Delphi is ready to help achieve NHTSA tire pressure monitoring system requirement

TROY, Mich., May 9 -- Delphi Corp.'s patented integration technology for its tire pressure monitoring system offers a unique way of using a common receiver to integrate the tire pressure sensor and another vehicle function such as keyless entry. Delphi's integration system will help vehicle makers comply with new requirements recently announced by the National Highway Traffic Safety Administration's (NHTSA). The new regulations require all new passenger vehicles to have a system to warn drivers of under inflated tires by 2008.

"This technology is great news for vehicle safety and it also has the potential to contribute to reduced fuel consumption," said Jeff Owens, president of Delphi Electronics & Safety. "We are excited about the opportunity to provide our technology to vehicle manufacturers as well as licenses to other parts suppliers to help vehicle makers meet specifications put forth in this new regulation."

Pressure sensors are mounted in a tire via the tire valve to sense the pressure condition. The tire pressure sensor sends a low frequency signal to transmit the information to a receiver in the vehicle. Delphi's patent enables the integration of tire pressure sensors with electronics already present in the vehicle so that information can then be displayed and communicated to the driver.

The sensor can also work with the vehicle's remote keyless entry (RKE) system using the same RF (radio frequency) modulation as the RKE system. The RKE system can receive the signal from the sensor, providing data such as tire pressure.

The unique technology benefits manufacturers and consumers by eliminating the need for a separate receiver, lowering the overall cost of the system.

"Delphi's technology offers an easy and cost-effective way for automakers to comply with the new NHTSA regulations," said Owens. "It minimizes both design and implementation cost."

Besides reducing the probability of tire-related incidents, tire pressure monitoring can also increase fuel economy and tire life.

"With oil at more than $50 a barrel and rising, the fuel savings benefits will increase the attractiveness of this system to drivers and vehicle makers," Owens said.

The Chevrolet Corvette, which has developed a track record for leading the way in applying advanced technologies, was the first vehicle to offer a tire pressure monitoring system in 1997 using Delphi technology. Delphi has also provided its system in the Cadillac CTS and SRX.

Delphi's system uses the existing antenna elements for the AM/FM/RFA antenna system embedded in the rear window or side glass of the vehicles and displays the tire pressure information on the driver information center.

At present, Delphi is set to put its tire pressure integration system on two future vehicle platforms and is licensing its technology to other auto suppliers. For more information on Delphi, contact http://www.delphi.com/ .
