Description

  The present invention relates to a navigation device mounted on a vehicle or the like.

  A normal in-vehicle navigation device is provided with a reroute function for re-searching the route from the point after departure to the destination when the vehicle deviates from the guidance route. However, when stopping at a highway service area or parking area, a reroute search is often performed due to departure from the guidance route, and the travel plan is often changed. Therefore, Patent Document 1 describes a technology of a navigation device that does not reroute even when deviating from the guidance route only in a specific stopover place set in advance in the navigation device.

Japanese Patent Laid-Open No. 10-281796

  However, with the above technique, it is only possible to realize a drop-in only in a specific situation preset in the navigation device (a situation in which the map data includes information indicating a specific situation). In other words, it cannot answer the need to stop by in accordance with the user's intention. As a specific example, there may be a case where it is necessary to guide a route to a point that deviates slightly from the original route (for example, a convenience store) because the user wants to take a break. Usually, in such a case, there are many cases where it is not desired to make a major change to the route guidance to the final destination. In the technique of Patent Document 1, since the user cannot set a stop-by place, such a need cannot be answered.

  An embodiment of the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic configuration diagram of an in-vehicle navigation device 100 to which an embodiment of the present invention is applied. As shown in the figure, the in-vehicle navigation device 100 includes an arithmetic processing unit 1, a display unit 2, a storage device 3, a voice input / output device 4, an input device 5, a wheel speed sensor 6, and a gyro sensor 7. , A GPS (Global Positioning System) receiver 8, an FM multiplex broadcast receiver 9, and a beacon receiver 10.

  The arithmetic processing unit 1 is a central unit that performs various processes. For example, the present location is detected based on information output from the various sensors 6 and 7 and the GPS receiver 8. Further, map data necessary for display is read out from the storage device 3 based on the obtained current location information. Further, the read map data is developed in graphics, and a mark indicating the current location is superimposed on the map data and displayed on the display unit 2. In addition, the map data stored in the storage device 3 is used to search for an optimum route (recommended route) that connects the starting point (current location) instructed by the user and the destination. Further, the user is guided using the voice input / output device 4 and the display 11.

  The display unit 2 is a unit that displays graphics information generated by the arithmetic processing unit 1, and includes a display 11 and a touch input detection device 12. The display 11 is composed of a CRT or a liquid crystal display.

  The touch input detection device 12 is a so-called touch panel that is mounted on the display side surface of the display 11 and transmits the display screen. The touch input detection device 12 specifies a touch position corresponding to the XY coordinates of the image displayed on the display 11, converts the touch position into coordinates, and outputs the coordinate. The touch input detection device 12 includes a pressure-sensitive or electrostatic input detection element.

  The storage device 3 includes a storage medium such as a CD-ROM, DVD-ROM, HDD, or IC card. In this storage medium, map data 310 and stop-by point data 330 are stored.

  FIG. 2 is a diagram showing the configuration of the map data 310. The map data 310 includes, for each mesh identification code (mesh ID) 311 which is a partitioned area on the map, link data 320 of each link constituting a road included in the mesh area.

  The link data 320 includes, for each link ID 321, coordinate information 322 of two nodes (start node and end node) constituting the link, road type information 323 including the link, link length information 324 indicating the link length, link The travel time 325 includes a link ID (connection link ID) 326 of a link connected to each of the two nodes. Here, by distinguishing the start node and the end node for the two nodes constituting the link, the upward direction and the downward direction of the same road are managed as different links. The link travel time 325 may be a link travel time associated with each condition such as date and weather.

  FIG. 3 is a diagram showing the configuration of the stop-point data 330. As shown in FIG. In the stop point data 330, each record includes a stop point identification code (stop point ID) 331, information for specifying a stop point such as a coordinate position (stop point specifying information) 332, and the facility of the stop point. Information (classification of stop points) 333 that classifies whether the facility is such is stored. The stop point specifying information 332 stores the coordinates of the position of the stop point on the map. Whether or not a certain point is a stop point can be determined from the coordinates of the node of the link and the stop point specifying information 332. The stop point type 333 is a content related to the type of stop point such as “restaurant”, “convenience store”, “drive-in”, “gas station”, and the like.

  Returning to FIG. The voice input / output device 4 converts the message to the user generated by the arithmetic processing unit 1 into a voice signal and outputs it. Also, a process of recognizing the voice uttered by the user and transferring the contents to the arithmetic processing unit 1 is performed.

  The input device 5 is a unit that receives instructions from the user. The input device 5 includes hardware switches such as a scroll key and a scale change key, a joystick, and the like.

  The sensors 6 and 7 and the GPS receiver 8 are used for detecting the current location (vehicle position) by the vehicle-mounted navigation device 100. The wheel speed sensor 6 measures the distance from the product of the wheel circumference and the measured number of rotations of the wheel, and further measures the angle at which the moving body is bent from the difference in the number of rotations of the paired wheels. The gyro 7 is configured by an optical fiber gyro, a vibration gyro, or the like, and detects an angle at which the moving body rotates. The GPS receiver 8 receives a signal from a GPS satellite and measures the distance between the moving body and the GPS satellite and the rate of change of the distance with respect to three or more satellites, thereby moving the current position, traveling speed, and traveling of the moving body. Measure orientation.

  The FM multiplex broadcast receiving device 9 receives rough current traffic information, regulation information, SA / PA (service area / parking area) information, parking lot information, weather information, etc. sent from the FM multiplex broadcast station as FM multiplex broadcast signals. Receive.

  The beacon receiving device 11 receives current traffic information, regulation information, SA / PA information, parking lot information, and the like sent from the beacon.

  FIG. 4 is a functional block diagram of the arithmetic processing unit 1.

  As illustrated, the arithmetic processing unit 1 includes a main control unit 101, a user operation analysis unit 102, a stop-by point guide unit 103, a route search unit 104, a route guidance unit 105, and a display processing unit 106. .

  The user operation analysis unit 102 receives a request from the user input to the input device 5, analyzes the request content, and controls each unit of the arithmetic processing unit 1 so that processing corresponding to the request content is executed. To do. For example, when the user requests a recommended route search, the display processing unit 106 is requested to display a map on the display 11 in order to set a destination. Further, it requests the route search unit 104 to calculate a route from the current location (departure location) to the destination.

  The stop point guide unit 103 sets a stop point designated by the user as a stop point, and requests the route search unit 104 and the route guide unit 105 to perform route search and route guidance to the point.

  The route search unit 104 uses the Dijkstra method or the like to search for a route that minimizes the cost (for example, distance and travel time) of a route connecting between two designated points (current location, destination, or stopover point).

  The route guidance unit 105 performs route guidance using the route searched by the route search unit 104. For example, the information on the route is compared with the information on the current location, and the voice input / output device 4 is used to inform the user by voice whether the vehicle should go straight before passing an intersection or the like. In addition, the route guiding unit 105 displays a direction to travel on the map displayed on the display 11 and notifies the user of the recommended route.

  The display processing unit 106 receives map data in an area where display on the display 11 is requested from the storage device 3, and at a specified scale and drawing method, roads, other map components, current location, destination, A map drawing command is generated so as to draw a mark such as an arrow for the recommended route. Then, the generated command is transmitted to the display 11.

  FIG. 5 is a diagram illustrating a hardware configuration example of the arithmetic processing unit 1.

  As illustrated, the arithmetic processing unit 1 has a configuration in which devices are connected by a bus 32. The arithmetic processing unit 1 includes a CPU (Central Processing Unit) 21 that executes various processes such as numerical calculation and control of each device, and a RAM (Random Access Memory) that stores map data, arithmetic data, and the like read from the storage device 3. ) 22, a ROM (Read Only Memory) 23 for storing programs and data, a DMA (Direct Memory Access) 24 for transferring data between the memories and between the memory and each device, and graphics drawing. In addition, a drawing controller 25 that performs display control, a video random access memory (VRAM) 26 that stores graphics image data, a color palette 27 that converts image data into RGB signals, and an A / D that converts analog signals into digital signals. Converter 28 and an SCI (Serial Communication Interface) that converts the serial signal into a parallel signal synchronized with the bus. ace) 29, a PIO (Parallel Input / Output) 30 that puts a parallel signal on the bus in synchronization with the bus, and a counter 31 that integrates the pulse signal.

  Each component and function described above is achieved by the CPU 21 executing a program loaded into the RAM 22 or ROM 23.

  [Description of Operation] Next, the operation of the in-vehicle navigation device 100 having the above-described configuration will be described.

  In the following, “touch” is expressed as a user's finger touching a point on the touch input detection device 12. Thereafter, the release of the user's finger from the touch input detection device 12 is referred to as “release”. In addition, changing and moving one touched point within the detection range of the touch input detection device without releasing the finger after “touching” (without releasing “release”) is called “slide”.

  “Double touch” means that the user “touches” (without “sliding”) and “releases” within a predetermined time quickly (within a predetermined time) twice. .

  The navigation device 100 according to the present embodiment includes two operation modes: a normal mode that realizes route guidance and the like included in a normal navigation device, and a stop-by point guidance mode that is unique to the present application.

  FIG. 6 is a flowchart showing the flow of the stop point guide process in the stop point guide mode.

  As shown in FIG. 7, the stop point guide unit 103 starts this flow when receiving a request for shifting to the stop point guide mode from the user via the touch input detection device 12.

  Specifically, in this embodiment, the touch input detection device 12 detects that the screen display of the main route 503 for guiding the route from the departure point 501 to the destination 502 is double-touched, and the user operation analysis unit The user operation analysis unit 102 transmits a stop point guide request to the stop point guide unit 103. Subsequently, the stop point guide unit 103 sets the scroll function at the time of accepting input to OFF (step S110). The reason for setting the scroll function to OFF is to set the position touched by the subsequent operation as a stop-in place. That is, when the scroll function is not turned off, the position touched in the subsequent operation is accepted as a scroll operation command as usual. This causes the display screen to be scrolled against the user's intention, making it impossible to set the stop-by location.

  An operation image when shifting to the stop-point guide mode is shown in FIG. 7 together with a screen image example.

  FIG. 7 shows a departure point 501, a destination 502, a main route 503 that is a guide route to the destination, and a current position 504. What is indicated by a broken line on this route 503 is a virtual indication of the user's finger touching the display 11.

  Next, the stop point guide unit 103 selects a stop point candidate within a certain distance from the current location of the host vehicle, requests the selected stop point candidate to the display processing unit 106, and causes the display 11 to display the candidate.

  Specifically, the stop point guidance unit 103 is based on the vehicle position detected by the various sensors 6, 7 or the GPS receiver 8 and refers to the map data 310 in FIG. The mesh ID 311 is acquired. Subsequently, the stop point guide unit 103 refers to the stop point data 330 shown in FIG. 3 and is adjacent to the acquired mesh (the adjacent here refers to the one that touches the mesh boundary and the mesh boundary does not touch the mesh boundary). Also, although the shortest distance between meshes is within a predetermined distance, it indicates both.) For the mesh, the stop point ID 331 and the stop point type 333 are acquired.

  The stop point guide unit 103 instructs the display processing unit 106 to display the acquired stop point on the display 11 as a stop point candidate. At this time, an icon object, which is image information corresponding to the stop point type 333, is displayed for each acquired stop point candidate (step S111).

  FIG. 8 is an example of a screen image displayed on the display 11 immediately after step S111 is performed. In FIG. 8, in addition to the main route 503 for guiding the route from the departure point 501 to the destination 502 by the display processing unit 106 and the current position 504 indicating the current location, a mesh including the own vehicle position or an adjacent mesh is displayed. Existing stop-point candidates 505a to 505e are displayed as POIs (Point of Interest) on the map by icon display.

  Next, the stop point guide unit 103 receives a stop point input from the user via the touch input detection device 12 (step S112).

  Specifically, first, the user operation analysis unit 102 detects that the user has touched with a finger on or near the line of the main path 503 shown on the display 11, and the touched coordinates are detected. To get.

  Subsequently, the user operation analysis unit 102 acquires, from the touch input detection device 12, the user's slide on the display 11 and the released coordinates.

  The user operation analysis unit 102 that has detected the input coordinates of the touch, slide, and release determines that the stop location designation operation has been performed when the touch, slide, and release information is given without excess or deficiency. The information is notified to the stop point guide unit 103.

  The stop point guide unit 103 detects the POI at a position corresponding to the position on the display 11 where the release has been performed, and specifies the stop point indicated by the user.

  FIG. 9 shows the operation image of step S112 together with a screen image example.

  FIG. 9 illustrates an example in which the display processing unit 106 displays the departure point 501, the destination 502, the main route 503 that is a guidance route to the destination, and the current position 504 on the display 11. In addition to this, an operation for designating the stop point candidate 505d as a stop point is also shown.

  Further, the stop point guide unit 103 specifies the specified stop point candidate and requests the route search unit 104 to search for a route. The route search unit 104 calculates a route search from the current location to the stop-by location using an algorithm such as a normal Dijkstra method. (Step S113).

  Furthermore, before starting the route guidance based on the stop route 507 calculated in step S113, the stop point guide unit 103 saves and stores the information of the main route 503 in the storage device 3. Also, the reroute function is set to off. (Step S114).

  In step S114, the information of the main route 503 is saved and stored in the storage device 3. The purpose of this processing is as a reference of the route to be returned when performing the return processing after the stop-by location guidance is completed as will be described later. It is necessary to save the file without deleting it.

  Similarly, in step S114, the purpose of setting the reroute function to OFF is to determine whether the stop route is rerouted or the main route is rerouted when the reroute is performed during the stopover guidance. It becomes clear and suppresses the possibility of significantly impairing the operability of the user. In some cases, the user may be confused during driving, so the reroute function is set to OFF in order to avoid the fear.

  Next, FIG. 10 shows a screen image at the time when step S114 is executed and the stop route guidance is started.

  In FIG. 10, the stop point accepted in the previous step S <b> 112 is set as a stop point by the stop point guide unit 103 and displayed on the display 11 by the display processing unit 106. Similarly, a stop route 507 reaching the stop location is displayed in a different expression from the main route 503, and an intersection 506a entering the stop route 507 from the main route 503 and an intersection 506b joining the stop route 507 to the main route 503 are provided. Displayed by the display processing unit 106.

  In FIG. 10, the stop point guide unit 103 deletes the other candidate stop locations 505 a to 505 c and 505 e that have not been selected from the screen display, but may continue to display without deleting them.

  Based on the route to the stop point searched in step S113, the stop point guide unit 103 requests the route guide unit 105 for route guidance.

  Specifically, when the stop point guide unit 103 finishes the process of step S114, the stop point guide unit 103 continues to hand over the stop route 507 obtained as a result of the search in step S113 to the route guide unit 105 to start route guidance. I ask you to.

  The route guidance unit 105 requested to guide the route starts route guidance according to the handed over stop route 507 (step S115). At this time, the route guiding unit 105 also displays the route 503 on the screen when performing the route guidance of the stop-by route 507.

  When step S115 is executed, the user refers to the route guidance shown in step S115 and drives for a stop.

If the route guidance unit 105 determines that the current location of the vehicle has arrived at the same point or in the vicinity of the stop location (in this embodiment, within 50 m from the stop location) (Y in S116), the route guide portion 105 stops that fact. It transmits to the point guide part 103. In response, the stop point guide unit 103 requests the route search unit 104 to search for the shortest route 508 to return to the main route 503. (Step S118)
Alternatively, even when the route guidance unit 105 has not arrived at the stop-by location as a result of the route guidance (N in S116), cancellation of the stop-point guide was accepted from the user via the touch input detection device 12 during the route guidance. Even in the case (Y in S117), the same processing as in step S118 is performed.

  FIG. 11 shows a user operation and a screen image when cancellation of stop-by point guidance is accepted (Y in S117).

  When the stop point guide unit 103 detects a double touch on the line indicating the main route 503 by the user via the touch input detection device 12, the stop point guide unit 103 receives an instruction to cancel the stop point guide, and then performs step S118. carry out.

  The stop point guide unit 103 that has performed step S118 requests the route guidance unit 104 to guide the route according to the route 508 searched in step S118. In addition, after the vehicle returns to the main route 503, the main control unit 101 is notified to start normal route guidance, and the reroute function that was turned off in step S114 for the stop point guidance, and off in step S110. The scroll function that has been set is restored, and the process is terminated (step S119). Thereafter, route guidance is performed by the standard navigation function.

  FIG. 12 shows a screen display on the display 11 immediately after step S118 is performed and step S119 is started. The display processing unit 106 displays the current position 504 on the drop-in path 507, and displays an intersection 506c, which is a junction of the return path 508 returning from the current position 504 to the main path 503 and the main path 503. The display processing unit 106 displays the return route 508 in a mode different from the main route 503.

  In FIG. 12, although the drop-in route 507 is canceled, it is indicated by a dotted line, but it is not displayed on the actual screen. Alternatively, only display may be performed as a route that is not selected.

  In addition, as shown in FIG. 13, when displaying the POI of the drop-in point candidate in the drop-in point input reception in step S112, a plurality of candidates within a narrow range such as drop-off point candidates α (509α) and β (509β) Since there is a high density, there is a case where the POI is inevitably displayed.

  In such a case, the stop point guide unit 103 lists all POIs that overlap or are adjacent to the selected POI (two stop point candidates α and drop point candidate β in FIG. 13) and pops up a list. indicate. Then, the user is made to touch-select one of the POIs from the list, and the selected POI is specified as a drop-in candidate designated by the user.

  This eliminates the need for the user to perform a touch operation strictly and accurately in an unstable vehicle.

  The embodiment of the present invention has been described above.

  According to the above-described embodiment, it is possible to easily and intuitively set the stop-by place guidance without greatly changing the route on the route to the destination. Further, even when the user cancels the guidance to the stop-off place or arrives at the stop-off place, the return route to the main route can be searched and guided.

  Thereby, the user can receive guidance to the destination and guidance to the stop-in place without largely changing the drive plan roughly determined at the time of departure.

  The present invention is not limited to the above embodiment. The above embodiment can be variously modified within the scope of the technical idea of the present invention.

  For example, the case where the stop point candidate is set in the stop point data 330 as a record has been described as an example, but the present invention is not limited to this. That is, as shown in FIG. 14, a stop point candidate editing unit 107 may be provided in the arithmetic processing unit 1 so that the user can add, edit, and delete a stop point candidate record. In that case, the stop-point candidate editing unit 107 executes a process of adding, editing, and deleting a record with respect to the stop-point data 330 stored in the storage device 3.

  Alternatively, as shown in FIG. 15, the arithmetic processing unit 1 may include a stop point candidate adding unit 108 that adds a point designated at the time of normal route guidance to a stop point candidate.

  In that case, during normal route guidance, the drop-in point candidate adding unit stores the drop-off point stored in the storage device 3 as the drop-off point candidate, the vehicle position or the point touched by the user on the display device 11. Processing to be added to the data 330 is performed.

  Also, when the number of stop points specified within a predetermined period for each stop point candidate is logged as a history and stored in the storage device 3, when the navigation device is first activated after the predetermined period has elapsed In addition, the history is read from the storage device 3, the priority is set so as to be displayed at the top of the drop-in point candidate display in the descending order of the number of times specified as the stop point, and the set priority is recorded in the storage device 3. It may be. When performing pop-up display or the like, the priority may be referred to and displayed from the highest priority.

  In this way, if the display can be changed according to the history, priority is given to places where users often stop even in dense areas where the number of drop-down point candidates is too large and the operation of selecting options becomes complicated. Can be displayed automatically. As a result, the user can smoothly select a stop point candidate without taking time and effort for the selection operation.

  In the above embodiment, an example in which the present invention is applied to a vehicle-mounted navigation device has been described. However, the present invention can also be applied to a navigation device other than a vehicle-mounted navigation device.
