Airbag computers already log the acceleromter/brake pedal data they used to make the decision to fire.
This was introduced to protect the makers - there were lots of fears/claims that airbags had gone off and caused crashes. The car makers wanted to prove that you were braking hard or had hit some thing when they fired.
I suspect 'a reasonable time' means that the system needs an internal battery/static memory so that the data is available later after the engine is turned off or if the car battery is disconnected in the accident.
- grecy 15y agoMy understanding is that airbags are triggered when a threshold of very sudden deceleration is crossed and has nothing to do with the brake pedal.
- excuse-me 15y agoMine at least is linked into the rest of the car - it sense weight on the seat and I think it's only active when the key is in. Obviously it wouldn't be coded fire only if you were braking ! But it might be at least logging all the data that is used for the seat belt pre-tensioning, ABS, stability control, traction control and all the other safety systems.
