Delphi's Adaptive Cruise Control Technology Featured On Cadillac XLR

KOKOMO, Ind., June 23 -- Delphi Corp.'s award- winning Forewarn(R) adaptive cruise control (ACC) technology continues to shine as it is featured on the Cadillac XLR at this week's 2004 Product Preview and GM Design and Technology Showcase in Milan, Mich.

"The Cadillac XLR is an excellent example of how luxury and innovation can combine to provide bold styling, contoured comfort and enhanced safety for the consumer," said Mary Schafer, business line executive for Chassis and Safety at Delphi Delco Electronics Systems. "Adaptive cruise control also brings a comfort and convenience feature to the driver that results in a more relaxed driving experience."

As the elegant XLR maneuvers effortlessly around the course, the ACC system measures the distance and relative speed of vehicles ahead using a sophisticated long-range radar sensor mounted behind the front bumper of the vehicle, cruising normally when the path ahead is clear and appropriately adjusting to traffic when necessary. The "cruise control with intelligence" is highly reliable, making more individual measurements on each horizontal radar scan than other systems. It can help the driver detect objects more than 100 meters ahead of the vehicle.

While the lane ahead is clear, the system will maintain the cruising speed set by the driver. When ACC detects slower moving traffic, the system will maintain a driver-selected headway (adjustable between 1.0 and 2.0 seconds) using throttle control and limited braking. The system also can detect if another vehicle crosses into the path from an adjacent lane and respond appropriately.

The radar-based technology provides superior performance in adverse weather conditions, compared to other laser-based systems available. ACC includes the ability to maintain a consistent and increased average following distance while providing the convenience of reduced need to manually accelerate or decelerate as the traffic becomes more congested.

In 2000, Delphi's Forewarn adaptive cruise control system received the Automotive News PACE (Premier Automotive Suppliers' Contribution to Excellence) Award. PACE recognizes standout automotive suppliers who have excelled in adapting and reinventing their companies or products to meet constantly increasing quality standards. The program also recognizes suppliers meeting the technology and service needs of their customers.

Delphi's ACC technology also is included in one of the largest field tests of its kind. In 1999, General Motors, Delphi Corporation, the U.S. Department of Transportation (DOT) and the University of Michigan Transportation Research Institute (UMTRI) became a part of an extensive research study to develop and evaluate collision warning technologies. The study includes a 10-month field test involving GM vehicles driven by 80 Michigan residents to test the latest in collision warning technology, including Delphi's adaptive cruise control and forward collision warning working with other technologies. The latest phase of the five-year program began in March.
