Abstract

A method of deploying a side impact airbag is provided. The method includes selectively determining a delay time based on an impact type, where the delay time associated with an impact on a first side is different than the delay time associated with an impact on a second side; and selectively generating a control signal to at least one of deploy and not deploy the side impact airbag based on the delay time.

Claims (32)

1. A method of deploying a side impact airbag of a vehicle, comprising:

at least one airbag that is disposed between a first occupant seating position of a first side of the vehicle and a second occupant seating position of a second side of the vehicle; and

selectively determining a delay time based on an impact type, a suppression determination, and a determination of occupied seats in a vehicle, where the delay time associated with an impact on a first side of the vehicle is different than the delay time associated with an impact on a second side of the vehicle; and

selectively generating a control signal via a control module having a processor to at least one of deploy and not deploy the side impact airbag based on the delay time and said deployment of said airbag is responsive to said delay time for each side of the vehicle so that deployment time of said airbag on the first side of the vehicle is different than deployment time of said airbag on the second side of the vehicle.

2. The method of claim 1 wherein at least one of the selectively determining the delay time and the selectively generating the control signal is further based on at least one of a suppression state for rendering the suppression determination, and a seatbelt state.

3. The method of claim 2 wherein the suppression state indicates whether an occupant is seated in a seat on the second side.

4. The method of claim 2 wherein the seatbelt state indicates whether an occupant is belted into a seat on the first side of the vehicle.

5. The method of claim 2 wherein the first side of the vehicle is a driver side and the second side of the vehicle is a passenger side.

6. The method of claim 5 wherein at least one of the selectively determining the delay time and the selectively generating the control signal occurs when at least one of:

an impact is on the driver side;

the impact is on the driver side and the suppression state indicates the occupant is seated on the passenger side;

the impact is on the driver side and the seatbelt state indicates the occupant is belted and the suppression state indicates the occupant is not seated on the passenger side; and

the seatbelt state indicates that an occupant is not belted and the suppression state indicates that an occupant is not seated on the passenger side.

7. The method of claim 1 wherein the first side of the vehicle is a first passenger side and the second side of the vehicle is a second passenger side that is opposite of the first passenger side.

8. The method of claim 1 wherein a delay time associated with an impact on a third side of the vehicle is different than at least one of the delay time associated with the impact on the first side of the vehicle and the delay time associated with the impact on the second side of the vehicle.

9. The system of claim 8 wherein the third side of the vehicle is at least one of a front side a rear side, and a top side.

10. An airbag deployment system, comprising:

at least one airbag that is disposed between a first occupant seating position of a first side of a vehicle and a second occupant seating position of a second side of the vehicle; and

an actuation unit responsive to the control module such that the actuation unit deploys the at least one airbag after a delay time occurs, wherein at least one of the delay time and the deployment is selectively determined based on an impact type a suppression determination, and a determination of occupied seats in the vehicle, where the delay time associated with deployment on the first side of the vehicle is different than the delay time associated with deployment on the second side of the vehicle.

11. The system of claim 10 further comprising a delay determination module that selectively determines the delay time based on the impact type.

12. The system of claim 11 wherein the delay determination module further determines the delay time based on at least one of a suppression state, and a seatbelt state.

13. The system of claim 11 further comprising a deployment module that selectively generates a deployment signal based on the delay time, and wherein the actuation unit deploys the airbag based on the deployment signal.

14. The system of claim 10 wherein the first occupant seating position is a passenger seating position.

15. The system of claim 14 wherein the second occupant seating position is a driver seating position.

16. The system of claim 14 wherein the second occupant seating position is a passenger seating position.

17. The system of claim 10 wherein an impact on a third side of the vehicle not associated with the first occupant seating position and the second occupant seating position is different than at least one of the delay time associated with the impact on the first side of the vehicle and the delay time associated with the impact on the second side of the vehicle.

18. The system of claim 17 wherein the third side of the vehicle is at least one of a front side, a rear side, and a top side.

19. A vehicle, comprising:

a plurality of airbags wherein at least one airbag is disposed between a first occupant seating position of a first side of the vehicle and a second occupant seating position of a second side of the vehicle;

a control module that selectively determines at least one of a decision to deploy and a delay time based on an impact type, where the delay time associated with an impact on the first side is different than the delay time associated with an impact on the second side and deployment of the airbag on a first side of the vehicle is different than deployment time of the airbag on a second side of the vehicle

an actuation unit that deploys the at least one airbag after the delay time occurs.

20. The vehicle of claim 19 wherein the control module further determines the at least one of decision to deploy and delay time based on at least one of a suppression state, and a seatbelt state.
