The company expects launch the integrated system in 2012 for a 2013 model year vehicle. According to TRW Automotive, the RKE will receive the transmitted commands by a single smart receiver/ECU which will process information from RKE fobs and also the temperature and pressure signals sent from the transmitters located in TPMS sensor units in each individual tire.
In addition, the integrated ECU decodes the signal to activate the lock/unlock function for vehicle doors and the trunk, and provides tire pressure warning information to the driver in the same way as conventional RKE and TPMS receivers.
Martin Thoone, vice president of Global Electronics Engineering, said: "The integration of RKE and TPMS is another example of TRW's drive toward enhancing value and performance through electronics integration.
"This system simplifies the electronics architecture by eliminating the need for separate receivers for these two systems - we can maintain the performance characteristics while using less space and reducing system weight and wiring complexity, leading to lower material and assembly costs."
