  As described above, in the present embodiment, the in-vehicle device 1 includes the communication module 15 that communicates with the server device 2, the GPS function unit 141 that detects position information, the clock unit 143 that counts time and date, and the GPS function unit 141. The unique information transmission unit 1151 transmits to the server device 2 unique information on boarding including the position information to be detected and the date and time counted by the clock unit 143, and the destination based on the traveling unique information transmitted by the unique information transmitting unit 1151 When a candidate is received from the server device 2, a display control unit 1152 displays the received destination candidate on the display unit 131, and an input for selecting a destination from the destination candidate displayed on the display unit 131 from the touch panel 132 And a decision control unit 1153 for accepting and deciding a destination. The server device 2 receives the communication unit 21 communicating with the in-vehicle device 1, the database 24 storing the unique information and the destination in association with each other, and the in-vehicle device 1 receiving the passenger's in-vehicle unique information The destination information collating unit 22 extracts a candidate of a destination from the database 24 based on the boarding specific information, and transmits the extracted candidate of the destination to the in-vehicle device 1.

  This enables foreign tourists to easily and efficiently set destinations. In particular, even if there are verbal problems between the driver and the passenger, the possibility of accurately transmitting the destination to the driver increases. That is, even if there are language problems between the driver and the passenger, the destination can be easily identified. In addition, since the server apparatus 2 extracts the destination candidate based on the inherent information at the time of boarding, for example, a passenger area x nationality x boarding time = people of the same nationality who boarded in the area went at that time Location can be extracted. Alternatively, a passenger area (main station, airport) x boarding time x nationality x purpose (Olympic) = a person of the nationality can extract the place where the competition took place on that day. Further, since the server device 2 in the data center extracts the candidate of the destination, the configuration of the in-vehicle device 1 in the vehicle can be simplified, and the processing can be improved.

  Further, the unique information transmission unit 1151 transmits to the server device 2 the getting-off unique information including the determined destination. The server device 2 includes the destination information registration unit 23 that registers the received alighting unique information with the getting-in unique information in the database 24 in response to the getting-off unique information from the in-vehicle device 1. As described above, accumulating data in the database 24 improves the accuracy of extracting destination candidates.

  In addition, the destination information check unit 22 adds the estimated arrival time or the estimated fare to the candidate of each destination, and the display control unit 1152 estimates the estimated arrival time or estimated added to the destination determined by the determination control unit 1153. Display the fare on the display unit 131. This allows the passenger to go to the destination with confidence.

  The whole or a part of the functions of the units included in the in-vehicle apparatus 1 or the server apparatus 2 in the above-described embodiment records a program for realizing these functions in a computer-readable recording medium, and this recording medium It may be realized by loading and executing a program recorded in the computer system. Here, the “computer system” includes an OS and hardware such as peripheral devices.

  The term "computer-readable recording medium" refers to a storage unit such as a flexible disk, a magneto-optical disk, a ROM, a portable medium such as a ROM or a CD-ROM, or a hard disk built in a computer system. Furthermore, “computer-readable recording medium” dynamically holds a program for a short time, like a communication line in the case of transmitting a program via a network such as the Internet or a communication line such as a telephone line. It may also include one that holds a program for a certain period of time, such as volatile memory in a computer system that becomes a server or client in that case. The program may be for realizing a part of the functions described above, or may be realized in combination with the program already recorded in the computer system.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, It is possible to add a various change in the range which does not deviate from the meaning of this invention.
