B-Pillar Sensor
The B-pillar airbag sensor consists of a longitudinal acceleration sensor and a transverse acceleration sensor.
The acceleration sensors measure both the acceleration and the deceleration in the X and Y directions. The resultant from the X and Y signals is the definitive factor in determining the direction of the impact.
The B-pillar airbag sensors serve the purpose of detecting head-on, side and rear-end collisions.
The B-pillar airbag sensors on the left and right are of identical design and are allocated by way of mechanical coding during installation.
