Speedometer 101a is displayed in a large display size S ₂ at the time of high speed running, which makes it possible to improve the visibility of the running speed of the vehicle displayed on the display unit 101 at the time of high speed running. Therefore, the driver can accurately grasp information necessary for safe driving, such as the traveling speed, even during high-speed driving.

  In the first embodiment, the engine speed and the cooling water temperature are not displayed on the display unit 101 during high-speed traveling. Since these pieces of information are not displayed on the display unit 101, the visibility of the traveling speed of the host vehicle and the remaining amount of fuel, which are information displayed on the display unit 101, is enhanced. Therefore, the driver can accurately grasp information necessary for safe driving.

  In addition, when driving at low speed, the driver can view the display unit 101 with more margin than when driving at high speed. By displaying a large amount of information at a predetermined size during low-speed driving, the driver can accurately grasp information necessary for safe driving.

  The fuel gauge 101b is displayed in a constant display size regardless of the traveling speed. Therefore, the driver can always grasp information necessary for safe driving, such as the remaining amount of fuel, with a constant visibility regardless of the traveling speed.

  Thus, according to the first embodiment, in all speed ranges, the driver can accurately grasp information necessary for safe driving.

(Second Embodiment)
A second embodiment of the present invention will be described with reference to FIGS. The vehicle information display device according to the second embodiment has the same configuration as the vehicle information display device 100 according to the first embodiment except for display parameter data stored in the display parameter storage unit 103 (see FIG. 1). Therefore, also in the present embodiment, the corresponding constituent elements will be described with the same reference numerals as those in the first embodiment, and description of the corresponding constituent elements will be omitted.

  FIG. 7 is a diagram schematically showing display parameter data 203a to 203f according to the second embodiment. As shown in the figure, the display parameter data 203a and 203b relating to the traveling speed and the remaining amount of fuel are the same as the display parameter data 103a and 103b of the first embodiment, respectively, and thus detailed description thereof is omitted.

The display parameter data 203c to 203f according to the present embodiment includes display parameter data 203c and 203e relating to the engine speed, and display parameter data 203d and 203f relating to the temperature of the cooling water. The display parameter data 203c and 203d are the same as the display parameter data 103c and 103d according to the first embodiment, respectively. Wherein the display parameter data 203c~203f according to the present embodiment, between the second speed V ₂ and the third velocity V _3, where different priority and display parameters in the acceleration and deceleration is defined It is in.

When accelerating between the second speed V ₂ and the third speed V ₃ (V ₁ <V ₃ <V ₂ ), the display parameter indicated by the display parameter data 203c regarding the engine speed is the display size R _3. (R ₂ <R ₃ <R ₁ ) and display size R ₂ become smaller in proportion to the change in travel speed (difference between travel speed and third speed V ₃ ). Further, at this time, also display parameter indicated by the display parameter data 203d relating to the temperature of the cooling water, proportional to the change in speed between the display size _{T 3 (T 2 <T 3} <T 1) and the display size _{T 2} And get smaller.

Display contrast, when decelerating between the second speed V ₂ and the third velocity V _3, display parameter indicated by the display parameter data 203e relating to the rotation speed of the engine, the display size 0 (non-display) increases in proportion to the traveling speed variation between the size R ₃ (the difference between the second speed V ₂ and the traveling speed). Further, at this time, also display parameter indicated by the display parameter data 203f relating to the temperature of the cooling water increases in proportion to the change in speed between the display size 0 (non-display) and a display size T _3.

  The process which the vehicle information display apparatus which concerns on 2nd Embodiment performs is demonstrated with reference to FIG.8 and FIG.9. As shown in FIG. 8, the process executed by the vehicle information display device according to the second embodiment is substantially the same as the process executed by the vehicle information display device according to the first embodiment (see FIG. 3). The feature of the processing executed by the vehicle information display device according to the second embodiment is that after the display processing at high speed (step S112), the third traveling speed determination processing (step S513) and the non-display recovery processing (step S514). )It is in. In the present embodiment, the same processes as those in the first embodiment are denoted by the same reference numerals, and detailed descriptions thereof are omitted.

Display process (Step S112) is executed, the display parameter determination unit 104, the traveling speed is determined whether faster than the second speed _{V 2} (third traveling speed determining processing in step S513). If the running speed is judged to be faster than the second speed _{V 2} (step S513; Yes), the display parameter determination unit 104 returns to display the parameter determination process (step S110).

If the running speed is equal to or second speed _{V 2} less; a (step S513 No), the vehicle information display apparatus performs a hidden recovery process (step S514), then the engine stop determination process (step S113) Run.

Here, details of the non-display recovery process (step S514) will be described with reference to FIG.
The display parameter determination unit 104 determines the display size based on the display parameter data 203a, 203b, 203e, and 203f, and outputs the determination data (step S521).

  Details of the method for determining the display size in the display parameter determination process (step S521) will be described.

Display size of the speed meter 101a is determined by the same manner as the display parameter determination processing according to the first embodiment (step S107), and prorated according to the traveling speed between a display size S ₂ and the display size S ₁ Is done. Display size of the fuel gauge 101b is determined to a constant display size _{F 1.}

Display size of tachometer 101c is determined by pro rata in accordance with the running speed between 0 and the display size R _3. Specifically, the display size _{R 0} (not shown), when the traveling speed of the vehicle is represented by _{V 0,} (display size _R 0) / (Display Size _{R 3} - display size _R 0) = ( It is determined by a value satisfying the second speed V ₂ -V ₀ ) / (V ₀ -third speed V ₃ ).

Display size of the water temperature gauge 101d, as in the case of tachometer 101c, is determined by pro rata in accordance with the running speed between 0 and display size T _3.

As described above, in the second embodiment, the tachometer 101c and the water temperature gauge 101d are gradually displayed on the display unit 101 from the state where they are not displayed on the display unit 101 until the vehicle is decelerated from the high speed traveling to a constant speed. In contrast, if the tachometer 101c, for example, according to the first embodiment, and reaches the second speed V ₂ is decelerated from a high speed traveling, is displayed unexpectedly in display size R _2. According to this embodiment, when the display is restored from the non-display, it is possible to reduce the uncomfortable feeling given to the driver rather than suddenly displaying the information that was not displayed.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment described so far. The present invention includes, for example, the following modified examples, each embodiment and each modified example arbitrarily combined to the extent that they do not contradict each other, and each embodiment, each modified example, and a range that does not change the gist of the present invention, Includes a combination of these changes.

(Modification 1)
In the first embodiment, the traveling speed of the host vehicle during medium speed traveling, the engine speed, the cooling water temperature priority, and the display sizes of these display areas 101a, 101c, and 101d are proportional to the speed change. Therefore, it was decided to increase or decrease. However, the display size of these display areas 101a, 101c, and 101d during medium speed traveling only needs to be gradually increased or decreased according to the change in speed, and the method for that is limited to the method in the first embodiment described above. I can't. For example, the display size may change stepwise according to the change in speed. Further, for example, the display size may change according to a smooth curve that gradually increases or decreases according to a change in speed.

  Here, display parameter data according to the first modification is shown in FIG. FIG. 10 is a diagram schematically showing display parameter data 303a to 303d for changing the display size in stages. This figure shows the display parameter data 303a to 303d for the traveling speed, the remaining amount of fuel, the engine speed, and the cooling water temperature, as in FIG. The display parameter data 303a to 303d is different from the display parameter data 103a to 103d (see FIG. 2) according to the first embodiment in that the display size is changed stepwise during medium speed traveling.

  The vehicle information display apparatus 100 according to the first embodiment refers to the display parameter data 303a to 303d instead of the display parameter data 103a to 103d, and executes the processing (see FIG. 3) described in the first embodiment. Can do. Thereby, each information is displayed on the display unit 101 according to the display parameter data 303a to 303d. Even in this modification, as in the first embodiment, the driver can accurately grasp the information necessary for safe driving, and the driver feels a sense of discomfort caused by a sudden change in display size. It becomes possible to reduce.

(Modification 2)
In the first embodiment, the traveling speed, the engine speed, the cooling water temperature priority, and the display sizes of these display areas 101a, 101c, and 101d are gradually increased or decreased during medium speed traveling, It was assumed to be constant during high-speed driving. However, the priority of information and the display size of the display area may be gradually increased or decreased as appropriate in each traveling speed range.

  Here, display parameter data according to the second modification is shown in FIG. FIG. 11 is a diagram schematically showing display parameter data 403a to 403d for gradually changing the display size according to a change in speed during low-speed driving and medium-speed driving. This figure shows the display parameter data 403a to 403d for the traveling speed, the remaining amount of fuel, the engine speed, and the cooling water temperature, as in FIG. The display parameter data 403a to 403d is that the display size is changed in proportion to the change in speed not only during medium speed travel but also during low speed travel. 2).

The vehicle information display apparatus 100 according to the first embodiment refers to the display parameter data 303a to 303d instead of the display parameter data 103a to 103d, and executes the processing (see FIG. 3) described in the first embodiment. Can do. However, when the display parameter data 403a to 403d shown in FIG. 11 is used, the display parameter determination unit 104 determines the travel speed, the engine speed, and the coolant temperature in the first embodiment even during low speed travel. The display parameters are calculated and determined in the same way as during high speed driving. Specifically, for example, in the case of travel speed, the display parameter determination unit 104 determines the display size by dividing the display size S ₄ and the display size S ₁ according to the travel speed.

  Also according to this modification, as in the first embodiment, the driver can accurately grasp information necessary for safe driving.

(Modification 3)
In the first embodiment, the engine speed and the coolant temperature are not displayed during high-speed traveling, but these pieces of information may be displayed in a small size during high-speed traveling. FIG. 12 schematically shows examples of display parameter data 503a to 503d for displaying the engine speed and the coolant temperature even during high-speed running.

Of the display parameter data 503a to 503d according to this modification, the display parameter data 503a related to the traveling speed and the display parameter data 503b related to the remaining amount of fuel are the same as the display parameter data 103a and 103b according to the first embodiment, respectively. Yes (see FIG. 2). The difference between this modification and the first embodiment, among the display parameter data 503c and 503d regarding temperature of the rotational speed and the cooling water of the engine, there is a portion running speed according to the time of faster high-speed traveling than the second speed V _2.

Display parameter data 503c and 503d according to the present variation during high speed running, rather than hide the tachometer 101c and the water temperature gauge 101d, a data indicating that a small display size _{R 2} and _{T 2.}

  FIG. 13 shows a display example during high-speed traveling on the display unit 101 according to this modification.

The display sizes of the speedometer 101a and the fuel gauge 101b displayed on the display unit 101 in FIG. 13 are the same as the respective display sizes (see FIG. 6) displayed on the display unit 101 according to the first embodiment during high-speed traveling. is there. Display size of tachometer 101c and the water temperature gauge 101d displayed on the display unit 101 of FIG. 13 (width) is _{R 2} and _{T 2,} it is displayed on the display unit 101 according to the first embodiment at the time of medium speed running Each is smaller than the display size (see FIG. 5).

  According to this modification, information with high priority is displayed large during high-speed traveling, and thus visibility of information with high priority is increased. Moreover, since information with low priority is displayed small at the time of high-speed driving | running | working, the visibility of information with low priority becomes low. Thereby, the visibility of information with high priority during high-speed traveling is further enhanced. Therefore, as in the first embodiment, the driver can accurately grasp information necessary for safe driving.

  In the description so far, the display parameter is the display size. However, the display parameter affects the visibility of each information when the driver views the information displayed on the display unit 101. I just need it. In addition to the display size, the display parameters include, for example, display contrast of each information display area, display shape, display position, and the like, and these may be arbitrarily combined.

  The display contrast is easy to visually distinguish the background of each information display area such as the speedometer 101a, the fuel meter 101b, the tachometer 101c, and the water temperature meter 101d displayed on the display unit 101.

  The display contrast of the display areas 101a to 101d for each information is determined by, for example, the relationship between the hue, brightness, and saturation of the display areas 101a to 101d for each information and the hue, brightness, and saturation of the background. Generally, the contrast is high if the display color of the instrument and the background color have a complementary color relationship. Conversely, if the display color of the instrument is close to the background color, the contrast is low. Moreover, if the brightness | luminance which displays an instrument is high, contrast will be high, and if the brightness | luminance is low, contrast will be low. Furthermore, the contrast is high if the saturation displaying the instrument is vivid, and the contrast is low if the saturation is cloudy. If the contrast is high, the visibility is high, and if the contrast is low, the visibility is low.

  The display parameter data when the contrast is adopted as the display parameter may be obtained by replacing the vertical axis of the conceptual diagram of the display parameter data 103a to 103d shown in FIG. Thereby, the apparatus having the same configuration as that of the vehicle information display apparatus 100 according to the first embodiment is used, and the apparatus executes the same process as that of the first embodiment, and the same effect as that of the first embodiment is obtained. .

  The display shape is the shape of each information display area such as the speedometer 101a, the fuel gauge 101b, the tachometer 101c, and the water temperature gauge 101d displayed on the display unit 101. For example, in the embodiment, the shape of each display region is the same. However, when the area of each region is adopted as the display size, the display parameter data may be determined so that the display shape changes as the area changes. .

(Modification 4)
From here, the example which employ | adopts a display position as a display parameter is demonstrated with reference to FIGS. The display position is the position of the display area of each information on the display unit 101. For example, the display position is represented by a distance from a reference position defined in the display area of the display unit 101 to a point defined in the display area of each information. The reference position is preferably a position where the driver can easily see the entire area where information is displayed on the display unit 101. Thereby, the visibility of the information becomes higher as the display position of the information becomes smaller, and the visibility of the information becomes lower as the display position of the information becomes larger. In this case, the higher the priority is, the smaller the display position is, and the priority is expressed by, for example, the reciprocal of the display position.

  FIG. 14 schematically illustrates examples of display parameter data 603a to 603d according to the fourth modification. In the figure, the horizontal axis represents the traveling speed V, and the vertical axis represents the display position as a display parameter. In this modification, the reference position is the center (center of gravity) of the display unit 101. In this modification, the point defined in the display area of each information is the center (center of gravity) of the display area of each information.

  Display parameter data 603a to 603d shown in FIG. 14 includes display parameter data related to the traveling speed of the host vehicle, the remaining amount of fuel, the engine speed, and the coolant temperature, as in the first embodiment.

Display parameter data 603a indicated by a solid line in FIG. 14 relates to the traveling speed of the host vehicle. Display parameter data 603a shown in the figure shows that low-speed running during a display position S ₁ at a lower priority, a display position at a higher priority during high-speed running S _{2 (<S 1).} Display parameter data 603a, during medium speed, in proportion to the change in the running speed (the difference between the running speed and the first speed V _1), between a display position S ₁ and the display position S _2, priority It shows that the display position gradually decreases as the height increases.

Display parameter data 603b indicated by a broken line in FIG. 14 relates to the remaining amount of fuel. Display parameter data 603b indicate that a certain priority and display position F ₁ regardless of the running speed.

Display parameter data 603c indicated by a one-dot chain line in FIG. 14 relates to the engine speed. Further, the display parameter data 603d shown by the two-dot chain line in FIG. 14 relates to the temperature of the cooling water. Each display parameter data 603c and 603d, a display position _{R 1} and _{T 1} at a higher priority at the time of low-speed running, the display position at a lower priority at the time of high speed running _R 2 (> _{R 1)} and _T 2 _{(> T} 1) Indicates that Each display parameter data 603c and 603d, when medium speed, a change in running speed (the difference between the running speed and the first speed V ₁₎ is higher priority is lowered greatly, the display position in proportion to the change in the running speed The display position gradually increases between R ₁ and T ₁ and the display positions R ₂ and T ₂ .

  The vehicle information display device 100 (see FIG. 1) in which the display parameter data 603a to 603d according to this modification is stored in the display parameter storage unit 103 is processed by the vehicle information display device 100 according to the first embodiment (see FIG. 3). 15 to 17 show examples of the display unit 101 when the above is executed. FIG. 15 shows a display example during low-speed traveling. FIG. 16 shows a display example during medium speed running. FIG. 17 shows a display example during high-speed traveling. In FIGS. 15 to 17, concentric circles centered on the reference position are indicated by dotted lines in order to make the change in the display position easy to understand.

  In the display parameter data 603a shown in FIG. 14, it is determined that the priority and visibility of the traveling speed of the host vehicle increase as the traveling speed increases. Therefore, as shown in FIGS. 15 to 17, the display position of the speedometer 101a approaches the reference position as the traveling speed increases. Further, the display parameter data 603b is determined so that the priority and visibility of the remaining amount of fuel are constant regardless of the traveling speed. Therefore, the display position of the fuel gauge 101b is at a constant reference position regardless of the traveling speed. Further, the display parameter data 603c and 603d are set such that the priority and visibility of the engine speed and the temperature of the cooling water decrease as the traveling speed increases. Therefore, the display positions of the tachometer 101c and the water temperature gauge 101d become farther from the reference position as the traveling speed increases.

  In this modification, the display position is a distance from the reference position, but directions such as up, down, left and right with respect to the reference position may be further added to the display position. For example, in the case of an automobile, the driver is most likely to see the vicinity of the center of the road. Therefore, when the automobile is a right-hand drive, the left side of the instrument panel is considered to be a higher visibility than the right side. Further, depending on the height of the driver seat, the position of the handle, and the like, a difference between a portion with high visibility and a portion with low visibility in the entire area of the display unit 101 may occur.

  The display parameter may be combined with the display position and the display size. Since the displayable area in the display unit 101 is limited, it may be necessary to move the display position as the display size increases. In such a case, it is desirable to consider the relationship between the display position and the visibility described in the present modification in the movement direction.

  According to this modification, as in the first embodiment, the visibility of information whose priority increases as the traveling speed increases increases during high-speed traveling. Therefore, the driver can accurately grasp information necessary for safe driving.

  In addition, the visibility of information whose priority decreases as the traveling speed increases decreases during high-speed traveling. As a result, the visibility of information having a high priority during high-speed driving is further improved, so that the driver can accurately grasp information necessary for safe driving.

  In addition, since the display position gradually changes, it is possible to reduce the uncomfortable feeling given to the driver when the display position changes.

(Modification 5)
In the display parameter data described so far, the priority of each information is indicated by the display parameter. The configuration of the display parameter data is not limited to this. For example, the display parameter data may include state-priority data in which the state of the host vehicle and the priority of each information are associated, and priority-display parameter data in which the priority and display parameters are associated. The vehicle information display device according to such a modification has a configuration substantially similar to that of the vehicle information display device 100 according to the first embodiment, and includes a display parameter storage unit 703 that replaces the display parameter storage unit 103, and a display parameter determination unit. A display parameter determination unit 704 in place of 104.

As shown in FIG. 18, the display parameter storage unit 703 stores display parameter data including state-priority data 703a to d and priority-display parameter data 703e.
FIG. 19 is a diagram schematically illustrating state-priority data 703a to 703d according to the present modification. FIG. 19 is obtained by replacing the vertical axis of FIG. 2 with the priority from the display size, and the state-priority data 703a to d shown in FIG. 19 includes the traveling speed of the own vehicle as the state of the own vehicle, The relationship with the priority of each information displayed on the display part 101 is shown. The state-priority data 703a relates to the traveling speed of the own vehicle. The state-priority data 703b relates to the remaining amount of fuel. The state-priority data 703c relates to the engine speed. The state-priority data 703d relates to the temperature of the cooling water.

  FIG. 20 is a diagram schematically showing priority-display parameter data 703e according to the present modification. The priority-display parameter data 703e according to this modification is an example of the priority-display parameter data in which the priority and the display parameter are associated with each other so that the higher the priority is, the higher the visibility in the display unit 101 is. is there. In detail, as shown in FIG. 20, the priority-display parameter data 703e according to this modification has a display size of 0 (non-display) as a display parameter when the priority is 0, and is proportional to the priority. The display size is related to increase.

  In the priority-display parameter data, the relationship between the priority and the display parameter may be determined so that the display size is 0 (non-display) when the priority is a predetermined value or less.

  As shown in FIG. 18, the display parameter determining unit 704 according to the present modification includes a priority specifying unit 721 and a display parameter specifying unit 722. The priority specifying unit 721 acquires speed data as state data from the display data acquisition unit 102, and refers to the state-priority data 703a to d included in the display parameter data in the display parameter storage unit 703. Thus, the priority specifying unit 721 specifies the priority of each information corresponding to the traveling speed of the host vehicle as the state of the host vehicle, and generates priority data indicating the priority of each specified information.

  Further, the display parameter specifying unit 722 acquires priority data from the priority specifying unit 721 and refers to the priority-display parameter data 703e included in the display parameter data in the display parameter storage unit 703. Accordingly, the display parameter specifying unit 722 specifies the display parameter of each information associated with the priority of each information. Then, the display parameter specifying unit 722 determines the display parameter of each specified information as a display parameter for displaying each information on the display unit 101, and determines the determination data of each information indicating the determined display parameter of each information. Output.

  The vehicle information display device according to the present modification executes the same processing (see FIG. 3) as the vehicle information display device 100 according to the first embodiment, so that the display unit 101 has each of the same as in the first embodiment. Information display areas 101a to 101d are displayed according to the traveling speed (see FIGS. 4 to 6). Therefore, according to the present modification, as in the first embodiment, the driver can accurately grasp information necessary for safe driving in all speed ranges.

(Modification 6)
So far, the state of the own vehicle has been described as the traveling speed, but the state of the own vehicle is not limited to this. For example, when the cooling water temperature or the remaining amount of fuel is adopted as the state of the vehicle, and any of these indicates an abnormal value, the display parameter data for increasing the priority and visibility of the information indicating the abnormal value is provided. It may be determined. In this case, the display parameter storage unit 103 further stores display parameter data that gives higher priority when the state of the vehicle is an abnormal value than when the vehicle is not an abnormal value.

As a specific example, an example in which the temperature of the cooling water is an abnormal value when the temperature of the cooling water exceeds 90 degrees can be given. When this specific example is incorporated into the first embodiment, the display parameter data regarding the temperature of the cooling water when the cooling water temperature is less than 90 degrees may be the same as the display parameter data 103d according to the first embodiment. . The display parameter data relating to the temperature of the cooling water when the water temperature of the cooling water exceeds 90 degrees, may be any data to display the water temperature gauge 101d size T ₁ or more display size regardless traveling speed .

As a specific example, when the fuel is gasoline, an example in which the remaining amount of gasoline is an abnormal value when the remaining amount of gasoline becomes 5 liters or less can be given. When this example is incorporated into the first embodiment, the display parameter data regarding the remaining amount of gasoline when the remaining amount of gasoline is greater than 5 liters may be the same as the display parameter data 103b according to the first embodiment. The display parameter data relating to the remaining amount of gasoline when the remaining amount of gasoline is equal to or less than 5 liters may be any data that larger display size than the display size F ₁ fuel gauge 101b regardless to the running speed .

  In this modification, when the state of the own vehicle is an abnormal value, the priority of the state of the own vehicle is increased and the visibility is increased. As mentioned as a specific example, it is dangerous for the temperature of the cooling water to rise abnormally, running out of fuel, etc. while driving, but according to this modification, the driver can accurately and accurately detect them in advance. I can grasp it. Therefore, also according to this modification, the driver can accurately grasp information necessary for safe driving.

(Modification 7)
Further, for example, the setting of the host vehicle may be adopted as the state of the host vehicle, and the display parameter storage unit 103 may store display parameters corresponding to each setting.

  Specifically, an example in which a mode related to a transmission (not shown) is adopted as the setting of the own vehicle can be given. In this case, the display parameter storage unit 103 may store, for each mode, a set of display parameter data regarding the traveling speed of the host vehicle, the remaining amount of fuel, the engine speed, and the temperature of the cooling water.

  As a set of display parameters when the transmission mode is selected as a sport mode in which a high engine speed range is frequently used or a mode in which the gear ratio of the transmission can be selected by a user operation, the traveling speed increases. Alternatively, the display parameter storage unit 103 may store information that does not hide the display of the tachometer 101c and the water temperature gauge 101d. Alternatively, as a set of display parameters when these modes are selected, the display size of the speedometer 101a is increased as the traveling speed increases, and the display size of the tachometer 101c is set to a large display size in advance regardless of the traveling speed. Something may be stored in the display parameter storage unit 103.

  Further, display parameter data 103 a to 103 d similar to those in the first embodiment may be stored in the display parameter storage unit 103 as a set of display parameters when other modes are selected.

  Like this modification, the priority of each information can be changed by the setting of the own vehicle. In the sport mode given as a specific example, driving is often performed while paying particular attention to the engine speed. In addition, it is necessary to pay attention to the temperature of the cooling water and the traveling speed as appropriate. In the sport mode, by increasing the priority of the engine speed and appropriately increasing the priority of the cooling water temperature and the traveling speed of the vehicle, the user can accurately grasp the information. . Thus, by changing the priority of each information according to the setting of the vehicle, the driver can accurately grasp information necessary for safe driving.
