  FIG. 1 is a schematic configuration for explaining an entire vehicle including a vehicle display device according to an embodiment of the present invention, FIG. 2 is a front view of a combination meter, and FIG. 3 is a block configuration of a control means. is there. In this embodiment, the case where the present invention is applied to a vehicle equipped with a manual transmission is described.

  As shown in FIG. 1, an engine 2 is mounted on the vehicle 1, and the rotation of the engine 2 is transmitted to driving wheels (for example, front wheels) 4 via a manual transmission 3. Further, the vehicle 1 is provided with a combination meter 5 as a display device, and the combination meter 5 is installed on a dashboard in front of the driver's seat.

  As shown in FIG. 2, the combination meter 5 includes a speedometer 11 and a tachometer 12, and a fuel gauge 13 and a water temperature gauge 14 are provided between the speedometer 11 and the tachometer 12. And between the fuel gauge 13 and the water temperature gauge 14, the display means 6 which performs the display which prompts the operation to the gear stage in which a fuel consumption becomes favorable is provided. In a vehicle equipped with an automatic transmission, the position of the current shift state may be displayed at the position of the display means 6.

  As shown in FIG. 1, the vehicle 1 includes a control unit 8. The control unit 8 includes information on the rotational speed of the engine 2, information on the output of the engine 2, information on a throttle opening (accelerator opening), Information on the gear position of the manual transmission 3, information on the clutch signal, and the like are input.

  As shown in FIG. 1 and FIG. 3, the control means 8 is provided with a storage means 9, and the storage means 9 stores a fuel consumption classification map in which the fuel consumption situation is classified (see FIG. 4B described later). ). In the fuel efficiency classification map, a favorable fuel efficiency region (for example, fuel consumption is minimized) in which a favorable fuel efficiency corresponding to the vehicle can be obtained as a desired state based on the relationship between the engine speed of the vehicle 1 and the output (or average effective pressure). ECO range, etc.) and a transient fuel consumption region in which the fuel consumption deteriorates by deviating from the good fuel consumption region are set.

  Although details will be described later, the transient fuel consumption area of the fuel consumption classification map stored in the storage means 9 includes a first transient fuel consumption area on the good fuel consumption area side and a second transient fuel consumption area on the opposite side to the good fuel consumption area side. Is set. In addition, an instruction line in which an instruction line for instructing a shift speed change (upshifting or downshifting) is set in the storage means 9 according to the relationship between the engine rotational speed of the vehicle and the output (or average effective pressure). A map is stored (see FIG. 4C described later).

  Then, the fuel efficiency area map is set by superimposing the fuel efficiency classification map and the instruction line map, and the fuel efficiency area map is stored in the storage means 9 (see FIG. 5 described later). It is also possible to store the fuel efficiency division map and the instruction line map as they are, and execute a process of superimposing them appropriately.

  The control means 8 displays the display mode (details) of the display means 6 when the relationship between the engine rotational speed and the output changes from the good fuel consumption area to the transient fuel consumption area (first transient fuel consumption area, second transient fuel consumption area). As will be described later, for example, changing means 7 for changing blinking, lighting, blinking / lighting color) is provided. The display mode that is changed by the changing means 7 is a display that prompts a shift operation (operation related to shift) in which the driving state changes from the transient fuel consumption region (first transient fuel consumption region, second transient fuel consumption region) to the good fuel consumption region. Yes.

  In the vehicle display device of the present embodiment, the display 6 prompts the operation to the gear position where the fuel consumption is good according to the fuel consumption region map based on the engine rotational speed and the output (or average effective pressure) of the vehicle. Is implemented.

  The control map will be specifically described based on FIG. 4 and FIG.

  FIG. 4 shows an example of a control map. FIG. 4 (a) is a fuel consumption map, FIG. 4 (b) is a fuel consumption classification map, and FIG. 4 (c) is a gear shift instruction line map. FIG. 5 shows an example of the fuel efficiency region map.

  As shown in FIG. 4A, a good range 21 with good fuel efficiency is set according to the relationship between the engine rotational speed of the vehicle and the output (or average effective pressure), and the range gradually becomes better outside the good range 21. Is spreading. And it becomes an area | region where a fuel consumption deteriorates toward the area | region outside the range which becomes favorable.

  Based on the fuel consumption map shown in FIG. 4 (a), a fuel consumption classification map is set as shown in FIG. 4 (b).

  In the fuel consumption classification map, a good fuel consumption region 22 (ECO region: shaded portion) in which good fuel consumption corresponding to the vehicle is obtained is set according to the relationship between the engine rotational speed and the output of the vehicle. And the 1st transition fuel consumption area | region 23 (white part) from which it deviates from the favorable fuel consumption area | region 22 and a fuel consumption worsens is set, and a fuel consumption worsens further on the opposite side of the good fuel consumption area | region 22 of the 1st transition fuel consumption area | region 23. A second transient fuel consumption region 24 (shaded area) is set.

  That is, when the engine speed is on the low speed side, the boundary line between the good fuel efficiency region 22 and the first transient fuel efficiency region 23 is set in a direction in which the output increases as the engine speed increases. . Further, when the engine rotational speed is on the high rotational speed side, the boundary line between the good fuel efficiency region 22 and the first transient fuel efficiency region 23 is set so that the output decreases as the engine rotational speed increases. .

  As a result, the boundary line between the good fuel efficiency region 22 and the first transient fuel efficiency region 23 is set in a mountain shape according to the engine speed. The boundary line between the first transition fuel consumption region 23 and the second transition fuel consumption region 24 is also set in a mountain shape along the boundary line between the good fuel consumption region 22 and the first transition fuel consumption region 23.

  On the other hand, as shown in FIG. 4C, an instruction line map is set according to the relationship between the engine rotational speed of the vehicle and the output (or average effective pressure). (Or downshift) is set.

  That is, the first up instruction line 26 for instructing a shift from the first gear to the second gear is set on the high engine speed side when the current running state changes from the low speed side to the high speed side. Has been. Further, on the side where the engine speed is high, the shift speed from the second speed or higher to the first speed is increased every time or from the second speed to the third speed or higher (for example, from the third speed to the sixth speed). A second up instruction line 27 for instructing a shift is set. In addition, for the second speed or higher, an up instruction line may be set for each number of stages.

  In other words, the higher the speed of rotation, the easier it is for the first display means (display of a shift promotion direction to be described later) to be displayed in the second mode (display when straddling the up instruction line), and upshifting is facilitated. Good fuel consumption can be promoted by preventing the rotational speed from becoming too high.

  On the low engine speed side, when the current running state changes from the high speed side to the low speed side, the speed changes from the sixth speed to the fifth speed or less (for example, from the fifth speed to the second speed). A first down instruction line 28 for instructing a shift is set. Further, a second down instruction line 29 for instructing a shift from the second gear to the first gear is set on the side where the engine speed is low. Similar to the up instruction line, a down instruction line may be set for each number of stages from the sixth speed to the second speed.

  That is, since the first display means (display of a shift promotion direction described later) is more likely to be displayed in the second mode (display when straddling the down instruction line) as the rotation speed is lower, the shift down is more easily promoted. Good fuel consumption can be promoted while preventing engine stall.

  4B and the instruction line map shown in FIG. 4C are overlaid, so that a fuel consumption area map is set and the storage means 9 as shown in FIG. Is remembered.

  As shown in FIG. 5, in the good fuel economy region 22, an idle region 30 (dotted line collection portion) is set in a region where the engine speed is low and the output is low. Based on the fuel consumption area map, whether the speed change operation for improving the fuel efficiency is promoted by downshifting or the speed change operation for improving the fuel efficiency is promoted by upshifting according to a change in the travel state from the point 31 of the current travel state Is set.

  For example, when changing to a region where fuel efficiency deteriorates due to a shift-up (arrow A) or a deceleration state (arrow B), the shift-down is set to be promoted. That is, when the engine speed changes to the low speed side, the speed change operation is set to be urged to the low speed side.

  In addition, when changing to a region where fuel consumption deteriorates due to a downshift (arrow C) or an acceleration state (arrow D), the upshift is set to be promoted. That is, when the engine rotation speed changes to the high rotation speed side, the speed change operation is set to be urged to the high speed stage side.

  Based on the fuel efficiency area map, the relationship between the engine speed and the output is within the area of the good fuel efficiency area 22. The first up instruction line 26, the second up instruction line 27, the first down instruction line 28, and the second down When straddling any of the instruction lines 29, the display mode of the first display means 6a (see FIG. 6) and the second display means 6b (see FIG. 6) is changed.

  For example, when the current driving state changes across the instruction line in the good fuel consumption region 22, the first display means 6a (display of the shift promotion direction) is changed from a non-lighting state to a yellow lighting (first mode). Is done. Furthermore, when the driving state of the vehicle changes from the good fuel consumption region 22 to the first transient fuel consumption region 23, the display of the shift promotion direction is changed from yellow lighting to red lighting (second mode). Further, when the driving state of the vehicle changes from the first transient fuel consumption region 23 to the second transient fuel consumption region 24, even if the display of the shift promotion direction is changed from red lighting to red blinking (third mode). Good.

  That is, since the display mode is changed between when the indicator line is straddled within the good fuel economy region 22 and when the transition is made to the transitional fuel consumption region, the driver is further encouraged to perform a shifting operation, and the good fuel economy is achieved. Formation can be promoted.

  As the display mode, in addition to changing the lighting color, changing the shade of the color, changing the blinking state, or increasing the number of indications (marks) of the acceleration direction (arbitrary shape and Is possible).

  With reference to FIG. 5, the display means 6 will be specifically described based on FIG.

  6 shows a specific example of the first display means 6a and the second display means 6b. FIG. 6 (a) shows a state where no display is made, and FIG. FIG. 6C shows a state within the region, FIG. 6C shows a state where the indicator line is straddled within the region of the good fuel consumption region 22, and FIG. 6D shows a state changed to the region of the first transient fuel consumption region 23.

  As shown in FIG. 6A, when the driving state of the vehicle is in the region of the good fuel consumption region 22 and does not straddle the instruction line, that is, when the vehicle is driven with good fuel consumption, the vehicle fuel consumption is reduced. The ECO lamp 35 (second display means 6b: second lighting means) indicating whether or not it is satisfactory lights up in green. When the output of the vehicle changes without crossing the instruction line, for example, when the vehicle changes to the first transient fuel consumption region 23, the ECO lamp 35 is turned off. At this time, the lighting color of the ECO lamp 35 may be changed to yellow or the like, and the ECO lamp 35 can have an arbitrary shape.

  That is, when the display line of the ECO lamp 35 is changed when the indicator line is straddled within the good fuel consumption region 22, it is possible to further promote the formation of good fuel consumption.

  Next to the ECO lamp 35, an up triangle lamp (Δ) that promotes upshifting (Δ), an up promotion lamp 36 (first display means 6 a: first lighting means), and a down triangle triangle that promotes downshifting ( A down promotion lamp 37 (first display means 6a: first lighting means) is provided. The up promotion lamp 36 and the down promotion lamp 37 are lit yellow or red depending on the situation.

  Since the display means is an ECO lamp 35 having an arbitrary shape, and an up promotion lamp 36 and a down promotion lamp 37 having a shape indicating the shift level, and the display form is changed by changing the lighting state. Thus, the driver's speed change operation can be accurately promoted.

  When the driving state of the vehicle crosses the first up instruction line 26 in the region of the good fuel consumption region 22 (in a state where the ECO lamp 35 is lit in green), for example, as shown in FIG. In addition, the ECO lamp 35 is turned off and the up promotion lamp 36 is lit in yellow. For this reason, it is possible to encourage the driver to shift up by the type and lighting of the lamp, and to promote good fuel consumption.

  When the driving state of the vehicle is changed from the good fuel consumption region 22 to the first transient fuel consumption region 23 from the state in which the up promotion lamp 36 is lit yellow, as shown in FIG. Is changed to red. For this reason, by changing the lighting color of the lamp to red, it is possible to attract the driver's attention and further promote upshifting, and to promote good fuel economy.

  In addition, when the driving state of the vehicle further changes from the first transient fuel consumption region 23 to the second transient fuel consumption region 24 from the state in which the up promotion lamp 36 is lit in red, the up promotion lamp 36 is flashed in red. You may change to In this way, the lamp changes from the lighting state to the blinking state, thereby further attracting the driver's attention and prompting the shift up, thereby promoting the formation of good fuel consumption.

  The promotion of downshifting is performed in the same way. For example, when the driving state of the vehicle crosses the first down instruction line 28 in the region of the good fuel economy region 22 (in a state where the ECO lamp 35 is lit in green), the ECO lamp 35 is turned off. The down promotion lamp 37 is lit in yellow. Moreover, when it changes to the area | region of the 1st transition fuel consumption area | region 23, the down promotion lamp | ramp 37 is changed into red lighting.

  As described above, when the driving state of the vehicle changes from the good fuel consumption region 22 to the region requiring the shift (to the region where the fuel consumption deteriorates), the ECO lamp 35, the up promotion lamp 36, and the down promotion of the display means 6 are displayed. By changing the lighting state of the lamp 37, it is possible to instruct a speed change operation so that the relationship between the engine rotation speed and the output becomes the region of the good fuel consumption region 22.

  An example of the operation of the display means 6 will be specifically described with reference to FIGS.

  During acceleration operation, the engine speed increases and fuel consumption deteriorates. For this reason, a reduction in engine speed is promoted by shifting up, and driving that is advantageous to fuel efficiency is promoted.

  That is, when the vehicle is in the acceleration operation state from the steady traveling at the point 31 in the current traveling state, the relationship between the engine speed and the output is in a state of straddling the first up instruction line 26. Thereby, the up promotion lamp 36 of the display means 6 lights in yellow. When the acceleration operation is continued, the relationship between the engine speed and the output changes to the first transient fuel consumption region 23, and the up promotion lamp 36 is lit red.

  Further, when the gear is shifted up at the point 31 in the current traveling state, the engine rotation speed becomes low, and the relationship between the engine rotation speed and the output crosses the first down instruction line 28. Thereby, the down promotion lamp 37 lights in yellow. Further, when the acceleration operation is performed in this state, the relationship between the engine speed and the output changes to the first transient fuel consumption region 23, and the down promotion lamp 37 is lit in red.

  During the deceleration operation, the engine rotation speed advantageous for fuel consumption is maintained by downshifting, and the continuation of the state in which no fuel is injected is promoted until the idle region 30 where fuel injection is resumed is reached. In other words, when the vehicle travels from the steady travel at the point 31 in the current travel state to the deceleration operation state, the relationship between the engine speed and the output goes across the first down instruction line 28. Thereby, the down promotion lamp 37 lights in yellow.

  On the other hand, when the relationship between the engine rotation speed and the output is in the idle region 30, the ECO lamp 35, the up promotion lamp 36, and the down promotion lamp 37 of the display means 6 are set to the standard state of non-lighting.

  As described above, when the relationship between the engine speed and the output changes from the good fuel efficiency region 22 to the region requiring the shift (to the region where the fuel consumption deteriorates) due to various operating conditions, the ECO of the display unit 6 is changed. It is possible to change the lighting state of the lamp 35, the up promotion lamp 36, and the down promotion lamp 37 as appropriate, and to instruct a shift operation so that the relationship between the engine rotation speed and the output becomes the good fuel economy region 22.

  With reference to FIG. 5, an example of display means in a vehicle equipped with an automatic transmission having a manual shift mode will be described based on FIG.

  FIG. 7 shows an example of display means in a vehicle equipped with an automatic transmission having a manual transmission mode. FIG. 7A shows a state where no display is made, and FIG. FIG. 7C shows a state in the region 22, a state in which the indicator line is straddled in the region of the good fuel consumption region 22, and FIG. 7D shows a state in which the region has changed to the region of the first transient fuel consumption region 23.

  The manual transmission mode of the automatic transmission is a function that can manually change the gear position by a driver's operation at the position of the drive mode (D mode). For example, a vehicle equipped with an automatic transmission having a manual shift mode is provided with the display means 41 shown in FIG. 7A in the combination meter 5 (see FIG. 2). In addition to the display of each shift range PRND, the display means 41 displays the current shift stage (fourth speed stage in the illustrated example) 42 in the manual shift mode.

  In the vicinity of the current gear stage 42, an up-promoting ramp 43 with an upward triangular mark (Δ) for promoting upshifting and a down-promoting ramp 44 with a downward triangular mark (▽) for promoting downshifting are provided. Yes. The up promotion lamp 43 and the down promotion lamp 44 are lit yellow or red depending on the situation.

  When the relationship between the engine rotational speed and the output is within the good fuel economy region 22, the display means 41 is in a state where the current gear stage 42 is lit in green as shown in FIG. The

  When the relationship between the engine rotation speed and the output crosses the first up instruction line 26, the up promotion lamp 43 is lit in yellow as shown in FIG. 7C. From this state, when the relationship between the engine rotational speed and the output changes from the good fuel consumption region 22 to the first transient fuel consumption region 23, the up promotion lamp 43 is lit red as shown in FIG. Changed to Thereby, the speed change operation is promoted.

  The lighting of the down promotion lamp 44 is also changed as appropriate when the first down instruction line is straddled or when the first transition fuel consumption area 23 is changed, and the speed change operation is promoted.

  Thus, the display means 41 is displayed when the relationship between the engine speed and the output changes from the good fuel efficiency region 22 to the region requiring the shift (the region where the fuel consumption deteriorates) during execution of the manual shift mode. The lighting state of the current shift stage 42, the up promotion lamp 43, and the down promotion lamp 44 is appropriately changed, and a shift operation is instructed so that the relationship between the engine speed and the output is in the good fuel economy region 22. it can.

  And since the display for accelerating the shift to instruct upshift, downshift, etc. and the display of the current shift stage are combined, the display of the instruction to accelerate the shift and the current shift stage is confirmed at the same time And there is no fear that the driver will be confused.

  When the relationship between the engine rotational speed and the output is in the idle region 30, the ECO lamp 35, the up promotion lamp 36, and the down promotion lamp 37 of the display means 6 are set to a non-lighting standard state to perform creep running. Become. When the relationship between the engine rotation speed and the output changes to the first transient fuel consumption region 23 due to creep running, the current gear stage 42 may be lit in yellow.

  An example of display means in the automatic transmission mode in a vehicle equipped with an automatic transmission will be described based on FIG.

  FIG. 8 shows an example of display means in a vehicle equipped with an automatic transmission. FIG. 8 (a) shows a state where good fuel consumption is achieved, FIG. 8 (b) shows a state where fuel consumption is expected to deteriorate, 8 (c) is a state in which the fuel consumption tends to deteriorate.

  For example, a vehicle equipped with an automatic transmission is provided with a display means 51 shown in FIG. 8A in the combination meter 5 (see FIG. 2). The shift means P, R, N, and D are displayed on the display means 51. When the relationship between the engine rotation speed and the output is within the range of the state where good fuel consumption is achieved, the display means 51 sets the display of the drive range (D), for example, to be lit in green. .

  When the relationship between the engine rotational speed and the output changes to a state where fuel consumption is expected to deteriorate, the display of the drive range (D) is turned on, for example, in yellow. When the relationship between the engine rotation speed and the output changes to a state where the fuel consumption tends to deteriorate, the display of the drive range (D) is turned on, for example, in red.

  As a result, the driver can perform operations related to gear shifting, such as releasing the accelerator pedal, and can perform driving in a state in which gear shifting is performed in a state in which good fuel consumption is achieved.

  The above-described vehicle display device of the present invention can accurately instruct shift-up and shift-down gear shifts according to driving conditions, and can promote gear shift operations so that good fuel consumption can be obtained. become.

  In the above embodiment, an example in which the lighting color of the display unit is changed stepwise has been described, but the present invention is not limited to this. For example, the lighting color may be gradually changed or the blinking speed may be gradually increased as the driving state of the vehicle moves away from the good fuel efficiency region. Thus, the speed change operation can be promoted more accurately according to the driving state.

  The present invention can be used in the industrial field of vehicle display devices.
