  Hereinafter, the display device, the control method of the display device, and the program of the present invention will be described. In each of the following embodiments, an on-vehicle device 1 mounted and used in a vehicle (mobile body) is exemplified as the display device.

First Embodiment
FIG. 1 is a block diagram showing the hardware configuration of the in-vehicle apparatus 1. The in-vehicle device 1 includes a GPS (Global Positioning System) receiver 11, a self-contained navigation sensor 12, a map database (hereinafter referred to as "map DB") 13, a network communication unit 14, a control unit 15, a touch panel 16, and a speaker 17. Prepare.

  The on-vehicle device 1 may be a so-called car navigation device that is retrofitted after vehicle shipment, or may be incorporated in a vehicle control system. Moreover, you may function as a car navigation apparatus by installing portable terminals, such as a smart phone, in a vehicle. Furthermore, the touch panel 16 and the speaker 17 do not necessarily have to be integrated with the in-vehicle apparatus 1, and may have a configuration independent of the in-vehicle apparatus 1.

  The GPS receiver 11 receives GPS information (including position information indicating the current position and time information indicating the current time) from the GPS satellites 20. The self-contained navigation sensor 12 comprises an angle sensor and a distance sensor (both not shown), and is used in combination with the GPS receiver 11 to specify the vehicle position. The map DB 13 stores map data for performing route guidance. In the present embodiment, the map data includes speed limit information of each road, traffic regulation information (traffic regulation according to time zone, one-way traffic, etc.).

  The network communication unit 14 communicates with an information providing server 30 built on a network such as the Internet via a wireless repeater (not shown). In this embodiment, it is mainly used for reception of road traffic information (traffic congestion information, temporary traffic regulation information by construction, etc.). The speed limit information and the traffic restriction information included in the map data, and the road traffic information acquired from the information providing server 30 are collectively referred to as "road information" hereinafter.

  The control unit 15 includes a central processing unit (CPU) 15a, a read only memory (ROM) 15b, and a random access memory (RAM) 15c. The CPU 15a is a central processing unit and performs various arithmetic processing. In the present embodiment, display control of the route guidance screen as shown in FIGS. 4 and 5 is mainly performed. Details will be described later. The ROM 15 b stores a control program and control data for the CPU 15 a to perform various arithmetic processing. The RAM 15 c is also used as a work area when the CPU 15 a performs various arithmetic processing. The touch panel 16 displays various setting screens in addition to the route guidance screens as shown in FIGS. 4 and 5. The speaker 17 outputs voice route guidance information.

  The map DB 13 may be provided in the information providing server 30, and map data and its update data may be received through the network communication unit 14. Also, the control program of the ROM 15 b may be executed by the information providing server 30. That is, the on-vehicle apparatus 1 may be operated using cloud computing technology.

  Next, the functional configuration of the in-vehicle apparatus 1 will be described with reference to FIG. The in-vehicle apparatus 1 includes, as main functional components, a destination setting unit 110, a destination acquiring unit 120, a route searching unit 130, a calculating unit 140, a time operation unit 150 (operation unit), and a display control unit 160.

  The destination setting unit 110 sets a destination by the user operating the touch panel 16. The destination acquisition unit 120 acquires the destination set by the destination setting unit 110. The route search unit 130 searches for a guide route (moving route) to the destination acquired by the destination acquisition unit 120, using the current location as the departure location. The route search unit 130 takes into consideration the road information acquired from the map DB 13 and the information providing server 30, and the search conditions (toll road priority, road width priority, etc.) preset by the user on the setting screen (not shown). Search the guidance route.

  The calculation unit 140 calculates an estimated arrival time for one or more arbitrary points (hereinafter, referred to as “one or more arbitrary points”) on the guide route searched by the route search unit 130. FIG. 3A is a diagram showing an example of the calculation result by the calculation unit 140 when the calculation process is performed at the departure place (at the time of setting the destination). In this case, a starting point ("point 0") is set as a starting point, and an arbitrary point is set at a predetermined distance interval to the destination. In the example of the figure, four arbitrary points from "point +1" to "point + 4" are set. The calculator 140 calculates estimated arrival times for these four arbitrary points. The “estimated arrival time” means a time when the vehicle is estimated to reach each optional point (pass each optional point). That is, in the same figure, "0:30", "0: 50", "1: 20", and "1: 40" indicate estimated arrival times of "point +1" to "point + 4", respectively. In addition to these arbitrary points, the calculation unit 140 calculates the estimated arrival time of the destination. “2:00” shown in the figure is the estimated arrival time of the destination. In addition, the calculation unit 140 calculates each estimated arrival time in consideration of the road information around the guide route acquired from the map DB 13 and the information providing server 30.

  FIG. 3B is a diagram showing an example of calculation results regarding an arbitrary point in the past when calculation processing is performed in the middle of route guidance. Even when the calculation processing is performed in the middle of the route guidance, the calculation processing from the current location to the destination is the same as that shown in FIG. On the other hand, with regard to an arbitrary point in the past, the current position (“point 0”) is set as a starting point, and an arbitrary point is set back at a predetermined distance interval to the departure point. In the example of the figure, three arbitrary points from "point-1" to "point-3" are set. The calculation unit 140 calculates estimated arrival times for these three arbitrary points. In addition, the "estimated arrival time" in the past means a time when it is estimated that the vehicle has reached each optional point (they have passed each optional point). In the figure, “11:30”, “11:10”, and “10:40” indicate estimated arrival times of “point-1” to “point-3”, respectively. In addition, about the departure place, it becomes the start time of route guidance ("10:00"). The start time of the route guidance is information stored in the RAM 15 c at the start of the route guidance. The calculation unit 140 calculates each estimated arrival time for an arbitrary point in the past, taking into consideration the start time of route guidance as well as road information around the guidance route.

  It returns to the explanation of FIG. The time operation unit 150 designates a time by performing an operation on the time control bar screen 41 b (time control bar) included in the route guidance screen. Further, the display control unit 160 displays the position of the vehicle at the time designated by the time operation unit 150 on the map screen included in the route guidance screen based on the calculation result of the calculation unit 140. Here, the configuration of the route guidance screen will be described.

  FIG. 4 is a view showing an example of a route guidance screen displayed on the touch panel 16. The route guidance screen comprises an upper screen portion 41 and a lower screen portion 42, and the lower screen portion 42 displays a map screen. The display control unit 160 displays the guidance route 61 with colored lines on the map screen and displays a mark (hereinafter referred to as "vehicle current position P1") indicating the current position of the vehicle on the guidance route 61. . Display control unit 160 also displays a mark (hereinafter referred to as “vehicle estimated position P3”) indicating the position of the vehicle estimated to arrive at the time designated by time operation unit 150 on guidance route 61 similarly. (See FIG. 5. In FIG. 4, it is not shown because it is out of the display range). Further, the guidance route 61 displays the toll road portion and the other roads in different colors. In the figure, reference numeral 61a indicates a toll road portion.

  On the other hand, in the upper part 41 of the screen, the current date and time screen 41a is disposed on the left side, and the time control bar screen 41b is disposed on the right side. The current date and time screen 41 a displays the current date and time based on time information included in the GPS information received from the GPS satellite 20. In the time control bar screen 41b, a scale indicating time is attached to the time axis 51, and four types of marks (marks M0 to M3) indicated by triangles are arranged. Mark M0 indicates departure time, mark M1 indicates current time, mark M2 indicates estimated destination arrival time, and mark M3 indicates designated time. Further, on the time axis 51, a colored bar 51a indicating the estimated passing time zone of the toll road is superimposed and displayed. The time operation unit 150 specifies a time by moving the mark M3 along the time axis 51 (in the horizontal direction in the drawing). The mark M3 is disposed at a position (the same position as the mark M0) indicating the departure time at the start of the route guidance (see FIG. 4).

  FIG. 5 is a diagram showing a change of the vehicle estimated position P3 accompanying the operation of the time control bar screen 41b. For example, when mark M3 is moved in the direction of arrow 71 from the position shown by a dotted line to the position shown by a solid line (when a drag operation is performed), vehicle estimated position P3 gradually along guide route 61 along with the operation. I will move. That is, the estimated vehicle position P3 changes in accordance with the movement amount (moving speed) of the mark M3 on the time axis 51 from the estimated vehicle position P3 indicated by the dotted line to the estimated vehicle position P3 indicated by the solid line.

  Thus, the user designates an arbitrary time by moving the mark M3 on the time control bar screen 41b. In addition, the designation of the time can designate the future and the past time with reference to the current time indicated by the mark M1. In this embodiment, time designation can be performed in a range from the departure time (see the mark M0 in FIG. 4 and FIG. 5) to the estimated destination arrival time (see M2 in FIG. 4 and FIG. 5).

  As described above, according to the first embodiment, in order to display the position of the vehicle at the time designated by the user (vehicle estimated position P3) on the map screen, the user Can know where it is located. Further, since it is possible to specify the time by operating the time control bar screen 41b, it is possible to confirm the position change of the vehicle estimated position P3 with a fine resolution (continuously).

  In addition, the following modification is employable. FIG. 6 is a block diagram showing a functional configuration of the in-vehicle apparatus 1 according to the modification of the first embodiment. The on-vehicle apparatus 1 according to the present modification has a configuration in which a storage unit 170 is added to the functional configuration (see FIG. 2) of the above-described embodiment. The storage unit 170 stores the traveling history of the vehicle (mobile body) in a predetermined storage area (such as the RAM 15 c) of the in-vehicle device 1. Here, the "traveling history" refers to information indicating the position of the vehicle recorded intermittently. "Intermittent" may be regular (predetermined time interval) or a predetermined distance interval. Further, the configuration may be such that the position of the vehicle is recorded when a predetermined condition based on the traveling state of the vehicle (such as stopping of the vehicle or sudden steering operation) is satisfied. In the predetermined storage area, old data is sequentially erased as new data is recorded.

  On the other hand, the calculation unit 140 of this modification calculates the estimated arrival time of the vehicle in the future. That is, the estimated arrival time of the vehicle in the past is not calculated. Further, the display control unit 160 of this modification displays the position of the vehicle in the future based on the calculation result of the calculation unit 140 as in the above embodiment, and stores the position of the vehicle in the past in the storage unit 170. Display based on the travel history recorded. As described above, according to the present modification, since the position of the vehicle in the past is displayed on the route guidance screen based on the actual travel history, accurate information can be notified to the user. Note that “the position of the vehicle in the past” may be displayed for the area from the departure point to the present point, or for the range allowed by the storage capacity of the predetermined storage area before the present point regardless of the departure point It is good.

  Moreover, although the destination acquisition part 120 of said embodiment acquired the destination set by the destination setting part 110, you may acquire the destination set by the portable terminal etc. FIG. In this case, the route search unit 130 may search for a guide route from the departure place set by the portable terminal or the like to the destination. In addition, the calculation unit 140 may calculate the estimated arrival time for one or more arbitrary points on the guidance route from the departure point to the destination, or one or more arbitrary points on the guidance route from the current location to the destination. .

  Moreover, although the calculation part 140 of said embodiment set the arbitrary point in the past in the range of the departure place-the present location, you may set the arbitrary point in the past including the place before the departure place irrespective of the departure place. . In this case, it may be set in the range from the current position to the position of the vehicle a predetermined distance before the current position to the current position, or may be set in the range from the position of the vehicle at the time a predetermined time before the current time to the current position.

  In addition, although the calculation unit 140 of the above embodiment calculates the estimated arrival time for one or more arbitrary points set at predetermined distance intervals on the guidance route, the estimated arrival times may not necessarily be equal intervals. For example, when there is a traffic congestion section or a vehicle traffic regulation section, the start point and the end point thereof are set as arbitrary points, and for the traffic congestion section or the vehicle traffic regulation section, the number of arbitrary points set in the section is increased. It is conceivable to change the interval between arbitrary points according to the speed limit.

  Moreover, although the calculation part 140 of said embodiment calculated the estimated arrival time in consideration of the road information around the guidance route | path of a vehicle, you may include the travel information of each vehicle in the said road information. Here, “travel information of each vehicle” refers to travel information obtained from a vehicle that can communicate with the information providing server 30. The information providing server 30 receives the traveling information (vehicle position, traveling route, traveling speed, etc.) as needed from each vehicle that has partnered with the traveling information providing system, thereby determining the presence or absence of traffic congestion or traffic regulation. The traffic regulation information is provided to each vehicle (in-vehicle device 1). As described above, by calculating the estimated arrival time in consideration of the travel information of each vehicle, highly reliable calculation results can be expected.

  In addition, although the time operation unit 150 of the above embodiment specifies the time using the time control bar screen 41b, other “operation elements whose designated value changes continuously” may be used. As an example of “an operator whose designated value changes continuously”, one having a designated value changing according to the depression duration of a button, one having a designated value changing according to the amount of rotation of a knob, and the like can be considered.

  Further, in addition to the “operation element whose designated value changes continuously”, the time may be designated by, for example, numerical input or selection from among a plurality of candidates. Further, instead of using the touch panel 16 as an operator, another operator (including an operator physically provided) mounted on the in-vehicle apparatus 1 or an operator provided separately from the in-vehicle apparatus 1 May be used. Regarding the latter, a remote controller attached to the in-vehicle apparatus 1 or a portable terminal equipped with a communication function (infrared communication function, short distance wireless communication function, etc.) and a control function of the in-vehicle apparatus 1 can be considered.

  Moreover, although the display control part 160 of said embodiment displayed the position (vehicle estimated position P3) of a vehicle on the guidance route 61 shown on the map, it is not necessary to necessarily display a map. For example, the map may be omitted, and the position of the vehicle may be shown on a diagram simply showing the guidance route 61. Also, the position of the vehicle need not necessarily be displayed on the guide route 61 to the destination, and the position of the vehicle may be displayed on the moving route of the vehicle determined by some conditions. In other words, it is not necessary to set a destination. The "some conditions" in this case are the traveling direction of the vehicle, the past travel history, user settings (such as toll road priority) and the like. For example, from the traveling direction of the vehicle, it is possible to identify several routes that the vehicle can move, and display the position of the vehicle on all the routes according to the specification of the time by the user. In addition, a past travel history may be stored, a route with a high passing frequency of the vehicle may be automatically selected, and the position of the vehicle may be displayed on the selected route. Further, the moving route of the vehicle may be automatically selected in accordance with user settings such as toll road priority, and the position of the vehicle may be displayed on the selected route.

  In the above embodiment, as shown in FIG. 5, when the movement of the vehicle estimated position P3 by the operation of the mark M3 is within the display range of the lower portion 42 (map screen), the map screen is not scrolled. However, the map screen may be scrolled along with the movement of the vehicle estimated position P3 (for example, so that the vehicle estimated position P3 is always positioned at the center of the map screen).

  Also, the scale of the map screen may be automatically changed in accordance with the amount of operation of the mark M3. For example, when the map screen is displayed in detail, if the operation amount of the mark M3 becomes large, the screen scroll amount increases and hinders visibility. Therefore, the scale of the map screen is increased for wide area display and the screen scroll amount is reduced. Also good. Also, the scale may be determined so that screen scrolling is not necessary. That is, the movement start point and the movement end point of the vehicle estimated position P3 may be set to the smallest scale that can be included in the display range of the map screen.

Second Embodiment
Next, a second embodiment of the present invention will be described with reference to FIGS. In the first embodiment described above, the position of the vehicle at the designated time is displayed, but in the present embodiment, peripheral information of the vehicle is displayed. Hereinafter, only differences from the first embodiment will be described. In the present embodiment, the same components as those of the first embodiment are denoted by the same reference numerals, and the detailed description thereof is omitted. Moreover, the modification applied about the component similar to 1st Embodiment is applied similarly about this embodiment.

  The in-vehicle apparatus 1 according to the present embodiment has the same configuration as the functional configuration (see FIG. 2) of the first embodiment, and thus the illustration thereof is omitted. However, the display control unit 160 according to the present embodiment is based on the calculation result of the calculation unit 140, the position of the vehicle (moving object) at the time designated by the time operation unit 150 (operation unit), and the surrounding information of the vehicle And. Further, along with the operation of the time operation unit 150 (the operation of the mark M3 on the time control bar screen 41b), the position of the vehicle (vehicle estimated position P3) is moved and the surrounding information of the vehicle is changed. Further, the display control unit 160 according to the present embodiment acquires, from the information providing server 30, display data (including image data of a facility icon to be described later) for causing the touch panel 16 to display peripheral information.

  Peripheral information refers to facility information (e.g., restaurant, retail store, parking lot, leisure facility, etc.), congestion information, weather information, and the like. Here, display control of facility information and traffic congestion information will be described by giving a specific example. 7 and 8 are diagrams showing display examples of facility information. In both figures, the facility icons 81 to 84 are displayed as facility information.

  In the example of FIG. 7, the mark M3 designates around 10:30 on the time control bar screen 41b (the vehicle estimated position P3 is located on the right side of the map screen), and four facility icons 81 to 84. Out of the three facility icons 81 to 83 are colored, and the facility icon 84 is outlined. Here, the colored display means that the facility is in a closed state (out of business hours, closing hours, regular holidays, etc.). In particular, in the present embodiment, in the case of a regular holiday (in the closed state all day), the message information 83a to that effect is displayed in a balloon. In addition, the white display means that the facility is in an open state (during business hours, opening hours, etc.).

  FIG. 8 shows a display example when the mark M3 on the time control bar screen 41b is moved to a position specifying 11:30. In this state, the vehicle estimated position P3 is located on the left side of the map screen, and the facility icon 83 of the four facility icons 81 to 84 is colored and the facility icons 81, 82, 84 are white. That is, as compared with the state shown in FIG. 7, the facility icons 81 and 82 change from colored display to whiteout display. This means that at 10:30, the facilities corresponding to the facility icons 81 and 82 were in the closed state, but at 11:30, they changed to the open state. Note that when the display mode of each facility icon 81, 82 changes, the designated time of the mark M3 is changed to each facility icon 81, 82 while the mark M3 moves from the position shown in FIG. 7 to the position shown in FIG. It is when the open start time of the corresponding facility has passed.

  In the examples of FIGS. 7 and 8, the facility information is displayed by an icon indicating each facility, but character information such as a facility name or a facility introduction may be displayed near the icon. Further, the identifier of each facility may be added to the icon and displayed, and the detailed information may be displayed together with each identifier in another area of the map screen.

  Further, the open / close of the facility icon may be distinguished by changing the display form of the icon such as the display color or the icon shape, or changing the content of the supplementary message, in addition to the white / colored display.

  Moreover, in the example of FIG. 7 and FIG. 8, all (the all of the facility icons 81-84) of the display range of the map screen (screen lower part 42) were changed as periphery information of the vehicle (vehicle estimated position P3) at designated time. However, the scope of the peripheral information of the vehicle may be narrowed. For example, in the example of FIG. 7, the facility icons 83 and 84 are hidden or displayed normally (display does not change with designated time), and in the example of FIG. 8, the facility icon 81 is hidden or displayed normally. Control can be considered.

  Further, in the case of a configuration in which the map screen is scrolled along with the movement of the vehicle estimated position P3, the range displayed on the map screen together with the vehicle estimated position P3 may be used as the peripheral information of the vehicle. That is, in this case, the entire range displayed on the map screen is the peripheral information of the vehicle.

  Subsequently, display control of traffic jam information will be described with reference to FIGS. 9 and 10. In both figures, congestion sections 91 and 92 are displayed as congestion information. The traffic jam information is displayed by periodically receiving road traffic information measured in real time from the information providing server 30. In the example of FIG. 9, the mark M3 designates around 10:30 on the time control bar screen 41b (the vehicle estimated position P3 is located on the right side of the map screen), and the congestion section 91 is displayed as a solid line. The traffic congestion section 92 is indicated by a dotted line. Here, the solid line display means that the congestion degree is high, and the dotted line display means that the congestion degree is low. The degree of congestion is determined according to the length of the congestion, the distance traveled per unit time, and the type of congestion (accident congestion, construction congestion, etc.).

  FIG. 8 shows a display example when the mark M3 on the time control bar screen 41b is moved to a position specifying 11:30. In this state, as compared with the state shown in FIG. 9, the congestion section 91 changes from the solid line display to the dotted line display, and the congestion section 92 is not displayed. This means that the degree of traffic congestion in the traffic congestion section 91 is lowered and the traffic congestion in the traffic congestion section 92 has been eliminated.

  In the examples shown in FIGS. 9 and 10, the section lengths of the traffic congestion sections 91 and 92 are not changed, but the section lengths may be changed. Moreover, while the mark M3 is moving, it is also conceivable that the dotted line / solid line display of the traffic congestion sections 91 and 92 changes or the section length expands and contracts.

  Further, although the congestion information is displayed based on the real-time road traffic information in the examples of FIGS. 9 and 10, the congestion information may be displayed based on the congestion prediction information.

  In addition, the difference between the congestion level and the congestion section (traffic congestion length) can be changed by changing the display mode such as display color, line thickness, etc., or changing the content of supplementary messages, in addition to dotted line / solid line display. You may distinguish. Further, the congestion degree is not limited to two stages, and may be distinguished in more stages.

  Further, the degree of congestion and the congestion section may be displayed on the time control bar screen 41b. In this case, a congestion section bar indicating the congestion section may be displayed along the time axis 51 from the time of entering the congestion section to the time of leaving the congestion section. In addition, the display mode of the congestion section bar is also variable (in accordance with the position of the mark M3) in accordance with the congestion information displayed on the map screen.

  In the case of facility information as well, in the examples of FIGS. 9 and 10, the present invention can be applied to a configuration in which the range of the peripheral information of the vehicle is narrowed or the map screen scrolls along with the movement of the vehicle estimated position P3. Is the same as

  As described above, according to the second embodiment, in order to display the position of the vehicle at the time designated by the user and the peripheral information thereof on the map, the user “the vehicle reaches an arbitrary facility on the guidance route. At the time, it can be known whether or not the facility is open. In addition, since it is possible to specify the time by operating the time control bar screen 41b, peripheral information of the vehicle estimated position P3 can be confirmed with a fine resolution (continuously).

  In the above embodiment, display data to be displayed on the touch panel 16 as peripheral information is acquired, but audio data to be output from the speaker 17 may be acquired. That is, the peripheral information may be voice-guided in accordance with the operation of the mark M3. For example, voice guidance such as "a xxx store has been opened at a designated time" or "a traffic jam of km km from xxx to xx has occurred at a designated time" may be considered.

  Further, although the peripheral information is acquired from the information providing server 30 in the above embodiment, the peripheral information may be acquired from a database (not shown) stored in the in-vehicle apparatus 1.

  In the above embodiment, the mark M3 is moved in the future direction, but may be moved in the past direction. Further, by aligning the mark M3 with the position of the mark M0, the mark M1 or the mark M2, peripheral information of the departure point, the current position (vehicle current position P1) or the destination can also be displayed.

  Moreover, in said embodiment, although description in the case of displaying weather information as periphery information was abbreviate | omitted, also about weather information, the display changes with the movement of the mark M3. As a display method of weather information, it is conceivable to superimpose and display a colored filter (fine: red, cloudy: gray, rain: blue, etc.) indicating each weather and its range on the forecasted area on the map. Also, the past weather information reflects the actual weather, and the future weather information reflects the weather forecast (weather forecast information acquired from the information providing server 30).

  As mentioned above, although two embodiment was shown, it is possible to provide each component of the vehicle-mounted apparatus 1 shown to each embodiment as a program. It is also possible to store the program in various recording media (CD-ROM, flash memory, etc.) and provide it. That is, a program for causing a computer to function as each component of the in-vehicle apparatus 1 and a recording medium recording the same are also included in the scope of the present invention.

  Moreover, although the case where the display apparatus of this invention was applied to the vehicle-mounted apparatus 1 was illustrated in said embodiment, you may apply to other information terminals, such as a smart phone and a mobile telephone. In addition, the present invention may be applied to the case of guiding a moving object such as a person instead of guiding the vehicle. In addition, changes can be made as appropriate without departing from the scope of the present invention.
