Description

  The present invention relates to an in-vehicle display control device and an in-vehicle display control method, and is particularly suitable for use in an apparatus and method for controlling display of information on an in-vehicle display provided on an instrument panel of a vehicle.

  Conventionally, there is a vehicle in which an instrument panel (hereinafter referred to as an instrument panel) assembled on a dashboard is configured by a liquid crystal display device. On-vehicle display (hereinafter referred to as instrument panel display) provided in the instrument panel displays meter information necessary for traveling of the vehicle such as traveling speed, engine speed, and remaining amount of fuel. There is also a vehicle in which information related to a navigation device and an audio device is displayed on an instrument panel display.

  In general, meter information is essential information for the driver. Therefore, according to the indicated position of the pointer, the vehicle information (such as a warning display image) different from the pointer expressed by the meter information can be effectively transmitted to the driver without reducing the visibility of the meter information. There has been proposed a vehicle display device that changes the display position of an alarm display image (see, for example, Patent Document 1).

  In addition, the meter information essential for the driver is usually displayed large in the instrument panel display so that the driver can easily see it. Therefore, there is a problem that an area for displaying information other than meter information (hereinafter referred to as “other information”) is narrowed, and the visibility of other information is deteriorated. In response to such a problem, the present applicant determines the non-use speed area of the speedometer based on the traveling state of the vehicle, and enlarges and displays other information up to the determined non-use speed area. A patent application was filed for this technology (see, for example, Patent Document 2).

JP 2012-228773 A Japanese Patent Application No. 2012-237969

  However, in the technique described in Patent Document 1, the display position of the alarm display image changes at any time according to the position of the pointer of the speedometer, so the display position is hardly determined. If the content of the information displayed avoiding the pointer is always fixed and does not change like the alarm display image described in Patent Document 1, it is relatively easy to recognize what is displayed there. Therefore, there is no big problem even if the display position changes frequently. However, in the case of an image whose display contents change every moment, such as a navigation image, for example, if the display position changes frequently, there is a problem that it becomes difficult to grasp the contents.

  On the other hand, in the technique described in Patent Document 2, other information other than the speedometer is enlarged or reduced according to the position of the pointer. If other information that is displayed avoiding the pointer is a navigation image, if it is enlarged or reduced according to the position of the pointer, it may be difficult to grasp the sense of distance from the map or it may be difficult to grasp the vehicle position. The problem arises.

  The present invention has been made to solve such a problem, and aims to enable easy-to-understand display of other information whose content changes every moment without impairing the visibility of meter information. To do.

In order to solve the above-described problems, in the present invention, one configuration of meter information in an overlapping display area in which a first display area for displaying meter information and a second display area for displaying other information overlap. Others allocated to the entire second display area without identifying the unused area where the instruction information as an element is not displayed and expanding the size of the other information itself for the identified unused area The information of the portion allocated to the unused area in the overlapping display area is displayed.

  According to the present invention configured as described above, other information is displayed instead of the meter information for the unused area in which the instruction information that is one component of the meter information is not displayed. The amount of information displayed for the information of increases. Since the other information displayed in the unused area at this time is a part of the information originally assigned to the unused area of the overlapping display area in order to display other information, the display position is determined in advance. It is a position, and information is not enlarged and displayed. That is, other information is displayed at a predetermined position with a normal size and an increased amount of information. On the other hand, regarding the meter information, the instruction information is displayed as usual in an area other than the unused area. Thereby, other information can be displayed in an easy-to-understand manner without impairing the visibility of meter information.

  In the present embodiment, a navigation image is displayed on the instrument panel display 20 as an example of other information. The navigation image is displayed in the second display area 22 provided on the instrument panel display 20. The second display area 22 is provided between the left and right first display areas 21a and 21b, and overlapped display areas 23a and 23b (shaded portions) partially overlapping the left and right first display areas 21a and 21b. have.

  In the overlap display areas 23a and 23b, either a pointer-type meter image or a navigation image is displayed according to vehicle information such as travel speed and engine rotation speed. On the other hand, in the second display area 22, an area other than the overlapping display areas 23a and 23b (a central area other than the shaded area) is a dedicated display area 24 in which navigation images are always displayed.

  As shown in FIG. 1, the in-vehicle display control device 10 of the present embodiment includes a vehicle information input unit 1, a navigation information input unit 2, a display control unit 3, and a nonuse area specifying unit 4 as its functional configuration. Has been. In addition, an instrument panel display 20, a vehicle speed sensor 30, a rotation speed sensor 40, and a navigation device 50 are connected to the in-vehicle display control device 10 of the present embodiment.

  Note that the functional blocks of the vehicle information input unit 1, the navigation information input unit 2, the display control unit 3, and the non-use area specifying unit 4 are realized by any of a hardware configuration, a DSP (Digital Signal Processor), and software. Is possible. For example, when realized by software, each of the functional blocks 1 to 4 is actually configured to include a computer CPU or MPU, RAM, ROM, etc., and stored in a recording medium such as RAM, ROM, hard disk, semiconductor memory, or the like. It can be realized by running the program.

  The vehicle information input unit 1 inputs travel speed information from the vehicle speed sensor 30 and supplies it to the display control unit 3 and the nonuse area specifying unit 4. Further, the vehicle information input unit 1 inputs engine rotation speed information from the rotation speed sensor 40 and supplies it to the display control unit 3 and the non-use area specifying unit 4. The navigation information input unit 2 inputs a navigation image from the navigation device 50 and supplies it to the display control unit 3.

  The display control unit 3 generates a speedometer image based on the traveling speed information input from the vehicle information input unit 1 and displays it on the instrument panel display 20. The speedometer image is image information imitating a physical speedometer. In the present embodiment, a circular speedometer is used to draw numbers and scales indicating a plurality of speeds along the circumference as indices, and a pointer is set at a position corresponding to the travel speed information input from the vehicle information input unit 1. Is displayed in the first display area 21 a on the right side of the instrument panel display 20.

  Further, the display control unit 3 generates a tachometer image based on the engine rotation speed information input from the vehicle information input unit 1 and causes the instrument panel display 20 to display the tachometer image. The tachometer image is image information imitating a physical tachometer. In the present embodiment, a circular tachometer is used to draw a number and scale indicating a plurality of engine rotation speeds as an index along the circumference, and a position corresponding to the engine rotation speed information input from the vehicle information input unit 1 A tachometer image formed by drawing a pointer is displayed in the first display area 21b on the left side of the instrument panel display 20.

  In addition, the display control unit 3 displays the navigation image input from the navigation information input unit 2 in the second display area 22 of the instrument panel display 20 as other information other than meter information.

  The display control unit 3 displays the right overlapping display area 23a in which the first display area 21a and the second display area 22 on the right overlap with each other according to the traveling speed information input from the vehicle information input unit 1. Either a speedometer image or a navigation image is displayed. In addition, the display control unit 3 responds to the engine speed information input from the vehicle information input unit 1 in the left overlapping display area 23b where the left first display area 21b and the second display area 22 overlap. Thus, either the tachometer image or the navigation image is displayed.

  Here, the display control unit 3 may synthesize and display the meter image and the navigation image on one layer, or divide and display the meter image and the navigation image in two layers. You may do it. In the latter case, for example, the navigation image is displayed on the lower layer, and the meter image is displayed on the upper layer. In this case, the portion of the upper layer where the meter image is not displayed is transparent so that the navigation image of the lower layer can be seen through the upper layer. Further, instead of dividing the layer into two by one display, it is also possible to use a display device having a two-layer structure.

  The unused area specifying unit 4 specifies an unused area in the overlapping display areas 23a and 23b where the hands of the speedometer and the tachometer are not displayed. In the present embodiment, the unused area specifying unit 4 specifies an area on the left or right side of the pointer display position as an unused area.

  FIG. 3 is a diagram for explaining the unused areas 25a and 25b. As shown in FIG. 3A, when the dedicated display area 24 for the navigation image exists on the left side of the overlapping display area 23a, that is, the right side where the first display area 21a on the right side and the second display area 22 overlap. In the overlapping display area 23a, the non-use area specifying unit 4 displays an area on the left side of the display position of the pointer 26 determined according to the traveling speed information input from the vehicle information input unit 1 (the hatched part surrounded by a dotted line). The unused area 25a is specified.

  Here, as shown in FIG. 3A, when the pointer 26 points in any direction of the left half of the first display area 21 a on the right side, the unused area specifying unit 4 The area on the left side of the display position at the tip is specified as the unused area 25a. On the other hand, when the pointer 26 points in any direction of the right half of the first display area 21a on the right side, the non-use area specifying unit 4 selects the area on the left side from the root display position of the pointer 26. The unused area 25a is specified.

  Similarly, as shown in FIG. 3B, when the dedicated display area 24 for the navigation image exists on the right side of the overlapping display area 23b, that is, the first display area 21b and the second display area 22 on the left side. In the overlapping display area 23b on the left side where the two overlap, the unused area specifying unit 4 specifies the area on the right side of the display position of the pointer 26 (the hatched part surrounded by the dotted line) as the unused area 25b.

  Here, as shown in FIG. 3B, when the pointer 26 points in any direction of the right half of the left first display area 21b, the non-use area specifying unit 4 The area on the right side of the display position of the tip is specified as the unused area 25b. On the other hand, when the pointer 26 points in any direction of the left half of the first display area 21b on the left side, the unused area specifying unit 4 selects the area on the right side of the display position of the root of the pointer 26. The unused area 25b is specified.

  In the present embodiment, the speedometer image is displayed in the first display area 21a on the right side and the tachometer image is displayed in the first display area 21b on the left side, but this may be reversed. In this case, the non-use area specifying unit 4 specifies the area on the left side of the display position of the pointer 26 determined according to the engine rotation speed information input from the vehicle information input unit 1 as the non-use area 25a, and the traveling speed. The area on the right side of the display position of the pointer 26 determined according to the information is specified as the unused area 25b.

  The display control unit 3 includes, among the navigation images assigned to the entire second display area 22 for the non-use areas 25a and 25b specified by the non-use area specifying unit 4, among the overlapping display areas 23a and 23b. Control is performed so that the image of the portion allocated to the unused areas 25a and 25b is displayed instead of the meter image. In addition, the display control unit 3 applies the entire first display areas 21a and 21b to the areas other than the unused areas 25a and 25b specified by the unused area specifying unit 4 in the overlapping display areas 23a and 23b. Of the allocated meter images, control is performed to display the image of the portion allocated to the areas other than the unused areas 25a and 25b in the overlapping display areas 23a and 23b.

  FIG. 4 is a diagram illustrating an example of a navigation image displayed in a part of the dedicated display area 24 and the unused area 25a on the right side. FIG. 4A shows a state where the vehicle is traveling at a relatively high speed and the unused area 25a on the left side of the pointer 26 is wide. On the other hand, FIG. 4B shows a state in which the vehicle is traveling at a relatively slow speed and the unused area 25a on the left side of the pointer 26 is narrow.

  Of the overlapping display area 23a, in the unused area 25a, the navigation image is subjected to a process of gradually decreasing the luminance toward the area other than the unused area 25a. Since the speedometer image is displayed in the first display area 21a on the right side following the area where the brightness of the navigation image is reduced, the speedometer is in an easy-to-see state. Further, the user does not feel uncomfortable that the navigation image is suddenly interrupted and displayed.

  FIG. 5 is a flowchart showing an operation example of the vehicle-mounted display control device 10 according to the present embodiment configured as described above. The flowchart shown in FIG. 5 starts when the accessory switch of the vehicle is turned on. First, the vehicle information input unit 1 inputs travel speed information and engine rotation speed information from the vehicle speed sensor 30 and the rotation speed sensor 40, respectively (step S1). The navigation information input unit 2 inputs a navigation image from the navigation device 50 (step S2).

  Next, the non-use area specifying unit 4 selects the speed in the overlapping display areas 23a and 23b of the instrument panel display 20 based on the traveling speed information and the engine speed information input from the vehicle information input unit 1 in step S1. The unused areas 25a and 25b in which the pointers of the meter and the tachometer are not displayed are specified (step S3).

  Subsequently, the display control unit 3 gradually reduces the luminance of a part of the navigation image of the portion displayed in the unused area 25a, 25b specified in step S3 in the overlapping display areas 23a, 23b. (Step S4). Then, the display control unit 3 displays the navigation image with the luminance partially reduced in this way in the second display area 22 of the instrument panel display 20 (step S5).

  The display control unit 3 also includes a part of the speedometer image and the tachometer image for the areas other than the unused areas 25a and 25b specified in step S3 in the first display areas 21a and 21b of the instrument panel display 20. Are displayed respectively (step S6). Thereafter, the in-vehicle display control device 10 determines whether or not the accessory switch is turned off (step S7). If not, the process returns to step S1. On the other hand, when the accessory switch is turned off, the process of the flowchart shown in FIG. 5 ends.

  As described above in detail, in the present embodiment, in the overlapping display areas 23a and 23b in which the first display areas 21a and 21b displaying the meter image and the second display area 22 displaying the navigation image overlap, The unused areas 25a and 25b in which the pointer of the meter image is not displayed are specified. Then, a part of the navigation image assigned to the entire second display area 22 (image corresponding to the non-use areas 25a and 25b) is displayed on the specified non-use areas 25a and 25b. ing.

  According to the present embodiment configured as described above, a part of the navigation image is displayed instead of the meter image for the unused areas 25a and 25b in which the pointer of the meter image is not displayed. The amount of information displayed about increases. At this time, the navigation images displayed in the unused areas 25a and 25b are part of the images assigned to the unused areas 25a and 25b in the overlapping display areas 23a and 23b in order to display the navigation images. Therefore, the display position is a predetermined position, and the navigation image is not enlarged and displayed. That is, the navigation image is displayed at a predetermined position with a normal size and an increased amount of information. On the other hand, with respect to the meter image, the pointer is displayed as usual in an area other than the unused areas 25a and 25b. Thereby, the navigation image can be displayed in an easy-to-understand manner without impairing the visibility of the meter image.

  In the above embodiment, the example in which the non-use area 25a is specified based on the traveling speed information detected by the vehicle speed sensor 30 has been described, but the present invention is not limited to this. For example, when a speedometer image is displayed in the first display area 21b on the left side, when the vehicle is traveling on a road whose speed limit is equal to or lower than a predetermined speed, the right side of the display position of the pointer indicating the predetermined speed May be specified as the unused area 25b.

  FIG. 6 is a block diagram illustrating a functional configuration example of the in-vehicle display control device 10 in this case. In the example illustrated in FIG. 6, a navigation information input unit 2 a and an unused area specifying unit 4 a are provided instead of the navigation information input unit 2 and the unused area specifying unit 4 illustrated in FIG. 2.

  The navigation information input unit 2a inputs information representing the speed limit of the road on which the vehicle is traveling from the navigation device 50 in addition to the navigation image. The navigation device 50 stores map data, and road link information in the map data includes road speed limit information. The navigation information input unit 2a inputs the speed limit information from the navigation device 50. The input of speed limit information is not limited to the example performed from the navigation device 50. For example, the speed limit of a running road may be detected by recognizing a road sign or road sign from an image around a vehicle photographed by a camera (not shown).

  Based on the speed limit information input by the navigation information input unit 2a, the non-use area specifying unit 4a specifies the area on the right side of the display position of the pointer indicating the speed limit as the non-use area 25b. For example, when the vehicle is traveling on a road with a speed limit of 40 km / h, the nonuse area specifying unit 4a specifies the area on the right side of the display position of the pointer indicating the speed of 40 km / h as the nonuse area 25b.

  Alternatively, when the speedometer image is displayed in the first display area 21a on the right side, when the vehicle is traveling on the highway, the area on the left side of the display position of the pointer indicating the predetermined speed is not used. You may make it identify as 25a. FIG. 7 is a block diagram illustrating a functional configuration example of the in-vehicle display control device 10 in this case. In the example illustrated in FIG. 7, a navigation information input unit 2 b and an unused area specifying unit 4 b are provided instead of the navigation information input unit 2 and the unused area specifying unit 4 illustrated in FIG. 2.

  The navigation information input unit 2b inputs information representing the road type of the road on which the vehicle is traveling from the navigation device 50 in addition to the navigation image. The navigation device 50 stores map data, and road type information is included in the road link information in the map data. The navigation information input unit 2 b inputs this road type information from the navigation device 50.

  When the road type information input by the navigation information input unit 2b indicates that it is a highway, the unused area specifying unit 4b uses a display position of a pointer indicating a predetermined speed (for example, 60 km / h). Also, the left area is specified as the unused area 25a. This is because it is assumed that the vehicle speed never falls below 60 km / h when the vehicle is traveling on a highway.

  Similarly, when the speedometer image is displayed in the first display area 21b on the left side, when the vehicle is traveling on a general road, the display position of the pointer indicating a predetermined speed (for example, 60 km / h) is used. Alternatively, the right area may be specified as the unused area 25b. The functional configuration example of the in-vehicle display control device 10 in this case is the same as that in FIG.

  When the road type information input by the navigation information input unit 2b indicates a general road, the non-use area specifying unit 4b uses a display position of a pointer indicating a predetermined speed (for example, 60 km / h). Also, the right area is specified as the unused area 25b. This is because the vehicle speed is assumed not to exceed 60 km / h when the vehicle is traveling on a general road.

  Alternatively, when the speedometer image is displayed in the first display area 21b on the left side, when the vehicle is traveling on a congested road, the area on the right side of the display position of the pointer indicating the predetermined speed is not displayed. The use area 25b may be specified. FIG. 8 is a block diagram illustrating a functional configuration example of the in-vehicle display control device 10 in this case. In the example shown in FIG. 8, a navigation information input unit 2 c and an unused region specifying unit 4 c are provided instead of the navigation information input unit 2 and the unused region specifying unit 4 shown in FIG. 2.

  The navigation information input unit 2c inputs traffic information on the road on which the vehicle is traveling from the navigation device 50 in addition to the navigation image. When the traffic jam information input by the navigation information input unit 2c indicates that the unused area specifying unit 4c is in a traffic jam, the non-use area specifying unit 4c uses a display position of a pointer indicating a predetermined speed (for example, 30 km / h). Also, the right area is specified as the unused area 25b. This is because it is assumed that the vehicle speed will not exceed 30 km / h when the vehicle is traveling on a congested road.

  Moreover, although the said embodiment demonstrated the example which displays a pointer type meter image on the instrument panel display 20 as an example of meter information, this invention is not limited to this. For example, the meter information may be an indicator-type meter image composed of an indicator as instruction information for changing the instruction position by expanding and contracting according to vehicle information, and an index that is an instruction target of the indicator.

  In this case, when the indicator expands and contracts to the left and right, the unused area specifying unit 4 specifies the area on the left or right side of the indicator display position as the unused area. On the other hand, when the indicator expands and contracts vertically, an area above or below the display position of the indicator is specified as the unused area.

  In addition, each of the above-described embodiments is merely an example of implementation in carrying out the present invention, and the technical scope of the present invention should not be construed in a limited manner. That is, the present invention can be implemented in various forms without departing from the gist or the main features thereof.
