Zusammenfassung:An indication system (10) for a vehicle (11) includes a radio frequency circuit (12) with a transponder (84) and an in-vehicle RF tagged element (18). The transponder (84) transmits a status request signal. A first radio frequency identification tag (84) is coupled to the in-vehicle RF tagged element (18). The tag (84) inductively generates a current status signal associated with the in-vehicle element (18) and in response to the status request signal. A method of tracking, identifying, and determining the presence and status of an in-vehicle RF tagged element (18) includes transmitting a status request signal. The status request signal is inductively received via multiple radio frequency identification tags (84, 86) that are associated with the in-vehicle RF tagged element (18). A current status signal is transmitted from the radio frequency identification tags (84, 86). An in-vehicle task is performed in response to the current status signal.
