SYSTEM AND METHOD FOR MONITORING THE LOCATION OF A COMMUNICATION DEVICE IN A VEHICLE BASED ON SIGNAL STRENGTH
First Claim
1. A system for locating a personal communication device (PCD) in a vehicle, the system comprising:
- a controller for being operably coupled to a first antenna positioned in a driver zone and a second antenna positioned in a passenger zone, the controller being configured to;
receive a first signal from the PCD at the first antenna;
measure a signal strength of the first signal received at the first antenna to generate a first signal strength value;
receive the first signal from the PCD at the second antenna;
measure a signal strength of the first signal received at the second antenna to generate a second signal strength value;
determine whether the first signal at the first antenna and the second signal at the second antenna are received within a predetermined amount of time of one another;
compare the first signal strength value to the second signal strength value if the first signal at the first antenna and the second signal at the second antenna are received within the predetermined amount of time; and
determine whether the PCD is in one of the driver zone and the passenger zone based on the comparison of the first signal strength value to the second signal strength value.

Abstract
A system for locating a personal communication device (PCD) in a vehicle is provided. A controller is configured to receive a first signal from the PCD at a first antenna in a driver zone and to generate a first signal strength value for the first signal. The controller is configured to receive the first signal from the PCD at the second antenna and to generate a second signal strength value for the first signal. The controller is configured to determine whether the first signal at the first antenna and the second signal at the second antenna are received within a predetermined amount of time of one another and to compare the first signal strength value to the second signal strength value if the first signal at the first antenna and the second signal at the second antenna are received within the predetermined amount of time.
