Integrated passive entry transmitter/receiver
First Claim
1. A portable personal convenience device carried by a person having access to a transportation vehicle comprising:
- personal convenience means for performing a non-transportation related convenience function, said personal convenience means further including an expansion slot; and
a passive entry device integrated within said personal convenience means and adapted to interact with said transportation vehicle for passively gaining access thereto, said passive entry device comprising;
a receiver for receiving an interrogating signal from an electronic control module in a vehicle;
a transmitter for broadcasting a response signal to said electronic control module; and
a controller for controlling the transfer of said response signal to said electronic control module in response to a validity of said interrogating signal;
an interchangeable plug-in module received in said expansion slot for receiving electrical power from said personal convenience means, wherein said plug-in module includes an algorithm for performing passive-entry vehicle functions, and wherein said plug-in module includes a plurality of identification codes and messaging protocols for accessing more than one transportation vehicle.

7. A method of operating a passive entry system using a portable personal convenience device for gaining access to a specific transportation vehicle, said method comprising the steps of:
-
providing an expansion slot and an interchangeable plug-in module in said portable personal convenience device, said expansion slot receiving said interchangeable plug-in module which receives electrical power from said portable personal convenience device, said plug-in module including an algorithm for performing passive-entry vehicle functions, said plug-in module further including a plurality of identification codes and messaging protocols for accessing more than one transportation vehicle; concealing a remote passive entry device within a personal convenience means housing; detecting a user request for a passive entry function to said transportation vehicle; broadcasting an interrogation signal to a broadcast region exterior to said transportation vehicle; receiving said interrogation signal in said portable personal convenience device; determining whether said interrogation signal is valid; broadcasting a response signal to an electronic control module in response to said validity of said interrogation signal; determining whether said response signal is valid; and transmitting a control signal to a vehicle safety mechanism for activating one of a plurality of passive entry functions to said vehicle in response to said validity of said response signal. - View Dependent Claims (8, 9, 10, 11)
