individual occupant safety level via the output device.

17. The apparatus as defined in claim 14, wherein:

the output device includes at least one of;

at least one of a driver display, a separate passenger display, and a central display having separate indicators for driver and passenger for optical communications,

a windshield protection device for optical communications,

a voice output device for acoustic communications,

a warning tone device for acoustic communications, and

at least one of an electrically displaceable seat and a reversible belt tensioner for haptic communications.

18. The apparatus as defined in claim 14, further comprising:

a central data transmission device to which the processing device is connected and that makes further current vehicle data available to the processing device for inclusion.

19. The apparatus as defined in claim 18, wherein:

the current vehicle data is coupled via the central data transmission device into at least one of a filtering device and an extraction device of the processing device, and

the current vehicle data encompass data from at least one of an ABS system and an ESP system.

20. The apparatus as defined in claim 14, further comprising at least one of:

a monitoring device for monitoring at least one of a driver airbag and a passenger airbag;

a pre-crash sensor device; and

an emergency seat displacement device.

21. The apparatus as defined in claim 20, wherein:

the processing device includes at least one of a filtering device and an extraction device,

the at least one of the filtering device and the extraction device filters a signal of the monitoring devices and is connected to a GPS device that supplies vehicle position data for inclusion.

22. The apparatus as defined in claim 18, wherein the processing device includes an output for outputting data to the central data transmission device.

23. The apparatus as defined in claim 14, wherein the processing device includes a storage device for providing a nonvolatile storage of at least one of processed data and status information.

27. The apparatus as recited in claim 14, wherein the at least one occupant includes at least one of a driver and a passenger.

28. The apparatus as recited in claim 18, wherein the central data transmission device includes a CAN bus.

24. A method for communicating a status of a safety apparatus of a motor vehicle, comprising:

checking whether at least one of a plurality of occupant protection elements and an associated plurality of sensors are at least one of in operation and properly functional;

ascertaining status information from the at least one of the plurality of occupant protection elements and the associated plurality of sensors; and

outputting, in consideration of the status information, an operating status possessed by at least one of each individual occupant protection element and each sensor.

25. The method as defined in claim 24, further comprising:

evaluating the status information in the processing device; and

ascertaining in and communicating to at least one occupant from the processing device an occupant safety level at least one of before driving and while driving.

26. The method as defined in claim 24, wherein for each individual occupant, an occupant protection level specified for him is ascertained and outputted.
