SYSTEM OF PASSIVE KEYLESS WITH A TIRE PRESSURE MONITORING FOR A VEHICLE

摘要

A PKE(Passive Keyless Entry) system equipped with a TPMS(Tire Pressure Monitoring System) for a vehicle is provided to integrate a base station of a PKE, an ECU of the TPMS, an LF antenna, and a driver, and to use an integrated communication unit in order to drive the display of a TPMS. A PKE system includes an ECU(Electronic Control Unit)(10), a transponder(30), and a rim sensor(50). The ECU transmits/receives a variety of authentication signals and controls a base station of an antenna(15) and a TPMS. The transponder transmits/receives a variety of authentication signals. The transponder includes a display circuit. The rim sensor measures a temperature and a pressure of a tire. The rim sensor modulates a low-frequency signal to make communication.
