Method and system to control airbag deployment for a pregnant occupant
A method and system for controlling airbag deployment in a vehicle. The method may include the steps of receiving an input that a driver of the vehicle is pregnant, and changing an airbag deployment setting to account for a space reduction between the driver and an interior panel portion of the vehicle. In one implementation, the interior panel portion of the vehicle is a steering wheel.
1. A method of controlling airbag deployment in a vehicle, comprising:
receiving an input that a driver of the vehicle is pregnant; and
changing an airbag deployment setting to account for a space reduction between the driver and an interior panel portion of the vehicle, wherein the airbag deployment setting is a deployment delay factor.
2. The method of claim 1 , wherein the deployment delay factor is about 20-100 msec, inclusive, from a crash signal.
3. The method of claim 1 , wherein the airbag deployment setting is an inflation adjustment parameter to adjust an inflator of the airbag.
4. The method of claim 3 , wherein the inflation adjustment parameter is a gas flow rate.
5. The method of claim 4 , wherein the gas flow rate is reduced after receiving the input that the driver of the vehicle is pregnant.
6. The method of claim 3 , wherein the inflation adjustment parameter is a deployment volume reduction.
7. The method of claim 3 , wherein the inflation adjustment parameter is an airbag intensity factor.
8. The method of claim 1 , wherein the airbag deployment setting is a tilt angle of deployment.
9. The method of claim 8 , wherein the interior panel portion is a steering wheel and the tilt angle of deployment is a steering wheel angle.
10. The method of claim 9 , wherein the steering wheel angle changes a face of the steering wheel to an angle between 20-80°, inclusive.
11. The method of claim 9 , wherein the steering wheel angle at least partially orients a face of the steering wheel away from a midsection of the driver.
12. The method of claim 1 , wherein the interior panel portion of the vehicle is a steering wheel and the airbag deployment setting is a linear position adjustment to the steering wheel.
13. The method of claim 1 , wherein the airbag deployment setting is a change in a vertical height of a front surface of the airbag that is configured to contact a midsection of the driver.
14. The method of claim 1 , wherein the input is received via an infotainment cluster.
15. The method of claim 14 , further comprising the step of sending a signal from an infotainment module to an airbag control module.
16. The method of claim 15 , wherein the signal is transmitted between the infotainment module and the airbag control module via a body control module.
17. A method of controlling airbag deployment in a vehicle, comprising:
receiving an input that a driver of the vehicle is pregnant; and
changing an airbag deployment setting to account for a space reduction between the driver and an interior panel portion of the vehicle, wherein the airbag deployment setting is an inflation adjustment parameter to adjust an inflator of the airbag, the inflation adjustment parameter is an airbag intensity factor, and wherein the airbag intensity factor is a deployment time difference between the inflator and a second inflator.
18. A system for controlling airbag deployment in a vehicle, comprising:
an infotainment cluster configured to receive an input that a driver of the vehicle is pregnant;
an airbag control module having a controller configured to receive the input that the driver of the vehicle is pregnant from the infotainment cluster and change an airbag deployment setting for an airbag to account for a space reduction between the driver and an interior panel portion of the vehicle wherein the airbag deployment setting is a deployment delay factor.
19. The system of claim 18 , wherein the interior panel portion is a steering wheel and the airbag is a steering wheel airbag.
