Apparatus and method for wireless device detection
First Claim
1. An apparatus for determining a location of a wireless device with respect to a vehicle, the apparatus comprising:
- an on-board vehicle controller for being operably coupled to a plurality of antennas in a vehicle and each antenna transmitting a first wireless signal to the wireless device to locate a primary antenna, the primary antenna being one of the plurality of antennas that transmitted the first wireless signal at a strongest signal strength, the controller being configured to;
store a first signal strength for a first control point that is positioned about the vehicle and away from the primary antenna;
determine the location of the wireless device based on a comparison of the first signal strength to the strongest signal strength;
determine that the wireless device is positioned proximate to the primary antenna if the strongest signal strength is greater than the first signal strength; and
store a second signal strength for a second control point positioned about the vehicle and away from a first antenna of the plurality of antennas, wherein the first antenna is different than the primary antenna.

Abstract
In at least one embodiment, an apparatus for determining a locating a wireless device with respect to a vehicle is provided. The apparatus comprises a controller for being operably coupled to a plurality of antennas in a vehicle and each antenna transmitting a first wireless signal to a wireless device to locate a primary antenna. The primary antenna being one of the plurality of antennas that transmitted the first wireless signal at a strongest signal strength. The controller being configured to store a first signal strength for a first control point that is positioned about the vehicle and away from the primary antenna. The controller being configured to determine the location of the wireless device based on a comparison of the first signal strength to the strongest signal strength.

5. A method for determining a location of a wireless device with respect to a vehicle, the method comprising:
-
transmitting from a plurality of antennas in the vehicle that is operably coupled to an on-board vehicle controller, a first wireless signal from each antenna to locate a primary antenna, the primary antenna being one of the plurality of antennas that transmitted the first wireless signal at a strongest signal strength; providing a first signal strength for a first control point that is positioned about the vehicle and away from the primary antenna; comparing the strongest signal strength to the first signal strength to determine the location of the wireless device; determining that the wireless device is positioned proximate to the primary antenna if the strongest signal strength is greater than the first signal strength; and providing a second signal strength for a second control point that is positioned about the vehicle and away from a first antenna of the plurality of antennas, wherein the first antenna is different than the primary antenna. - View Dependent Claims (6, 7, 8)

9. An apparatus for detecting a location of a wireless device with respect to a vehicle, the apparatus comprising:
-
a plurality of antennas for being positioned about the vehicle, each antenna for transmitting a first wireless signal to the wireless device; and an on-board vehicle controller for being operably coupled to the plurality of antennas and being configured to; receive a plurality of second wireless signals from the wireless device, each second wireless signal being indicative of a signal strength for each first wireless signal transmitted by each antenna; select a primary antenna from the plurality of antennas based on each second wireless signal, the primary antenna being indicative of the antenna that transmitted the first wireless signal at a strongest signal strength; store a first signal strength for a first control point positioned about the vehicle and away from the primary antenna; detect the location of the wireless device based on a comparison of the first signal strength to the strongest signal strength; detect that the location of the wireless device is positioned proximate to the primary antenna if the strongest signal strength is greater than the first signal strength; and store a second signal strength for a second control point positioned at a location about the vehicle and away from a first antenna of the plurality of antennas, wherein the first antenna is different than the primary antenna. - View Dependent Claims (10, 11, 12)
