(Embodiment)
(Functional configuration of the route guidance device)
First, the functional configuration of the route guidance device 100 according to the embodiment of the present invention will be described. FIG. 1 is a block diagram of a functional configuration of the route guidance device according to the embodiment.

  In FIG. 1, the route guidance device 100 includes a display unit 101, a drive unit 102, a detection unit 103, an acquisition unit 104, a determination unit 105, and a control unit 106. The display unit 101 includes a display screen that displays map data. Here, the map data is stored in a storage unit (not shown). The map data includes road network data composed of nodes and links, and image data drawn using features relating to facilities, roads, and other terrain (mountains, rivers, land). The map data may include text information, information such as facility names and addresses, road and facility images, and the like.

  The display unit 101 displays guidance information on the guidance route to the destination point of the mobile object. The guidance information is information on guidance guidance related to the route, and is, for example, guidance that indicates the direction of the right / left turn displayed at a guidance point such as a right / left turn point. In addition, the guidance information may be configured to output audio information together with the display, or may be configured to output only audio information. The voice information includes, for example, guidance for turning left and right such as “Turn left 300m”, and guidance for changing lanes such as “Please move to the left lane and enter the expressway”.

  Further, the display unit 101 may be configured to change the color and brightness of the display screen under the control of the control unit 106 described later. Specifically, for example, when the guidance information is not displayed, the display screen may be darkened or a screen saver may be activated. Further, the display unit 101 may output a ringing tone or the like when displaying the guidance.

  The drive unit 102 moves the display unit 101. For example, the display screen included in the display unit 101 is moved under the control of the control unit 106 described later. Specifically, for example, the display screen is moved in the vertical direction or the horizontal direction. Further, the drive unit 102 moves the display screen in the direction of rotation. Further, the drive unit 102 may move the display screen stored inside the apparatus in a direction in which the display screen appears outside. Here, the direction in which the display screen appears is a direction in which the display screen is moved so as to appear outside from a casing (not shown) that stores the display screen.

  The detection unit 103 detects a guide point on the guidance route. Specifically, for example, a guidance point for displaying guidance information is detected from the guidance route. The detection unit 103 may detect all the guidance points when starting route guidance, or may sequentially detect every predetermined section. In addition, for example, when the moving body has left the guidance route and the route is searched again, the detection unit 103 may re-detect the guidance point.

  The acquisition unit 104 acquires the current location of the moving object. For example, the current position of the moving body is acquired according to the output value from the acceleration sensor or the vehicle speed sensor that detects the behavior of the moving body in addition to the GPS signal received from the GPS satellite. May be.

  The determination unit 105 determines whether or not the current location of the moving body acquired by the acquisition unit 104 is within a predetermined distance from the guide point detected by the detection unit 103. Further, the determination unit 105 may change the predetermined distance serving as a determination reference according to the moving speed of the moving object, the weather, and the time. Specifically, for example, the predetermined distance may be increased when the moving speed is high, when it is raining, or when it is nighttime.

  When the determination unit 105 determines that the distance is within the predetermined distance, the control unit 106 controls the drive unit 102 to move the display screen to a position where the guide information is presented to the passenger of the moving body. The position where the guidance information is presented to the mobile passenger is, for example, the position where the angle of the display screen is directed toward the passenger, the position where the display screen is close to the passenger, the position where the display screen is moved, and the display This is the position where the display screen is placed in the passenger's field of view, such as the position where the screen is removed from the casing. Specifically, for example, the control unit 106 moves the display screen in the vertical direction or the horizontal direction under the control of the driving unit 102. In addition, the control unit 106 moves the display screen in the direction of rotation under the control of the driving unit 102. Further, the control unit 106 may move the display screen stored inside the apparatus in a direction to appear outside under the control of the driving unit 102. In addition, the control unit 106 may change the color or brightness of the display screen under the control of the display unit 101.

(Route guidance processing procedure of the route guidance device)
Next, a route guidance processing procedure of the route guidance device 100 will be described. FIG. 2 is a flowchart showing a route guidance processing procedure of the route guidance device. In the flowchart of FIG. 2, first, the system waits until the route guidance is started (step S201: No loop). It detects (step S202).

  Next, the acquisition unit 104 acquires the current location of the moving object (step S203). Then, the determination unit 105 determines whether or not the current location of the moving body acquired in step S203 is within a predetermined distance from the guidance location detected in step S202 (step S204). If it is within a predetermined distance from the guide point in step S204 (step S204: Yes), the control unit 106 controls the drive unit 102 to move the display screen to a position where the guide information is presented to the passenger (step S205). A series of processing ends.

  On the other hand, when it is not within the predetermined distance from the guidance point in step S204 (step S204: No), the process returns to step S203, and the subsequent processing is repeated. In step S204: No, if it is not within a predetermined distance from the guidance point, the display screen may be moved to a position where the guidance information is not presented to the passenger. Specifically, the location where the guidance information is not presented to the passenger is, for example, the location where the display screen is moved away from the passenger, the location where the display screen is moved, the location where the display screen is stored, etc. This is the position to remove the display screen from the field of view.

  In the flowchart of FIG. 2, when it is not within the predetermined distance from the guidance point in step S204: No, the process returns to step S203. However, the present invention is not limited to this. For example, you may output the audio | voice information showing that it is not a guidance point. Specifically, for example, voice information such as “It ’s been a while” may be output.

  As described above, according to the route guidance device 100 of the present embodiment, it is determined whether or not the current location of the moving object acquired by the acquisition unit 104 is within a predetermined distance from the guidance point detected by the detection unit 103. When it is determined by the unit 105 and it is determined that the distance is within the predetermined distance, the control unit 106 can control the drive unit 102 to move the display screen to a position where the guide information is presented to the passenger of the moving body. Therefore, when the guide point approaches, the display screen can be moved to a position where guide information is presented to the passenger.

  Accordingly, the user can recognize that he / she has approached the guidance point without always paying attention to the display screen or listening carefully to the voice information, so that he / she can not miss the guidance information. In addition, the display screen is moved to a position that does not interfere with driving until the guide point is approached, so that safe driving can be performed without being distracted by the display screen.

  Moreover, according to the route guidance device 100 of the present embodiment, the control unit 106 can move the display screen in the vertical direction or the horizontal direction under the control of the drive unit 102. Thus, for example, when the display screen is installed on the dashboard, the user can recognize that the display point is approaching because the display screen moves when approaching the guide point. You can't miss it. In addition, the display screen is moved to a position that does not interfere with driving until the guide point is approached, so that safe driving can be performed without being distracted by the display screen.

  Moreover, according to the route guidance device 100 of the present embodiment, the control unit 106 can move the display screen in the direction of rotation under the control of the drive unit 102. As a result, for example, when the display screen is installed on the dashboard, the user can recognize that the display point is approached because the display screen occurs when approaching the guide point. I can't miss it. Further, since the display screen is moved to a position where it does not interfere with driving until the guide point is approached, safe driving can be performed without being distracted by the display screen.

  Further, according to the route guidance device 100 of the present embodiment, the control unit 106 can move the display screen stored inside the device in a direction to appear outside under the control of the driving unit 102. Thus, for example, when a casing for storing a display screen is provided, the user can recognize that the display point appears when approaching the guide point, and thus the user can recognize that the guide point has been approached. You can not miss the information. Further, since the display screen is stored until the guide point is approached, safe driving can be performed without being distracted by the display screen.

  Moreover, according to the route guidance device 100 of the present embodiment, the control unit 106 can change the color or brightness of the display screen under the control of the display unit 101. As a result, even if the user does not move the display screen, for example, the display screen changes when approaching the guide point, so that the user can recognize that he has approached the guide point and does not miss the guide information. Can do. Further, since the display screen is not displayed or darkened until approaching the guide point, the display screen is not distracted and safe driving can be performed.

Can be executed by the route guidance processing procedure.

(Contents of processing of navigation device 300)
Next, the processing contents of the navigation device 300 will be described. FIG. 4 is a flowchart showing the contents of processing of the navigation device. In the flowchart of FIG. 4, first, it waits until route guidance is started (step S401: No loop), and when route guidance is started (step S401: Yes), a guide point on the guidance route is detected (step S401). S402).

  Next, the current location of the vehicle is acquired (step S403), and it is determined whether or not the current location of the vehicle acquired in step S403 is within a predetermined distance to the guidance location detected in step S402 (step S404). If it is not within the predetermined distance to the guide point in step S404 (step S404: No), the display 313 is tilted (step S405), the process returns to step S403, and the subsequent processing is repeated.

  On the other hand, if it is within the predetermined distance to the guide point in step S404 (step S404: Yes), the display 313 is raised (step S406), and guidance is provided (step S407). In step S407, the guidance information displays guidance information on the display 313 generated in step S406. Moreover, you may output audio | voice information with a display.

  Then, it is determined whether or not the destination point has been reached (step S408). If the destination point has been reached (step S408: Yes), the series of processing is terminated. On the other hand, when it does not arrive at the destination point in step S408 (step S408: No), the process returns to step S403, and the subsequent processing is repeated.

  In the flowchart of FIG. 4, the display 313 is tilted in step S405, but the present invention is not limited to this. Specifically, for example, if the display has already been tilted, it is left in the tilted state. Furthermore, although mentioned later for details, the display 313 may be moved to the up-down direction or the left-right direction, for example, and may be moved to the direction stored in a storage space (casing).

  Further, for example, when the display 313 cannot be driven, the display color of the display 313, the brightness of the display, and the like may be changed. Furthermore, for example, when it is not within a predetermined distance to the guidance point, the screen saver may be activated, and when the distance to the guidance point is within the predetermined distance, the activation of the screen saver may be stopped. In this manner, the passenger is made to recognize that the display method of the display 313 has changed.

  Moreover, in the flowchart of FIG. 4, when it is not within the predetermined distance to the guide point in Step S404: No, the display 313 is brought down in Step S405, but this is not restrictive. For example, when the display 313 is turned down, voice information indicating that there is no guidance point for a while, such as “It ’s been a while”, may be output.

(About the drive direction of the display)
Next, the driving direction of the display 313 will be described with reference to FIG. FIG. 5 is an explanatory diagram showing the driving direction of the display. In FIG. 5, a display 313 provided in the navigation device 300 is shown. In FIG. 5, the display 313 is at a position 501 at the time of guidance. The position 501 at the time of guidance guidance represents the position of the display 313 when the guidance guidance is displayed at the guidance point on the route guidance. Further, the position 501 at the time of guidance guidance is directed to the direction in which guidance guidance is presented to the driver.

  Here, as an example of the driving direction of the display 313 when it is not within the predetermined distance to the guide point in Step S404: No, there is a slide. The slide moves the display 313 in the vertical direction and the horizontal direction. For example, the display 313 is translated in the vertical direction or the horizontal direction without changing the angle of the display 313. Specifically, for example, the display 313 is moved to the position 502 slid in the horizontal direction.

  Another example of the driving direction of the display 313 is rotation. For example, the rotation changes the angle of the display 313 with the lower side of the display 313 as a base point, and tilts or raises the display 313. Specifically, for example, the display 313 is moved to a position 503 rotated in the forward direction.

  In addition, although not shown, the display 313 can also be slid and rotated when the display 313 is an on-dash display fixed to the dashboard. In this case, a drive unit is provided between the dashboard and the on-dash display, and the on-dash display is moved to a slid position and a rotated position by controlling the drive unit.

  Furthermore, another example of the driving direction of the display 313 is storage. For storage, for example, the display 313 is moved up and down. Further, for example, the display 313 is stored in a box-shaped casing in which the display 313 is stored. Specifically, for example, the display 313 is moved to the position 504 stored in the casing. In this case, the display 313 may be slid and rotated according to the position and size of the casing and stored.

  In FIG. 5, the driving direction from the position 501 at the time of guidance is described. However, when the display 313 is raised in step S <b> 406, the position 503 is slid horizontally, the position 503 is rotated forward, and the casing. Is moved to a position 501 at the time of guidance. As a result, the user can recognize that the user has approached the guidance point for guidance by the movement of the display 313. Therefore, it is possible to recognize that the user has approached the guidance point without frequently checking the display 313 or listening carefully to the voice information, so that the guidance information can not be missed.

  As described above, according to the navigation device 300 of the present embodiment, the determination unit 105 determines whether or not the current location of the moving object acquired by the acquisition unit 104 is within a predetermined distance from the guidance point detected by the detection unit 103. When it is determined that the distance is within the predetermined distance, the control unit 106 can control the drive unit 102 to move the display screen to a position where guidance information is presented to the passenger of the moving body. Therefore, when the guide point approaches, the display screen can be moved to a position where guide information is presented to the passenger.

  Accordingly, the user can recognize that he / she has approached the guidance point without always paying attention to the display screen or listening carefully to the voice information, so that he / she can not miss the guidance information. In addition, the display screen is moved to a position that does not interfere with driving until the guide point is approached, so that safe driving can be performed without being distracted by the display screen.

  Further, according to the navigation apparatus 300 of the present embodiment, the control unit 106 can move the display screen in the vertical direction or the horizontal direction under the control of the drive unit 102. Thus, for example, when the display screen is installed on the dashboard, the user can recognize that the display point is approaching because the display screen moves when approaching the guide point. You can't miss it.
