  Exemplary embodiments of a point guide device, a point guide method, a point guide program, and a recording medium according to the present invention will be explained below in detail with reference to the accompanying drawings.

(Embodiment)
(Functional configuration of point guidance device)
A functional configuration of the point guidance apparatus 100 according to the embodiment of the present invention will be described. FIG. 1 is a block diagram illustrating an example of a functional configuration of the point guide device 100 according to the embodiment. In FIG. 1, the point guidance apparatus 100 includes a guidance unit 110, a control unit 111, an output unit 112, a display unit 113, a voice output unit 114, an input unit 120, and a setting unit 130.

  The guide part 110 performs the 1st guidance about a guidance point. The input unit 120 receives a guidance request from the user after the first guidance. When the guidance unit 110 receives a guidance request from the user through the input unit 120, the guidance unit 110 performs second guidance on the guidance point with contents different from the first guidance.

  The guidance point is a point where guidance is set in advance from the initial setting, road shape, and the like, such as an intersection, a branch point, a junction point, and the like. For example, when the vehicle approaches the guidance point, the first guidance provides details such as notifying the lane to be traveled and landmarks that serve as landmarks, and displaying the display screen in an enlarged manner or by voice notification. It is a guide.

  The second guidance only needs to be different from the first guidance. For example, a display screen with a different viewpoint from the first guidance is displayed, a map screen more detailed than the first guidance, What is necessary is just to give a voice notification different from the guidance.

  Specifically, the guide unit 110 includes a control unit 111 and an output unit 112. The control unit 111 performs control for receiving an input from the user when the first guidance is performed. Specifically, for example, the user is notified of whether or not the second guidance is performed on a display screen or the like. The output unit 112 outputs guidance contents. The output format by the output unit 112 may be voice, display, or a combination of both. The input format by the input unit 120 may be an operation input or a voice input.

  Further, in the present embodiment, when the guidance unit 110 receives a guidance request from the user through the input unit 120, the guidance unit 110 performs the second guidance using the feature of the guidance point that is not used in the first guidance. Also good. The guidance point is a point where guidance on the route is performed, such as a branch point or an intersection that requires a right or left turn. Note that the timing at which the guidance is started is specifically when it is located within a predetermined range from the guidance point.

  Characteristic objects are landmarks around the guide point, and specifically include pedestrian bridges, overpasses, railroad crossings, signboards, signs, guardrails, etc., but typically, traffic lights at the guide points, Examples include roads located in front of the guide points and facilities around the guide points. If a specific example is given, if the guidance part 110 is performing the 1st guidance using the traffic light, in the 2nd guidance, it will guide using the characteristics other than the traffic light. In this configuration, the feature is different between the first guide and the second guide so that the user can recognize the feature that could not be recognized by the first guide by the second guide. It is.

  In the present embodiment, the input unit 120 may receive an input of a guidance type together with a guidance request from the user. In this case, when the guidance unit 110 receives a guidance request and type from the user via the input unit 120, the guidance unit 110 performs the second guidance using the feature of the guidance point corresponding to the type. The type of guidance specifically refers to which features are used for guidance. Signal guidance using traffic lights, number of front roads using front roads, and facility guidance using facilities. It is desirable that at least one of them is included.

  If there is no feature corresponding to the user's request at the guidance point, the fact may be notified, or input for a feature that does not exist at the guidance point may not be received in advance. Also good. In this configuration, the second guidance is performed using the feature desired by the user.

  In the present embodiment, the setting unit 130 is an arbitrary component. The setting unit 130 sets the priority order of guidance types. In this case, when the guidance unit 110 receives a guidance request from the user via the input unit 120, the guidance unit 110 provides the second guidance using the feature of the guidance point corresponding to the next rank type of the first guidance type. Do it.

  In the setting unit 130, a higher priority may be set for a feature with good visibility or a feature that stands out. Note that the setting of the priority order to the setting unit 130 may be set in advance at the time of manufacturing, may be set to be appropriately changeable based on an input from the user, and the number of requests from the user may be set. It may be set in descending order. In this configuration, a feature effective for the user is used for guidance according to the priority order, and allows the user to quickly recognize the feature and the guidance route.

  Moreover, in this Embodiment, the guidance part 110 may display a guidance image using the display part 113 as the output part 112, and may guide a guidance point. Specifically, the display unit 113 is a display. In this case, when the guidance unit 110 receives a guidance request from the user through the input unit 120, the guidance unit 110 adds an icon indicating a feature of a guidance point not used for the first guidance to the guidance image of the first guidance. The added guidance image may be displayed on the display unit 113 to perform the second guidance. Specifically, the icon indicates a feature such as a traffic light with a symbol, a picture, or a figure.

  To give a specific example, when the first guidance with an icon indicating a traffic light is being performed, the guidance unit 110 indicates a nearby facility in addition to the icon indicating the traffic light when receiving a guidance request. Add an icon and give the second guide. This configuration makes it possible to sequentially add information to the user and present information to the user.

  In the present embodiment, when the guide unit 110 displays a guide image on the display unit 113 to guide a guide point, when the input unit 120 receives a guide request from the user, the guide unit 110 The icon indicating the feature of the guide point used for the first guidance is deleted from the guide image, and the icon indicating the feature of the guide point not used for the first guidance is added to the guide image. May be displayed on the display unit 113 to provide the second guidance.

  To give a specific example, the guide unit 110 deletes the icon indicating the traffic light when the first guidance with the icon indicating the traffic light is being performed and receives the guidance request, Only the icon to show is added and 2nd guidance is performed. This configuration makes it possible to sequentially present only information different from the first guidance to the user.

  Moreover, in this Embodiment, the guidance part 110 may output a guidance audio | voice using the audio | voice output part 114 as the output part 112, and may perform guidance of a guidance point. Specifically, the audio output unit 114 is a speaker. In this case, when the guidance unit 110 receives a guidance request from the user through the input unit 120, the guidance unit 110 outputs guidance voices that guide the features at the guidance point not used for the first guidance during the first guidance. The second guidance may be performed by adding the guidance voice to the guidance voice and outputting the added guidance voice from the voice output unit 114.

  To give a specific example, when the first guidance for outputting the guidance voice using the traffic light is being performed, the guidance unit 110 receives the guidance request when the guidance request is received, A guidance voice using the facility is added to provide the second guidance. This configuration makes it possible to sequentially add information to the user and present information to the user.

  In the present embodiment, when the guidance unit 110 outputs guidance voice from the voice output unit 114 to guide the guidance point, the guidance unit 110 receives the guidance request from the user via the input unit 120 and receives the first guidance. Alternatively, the second guidance may be performed by outputting only a guidance voice for guiding a feature at a guidance point that is not used for the navigation.

  As a specific example, when the first guidance for outputting a guidance voice using a traffic light is performed, the guidance unit 110 does not use the guidance voice using a traffic light when receiving a guidance request. The second guidance is provided by guidance voice using only surrounding facilities. This configuration makes it possible to sequentially present only information different from the first guidance to the user.

  Moreover, in this Embodiment, the guidance part 110 should just perform 1st guidance, when a mobile body approaches within the predetermined range from a guidance point. In this case, the input unit 120 may receive a guidance request from the user from the start of the first guidance until the moving body passes the guidance point. Note that the point guide device 100 may be built in a portable device that can be carried by the user, in addition to the device installed in a vehicle or the like. That is, the moving body referred to here includes the user itself in addition to the vehicle.

  Moreover, in this Embodiment, the input part 120 is good also as being able to receive a guidance request | requirement from a user in multiple times from the start of 1st guidance until a mobile body passes a guidance point. In this case, every time the guidance unit 110 receives a guidance request from the user via the input unit 120, the guidance unit 110 may perform guidance on the guidance point with contents different from the guidance so far. Specifically, the guidance unit 110 sequentially provides guidance as third guidance, fourth guidance, fifth guidance,... According to the number of times a guidance request is received from the user by the input unit 120. .

  In the configuration in which the priority is set in the setting unit 130, when there is no feature corresponding to the next rank type, the guide unit 110 further selects a feature corresponding to the next rank type. Use it for guidance. This configuration makes it possible to change the guidance content until the user can recognize the guidance route.

(Point guide device search processing procedure)
Next, the search processing procedure of the point guide device 100 will be described with reference to FIG. FIG. 2 is a flowchart illustrating an example of a search processing procedure of the point guide device 100 according to the present embodiment.

  In the flowchart of FIG. 2, it is assumed that the point guide device 100 performs route guidance to the destination. The point guidance apparatus 100 first determines whether or not the mobile object is located at the guidance point (step S201). Note that the determination in step S201 is specifically a determination of whether or not the mobile object is located within a predetermined range from the guidance point. In step S201, it is in a standby state until the moving body is located at the guidance point (step S201: No loop). When the moving body is located at the guidance point (step S201: Yes), the first guidance is performed (step S202). ).

  Then, it is determined whether a guidance request has been accepted (step S203). In step S203, when a guidance request is received (step S203: Yes), second guidance is performed (step S204). And it is judged whether it passed the guidance point (step S205).

  In step S205, when it is determined that the vehicle has not passed the guidance point (step S205: No), the guidance is continued (step S206), and the process proceeds to step S203. On the other hand, when the guidance request is not accepted in step S203 (step S203: No), the process proceeds to step S205. If it is determined in step S205 that the guide point has been passed (step S205: Yes), the series of processing ends.

  In the above description, for the sake of convenience, the two guides, the first guide and the second guide, are described. However, in step S203, the second guide is provided when the guide request is received. There is. In this case, the guidance in step S204 is the third guidance. In addition, when the third guidance is performed and the guidance request is accepted, the guidance in step S204 becomes the fourth guidance. Accordingly, the “second guidance” in step S204 is, in other words, “a different guidance”.

  As described above, the point guidance device 100 according to the present embodiment performs the second guidance with the content different from the first guidance when the guidance request is received after the first guidance. . Therefore, for the user, even if the route to be guided cannot be recognized by the first guidance, the route to be guided can be recognized by the second guidance, and the user can reach the destination without hesitation. Can be reached. Thus, the point guidance apparatus 100 concerning this Embodiment can perform the guidance containing the information which a user desires according to the request | requirement from a user.

  Specifically, when there is a shield or the like that reduces the visibility of the feature in front of the feature used for the first guidance, or when the feature is difficult to see due to direct sunlight, etc. In a situation where an object cannot be recognized, if the second guidance is performed using a feature different from the feature used for the first guidance, the user can easily recognize the feature. At the same time, the route to be guided can be recognized.

  In step S601, the vehicle is on standby until the vehicle is positioned at the guidance point (step S601: No loop). When the vehicle is positioned at the guidance point (step S601: Yes), the first guidance is performed (step S602). The first guidance is, for example, an enlarged display of the display screen.

  And it is judged whether it is a guidance point with a feature (step S603). If it is determined in step S603 that the guide point has a characteristic object (step S603: Yes), a notification for accepting a guide request is issued (step S604), and the series of processing ends.

  Specifically, in step S604, for example, a message such as “Do you want to display a landmark?” Or voice output is displayed. In step S604, a notification for accepting the type of guidance may be given. The type of guidance is which feature is used for guidance, and is traffic light guidance, front road number guidance, and facility guidance. Note that a display screen that accepts an input of a guidance type will be described later with reference to FIGS.

  On the other hand, if it is determined in step S603 that it is not a guide point with a feature (step S603: No), a series of processing ends. The processing after the notification of accepting the guidance request in step S604 will be described below with reference to FIG.

(Example of point guidance processing performed by the navigation device)
Next, an example of the spot guidance process performed by the navigation device 300 according to the present embodiment will be described with reference to FIG. FIG. 7 is a flowchart illustrating an example of the spot guidance process performed by the navigation device 300 according to the present embodiment. In the flowchart shown in FIG. 7, processing in the case of using a feature according to the priority order will be described.

  In FIG. 7, the navigation apparatus 300 is in a state after a notification for accepting a guidance request is made at a guidance point, and determines whether or not a guidance request has been accepted (step S701). The input method for accepting the guidance request in step S701 is operation input or voice input. If it is determined in step S701 that a guidance request has been received (step S701: Yes), a high priority feature is extracted (step S702). A feature with a high priority is a traffic light if the setting information 500 shown in FIG. 5 is used.

  Then, an icon corresponding to the extracted feature is displayed (step S703). In step S703, a message such as “Do you want to display another landmark?” Is displayed or output as a notification that the guidance request can be accepted together with the display of the icon. Moreover, what is necessary is just to output the guidance sound using a traffic light, when performing guidance by an audio | voice in step S703.

  Then, it is further determined whether a guidance request has been received (step S704). The acceptance input method in step S704 may be an operation input or a voice input as in step S701. If it is determined in step S704 that a further guidance request has been received (step S704: Yes), the next highest priority feature is extracted (step S705). The next highest priority feature is a facility when the setting information 500 shown in FIG. 5 is used.

  Then, an icon corresponding to the extracted feature is added and displayed (step S706). That is, in step S706, the signal icon and the facility icon are displayed simultaneously. Further, in step S706, not only adding and displaying an icon, but it is also possible to delete the previously displayed icon and display only the icon extracted this time. That is, only the facility icon may be displayed without displaying the signal icon.

  Further, in the case where guidance by voice is performed in step S706, guidance voice using a traffic light and a facility may be output. After the process of step S706, the process proceeds to step S704.

  On the other hand, when the guidance request is not accepted in step S701 (step S701: No), it is determined whether or not the guidance point has been passed (step S707). In step S707, until it passes through the guide point (step S707: No), the process proceeds to step S701, and when it is determined that the guide point is passed (step S707: Yes), the series of processing ends.

  In step S704, when a guidance request is not accepted (step S704: No), it is determined whether or not a guidance point has been passed (step S708). In step S708, until it passes through the guidance point (step S708: No), the process proceeds to step S703, and when it is determined that the guidance point is passed (step S708: Yes), the series of processing ends.

  According to the processing described above, guidance according to the priority order is performed for the amount of guidance request received until the guidance point is passed. Specifically, guidance is provided by adding icons. Therefore, the user can make a guidance request until the feature is recognized, and the user can follow the guidance route without getting lost by using the recognized feature as a landmark.

(Another example of point guidance processing performed by the navigation device)
Next, another example of the spot guidance process performed by the navigation device 300 according to the present embodiment will be described with reference to FIG. FIG. 8 is a flowchart illustrating another example of the spot guidance process performed by the navigation device 300 according to the present embodiment. In the flowchart shown in FIG. 8, processing in the case of using a feature according to the type of guidance requested by the user will be described.

  In FIG. 8, the navigation apparatus 300 is in a state where a notification for accepting an input of a guidance type has been made at a guidance point, and determines whether or not an input of a guidance type has been accepted (step S801). The details of the display screen that accepts the input of the guidance type will be described later with reference to FIGS.

  The types of guidance are, for example, traffic light guidance, front road number guidance, and facility guidance. The input method for accepting the guidance type in step S801 is operation input or voice input. If it is determined in step S801 that an input of a guidance type has been received (step S801: Yes), the received type of feature is extracted (step S802). Specifically, when the traffic signal guidance is received, the traffic signal at the guidance point is extracted.

  Then, an icon corresponding to the extracted type of feature is displayed (step S803). In step S803, an icon is displayed and a notification that can accept an input of a guidance type is given. Further, in the case where guidance by voice is performed in step S803, guidance voice using a traffic light may be output.

  Then, it is further determined whether or not an input of guidance type has been accepted (step S804). The input method of acceptance in step S804 may be operation input or voice input as in step S801. If it is determined in step S804 that an input of a guidance type has been received (step S804: Yes), the received type of feature is extracted (step S805). Specifically, when facility guidance is received, facilities around the guidance point are extracted.

  Then, an icon corresponding to the extracted type of feature is added and displayed (step S806). That is, in step S806, a traffic light icon and a facility icon are displayed simultaneously. Further, in step S806, not only adding and displaying an icon, but it is also possible to delete the previously displayed icon and display only the icon extracted this time. That is, only the facility icon may be displayed without displaying the signal icon.

  Further, in the case where guidance by voice is performed in step S806, guidance voice using a traffic light and a facility may be output. After the process of step S806, the process proceeds to step S804.

  On the other hand, if no guidance type input is accepted in step S801 (step S801: No), it is determined whether or not the guidance point has been passed (step S807). In step S807, the process proceeds to step S801 until it passes through the guide point (step S807: No), and if it is determined that the guide point has been passed (step S807: Yes), a series of processing ends.

  If no guidance type input is accepted in step S804 (step S804: No), it is determined whether or not the guidance point has been passed (step S808). In step S808, the process proceeds to step S803 until it passes through the guide point (step S808: No). When it is determined that the guide point has been passed (step S808: Yes), the series of processing ends.

  According to the above-described processing, the guidance corresponding to the input of the guidance type is performed until the guidance point is passed. Specifically, guidance is provided by adding icons. Therefore, the user can make a request for the type of guidance until the feature is recognized, and can use the recognized feature as a mark to follow the guidance route without getting lost.

In FIG. 1, the point guidance apparatus 100 includes a guidance unit 110, a control unit 111, an output unit 112, a display unit 113, a voice output unit 114, an input unit 120, and a setting unit 130.

  The guide part 110 performs the 1st guidance about a guidance point. The input unit 120 receives a guidance request from the user after the first guidance. When the guidance unit 110 receives a guidance request from the user through the input unit 120, the guidance unit 110 performs second guidance on the guidance point with contents different from the first guidance.

  The guidance point is a point where guidance is set in advance from the initial setting, road shape, and the like, such as an intersection, a branch point, a junction point, and the like. For example, when the vehicle approaches the guidance point, the first guidance provides details such as notifying the lane to be traveled and landmarks that serve as landmarks, and displaying the display screen in an enlarged manner or by voice notification. It is a guide.

  The second guidance only needs to be different from the first guidance. For example, a display screen with a different viewpoint from the first guidance is displayed, a map screen more detailed than the first guidance, What is necessary is just to give a voice notification different from the guidance.

  Specifically, the guide unit 110 includes a control unit 111 and an output unit 112. The control unit 111 performs control for receiving an input from the user when the first guidance is performed. Specifically, for example, the user is notified of whether or not the second guidance is performed on a display screen or the like. The output unit 112 outputs guidance contents. The output format by the output unit 112 may be voice, display, or a combination of both. The input format by the input unit 120 may be an operation input or a voice input.

  Further, in the present embodiment, when the guidance unit 110 receives a guidance request from the user through the input unit 120, the guidance unit 110 performs the second guidance using the feature of the guidance point that is not used in the first guidance. Also good. The guidance point is a point where guidance on the route is performed, such as a branch point or an intersection that requires a right or left turn. Note that the timing at which the guidance is started is specifically when it is located within a predetermined range from the guidance point.

  Characteristic objects are landmarks around the guide point, and specifically include pedestrian bridges, overpasses, railroad crossings, signboards, signs, guardrails, etc., but typically, traffic lights at the guide points, Examples include roads located in front of the guide points and facilities around the guide points. If a specific example is given, if the guidance part 110 is performing the 1st guidance using the traffic light, in the 2nd guidance, it will guide using the characteristics other than the traffic light. In this configuration, the feature is different between the first guide and the second guide so that the user can recognize the feature that could not be recognized by the first guide by the second guide. It is.

  In the present embodiment, the input unit 120 may receive an input of a guidance type together with a guidance request from the user. In this case, when the guidance unit 110 receives a guidance request and type from the user via the input unit 120, the guidance unit 110 performs the second guidance using the feature of the guidance point corresponding to the type. The type of guidance specifically refers to which features are used for guidance. Signal guidance using traffic lights, number of front roads using front roads, and facility guidance using facilities. It is desirable that at least one of them is included.

  If there is no feature corresponding to the user's request at the guidance point, the fact may be notified, or input for a feature that does not exist at the guidance point may not be received in advance. Also good. In this configuration, the second guidance is performed using the feature desired by the user.

  In the present embodiment, the setting unit 130 is an arbitrary component. The setting unit 130 sets the priority order of guidance types. In this case, when the guidance unit 110 receives a guidance request from the user via the input unit 120, the guidance unit 110 provides the second guidance using the feature of the guidance point corresponding to the next rank type of the first guidance type. Do it.

  In the setting unit 130, a higher priority may be set for a feature with good visibility or a feature that stands out. Note that the setting of the priority order to the setting unit 130 may be set in advance at the time of manufacturing, may be set to be appropriately changeable based on an input from the user, and the number of requests from the user may be set. It may be set in descending order. In this configuration, a feature effective for the user is used for guidance according to the priority order, and allows the user to quickly recognize the feature and the guidance route.

  Moreover, in this Embodiment, the guidance part 110 may display a guidance image using the display part 113 as the output part 112, and may guide a guidance point. Specifically, the display unit 113 is a display. In this case, when the guidance unit 110 receives a guidance request from the user through the input unit 120, the guidance unit 110 adds an icon indicating a feature of a guidance point not used for the first guidance to the guidance image of the first guidance. The added guidance image may be displayed on the display unit 113 to perform the second guidance. Specifically, the icon indicates a feature such as a traffic light with a symbol, a picture, or a figure.

  To give a specific example, when the first guidance with an icon indicating a traffic light is being performed, the guidance unit 110 indicates a nearby facility in addition to the icon indicating the traffic light when receiving a guidance request. Add an icon and give the second guide. This configuration makes it possible to sequentially add information to the user and present information to the user.

  In the present embodiment, when the guide unit 110 displays a guide image on the display unit 113 to guide a guide point, when the input unit 120 receives a guide request from the user, the guide unit 110 The icon indicating the feature of the guide point used for the first guidance is deleted from the guide image, and the icon indicating the feature of the guide point not used for the first guidance is added to the guide image. May be displayed on the display unit 113 to provide the second guidance.

  To give a specific example, the guide unit 110 deletes the icon indicating the traffic light when the first guidance with the icon indicating the traffic light is being performed and receives the guidance request, Only the icon to show is added and 2nd guidance is performed. This configuration makes it possible to sequentially present only information different from the first guidance to the user.

  Moreover, in this Embodiment, the guidance part 110 may output a guidance audio | voice using the audio | voice output part 114 as the output part 112, and may perform guidance of a guidance point. Specifically, the audio output unit 114 is a speaker. In this case, when the guidance unit 110 receives a guidance request from the user through the input unit 120, the guidance unit 110 outputs guidance voices that guide the features at the guidance point not used for the first guidance during the first guidance. The second guidance may be performed by adding the guidance voice to the guidance voice and outputting the added guidance voice from the voice output unit 114.

  To give a specific example, when the first guidance for outputting the guidance voice using the traffic light is being performed, the guidance unit 110 receives the guidance request when the guidance request is received, A guidance voice using the facility is added to provide the second guidance. This configuration makes it possible to sequentially add information to the user and present information to the user.

  In the present embodiment, when the guidance unit 110 outputs guidance voice from the voice output unit 114 to guide the guidance point, the guidance unit 110 receives the guidance request from the user via the input unit 120 and receives the first guidance. Alternatively, the second guidance may be performed by outputting only a guidance voice for guiding a feature at a guidance point that is not used for the navigation.

  As a specific example, when the first guidance for outputting a guidance voice using a traffic light is performed, the guidance unit 110 does not use the guidance voice using a traffic light when receiving a guidance request. The second guidance is provided by guidance voice using only surrounding facilities. This configuration makes it possible to sequentially present only information different from the first guidance to the user.

  Moreover, in this Embodiment, the guidance part 110 should just perform 1st guidance, when a mobile body approaches within the predetermined range from a guidance point. In this case, the input unit 120 may receive a guidance request from the user from the start of the first guidance until the moving body passes the guidance point. Note that the point guide device 100 may be built in a portable device that can be carried by the user, in addition to the device installed in a vehicle or the like. That is, the moving body referred to here includes the user itself in addition to the vehicle.

  Moreover, in this Embodiment, the input part 120 is good also as being able to receive a guidance request | requirement from a user in multiple times from the start of 1st guidance until a mobile body passes a guidance point. In this case, every time the guidance unit 110 receives a guidance request from the user via the input unit 120, the guidance unit 110 may perform guidance on the guidance point with contents different from the guidance so far. Specifically, the guidance unit 110 sequentially provides guidance as third guidance, fourth guidance, fifth guidance,... According to the number of times a guidance request is received from the user by the input unit 120. .

  In the configuration in which the priority is set in the setting unit 130, when there is no feature corresponding to the next rank type, the guide unit 110 further selects a feature corresponding to the next rank type. Use it for guidance. This configuration makes it possible to change the guidance content until the user can recognize the guidance route.

(Point guide device search processing procedure)
Next, the search processing procedure of the point guide device 100 will be described with reference to FIG. FIG. 2 is a flowchart illustrating an example of a search processing procedure of the point guide device 100 according to the present embodiment.

  In the flowchart of FIG. 2, it is assumed that the point guide device 100 performs route guidance to the destination. The point guidance apparatus 100 first determines whether or not the mobile object is located at the guidance point (step S201). Note that the determination in step S201 is specifically a determination of whether or not the mobile object is located within a predetermined range from the guidance point. In step S201, it is in a standby state until the moving body is located at the guidance point (step S201: No loop). When the moving body is located at the guidance point (step S201: Yes), the first guidance is performed (step S202). ).

  Then, it is determined whether a guidance request has been accepted (step S203). In step S203, when a guidance request is received (step S203: Yes), second guidance is performed (step S204). And it is judged whether it passed the guidance point (step S205).

  In step S205, when it is determined that the vehicle has not passed the guidance point (step S205: No), the guidance is continued (step S206), and the process proceeds to step S203. On the other hand, when the guidance request is not accepted in step S203 (step S203: No), the process proceeds to step S205. If it is determined in step S205 that the guide point has been passed (step S205: Yes), the series of processing ends.

  In the above description, for the sake of convenience, the two guides, the first guide and the second guide, are described. However, in step S203, the second guide is provided when the guide request is received. There is. In this case, the guidance in step S204 is the third guidance. In addition, when the third guidance is performed and the guidance request is accepted, the guidance in step S204 becomes the fourth guidance. Accordingly, the “second guidance” in step S204 is, in other words, “a different guidance”.

  As described above, the point guidance device 100 according to the present embodiment performs the second guidance with the content different from the first guidance when the guidance request is received after the first guidance. . Therefore, for the user, even if the route to be guided cannot be recognized by the first guidance, the route to be guided can be recognized by the second guidance, and the user can reach the destination without hesitation. Can be reached. Thus, the point guidance apparatus 100 concerning this Embodiment can perform the guidance containing the information which a user desires according to the request | requirement from a user.

  Specifically, when there is a shield or the like that reduces the visibility of the feature in front of the feature used for the first guidance, or when the feature is difficult to see due to direct sunlight, etc. In a situation where an object cannot be recognized, if the second guidance is performed using a feature different from the feature used for the first guidance, the user can easily recognize the feature. At the same time, the route to be guided can be recognized.

  Examples of the present invention will be described below. In the present embodiment, an example in which the point guidance device 100 of the present invention is implemented by a navigation device mounted on a vehicle will be described.

The input device 410 may be realized by any one of a remote controller, a keyboard, a mouse, and a touch panel, or may be realized by a plurality of forms.

  The video I / F 411 is connected to the display 412. Specifically, the video I / F 411 includes, for example, a graphic controller that controls the entire display 412, a buffer memory such as a VRAM (Video RAM) that temporarily records image information that can be displayed immediately, and a graphic controller. Based on the output image data, the display 412 is configured by a control IC or the like.

  The display 412 displays icons, cursors, menus, windows, or various data such as characters and images. On the display 412, the map data described above is drawn two-dimensionally or three-dimensionally. The map data displayed on the display 412 can be displayed with a mark representing the current location of the vehicle on which the navigation device 300 is mounted. The current position of the vehicle is calculated by the CPU 401.

  As this display 412, for example, a CRT, a TFT liquid crystal display, a plasma display, or the like can be adopted. The display 412 is installed near the dashboard of the vehicle, for example. A plurality of displays 412 may be installed in the vehicle, for example, in the vicinity of the dashboard of the vehicle or in the vicinity of the rear seat of the vehicle.

  The communication I / F 413 is connected to a network via wireless and functions as an interface between the navigation device 300 and the CPU 401. The communication I / F 413 is further connected to a communication network such as the Internet via wireless, and also functions as an interface between the communication network and the CPU 401.

(Example of priority information set in the navigation device)
An example of priority information set in the navigation device 300 according to the present embodiment will be described with reference to FIG. FIG. 5 is an explanatory diagram of an example of priority order information set in the navigation device 300 according to the present embodiment.

  In FIG. 5, the setting information 500 describes a priority order 501, a feature object 502, and a detailed setting 503. The priority order 501 indicates the order of the feature 502 used at the time of guidance. The feature object 502 is a landmark near the guide point, and in accordance with the priority order 501, the traffic light, the facility, and the number of roads in the foreground are described. In addition, the feature 502 can be set with a crossover, a railroad crossing, a sign, and the like.

  In the detailed setting 503, for each feature 502, a detailed priority order 504 indicating a priority order and a corresponding detailed feature 505 are described. For example, the traffic signal of the feature 502 will be described as an example. The detailed priority order 504 indicates the order of the traffic lights used at the time of guidance. The detailed feature 505 is a unique landmark in the vicinity of the intersection, and according to the detailed priority 504, the traffic signal at the intersection (guide point) and the traffic signal at the near intersection are described.

  By setting the setting information 500 as described above, it is possible to provide guidance by changing the guidance contents in the order of traffic lights, facilities, and the number of roads in the front during guidance processing described later. The order of guidance may be the order of the detailed priority 504 of the feature 502 having the higher priority 501 (the order of the traffic light at the intersection, the traffic light at the front intersection, the convenience store,...), Or the feature 502. It is good also as the order of the detailed priority 504 for every (the order of the traffic signal of the said intersection, a convenience store, the nearest road, ...).

  Such setting information 500 may be set for each road. Specifically, the setting information 500 may be set for each point such as “National Route ○ Route, A Intersection, Uphill”.

(An example of processing for receiving a guidance request made by the navigation device)
Next, an example of processing for receiving a guidance request performed by the navigation device 300 according to the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart illustrating an example of a process of receiving a guidance request performed by the navigation device 300 according to the present embodiment.

  In FIG. 6, it is assumed that the navigation device 300 provides guidance for a route to the destination. The navigation device 300 first determines whether or not the vehicle is located at the guidance point (step S601). Note that the determination in step S601 is specifically a determination of whether or not the vehicle is located within a predetermined range from the guidance point.

  In step S601, the vehicle is on standby until the vehicle is positioned at the guidance point (step S601: No loop). When the vehicle is positioned at the guidance point (step S601: Yes), the first guidance is performed (step S602). The first guidance is, for example, an enlarged display of the display screen.

  And it is judged whether it is a guidance point with a feature (step S603). If it is determined in step S603 that the guide point has a characteristic object (step S603: Yes), a notification for accepting a guide request is issued (step S604), and the series of processing ends.

  Specifically, in step S604, for example, a message such as “Do you want to display a landmark?” Or voice output is displayed. In step S604, a notification for accepting the type of guidance may be given. The type of guidance is which feature is used for guidance, and is traffic light guidance, front road number guidance, and facility guidance. Note that a display screen that accepts an input of a guidance type will be described later with reference to FIGS.

  On the other hand, if it is determined in step S603 that it is not a guide point with a feature (step S603: No), a series of processing ends. The processing after the notification of accepting the guidance request in step S604 will be described below with reference to FIG.

(Example of point guidance processing performed by the navigation device)
Next, an example of the spot guidance process performed by the navigation device 300 according to the present embodiment will be described with reference to FIG. FIG. 7 is a flowchart illustrating an example of the spot guidance process performed by the navigation device 300 according to the present embodiment. In the flowchart shown in FIG. 7, processing in the case of using a feature according to the priority order will be described.

  In FIG. 7, the navigation apparatus 300 is in a state after a notification for accepting a guidance request is made at a guidance point, and determines whether or not a guidance request has been accepted (step S701). The input method for accepting the guidance request in step S701 is operation input or voice input. If it is determined in step S701 that a guidance request has been received (step S701: Yes), a high priority feature is extracted (step S702). A feature with a high priority is a traffic light if the setting information 500 shown in FIG. 5 is used.

  Then, an icon corresponding to the extracted feature is displayed (step S703). In step S703, a message such as “Do you want to display another landmark?” Is displayed or output as a notification that the guidance request can be accepted together with the display of the icon. Moreover, what is necessary is just to output the guidance sound using a traffic light, when performing guidance by an audio | voice in step S703.

  Then, it is further determined whether a guidance request has been received (step S704). The acceptance input method in step S704 may be an operation input or a voice input as in step S701. If it is determined in step S704 that a further guidance request has been received (step S704: Yes), the next highest priority feature is extracted (step S705). The next highest priority feature is a facility when the setting information 500 shown in FIG. 5 is used.

  Then, an icon corresponding to the extracted feature is added and displayed (step S706). That is, in step S706, the signal icon and the facility icon are displayed simultaneously. Further, in step S706, not only adding and displaying an icon, but it is also possible to delete the previously displayed icon and display only the icon extracted this time. That is, only the facility icon may be displayed without displaying the signal icon.

  Further, in the case where guidance by voice is performed in step S706, guidance voice using a traffic light and a facility may be output. After the process of step S706, the process proceeds to step S704.

  On the other hand, when the guidance request is not accepted in step S701 (step S701: No), it is determined whether or not the guidance point has been passed (step S707). In step S707, until it passes through the guide point (step S707: No), the process proceeds to step S701, and when it is determined that the guide point is passed (step S707: Yes), the series of processing ends.

  In step S704, when a guidance request is not accepted (step S704: No), it is determined whether or not a guidance point has been passed (step S708). In step S708, until it passes through the guidance point (step S708: No), the process proceeds to step S703, and when it is determined that the guidance point is passed (step S708: Yes), the series of processing ends.

  According to the processing described above, guidance according to the priority order is performed for the amount of guidance request received until the guidance point is passed. Specifically, guidance is provided by adding icons. Therefore, the user can make a guidance request until the feature is recognized, and the user can follow the guidance route without getting lost by using the recognized feature as a landmark.

(Another example of point guidance processing performed by the navigation device)
Next, another example of the spot guidance process performed by the navigation device 300 according to the present embodiment will be described with reference to FIG. FIG. 8 is a flowchart illustrating another example of the spot guidance process performed by the navigation device 300 according to the present embodiment. In the flowchart shown in FIG. 8, processing in the case of using a feature according to the type of guidance requested by the user will be described.

  In FIG. 8, the navigation apparatus 300 is in a state where a notification for accepting an input of a guidance type has been made at a guidance point, and determines whether or not an input of a guidance type has been accepted (step S801). The details of the display screen that accepts the input of the guidance type will be described later with reference to FIGS.

  The types of guidance are, for example, traffic light guidance, front road number guidance, and facility guidance. The input method for accepting the guidance type in step S801 is operation input or voice input. If it is determined in step S801 that an input of a guidance type has been received (step S801: Yes), the received type of feature is extracted (step S802). Specifically, when the traffic signal guidance is received, the traffic signal at the guidance point is extracted.

  Then, an icon corresponding to the extracted type of feature is displayed (step S803). In step S803, an icon is displayed and a notification that can accept an input of a guidance type is given. Further, in the case where guidance by voice is performed in step S803, guidance voice using a traffic light may be output.

  Then, it is further determined whether or not an input of guidance type has been accepted (step S804). The input method of acceptance in step S804 may be operation input or voice input as in step S801. If it is determined in step S804 that an input of a guidance type has been received (step S804: Yes), the received type of feature is extracted (step S805). Specifically, when facility guidance is received, facilities around the guidance point are extracted.

  Then, an icon corresponding to the extracted type of feature is added and displayed (step S806). That is, in step S806, a traffic light icon and a facility icon are displayed simultaneously. Further, in step S806, not only adding and displaying an icon, but it is also possible to delete the previously displayed icon and display only the icon extracted this time. That is, only the facility icon may be displayed without displaying the signal icon.

  Further, in the case where guidance by voice is performed in step S806, guidance voice using a traffic light and a facility may be output. After the process of step S806, the process proceeds to step S804.

  On the other hand, if no guidance type input is accepted in step S801 (step S801: No), it is determined whether or not the guidance point has been passed (step S807). In step S807, the process proceeds to step S801 until it passes through the guide point (step S807: No), and if it is determined that the guide point has been passed (step S807: Yes), a series of processing ends.

  If no guidance type input is accepted in step S804 (step S804: No), it is determined whether or not the guidance point has been passed (step S808). In step S808, the process proceeds to step S803 until it passes through the guide point (step S808: No). When it is determined that the guide point has been passed (step S808: Yes), the series of processing ends.

  According to the above-described processing, the guidance corresponding to the input of the guidance type is performed until the guidance point is passed. Specifically, guidance is provided by adding icons. Therefore, the user can make a request for the type of guidance until the feature is recognized, and can use the recognized feature as a mark to follow the guidance route without getting lost.
