How can an airbag know when it should go up or not?
In: Technology
There are sensors positioned at multiple points in the car. These are connected to a computer which determines which airbags to deploy. What determines if they deploy at all is dependent on the energy of the collision. Low speed collisions under 15mph will probably not trigger the airbags. Side collisions will trigger the side curtain airbags (Some cars may deploy them in front collisions too). Rear end collisions will usually not deploy airbags. There’s also seat sensors, if there’s not a significant amount of weight on the seat, that sides airbags will not deploy. This is to help prevent injuries to children sitting in those seats. It can also save repair costs if you’re in an accident that is not severe enough to total the car; As airbag replacements are expensive.
