TRW has launched its first integrated remote keyless entry (RKE) and direct tire-pressure-monitoring system (TPMS) with a major Japanese vehicle manufacturer. "Integrating RKE and TPMS can offer enhanced value and performance," said Ken Kaiser, Vice President, Global Electronics Engineering, TRW. "By eliminating the need for separate receivers for the two systems, we can maintain performance characteristics, use less space, reduce system weight and wiring complexity, and ultimately lower material and assembly costs." The system is also leading the industry in reducing risks associated with RF interference, the company says, by using multiple frequencies. This technology change is transparent to vehicle owners as there is no discernible change to the RKE key fob layout or performance. The transmitted commands are received by a single smart receiver/ECU that processes information from the RKE fobs and the temperature and pressure signals sent from the transmitters located in the TPMS sensor units in each tire.
