The matching process corresponding to is executed. By this matching process, the vehicle position mark is formed on the map. Data representing the vehicle position mark obtained by the matching process is sent to the guidance guide unit 140.

  Next, the current location screen is displayed (step ST12). That is, the map display unit 110 reads the map data around the point indicated by the current position data sent from the vehicle position detection unit 90 from the map data storage unit 12, and based on the read map data, the monitor 2 Drawing data for displaying a map on the screen is generated and sent to the output unit 18. Further, the guidance guide unit 140 generates drawing data for displaying the vehicle position mark on the screen of the monitor 2 based on the data representing the vehicle position mark sent from the map matching unit 120, and outputs the drawing data. Send to 18. The output unit 18 generates a video signal based on the drawing data received from the map display unit 110 and the guidance guide unit 140 and sends it to the monitor 2. Based on the video signal sent from the output unit 18, the monitor 2 displays a map in which the vehicle position mark is superimposed on a map centered on the current position of the vehicle as a current location screen.

  Next, the destination is set (step ST13). That is, when the user performs an operation for instructing destination setting using the remote controller 3, a destination setting screen as shown in FIG. 4 is displayed on the monitor 2. In this destination setting screen, a portion surrounded by a rectangle is a button, and the user can execute a function assigned to the button by pressing the desired button using the remote controller 3. it can. The same applies to each screen described below.

  The user uses the remote controller 3 to select an address search, a facility search, a telephone number search, or the like, thereby setting a destination and a waypoint on the map displayed on the monitor 2. In this case, the user can set a plurality of waypoints. Data indicating the destination and waypoint set by the remote controller 3 is sent to the route search unit 130 via the input unit 17 and the HMI unit 100 of the navigation unit 1.

  Next, search conditions are set (step ST14). That is, when the destination setting in step ST13 is completed, a search condition setting screen as shown in FIG. The user sets the route search conditions displayed on the monitor 2 using the remote controller 3. Specifically, the user sets a search priority condition by pressing any one of the “fastest route”, “shortest route”, and “easy route” buttons representing route priority conditions. In addition, for each item of the expressway, toll road, ferry ship, avoidance route area, and time limit road, one of the “use” button and the “do not use” button is pressed to set whether to use them.

  The “map” button in the search condition setting screen shown in FIG. 5 is used to return the screen of the monitor 2 to the current location screen, the “decision” button is used to confirm the setting contents, and the “initial setting” button Is used to return the search condition to the initial value, and the “return” button is used to return to the previous screen. When the “OK” button on this search condition setting screen is pressed, data representing the set search conditions is sent to the route search unit 130 via the input unit 17 and the HMI unit 100 of the navigation unit 1.

  Next, route search processing is executed (step ST15). That is, the route search unit 130 determines a route from the current position indicated by the current position data received from the vehicle position detection unit 90 to the destination through the waypoint set in step ST13 in step ST14. Search according to the set search conditions. The route data representing the searched route is sent to the guidance guide unit 140.

  Next, route guidance processing is executed (step ST16). That is, the guidance and guidance unit 140 includes the current position data sent from the vehicle position detection unit 90, the data representing the vehicle position mark sent from the map matching unit 120, and the route sent from the route search unit 130. Based on the data, drawing data for displaying the guidance information map on the screen of the monitor 2 and voice data for outputting the guidance message by voice are generated and sent to the output unit 18.

  Next, route display is performed (step ST17). That is, the output unit 18 generates a video signal based on the drawing data representing the map sent from the map display unit 110 of the control unit 10 and the drawing data representing the route and the vehicle position sent from the guidance guide unit 140. To do. The video signal generated by the output unit 18 is sent to the monitor 2. As a result, the guidance route and route guidance are displayed on the monitor 2. In this state, after confirming that the route displayed on the monitor 2 is the intended route, the user starts guidance by pressing a button (not shown) provided on the screen of the monitor 2 or by voice. Instruct.

  Next, route guidance is started (step ST18). That is, when guidance start is instructed in step ST17, route guidance is started. Specifically, the output unit 18 displays video based on drawing data representing a map sent from the map display unit 110 of the control unit 10 and drawing data representing a route and the vehicle position sent from the guidance guide unit 140. While producing | generating a signal, an audio | voice signal is produced | generated based on the audio | voice data sent from the guidance guide part 140 of the control part 10. FIG. The video signal generated by the output unit 18 is sent to the monitor 2. As a result, the guidance route and route guidance are displayed on the monitor 2. The audio signal generated by the output unit 18 is sent to the audio speaker 4. As a result, a guidance message is output from the audio speaker 4. Thereafter, the guidance guidance messages corresponding to the environment that changes with the progress of the vehicle are sequentially output, so that the user drives the vehicle along the guidance guidance.

  Next, the route guidance process after the route guidance is started by the main process described above will be described with reference to the flowchart shown in FIG.

  When the route guidance is started, the user travels on the route according to the guidance. The navigation device executes a route guidance process (step ST21). This route guidance process is the same as the process when starting the route guidance in step ST18 described above.

  Next, it is checked whether or not the route toward the waypoint has deviated by Xm or more (step ST22). That is, the guidance and guidance unit 140 separates the route indicated by the route data sent from the route search unit 130 and the position indicated by the data representing the vehicle position mark sent from the map matching unit 120 by Xm or more. Find out if it was. Here, X can be an arbitrary value.

  If it is determined in step ST22 that the route has not deviated by more than Xm, the sequence returns to step ST21 and the guidance guidance process is continued. On the other hand, if it is determined in step ST22 that the route has deviated by Xm or more, then a waypoint selection message is output (step ST23). That is, the guidance guide unit 140 generates drawing data representing the waypoint selection message and sends it to the output unit 18, and also generates voice data and sends it to the output unit 18. As a result, the transit point selection message including the “Yes” button and “No” button as shown in FIG. 7 is displayed on the monitor 2 and “The route has been removed. Is output from the audio speaker 4. The transit point selection message corresponds to the “message” of the present invention.

  Next, it is checked whether or not the “Yes” button has been pressed (step ST24). That is, the guidance guide unit 140 checks whether data indicating that the “Yes” button has been pressed is sent from the remote control 3 via the remote control light receiving unit 21, the input unit 17, and the HMI unit 100.

  In step ST24, when it is determined that the “Yes” button has been pressed, it is recognized that the user has selected to pass the nearest waypoint, that is, the waypoint that is heading, and The route including it is searched again (step ST25). That is, the route search unit 130 has already set a route from the current position indicated by the current position data sent from the vehicle position detection unit 90 to the destination through the nearest waypoint. Search again according to the search conditions. The route data representing the re-searched route is sent to the guidance guide unit 140. Thereafter, the sequence returns to step ST21, and the route guidance process is continued.

  On the other hand, if it is determined in step ST24 that the “Yes” button has not been pressed, then it is checked whether the “No” button has been pressed (step ST26). That is, the guidance guide unit 140 checks whether data indicating that the “No” button has been pressed is sent from the remote control 3 via the remote control light receiving unit 21, the input unit 17, and the HMI unit 100.

  If it is determined in this step ST26 that the “No” button has been pressed, it is recognized that the user has selected not to pass through the nearest waypoint, that is, the waypoint that is heading, and the route point is automatically selected. Changes are made (step ST27). That is, the route search unit 130 collates the current position indicated by the current position data sent from the vehicle position detection unit 90 with the map indicated by the map data acquired from the map data storage unit 12, and the latest route Other waypoints existing beyond the ground are set as new waypoints.

  Next, a route including a waypoint existing before the nearest waypoint is searched again (step ST28). That is, the route searching unit 130 has already set the route from the new waypoint set in step ST27 to the destination, the state of the vehicle such as the position and traveling direction of the vehicle, and the like. Search again according to the search conditions. The route data representing the re-searched route is sent to the guidance guide unit 140. Thereafter, the sequence returns to step ST21, and the route guidance process is continued.

  In addition, it can comprise so that the process of step ST29 and step ST30 may be performed instead of the process of step ST27 and step ST28 mentioned above. Processing in this case will be described below. If it is determined in step ST24 that the “No” button has been pressed, it is recognized that the user has selected not to go through the nearest waypoint, that is, the waypoint that is heading, and the waypoint list is changed. Is performed (step ST27). That is, the route search unit 130 sends data representing all waypoints set at that time to the guidance guide unit 140. The guidance guide unit 140 generates drawing data for displaying a route list that is a list of route points based on the received data representing the route points, and sends the drawing data to the output unit 18. As a result, the waypoint list is displayed on the monitor 2. In this state, the user uses the remote control 3 to select a waypoint that is desired to be routed or to delete a place that is not desired to be routed. Thereby, a new waypoint is set.

  Next, the route including the changed waypoint is searched again (step ST30). That is, route search section 130 searches again for a route from the new waypoint set in step ST29 to the destination according to the already set search conditions. The route data representing the re-searched route is sent to the guidance guide unit 140. Thereafter, the sequence returns to step ST21, and the route guidance process is continued.

  If it is determined in step ST26 that the “No” button has not been pressed, the user is recognized to have left the selection operation, and then it is checked whether the user has returned to the route (step ST31). ). In other words, the guidance and guidance unit 140 determines whether the position indicated by the data representing the vehicle position mark sent from the map matching unit 120 is on the route indicated by the route data sent from the route search unit 130. Find out.

  If it is determined in this step ST31 that the route has not been returned, it is then checked whether or not a predetermined time has passed (step ST32). That is, by referring to a timer (not shown), the guidance / guidance unit 140 checks whether or not a predetermined time has elapsed since it was determined that the route deviated by Xm or more in step ST22. If it is determined in step ST32 that the predetermined time has not elapsed, it is then checked whether or not the vehicle has traveled a certain distance (step ST33). That is, the guidance / guidance unit 140 has changed by a certain distance after determining that the position indicated by the vehicle position data sent from the vehicle position detection unit 90 has deviated from the route by Xm or more in step ST22. Find out.

  If it is determined in step ST33 that the vehicle has traveled a certain distance, if it is determined in step ST31 that the vehicle has returned to the route, and if it is determined in step ST32 that a certain time has elapsed. In this case, the transit point selection message is deleted (step ST34). That is, the guidance guide unit 140 stops the process of sending drawing data representing the waypoint selection message to the output unit 18. As a result, the transit point selection message displayed on the monitor 2 is deleted.

  Next, route re-search is performed (step ST35). In this step ST35, it can be configured that the navigation device determines in advance whether to perform a re-search through the most recent waypoint or to perform a re-search without going through the most recent waypoint. Can be configured to select. Thereafter, the sequence returns to step ST21, and the route guidance process is continued.

  If it is determined in step ST33 that the vehicle has not traveled a certain distance, it is then checked whether the destination has been reached (step ST36). That is, the guidance guide unit 140 checks whether or not the position indicated by the vehicle position data sent from the vehicle position detection unit 90 matches the position set as the destination. If it is determined in step ST36 that the vehicle has not arrived at the destination, the output returns to step ST24, and the above-described processing is repeated.

  On the other hand, if it is determined in step ST36 that the vehicle has arrived at the destination, the transit point selection message is deleted (step ST37). The process in step ST37 is the same as the process in step ST34 described above. Thereafter, the route guidance process ends.

  As described above, according to the navigation device according to the first embodiment of the present invention, when a predetermined distance is deviated from the route to the nearest waypoint, the route place selection message indicating the departure is output. Since it is configured to be able to instruct whether or not to go through the most recent waypoint in response to this waypoint selection message, the handling of the most recent waypoint when deviating from the route can be determined by the user's will. Therefore, it is possible to provide a navigation device with excellent usability.
