Vehicle makers now have a choice -- vehicle-by-vehicle -- when selecting a tire pressure monitoring system, and TRW Automotive is in a distinctive position to provide both direct or indirect types of systems.

Long before the White House Office of Management and Budget's (OMB) direction to U.S. National Highway Traffic Safety Administration (NHTSA) to reconsider both direct and indirect pressure sensing options, TRW Automotive was leading the way in the development of direct and indirect tire pressure monitoring systems (TPMS).

"With the capability to produce a direct or indirect system, TRW can effectively cover the needs of the entire vehicle spectrum, from small cars to large trucks and SUVs, and from less expensive models to luxury cars," said Doug Campbell, vice president, engineering, Occupant Safety Systems, TRW Automotive. "For example, indirect systems can be offered at minimal cost in the case of vehicles already equipped with four-wheel Anti-lock braking systems, while direct monitoring systems can communicate a range of accurate information to the driver through telematic readouts in higher-end cars."

Generally, the benefits of tire pressure monitoring and correct tire pressure include improved vehicle dynamics behavior, fuel saving, longer tire life and a significant reduction in the number of tire blowouts.

As the world's third largest producer of anti-lock braking systems and North America's leading manufacturer, TRW Automotive can effectively utilize its expertise with ABS systems to indirectly monitor the air pressure in tires. Indirect TPMS technology is not new at TRW. Since August 2000, TRW has included indirect TPMS algorithms in its ABS production system for the Ford Windstar.

TRW, in cooperation with Michelin, is developing the "EnTire Solution," an advanced direct TPMS which will be equipped in vehicles by mid 2003. This system delivers accurate readouts, has the ability to indicate what tire is under-inflated, front or rear, left or right, and offers other major benefits to the driver. Using predictive algorithms, the driver can be warned that there will be a low-pressure tire problem in the near future. This warning can alert the driver to take action before getting on a long stretch of highway. False alarms are another concern that can cause a true low-pressure warning to be ignored even by the most conscientious driver. TRW Automotive and Michelin have incorporated such advanced monitoring algorithms into the EnTire Solution TPMS that detect slow leaks, yet also account for driver habits and environmental conditions to eliminate false warnings.

TRW Automotive is a leader in active and passive safety systems for the global automotive industry. Products include integrated vehicle control and driver assist systems, braking systems, steering systems, suspension systems, occupant safety systems, electronics, engine valves, fastening systems and aftermarket replacement parts. TRW Inc. (NYSE: TRW) provides advanced technology products and services to the automotive, aerospace and information technology markets. The company's 2001 sales were $16.4 billion (USD).
