System and method for vehicle passive entry having inside/outside detection
First Claim
1. In a passive entry system for a vehicle, the passive entry system including a remote transceiver, a system for detecting a location of the remote transceiver relative to the vehicle comprising:
- an exterior vehicle antenna for use in transmitting a first signal for receipt by the remote transceiver;
an interior vehicle antenna for use in transmitting a second signal for receipt by the remote transceiver; and
a controller on board the remote transceiver for determining a signal strength of the first signal, determining a signal strength of the second signal, and determining whether the remote transceiver is located inside or outside the vehicle based on the signal strengths of the first and second signals.

Abstract
In a vehicle passive entry system including a remote transceiver, a system and method for detecting the location of the remote transceiver relative to the vehicle. An exterior vehicle antenna is provided for use in transmitting a first signal for receipt by the remote transceiver, and an interior vehicle antenna is provided for use in transmitting a second signal for receipt by the remote transceiver. A controller is provided on board the remote transceiver for determining a signal strength of the first signal, determining a signal strength of the second signal, and determining whether the remote transceiver is located inside or outside the vehicle based on the signal strengths of the first and second signals.
