Commercial Passenger Occupant Detection System

Delphi Automotive PLCelphi PODS(Passive Occupant Detection System) weight-sensing system enables vehicle manufacturers to improve the effectiveness of airbag protection through smart deployment or suppression of the passenger's airbag.

PODS technology consists of a bladder-based weight-sensing technology mounted under the passenger seat cushion. Using occupant classification algorithms and extensive signal processing, it allows the vehicle airbag controller to variably deploy or suppress the passenger airbag. Designed to measure the occupants loading force on the vehicle's seat, the system classifies the occupant according to weight, and provides the information to the airbag controller based on the occupant's characteristics, an important factor in determining whether, and to what extent, the airbag should be deployed.

The passive system requires no interaction or involvement by the driver or passengers to achieve the appropriate deployment decision. In addition, the system is nearly universal to all seat types without affecting seat crashworthiness.

The PODS technology consists of a silicone fluid-filled bladder weight system, a pressure sensor mounted under the seat cushion, and an electronics control unit for sensor data processing.
