User identification system and vehicular portable device
First Claim
1. A user identification system comprising:
- an in-vehicle apparatus mounted to a vehicle used by a plurality of users; and
a vehicular portable device carried by a user acting as a driver among the users and associated with the in-vehicle apparatus,wherein;
the in-vehicle apparatus includesa vehicle apparatus-side communicator that communicates with the vehicular portable device;
the vehicular portable device includes;
a first communicator that communicates with the in-vehicle apparatus;
a second communicator that performs a short range wireless communication with portable terminals carried by the users;
a received signal strength detector that detects received signal strength of signals received by the second communicator from the portable terminals; and
a driver terminal determiner that, based on the received signal strength detected by the received signal strength detector, determines a driver terminal which is the portable terminal carried by the user acting as the driver;
the received signal strength detector detects the received signal strength of the signals received from the portable terminals at a plurality of time points; and
the driver terminal determiner determines as the driver terminal the portable terminal that provides a smallest degree of change of the received signal strength detected multiple times.

Abstract
A user identification system is provided, which includes an in-vehicle apparatus used by multiple users and a vehicular portable device carried by a user acting as a driver and associated with the in-vehicle apparatus. The vehicular portable device detects received signal strength of signals received from the portable terminals at multiple time points, and based on the received signal strength detected by the received signal strength detector, determines a driver terminal which is the portable terminal carried by the user acting as the driver. The vehicular portable device determines as the driver terminal the portable terminal that provides a smallest degree of change of the received signal strength detected multiple times.

14. A vehicular portable device associated with an in-vehicle apparatus mounted to a vehicle used by a plurality of users, the vehicular portable device comprising:
-
a first communicator that communicates with the in-vehicle apparatus; a second communicator that performs a short range wireless communication with portable terminals carried by the users; a received signal strength detector that detects received signal strength of signals received by the second communicator from the portable terminals; and a driver terminal determiner that, based on the received signal strength detected by the received signal strength detector, determines a driver terminal which is the portable terminal carried by the user acting as a driver, wherein the received signal strength detector detects the received signal strength of the signals received from the portable terminals at a plurality of time points, and wherein the driver terminal determiner determines the portable terminal providing a smallest degree of change of the received signal strength detected multiple times as the driver terminal.
