Location

The pressure sensors are located behind the respective door trim.

Task

To detect a side impact in the door area, the pressure sensors measure the air pressure values inside the doors. If the air pressure value increases significantly in one door (e.g. when the door skin is pressed in from outside), the restraint systems control unit (N2/7) triggers the respective sidebag or windowbag in the impact area.

Scope of tasks

After a successful self-test, the pressure sensors confirm success by transmitting a signal to the restraint systems control unit.
Upon request of the restraint systems control unit, the measuring range and the sensitivity of the pressure sensors are transmitted, and the system checks whether they match the programmed equipment. The production data can be output via STAR DIAGNOSIS.
