How does a car detect it is in a collision to activate the airbags?
In: Other
There are accelerometer sensors in the frame/body of the vehicle. These accelerometers triggers the airbags when they detect an acceleration due to impact that is above a certain threshold.
Older cars used pressure pads behind the bumpers. Newer cars use g-force sensor chips mounted in the cab to detect force, angle, and extreme changes in speed and direction.
