Delphi Automotive Systems announced that it is supplying a smart occupant-detection system for Jaguar and four Ford and Lincoln-Mercury models. The Passive Occupant Detection System (PODS) is the first weight-sensing system to reach the market, according to Delphi, and is standard equipment on the 2001 Jaguar XK sports car's Adaptive Restraint Technology System (ARTS).

PODS enables the "smart" deployment or suppression of passenger airbags. The weight-based system will help automakers meet the recently announced U.S. Federal Motor Vehicle Safety Standard (FMVSS) 208, which requires airbags that are more effective for a broader range of occupant weights. Beginning in 2004, 35% of each manufacturer's fleet sold in the U.S. must be equipped with advanced airbag systems, with the number increasing to nearly 100% by 2006.

PODS technology consists of a bladder-based weight-sensing technology mounted under the passenger seat cushion. Sophisticated occupant classification algorithms and extensive signal processing allow the vehicle airbag controller to variably deploy or suppress the passenger airbag, the latter significantly reducing repair costs. The technology consists of a silicone-fluid-filled bladder system produced by American Components Inc. (ACI), a pressure sensor under the seat cushion, and an electronic control unit for sensor data processing. Delphi and ACI applied bladder technology used for lumbar supports to the special PODS bladders.

Delphi is working with seat manufacturers, as well as other systems suppliers and vehicle manufacturers, to integrate PODS into vehicles. For example, Delphi is integrating PODS with another supplier's ultrasonic sensing system to provide additional passenger positioning measurements. While the ultrasonic sensors constantly monitor the presence and position of the front passenger, the PODS system detects the approximate weight of the occupant. In other applications, PODS will be integrated with a seat-belt-tension sensor to provide an airbag suppression system to meet the new federal guidelines.

Occupant-sensing products are anticipated to generate $3.6 billion or more in new revenue opportunities for automotive suppliers by 2006, according to Strategy Analytics Ltd.'s recent Automotive System Demand report. The report forecasts that the systems will grow in sales at a 70% compound annual rate over the next six years.
