The on-vehicle device detects stop position information indicating a stop position of the vehicle, receives the log information of the vehicle user from the portable device, generates behavior information at the time of getting out of the vehicle by relating the log information with the stop position information and transmits the behavior information at the time of getting out of the vehicle to a predetermined management server.

Description

  The present invention relates to a technique for investigating the behavior of a vehicle user when getting off.

  In recent years, car navigation devices that display the current position of a vehicle and search for a route have become widespread. Some of these car navigation devices transfer map data to a driver's mobile phone so that the mobile phone can be used as a navigation device for pedestrians when the driver gets off. In some cases, the driver removes the navigation device from the vehicle and carries it when getting off, and can be used as a navigation device for pedestrians. In any case, since the map data used in this case is data for car navigation, it may not be appropriate for pedestrians.

  For example, for car navigation data, the importance of information indicating the location of large buildings, parking lots, and gas stations, which are landmarks, is high, but these are less important for pedestrian data. The importance of data indicating the presence or absence of slopes, escalators, the location of entrances to facilities, etc. is high. That is, the map data for car navigation shows information on facilities along the roadway, but the data required by pedestrians often shows equipment on the sidewalk.

  Therefore, when using as a navigation device for pedestrians, pedestrian data must be prepared separately from vehicle data in the map data of the car navigation device.

  However, the data for pedestrians such as the presence or absence of stairs and the position of the doorway is enormous, and it is difficult to cover all roads. In addition, it is inefficient to include all of the enormous pedestrian data in advance in the map data for car navigation.

  Therefore, it is conceivable to prepare data for pedestrians by focusing on places where many people use.

  However, if a place where people gather is simply specified, the majority of people who gather at this place may come by train or the like without using a car. In this case, of course, few people use the car, and it is not worth adding information indicating this place to the map data of the car navigation device.

  For this reason, it is desired to be able to acquire information indicating a place where a person using a car often stops, that is, information that is highly valuable to be added to the map data of the car navigation device.

  Therefore, the present invention provides a technique for investigating the behavior of a vehicle user when getting off.

<Processing flow>
An explanation will be given of the behavior investigation method of the driver when getting off the vehicle executed by the car navigation device 1 and the portable device 2 in this system with reference to FIGS. FIG. 4 is a diagram showing a flow of processing in which the portable device collects log information when the driver gets off.

  First, when the driver stops the vehicle and operates the portable device 2 to select the survey start, the information processing unit 26 reads out and executes the application software from the storage unit 24, and starts the process of getting-off behavior survey ( S1). The information collecting means 71 has a counter (not shown) for measuring the timing of receiving information, and resets the counter value at the start. Note that the timing for starting the investigation is not limited to the one that the driver selects by directly operating the portable device 2, and the investigation may be started by detecting other state changes. For example, when the portable device 2 and the car navigation device 1 are connected by a cable or wireless communication and arrive at a place entered as a destination or stopover in the car navigation device 1, or when the vehicle engine is stopped, When the connection is canceled in order to take the portable device 2 out of the vehicle, the portable device 2 may detect this and start the investigation. In addition, a behavioral survey may be performed at all times, such as starting a survey when getting into a vehicle, and information acquired at a position different from the stop position of the car navigation device 1 may be extracted as a behavior when getting off.

  When the processing for getting off the vehicle is started, the information collecting means 71 determines whether an event has occurred (S2). If no event has occurred (S2, No), the value of the counter is used as an ink. Leeds (count up) (S3).

  Then, the information collecting means 71 determines whether or not the counter has reached a predetermined value, that is, whether or not a predetermined time has elapsed (S4). If the predetermined value has not been reached (S4, No), the process proceeds to step S2. If the predetermined value has been reached (S4, Yes), the counter is reset (S5) and information associated with the driver's action is acquired (S6). In addition, also when it determines with the predetermined | prescribed event having generate | occur | produced by step S2 (S2, Yes), the information accompanying a driver | operator's action is acquired (S6).

Here, the information accompanying the driver's action is information indicating a situation that changes depending on the driver's action, such as a signal from a GPS satellite, identification information assigned to a feature, a beacon signal from a beacon, etc. is there.

  For example, by periodically receiving a signal from a GPS satellite, it is possible to sequentially calculate the position information of the place moved by the driver's walking and to obtain the driver's travel route. The driver's position information may be obtained by the information collecting means 71, or signals from a plurality of GPS satellites received by the information collecting means 71 are sent to the car navigation device 1, and the car navigation device 1 or the management server 3 is sent. The position information may be calculated on the side.

  Also, when using services such as electronic money settlement of facilities (shopping malls, vending machines, etc.), network connection of hot spots, passing gates or ticket gates, it is determined that an event has occurred. You may receive it. As a result, identification information assigned to features such as shopping malls, hot spots, gates, and ticket gates is acquired, and information indicating where and what the driver has done is obtained. Further, when the beacon signal from the beacon can be received, it is received and recorded. As a result, information indicating that the driver has stopped at a position where the driver can receive a beacon sign signal (near the beacon installation position) is obtained. Therefore, position information can be collected by installing a beacon even in a place where GPS signals do not reach, such as indoors and underground malls. The timing of receiving these information may be received periodically or at a specific time, or a predetermined event occurs such as when electronic payment is made or when a beacon signal is received. It may be the case.

  After acquiring the information in step S6, the information collecting unit 71 determines whether or not the log collection is finished (S7), and if the driver selects the end by operating the operation unit 23 or logs information as described later. When a predetermined end condition is satisfied (S7, Yes), such as when it is transmitted to the car navigation device 1, the log collection processing is ended.

  On the other hand, if it is not the end, the information collecting means 71 returns the process to step S2 (S7, No) and repeats steps S2 to S7.

  FIG. 5 is a diagram illustrating a process flow when the car navigation device 1 transmits the stop action information to the management server 3.

  When the driver who has returned to the vehicle turns on the ignition of the vehicle, activates the car navigation device 1, and touches the portable device 2 to the reading unit of the car navigation device 1, the portable device 2 uses the NFC communication unit 25 to perform car navigation. A polling signal from the device 1 is detected, it is determined that communication is started (S11, Yes), log information is read from the storage unit 24, and is transmitted to the car navigation device 1 by NFC. That is, the car navigation apparatus 1 receives log information via the NFC communication unit 17 (S12).

  In the car navigation device 1 that has received the log information, the generation means 63 reads the stop position from the storage device 15 and adds it to the log information to generate the action information when getting off (S13). Here, the generation unit 63 may perform data thinning-out processing or additional information addition processing as described later.

Then, the transmission control means 64 of the car navigation device 1 transmits the getting-off action information generated by the generating means 63 to the predetermined management server 3 (S14).
The transmission control means (transmission means) 64 transmits the getting-off action information generated by the generation means 63 to a predetermined management server 3.

Thus, the portable terminal 2 carried by the driver collects log information, and based on this log information, the car navigation device 1 generates the behavior information at the time of getting off and transmits it to the management server, so that the driver at the time of getting off the vehicle. You can investigate how to act.

<Behavior information when getting off>
FIG. 6 is a diagram showing a format example of the action information when getting off. As shown in FIG. 6, the getting-off action information includes date and time, identification information, data type, data value, and remarks. Here, the identification information is unique information assigned to the portable device 2 and the car navigation device 1 so as to be identifiable. The data type is information indicating the type of data, such as whether it is a signal from a GPS satellite or an ID assigned to a feature. The data value is a specific value such as the latitude / longitude of the position information and the number assigned to the feature. Remarks indicate additional information such as incidental information.

  FIG. 7 is a diagram showing a specific example of action information when getting off. In FIG. 7, identification information 001 indicates the car navigation device 1, and 002 indicates the portable device 2. Further, when the data type is stop position information and GPS, the data value indicates east longitude and north latitude, for example, the values of No1 are 35 degrees 62 minutes 52.06 seconds east longitude and 139 degrees 76 minutes 98.36 seconds north latitude. It is.

  In the example of FIG. 7, records No. 1 and No. 75 indicate stop position information, and a record between them is log information collected by the mobile device 2 when getting off. That is, the driver who got off at the position indicated by No1 performs the actions indicated by the records No. 2 to No. 74 (partially omitted), and the driver who got off at the position indicated by No. 75 performed the actions indicated by the records No. 76 to No. 89. I understand.

  FIG. 7 shows an example in which position information is acquired when an event occurs and every predetermined time (30 seconds).

  The generation means 63 of the car navigation device 1 may include all of the acquired log information in the getting-off action information, but may generate the getting-off action information by thinning out the log information according to a predetermined condition. For example, records whose latitude and longitude change are within a predetermined range (within 5 seconds in the example of FIG. 8) are thinned out. FIG. 8 shows an example of the getting-off action information after the thinning process.

  Further, the generation means 63 refers to the map information in the storage device 15, obtains supplementary information such as the name of the feature corresponding to the position indicated by the log information, and writes it in the remarks column of each record. Similarly, if there is a database of incidental information corresponding to the facility ID, the incidental information corresponding to the facility ID is written in the remarks column of each record. The incidental information corresponding to the facility ID may be obtained by the management server 3.

  And the production | generation means 63 may produce | generate the action information at the time of getting off by thinning out the record with which supplementary information overlaps. FIG. 9 shows an example of the action information at the time of getting off after thinning out records having overlapping information.

  As described above, by performing the thinning process and thinning out redundant records, it is possible to suppress the data amount of the behavior information at the time of getting off to be transmitted to the management server 3.

<Operation and effect of this embodiment>
According to this embodiment, the portable device 2 carried by the driver records the position and event information relating to the driver at a predetermined timing, and the portable device 2 records the information when the driver returns to the vehicle. The data is passed to the car navigation device 1, and the car navigation device 1 generates the behavior information when the driver gets out of the vehicle from the information on the stop position of the vehicle and the record, and sends the behavior information when the vehicle gets off to the management server. Thereby, this system 10 can investigate appropriately a driver's action of what kind of action a driver often performs when getting off.

Thereby, for example, map data can be transferred from the car navigation device 1 to the driver's mobile phone, and data useful as navigation for pedestrians can be accurately identified.
