Description

  The present invention relates to a navigation device, a navigation method, and a navigation program.

  As a system using Dedicated Short Range Communications, an automatic toll collection system called ETC (registered trademark) system has been put to practical use. An ETC system widely spread in Japan includes an antenna device for performing road-to-vehicle wireless communication between a toll collection lane for guiding a vehicle to a toll station through a toll gate, and an ETC in-vehicle device mounted on the vehicle; A vehicle detector installed on the side of the toll collection lane and an open / close bar installed on the exit side of the toll collection lane are provided. When the vehicle detector detects the entry of the vehicle into the toll gate, the antenna device starts road-to-vehicle wireless communication with the ETC in-vehicle device and performs charging processing. When the charging process is completed normally, the open / close bar opens and the vehicle can pass through the toll booth. The toll collection lane is a lane (hereinafter referred to as ETC lane) for guiding a vehicle equipped with an ETC in-vehicle device to a toll station that performs charging processing via road-to-vehicle wireless communication and a vehicle not equipped with an ETC in-vehicle device. It can be roughly divided into lanes (hereinafter referred to as general lanes) for guiding to a toll booth where charging processing is performed through collection members. Japanese Patent Laid-Open No. 2009-4225 describes a navigation device for guiding and displaying a toll gate by distinguishing between an ETC lane and a general lane.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Here, the same reference numerals indicate the same components, and redundant description will be omitted.
FIG. 1 is a hardware configuration diagram of a navigation device 10 according to an embodiment of the present invention. The navigation device 10 is an on-vehicle device for guiding a recommended route from a departure point to a destination point to the vehicle 100. The navigation device 10 is a computer system including a position detection device 20, a storage device 30, a communication module 40, an operation unit 50, a navigation ECU (Electronic Control Unit) 60, and a guidance device 70.

  The position detection device 20 includes a GPS (Global Positioning System) that detects the absolute position of the vehicle 100, and a vehicle speed sensor and an orientation sensor that detect the relative position of the vehicle 100.

  The storage device 30 is a memory device such as an optical disc medium such as a CD-ROM or a DVD-ROM storing the map information 31 or a memory card. The map information 31 includes, for example, a road layer carrying information related to road connections of a plurality of different countries, a background layer carrying information for displaying a background object, and information for displaying characters such as municipalities. And an IIS layer that carries integrated information service (IIS) information. The road layer treats a road section from one intersection to another as a graph link by graph theory, and treats an intersection as a node of the graph. The road layer includes information relating to the connection relationship between nodes and links, and information indicating the type of link (for example, the distinction between a general road and a toll road). The map information 31 further includes attribute information 90 of the automatic toll collection system of each country as shown in FIG. Details of the attribute information 90 will be described later.

  The communication module 40 receives traffic information (for example, traffic jam information, accident information, construction information, traffic regulation information) from the road traffic information communication system.

  The operation unit 50 is a user interface such as a touch panel or a remote control that receives an operation input (for example, a setting input such as a destination point or a route search condition) from an occupant (a driver or a passenger).

  The navigation ECU 60 receives the position information of the vehicle 100 detected by the position detection device 20, the map information 31 read from the storage device 30, the traffic information received by the communication module 40, and the setting information input through the operation unit 50. The recommended route is searched based on (for example, setting information such as a destination point or a route search condition).

  The guiding device 70 is a user interface for guiding the recommended route searched by the navigation ECU 60 and an auxiliary route to be described later to a passenger (driver or passenger), and a display for visually guiding the recommended route or the auxiliary route through image display. A device 71 and a sound output device 72 that aurally guides the recommended route and the auxiliary route through the sound output are provided. The display device 71 is, for example, a liquid crystal display, and the sound output device 72 is, for example, a speaker.

  The navigation ECU 60 includes a processor 61 and a storage resource 62. The storage resource 62 is a storage area (logical device) provided by a computer readable recording medium (physical device). The computer readable recording medium is, for example, a storage device such as a semiconductor memory (volatile memory, non-volatile memory) or a disk medium. The storage resource 62 stores a navigation program 63 for realizing various navigation functions (for example, a setting function of a search base point, a search function of a recommended route, a search function of an auxiliary route, and a generation and guidance function of route information). The processor 61 reads the navigation program 63 stored in the storage resource 62, interprets and executes it.

  Here, the setting function of the search base point is a function of obtaining position coordinates (longitude and latitude) serving as a base point of the recommended route search such as a departure point, a target point, and a passing point. The recommended route search function is a function of setting a search range of the recommended route from a route search base point such as a departure point, a target point, and a passing point, and searching for a recommended route satisfying the search condition. The auxiliary route search function searches for a detour route that detours the recommended route based on traffic information (for example, information such as unpredictable traffic congestion or accident), or is recommended when the vehicle 100 deviates from the recommended route. It is a function of searching for a return route for returning to the route. The auxiliary route is a route that collectively refers to the detour route and the return route. The route information generation and guidance function is a function of generating and outputting an image signal and an audio signal for guiding various routes (recommended route and auxiliary route). In the search for the recommended route, for example, the Dijkstra method is used, and in the search for the auxiliary route, for example, a genetic algorithm is used.

  The ETC in-vehicle unit 80 performs road-to-vehicle wireless communication with the toll booth of the ETC system, and exchanges information required for billing processing (such as ETC card number, entrance toll booth, exit toll plaza, toll, etc.) It is an on-vehicle device that settles the charge. Performing charging processing through such road-to-vehicle wireless communication is called wireless charging. The ETC in-vehicle unit 80 is connected to the navigation device 10, and transmits charging information to the navigation device 10. The charging information transmitted to the navigation device 10 is transmitted to the passenger (driver or passenger) of the vehicle 100 through the guiding device 70 as needed.

  FIG. 2 shows attribute information 90 of the automatic toll collection system. The attribute information 90 associates identification information (ID) 91 of the automatic toll collection system, position information 92 of the automatic toll collection system, and information 93 indicating the presence or absence of the toll gate of the automatic toll collection system.

  FIG. 3 is a flowchart showing the process flow of the navigation method according to the embodiment of the present invention. The navigation program 63 describes a command for instructing the processor 61 to execute the process shown in FIG. The processor 61 interprets and executes the navigation program 63 to control each part (the position detection device 20, the guidance device 70, etc.) of the navigation device 10, and executes the processing shown in FIG.

  First, the processor 61 detects the position information of the vehicle 100 using the position detection device 20 (step 301).

  Next, the processor 61 detects the position information of the vehicle 100 detected by the position detection device 20, the position information 92 of the automatic toll collection system stored in the storage device 30, and the toll gate stored in the storage device 30. Based on the information 93 indicating the presence or absence of the vehicle, it is determined whether the toll gate of the automatic toll collection system expected to pass the vehicle 100 is present (step 302). By comparing the position information of the vehicle 100 with the position information 92 of the automatic toll collection system, it is possible to specify an automatic toll collection system that is expected to be passed by the vehicle 100. Further, with regard to the automatic toll collection system expected to pass vehicle 100, the presence or absence of the toll gate of the automatic toll collection system expected to pass by vehicle 100 can be obtained by referring to information 93 indicating the presence or absence of the toll gate. It can be determined.

  Next, the processor 61 determines whether the vehicle 100 is in a wireless charging enabled state with the automatic toll collection system (step 303). When an ETC card whose expiration date has not expired is inserted in the ETC in-vehicle device 80, it is determined that the vehicle 100 is in a wireless chargeable state with the automatic toll collection system. On the other hand, when the ETC card is not inserted into the ETC in-vehicle unit 80, or when the ETC card inserted in the ETC in-vehicle unit 80 has expired, the vehicle 100 communicates with the automatic toll collection system. It is determined that the wireless charging is not possible.

  The wireless charging is not limited to the method using the ETC card, and for example, the information recorded in the in-vehicle RFID is read through an RFID (Radio Frequency Identification) reader disposed on the roadside of the toll collection lane, Includes a method to charge processing. When the vehicle 100 uses a method for wireless charging using RFID instead of the method for wireless charging using an ETC card, in step 303, the processor 61 determines whether the RFID is mounted on the vehicle 100 or not. Determine if When the RFID is mounted on the vehicle 100, it is determined that the vehicle 100 is in a wireless chargeable state with the automatic toll collection system. On the other hand, when the RFID is not mounted on the vehicle 100, it is determined that the vehicle 100 is not in a wireless chargeable state with the automatic toll collection system.

  If the automatic toll collection system that is expected to pass the vehicle 100 has a toll gate, and the vehicle 100 is in a wireless chargeable state (step 304; YES), the display device 71 receives the toll. The guidance of the gate is displayed (step 305). At this time, for example, as shown in FIG. 4, the display device 71 distinguishes the ETC lane from the general lane and displays the guidance of the toll gate so as to guide the vehicle 100 to the toll bill capable of wireless charging. Well, you may also display a toll together.

  If the automatic toll collection system that is expected to pass the vehicle 100 has a toll gate, and the vehicle 100 is not in a wireless chargeable state (step 306; YES), the display device 71 receives a toll. The guidance of the gate is displayed (step 307). At this time, for example, as shown in FIG. 5, the display device 71 distinguishes the ETC lane from the general lane and displays the guidance of the toll gate so as to guide the vehicle 100 to the tollgate performing the charge processing through the collection member. You may

  If the automatic toll collection system that is expected to pass the vehicle 100 does not have a toll gate, and the vehicle 100 is in a wireless chargeable state (step 308; YES), the display device 71 receives the toll. The gate guidance is not displayed (step 309). At this time, for example, as shown in FIG. 6, the display device 71 may display the toll without displaying the guidance of the toll gate.

  If the automatic toll collection system that is expected to pass the vehicle 100 does not have a toll gate, and the vehicle 100 is not ready for wireless charging (step 310; YES), the display device 71 receives a toll. The guidance of the gate is not displayed (step 311). At this time, for example, as shown in FIG. 7, the display device 71 instructs the driver that the vehicle 100 passes through the toll booth without wireless charging without displaying the guidance of the toll gate. You may display cautions to inform you and tolls.

  The cooperation of the hardware resources of the navigation device 10 and the navigation program 63 realizes a function as means for executing the processing of steps 301 to 311. Functions similar to such functions may be implemented using dedicated hardware resources (eg, application specific integrated circuits (ASICs)) or firmware.

  As described above, according to the navigation device 10 related to the present embodiment, although the automatic toll collection system expected to pass the vehicle 100 does not have a toll gate, It is possible to eliminate the conventional inconvenience that the guidance is displayed.

    The embodiments described above are for the purpose of facilitating the understanding of the present invention, and are not for the purpose of limiting the present invention. The present invention can be changed or improved without departing from the gist thereof, and the present invention also includes the equivalents thereof.
