Door Pressure Sensor
The airbag sensors in the front doors serve the purpose of verifying the plausibility of the acceleration signals from the B-pillar airbag sensors and the central sensor during side crash detection.
The airbag sensors are situated in the inner panels of the front doors and measure the increase in pressure in the event of a side-on impact.
In the event of a side-on impact with the door, the outer door panel is pressed inward, thus reducing the inner door space and increasing the pressure. This change in pressure is measured by the airbag sensors.
The airbag sensor also includes an electronic module, in addition to the pressure sensor, which digitizes the pressure values and transmits them cyclically to the Crash Safety Module. The data is transmitted in the same way as the B-pillar airbag sensors.
The pressure values are evaluated in the crash safety module.
