Seat Occupation Detection (OC3): Notes

The seat occupancy detection consists of a seat occupancy mat  on which pressure-sensitive sensors are fitted. In addition, the seat occupancy mat has a hard-wire connection to an electronic evaluation unit.  The weight classification is based on evaluating the impression created by the person when taking their seat. The seat occupation detection cannot measure weights. Due to the activation of individual cells of the seat occupation mat, a weight class is determined by the electronic evaluation unit. The electronic evaluation unit sends cyclical information on the classification to the airbag control unit.
