  The route guide unit 14 guides the route searched by the search unit 13 to the user (passenger) of the host vehicle. For example, the route guide unit 14 displays the position of the host vehicle in the center of the screen on the map display screen (on the map), and displays the route searched by the search unit 13 in a predetermined color. 15 is displayed on the screen.

  The display control unit 15 displays information for route guidance on the screen in accordance with instructions from the route guidance unit 14.

<Processing>
Next, an example of route guidance processing of the information processing apparatus 10 will be described with reference to FIGS. 3 to 6B. FIG. 3 is a flowchart illustrating an example of route guidance processing of the information processing apparatus 10 according to the embodiment. 4A and 4B are diagrams illustrating an example of a display screen that displays a difference in route. 5A and 5B are diagrams illustrating an example of a display screen that displays an enlarged portion of a path difference. 6A and 6B are diagrams for explaining an example of a display screen after one of the enlarged differences is selected.

  In step S <b> 1, the reception unit 12 receives an operation for setting a destination or the like from the user when starting route guidance (an example of “first time point”). Subsequently, the route guidance unit 14 causes the search unit 13 to calculate a plurality of route candidates from the current location to the destination, and causes the display control unit 15 to display the calculated plurality of route candidates on the screen (step S2). . Here, the search unit 13 has a plurality of different search conditions such as a recommended route, a toll road priority route, a general road priority route, and a distance priority route based on the current road conditions. Route candidates may be calculated.

  Subsequently, the accepting unit 12 accepts an operation of selecting one route (an example of “first route”) from a plurality of route candidates (step S3).

  Subsequently, the route guidance unit 14 performs route guidance according to the selected route (step S4). Here, for example, the route guidance unit 14 displays a route to the destination on a map screen with the position of the host vehicle as the center of the screen, and voice for guiding operations such as a right turn and a left turn on the route. Is output.

  Subsequently, the route guidance unit 14 determines whether or not to finish the route guidance (step S5). Here, for example, the route guidance unit 14 may determine to finish the route guidance when the current position of the host vehicle falls within a predetermined range from the set destination.

  When the route guidance is not terminated (NO in step S5), the route guidance unit 14 determines a new route (“second route”) from the current location to the destination at a predetermined timing (“second time point”). One example.) Is caused to search by the search unit 13 (step S6). Here, the route guide unit 14 causes the search unit 13 to search for a route having a short estimated arrival time at the destination based on the current road conditions at a predetermined interval (for example, every 5 minutes), for example. Also good. In addition, the route guidance unit 14 routes the route to the destination when information on road conditions such as traffic jams, accidents, and traffic regulations is updated by a VICS (registered trademark) (Vehicle Information and Communication System) or a server. May be searched by the search unit 13.

  Subsequently, the route guide unit 14 determines whether or not to propose a new route (step S7). Here, the route guidance unit 14 determines that the difference between the estimated arrival time to the destination on the original route (original route, old route) and the estimated arrival time to the destination on the new route (new route) is If it is equal to or greater than a predetermined threshold (for example, 10 minutes), it may be determined that a new route is proposed. In addition, for example, when there is a traffic jam due to an accident, etc., or when the speed that the vehicle has traveled is different from the originally expected speed, there is a route that cannot be accessed due to time zone restrictions on the original route, etc. Depending on the situation, the difference may be equal to or greater than a predetermined threshold.

  When a new route is not proposed (NO in step S7), the process proceeds to step S4. On the other hand, when a new route is proposed (YES in step S7), the display control unit 15 displays the original route for which route guidance is being performed and the new route on the screen (step S8).

  In the example of FIG. 4A, the display control unit 15 displays an area 400 for displaying a map, an icon 401 indicating the current host vehicle, an icon 402 indicating a waypoint, an icon 403 indicating a destination, a display area 404, and a display area. 405, an “original route” button 406, a “new route” button 407, a line 408 indicating the original route, a line 409 indicating the new route, and the like are displayed. In the example of FIG. 4A, the display control unit 15 displays the line 408 indicating the original route in blue and the line 409 indicating the new route in green, but the portion where the line 408 and the line 409 overlap is indicated by a line Only 408 is displayed. The transit point indicated by the icon 402 is a transit point set in advance in the process of step S1 and is a transit point between the current location and the destination.

  In the display area 404, the display control unit 15 displays the travel distance 404A, the required time 404B, and the fee 404C in the original route, the travel distance 404D, the required time 404E, the fee 404F, and the like in the new route. Yes. Further, the display control unit 15 displays a message 404G indicating that the original route is guided when the host vehicle travels 500 m in the display area 404. While the screen of FIG. 4A is being displayed, the route guidance unit 14 performs an operation of enlarging and displaying the difference portion of the route, the operation of the “original route” button 406, the “new route” button 407, etc. When the host vehicle travels a predetermined distance (for example, 500 m), a route included in the original route may be selected in the one difference portion.

  In the display area 405, the display control unit 15 displays a “wide area” button 405A, a scale bar value 405B, a scale bar 405C, and a “details” button 405D. In the example of FIG. 4A, in the area 400 for displaying the map displayed on the screen, the display control unit 15 sets the scale of the map, the length of the scale bar 405C, and the scale bar value 405B. It is shown that it is such a scale (an example of “first scale”). When the “wide area” button 405 </ b> A is pressed, the display control unit 15 displays a wider map with a reduced scale. When the “details” button 405D is pressed, the display control unit 15 displays a more detailed map that is one scale larger and partially enlarged.

  The route 412 and the route 422 are different portions of the route included in the original route from the route included in the new route. The route 413 and the route 433 are different portions of the route included in the new route from the route included in the original route. A figure 411 is a figure of a square frame surrounding the path 412 and the path 413. A figure 421 is a figure of a square frame surrounding the path 422 and the path 423. In the example of FIG. 4A, the display control unit 15 displays the difference between the original route and the new route with emphasis (an example of “different display mode”) using the graphic 411 or the like. The display control unit 15 may set the colors of the graphic 411 and the graphic 421 to a conspicuous color such as red.

  When the “original route” button 406 is pressed on the display screen of FIG. 4A, the route guide unit 14 guides the original route including the route 412 and the route 422. When the “new route” button 407 is pressed on the display screen of FIG. 4A, the route guide unit 14 guides a new route including the route 413 and the route 433.

  In addition, the display control part 15 may display the said part in a special display mode, when a living road is contained in the part of the difference in a new path | route. The living roads may include, for example, a road having one lane, a relatively narrow road having a road width equal to or less than a predetermined threshold, a municipal road, and a private road. The display control unit 15 may determine whether each link is a living road in the map data 111 based on attribute information of each link.

  In addition, as the special display mode, for example, a message or icon indicating that a living road is included is added to the part and displayed, and the part is different from the line color indicating a new route such as yellow. The color may be displayed, and the nucleus surrounding the portion may be displayed in yellow or the like. In this case, in the example of FIG. 4B, the display control unit 15 is a display screen similar to the display screen of FIG. 4A. However, since the route 433 is a route including a link that is a living road, the attention mark icon 433A, In addition, a message 433 </ b> B that “passes the living road” is added to the route 433 and displayed.

  In addition, in the example of FIG. 4B, the display control unit 15 displays an icon 411A (an example of “first code”) indicating a code for selecting by voice operation or operation on a list, and an icon 421B ( An example of “second code”) is added to each part of the difference and displayed. The selection code is not limited to numerals but may be alphabets, hiragana, or the like. In the example of FIG. 4B, the display control unit 15 displays a list of buttons 431A and 431B for selecting each part of the difference in the region 431. The buttons 431A and 431B are labeled with selection codes included in the icons 411A and 421B, respectively. By displaying a list of buttons for selecting each part of the difference, for example, even when the number of the difference parts is large and when the distance between the difference parts is short, the process of step S9 described later is performed. This makes it easier to select the part of the difference to be enlarged. Further, by adding a selection code to each portion of the difference and displaying it, the code can be used as a voice command during driving, for example. In this case, when the receiving unit 12 receives the sound of the code for selection, the receiving unit 12 recognizes the code for selection by recognizing the sound. Then, the display control unit 15 enlarges and displays the portion of the difference to which the selection code is attached in the process of step S9 described later.

<Variation of highlighting>
In the process of step S8, the display control unit 15 instead of or displays a frame that surrounds the difference between the original route and the new route, such as the graphic 411 and the graphic 421 in FIG. 4A. In addition, the difference may be displayed with emphasis by the following display mode.

  For example, the display control unit 15 may cause the graphic 411 and the graphic 421 in FIG. 4A, which are frames surrounding the differences between the original route and the new route, to blink.

  Further, the display control unit 15 may blink and display at least one of the differences between the original route and the new route, for example. In this case, when the difference portion in the new route is blinked, in the example of FIG. 4A, the display control unit 15 is a route that is different from the route included in the original route among the routes included in the new route. 413 and the path 433 are blinked. Thereby, the difference part in a new path | route can be made more conspicuous. Further, in the case of blinking the difference portion in the original route, the display control unit 15 in the example of FIG. 4A, the route 412 that is different from the route included in the new route among the routes included in the original route. , And the path 422 is blinked. Thereby, the difference part in the original path | route can be made more conspicuous.

  Further, for example, the display control unit 15 may display an object such as a finger mark or a caution mark added to at least one of the differences between the original route and the new route.

  The display control unit 15 may combine the above-described highlighting. In this case, for example, the display control unit 15 may cause the difference portion in the new route to blink, and add an object such as a caution mark to the difference portion in the original route. This makes it easier to understand that it takes time to pass through the route where the traffic jam occurred in the original route and that a new route is proposed instead of the route where the traffic jam occurred. be able to.

  Subsequently, the display control unit 15 enlarges and displays the route of the difference portion in the original route and the route of the difference portion in the new route (step S9). Here, on the display screen in FIG. 4A, when any one of the area surrounded by the graphic 411, the path 412 and the path 413 is pressed, the display control unit 15 displays the display screen in FIG. 5A. Further, in the case of the display screen of FIG. 4B, the display control unit 15 also displays the display screen of FIG. 5A when the button 431A is pressed and when the selection code included in the icon 411A is recognized by voice. The display control unit 15 also displays the difference portion when the distance between the original route and the branch position of the new route in the difference portion and the host vehicle is equal to or less than a predetermined threshold (for example, 5 km). It may be enlarged and displayed automatically.

  In the example of FIG. 5A, the display control unit 15 has an area 511 in front of the area 400 in association with the difference between the path 412 and the path 413 among the difference between the original path and the new path. It is displayed. In the example of FIG. 5A, the display control unit 15 slides (moves) the center position of the map displayed in the area 400 of FIG. 4A in the upper right direction and displays it in the area 400 of FIG. 5A. This is to prevent the difference portion in the region 400 of FIG. 5A from overlapping the region 511. Thereby, on the one display screen, the part of the difference in the original map and the part of the difference in the enlarged map can be displayed simultaneously.

  In the example of FIG. 5A, the display control unit 15 displays the difference portion in the area 511 in an enlarged manner than the difference portion in the area 400 of the original map screen. In the example of FIG. 5A, the display control unit 15 displays the map at a scale where the length of the scale bar 405C is “2.0 km” which is the value 405B of the scale bar in the region 400, whereas In 511, the scale bar 512C has the scale bar value 512B of “1.0 km” (an example of “second scale”), and a more detailed map is enlarged and displayed. .

  A “wide area” button 512A and a “details” button 512D in the display area 512 are the same as the “wide area” button 405A and the “details” button 405D in the display area 405, respectively, but the map displayed in the area 511 is displayed. It is a button for changing the scale.

  When one of the area surrounded by the graphic 421, the path 422, and the path 423 is pressed on the display screen of FIG. 4A, the display control unit 15 displays the display screen of FIG. 5B. Note that the display control unit 15 also displays the display screen of FIG. 5B when the button 431B is pressed on the display screen of FIG. 4B and when the selection code included in the icon 421A is voice-recognized.

  In the example of FIG. 5B, the display control unit 15 associates the area 521 with a difference between the path 422 and the path 423 out of the difference between the original path and the new path on the front of the area 400. It is displayed. In the example of FIG. 5B, the display control unit 15 slides the map displayed in the area 400 of FIG. 5B to the right of the map displayed in the area 400 of FIG. 4A. This is to prevent the difference portion in the region 400 of FIG. 5B from overlapping the region 521.

  In the example of FIG. 5B, the display control unit 15 displays the difference portion in the area 521 in an enlarged manner than the difference portion in the area 400 of the original map screen. In the example of FIG. 5B, the display control unit 15 displays an enlarged map at a more detailed scale in the area 521 at a scale where the length of the scale bar 512C is “500 m” which is the value 512B of the scale bar. ing.

  The display control unit 15 makes the position and size of the area 511 on the screen in FIG. 5A the same as the position and size on the screen of the area 521 in FIG. 5B. In this way, it is possible to make it easier to see by fixing the enlarged display area regardless of the actual distance of the difference portion.

  Subsequently, the route guide unit 14 selects one of the difference portion and the portion included in the original route and the portion included in the new route, and the route to the destination including the selected route portion. Is set (step S10), and the process proceeds to step S4. Here, the route guidance unit 14 determines whether the difference portion included in the new route or the difference portion included in the old route is a user operation with respect to the portion when enlarged display is performed in the process of step S9. Or in response to a predetermined condition.

  In this case, for example, when the “original route” button 406 is pressed on the display screen of FIG. 5A, the route guide unit 14 selects the route 412 included in the original route, and the display control unit 15 selects the route 412 of FIG. Display the display screen. In the display screen of FIG. 6A, the route guide unit 14 deletes the display of the graphic 411 and the route 413 in the display screen of FIG. 4A. When the “new route” button 407 is pressed on the display screen of FIG. 5A, the route guide unit 14 selects the route 413 included in the new route, and displays the display screen of FIG. 6B. In the display screen of FIG. 6B, the route guide unit 14 deletes the display of the graphic 411 and the route 412 on the display screen of FIG. 4A and displays the route 413 as the original route. Therefore, when the “original route” button 406 is pressed on the display screen of FIG. 6B, the route guide unit 14 selects the original route in the portion in the figure 421 while selecting the already selected route 413. The included path 422 is selected. In addition, when the “new route” button 407 is pressed on the display screen of FIG. 6B, the route guide unit 14 selects a new route in the portion in the figure 421 while selecting the route 413 that has already been selected. The included route 423 is selected.

  Then, when the route guidance unit 14 receives a route selection operation in all differences, the route guidance unit 14 proceeds to the process of step S4, and resumes route guidance on the selected route.

  Further, as shown in FIG. 5A and the like, the route guide unit 14 enlarges and displays the one difference portion, and then the host vehicle moves the predetermined distance without performing an operation of selecting the route in the one difference portion. When traveling (for example, 500 m), a route included in a new route may be selected in the part of the one difference. This is because it is considered that the user understood the new route in the difference portion because the user drove and displayed the difference portion to drive the vehicle. In this case, the display control unit 15 may display a message to that effect. The display control unit 15 displays, for example, a display area 404 or an area in the vicinity of the area 511 that enlarges and displays the part of the one difference. A message such as “.” May be displayed. Further, as shown in FIG. 5A and the like, the route guide unit 14 enlarges and displays one difference portion, and then selects a route in the one difference portion for a predetermined time (for example, one minute) or longer. Even when there is no operation, a route included in a new route may be selected in the part of the one difference. Thereby, the user can concentrate on driving | running | working, without operating the button for selection, after carrying out enlarged display and confirming visually. In this case, the display control unit 15 may display a message to that effect. The display control unit 15 displays, for example, the display area 404 or an area in the vicinity of the area 511 where the one difference portion is enlarged and displayed, “in 1 minute, a new route is guided for the enlarged display portion. A message such as “.” May be displayed.

In addition, the route guide unit 14 displays the one difference portion when the vehicle travels a predetermined distance (for example, 500 m) without displaying the enlarged one difference portion after the one difference portion is displayed. In the difference portion, a route included in the original route may be selected. In this case, for example, after the display screen shown in FIG. 4A or the like, the route guidance unit 14 enlarges and displays the difference portion between the route 422 included in the original route and the route 423 included in the new route. When the vehicle travels without displaying the screen, the route 422 included in the original route is selected in the difference portion. This is because it is considered that the user does not understand the new route in the difference portion because the user has driven the vehicle without enlarging the difference portion. In addition, after the one difference portion is displayed, the route guide unit 14 displays the one difference portion in the one difference portion for a predetermined time (for example, one minute) or longer without expanding and displaying the one difference portion. Even when there is no operation for selecting a route, a route included in the original route may be selected in the part of the one difference. Thereby, when the user is not interested in a new route, the user can concentrate by driving without operating a button for selection.
On the other hand, when the route guidance is finished (YES in step S5), the process is finished.

<Modification>
In the above-described example, when a new route is searched according to a change in road conditions, a case in which a portion different from the original route is displayed in an enlarged manner has been described. It can also be applied to the case of selecting one route from a plurality of routes in step S3. In this case, for example, the route guide unit 14 enlarges and displays a portion of one or more differences between the recommended route and the distance priority route on the display control unit 15, and sets the route to the destination including the selected portion. To do. Thus, for example, when there are multiple differences between the recommended route and the distance-priority route, the route is a combination of the difference portion included in the recommended route and the difference portion included in the distance-priority route. Can be set.

  As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to such specific embodiment, In the range of the summary of this invention described in the claim, various deformation | transformation・ Change is possible.
