Description

Technical Field

[0001] This application relates to the technical field of display control for switching and displaying an image including a route.

Background Art

[0002] Conventionally, a car navigation device provides route guidance while displaying on a display unit a map showing a route from the current position to the destination. On this map, a line indicating the route (hereinafter sometimes referred to as a "route line") is emphasized and displayed, and the shape of the line represents a point on the route (for example, an intersection where a right or left turn should be made, a point where the route bends). In addition to the map showing the route, a point information notation indicating information related to a point on the route (information indicating a point name, a distance from the current position to the point, etc.) is displayed on the display unit. Based on the map showing the route and the point information notation, the user can obtain the point where a right or left turn should be made and information related to the point, and can move along the route more smoothly.

[0003] On the other hand, a car navigation device has an audio function, a TV function, etc., and can display audio information (information such as an artist name, an album name, a song name) and TV video on the display unit. However, the display area of the display unit is limited, and the amount of information that can be displayed is limited.

[0004] Therefore, if the route can be simplified and displayed to reduce the area for displaying the route on the display unit and expand the area for displaying other information, more information can be provided to the user. Patent Document 1 discloses a method of representing a route by a straight line as a method of simplifying a route. This method is also adopted when guiding a highway in a conventional car navigation device.

[0012] A mode for carrying out the invention of the present application will be described with reference to FIG. 1.

[0013] As shown in FIG. 1, the display control device 100 includes a first processing means 101 and a second processing means 102.

[0014] The first processing means 101 causes a display unit to display a first image including a first line indicating a route and expressing a point on the route by the shape of the line, and a point information notation representing information related to the point.

[0015] The second processing means 102 causes the display unit to display a second image that is switched from the first image and that displays a second line indicating the route and having a shape different from the shape of the first line, with the point and the point information notation associated with each other.

[0016] According to the display control device 100, from a first image including a first line indicating a route and expressing a point on the route by the shape of the line, and a point information notation representing information related to the point, it switches to a second image that displays a second line indicating the route and having a shape different from the shape of the first line, with the point on the route and the point information notation associated with each other. Therefore, even in the switched image, the user can easily grasp the correspondence between the point on the route and the point information notation. **Examples**

[0017] Next, examples corresponding to the above-described embodiments will be described. Note that the examples described below are examples when the invention of the present application is applied to the in-vehicle device 200.

[0018] [Configuration of In-vehicle Device 200] With reference to FIG. 2, the configuration of the in-vehicle device 200 in this embodiment will be described. As shown in FIG. 2, the in-vehicle device 200 includes a control unit 211, a storage unit 212 composed of an HDD (Hard Disk Drive), an SSD (Solid State Drive), etc., an input unit 213 composed of a keyboard, a remote controller, a touch panel, etc., a display unit 214, a bus line 215, an input / output interface unit 220, a vehicle speed sensor 221, an angular velocity sensor 222, an acceleration sensor 223, a steering angle sensor 224, and a GNSS (Global Navigation Satellite System) receiver 225.

[0019] The vehicle speed sensor 221 detects the current speed of the vehicle using, for example, speed detection processing using a vehicle speed pulse obtained from the vehicle on which the in-vehicle device 200 is mounted, and outputs speed data. The angular velocity sensor 222 detects, for example, the angular velocity of the vehicle's direction change, and outputs angular velocity data and relative azimuth data per unit time. The acceleration sensor 223 detects, for example, the acceleration of the vehicle in the front-rear direction, and outputs acceleration data per unit time. The steering angle sensor 224 detects the steering angle of the vehicle and outputs steering angle data. The GNSS receiver 225 receives navigation radio waves from GNSS satellites and outputs GNSS positioning data.

[0020] The storage unit 212 stores data for displaying various images (including the detailed route image and the simple route image described later) on the display unit 214. For example, map data for displaying a map, map information used when searching for a route, road link information, etc. are stored. Also, the storage unit 212 stores various programs such as an operating system and application programs. In particular, the storage unit 212 stores a display control program for switching and displaying the detailed route image and the simple route image described later on the display unit 214. Note that the various programs may be acquired from, for example, a server device or the like via a network, or may be read from those recorded on a recording medium such as a CD, DVD, or USB memory.

[0021] The input unit 213 receives the user's input operation and transmits an operation signal indicating the operation content to the control unit 211.

[0022] The display unit 214 displays an image based on the image data under the control of the control unit 211. The display unit 214 includes a graphics controller 214a, a buffer memory 214b composed of a memory such as VRAM (Video RAM), a display 214c composed of a liquid crystal display or the like, etc. In this configuration, the graphics controller 214a controls the entire display unit 214 based on the control data sent from the control unit 211 via the bus line 215. Also, the buffer memory 214b temporarily stores image data that can be immediately displayed. Then, an image is displayed on the display 214c based on the image data output from the graphics controller 214a.

[0023] The control unit 211 is composed of a CPU 211a that controls the entire control unit 211, a ROM 211b in which a control program for controlling the control unit 211 and the like are stored in advance, and a RAM 211c that temporarily stores various data. Then, the CPU 211a functions as various means by reading and executing various programs stored in the ROM 211b and the storage unit 212. The control unit 211 or the CPU 211a corresponds to a "computer".

[0024] In addition, the control unit 211 is connected to a vehicle speed sensor 221, an angular velocity sensor 222, an acceleration sensor 223, a steering angle sensor 224, and a GNSS receiver 225 via a bus line 215 and an input / output interface unit 220.

[0025] The control unit 211 performs satellite positioning based on GNSS positioning data, self-positioning based on speed data, angular velocity data, relative azimuth data, acceleration data, steering angle data, etc., or hybrid positioning combining these, and acquires current position information indicating the current position (latitude, longitude, altitude) of the host vehicle (sometimes referred to as the "own vehicle").

[0026] [2. Image switching control by the control unit 211] The control unit 211 controls the switching of the image displayed on the display 214c by transmitting the image data generated based on the map data and the like stored in the storage unit 212 and the control data regarding the image switching to the display unit 214. This control is performed by the control unit 211 executing a display control program. Hereinafter, with reference to FIG. 3, the image displayed on the display 214c and the image switching control by the control unit 211 will be described.

[0027] [2.1. Switching control from the detailed route image to the simple route image] FIG. 3 is a diagram showing an example of image transition when switching an image from a detailed route image to a simple route image. FIG. 3(A) is a diagram showing an example of the detailed route image 300A, and FIG. 3(F) is a diagram showing an example of the simple route image 300F. Further, FIGS. 3(B) to 3(E) are diagrams respectively showing examples of intermediate images 300B - 300E displayed during the process when the image is switched from the detailed route image 300A to the simple route image 300F.

[0028] The detailed route image 300A and the simple route image 300F are route guidance images for guiding the user to the destination, and respectively display a self - vehicle mark M indicating the self - vehicle equipped with the in - vehicle device 200 and route lines 301A, 301F.

[0029] In this embodiment, the user can select the display mode when the route guidance image is displayed on the display 214c from among two display modes. The display modes are a detailed mode and a simple mode. When the detailed mode is selected, the control unit 211 causes the detailed route image 300A to be displayed, and when the simple mode is selected, the control unit 211 causes the simple route image 300F to be displayed.

[0030] In this embodiment, the process of displaying the image before image switching (detailed route image 300A) is referred to as the first process, and the process of displaying the image after image switching (simple route image 300F) is referred to as the second process.

[0031] The detailed route image 300A includes a map depicting a route line 301A showing the route to the destination, and location information notations 311, 312, and 313 representing information about points on the route line 301A. In the detailed route image 300A, the map is always displayed with the traveling direction upward, and the own vehicle mark M is fixedly displayed at the position in the central lower part. The route line 301A overlaps the road on the map and is depicted, for example, in a color or thickness different from that of the road, enabling the user to distinguish between the road that is the route and the road that is not. Also, the route line 301A represents the points 321 and 322 on the route line 301A by its shape. That is, the route line 301A represents the points on the route by the bent parts of the line. The points on the route are, for example, intersections or landmarks where a right turn or a left turn is made.

[0032] The location information notations 311, 312, and 313 represent information about points on the route. In particular , the location information notation 311 represents information about the point 321, and the location information notation 312 represents information about the point 322.

[0033] Also, the order of the location information notations 311, 312, and 313 is based on the passing order from the current position of the own vehicle (hereinafter, "current position" indicates "the current position of the own vehicle") of the points to which each corresponds. In the detailed route image 300A of this embodiment, since the own vehicle mark M is fixedly displayed at the position in the central lower part, the location information notation 311 representing information about the point passed first, the location information notation 312 representing information about the point passed second, and the location information notation 313 representing information about the point passed third are displayed in order from the lower side.

[0034] Furthermore, in the example of the detailed route image 300A, the route line 301A cannot display the point where the route is changed next to the point 322 (the point passed through third) in the detailed route image 300A, but displays the point information notation 313 corresponding to the point where the route is changed next. At this time, since the point corresponding to the point information notation 313 is not represented in the shape of the route line 301A, the display form (for example, the color to be displayed) of the point information notation 313 may be different from that of the point information notations 311 and 312. Note that the number of point information notations to be displayed may be set to a set number with the upper limit being the number that can be displayed in the display area.

[0035] The information regarding the points represented by the point information notations 311, 312, and 313 is, for example, the direction to turn at the point, the distance from the current position to the point, the name of the point, and the like. In this embodiment, in the point information notation 311 corresponding to the point 321 passed through first, the direction to turn at the point 321, the distance from the current position to the point 321, and the name of the point 321 are denoted, and in the point information notations 312 and 313 corresponding to the points passed through second and third, the direction to turn at the point and the distance from the current position to the point are displayed. However, the point information notations corresponding to the points passed through second and later may denote the direction to turn at the point, the distance from the current position to the point, and the name of the point, or may denote a part of these.

[0036] When the user performs an operation to switch the display mode from the detailed mode to the simple mode, the control unit 211 switches the image from the detailed route image 300A to the simple route image 300F.

[0037] The simple route image 300F includes a route line 301F that is a straight line indicating the route to the destination, and location information notations 311, 312, 313 representing information about points on the route. When comparing the detailed route image 300A and the simple route image 300F, in the detailed route image 300A, the route line 301A represents points 321, 322 on the route by its shape, while in the simple route image 300F, the route line 301F does not represent points 321, 322 on the route by its shape. Also, a map is not displayed in the simple route image 300F. Furthermore, regarding the location information notations 311, 312, 313, the display form and display position are not changed between the detailed route image 300A and the simple route image 300F. By not changing the display form and display position of the location information notations 311, 312, 313, it is possible to make it less likely for the user to lose sight when the image switches from the detailed route image 300A to the simple route image 300F. Note that it may be such that at least one of the display form or the display position is displayed substantially the same, and in this case, it is possible to prevent the user from being confused more than when both the display form and the display position change.

[0038] Since the simple route image 300F does not represent points 321, 322 on the route by the shape of the route line 301F, it is difficult for the user to grasp the correspondence with the location information notations 311, 312. Therefore, the control unit 211 determines points on the route line 301F that correspond to points 321, 322, and represents these points with location marks 331, 332. The location marks have a display form that allows the user to recognize at a glance that they are points on the route line 301F. Note that the location marks in this embodiment have a circular display form with a diameter longer than the thickness of the route line 301F, but other display forms may be used as long as they allow the user to easily recognize at a glance that they are points on the route line 301F.

[0039] The user can grasp the correspondence between the route line 301F and the location information notations 311 and 312 (that is, the location mark 331 corresponds to the location information notation 311, and the location mark 332 corresponds to the location information notation 312) based on the positional relationship between the location marks 331 and 332 and the self-vehicle mark M, and the positional relationship (order) of the location information notations 311 and 312. The simple route image 300F includes a connection line 341 connecting the location mark 331 and the location information notation 311, and a connection line 342 connecting the location mark 332 and the location information notation 312. Thereby, the user can clearly grasp that the location mark 331 corresponds to the location information notation 311 and the location mark 332 corresponds to the location information notation 312.

[0040] Here, a method for the control unit 211 to determine points on the route line 301F that correspond to the points of the locations 321 and 322 (the positions where the location marks are drawn) will be described. First, the control unit 211 determines a point on the route line 301F corresponding to the location 321 such that the length from the self-vehicle mark M to the location 321 in the detailed route image 300A is substantially the same as the length from the self-vehicle mark M to the location mark 331 in the simple route image 300F. Thereby, since the length to the first passed location in the detailed route image 300A and the simple route image 300F does not change, the user will not feel discomfort, and the image can be switched from the detailed route image 300A to the simple route image 300F.

[0041] Further, the control unit 211 determines a point on the route line 301F corresponding to the location 322 based on the length from the point represented by the location mark 331 on the route line 301F to the self-vehicle mark M, and the moving distances from the current position to the location 321 and from the location 321 to the location 322. In the example of FIG. 3, the moving distance from the current position to the location 321 is 300 m, and the moving distance from the location 321 to the location 322 is 180 m. Here, if the length from the point represented by the location mark 331 on the route line 301F to the self-vehicle mark M is 2.5 cm, a point 1.5 cm (= (2.5 × 180) / 300) ahead of the point represented by the location mark 331 is determined as the point corresponding to the location 322.

[0042] As the host vehicle moves, the control unit 211 repeatedly determines points on the route line 301F corresponding to the points 321 and 322, respectively, and changes the positions representing the point marks 331 and 332. Thereby, as the host vehicle moves, the positions of the point marks 331 and 332 move in a direction approaching the host vehicle mark M.

[0043] On the other hand, the control unit 211 does not immediately switch the image from the detailed route image 300A to the simple route image 300F, but instead switches and displays the images in the order of the detailed route image 300A, the intermediate images 300B - 300E, and the simple route image 300F.

[0044] The intermediate images 300B - 300E each display the host vehicle mark M and the route lines 301B - 301E indicating the route. The intermediate images 300B - 300E represent the process of changing from the shape of the route line 301A in the detailed route image 300A to the shape (linear shape) of the route line 301F in the simple route image 300F. Also, as shown in the intermediate image 300B and the intermediate image 300C, the map represented in the detailed route image 300A is gradually erased.

[0045] As described above, in the vehicle device 200 in this embodiment, the control unit 211 (an example of the "first processing means" and the "second processing means") causes the display 214c (an example of the "display unit") to display a detailed route image 300A (an example of the "first image") including a route line 301A (an example of the "first line") that is a line indicating a route and represents the points 321 and 322 on the route by the shape of the line, and point information notations 311 and 312 representing information related to the points 321 and 322, and causes the display 214c to display a simple route image 300F (an example of the "second image") that is switched from the detailed route image 300A and is displayed, and that displays a route line 301F (an example of the "second line") having a shape different from the shape of the route line 301A, with the points 321 and 322 associated with the point information notations 311 and 312.

[0046] Therefore, according to the in-vehicle device 200 in this embodiment, from the detailed route image 300A including the route line 301A and the location information notations 311 and 312, the route line 301F having a shape different from that of the route line 301A is switched to the simple route image 300F that is displayed with the locations 321 and 322 on the route associated with the location information notations 311 and 312. Thus, even in the switched image, the user can easily grasp the correspondence between the locations on the route and the location information notations.

[0047] Also, in the vehicle device 200 in this embodiment, in the second process, the control unit 211 causes to display the simple route image 300F including the location marks 331 and 332 (an example of "symbol") that indicate the correspondence between the points on the route line 301F corresponding to the locations 321 and 322 and the location information notations 311 and 312 related to the locations 321 and 322. Thereby, the user can easily grasp the correspondence between the locations on the route and the location information notations.

[0048] Furthermore, in the vehicle device 200 in this embodiment, the control unit 211 (determination processing means) performs a determination process of determining the positions of the points on the route line 301F based on the distances to the locations with reference to the current position. In the second process, the simple route image 300F that displays the location marks 331 and 332 at the determined positions is caused to be displayed. Thereby, the user can grasp the sense of distance from the current position to each location and the sense of distance between each location.

[0049] Moreover, in the vehicle device 200 in this embodiment, in the second process, the control unit 211 causes to display the simple route image 300F that displays the location information notations 311, 312, and 313 displayed in the simple route image 300F in at least one of a display form substantially the same as that of the location information notations 311, 312, and 313 displayed in the detailed route image 300A or a display position substantially the same. Thereby, it is possible to prevent the user from being confused due to a change in the display form regarding the location information notations 311, 312, and 313.

[0050] Furthermore, in the vehicle device 200 of the present embodiment, the length of the line indicating from the position (current position) of the own vehicle mark M on the route line 301A of the detailed route image 300A to the first passing point 321 is substantially the same as the length of the line indicating from the position (current position) of the own vehicle mark M on the route line 301F of the simple route image 300F to the point mark 331 representing the first passing point. Thereby, in the detailed route image 300A and the simple route image 300F, the length of the line indicating the first passing point from the current position by the route line 301A and the route line 301F does not change, and it is possible to prevent the user from being confused due to the change in the distance indicated by the line to the guiding point, that is, the scale change.

[0051] [3. Modification Example] Next, a modification example of the present embodiment will be described. Note that the modification examples described below can be combined as appropriate.

[0052] [3.1. Modification Example 1] In the above embodiment, as shown in FIG. 3(F), the connection lines 341 and 342 connecting the point marks 331 and 332 and the point information notations 311 and 312 are respectively displayed in the simple route image 300F. However, as shown in FIG. 4, the connection lines 341 and 342 may not be displayed. By displaying the point marks 331 and 332 and the point information notations 311 and 312 in the order based on the passing order from the current position, even if the connection lines 341 and 342 are not displayed, the correspondence relationship between the point marks 331 and 332 and the point information notations 311 and 312 can be grasped.

[0053] [3.2. Modification Example 2] In the above-described embodiment, as shown in FIG. 3(A), in the detailed route image 300A, although the point where the route is changed next to point 322 cannot be fully displayed on the detailed route image 300A by the route line 301A, the point information notation 313 corresponding to the point where the route is changed next is also displayed. Accordingly, as shown in FIG. 3(F), the point information notation 313 is also displayed in the simplified route image 300F. However, as shown in FIG. 5, the point information notation 313 regarding a point where no point mark is to be displayed may not be displayed. And when the control unit 211 can represent, by a point mark, the point where the route is changed next to point 322 as the vehicle moves, the control unit 211 will display the point mark and the point information notation 313 that represents information regarding the point indicated by the point mark.

[0054] [3.3. Modification Example 3] In the above-described embodiment, as shown in FIGS. 3(A) and (F), the point mark 331 is displayed so that the length from the vehicle mark M to point 321 in the detailed route image 300A is substantially the same as the length from the vehicle mark M to the point mark 331 in the simplified route image 300F, and the point mark 332 is displayed at a position reflecting the actual distances from the current position to points 321 and 322. However, the position where the point mark is displayed may be determined according to the number of point information notations displayed in the simplified route image 300F. For example, as shown in FIG. 6, when three point information notations are displayed, three point marks 331, 332, and 333 corresponding to points 321, 322, and 323 may be displayed so that their respective positions are equally spaced. In this case, even though the corresponding point mark is not displayed, the user will not feel uncomfortable with the fact that the point information notation is displayed.

[0055] [3.4. Modification Example 4] In the above embodiment, as shown in FIG. 3(F), the connection lines 341 and 342 connecting the point marks 331 and 332 and the point information notations 311 and 312 in the simple route image 300F are displayed horizontally, but the connection lines may be displayed obliquely. For example, as shown in FIG. 7, if the distance from the current position to the point indicated by the point information notation 311 is 300 m, the distance from the current position to the point indicated by the point information notation 312 is 400 m, and the distance from the current position to the point indicated by the point information notation 313 is 500 m (that is, the distance between each point is 100 m), the point marks 331, 332, and 333 representing the respective points are displayed in proximity on the route line 301F. In such a case, the connection lines 341, 342, and 343 are displayed so that the correspondence between the point marks 331, 332, and 333 and the point information notations 311, 312, and 313 is clear. At this time, the connection lines 342 and 343 may be displayed obliquely.

[0056] [3.5. Modification Example 5] In the above embodiment, as shown in FIG. 3(F), the connection lines 341 and 342 connecting the point marks 331 and 332 and the point information notations 311 and 312 in the simple route image 300F are respectively displayed. Instead, the display forms of the point marks displayed on the route line 301F may be made different from each other, and the display form of each point mark may be displayed in association with the point information notation. For example, as shown in FIG. 8, the point mark 331 indicating the point 321 indicated by the point information notation 311 is displayed in the form of a white circle, the point mark 332A indicating the point 322 indicated by the point information notation 312 is displayed in the form of a white triangle, a mark 311A having the form of a white circle is displayed in the point information notation 311, and a mark 312A having the form of a white triangle is displayed in the point information notation 312. Thereby, the correspondence between the point mark 331 and the point information notation 311 and the correspondence between the point mark 332 and the point information notation 312 can be clarified.

[0057] [3.6. Modification Example 6] As shown in FIG. 9, the route line 301F displayed on the simple route image 300F may be thickened and displayed in a bar shape. When the route line 301F is thickened, a mark can be displayed inside the line, so it is also possible to display a mark that clarifies the correspondence between the point and the point information notation. For example, a point mark 331B indicating a point 321 where information is denoted by a point information notation 311 is displayed in a display form of "circle 1", and a point mark 332B indicating a point 322 where information is denoted by a point information notation 312 is displayed in a display form of "circle 2". A mark 311B having a display form of "circle 1" is displayed in the point information notation 311, and a mark 312B having a display form of "circle 2" is displayed in the point information notation 312. Thereby, the correspondence between the point mark 331B and the point information notation 311 and the correspondence between the point mark 332B and the point information notation 312B can be clarified.

[0058] [3.7. Modification Example 7] In the above embodiment, as shown in FIG. 3(F), the route line 301F displayed on the simple route image 300F is a straight line. However, as shown in FIG. 10, the route line 301F may be curved. In this way, by displaying the route line 301F along the lower part and the right part of the simple route image 300F, more point information notations 311, 312, 313, 314, 315 than in the example of FIG. 3(F) can be displayed.

[0059] [3.8. Modification Example 8] In the above embodiment, intersections and points where route changes are made are given as examples of points where information related to the point information notation is displayed. However, the point may be a point where there is a facility such as a store that is a place of passage.

[0060] [3.9. Modification Example 9] In the above embodiment, as shown in FIG. 3(A), when displaying information related to an intersection as the point information notation 311, the traveling direction, the distance, and the intersection name are displayed. However, it is also possible to display only the traveling direction, or to further add and display information related to the lane.
