(Operation of vehicle position management system 100 during parking operation)
Next, the operation of the vehicle position management system 100 when the user parks the vehicle will be described with reference to FIG. FIG. 3 assumes a scene where the user arrives at the destination and parks the vehicle. As an example, the destination facility has a three-story multi-level parking lot (so-called three-tier four-tier parking lot) that can also be parked on the roof, and the user places a vehicle on the second floor of the parking lot. It shall be parked.

  When the user stops the vehicle in the empty parking space on the second floor of the parking lot, the user puts the shift lever into the parking position and turns off the ignition power (step U1). In step U1, when a signal indicating that the ignition power is turned off is input to the vehicle-side control unit 15 via the external I / F 12, the parking detection unit 15C detects that the vehicle is parked. (Step C1).

  Then, the transmission processing unit 15S generates transmission position information in which a vehicle identifier is added to the vehicle position detected by the position detection unit 15B, and outputs the transmission position information to the vehicle side communication unit 11. And the vehicle side communication part 11 transmits this position information for transmission to the server 2 (step C2). Thereafter, when the reception processing unit 15R receives a response signal indicating successful reception from the server 2 and the transmission processing of the transmission position information is completed, the power of the in-vehicle device 1 is turned off (step C3).

  When receiving the transmission position information transmitted by the in-vehicle device 1 (step S1), the reception processing unit 22R of the server 2 refers to the user DB 23 and specifies a user corresponding to the vehicle identifier included in the transmission position information. . Then, the vehicle position information including the hierarchy information specified by the hierarchy specifying unit 22A based on the vehicle position information included in the transmission position information is stored in the user DB 23 so as to correspond to the corresponding user (step S2). For example, in this case, the vehicle position information includes, in addition to latitude, longitude, and altitude, hierarchical information and the position of the vehicle (such as a parking space number) in the hierarchy where the vehicle is parked.

  Here, the process in which the hierarchy specifying unit 22A specifies the hierarchy in which the vehicle is parked in the facility will be described with reference to FIG. FIG. 4 shows facility data related to a facility where the vehicle is parked, which is specified based on the latitude and longitude included in the vehicle position information. The hierarchy specifying unit 22A can obtain the height of each hierarchy from the ground by referring to the facility data. Here, as shown in FIG. 4, the height of the second floor is 5 m, the height of the third floor is 10 m, and the height of the rooftop is 15 m.

  Here, the level specifying unit 22A specifies the floor on which the vehicle is parked by comparing the floor height of each level with the height of the vehicle position from the ground. For example, as shown in FIG. 4, when the height of the vehicle position from the ground is 6 m, the vehicle is parked on the second floor because it is higher than the second floor and lower than the third floor. It is determined that

  Note that the height of the vehicle position from the ground may be determined based on the information about the height included in the vehicle position information, that is, here based on the signal received by the GNSS receiver. When the information about the height described as the vehicle position information is expressed in altitude as in this embodiment, the height of the vehicle position from the ground is the terrain included in the map data. What is necessary is just to calculate using data. Of course, when the information about the height included in the vehicle position information is expressed by the height from the ground, the terrain data need not be used.

  In the above processing, when the parking detection unit 15C detects that the vehicle is parked, the transmission processing unit 15S automatically transmits the transmission position information including the vehicle position information to the server 2, and the server 2 The location information is stored in association with the user. At this time, the in-vehicle device 1 and the mobile terminal 3 do not perform communication for transmitting the vehicle position to the mobile terminal 3.

  Therefore, in order to register the vehicle position in the portable terminal 3, it is not necessary to activate an application installed in the portable terminal 3, and it is not necessary to activate the application in advance.

(Operation of vehicle position management system 100 at the time of position confirmation)
Next, the operation of the vehicle position management system 100 when the user confirms the vehicle position with the portable terminal 3 will be described with reference to FIG.

  First, the user takes out the mobile terminal 3 and performs an operation (such as a touch operation on the switch 34) for starting an application (step U2). Based on the user operation in step U2, the mobile terminal 3 activates the application (step M1).

  Then, when the application is activated, the transmission processing unit 35S transmits a vehicle position information request for requesting to transmit the vehicle position information to the server 2 via the portable device side communication unit 31 (step M2). This vehicle position information request includes a user identifier stored in a nonvolatile memory included in the mobile terminal 3.

  When the reception processing unit 22R of the server 2 receives the vehicle position information request transmitted from the mobile terminal 3 (step S3), the data management unit 22B displays the vehicle position information corresponding to the user identifier included in the vehicle position information request. Read from the user DB 23 (step S4). The vehicle position information transmitted at this time includes the hierarchy information of the vehicle specified by the hierarchy specifying unit 22A in addition to the latitude and longitude as described above.

  And the transmission process part 22S reads the data for map image drawing required in order to draw a vehicle map image from map data. The range of data to be read out from the map data as map image drawing data (such as a floor map of the corresponding facility) may be determined based on the vehicle position information. The transmission processing unit 22S generates vehicle position related information including vehicle position information and map image drawing data, and transmits the vehicle position related information to the mobile terminal 3 via the server side communication unit 21 (step S5).

  When the reception processing unit 35R included in the portable terminal 3 receives the vehicle position related information transmitted by the server 2 via the portable device side communication unit 31 (step M3), the reception processing unit 35R passes the vehicle position related information to the display processing unit 35B. .

  The display processing unit 35B generates a vehicle map image based on the vehicle position information and the map image drawing data included in the vehicle position related information, and displays the vehicle map image on the display 33 (step M4). An example of this vehicle map image is shown in FIG. In FIG. 6, a star-shaped mark 51 represents the position of the vehicle, and an isosceles triangle mark 52 represents the position and orientation of the mobile terminal 3 (that is, the user). A window 53 shown at the lower left of the screen represents the direction and distance in which the vehicle is present to the user.

  The user can confirm the position of the vehicle by looking at the vehicle map image (step U3). FIG. 6 is an example of a vehicle map image when the current position of the mobile terminal 3 can be used. As described above, as another form, when the mobile terminal 3 does not include the GNSS receiver 32 and the current position of the mobile terminal 3 cannot be acquired, a map including the position of the vehicle and the surrounding map is displayed. Just do it. Moreover, you may alert | report a vehicle position to a user not only by a map image but by a text. The screen of the display 33 displaying information including the position of the vehicle such as a vehicle map image corresponds to the position confirmation screen described in the claims.

(Summary of embodiment)
In the above configuration, when the parking detection unit 15C detects that the vehicle is parked (step C1), the transmission processing unit 15S automatically transmits the transmission position information including the vehicle position information to the server 2 (step C2). ) The server 2 stores the vehicle position information included in the transmission position information in association with the user (step S2). At this time, the in-vehicle device 1 and the mobile terminal 3 do not perform communication for transmitting vehicle position information to the mobile terminal 3.

  Therefore, the user need not activate an application installed in the mobile terminal 3 in order to register the vehicle position in the mobile terminal 3 during the parking operation, and needs to activate the application in advance. Does not occur. Since it is not necessary to activate the application in advance, power consumption of the mobile terminal 3 can be suppressed.

  Then, when receiving an operation for confirming the position of the vehicle from the user (step U2), the portable terminal 3 acquires vehicle position information from the server 2 (steps M2, M3), and displays the vehicle map image on the display 33. (Step M4). The user can confirm the position of the vehicle by looking at the vehicle map image.

  In the present embodiment, the display processing unit 35B is configured to generate the vehicle map image based on the map image drawing data received from the server 2, but the present invention is not limited to this. When the mobile terminal 3 includes the map DB 24, the map image drawing data may be read from the map DB 24 included in the mobile terminal 3 itself based on the received vehicle position information to generate a vehicle map image. In this case, the server 2 does not need to transmit the map image drawing data in step S5, and may transmit the vehicle position information.

  Moreover, when the portable terminal 3 is equipped with map DB24, you may implement the process which pinpoints the hierarchy in which the vehicle is parked in the portable device side control part 35. FIG. That is, the hierarchy specifying unit 22A may be provided in the portable device-side control unit 35.

  Similarly, when the in-vehicle device 1 includes the map DB 24, the vehicle-side control unit 15 may perform a process of specifying the level where the vehicle is parked. That is, the hierarchy specifying unit 22A may be provided in the vehicle-side control unit 15. In this case, the vehicle position information included in the transmission position information may be represented by the latitude, longitude, and parked hierarchy.

  In the present embodiment, the user identifier stored in the nonvolatile memory is read out and the vehicle position information request is transmitted. However, the present invention is not limited to this. When a vehicle location information request is made without storing the user identifier, the user may be requested to input the user identifier, and the vehicle location information request may be transmitted using the user identifier input by the user. The portable device side control unit 35 may acquire a user identifier input by the user via the operation reception unit 35A.

  Furthermore, although it was set as the structure which the user can confirm a vehicle position with the portable terminal 3 by starting an application above, it is not restricted to this. It is good also as a structure which can confirm a vehicle position by accessing the predetermined | prescribed web page provided on the internet, and inputting a user's own user identifier, without going through an application. Even with such a configuration, it is not necessary to operate the portable terminal 3 in order to register the vehicle position when parking.

  Moreover, although it was set as the structure which includes the position of a height direction, such as parked on what floor, as vehicle position information above, it is not restricted to this. The vehicle position information may be only the latitude and longitude, and the position confirmation screen may display information determined from the latitude and longitude without including information on the height (that is, hierarchical information).

  Moreover, although the vehicle side communication part 11 and the server side communication part 21 showed the structure which implements communication not via the portable terminal 3 above, it is not restricted to this. The in-vehicle device 1 and the mobile terminal 3 may perform communication according to a predetermined communication standard, and the communication between the in-vehicle device 1 and the server 2 may be performed using the wireless communication function of the mobile terminal 3.

  The communication between the in-vehicle device 1 and the portable terminal 3 may be performed by wireless communication according to a short-range wireless communication standard such as Bluetooth (registered trademark), a wireless LAN standard such as IEEE 802.11, or the like. It is good also as a structure performed by wired communications, such as communication. Even in this case, the vehicle position detected by the position detection unit 15B can be transmitted to the server 2 without starting the application installed in the portable terminal 3.

(Modification 1)
In the above-described embodiment, as shown in FIG. 4, the level specifying unit 22A vehicle is parked based on the height from the ground of the vehicle determined based on the signal input from the GNSS receiver and the facility data. Although the configuration is such that the hierarchy is specified, the present invention is not limited to this.

  For example, if a terminal (referred to as a network spot) 4 (refer to FIG. 7) that provides floor information to the vehicle-mounted device 1 by wireless communication is installed in each level of a parking lot, the network spot 4 What is necessary is just to specify a hierarchy using the acquired floor information. In this case, the hierarchy specifying unit 22A has a configuration included in the in-vehicle device 1. For example, the vehicle location management system 100 in the first modification may be operated as follows.

  The vehicle-side communication unit 11 and the network spot 4 are configured to be able to communicate with each other by, for example, a wireless LAN. When the vehicle-mounted device 1 enters the communication range of the network spot 4, the vehicle-mounted device 1 automatically The floor information is acquired from the network spot 4.

  The floor information distributed by the network spot 4 includes information indicating the floor number (that is, hierarchy information). The reception processing unit 15R that receives the floor information distributed from the network spot 4 via the vehicle-side communication unit 11 corresponds to the vehicle-side reception processing unit described in the claims.

  And the vehicle-mounted apparatus 1 transmits the vehicle position information including the hierarchy information acquired from the network spot 4 and the latitude and longitude detected by the position detection unit 15B to the server 2 as the transmission position information together with the vehicle identifier.

  Here, the transmission position information may be transmitted directly from the in-vehicle device 1 to the server 2 as indicated by a one-dot chain line in FIG. 7, or via the network spot 4 as indicated by a two-dot chain line in FIG. May be transmitted to the server 2.

(Modification 2)
Further, as shown in FIG. 8, the hierarchy specifying unit 22A may display an option for the user to input what floor is currently on the display 13, and may acquire hierarchy information based on the input from the user. . In the case of the second modification, the in-vehicle device 1 includes the hierarchy specifying unit 22A.

  For example, the hierarchy specifying unit 22A causes the display 13 to display the screen illustrated in FIG. 8 when the parking detection unit 15C detects that the vehicle is parked. The screen shown in FIG. 8 displays options for selecting a hierarchy, and guides the user to select a corresponding hierarchy. When the switch 14 is a touch panel type switch, the hierarchy information is acquired by specifying the hierarchy selected by the user from the position where the user touched the touch panel.

  Then, the vehicle position information including the hierarchy information acquired based on the user operation and the latitude and longitude detected by the position detection unit 15B may be transmitted to the server 2 as the transmission position information together with the vehicle identifier.

  According to such a configuration, even when the GNSS receiver included in the vehicle cannot receive the GNSS radio wave and the network spot 4 described in Modification 1 cannot be used, the hierarchy specifying unit 22A acquires the hierarchy information. I can do things.
