Reference numeral 18 is an application program that operates under the control of the microcomputer.

  Based on the map data obtained from the map information acquisition unit 5, the vehicle position detection unit 2 determines the vehicle position from the current position data from GPS (Global Positioning System), the speed data from the vehicle speed sensor, and the direction data from the gyro sensor. Is detected. The operation input unit 3 receives a switch operation, a touch panel operation, an input operation by a remote controller or the like from a user. The external information acquisition unit 4 receives the information via a receiver or a mobile phone via an antenna, and acquires external data such as traffic information such as traffic jams and traffic closures, weather along the route, and road surface conditions. The map information acquisition unit 5 reads map data from a storage device such as an HDD (Hard Disk Drive), a DVD (Digital Versatile Disc), or a large-capacity memory card.

  The map matching unit 11 associates the current position detected by the host vehicle position detection unit 2 with the map represented by the map data read from the map information acquisition unit 5, and specifies the current position of the moving body. The host vehicle position detection unit 2 and the map matching unit 11 constitute a host vehicle position specifying unit 9.

  The multiple route search unit 12 includes operation data from the operation input unit 3, map data from the map information acquisition unit 5, vehicle position data from the vehicle position specifying unit 9, and external data from the external information acquisition unit 4. Based on the above, a plurality of routes from the point (departure point or the like) input by the operation input unit 3 or the current position to the destination input by the operation input unit 3 are searched. The guidance route determination unit 13 determines a route to be guided based on the operation data from the operation input unit 3 and the plurality of route data from the multiple route search unit 12. The route guidance unit 14 uses the speaker 6 and the display unit 7 to guide the route determined by the guidance route determination unit 13 based on the map data from the map information acquisition unit 5 and the vehicle position data from the vehicle position specifying unit 9. Do through.

  The all route display generation unit 16 is based on the map data from the map information acquisition unit 5, the vehicle position data from the vehicle position specifying unit 9, and the plurality of route data from the multiple route search unit 12. A map on which all routes from to the destination are posted is created and displayed on the display unit 7 such as a monitor. The multiple route display generation unit 17 is based on the map data from the map information acquisition unit 5, the own vehicle position data from the own vehicle position specifying unit 9, and the multiple route data from the multiple route search unit 12. A map on which the route is posted is created and displayed on the display unit 7 such as a monitor. In general, a map including the vehicle position is generated, but the vehicle position may not be included depending on the case of scrolling or displaying a destination or a facility on the way.

  The information calculation acquisition unit 15 includes map data from the map information acquisition unit 5, vehicle position data from the vehicle position specifying unit 9, external data from the external information acquisition unit 4, and a plurality of data from the multiple route search unit 12. Based on the route data, the number of facilities such as gas stations, convenience stores, restaurants, and toilets along each route from the current position to the destination in multiple routes, how many signals, crossings, etc. Calculate the distance to the destination, estimated arrival time, and fees. The information display generation unit 18 generates route information to be displayed on the display unit 7 based on the data from the information calculation acquisition unit 15. The output unit 8 includes a speaker 6 and a display unit 7. The output unit 8 outputs route guidance information from the route guide unit 14 to the speaker 6 and the display unit 7, or from the entire route display generation unit 16 including the vehicle position. All routes, a plurality of routes from the multiple route display generation unit 17, and route information from the information display generation unit 18 are displayed on the monitor of the display unit 7.

  The operation of the navigation device configured as described above will be described with reference to the flowchart of FIG. 4 and 5 are display examples of the screen of the navigation device. First, in step S100, it is determined whether a destination is set by an input from the operation input unit 3. If not set, the process waits until the destination is set. If set, the process proceeds to step S110.

  In step S110, the multiple route search unit 12 searches for a predetermined number, for example, five multiple routes. Search conditions include, for example, toll (the route that uses the toll road to achieve the shortest time), general (the route that does not use the toll road as much as possible), distance (the route that has the shortest distance), and cost savings (toll road fee and fuel (Recommended route with lower price), recommended (recommended route with a balance of time, distance, fee, etc.). In step S120, the process waits until the search for a predetermined number of routes is completed. When the search is completed, the process proceeds to step S130.

  Each searched route is created by the multiple route display generation unit 17 by changing the color and shape, and the plurality of routes are always displayed on the display unit 7. FIG. 4 shows a screen display example at that time. In this figure, the black triangle below the center of the map indicates the vehicle mark and indicates the current position of the vehicle. Black circles, white circles, squares, triangles, and star shapes respectively indicate routes searched mainly for recommended, paid, general, distance, and cost savings. Each route to the destination and the required time are displayed. Each route may be a solid line, a dotted line, a broken line, or the like, or the thickness, color, shape, transmittance, etc. may be changed, or these may be combined. Also, the user may select whether or not to display for each route, or the user may determine the number of routes to be displayed and select which route to display.

  In step S130, the guide route determination unit 13 waits for the user to select a guide route. If selected, the process proceeds to step S140. In step S140, the route guidance unit 14 starts guidance on the route selected by the user among the plurality of routes. In FIG. 4, it is shown that the “recommended” route surrounded by the thick line frame in the right column is selected, and the thick lines extending above and below the center of the map represented by the black circle marks are shown. This is the selected route, and the recommended route is guided.

  In step S150, it is determined whether the destination has been reached. When it arrives, it progresses to step S160 and complete | finishes guidance. If not, the process proceeds to step S170.

  In step S170, it is determined whether the user has changed the guidance route. For example, the route can be changed by touching the “recommended”, “paid”, “general”, “distance”, and “fee saving” switches on the right side of the display in FIG. Operate or select a route. If changed, the process proceeds to step S140 to start guidance for the newly selected route. When not changing, it progresses to step S180, and here, it is judged whether the vehicle deviated from which route among five routes. If not deviating, guidance of the selected route is continued, and the process proceeds to step S150 and repeated in the same manner.

  If any route is deviated in step S180, the process proceeds to step S190. Here, it is determined whether the deviated route is a guide route. If the deviated route is not a guide route, the process proceeds to step S200, where the multiple route search unit 12 re-searches for another new route that replaces the deviated route, and the multiple route display generation unit 17 draws a plurality of routes. A map is created and displayed on the display unit 7. Since the guidance route has not been changed, the guidance of the selected route is continued, and the process proceeds to step S150 and is repeated in the same manner.

When the route deviates from the guide route in step S190, the multi-route search unit 12 re-searches for a new route that replaces the route deviated in step S210, and the multi-route display generation unit 17 creates a map with a plurality of routes drawn. Created and displayed on the display unit 7. If there are a plurality of deviated routes, the process waits until the route search is completed in step S220. When the search is completed, the process proceeds to step S230. Here, after the user selects a guidance route, guidance for the route is started. Then, it progresses to step S150 and it repeats similarly.

  In the navigation device configured as described above, since a plurality of routes are always displayed, the route can be arbitrarily changed by a user operation. At that time, if you display the distance from the current position for each route to the destination, the estimated arrival time, the charge, etc., using the display method (subwindow, balloon, etc.) associated with the switch in the screen good. The information calculation acquisition unit 15 acquires the information from the map information acquisition unit 5 and the external information acquisition unit 4, and the information display generation unit 18 generates route information and displays it on the monitor of the display unit 7 in real time. The user can arbitrarily select which route to use with reference to the information. Here, what should be displayed should be determined by user settings. In addition to distance, estimated arrival time, and charges, the number of information to be displayed includes the number of facilities such as gas stations, convenience stores, restaurants, and toilets along the route, route signals, railroad crossings, weather, road surface conditions, traffic regulations, congestion information, etc. You may use the condition of the route.

  Two switches are prepared for each route condition, and one displays the entire route map of the condition or a schematic diagram that reduces the amount of information such as narrow streets, facility marks, icons, etc. from this route map. The other one may be used for switching guidance to the route. For example, when the “all routes” switch next to the selection switch for each route in FIG. 4 is pressed, an all route map for that route is created by the all route display generation unit 16 and displayed on the monitor of the display unit 7. The When the “all routes” switch of a plurality of routes is pressed, all routes corresponding to the pressed routes are displayed.

  Alternatively, as shown in FIG. 5, one “all route” switch for displaying the entire route map of all conditions may be provided, and only the switch for switching to the route may be displayed for each condition. Further, the entire route map may be always displayed as a sub-window, screen division, or PinP (Picture in Picture), and a switch for switching to the route may be displayed.

  The arrangement of the switches may be fixed, or may be arranged in the order of conditions selected by the user. For example, when the user selects “time”, the switches are arranged in ascending order of required time as shown in FIG. In this case, the switch arrangement may be changed during the traveling.

  In the navigation device configured as described above, since a plurality of routes are always displayed on the map, it is possible to easily compare routes and change routes, and to obtain a navigation device with excellent convenience. At that time, information on each route is also displayed in real time, so that the user can easily compare the routes. Therefore, it becomes easy to change the route from the middle, and the convenience for the user is improved.
