Up-Front Sensors

Up-Front Sensors





Not all federal states require car occupants to wear seat belts, so adequate provision must be made to ensure that the airbag can reliably restrain the occupant in the event of a crash.
The up-front sensors in the vicinity of the front left and right engine bearers detect deformation in the crumple zone and thus register energy absorption. The up front sensors are acceleration sensors that measure longitudinal acceleration (deceleration). The measured values are transmitted to the SGM and taken into account by the algorithm.

Note: In the event of a crash that triggers the airbags, the up-front sensors have to be replaced. The sensors might be damaged internally, even though no external damage is perceptible. Always comply with the instructions in the repair manual when replacing the up-front sensors.
