Embodiment Construction

[0043] Next, the present invention will be described based on specific examples. The position specifying system in the present invention is configured such that a portable terminal brought into the vehicle detects a signal sound emitted from a speaker installed in the vehicle compartment, and uses information related to the fact that the signal sound is detected by the portable terminal to identify the portable terminal. position in the car. In addition, it is a system configured to specify the mobile terminal held by the driver of the vehicle from among the mobile terminals whose positions in the vehicle interior have been specified. That is, it is a system configured to detect a mobile terminal brought into a vehicle interior, and to associate information related to the mobile terminal with vehicle information.

[0044] Hereinafter, a position specifying system according to an embodiment of the present invention will be described with reference to the drawings. Vehicles to...

Abstract

The invention identifies the location of a mobile terminal in a vehicle interior for mobile terminals brought into the interior of a vehicle. A location identification system comprising a mobile terminal and an information association device configured so as to be capable of mutual wireless communication, for which the information association device identifies the location of a mobile terminal in the vehicle interior by way of the mobile terminal brought into the interior of the vehicle detecting a signaling tone emitted from a speaker provided in the vehicle, is characterized in that: the mobile terminal comprises a means for storing detection information pertaining to the time the signaling tone was detected and a means for transmitting a first notification signal containing detection information; and the information association device comprises a means for causing each of a plurality of speakers to emit a signaling tone with a prescribed time gap therebetween, and a means for identifying the location of the mobile terminal in the vehicle interior using information pertaining to the speakers and the relative distance between the mobile terminal and a sound source of the signaling tone calculated on the basis of the prescribed time gap and the interval between the times when the signaling tones were detected.

Description

technical field [0001] The present invention relates to a position specifying system and method for specifying the position in the compartment of a portable terminal brought into the compartment of a vehicle. Background technique [0002] Various techniques are known for discriminating the presence or absence of a portable terminal brought into a vehicle interior. Furthermore, technologies for specifying the portable terminal held by the driver of the vehicle have been developed, and techniques for specifying the position of the portable terminal in the vehicle compartment or the seat on which the passenger holding the portable terminal is sitting are widely available. known. In most cases, it is configured as follows: an on-vehicle device capable of two-way communication with a portable terminal in the vehicle via an antenna installed in the vehicle determines whether or not there is a portable terminal in the vehicle based on data sent and received with the portable termi...
