TRW Releases Automatic Positioning Hybrid Tire Pressure Monitoring System

October 12, 2011, Hunsrück Test Center in Germany - TRW (Tex) Automotive Holding Co. (NYSE: TRW) developed a new generation of hybrid tire pressure monitoring system (TPMS) to provide automation with a combination of sensing technologies. GPS.

The system uses the basic direct tire pressure monitoring sensor mounted on the wheel to measure the air pressure and temperature in the tire, and combines the wheel speed sensor data of the vehicle ABS (anti-lock braking system) or ESC (electronic stability control) to provide an automatic positioning function. , inform the driver which tire(s) are in a low pressure state.

Martin Thoone, vice president of electronic engineering at TRW, said: "The advantage of the system is that it has an advanced automatic positioning system that eliminates the need for additional electronic hardware that was previously used for positioning sensors. In addition, receivers can be configured inside the vehicle to reduce the cost of the housing. This is an automatic positioning system that we currently use most economically."

Similar to TRW's existing direct tire pressure monitoring system (dTPMS), this technology consists of four basic sensors mounted on wheels to directly monitor a single tire pressure level, eliminating the need for additional sensor electronics for positioning. The receiver is usually fitted in the passenger compartment and uses the data from the tire pressure monitoring sensors and the vehicle ABS/ESC sensors to identify where the tire pressure is lacking.

Mr. Thoone concluded: “At present, TRW supplies its customers with non-direct tire pressure monitoring systems, but we believe that direct tire pressure monitoring is the best technical solution to ensure tire safety, reduce CO2 emissions and improve fuel consumption. Existing or potential mandatory regulations in Asia, the market for this product will continue to grow in the next five to ten years, and we will continue to develop the dTPMS technology portfolio to provide customers with more economical and applicable solutions.This release of the new hybrid tire pressure Monitoring technology is an important step in this direction."

TRW expects that the hybrid TPMS system will be put into mass production in 2013.
