Abstract

A crash notification system (12) for an automotive vehicle (10) is used to communicate with a communication network (22) and ultimately to a response center (24). The system (12) within vehicle (10) includes an occupant sensor (30) that generates an occupant sensor status signal. A crash sensor (34) a vehicle identification number memory (48), or a vertical acceleration sensor (46) may also be used to provide information to the controller (14). The controller (14) generates a communication signal that corresponds to the occupant sensor status signal and the other information so that appropriate emergency personnel may be deployed.

6. A crash notification system as recited in claim 5 wherein said seat belt switch comprises a front seat belt switch generating a front seat belt status signal.

7. A crash notification system as recited in claim 5 wherein said seat belt switch comprises a rear seat belt switch generating a rear seat belt status signal.

8. A crash notification system as recited in claim 1 wherein said seat belt switch comprises a front seat belt switch generating a front seat belt status signal and a rear seat belt switch generating a rear seat belt status signal, said controller generating a communication signal corresponding to said occupant sensor status signal, said rear seat belt status signal, said front seat belt status signal and said crash status signal.

9. A crash notification system as recited in claim 1 further comprising a vertical acceleration sensor generating a vertical acceleration signal, wherein said controller generates said communication signal corresponding to said occupant sensor status signal, the vertical acceleration sensor and the angular direction of force.

10. A crash notification system as recited in claim 1 further comprising a vehicle identification number memory having a vehicle identification number stored therein, said communication signal corresponding to said occupant sensor status signal, said vehicle identification number and the angular direction of force.

11. A crash notification system for a vehicle, said system coupled to a communication network having a response center comprising:

an occupant sensor generating an occupant sensor status signal;

a vertical acceleration sensor generating a vertical acceleration signal; and

a controller coupled to the occupant sensor and the vertical acceleration sensor, said controller determining a horizontal orientation of the vehicle relative to a road, said controller generating a communication signal that is communicated to the response center through the communication network, said communication signal corresponding to said occupant sensor status signal and the horizontal orientation.

12. A crash notification system as recited in claim 11 further comprising a vehicle identification number memory having a vehicle identification number stored therein, said communication signal corresponding to said occupant sensor status signal, said vertical acceleration, said vehicle identification number and the angular direction of force.

13. A crash notification system as recited in claim 11 further comprising a crash sensor coupled to said controller, said crash sensor comprises a front crash sensor generating a front crash signal, a side crash sensor generating a side crash signal or both.

14. A crash notification system as recited in claim 11 wherein said occupant sensor comprises a front seat occupant sensor, a rear seat occupant sensor, or both.

15. A crash notification system as recited in claim 11 further comprising a seat belt switch generating a seat belt status signal, said controller generating a communication signal corresponding to said occupant sensor status signal, said horizontal orientation and said seat belt status signal.

16. A crash notification system as recited in claim 15 wherein said seat belt switch comprises a front seat belt switch generating a front seat belt status signal or a rear seat belt switch generating a rear seat belt status signal, or both.

17. A crash notification system as recited in claim 11 wherein said seat belt switch comprises a front seat belt switch generating a front seat belt status signal and a rear seat belt switch generating a rear seat belt status signal, said controller generating a communication signal corresponding to said occupant sensor status signal, said rear seat belt status signal, said front seat belt status signal and said horizontal orientation.

18. A crash notification system for a vehicle, said system coupled to a communication network having a response center comprising:

an occupant sensor generating an occupant sensor status signal;

a vehicle identification number memory having a vehicle identification number stored therein; and

a controller coupled to the occupant sensor and the vehicle identification number memory, said controller generating a communication signal that is communicated to the response center through the communication network, said communication signal corresponding to said occupant sensor status signal and the vehicle identification number.

19. A crash notification system as recited in claim 18 wherein the response center generates a decoded vehicle signal in response to the vehicle identification signal.

20. A crash notification system as recited in claim 18 further comprising a crash sensor coupled to said controller, said crash sensor comprises a front crash sensor generating a front crash signal, a side crash sensor generating a side crash signal or both.

21. A crash notification system as recited in claim 18 wherein said occupant sensor comprises a front seat occupant sensor, a rear seat occupant sensor, or both.

22. A crash notification system as recited in claim 18 further comprising a seat belt switch generating a seat belt status signal, said controller generating a communication signal corresponding to said occupant sensor status signal, said horizontal orientation and said seat belt status signal.

23. A crash notification system as recited in claim 22 wherein said seat belt switch comprises a front seat belt switch generating a front seat belt status signal or a rear seat belt switch generating a rear seat belt status signal, or both.
