Abstract
A vehicle system and method is provided for detecting the location of a portable wireless device. The vehicle system includes the portable device and a plurality of base stations positioned about a vehicle. The portable device is configured to transmit a first wireless signal and a second wireless signal indicative of motion data of the portable device. A main base station of the plurality of base stations is configured to determine a first final position of the portable device in response to each of the plurality of base stations successfully receiving the first wireless signal. The main base station is further configured to determine a second final position of the portable device using the first final position and the motion data of the second wireless signal as received at the first base station and after determining that the second base station has not successfully received the second wireless signal.
