  2. Description of the Related Art Conventionally, for example, a navigation device such as a car navigation system that supports the travel of a vehicle such as an automobile by guidance based on map information is known. The map information used in the navigation device is generally map information created with a configuration suitable for guiding and driving the vehicle based on the standard map information. In addition, in navigation devices, for example, VICS (registered trademark) (Vehicle Information Communication System) developed and used in Japan is used, and traffic jams are generated by radio waves output from so-called beacon transmitters. There is also known a configuration that guides and guides using traffic information (so-called VICS data) such as information and traffic regulation information. Such traffic information is based on the position information constituting the standard map information, and the traffic information cannot be used as it is in the map information used in the navigation device. Therefore, a configuration is known in which standard map information and map information used in a navigation device are associated with each other (see, for example, Patent Document 1).

  The one described in Patent Document 1 is a standard map database based on a topographic map by the Japan Digital Road Map Association composed of nodes and links, and a dedicated map composed of nodes and rings based on a city planning map. It has a map database. Then, the comparison unit compares the standard map database with the dedicated map database, associates link groups, associates nodes included in the associated link groups, and creates and stores a link correspondence table. As a node association, a node within a certain distance of the dedicated map database from a node in the standard map database is regarded as a candidate for association, and a link group connected to that node is associated with another link group connected to the candidate node. Is determined, and it is determined whether or not the nodes are at the same position. And by providing the memory which memorize | stored the correlation table, the map database produced by the different method is matched mutually and the structure which can process easily the road traffic information based on any map database is taken.

  The server communication unit 210 executes a preset input interface process for a signal input via the network 101 and outputs the processed signal as a processing signal to the server calculation unit 250. In addition, when a processing signal to be transmitted to the transmission destination such as the guidance apparatus 300 is input from the server calculation unit 250, the server communication unit 210 outputs an output interface set in advance for the input processing signal. The process is executed and output as a server signal to a transmission destination such as a predetermined guidance and guidance device 300 via the network 101. The server signal can be output only to a predetermined transmission destination as appropriate based on information described in the processing signal.

It can be illustrated.

  The server storage unit 240 is controlled by the server calculation unit 250 and stores information related to the map so that the server calculation unit 250 can read the map. This server storage means 240 can be read out on various recording media such as a magnetic disk such as an HD (Hard Disk), an optical disk such as a CD (Compact Disc) and a DVD (Digital Versatile Disc), a magneto-optical disk, a memory card, and a semiconductor memory. A configuration including a drive and a driver stored in the memory, a configuration constructed by a plurality of drives and drivers, and the like can be applied. The server storage unit 240 includes a reference map database 241, a navigation map database 242, a traffic information processing database 243, and the like. The reference map database 241 is constructed in a table structure that stores reference map data distributed from the digital road map database 400.

  The navigation map database 242 is constructed in a table structure that stores navigation map data for guiding and guiding the travel of the vehicle using the map information by the guidance and guidance device 300. That is, the navigation map database 242 includes display data VM that is so-called POI (Point Of Interest) data as shown in FIG. 3, for example, matching data MM as shown in FIG. , Etc.

  The navigation map data display data VM includes, for example, a plurality of display mesh information VMx each having a unique number added thereto. That is, the display data VM is divided into a plurality of pieces of display mesh information VMx relating to a part of the region, and a plurality of pieces of display mesh information VMx are continuously arranged in the vertical and horizontal directions. Note that the display mesh information VMx may be further divided into a plurality of lower display mesh information VMx for a part of the area as appropriate. Each display mesh information VMx is divided into a rectangular shape with the length of one side set, that is, the actual topographical length shortened according to the scale of the map, and the map information is displayed at predetermined corners. It has information on absolute coordinates ZP on the whole, for example, the map of the earth.

  The display mesh information VMx includes, for example, name information VMxA such as an intersection name, road information VMxB, and background information VMxC. The name information VMxA is configured in a table structure of data in which other element data in the area, for example, the name of an intersection, the name of an area, and the like are arranged and displayed at a predetermined position in a positional relationship with the absolute coordinate ZP. The road information VMxB is configured in a data table structure in which a road, which is road element data in the region, is arranged and displayed at a predetermined position in a positional relationship with the absolute coordinate ZP. In the background information VMxC, a mark indicating a famous place or building that is other element data, or image information that is other element data indicating the famous place or building, etc. is determined in a positional relationship with the absolute coordinate ZP. It is structured in a table structure of data arranged and displayed at positions.

  On the other hand, like the display data VM, the matching data MM is divided into a plurality of pieces of matching mesh information MMx related to, for example, a partial region to which a unique number is added, and a plurality of pieces of matching mesh information MMx are continuously formed vertically and horizontally. Has been. Note that the matching mesh information MMx may be further divided into a plurality of lower-layer matching mesh information MMx regarding a part of the region as appropriate. Each matching mesh information MMx is divided into a rectangular shape with the length of one side set, that is, the length on the actual terrain shortened according to the scale of the map, and the entire map information is divided into predetermined corners. For example, it has information on absolute coordinates ZP on a map of the earth. Note that the matching mesh information MMx may have a different data structure representing an area different from the display mesh information VMx, that is, the scale of the divided area may be different. Here, if the scales are the same, data may be associated using information of a unique number, and if the scales are different, for example, the data may be associated using absolute coordinates ZP. The matching data MM represents the vehicle in order to prevent erroneous display such as when the display representing the vehicle is located on the building instead of on the road when the moving state of the vehicle is superimposed on the map information. This is used for map matching processing for correcting the display so that the display is positioned on the road. This matching data MM has a plurality of link string block information.

  As shown in FIG. 4, in the link string block information, a plurality of links L as line segment information that is a line segment connecting the nodes N as the point information constituting the road and representing the points are associated with a predetermined regularity. It is a table structure of data. More specifically, the links L are associated with each other as a continuous link row that is continuous on a broken line, such as a continuous road such as a Koshu highway or an Ome highway. The link L is line information unique to each link L (hereinafter referred to as a link ID) and node information such as a unique number representing two nodes N connected by the link L. And have. The node N corresponds to a nodal point such as an intersection, a turning point, a branching point, or a merging point of each road. The information about the node N includes a node ID (identification) as point specific information that is a unique number added to each node N in the link string block information, coordinate information of a position where each node N exists, and an intersection. And flag information which is branch information indicating whether or not a branch position where a plurality of links such as branch points intersect. Note that the node N has only point-specific information and coordinate information that does not have flag information in order to simply represent the shape of the road, and attribute information that is information representing the configuration of the road such as a tunnel or the width of the road. Some have further added. The node N that simply does not have the flag information and simply represents the shape of the road is not used for the traffic information processing described later.

  Further, the travel route search map information has, for example, the same table structure as the matching data MM, that is, point information representing points such as a node N representing roads and line segment information connecting points such as links L. The table structure is an information structure for representing a road in order to search for a movement route.

  Then, as shown in FIG. 5, the traffic information processing database 243 includes traffic information processing data 243A as processing data for associating the VICS data corresponding to the node of the reference map data with the navigation map data. It is constructed in a table structure for storing a plurality. That is, the traffic information data 243A includes a node ID 243A1 that is point information of reference map data corresponding to a node ID that is position information of VICS data, and a node of navigation map data that corresponds to the same point as the point of this node ID. Node ID 243A2 which is N point information and reference map data version information 243A3 corresponding to the node ID of VICS data are associated with one data structure.

  The server storage unit 240 stores, for example, search information for acquiring information on a predetermined point in the navigation map data. In other words, the search information includes various information such as the prefecture name, municipality name, district name, point name, etc., guidance, and various information related to the store as a point, which are areas that are sequentially subdivided on the map information. For example, the table structure has a tree structure in which item information is associated in a hierarchical manner. Further, the server storage unit 240 also stores various programs developed on an OS (Operating System) that controls the operation of the entire server device 200. In addition, the server storage unit 240 can temporarily store signals processed by the server calculation unit 250 during calculation, that is, also functions as a memory.

  The server calculation means 250 includes, for example, a CPU (Central Processing Unit), and is an input / output port to which the server communication means 210 is connected, an input port to which the server operation means 220 is connected, and a server display, which are various input / output ports (not shown). A display control port to which the means 230 is connected, a storage port to which the server storage means 240 is connected, and the like. The server calculation unit 250 includes a reference map data acquisition unit 251, a node extraction unit 252, an identical node setting unit 253, a processing data generation unit 254, and the like as various programs.

  The reference map data acquisition unit 251 controls the server communication unit 210 to acquire reference map data distributed from the digital road map database 400 via the network 101. At the time of this acquisition, the version information of the reference map data is also acquired. Then, the reference map data acquisition unit 251 appropriately outputs the acquired reference map data to the reference map database 241 of the server storage unit 240 and stores it.

  The node extraction unit 252 extracts the node N from the reference map data and the navigation map data. In this extraction process, if the reference map data and the navigation map data are in different formats, the nodes are extracted after conversion into the same format. As the extraction of this node, for example, a node on a condition that three or more links are connected, that is, a node corresponding to an intersection is extracted from the reference map data. Each node is extracted as a node ID and stored in the server storage unit 240 as appropriate.

  The same node setting means 253 has the same position when the node ID of the node of the reference map data determined as the same position and the node ID of the node N of the navigation map data are determined to be the same. Set to associate as. As the same determination of this position, for example, as shown in FIG. 6, the nodes and links of the reference map data and the navigation map data are compared so that the screen display of the nodes and links displayed in the form of a road network is superimposed. Thus, the overlapping nodes are determined to be at the same position. Further, even if the nodes do not overlap, if they are nodes indicating the same intersection, such as incidental information included in the node information, for example, an intersection, it is determined whether or not they are at the same position. Further, for nodes that do not overlap, it is determined whether or not they are at the same position based not only on the incidental information but also on the node information and the connection state of the link connected to the node.

  That is, as in “1 to 1” in the comparison condition shown in FIG. 7, the incidental information or connection is made with nodes that are in an overlapping state or approximate values that do not overlap but the coordinates included in the node information are within a predetermined range. When it is determined that they are the same based on the connection state of the link, etc., they are set as the same node. That is, the node ID 243A1 in the node of the corresponding reference map data is associated with the node ID in the node N of the navigation map data. In FIG. 7, for convenience of explanation, “A” is attached as the node ID 243A1 near the node, and “A” is attached near the node N for the purpose of associating “A” with the node ID 243A2 of the navigation map data. A corresponding relationship is indicated by an arrow.

  In addition, as shown in “1 to many” in the comparison condition shown in FIG. 7, the reference map data is used for navigation that supports driving of the vehicle even if it is represented by a single node as an intersection to indicate a road. In the navigation map data, the intersection may be indicated by four nodes in order to indicate the traveling direction of the vehicle. Even in such a case where they do not overlap, if they are determined to be the same based on the incidental information or the connection state of the link to be connected, they are set as the same node. In FIG. 7, for convenience of explanation, “A” is attached adjacent to each node N of the navigation map data corresponding to the node of the reference map data, and the corresponding relationship is indicated by an arrow.

  Furthermore, since the navigation map data is used for navigation that supports the driving of vehicles, road maps that are not appropriate for guidance and guidance, such as extremely narrow roads where vehicles cannot enter or pedestrian-only roads, appear as intersections. There may not be. Specifically, as in the “many-to-one” comparison condition shown in FIG. 7, even if the intersection is constituted by a plurality of nodes in the reference map data, it is represented as one node in the navigation map data. As in “1 to 0” in the comparison condition shown in FIG. 7, even if the node is an intersection in the reference map data, it is not represented as an intersection in the navigation map data and there is no corresponding node. Even if they do not overlap, if they are determined to be the same based on the incidental information or the connection state of the link to be connected, they are set as the same node. That is, the same node is set for the reference map data and the navigation map data under the four contrast conditions shown in FIG. For convenience of explanation, “many-to-one” in FIG. 7 is adjacent to one node N of the navigation map data corresponding to the four nodes of the reference map data, and “A”, “B” of each node ID 243A1. ”,“ C ”, and“ D ”, and the corresponding relationship is indicated by arrows.

  The setting associated with the same node in the same node setting unit 253 is performed by recognizing that the reference map data is distributed from the digital road map database 400 and acquired by the server communication unit 210, for example. For example, it may be performed based on a setting input by the server operation unit 220. As a setting method, as shown in FIG. 6, the overlapping state of the reference map data and the navigation map data in the form displayed on the screen is determined by image processing, or each item constituting the node information and connection to the node are connected. It is possible to score the identity of each item constituting the link information to be judged and determine the identity based on the score value, or to apply various automatic calculation processes. Moreover, the operator in the server operation unit 220 may manually perform setting input for associating the same node. When the same node setting unit 253 recognizes that the setting of the association with the navigation map data is completed for all the nodes of the reference map data, the same node setting unit 253 outputs the fact to the processing data generation unit 254.

[Operation of guidance guidance system]
Next, as the operation of the guidance and guidance system, a driving support process for guiding and guiding the movement of the vehicle based on the set movement route will be described with reference to the drawings. FIG. 9 is a flowchart showing the operation of the driving support process of the reproduction system. FIG. 10 is a flowchart showing the operation of the guidance guidance process in the driving support process.

  When a passenger who is a user on the vehicle turns on the power of the guidance and guidance device 300 and supplies power, the terminal computing unit 370 performs initial setting and controls the terminal display unit 340 by the notification control unit 375. To display the main menu. That is, the terminal display unit 340 displays a display screen that prompts the user to input settings for the content to be operated by the guidance and guidance device 300. For example, at the time of initial setting, the guidance and guidance device 300 performs processing for acquiring the traffic information processing data 243 </ b> A updated by the server device 200 by the terminal calculation unit 370. For example, the terminal communication unit 320 receives the version information 243A3 of the traffic information processing data 243A stored in the traffic information processing database 243 of the server device 200, and compares the version information 243A3 with the traffic information processing data 243A of the terminal storage unit 360. When the information processing data 243A is stored in the server device 200, the new traffic information processing data 243A is received and stored in the terminal storage unit 360. Note that the acquisition method of the latest traffic information processing data 243A is not limited to this method.

  Then, as shown in FIG. 9, when the terminal calculation unit 370 recognizes an operation signal corresponding to an input operation requesting the setting of the movement route from the main menu (step S101), the notification control unit 375 causes the movement route to be determined. The terminal display unit 340 displays a display screen for prompting input of various information necessary for the search, for example, setting item information such as destination, shortest distance or shortest time. Further, when recognizing various kinds of information necessary for the search for the movement route based on the input operation of the terminal operation unit 330, the terminal calculation unit 370 first performs a process of recognizing the current position by the current position recognition unit 371 (step S102). ), Processing for recognizing the destination set and inputted by the destination recognition means 372 (step S103). Further, the terminal calculation unit 370 causes the notification control unit 375 to control the terminal display unit 340 to display a display prompting input operation of various setting items that are conditions such as the shortest time and the shortest distance for searching for a moving route. . Then, when the user sets and inputs the setting items by the input operation of the terminal operation unit 330 in accordance with the instruction on the displayed display screen, the terminal calculation unit 370 sets the setting item information regarding the set items that have been set and the terminal communication unit. The VICS data acquired at 320 is acquired (step S104). The acquired current position information, destination information, setting item information, and VICS data are appropriately output to the terminal storage unit 360 and stored.

  Thereafter, the terminal calculation means 370 causes the route processing means 376 to go from the current position of the vehicle to the destination based on the current position information, destination information, setting item information and VICS data stored in the terminal storage means 360. The route search process for searching for the travel route is performed using the navigation map data stored in the terminal storage unit 360 (step S105). Then, the route processing unit 376 detects a plurality of, for example, five travel routes that match the set item information, calculates the required time to the destination on each travel route, and generates the required time information. When the notification control unit 375 recognizes that the route processing unit 376 has detected the travel route and generated the required time information, the notification control unit 375 displays the travel route information and the required time information regarding the travel route on the terminal display unit 340 and also by the user. Display a request for selection. Thereafter, the movement route is set by an input operation in which the user selects any one of the movement route information.

  With this travel route setting, the notification control unit 375 of the terminal computing unit 370 reads out the navigation map data of a predetermined scale from the terminal storage unit 360 and superimposes the set travel route and current position icons on the map information. And displayed on the terminal display means 340. In addition, when the input setting of superimposing and displaying predetermined traffic information or feature information is made in advance, it is superimposed on the navigation map data based on the information and appropriately displayed.

  And the terminal calculating means 370 performs a guidance guidance process based on the present position of the vehicle (step S106). In this guidance and guidance process, for example, as shown in FIG. 10, the VICS data acquisition standby state is set (step S201). That is, the terminal calculation unit 370 determines whether or not the VICS data has been received by the terminal communication unit 320. Then, when the processing means 373 receives the VICS data, the terminal computing means 370 performs processing associated with the navigation map data, that is, associated with the data structure that can be used in the navigation map data, based on the traffic information data 243A received in advance ( Step S202).

  Specifically, the processing means 373 performs processing for associating the node ID of the navigation map data with the node ID that is information corresponding to the node ID of the reference map data regarding the position of the VICS data, that is, the same position as the VICS data. Is associated as one data structure. Then, the terminal calculation means 370 causes the notification control means 375 to display the display or voice corresponding to traffic conditions such as traffic jams or traffic restrictions on the navigation map information superimposed on the navigation map information based on the VICS data. The passenger is notified of the traffic situation by displaying the sound or outputting the sound with the terminal sound generation means 350.

  Further, the terminal calculation unit 370 determines whether or not the route processing unit 376 needs to perform a reroute process that is a re-search of the movement route based on the acquired VICS data (step S203). For example, it may be determined whether or not a traffic jam occurs on the travel route that has already been set and the travel time required for the travel route is long.

  In step S203, if it is determined that reroute processing is necessary, for example, it is determined that traffic congestion or traffic regulation has occurred, traffic congestion or traffic regulation has been canceled, etc., the travel route is searched again in the same manner as in step S105 (step S105). S204). As a result of the reroute process in step S204, when a new travel route candidate is searched, the notification control unit 375 displays the screen on the terminal display unit 340 to notify the passenger, and whether to change the terminal operation unit 330 or not. A display screen prompting the user to input such settings is displayed on the screen. In addition, as a new travel route candidate, for example, a new travel route that avoids traffic jams or a travel route that is set for avoiding traffic jams and traffic restrictions is a travel route due to cancellation of traffic jams and traffic regulations. A moving route candidate such as a new moving route that shortens the time can be exemplified. When the terminal computing unit 370 recognizes a setting input for changing to the notified new moving route candidate, the terminal calculating unit 370 sets a newly searched and selected moving route, that is, stored in the terminal storage unit 360. Rewrite the previous travel route and store it. When the terminal calculation means 370 recognizes a setting input indicating that no change is made, the previously set movement route is maintained as it is, that is, the stored state is maintained.

  After the reroute process in step S204, the terminal calculation unit 370 (step S205) guides and guides the vehicle travel based on the travel route stored in the terminal storage unit 360. That is, the terminal calculation means 370 recognizes the movement state of the vehicle based on the detection signals output from the speed sensor, the azimuth angle sensor, and the acceleration sensor of the sensor unit 310 and the GPS data output from the GPS receiver unit. . Further, the terminal calculation means 370 generates guidance information related to vehicle movement by the guidance information generation means 374 based on the recognized movement situation and movement route, and displays the screen on the terminal display means 340 by the notification control means 375. The terminal sounding means 350 outputs a voice or makes a notification to guide the vehicle movement.

  On the other hand, if it is determined that the re-search in step S203 is not necessary, for example, if it is determined that there is no difference from the traffic situation of the VICS data acquired previously, the process proceeds to step S205, and the vehicle is based on the previously set travel route. Guide the movement of In the guidance and guidance in step S205, it is determined whether or not the current position has reached the destination every time the vehicle moves and the movement situation fluctuates based on the detection signal from the sensor unit 310 (step S206). If it is determined in step S206 that the destination has not yet been reached, the process returns to step S201 to continue the guidance guidance process. On the other hand, if it is determined in step S206 that the vehicle has arrived at the destination, the guidance guidance process ends, and the driving support process ends.

[Effects of guidance guidance system]

Can be easily obtained, and the traffic information processing database 243 can be centrally managed, and appropriate guidance can be provided.

  Further, the traffic information database 243 is constructed by the server device 200 that receives the reference map data distributed from the digital road map database 400, and is distributed to the guidance and guidance device 300. For this reason, since the traffic information processing database 243 for making the VICS data available in correspondence with the navigation map data is constructed by the server device 200 that acquires the reference map data to be compared with the navigation map data, fluctuations in road conditions Even if the reference map data is updated correspondingly, the traffic information processing database 243 can be easily updated, and appropriate guidance can be provided. In particular, since the traffic information processing data 243A includes the reference map data version information 243A3, the update status of the reference map data can be easily determined, and the traffic information processing database 243 can be easily managed.

  And as traffic information processing data 243A, it is set as the structure which linked | related node ID of the reference map data showing the same point, and ID data of navigation map data. Therefore, the VICS data can be easily used in correspondence with the navigation map data with an extremely simple table structure, and the traffic information processing database is installed even in the guidance and guidance device 300 that is mounted on a vehicle and has many structural restrictions. 243 can be constructed. Furthermore, as the association of the nodes at the same position, the traffic information processing data 243A is generated in association with the node ID. For this reason, the table structure of the traffic information processing data 243A can be simplified, that is, the data amount can be small, the configuration of the server storage unit 240 and the terminal storage unit 360 can be simplified, the capacity can be effectively used, and the traffic information processing database 243 Easy construction is obtained.

For this reason, the generation process of traffic information processing data 243A is easy and can be generated in a short time.

  Further, as a node extracted from the reference map data and the navigation map data, a node having a condition that three or more links are connected, that is, a node corresponding to an intersection serving as a reference of guidance information for guidance guidance is extracted. For this reason, traffic information processing data 243A necessary and sufficient for associating the VICS data for guiding and guiding the movement of the vehicle with the navigation map data can be generated, and the traffic information processing database 243 can be easily constructed in a short time.

  Further, as traffic information processing data 243A, for example, as shown in FIG. 6, the screen display displayed in the form of a road network of nodes and links is overlapped so that the nodes of the reference map data and the nodes of the navigation map data The position identity is determined, and nodes at the same position are constructed in association with one data structure. Therefore, it is easy to determine the identity of the position of the node of the reference map data and the node of the navigation map data, the traffic information processing data 243A can be easily generated, the calculation processing load for generation is reduced, and the It can be generated in a short time with a simple configuration. Then, when comparing the reference map data and the navigation map data, for example, when the screen display is overlaid as shown in FIG. 6 described above, the data forms that can be compared, that is, the data that can be displayed on the screen, respectively. Change to structure. As a result, the traffic information processing data 243A can be easily generated.
