Integrated antenna for use with passive entry and ignition system

摘要

An alternative arrangement for a passive entry and ignition system for a vehicle is disclosed. The passive system uses an electronically coded card or "smart card' that electronically conveys identifying information to a single on board antenna. The single on board antenna is integrated into the roof panel of the vehicle using conventional wire or flat cable technology. The single antenna communicates to a vehicle control unit to enable actuation of various predetermined mechanical systems of a vehicle such as the vehicle entry system or the vehicle ignition system. In an alternative embodiment, the single on board antenna is integrated in an existing occupant detection mat located in the passenger seat of the vehicle.
