And an internal memory such as a RAM for storing the program and various data. In particular, the display control program according to the present embodiment is installed in the display control device 80 via an arbitrary recording medium or network, so that each unit of the control unit 81 is substantially configured.

  The control unit 81 includes an importance level acquisition unit 81a, an influence level specification unit 81b, a switching mode determination unit 81c, and a route guidance unit 81d in terms of functional concept. The importance level acquisition unit 81a is an importance level acquisition unit that acquires the importance level of information output from the monitor 60 or the panel 70 after the output of the monitor 60 or the panel 70 is switched.

As a specific route guidance method of the route guidance unit 81d, a known method used in a car navigation device can be used. Details of processing executed by each component of the control unit 81 will be described later.

(Configuration-Display control device-Data recording unit)
The data recording unit 82 is a recording unit that records a program and various data necessary for the operation of the display control device 80, and is configured using, for example, a hard disk (not shown) as an external storage device. However, any other recording medium including a magnetic recording medium such as a magnetic disk or an optical recording medium such as a DVD or a Blu-ray disk can be used instead of or together with the hard disk.

  The data recording unit 82 includes an importance database (hereinafter referred to as “DB”) 82a, a map information DB 82b, an influence map 82e, and a control table 82f. The importance DB 82a is importance information storage means for storing information output from the monitor 60 and the panel 70 and importance information for specifying the importance for the user of the information in association with each other. FIG. 2 is a diagram illustrating information stored in the importance DB 82a. As illustrated in FIG. 2, the importance DB 82 a includes items “output contents” and items “importance” as DB items, and information corresponding to these items is stored in association with each other. The information stored corresponding to the item “output content” is information output from the monitor 60 and the panel 70 and information specifying the output state. For example, each information and the name of the output state can be stored. The example of FIG. 2 shows a state in which “vehicle approach warning” is stored as the name of information and “monitor luminance” is stored as the output state. The information stored corresponding to the item “importance” is information output from the monitor 60 and the panel 70 and importance information for specifying the importance of the output state. For example, is the information and the output state important? A numerical value indicating whether or not and identification information can be stored. In the example shown in FIG. 2, when the importance level is “low”, the importance level of the information and the output state is low, when “high” level, the importance level is medium, and when “high” level, the importance level is low. Is large. The importance can be determined by any method. For example, the importance can be determined based on the degree of necessity of prompt notification to the user (in particular, the driver in this case). ) Sets the importance level high, and sets the importance level low for information that is not necessary (for example, output status).

  Returning to FIG. 1, the map information DB 82b is map information storage means for storing map information. The “map information” includes, for example, search data and map data for the route guidance unit 81d to search and guide a route, and includes attention level information 82c and history information 82d. . Of these, the attention level information 82c is information that specifies the level of attention required when the vehicle travels in a predetermined area. For example, the driver should pay particular attention to a school zone, an intersection, an accident-prone area, or the like. The attention level can be set high for the area to be paid for. A specific method for setting the attention level is arbitrary, but here, it is set by one of the numerical values “1”, “2”, and “3” as shown on the horizontal axis of FIG. The history information 82d is history information 82d related to the history of the vehicle traveling in a predetermined area, and includes information for specifying the road traveling frequency and the destination setting frequency, for example. However, when there is a point registered with a predetermined name (for example, “home”) that is assumed to have a high traveling frequency, the history information 82d may be substituted with the name.

  The influence degree map 82e is a map that is referred to when the influence degree specifying unit 81b specifies the influence degree. FIG. 3 is a diagram illustrating an influence map 82e. In the example of FIG. 3, the influence map 82 e indicates the “attention level” specified based on the attention level information 82 c on the horizontal axis and the predetermined operation related to the output of the monitor 60 or the panel 70 acquired via the operation unit 20. When the “operation state” specified based on the presence / absence is on the vertical axis, the degree of influence corresponding to these “attention level” and “operation state” is shown. In the example illustrated in FIG. 3, the horizontal axis “attention level” corresponds to the size of the attention level specified by the attention level information 82 c, and the larger the numerical value, the higher the attention level. Further, the vertical axis “operation state” indicates that the presence or absence of a predetermined operation relating to the output of the monitor 60 or the panel 70 (for example, the presence or absence of an operation that directly changes the navigation screen, the operation content such as the operation of the headlight, etc. indirectly. And the presence or absence of an operation reflected in the output of the panel 70), the smaller the numerical value, the higher the relevance with the output of the monitor 60 or the panel 70 is. For example, “3” of “operation state” indicates that there is no operation related to the output of the monitor 60 or the like, “2” indicates that an operation is indirectly reflected in the output of the monitor 60 or the like, and “1” indicates that the monitor 60 When there is an operation for directly changing the output such as 60, it can be associated with each other. Although omitted here, in practice, an operation state table configured by associating each operation with the operation state is stored in the data recording unit 82, and when there is an operation by the driver, The operation state corresponding to this operation may be acquired from the operation state table.

  By specifying these “attention level” and “operation state”, the corresponding degree of influence can be specified. For example, when “attention level” and “operation state” are both “1” in FIG. 3, the degree of influence is “small”. This is a situation in which the driver has room to view the monitor 60 or the like when driving in an area where the driver does not need to pay particularly high attention, and an operation for directly changing the output of the monitor 60 or the like. When the driver performs the operation, it is considered that the driver himself predicts that the output switching will occur, indicating that the influence of the output switching of the monitor 60 or the like on the driver is small. .

  Returning to FIG. 1, the control table 82 f is used for reference when the switching mode determining unit 81 c determines the switching mode of the output of the monitor 60 or the like. FIG. 4 is a diagram illustrating information stored in the control table 82f. As shown in FIG. 4, the control table 82 f includes items “impact” and item “importance” as table items, and the levels of these “impact” and “importance” (in the example of FIG. 4, Information for specifying the switching mode corresponding to “large”, “medium”, and “small” for each of “influence” and “importance” (“immediate” and “slow” in the example of FIG. 4) is stored. Yes. The meaning of the information specifying this switching mode will be described later.

(processing)
A display switching process executed by the display control system 1 configured as described above will be described. FIG. 5 is a flowchart of the display switching process (in the following description of each process, step is abbreviated as “S”). This display switching process is automatically activated after the display control system 1 is powered on. After the power is turned on, the switching mode determining unit 81c monitors whether or not a predetermined display switching timing has arrived (SA1). Specifically, the switching mode determination unit 81c displays based on the vehicle position such as the vehicle position, the vehicle speed, obstacle information from a sensor for monitoring the surroundings, or a time measured by a known timer (not shown). It is determined whether or not the switching timing has arrived.

  For example, when it is determined by a known inter-vehicle sensor or obstacle sensor that the host vehicle has approached another vehicle or obstacle, the switching mode determining unit 81c uses the output of the monitor 60 or the warning light on the panel 70 as the vehicle. It is determined that a display switching timing for switching to display contents for performing an approach warning or an obstacle approach warning has arrived.

  When the route guidance unit 81d outputs the route guidance information to the monitor 60, the route guidance unit 81d determines that the vehicle has approached the intersection based on the current position of the vehicle detected by the current location detection processing unit 50. In this case, when the route guidance unit 81d instructs the switching mode determination unit 81c to switch the output of the monitor 60 from the general map display to the enlarged intersection view, the switching mode determination unit 81c performs the display switching timing. Is determined to have arrived. In addition, when the route guidance unit 81d determines that the vehicle has passed the prefectural border, an instruction to switch the output of the monitor 60 is displayed so that guidance information indicating the prefectural border passage is superimposed on a general map display. When the guidance unit 81d performs the switching mode determination unit 81c, the switching mode determination unit 81c determines that the display switching timing has arrived.

  Further, when the lighting state of the headlight is automatically changed based on the illuminance outside the vehicle detected by the illuminance sensor 40, or the driver inputs an operation input for changing the lighting state of the headlight via the operation unit 20. If so, the switching mode determination unit 81c determines that the display switching timing for switching the luminance of the monitor 60 or the panel 70 to the luminance corresponding to the lighting state of the headlight has arrived.

  Further, based on information relating to the driver's visual field detected by the visual field detection unit 10 (for example, the number and time of blinks of the driver, the pupil diameter, etc.), based on a known method for identifying the degree of fatigue of the driver. When a change in the driver's fatigue level is detected, the switching mode determination unit 81c changes the font size, line thickness, or color scheme of the monitor 60 displayed on the monitor 60 to the driver's fatigue level. It is determined that the display switching timing for switching to the state corresponding to is reached.

  In addition, when the user inputs a predetermined operation input to an in-vehicle device such as a car audio or a car air conditioner via the operation unit 20, the switching mode determination unit 81c displays a monitor 60 for guidance or the like corresponding to the operation input. It is determined that the display switching timing for switching the output has arrived.

  When it is determined that the display switching timing has arrived based on the determination criteria as described above (SA1, Yes), the importance level acquisition unit 81a is important to respond to information and output state output by the monitor 60 and the panel 70 after display switching. The degree is acquired from the importance DB 82a (SA2).

  Subsequently, the influence level specifying unit 81b sets the attention level set in the region including the current position of the vehicle detected by the current location detection processing unit 50 based on the attention level information 82c acquired from the map information DB 82b. Obtain (SA3). Further, the influence degree specifying unit 81b determines the presence / absence of a predetermined operation related to the output of the monitor 60 and the panel 70 via the operation unit 20, and acquires the operation state corresponding to the presence / absence of the operation (SA4).

  The influence degree specifying unit 81b refers to the influence degree map 82e, and specifies the degree of influence that the switching of the output of the monitor 60 or the like has on the driver based on the attention level acquired in SA3 and the operation state acquired in SA4. (SA5). Further, the switching mode determining unit 81c refers to the control table 82f, and determines the switching mode based on the importance level acquired by the importance level acquiring unit 81a in SA2 and the influence level specified by the impact level specifying unit 81b in SA5. (SA6). In the example shown in FIG. 4, the switching mode is determined to be “immediate” when the importance is “large” or the influence is “small”. Further, when the importance is “small” and the influence is “large” or “medium”, the switching mode is determined to be “slow”. Here, the switching mode “immediately” means that the output contents of the monitor 60 and the panel 70 are switched when the display switching timing arrives (strictly, when the processing of SA6 ends). In addition, “slow” as the switching mode means a switching mode that can reduce the influence on the driver due to the switching of the output as compared with “immediate”. For example, the screen displayed on the monitor 60 after the switching is transparent. Increase the rate step by step or gradually increase the screen size.

  For example, in the example shown in FIG. 2, for example, when the monitor 60 outputs an enlarged intersection map after display switching, the corresponding importance information is “1”, and the importance of the information after the display switching is medium. It is specified. Further, in the example shown in FIG. 3, the caution level set at the current position of the vehicle is the highest level (attention level = “3” in FIG. 3), such as when traveling in the school zone, and the monitor 60 If the operation state is such that there is no operation related to the output (operation state = “3” in FIG. 3), the influence level is specified to be the highest level. In such a case, the switching mode determining unit 81c determines that the switching mode is “slow” because the importance level is medium and the influence level is large. Alternatively, in the example shown in FIG. 3, the vehicle is traveling in the region where the attention level is set to the lowest level (attention level = “1” in FIG. 3), and the output of the monitor 60 etc. When the driver performs an operation that is indirectly reflected in the operation state (operation state = “2” in FIG. 3), it is specified that the influence level is a medium level. In such a case, the switching mode determining unit 81c determines that the switching mode is “immediate” because the importance level and the influence level are medium.

  Returning to FIG. 5, the switching mode determining unit 81c starts switching the monitor 60 and the panel 70 based on the switching mode determined in SA6 (SA7). Then, it is determined whether or not the switching has been completed (SA8). If the switching has not been completed (SA8, No), the process returns to SA3, and the influence level specifying unit 81b is set to an area including the current position of the vehicle. Get the attention level being. Thereafter, the processes from SA3 to SA8 are repeated until the switching is completed until it is determined in SA8 that the output switching is completed. When the switching mode is determined to be “slow” in SA6, the attention level acquired in SA3 and the operation state acquired in SA4 change before it is determined that the switching of “slow” is completed. When the influence degree specified in SA5 changes and the switching mode is determined to be “immediate” in SA6, the output is switched in the “immediate” switching mode (SA7).

  For example, when the vehicle is traveling in an area to be traveled with particular attention, such as a school zone (attention level = “3” in FIG. 3), and the driver performs an operation to change the brightness of the monitor 60 (Operation state in FIG. 3 = “1”) will be described. In this case, the importance DB 82a shown in FIG. 2 specifies that the importance of the information after display switching is the lowest level, and the influence map 82e shown in FIG. 3 specifies that the level of influence is the highest. The Accordingly, the switching mode is determined to be “slow” based on the control table 82f shown in FIG. In the middle of switching the slow display based on this determination, if the vehicle exits the school zone or the like and enters an area that does not require special attention (attention level = “1” in FIG. 3), the effects shown in FIG. Since the degree of influence becomes the smallest level by the degree map 82e, the switching mode is determined as “immediate” based on the control table shown in FIG. In this case, the slow display switching is interrupted and the immediate display switching is performed. As a result, when the driver changes from a situation where the driver should pay attention to the surroundings of the vehicle to a situation where the driver has a margin to view the monitor, the output can be switched as quickly as possible.

  Returning to FIG. 5, when it is determined that the output switching of the monitor 60 or the panel 70 has been completed (SA8, Yes), the process returns to SA1, and the switching mode determination unit 81c determines whether or not a predetermined display switching timing has arrived. Monitor (SA1). Thereafter, the processing from SA1 to SA8 is similarly repeated.

(effect)
As described above, according to the first embodiment, the mode of switching is determined based on the importance of information output from the monitor 60 and the panel 70 after switching and the degree of influence that the switching of output has on the driver. The output can be switched in a switching manner that takes into account the degree of influence that varies depending on the state of the vehicle and the state of the driver, and the influence on the driver can be reduced.

  In addition, the influence degree specifying unit 81b specifies the degree of influence that the output switching has on the driver based on the attention level set in the region including the current position of the vehicle, and thus is necessary when the vehicle travels. The output can be switched in a switching mode that takes into account different degrees of influence depending on the level of attention.

  Moreover, since the influence specific | specification part 81b pinpoints the influence which the switching of an output has on a driver based on the operation state of the driver regarding switching, the switching which considered the influence which changes with the kind and presence or absence of a driver | operator's operation The output can be switched in a manner.

[Embodiment 2]
Next, a second embodiment will be described. In this form, the influence degree is specified based on the driver's visual field information with respect to the monitor 60 and the panel 70. The configurations of the second embodiment and the subsequent embodiments are substantially the same as the configurations of the first embodiment unless otherwise specified, and this configuration is substantially the same as the configuration of the first embodiment. The same reference numerals and / or names as those used in Embodiment 1 are attached as necessary, and the description thereof is omitted.

(Configuration-Influence map)
The influence map stored in the data recording unit 82 of the display control apparatus 80 according to Embodiment 2 will be described. FIG. 6 is a diagram illustrating an influence map. As shown in FIG. 6, the influence degree map is identified based on the driver's visual field information acquired through the visual field detection unit 10 with the “attention level” identified based on the attention level information 82 c as the horizontal axis. The magnitude of the degree of influence corresponding to these “attention level” and “visual field” when the “visual field” is the vertical axis is shown. In the example illustrated in FIG. 6, the vertical axis “field of view” corresponds to the position of the monitor 60 and the panel 70 in the driver's field of view specified from the field of view information. It shows that the position is far from the driver's visual center. For example, “3” of “field of view” is “2” when the monitor 60 and the panel 70 are located in the vicinity of the center of the driver's field of view and the driver is looking at the monitor 60 and the like. When the monitor 60 and the panel 70 are located in the peripheral part of the driver's field of view and the driver is not looking at the monitor 60 or the like but is estimated to be visible, “1” is in the driver's field of view. When the monitor 60 and the panel 70 are not included and it is estimated that the driver cannot visually recognize the monitor 60 and the like, they can be associated with each other.

  By specifying these “attention level” and “field of view”, the corresponding influence degree can be specified. In the example of FIG. 6, when both “attention level” and “field of view” are “1”, the degree of influence is “small”. This is because when the driver is traveling in an area where it is not particularly necessary to pay high attention, the driver's attention is not drawn to the monitor 60 etc. more than necessary. Since it is considered that it cannot be visually recognized, it indicates that the influence of switching the output of the monitor 60 or the like on the driver is small. Further, when the “attention level” is “1” and the “field of view” is “3”, the influence degree is “small”. This indicates that since the driver is already looking at the monitor 60, the influence of switching the output of the monitor 60 or the like due to the driver's attention is relatively reduced. On the other hand, when the “attention level” is “1” and the “field of view” is “2”, the influence degree is “medium”. This is because although the driver does not look at the monitor 60 or the like, the monitor 60 or the like can be seen in the field of view, so by switching the output of the monitor 60 or the like to another monitor 60 or the like. This indicates that there is a possibility that the driver's attention may be drawn, and the degree of influence due to the switching is relatively increased.

(processing)
Next, display switching processing executed by the display control system 1 according to Embodiment 2 will be described. Since the display switching process in the second embodiment is the same as the display switching process described in the first embodiment except for the contents described below, the flowchart is not shown.

  In SA4 of the display switching process described in the first embodiment, the influence degree specifying unit 81b acquires the driver's visual field information for the monitor 60 and the panel 70 via the visual field detection unit 10 (SA4). Then, the influence degree specifying unit 81b refers to the influence degree map, and specifies the degree of influence that the switching of the output of the monitor 60 or the like has on the driver based on the attention level acquired in SA3 and the visual field information acquired in SA4. (SA5).

(effect)
As described above, according to the second embodiment, the influence specifying unit 81b specifies the influence that the output switching has on the driver based on the driver's visual field information on the monitor 60 and the panel 70. The output can be switched in a switching mode that takes into account the degree of influence that varies depending on the position of the monitor 60 or the like in the field of view.

[Modifications to Embodiments]
Although the embodiments of the present invention have been described above, the specific configuration and means of the present invention are arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. be able to. Hereinafter, such a modification will be described.

(About problems to be solved and effects of the invention)
First, the problems to be solved by the invention and the effects of the invention are not limited to the above contents, and may vary depending on the implementation environment and details of the configuration of the invention. May be solved, or only some of the effects described above may be achieved.

(About slow display switching)
In each of the above-described embodiments, when the switching mode determining unit 81c determines the switching mode to be “slow”, the screen transmittance displayed on the monitor 60 after switching is decreased stepwise, or the screen size is gradually increased. Although it has been explained that the influence is specified, the influence degree specified by the influence degree specifying unit 81b is changed, and the output switching is not started until the switching mode is determined to be “immediately” and the output is immediately switched, The screen before switching may be continuously displayed. As a result, for example, when a vehicle is traveling in an area that should be traveled with particular attention, such as a school zone, the vehicle is not switched until the vehicle exits the school zone and enters a safe area. Switching can be performed after entering the area.

(About the impact map)
In each of the above embodiments, the influence degree specifying unit 81b specifies the influence degree based on a two-dimensional influence degree map in which “attention level” is the horizontal axis and “operation state” or “field of view” is the vertical axis. However, the influence degree may be specified based on a three-dimensional influence degree map having “attention level”, “operation state”, and “field of view” as axes orthogonal to each other.

  Also, the road frequency and destination setting frequency specified based on the history information 82d relating to the history of the vehicle traveling in the predetermined area are set as the axes of the influence map, and the influence degree is specified based on this. May be. Thereby, an output can be switched in the switching mode which considered the influence degree which changes with the driving | running | working frequency etc. of a road.

  In addition, as the driver's operation state, an example in which the degree of influence is specified based on the operation state related to display switching has been shown, but the driver's operation state related to the vehicle may be considered. The degree of influence may be specified based on the handle angle. That is, the relationship between the vehicle speed and the attention level or the field of view is recorded in the data recording unit 82 as an influence degree map, and the influence degree is specified based on the speed of the vehicle at the time when the display switching timing arrives. The relationship between the angle and the attention level or the visual field may be recorded in the data recording unit 82 as an influence degree map, and the influence degree may be specified based on the handle angle at the time when the display switching timing arrives.

(About the control table)
In each of the above embodiments, the information specifying the switching mode stored in the control table has been described as two types of “immediate” and “slow”. For example, all or part of these two types It may be replaced with a switching mode such as “intermediate” that switches the screen at a speed between “immediate” and “slow”, a switching mode such as “display OFF”, or other switching modes may be added to provide three or more types. .
