Description

  The present invention relates to a technique for displaying vehicle information and the like on a display device prepared in a vehicle compartment so that the user can easily understand the vehicle information.

  There is a wide variety of information provided in vehicle interiors. For example, the vehicle speed indicating the state of the vehicle, the engine speed, the shift position, the fuel, the water temperature and the like can be mentioned. Also, for example, a map for navigation, air conditioner setting information, audio information, and the like can be given. In recent years, night views for driving assistance and information on portable terminals brought into vehicles have been provided.

  Various display devices for providing such information are mounted, and examples thereof include a head-up display and a liquid crystal display on which a map for navigation is displayed. Some meter panels displaying vehicle speed and the like can provide various kinds of information by adopting liquid crystal or the like, and can be said to be a kind of display device.

  Since the amount of information (hereinafter referred to as “content”) provided in this way has increased, and since a plurality of display devices are mounted, which content and which region of which display device (hereinafter referred to as “area”). ) Is important.

  Conventionally, a technique for allocating a plurality of screen data generated by a mobile terminal to one display has been disclosed (see, for example, Patent Document 1). In this technique, priorities are assigned to screen data and display areas, respectively, and areas are determined in order of priority.

  However, in the prior art, when the content size is larger than the area size, the content is generally displayed in a reduced size. Therefore, there is a possibility that the display is difficult to see.

  In addition, since the area is fixedly set, if the size of the content is reduced, a margin portion is increased on the display device. In addition, since the area is fixedly set, a highly flexible layout cannot be realized.

  The present invention has been made in order to solve the above-described problems. The purpose of the present invention is to increase the degree of freedom of content layout by devising the area setting and to display information that is easy for the user to grasp. An object of the present invention is to provide a display control device that can perform the above-described operation.

In order to achieve the above object, the display control apparatus of the present invention assigns and displays content to be displayed to a plurality of areas set as display areas on the screen of a display device mounted on a vehicle. To do.

The display control apparatus of the present invention includes a content management unit, an area management unit, a content allocation control unit, and a display layout control unit.
The content management unit manages the content by associating the content size, which is the size required for information display. The content size is defined by the number of vertical and horizontal pixels, for example.

  The area management unit manages the area in association with the maximum size of the area on the assumption that the area can be enlarged and reduced. The maximum size is also defined by the number of vertical and horizontal pixels, for example.

  The content allocation control unit determines that content can be allocated to an area when the content size is equal to or smaller than the maximum size. The comparison between the content size and the maximum size is performed, for example, in both vertical and horizontal directions. Note that if the content always falls within the area for one of the vertical and horizontal directions, only the other may be compared.

When displaying the content assigned to the area, the display layout control unit displays the area enlarged or reduced according to the content size.
Conventionally, since the area is fixedly set, it is necessary to reduce and display the content when placing a larger content. Also, since the area is fixedly set, if a smaller content is to be arranged, the margin of the area becomes large.

  On the other hand, in the present invention, the area has the attribute of the maximum size, and the area is enlarged or reduced in accordance with the content. That is, the area is enlarged when a large size content is arranged, and the area is reduced when a small size content is arranged. In this way, the degree of freedom of content layout is increased, and information display that is easy for the user to grasp can be performed.

  By the way, when two contents are arranged side by side, if the area is enlarged to fit one content, the area is reduced to fit the other content, so that different sizes of contents can be arranged in a balanced manner.

Accordingly, et rear management unit, a predetermined area, as well as a manageable as a single area, also can be managed as a plurality of areas obtained by dividing the area, the position is a plurality of areas in the lower layer of the single area It is conceivable to adopt a configuration having a hierarchical data structure. In this case, the content allocation control unit, when allocating content to an area based on the hierarchical data structure, if the total size of the areas in the same hierarchy does not exceed the maximum size of the area in the upper hierarchy, the content It is determined that allocation to the area is possible. In this way, the effect of increasing the degree of freedom of content layout is remarkable. Also, it is possible to appropriately allocate content to an area having a hierarchical data structure.

In the above arrangement, it had been managed in association with the maximum size of the area to the area, et rear management unit further may be configured to manage the area in association with the default size of the area. In this case, the display layout control unit displays the content allocated to the area without reducing the area below the default size.

  That is, the area in which the default size is set is not reduced any further, and thus occupies a predetermined place in the display device. In this way, by setting the default size, the content can be placed at a fixed location.

Note that when the display layout is determined only by the size of the content and the area, content that is not so important may be placed in an inappropriate area.
Therefore, co intents management unit further manages content by associating the information value indicating the importance of the information, the area management unit further manages areas by associating the area value indicating where importance You may make it do. In this case, the content allocation control unit further allocates content to the area based on the information value and the region value.

  The content management unit manages the content in association with the information value indicating the importance of the information. For example, if the content is highly urgent, the information value becomes relatively large.

  In addition, the area management unit manages the area by associating the region value indicating the place importance. For example, an area where the movement of the line of sight during travel, such as a head-up display, is relatively high in area value.

  Then, the content allocation control unit allocates the content to the area based on the information value and the region value. For example, the area value of the area is used as a reference, and the information value of the content is assigned when it exceeds the area value. Further, for example, an evaluation value is calculated from the information value and the region value, and content is allocated to the area so that the evaluation value becomes large.

In this way, the content is allocated to the area according to the balance between the information value and the region value, so that it is possible to display information that is easy for the user to grasp.
Note that the content described above, by co intents management unit is considered to be acquired through a network in a vehicle. The present invention may be obtainable consists newly connected external device. Examples of the external device include a mobile phone such as a smartphone and an information terminal called a PDA. That is, if the information value is managed in association with the content, the content can be allocated to the area with the same algorithm regardless of the type of content.

Similarly, if an area value is managed in association with an area, content can be assigned to the area with the same algorithm regardless of the type of display device. Accordingly, et rear management unit is considered to manage areas to a plurality of display devices. In this case, et rear management unit, when a part of the display device is detachable, it is possible to update the area managed. For example, if the display device has area information, the area to be managed is updated with information from the attached / detached display device.

It is a flowchart which shows the area exclusion process in a display control process. It is explanatory drawing for demonstrating an area exclusion process concretely. It is explanatory drawing which shows arrangement | positioning of content. It is explanatory drawing which shows arrangement | positioning of content when default size is set.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram illustrating a schematic configuration of a display control apparatus 1 according to the embodiment.
The display control device 1 is configured around a control unit 10. Three display devices 21, 22, and 23 and an input / output IF 30 are connected to the control unit 10. Hereinafter, in order to distinguish the three display devices 21 to 23, they are described as “A display device 21”, “B display device 22”, and “C display device 23” as necessary.

  Each of the three A to C display devices 21 to 23 is embodied as, for example, a head-up display, a meter panel, a liquid crystal display device for displaying a map for navigation, or the like. However, the present invention is not limited to this.

  The input / output IF 30 is configured to be connected to a network (for example, CAN) in the vehicle, and the display control device 1 is connected to the multimedia ECU 41, the vehicle speed ECU 42, the engine speed sensor 43, various ECUs 44 via the input / output IF 30. And it is connected to various sensors 45. The various ECUs 44 include, for example, a navigation ECU. The various sensors 45 include an outside air temperature sensor that detects the temperature outside the passenger compartment, a water temperature sensor that detects the temperature of engine cooling water, and the like.

  With such a configuration, the display control device 1 can acquire various contents via a network. The content is acquired from “audio information” acquired from the multimedia ECU 41, “vehicle speed” acquired from the vehicle speed ECU 42, “engine speed” acquired from the engine speed sensor 43, and navigation ECUs included in the various ECUs 44. Various “maps”, “outside temperature” acquired from outside temperature sensors included in various sensors 45, and the like.

The control unit 10 includes a content management unit 11, an area management unit 12, an allocation management unit 13, a content allocation control unit 14, and a display layout control unit 15.
The content management unit 11 has a function for managing the above-described various contents, and similarly manages content in different categories. As shown in FIG. 2A, the content management unit 11 manages three attributes of “information value”, “content size”, and “display state” in association with each other.

  Here, information value indicates the importance of content. The value of information generally increases as urgent content such as “warning information”, followed by “vehicle speed” and “engine speed”, which are content related to the running state. Content such as “map” and “audio information” for navigation has a relatively low information value.

The content size is the size of an area required for content display, and is indicated by the number of vertical and horizontal pixels, for example.
Furthermore, the display state is information indicating whether or not the content is a display target, and is set to either “active state” indicating that it is a display target or “inactive state” indicating that it is not a display target. Is done.

  Specifically, it is conceivable that the “active state” and the “inactive state” can be switched according to the vehicle situation and user operation. For example, when the shift range is R, the content of “back monitor” is “active”, and when the shift range is other than R, the content of “back monitor” is “inactive”. Further, for example, when the user turns on the audio switch, the content of “audio information” becomes “active”, and when the user turns off the audio switch, the content of “audio information” becomes “inactive”.

  The area management unit 12 has a function for managing a plurality of areas as display areas. The area is set for the screens of the three display devices 21 to 23 of A to C. The area management unit 12 similarly manages the areas of the three display devices 21 to 23 of A to C. That is, the area of the A display device 21 and the area of the B display device 22 are managed without distinction. However, as shown in FIG. 2A, the area management unit 12 manages the three attributes “area value”, “default size”, and “maximum size” in association with each other.

  Here, the area value indicates the importance of the area. This area value is generally set higher for an area with better visibility. For example, an area of a head-up display that uses a windshield has a higher area value.

  The default size is the default size of the area, and is indicated by, for example, the number of vertical and horizontal pixels as with the content size. On the other hand, the maximum size is the maximum size of the area, which is also indicated by the number of vertical and horizontal pixels, for example.

That is, in the present embodiment, the area size is given a width within a certain range. As a result, the area is enlarged or reduced in accordance with the content.
Even if the content size is reduced, the area does not become smaller than the default size. Thereby, the area for the default size can be secured in the display device regardless of the content size. As a result, the area can be fixedly used as will be described later. Further, the default size may be set as “0”.

  The area management unit 12 manages the areas of the display devices 21 to 23 of A to C in a hierarchical data structure. For example, an area of the A display device 21 is described as an example as shown in FIG.

  As shown in FIG. 3A, the display area of the A display device 21 includes an a area that uses the entire screen, a b area and a c area obtained by dividing the a area into two left and right, and further, the b area is divided into two It is assumed that the d area and the e area divided into two, and the f area and the g area obtained by dividing the c area into two upper and lower parts are set.

  At this time, as shown in FIG. 3B, the area a is managed as the area of the highest hierarchy. The areas b and c are managed in the hierarchy immediately below the area a, and the areas d and e and the areas f and g are managed in the hierarchy immediately below the areas b and c, respectively.

As a result, as shown in FIG. 3C, for example, when content is allocated to the area b, it is determined that the areas d and e that are lower than the area b cannot be used.
In the present embodiment, by having the content management unit 11 and the area management unit 12 as described above, the content allocation control unit 14 compares the information value of the content with the area value of the area, and in principle, the information value of the content Content is allocated to an area only if is greater than the area value of the area. Hereinafter, the information value and the area value are collectively referred to as “value”, and the content size, the default size of the area, and the maximum size are collectively referred to as “size”.

  The content allocation control unit 14 allocates content to an area in consideration of “size” in addition to “value” of the content and the area. When the content is allocated to the area, the display layout control unit 15 displays the content by enlarging and reducing the area in accordance with the content.

  By the way, the process of allocating content to an area based on such content and area attributes can be said to be a “dynamic allocation” process. Apart from this, some content is assigned to a predetermined area. This is the so-called “static allocation”. The allocation management unit 13 manages the correspondence between the predetermined content and the area.

  As shown in FIG. 2B, the allocation management unit 13 has a correspondence relationship between, for example, the X content, the A area, and the B area. At this time, the X content is allocated to the A area or the B area. For example, there is a correspondence between the Y content and the C area. At this time, the Y content is assigned to the C area.

  Next, processing for display control will be described more specifically. FIG. 4 is a flowchart showing the display control process. This display control process is repeatedly executed while the ignition key is on.

  In the first S100, value change processing is executed. This processing is to change the information value of the content and the area value of the area based on the vehicle status (in this embodiment, whether the vehicle is traveling or stopped). In the present embodiment, the value change process is executed. However, since this process is not essential, the value change process may be omitted as another form. Moreover, it is good also as a structure performed only when predetermined conditions are satisfied.

  In the next S110, a content list is created. In this process, the content whose display state as the attribute is “active state” is extracted and rearranged in descending order of information value. This process is realized as a function of the content management unit 11. Here, it is assumed that N pieces of content are rearranged.

  In the next S120, the variable n indicating the content is initialized as “1”. Each time this variable n is incremented, the first content → second content → third content →... Is processed.

In subsequent S130, an area is searched. This process searches for all areas that have not yet been assigned content.
In the next S140, the area is excluded based on the hierarchical data structure. In this process, even if an area is not assigned content, if the content is assigned to an area located higher in the hierarchical data structure, the area is excluded. For example, as shown in FIG. 3C, when content is assigned to the area b, the areas d and e are excluded.

  In subsequent S150, the area is excluded based on the allocation management. Specifically, based on the correspondence stored in the allocation management unit 13, areas that do not have a correspondence between content and area are excluded.

  In next S160, an area exclusion process is performed. This process excludes the area based on the content size and the maximum size of the area. FIG. 5 is a flowchart showing the area exclusion process.

  In the first S161, it is determined whether or not the content is equal to or smaller than the maximum size of the area. If it is determined that the content is equal to or smaller than the maximum size of the area (S161: YES), the process proceeds to S162. On the other hand, if the content exceeds the maximum size of the area (S161: NO), the area is excluded in S164, and then the area exclusion process ends.

  In S162, it is determined whether or not a parent area exists. This process is to determine whether or not there is an area that is one layer above the area to be allocated. If it is determined that there is a parent area (S162: YES), the process proceeds to S163. On the other hand, if it is determined that there is no parent area (S162: NO), the area exclusion process is terminated.

  In S163, it is determined whether or not the size is equal to or smaller than the maximum size of the parent area. This process determines whether or not the total size of the child areas including the target area is equal to or less than the maximum size of the upper layer area. If it is determined that the size is equal to or smaller than the maximum size of the parent area (S163: YES), the processing from S162 is repeated. As a result, a determination is further made regarding the upper layer area. On the other hand, if the maximum size of the parent area is exceeded (S163: NO), the area to be allocated is excluded in S164, and then the area exclusion process is terminated.

  In order to facilitate understanding of the area exclusion process, a specific example will be described here. In the following example, the size of the area in the horizontal direction will be described so as not to complicate the description. The same applies to the vertical size.

  As shown in FIG. 6, a case where content is assigned to the area b is considered. At this time, first, it is determined whether or not the content is equal to or smaller than the maximum size of the b area (S161 in FIG. 5). If the size is equal to or smaller than the maximum size of area b (S161: YES), it is then determined whether or not there is a parent area (S162). In the example of FIG. 6, since the a area exists in the upper hierarchy of the b area, an affirmative determination is made here. Subsequently, it is determined whether or not the total size of the child area is equal to or smaller than the maximum size of the parent area (S163). At this time, as shown in FIG. 6A, when the total size of the b area and the c area which are child areas is equal to or smaller than the maximum size of the parent area which is the a area (S163: YES), content allocation The area b is a candidate for the area. On the other hand, as shown in FIG. 6B, when the total size of the b area and the c area that are child areas exceeds the maximum size of the parent area that is the a area (S163: NO), the b area is excluded. (S164).

  Note that the processing from S162 is repeated when an affirmative determination is made in S163, as shown in FIG. 6 (c), when allocation to a lower-layer d area is considered, as shown in FIG. This is for determining not only the relationship but also the relationship with the a area in the higher hierarchy. Specifically, it is determined whether or not the total size of the d area and the e area (grandchild area) is equal to or smaller than the maximum size of the b area (child area) (S163), and then there is an upper layer of the b area. Whether or not the total size of the b area and the c area (child area) is equal to or smaller than the maximum size of the a area (parent area) is determined (S163). In other words, when an area in a lower hierarchy is targeted, it is repeatedly determined whether or not the area is within the area of the next higher hierarchy.

  Returning to FIG. 4, in S170, content is allocated to the area. In this process, content is allocated to an area that is lower than the information value of the content and has the largest area value among the areas that have been processed up to S160.

  In subsequent S180, it is determined whether or not the variable n is equal to the number N of contents. This process determines whether or not all the content has been processed. If n = N (S180: YES), the process proceeds to S190. On the other hand, if n ≠ N (S180: NO), that is, while there is unprocessed content, the variable n is incremented in S200, and the processing from S130 is repeated.

  In S190, the content is displayed. This process displays content in the allocated area. Specifically, the area is enlarged and displayed in accordance with the content size which is the content attribute. This will be described with reference to FIGS. 7 and 8 show that the hatched portion is content.

  For example, consider the case where child areas b and c are set in the parent area a as shown in FIG. At this time, the maximum sizes of the child areas b and c are both the same as the maximum size of the parent area a, and the default sizes of the child areas b and c are both “0”.

  At this time, when content having a relatively large content size is allocated to the child area b, as shown in FIG. 7B, the child area b is enlarged and the child area c is reduced in size. It is displayed. When content having the same size as the parent area a is arranged for the child area b, the child area c is not displayed as shown in FIG.

  On the other hand, when content having a relatively large content size is allocated to the child area c, as shown in FIG. 7C, the child area c is enlarged and the child area b is reduced in size. It is a condition that it is done. When content having the same size as the parent area a is arranged for the child area c, the child area b is not displayed as shown in FIG.

  Further, for example, in the example of FIG. 3A, the maximum size of the child area b is the same as the maximum size of the parent area a, and the default size of the child area b is as shown in FIG. Suppose there is. On the other hand, it is assumed that the default size of the child area c is “0”.

  At this time, since the location of the child area b is secured even if no content is allocated to the child area b, the content allocated to the child area c is allocated including the case where no content is allocated to the child area b. When the received content is smaller than the default size, it is displayed at the same place (see FIGS. 8A to 8C). Further, when content having the same size as the parent area a is arranged for the child area b, the child area c is not displayed as shown in FIG.

Next, the effect which the display control apparatus 1 of this embodiment exhibits is demonstrated.
In the present embodiment, the content management unit 11 manages the content size, which is the size of the area required for content display, in association with the content. On the other hand, the area management unit 12 manages the maximum size and default size of the area in association with the area. At this time, in the area exclusion process, it is determined whether or not the content size is equal to or smaller than the maximum size of the area (S161 in FIG. 5). If the content size exceeds the maximum size of the area (S161: NO), Areas are excluded from allocation. Thereafter, the display layout control unit 15 displays the area enlarged or reduced in accordance with the content size (S190).

  Conventionally, since the area is fixedly set, it is necessary to reduce and display the content when placing a larger content. Also, since the area is fixedly set, if a smaller content is to be arranged, the margin of the area becomes large.

  In contrast, in the present embodiment, “maximum size” is set as the area attribute so that the area size dynamically changes in accordance with the content size (see FIG. 7). That is, the area is enlarged when a large size content is arranged, and the area is reduced when a small size content is arranged. As a result, the degree of freedom of content layout is increased, and information display that is easy for the user to grasp can be performed.

  In the present embodiment, the area management unit 12 has the hierarchical data structure of the area shown in FIG. Then, in the area exclusion process, it is determined whether or not the parent area exists (S162 in FIG. 5). If the parent area exists (S162: YES), the total size of the child areas is the maximum size of the parent area. If it exceeds (S163: NO), the area is excluded (S164). Such determination is repeated until the area of the highest hierarchy is reached (S162: NO) (S163: YES, S162). As a result, the effect of increasing the degree of freedom of content layout is remarkable. Also, it is possible to appropriately allocate content to an area having a hierarchical data structure.

  Furthermore, in the present embodiment, the area management unit 12 manages the default size of the area in association with each area. Further, the display layout control unit 15 displays content in consideration of the default size. Specifically, as shown in FIGS. 8A to 8C, when the content size is smaller than the default size of the area b including the case where the content is not arranged, the location of the area b is set with the default size. Secure. Thereby, the specific content allocated to the area c can be displayed at the same place.

  In the present embodiment, the area value of the area is compared with the information value of the content, and if the information value exceeds the area value, the content is allocated to the area (S180 in FIG. 4). Thereby, since content is allocated to an area by the balance between information value and region value, information display that is easy for the user to grasp can be performed.

  Furthermore, in this embodiment, various content is acquired via the network in a vehicle (refer FIG. 1). At this time, the content management unit 11 similarly manages various contents in association with “information value”, “content size”, and “display state”. As a result, content can be allocated to an area with the same algorithm regardless of the type of content.

  Similarly, in this embodiment, “area value”, “default size”, and “maximum size” are associated with a plurality of areas of the display devices 21 to 23 of A to C, and the areas are managed. Thereby, even if the display devices 21 to 23 are different, it is possible to determine an area to which content should be allocated by the same algorithm.

As mentioned above, this invention is not limited to embodiment mentioned above at all, In the range which does not deviate from the summary, it can implement with a various form.
(B) For example, by managing content and area only by their attributes, it is possible to assign content to the area with the same algorithm regardless of the type of content and regardless of the distinction between the display devices 21 to 23. I have already mentioned that.

  Therefore, in the display control device 1 of the above-described embodiment, for example, when any of the display devices 21 to 23 of A to C fails, the area management unit 12 changes the algorithm by updating the management information. And content can be allocated to the area.

  Similarly, as shown in FIG. 1, it is easy to add and connect a D display device 50. Also in this case, the area management unit 12 may update the management information according to the D display device 50. Examples of the D display device 50 include a mobile phone such as a smartphone and an information terminal called a PDA. At this time, it is conceivable to acquire information related to the area from the D display device 50 itself. It is also conceivable that the content management unit 11 acquires content from the D display device 50.

  (B) In the above embodiment, the information value and the region value are changed based on whether the vehicle is running or not. However, the value is changed according to more detailed driving situations such as low speed driving and high speed driving. The value may be changed, or may be used together with a system capable of calculating the driver's load, for example, and the value may be changed in consideration of the driver's load.

  (C) In the above embodiment, in order from the content having the higher information value, the area having the region value lower than the information value is assigned to the area having the highest region value (S170 in FIG. 4).

  On the other hand, for example, it may be considered to allocate content to an area having the second or later area value. In this way, when a highly urgent content is in an “active state”, an area with a high area value is vacant, so that the area can be quickly displayed using the area. .

  Further, an evaluation value may be calculated from the information value and the region value, and a combination of a content and an area having a high evaluation value may be adopted. For example, the evaluation value may be obtained by weighting and adding the information value and the region value.

  The display devices 21 to 23 in the above embodiment correspond to “display devices”, the display control device 1 corresponds to “display control devices”, the content management unit 11 corresponds to “content management units”, and area management. The unit 12 corresponds to an “area management unit”, the content allocation control unit 14 corresponds to a “content allocation control unit”, and the display layout control unit 15 corresponds to a “display layout control unit”.

  Also, the processing of S100 and S110 in FIG. 4 corresponds to the processing as the function of the “content management unit”, the processing of S120 to S180 corresponds to the processing as the function of the “content allocation control unit”, and the processing of S190 Corresponds to processing as a function of the “display layout control unit”.
