  The invention of the route display processing program according to claim 9 is an acquisition means for acquiring state information relating to the state of the moving body, and the moving body is brought into a stopped state or a slow state based on the acquired state information. A discriminating means for discriminating whether or not there is a display control means for scrolling and displaying a map showing a route to a point designated by the user when it is determined that the moving body is in a stopped state or a slowing state; It is made to function as.

  The invention of the recording medium according to claim 10 is characterized in that the route display processing program according to claim 9 is recorded so as to be readable by a computer.

  Hereinafter, the best embodiment of the present application will be described with reference to the accompanying drawings. In addition, embodiment described below is embodiment at the time of applying this application with respect to the vehicle-mounted navigation apparatus mounted in the vehicle as an example of a mobile body.

  First, with reference to FIG. 1 etc., the structure and function of the vehicle-mounted navigation apparatus in this embodiment are demonstrated.

  FIG. 1 is a diagram illustrating a schematic configuration example of an in-vehicle navigation device according to the present embodiment.

  As shown in FIG. 1, the in-vehicle navigation device S includes a GPS (Global Positioning System) receiving unit 1, a sensor unit 2, a traffic information receiving unit 3, an information storage unit 4, a display unit 5, an audio output unit 6, and an operation unit. 7 and a system control unit 8 and the like.

  The GPS receiver 1 receives navigation radio waves output from GPS satellites arranged in the satellite orbit and orbiting the earth via an antenna (not shown), and detects position information (longitude and latitude) based on the received signals. The GPS data is output to the system control unit 8.

  The sensor unit 2 includes, for example, a speed sensor that detects the speed of the vehicle based on a vehicle speed pulse, a direction sensor (gyro sensor) that detects the traveling direction of the vehicle using geomagnetism, an acceleration sensor that detects the acceleration of the vehicle, A distance sensor for detecting the travel distance is provided, and each data (speed data, azimuth data, acceleration data, travel distance data, etc.) detected by these sensors is output to the system control unit 8. Yes.

  The traffic information receiving unit 3 has, for example, a VICS (Vehicle Information and Communication System) receiver, FM multiplex broadcasting, optical (infrared) beacons, radio waves installed on roads (for example, main highways and highways) (Quasi-microwave) Road traffic information transmitted from a beacon or the like (for example, information indicating a traffic jam section and a vehicle average speed (for example, 5 km / h to 10 km / h) in the section) is received and sent to the system control unit 8 It is designed to output.

  The information storage unit 4 includes, for example, a CD (Compact Disc) drive, a DVD (Digital Versatile Disc) drive, an HD (Hard Disk) drive, and the like. Data and programs (including the route display processing program of the present application) are read from a recording medium such as a ROM, a DVD-ROM, or an HD, and output to the system control unit 8. In addition, under the control of the system control unit 8, the HD drive stores (records) various data in the HD. The data and the program are stored and stored in a predetermined server connected to a communication network including the Internet and a mobile communication network (including a wireless base station), and transmitted from the server as appropriate. You may comprise so that it may output to the system control part 8 via the antenna and communication part which are not shown in figure.

  Here, the data stored in the HD or the like includes, for example, map data, link data, node data, guidance data, and travel history data, and data for prompting the user to input or select (for example, , Menu data) and the like.

  The map data includes map image data for displaying a map on the screen in the display unit 5, data indicating coordinates of each point (coordinates (X, Y) on the map corresponding to latitude and longitude), and the like. For example, a plurality of administrative boundary data indicating boundaries of a plurality of administrative divisions on the map (including addresses corresponding to the administrative divisions), road data indicating roads on the map (each road name, each intersection name, And the name of each junction (junction), etc., multiple facilities on the map (eg, gas stations, stores (convenience stores, restaurants, department stores, etc.), stadiums, amusement parks, stations, airports, ports, parking lots Etc.) multiple facility data (including the name of each facility, the type of facility (for example, the type of gas station, convenience store, parking, etc.), and the address of the facility), and It includes river shape data and showing the shape of a plan view like the mountain (including names and the like rivers and mountain), and the like.

  The road shown by the road data is composed of links as a plurality of line segments, and at least two links are connected by one node. This node corresponds to, for example, a connection portion including a contact point (a node) such as an intersection, a bending point, a branch point, a junction (junction), or an interchange of a toll road.

  The link data includes, for each link, the link ID of the link, the node IDs of two nodes to which the link is connected, the distance of the road corresponding to the link (distance of the road section), the attribute, and the direction (These information are associated with each link). The road attributes include, for example, information such as the width of the road, the number of lanes of the road, whether one-way or two-way, whether there is a right / left turn lane, or the like. Further, for each link, a link cost is set as a weight in consideration of the distance of the road corresponding to the link, the attribute of the road, and the like. For example, when the road distance is short or the road width is wide, the time required for traveling in the section is shortened, so the link cost is set to be small. Further, the link cost changes depending on traffic conditions such as traffic jam obtained by the traffic information receiving unit 3 (for example, in the case of traffic jam, the link cost corresponding to the link is set small). The node data includes, for each node, the node ID of the node, the coordinates of the node (coordinates (X, Y) on the map corresponding to the latitude and longitude), and the link of the link connected to the node. It has information such as ID.

  Furthermore, each node has a weight that represents the difficulty of moving the vehicle (straight, left or right turn, etc.) from the road corresponding to one link to the road corresponding to the other link via the connection corresponding to that node. A node cost is set as a splice. As an example, when a vehicle turns right from a wide road to a narrow road through an intersection, it is difficult to turn, so the node cost is set large.

  These link data, node data, etc. are searched for a recommended route to the set destination point (for example, the shortest distance route from the current point to the destination point, or the shortest time route from the current point to the destination point). Used in the case of.

  The guidance data includes image data, character data, voice data, and the like used for guidance when the vehicle is running.

  The display unit 5 includes, for example, a drawing processing unit, a buffer memory, and a display (for example, a liquid crystal display or an organic EL display). The drawing processing unit controls the map data under the control of the system control unit 8. Are expanded and drawn in the buffer memory and then displayed on the screen of the display. In addition, for example, instruction buttons for prompting various instructions to the user under the control of the system control unit 8 are also displayed on the screen.

  The display is composed of, for example, a touch panel type liquid crystal display and the like, detects a press by the user, and outputs an instruction signal corresponding to an instruction button for performing various instructions at the pressed position to the system control unit 8. It may be.

  The audio output unit 6 includes, for example, a DAC (digital / analog signal converter), an amplifier, a speaker, and the like. After A conversion, the signal is amplified by an amplifier and output as a sound wave from a speaker.

  The operation unit 7 has a plurality of instruction buttons (operation buttons) for receiving various instructions (for example, destination setting instruction, route search instruction, map scroll instruction, etc.) from the user, and is pressed by the user. An instruction signal corresponding to the instruction button is output to the system control unit 8. The operation unit 7 performs infrared communication with a remote control (not shown) provided with various operation buttons, receives an instruction signal from the remote control, and outputs it to the system control unit 8. Also good.

  The system control unit 8 includes a CPU having an arithmetic function, a working RAM, a ROM that stores various data and programs, and the like, and performs overall control of all the components in the navigation device S. Then, the CPU of the system control unit 8 reads and executes a program (including the route display processing program of the present application) stored in the information storage unit 4, for example, thereby obtaining the acquisition unit, the determination unit, the display control unit, and the like of the present application. Function to execute the processing described later.

  More specifically, for example, the system control unit 8 sets a destination point designated via the operation unit 7 from the user, and searches for a recommended route from the calculated current point to the destination point (the link described above). Based on the data and link costs, etc., by various known search processes), while scrolling the map along the recommended route centering on the current location (vehicle position) (scroll display accompanying the route guidance operation) The route guidance information is displayed on the screen of the display unit 5 or is output as sound from a speaker of the audio output unit 6. The system control unit 8 is based on the speed data, the azimuth data, the acceleration data, and the like from the sensor unit 2 and the GPS data from the GPS receiving unit 1 on the map corresponding to the latitude and longitude. (Coordinates (X, Y)) are calculated, but since this calculation method is well known, detailed description thereof will be omitted.

  Further, the system control unit 8 acquires state information related to the state of the vehicle, and based on the acquired state information, whether or not the vehicle is in a stopped state (stopped state in the present embodiment) or a slow-down state. If it is determined that the vehicle is in a stopped state or a slowing state, a map showing a route to a point designated by the user is scroll-displayed (also referred to as scroll display for prior confirmation or auto-scroll display). It is supposed to let you.

  Here, examples of the state information related to the state of the vehicle include speed data from the sensor unit 2 and road traffic information from the traffic information receiving unit 3.

  When the speed data from the sensor unit 2 is used, if the vehicle speed is 0 km / h, it is determined that the vehicle is in a stopped state. If the vehicle speed is greater than 0 km / h and less than 5 km / h, the vehicle is It is determined that the vehicle is in a slow state. Further, when road traffic information from the traffic information receiving unit 3 is used, if the current point is located in a traffic jam section and the average vehicle speed in the section is, for example, 5 km / h or less, the vehicle is stopped or slowed down. It is determined that it is in a state. Such determination of the stop state or the slow state may be performed by other methods. For example, an on / off signal of a lighting button of a hazard lamp provided in the vehicle is transmitted via an interface (not shown). It is configured to input to the system control unit 8 and configured to determine that the vehicle is in a stopped state or a slowing state when an ON signal is input when the lighting button is pressed by the user. Also good. Further, the vehicle may be determined to be in a stopped state or a slowing state based on the state of the gear of the vehicle (for example, a parking state or the like).

  Examples of the point designated by the user include a set destination point or a facility point located around the current point. Examples of the facility located around the current location include a facility with the shortest distance from the current location or a facility with the shortest time.

  In addition, the scroll display of the map showing the route to the point (scroll display for prior confirmation) is executed immediately when it is determined that the vehicle is in the stopped state or the slowing state, and the vehicle is in the stopped state. Or, when it is determined that the vehicle is in a slow running state, there is a case where it is executed after waiting for designation of a point from the user. In the case where the system control unit 8 is executed after waiting for designation of a point from the user, for example, the system control unit 8 prompts the user to start a scroll display (for example, displays information prompting the start instruction in the display unit 5). Display on the screen (for example, display an instruction button or the like for designating the above-mentioned point), or output as a sound from a speaker in the audio output unit 6), and an instruction accompanying the designation of the point from the user is the operation unit 7 or the like If there is, the scroll display is started.

  In order to avoid this, the vehicle may be determined to be in a stopped state or a slow-down state even when the vehicle speed is reduced to, for example, 5 km / h or less due to a brake operation during normal driving. It is desirable to prompt the user to start scroll display after a predetermined waiting time (for example, about 5 seconds) has elapsed since the determination that the vehicle is in a stopped state or a slow-down state.

  Furthermore, after determining that the vehicle is in the stopped state or the slowing state, the system control unit 8 determines whether or not the stopped state or the slowing state has been eliminated. Control is performed so that the scroll display is terminated and the display state immediately before the determination is restored (automatic return).

  Next, with reference to FIG. 2 thru | or FIG. 4, etc., operation | movement of the vehicle-mounted navigation apparatus S in this embodiment is demonstrated.

  FIG. 2 is a flowchart illustrating an example of processing in the system control unit 8. FIG. 3 is a diagram showing a display screen example in the display unit 5. FIG. 4 is a conceptual diagram for explaining scroll display of a map to be scroll-displayed (scroll display for prior confirmation).

  The process shown in FIG. 2 is started when the power source of the vehicle-mounted navigation device S is turned on, for example.

  In step S1, various instruction buttons such as a map 51 and a menu button 61 as shown in FIG. 3A, for example, are displayed on the display of the display unit 5, and the destination is specified according to instructions from the user (designation of various instruction buttons). Setting, route search / guidance processing, and the like are performed. In the example of FIG. 3A, a vehicle mark 52 is displayed at a position (approximately the center) corresponding to the current point on the map 51. Further, the map 51 is scroll-displayed so that the vehicle mark 52 appears to travel along the road 53, for example, as the vehicle actually travels. The menu button 61 is a button for transitioning to a screen on which the user performs various settings, and the user can perform destination setting, route search setting, and the like from the transitioned screen.

  In step S2, the system control unit 8 acquires state information (for example, speed data) regarding the state of the vehicle from the sensor unit 2, for example, as described above, and the vehicle is stopped or slowed based on the acquired state information. When it is determined whether the vehicle is in a stopped state or not in a slow state (for example, during normal travel) (step S2: NO), the process returns to step S1, and the vehicle is stopped or When it is determined that the vehicle is in a slow state (for example, when the vehicle is parked or waiting for a signal or when there is a traffic jam) (step S2: YES), time counting is started, and the process proceeds to step S3.

  In step S3, the system control unit 8 determines whether or not a standby time (for example, 5 seconds) has elapsed since the start of the time count, and when determining that it has not elapsed (step S3: NO), If the process proceeds to step S4 and it is determined that the time has elapsed (step S3: YES), the process proceeds to step S5.

  In step S4, the system control unit 8 acquires state information (for example, speed data) regarding the state of the vehicle as described above, and based on the acquired state information, has the vehicle stopped state or slow-down state been resolved? If it is determined whether it has not been canceled or not (step S4: NO), the process returns to step S3, and it is determined that it has been canceled (for example, when the traffic light is changed to blue and the driving is resumed). (Step S4: YES), the process returns to Step S1 (Note that when returning to Step S1, the time count of the waiting time is reset to “0”, and so on).

  In step S5, for example, as shown in FIG. 3B, the system control unit 8 displays instruction buttons 62 to 66 for designating the points on the map 51, thereby scrolling the user. Prompt for start instructions. In other words, after the standby time has elapsed since the determination that the vehicle is in the stop state or the slow speed state, the user is prompted to start scroll display.

  In the example of FIG. 3B, the destination instruction button 62 is displayed. However, the destination instruction button 62 is not displayed when the destination is not set in step S1 (in other words, the destination instruction button 62). Displayed only when the ground is set, the recommended route is searched, and the route is being guided). In the example of FIG. 3B, a gas station instruction button 63, a convenience store instruction button 64, a parking area instruction button 64, and a station instruction button 65 are displayed. Which kind of instruction button is displayed? Can be arbitrarily set by the user.

  Next, the system control unit 8 determines whether or not the user has given an instruction to start scroll display (here, any of the instruction buttons 62 to 66 has been pressed) (step S6). (Step S6: NO), state information (for example, speed data) related to the state of the vehicle is acquired as described above, and whether or not the stop state or slowing state of the vehicle has been resolved based on the acquired state information. If it is determined (step S7) and it is determined that it has not been released (step S7: NO), the process returns to step S6, and if it is determined that it has been released (step S7: YES), the process returns to step S1 (that is, Even if the instruction buttons 62 to 66 are displayed, they are reset if not pressed).

  Then, when there is a scroll display start instruction, for example, when the destination instruction button 62 is pressed (step S6: YES), the system control unit 8 determines the route to the destination point specified by the start instruction. The displayed map is scroll-displayed on the screen of the display unit 5 (step S8).

  For example, as shown in FIG. 4, the system control unit 8 displays the map screen, for example, 71 → 72 → 73 in FIG. 4 so that the vehicle mark 52 travels virtually along the road 53 to the destination point. Scroll with 74 → 75 → 76 → 77. Such scroll display is repeated until it is determined in step S9 that the vehicle stop state or slow-down state has been resolved (step S7: NO). During this time, for example, when the vehicle mark 52 reaches the destination point (FIG. 4). In the case of the display of the map screen 77 in the middle), the display returns to the display of the map screen 71, and the same scroll display is performed (the scroll (auto scroll) for the prior confirmation to the destination point is repeated). Thereby, the user can grasp the route to the set destination quickly and efficiently in a short time.

  In step S5, a scroll stop button for stopping the map scrolling is displayed. When the scroll stop instruction button is pressed by the user during the scrolling, the map scrolling is stopped (for example, FIG. 4). The user can confirm the details of the area in the middle of the destination. In step S5, when the scroll of the map is stopped halfway, a scroll pause button for automatically restarting the scroll after a few seconds is displayed, and the scroll pause instruction button is pressed by the user during the scroll. However, if the configuration is such that the scrolling of the map is paused, but the scrolling is resumed after a few seconds (for example, after 2 seconds), the user can check the details of the area in the middle of the destination. In addition, the scrolling can be resumed without troublesome operations.

  Further, when the vehicle mark 52 enters a traffic jam section of the road while the map is scrolling (this information is obtained from the traffic information receiving unit 3) (for example, the road shown in the map screen 74 shown in FIG. For example, if it is configured to display information indicating that it has entered a traffic jam (for example, “It has entered a traffic jam”) or to output audio, the user can grasp the traffic jam section at a glance. Can be more effective.

  On the other hand, when the gas station instruction button 63 in FIG. 3B is pressed, the system control unit 8 refers to, for example, map data and is located within a predetermined radius (for example, 2 km) from the current location. Search all gas stations (search using the type associated with each facility as a key), calculate the distance (or required time) from the current location to each searched gas station, and the shortest distance One gas station located at (or the shortest time) is selected, and a map showing the route to the selected gas station is scroll-displayed on the screen of the display unit 5 as described above (other instruction buttons 64- The same applies to 66). This allows the user to quickly and efficiently know the route from the current location to the nearest gasoline stunt, station, convenience store, etc. while driving (regardless of whether the destination is set). can do.

  If it is determined in step S9 that the vehicle stop state or slowing-down state has been resolved (step S9: YES), for example, by changing to a green light and starting the vehicle, the system control unit 8 ends the scroll display. The display state immediately before the determination (for example, the map screen 71 where the vehicle mark 52 is located at the current point on the map) is returned (automatic return), and the process returns to step S1.

  As described above, according to the above-described embodiment, the state information related to the state of the vehicle is acquired, and based on the acquired state information, it is determined whether the vehicle is in a stopped state or a slow-down state, and the vehicle When it is determined that the vehicle is in the stopped state or the slowing state, the map showing the route to the point designated by the user is scroll-displayed (scroll display for prior confirmation). The user can grasp the route to a desired point more efficiently and in a short time without operating. In addition, when it is determined that the moving body is in the stopped state or the slowing state, when the stopped state or the slowing state is canceled, the scroll display is ended, and the display state immediately before the determination is configured so that it is restored. The scroll display can be restored without any troublesome operation by the user. Therefore, for example, a short time such as waiting for a signal can be used effectively.

  When it is determined that the moving body is in the stopped state or the slowing state, an instruction button for designating a point is displayed, the user is prompted to start scroll display, and the user presses the instruction button to Since it is configured to start the scroll display of the map showing the route to the point corresponding to the instruction button when an instruction is given, the user can efficiently confirm the route to the desired point with one action. it can. For example, in the operation while caring for the signal, an operation error such as a pressing error can be considered, but the scroll display is started only by the user pressing the instruction button newly displayed, and the end (release) is automatically performed. Since this is done, the user can make a smooth confirmation.

  In the above embodiment, an example in which the route display device and the route display method of the present application are applied to the vehicle navigation device S mounted on the vehicle is shown, but the present invention is not limited to this. For example, the present invention is applied to a communication navigation system configured to include a communication navigation terminal and a communication center apparatus to which the communication navigation terminal is connected via an antenna and a mobile communication network (including a radio base station). Is possible. The present application is also applicable to other electronic devices that are mounted on vehicles and that can acquire information indicating the current position and display it on the screen.

  Further, in the above embodiment, the case where a vehicle is used as an example of a moving body has been described. However, the present invention is not limited to this. For example, a pedestrian or a bicycle is used as an example of a moving body. The present application is applied to a portable terminal (for example, a mobile phone, a PDA (Personal Digital Assistant), a PHS (Personal Handyphone System), or a notebook PC (Personal Computer)) possessed by a driver (or installed on a bicycle). It may be applied. In addition, the present application may be applied to a navigation device mounted on an aircraft, a ship, or the like as an example of a moving body.
