If a collision should occur, intelligent sensors trigger off the occupant restraint systems at the correct moment. The crash sensors must be able to detect a collision and convert it into corresponding signals within a matter of milliseconds. The nerve centre of this system is the airbag control unit, which decides whether to activate it and, depen [..]

The crash sensors must be able to detect a collision and convert it into corresponding signals within a matter of milliseconds. The accelerating forces acting on the sensors immediately after a collision can be as high as 100 g (100 times the earth’s gravitational force). The measurement principle employed by the crash sensors is usually based on t [..]
