SYSTEM AND METHOD FOR DETECTING A LOCATION OF A WIRELESS DEVICE
First Claim
1. A vehicle system comprising:
- a portable device configured to transmit a first wireless signal; and
a plurality of base stations for being positioned about a vehicle, each base station being configured to receive the first wireless signal, wherein a main base station of the plurality of base stations is configured to;
determine a first final position in response to each of the plurality of base stations successfully receiving the first wireless signal;
monitor for subsequent receipt of a second wireless signal indicative of motion data of the portable device at each of the plurality of base stations after determining the first final position;
determine that a first base station has received the second wireless signal;
determine that a second base station has not successfully received the second wireless signal; and
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.

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.

10. An apparatus comprising:
-
a plurality of base stations for being positioned about a vehicle, each base station being configured to receive a first wireless signal from a portable wireless device, wherein a main base station of the plurality of base stations is configured to; determine a first final position in response to each of the plurality of base stations successfully receiving the first wireless signal; monitor for subsequent receipt of a second wireless signal indicative of acceleration data and orientation data of the portable device at each of the plurality of base stations after determining the first final position; determine that a first base station has received the second wireless signal; determine that a second base station has not successfully received the second wireless signal; and determine a second final position of the portable device using the first final position, and the acceleration data and the orientation data of the second wireless signal as received at the first base station, after determining that the second base station has not successfully received the second wireless signal. - View Dependent Claims (11, 12, 13, 14, 15)
