The CPU 371 of the SS server 223 receives the on-vehicle device accumulation information from the on-vehicle device 211 via the access point 221. Then, the management server 230 collects vehicle acquisition information from the SS server 223 via the network 250 as needed or in batches.

  FIG. 3D is a diagram illustrating an appearance of the vehicle-mounted device 211. The vehicle-mounted device 211 is connected to the vehicle diagnosis connector 341, acquires and accumulates information from the engine computer or the like, and sends it to the access point 221 via the wireless LAN. The connection is completed simply by connecting the connector 342 of the vehicle-mounted device 211 to the vehicle diagnosis connector 341. On the rear surface 382 of the vehicle-mounted device 211, a lamp indicating that communication is being performed via a wireless LAN and a lamp indicating that vehicle acquisition information (OBD information) is being received from the vehicle are provided.

  FIG. 3E is a diagram illustrating a configuration of vehicle acquisition information acquired by the vehicle-mounted device 211 via the OBD-II interface. In FIG. 3E, PID391 is an identifier of vehicle acquisition information acquired via an OBD-II interface. The content 392 is the content of information identified by each PID 391. In FIG. 3E, 32 PIDs 391 are shown as part of the vehicle acquisition information. However, in OBD-II, the 32 pieces of information in FIG. 3E are the first 32 in the mode (Mode) 01 (HEX). It is only an individual. Details are disclosed in SAE (Society of Automotive Engineers) standard J / 1979.

  The vehicle acquisition information analysis unit 305 processes the vehicle acquisition information received from the vehicle from when the starter switch is turned on until it is turned off, and stores trip data 360 as on-vehicle device accumulation information for each time zone. Accumulate in the information database 306. That is, the trip data 360 is a summary of data between starter switches on and off in a fixed time unit. The in-vehicle device accumulated information transmission unit 308 transmits, via the communication control unit 309, the trip data 360 for each time zone, which is a wireless communication terminal (access point 221, SS server) provided outside the vehicle in order from the oldest time zone. 223). Thereby, it is possible to sequentially transmit data that is highly likely to be overwritten inside the vehicle-mounted device 211. On the other hand, trip data 360 for each time zone may be transmitted to the wireless communication terminals (access point 221 and SS server 223) provided outside the vehicle in order from the newest time zone. Thereby, the SS server 223 can acquire the latest data from the vehicle-mounted device 211 even if the communication time is short.

Is included.

  The acquisition date and time 362 includes the acquisition start date and time and the acquisition end date and time of the vehicle acquisition information, but trip data that crosses the time zone is divided for each time zone. For example, if the starter switch-on time is 11:06 and the starter switch-off time is 12:32, as in trip numbers 3603 and 3604, if the trip data is in units of one hour, the time starts from 11:06 The vehicle state information up to 11:59:59 becomes one trip data “3603”. The next trip data “3604” includes vehicle state information from 12:00 to 12:32. In addition, although each trip data is divided | segmented into 1 hour unit in any time slot | zone here, this invention is not limited to this. For example, the unit time may be changed in different time zones so that trip data is generated by dividing the daytime from 7:00 am to 12:00 pm in units of one hour and other times in units of two hours. Furthermore, it is good also as a structure which can set and change the unit time which produces | generates 1 trip data using the display etc. which were provided in the vehicle inside.

  Here, the various information 363 indicates the distance, the number of rapid accelerations, the number of rapid decelerations, the number of temporary stops, and the like, but the present invention is not limited to this. When the flag 364 is 1, it indicates that the continuous trip data is divided by the time zone. That is, in the example of this figure, the trip numbers 3603 and 3604 are originally continuous trip data, that is, the drivers are the same. On the other hand, trip numbers 3605, 3606, and 3607 are also originally trip data, that is, indicate that the drivers are the same.

  The in-vehicle device accumulation information database 306 uses the reader pointer 365 to store trip data “3601” to “3604” not transmitted by the communication control unit 309 and transmitted trip data “3605” to “3608”. Accumulated so that it can be identified.

  FIG. 3G is a diagram illustrating a situation in which the travel statistics information database 234 is generated using the trip data 360 for each time period in the management server 230. As shown in the figure, the insurance premium rate and the like can be obtained in detail based on the driving tendency of the driver and the like by statistically analyzing how many vehicles run for each time zone.

  FIG. 4A is a sequence diagram for explaining the flow of processing among the vehicle 210, the vehicle-mounted device 211, and the access point 221. First, when the vehicle-mounted device 211 is connected to the vehicle diagnosis connector 341 in step S401, power is supplied from the vehicle 210 in step S402, and its driving is started in step S403. Next, in step S404, various vehicle acquisition information is transmitted from the vehicle 210, and the vehicle-mounted device 211 receives various vehicle acquisition information in step S405. In step S406, the vehicle acquisition information analysis unit 305 of the vehicle-mounted device 211 analyzes the received vehicle acquisition information. In step S407, the vehicle acquisition information analysis unit 305 generates trip data 360 as the vehicle-mounted device storage information and stores it in the vehicle-mounted device storage information database 306. To do. While the starter switch is on, the processes in steps S404 to S407 are repeated. Next, when the starter switch is turned off in step S408, in step S409, the starter switch off is detected and the access point 221 is searched. Here, an access point 221 having an SSID (Servise Set Identifier) previously registered as an SS access point is found. If a plurality of access points 221 having the same SSID are found, the access point 221 with the strongest communication radio wave (high communication quality) is selected in step S411. In step S412, communication is established with the selected access point 221. Then, a data request is made from the SS server 223 to the vehicle-mounted device 211 in step S413. In step S414, the vehicle-mounted device 211 transmits the requested data to the SS server 223 via the access point 221, and in step S415, the SS server 223 receives the data.

  FIG. 4B is a diagram illustrating how data is requested and responded between the vehicle-mounted device 211 and the SS server 223. When the in-vehicle device completes connection with the access point 221, first, the in-vehicle device sends data ready for transmission to the SS server 223 (S 421). Next, eco-drive information as a part of the trip data 360 is requested from the SS server 223, and the vehicle-mounted device 211 responds to the request (S422). Next, failure diagnosis information as a part of the trip data 360 is requested from the SS server 223, and the vehicle-mounted device 211 responds to the request (S423). Next, battery information as part of the trip data 360 is requested from the SS server 223, and the vehicle-mounted device 211 responds to the request (S424). Next, date information as a part of trip data is requested from the SS server 223, and the vehicle-mounted device 211 responds to the request (S425). Next, date / time information is transmitted from the SS server 223 together with the date / time set request, and the vehicle-mounted device 211 sets the date / time information in response to the request (S426). Finally, an information acquisition completion notification is sent from the SS server 223 to the vehicle-mounted device 211 (S427).

  FIG. 4C is a diagram illustrating a flow of trip data generation and transmission processing performed by the vehicle acquisition information analysis unit 305. First, in step S441, the starter switch-on is detected. If the starter switch is turned on, the process proceeds to step S443, and vehicle information is acquired from the vehicle. Further, in step S445, the vehicle information is temporarily stored in the RAM 315. In step S447, it is determined whether a predetermined time has passed. Here, the predetermined time indicates a clear time such as 00:00:00. If such time has not passed, the process returns to step S441 to repeat the process.
