PASSIVE ENTRY SYSTEM AND METHOD FOR A VEHICLE
First Claim
1. A method for determining the location of a remote transmitter positioned near a vehicle, the method comprising:
- transmitting a first polling sequence from the vehicle that includes at least a first and second polling signal, wherein the first polling signal is indicative of a first side of the vehicle, and the second polling signal is indicative of a second side of the vehicle;
receiving an acknowledgement signal from a remote transmitter in response to the first polling sequence;
determining if the remote transmitter is positioned near the first side or second side of the vehicle based upon the acknowledgement signal being in response to the first or second polling signals.

Abstract
A passive entry system and method for determining the location of a remote transmitter positioned near a vehicle. The system and method including a transmitter configured to transmit one or more polling sequences. The polling sequences including one or more polling signals indicative of a particular side and/or door of the vehicle. The system and method further including a receiver configured to receive an acknowledgement signal from a remote transmitter in response to one or more of the polling sequences. The system and method also including a controller configured to determine if the remote transmitter is positioned near the first side or second side of the vehicle based upon the acknowledgement signal being in response to the first or second polling sequence.
