In collision,the sensor delivers the collision signal to airbag controller,and the controller,according to the collision degree,judges whether it reaches the minimum requirement of airbag detonation and then sends the ignition order to denote the airbag,which will form a soft bag full of gas between the passengers and structural parts(such as steering wheel,instrument panel)and the damp effect of releasing air from airbag will mitigate and absorb the collision power so as to reduce the damage to the passengers.
