- 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 various contents described above, and similarly manages content in different categories. As shown in FIG. 2A, the content management unit 11 stores three attributes (parameters) “information value”, “content size”, and “display state” in association with each other, as shown in FIG. Storage section).
- 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 the area required to display the content, and is represented by the number of vertical and horizontal pixels, for example.
- the display state is flag information indicating whether or not the content is a display target, and is either “active state” indicating that it is a display target or “inactive state” indicating that it is not a display target. Is set.
- each content can be switched between an “active state” and an “inactive state” according to the vehicle status and user operation.
- the shift range is R
- the content of the “back monitor” based on information captured by the rear view camera is “active”
- the shift range is other than R
- the content of the “back monitor” is “inactive”
- the content of “audio information” such as the audio control panel becomes “active”

- 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.
- the area management unit 12 of the present embodiment stores two attributes (parameters) “area value” and “area size” in association with each area.
- a device storage unit
- the domain 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 area size is the size of the area, and is indicated by vertical and horizontal pixels, for example, as with the content size.
- the area management unit 12 manages the areas of the display devices 21 to 23 of A to C in a hierarchical data structure.
- the area management unit 12 is a variable indicating the hierarchical structure relationship of each area. Is provided with a storage device (storage unit).
- the area of the A display device 21 will be described as an example.
- the display screen of the A display device 21 can provide display areas a to g.
- the inclusion relation of each area is referred to when a combination of content and area is extracted, and the area included in the already occupied area is excluded from the areas to which content is assigned.
- 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 a b area that is divided into two left and right. 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.
- 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.
- 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.
- information value and area value are collectively referred to as “value”
- content size and area size are collectively referred to as “size”.
- the content allocation control unit 14 allocates the content to the area in consideration of not only the “value” of the content and the area but also the “size”.
- the display layout control unit 15 displays the content in the area.
- the process of allocating content to an area based on such content and area attributes can be said to be a “dynamic allocation” process.
- 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.
- the allocation management unit 13 has, for example, a correspondence relationship between 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.
- FIG. 4 is a flowchart showing the display control process. This display control process is repeatedly executed while the ignition key is on.
- 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).
- a content list is created.
- the content whose display state as the attribute is “active state” is extracted and rearranged in descending order of information value.
- N pieces of content are rearranged.
- 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.
- the area is excluded based on 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.
- the area is excluded based on the content size and the area size. This process excludes an area having an area size smaller than the content size of the allocated content.
- the Z content as shown in FIG. 2C has a content size of “200 ⁇ 200”, when the Z content is allocated, the D area whose area size is “50 ⁇ 20” is excluded. Condition.
- 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.
- content is allocated to the area.
- 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. For example, in FIG. 2C, since the information value of the Z content is “20”, the Z content is allocated to the F area having the region value “10” lower than the information value “20”.
- FIG. 5 is a flowchart showing value change processing.
- the first S101 it is determined whether or not the vehicle is running. This determination is made based on, for example, “vehicle speed” sent from the vehicle speed ECU 42. If it is determined that the vehicle is traveling (S101: YES), the information value of the content is changed to the information value during traveling in S102, and the region value of the area is changed to the region value during traveling in S103. Then, the value change process is terminated. On the other hand, when it is determined that the vehicle is not traveling (S101: NO), that is, when the vehicle is stopped, the information value of the content is changed to the information value when the vehicle is stopped in S104, and the area value of the area is changed in S105. The value is changed to the area value while the vehicle is stopped, and then the value change process is terminated.
- vehicle speed sent from the vehicle speed ECU 42. If it is determined that the vehicle is traveling (S101: YES), the information value of the content is changed to the information value during traveling in S102, and the region value of the area is changed to the
- the information value during running / stopping for the content and the area value during running / stopping for the area are determined in advance.
- the content acquired from the multimedia ECU 41 is less important in terms of safety and the like while traveling than when the vehicle is stopped.
- the information value during traveling is set smaller than the information value during stopping.
- the importance of an area in which the movement of the line of sight is minimized during traveling increases. Therefore, for such an area, the area value during traveling is set larger than the area value during stopping.
- the area management unit 12 manages the areas of the display devices 21 to 23 of A to C in a hierarchical data structure.
- the area of the A display device 21 is shown to be hierarchized.
- the A display device 21 is a meter panel
- the area can be classified as shown in FIG. 12, for example.
- the meter panel has a central area indicated by symbol A, a left area indicated by symbol B, an upper right area indicated by symbol C, and the like.
- the central area is hierarchized and a plurality of contents can be allocated.
- the area can be divided as shown in FIG. 13, for example.
- the area indicated by the symbol D is hierarchized, and a plurality of contents can be allocated.
- the area hierarchical structure at this time is as shown in FIG.
- a hierarchical structure is added as PluginLayoutArea as indicated by a broken line in FIG.
- FIG. 15 shows the content allocated to such an area.
- the content includes “Night View”, “Large Gadget”, “Speed (“ Vehicle Speed ”displayed on the meter panel”), “Speed (“ Vehicle Speed ”displayed on the head-up display)”, “Lane / Turn-by-turn, “tachometer”, “ACC (adaptive cruise control)”, “energy flow”, “shift position”, “fuel gauge”, “outside temperature”, “odd trip”, “notification”, “small gadget” ",” Small mail “,” large mail “.
- Each content is associated with an information value and a content size. For the content “large gadget”, the information value becomes “0” when traveling (S102 in FIG. 5).
- FIG. 16A Under the premise that the information value of the content exceeds the area value of the area, in FIG. 16A, three contents of “lane / turn by turn”, “ACC”, and “energy flow” are displayed on the meter panel. Assigned to the central area.
- a content list is created in order from the content with the largest information value, including the content of “Night View” in the active state (S110 in FIG. 4). Then, the contents are allocated to the areas in order from the top of the content list, that is, in order from the content having the larger information value (S170).
- “Night View” has the information value “130”.
- “lane / turn by turn” has an information value of “95”
- “tachometer” has an information value of “90”
- “ACC” has an information value of “85”
- “energy” has an information value of "80”.
- the night view of the information value “130” is preferentially assigned to the central area of the meter panel.
- the content of “lane / turn by turn” driven out by the content of “night view” is allocated to the left area of the meter panel. This is because the information value of the “lane / turn by turn” content is larger than the content of the “tachometer”.
- FIG. 18A the contents of “lane / turn by turn” and “speed (HUD)” are displayed in the area of the head-up display.
- the content of “energy flow” is displayed in the center area of the meter panel.
- a content list is created in order from the content with the largest information value, including the content of “Night View” in the active state (S110 in FIG. 4). Then, the contents are allocated to the areas in order from the top of the content list, that is, in order from the content having the larger information value (S170).
- the content of “Night View” is preferentially allocated to the area of the head-up display.
- the content of “lane / turn by turn” and the content of “energy flow” driven to the content of “night view” are allocated to the central area of the meter panel.
- the content of “speed (HUD)” is not displayed because it is a digital display content for a head-up display.
- contents whose display state as an attribute is “active state” are extracted, rearranged in descending order of information value, and a content list is created (S110 in FIG. 4).
- content is allocated to areas (S170), and a combination of content and area is determined. That is, the combination with the area is determined by repeating the same processing in the order of the content list.
- a content parameter including at least one of a content evaluation value indicating the priority of content display and a content size indicating the size of the content display content is set for each of the plurality of contents.
- the area parameters including at least one of the area evaluation value indicating the content allocation priority and the area size indicating the size of the display area of the area are set, and the order in which the content is allocated to the area is determined based on the content parameter. In accordance with the order, it is determined whether there is an area in which the content can be displayed based on the relationship between the content parameter and the area parameter, and the combination of the content and the area is sequentially determined based on the determination.
- 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 assigned to the area (in FIG. 4). S170). That is, when the content allocation control unit determines whether there is an area where content can be displayed based on the relationship between the content parameter and the area parameter, the content evaluation value included in the content parameter and the area included in the area parameter The evaluation value is compared, and when the content evaluation value is larger than the area evaluation value, it is determined that there is an area that can be displayed. That is, in this embodiment, content is assigned to an appropriate area by associating information value with content and associating area value with area. Thus, unlike the case of simply using priorities as in the prior art, content is allocated to an 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.
- the content to be allocated is allocated to the area having the greatest area value (S170 in FIG. 4). Thereby, since content is allocated from an area with a larger area value, it is possible to display information that can be easily grasped by the user.
- a content list is created by rearranging in order from the content having the largest information value (S110 in FIG. 4). That is, when determining the order in which content is allocated to areas, the content allocation control unit determines the content evaluation value included in the content parameter in descending order. As a result, since the content with the larger information value is allocated to the area with the larger region value in order, the effect of arranging the content in an appropriate area is conspicuous.
- the content size and the area size are compared, and an area having an area size smaller than the content size of the content to be allocated is excluded (S150 in FIG. 4). That is, when the content allocation control unit determines whether there is an area in which content can be displayed based on the relationship between the content parameter and the area parameter, the content size included in the content parameter and the area size included in the area parameter When the content size is smaller than the area size, it is determined that there is an area that can be displayed. Thereby, it is not necessary to scroll and display the content, or to reduce and display the content, and it is possible to display information that can be easily grasped by the user.
- the area management unit 12 has an area hierarchical data structure (see FIG. 3), and content is allocated based on this hierarchical data structure when content is allocated. Are excluded (S140 in FIG. 4). Thereby, the parent-child relationship between areas can be determined easily, and the area which can be allocated can be determined rapidly.
- the value of the content and the area is changed based on the traveling state of the vehicle (S100 in FIG. 4). Specifically, when the vehicle is traveling (S101 in FIG. 5: YES), the information value and the region value during traveling are changed (S102, S103), while the vehicle is stopped (in FIG. 5). (S101: NO), the information value and the area value during the stop are changed (S104, S105). That is, the content evaluation value is changed according to the vehicle situation, and when the content evaluation value is changed, the content allocation control unit re-determines the order in which the content is allocated to the area, and further determines the order.
- “display state” as an attribute is associated with the content (see FIG. 2A), and only the content whose display state is “active information” is displayed. (Assignment target). Thereby, it is possible to easily manage whether or not the content is to be displayed.
- the allocation management unit 13 manages in advance the correspondence between a part of the content and the area corresponding to the content (see FIG. 2B). Content allocation is performed with priority on this correspondence. Thereby, content can be allocated to a more appropriate area, and its design can be ensured. Moreover, a desired content can be allocated to an area desired by a user.
- various contents are acquired via the network in the vehicle (see FIG. 1).
- 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.
- “area value” and “area 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.
- the combination of the content and the area is determined depending on whether or not the information value as the content information exceeds the area value as the area information.
- an evaluation value is calculated from the content value as the content information and the area suitability as the area information, and the combination of the content and the area is determined based on the evaluation value.

- the display target person is a driver, a passenger on the front passenger seat, and a passenger on the rear seat.
- the value of the content varies depending on the display target person.
- content such as “vehicle speed” and “engine speed” is valuable information for the driver. Therefore, each content has three values: a content value [driver], a content value [passenger passenger], and a content value [rear passenger].
- the content value is stored as a numerical value of “0” or more.
- the display target person is a driver, a passenger on the passenger seat, and a passenger on the rear seat.

- Content that requires expressiveness is content with a large amount of information, such as a “map” for navigation.
- the operation characteristic is set as an index indicating whether or not an operation on the content is necessary in five stages from “1” to “5”, and the value is larger as the content requires the operation.
- Examples of the content that needs to be operated include an “audio control panel” in the sense that an operation such as selecting a playback music occurs.
- the characteristics are expressed in five stages “1” to “5”, but the present invention is not limited to this. What is necessary is just to divide into at least two or more steps.
- the area management unit 12 associates three attributes (parameters) such as “area suitability”, “area size”, and “area characteristics” with each area.
- a storage device storage unit
- the area suitability is an index indicating the visibility of the area for each display target person.
- the display target person is a driver, a passenger on the front passenger seat, and a passenger on the rear seat. That is, the area suitability varies depending on the display target person. For example, the area suitability of the meter panel is increased for the driver, and the area suitability of the area of the liquid crystal display device for displaying a map for navigation is increased for the driver and the passenger on the passenger seat. Therefore, each area has three suitability levels: area suitability [driver], area suitability [passenger seat passenger], and area suitability [rear seat passenger]. In the present embodiment, the area suitability is shown in 10 stages of “1” to “10”. However, it is not limited to this.

- these aptitude degree tables express aptitude degrees in 10 stages from “1” to “10”, and the value increases as the aptitude degree increases. As with the area suitability, the expression is not limited to 10 levels.
- the suitability degree for each characteristic is calculated from the content characteristics of each content and the area characteristics of each area by using these suitability degree tables. For example, a “map” for navigation with a large amount of information has an expressive characteristic of “5” as content that requires expressiveness, and an area of a liquid crystal display device with high expressiveness has an expressive characteristic of “5”. It shall be. In this case, in the example of FIG. 7B, the expressiveness aptitude is calculated as the maximum value “10”.

For example, if there is content X, Y, Z, W and the content value is X> Y> Z> W, if the content in the “active state” is “X, Z, W”, the content list is , “X ⁇ Z ⁇ W”.
- N pieces of content are rearranged.
- the mandatory exclusive constraint expression is processed. Even if the required exclusive constraint expression is applied to the content of the content list as it is, the required exclusive constraint expression includes content whose display state is “inactive state”. For this reason, in the present embodiment, a process is performed in which an essential exclusive constraint expression including content that is in an “inactive state” in advance is replaced with an equivalent simpler essential exclusive constraint expression. That is, when a content that is not a display target is included in the mandatory exclusive constraint expression, the required exclusive constraint expression is rewritten to a constraint expression of the content that is the display target. As a result, it is possible to prepare an essential exclusive constraint expression without worrying about whether the content is “active state” or “inactive state”.

For example, as shown in FIG. 8C, it is assumed that there is an indispensable exclusive constraint expression “X ⁇ Z”, and if the content list created in S110 is “X ⁇ Z ⁇ W”, For example, two content lists “X ⁇ W” and “Z ⁇ W” are created. Here, since either X or Z is indispensable display, X and Z are arranged at the head. In this way, the content related to the mandatory exclusive constraint expression is arranged at the top of the list. After that, the context between each content is rearranged based on the content value. At this time, for example, the sorting is performed based on the content value for the driver. Of course, rearrangement using content values for passengers in the front passenger seat and passengers in the rear seat may be performed. In the following description, it is assumed that M new lists have been created.

- 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.
- content is allocated to the area.
- content is allocated to an area having an area size closest to the content size of the content among the areas targeted up to S160.
- content is allocated to areas in the order of the content list (S170 in FIG. 4), and the combination of content and area is determined. That is, the order in which content is allocated to areas is determined based on the content parameters, and according to the order, it is determined whether there is an area where content can be displayed based on the relationship between the content parameters and the area parameters. Based on this, a combination of content and area is sequentially determined. That is, the combination with the area is determined by repeating the same processing in the order of the content list. Thereby, it is possible to realize content arrangement with a high degree of freedom by a relatively simple process.
- the content size is compared with the area size, and an area having an area size smaller than the content size is excluded (S150 in FIG. 4). Is assigned (S170). That is, when the content allocation control unit determines whether there is an area in which content can be displayed based on the relationship between the content parameter and the area parameter, the content size included in the content parameter and the area size included in the area parameter When the content size is smaller than the area size, it is determined that there is an area that can be displayed. Then, content is allocated to the area having the closest size. This makes it possible to display information that is easy for the user to grasp because the content is allocated to the area by the balance between the content size and the area size, unlike the case of simply using the priority order as in the prior art.
- “display state” as an attribute is associated with content (see FIG. 11), and only content whose display state is “active information” is to be displayed (assignment target). )become. Thereby, it is possible to easily manage whether or not the content is to be displayed.
- the area management unit 12 has an area hierarchical data structure (see FIG. 3), and content is allocated based on this hierarchical data structure when content is allocated. Are excluded (S140 in FIG. 4). Thereby, the parent-child relationship between areas can be determined easily, and the area which can be allocated can be determined rapidly.
- the allocation management unit 13 manages in advance the correspondence between a part of the content and the area corresponding to the content (see FIG. 2B). Content allocation is performed with priority on this correspondence. Thereby, content can be allocated to a more appropriate area, and its design can be ensured. Moreover, a desired content can be allocated to an area desired by a user.
- various contents are acquired via the network in the vehicle (see FIG. 1).
- the content management unit 11 similarly manages “content size” and “display state” in association with various contents.
- content can be allocated to an area with the same algorithm regardless of the type of content.
- “area size” is 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.
- the content is allocated to the areas in the order of the content list on the assumption that the information value of the content exceeds the area value of the area.
- each content is various, and there is a request that cannot be realized by allocation based on information value and domain value. For example, it is required to ensure that necessary content is properly allocated to some area, or to prevent redundant content from being displayed redundantly in a plurality of areas. Therefore, the essential exclusion constraint formula as described above is used. A specific example of the mandatory exclusive constraint expression will be described.
- FIGS. 22A and 22B it is assumed that the content of “large gadget”, “notification”, and “small gadget” is active. It is assumed that “large gadget” and “small gadget” are contents for notifying incoming calls. The same applies to the following. As shown in FIG. 15, “large gadget” has an information value of “120”, “notification” has an information value of “53”, and “small gadget” has an information value of “50”. It has become.
- “Large Gadget & Small Gadget” is used as the constraint equation.

- “large gadget ⁇ small gadget” is used as a constraint expression.
- “large gadget ⁇ small gadget” means that either “large gadget” or “small gadget” is displayed. Since the content of “large gadget” has an information value of “120”, it is allocated before the content of “small gadget” having an information value of “50”. Therefore, when “large gadget” is displayed in the center area of the meter panel, “small gadget” is not displayed in the upper right area of the meter panel (see FIG. 24B).
- “large gadget / small gadget” is used as the constraint equation.
- “Large Gadget / Small Gadget” means that either “Large Gadget” or “Small Gadget” is displayed, or neither is displayed. Therefore, if there is a “notification” content with higher information value, the “notification” content is displayed in the upper right area of the meter panel (see FIG. 25B).
