Description

  The present invention relates to a vehicular meter display device capable of individually setting illumination brightness of meters.

  An instrument panel of an automobile is provided with a combination meter that collectively displays meters indicating a driving state of the vehicle, such as a speedometer, a tachometer, a water temperature gauge, a fuel gauge, and a warning light. Each of the meters arranged in this combination meter is illuminated by a light source for illumination or emits light by itself, so that it is a passenger (in many cases, “driver”, and therefore “driver”). To be visually recognized).

  Further, for example, Patent Document 1 (Japanese Patent Laid-Open No. 2001-83913) discloses a technique for alerting the driver by making a message displayed on the combination meter brighter than the display brightness of the tachometer or the like. Yes.

Further, in Patent Document 2 (Japanese Patent Laid-Open No. 2007-132870), the monitor screen provided in the car navigation system is displayed brightly only when there is information to be transmitted to the driver. A technique for reducing power consumption is disclosed.
JP 2001-83913 A JP 2007-132870 A

  However, in the technologies disclosed in Patent Documents 1 and 2 described above, items for providing a brightness difference in display contents are determined in advance, so that the driver can reduce the illumination brightness of the meters disposed in the combination meter. It cannot be adjusted individually.

  In addition, the illumination brightness of the entire combination meter can be switched in stages by operating the brightness adjustment dial. However, it cannot be switched individually for each meter, and there is a problem that the usability is poor.

  That is, there are meters that need not be watched by some drivers and meters that need to be watched. For example, when driving on a circuit in a commercial vehicle, the tachometer is watched, but the speedometer is not required.

  There is an inconvenience that a meter that does not need to be watched is displayed with the same illumination brightness as that of the meter that is to be watched. Furthermore, depending on the position of the meters, there are cases where the driver feels dark and bright, but since this sensation varies among individuals, it is difficult to set it uniformly.

  In view of the above circumstances, an object of the present invention is to provide an easy-to-use vehicle meter display device that can individually set illumination brightness of meters.

  In order to achieve the above object, the present invention provides a light source unit for illumination having a plurality of meters disposed on an instrument panel of a vehicle and a light source for illuminating the meters, and a control for varying the illumination brightness of the light source for illumination. In the vehicular meter display device, the illumination light source unit is provided with a light source for each meter or for a predetermined group of meters, and the control unit is divided for the meter or for a predetermined period. And an illumination luminance setting means for variably setting the illumination luminance of the light source that illuminates the meter or the meter group selected from the meter group.

  According to the present invention, it is possible to variably set the illumination brightness of the light source that illuminates a selected meter group or a predetermined group of meter groups from a plurality of meters or meter groups arranged on the instrument panel. The illumination brightness of each meter can be variably set according to the driver's preference, and it is easy to use.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a front view of a combination meter disposed on a vehicle instrument panel.

  This combination meter (hereinafter abbreviated as “combimeter”) 3 is disposed at a position on the instrument panel disposed at the front of the vehicle interior that is easily visible to the driver. Meters for displaying information required by the driver are arranged on the combination meter 3 in a predetermined manner.

  In the present embodiment, as meters, a tachometer 3a indicating the engine speed disposed on the left and right near the center, a speedometer 3b displaying the vehicle speed, and a water temperature disposed on the left side of the tachometer 3a to display the cooling water temperature. An abnormality occurred in total 3c, a fuel gauge 3d that is disposed on the right side of the speedometer 3b and displays the remaining amount of fuel, and a gear stage display 3e that is disposed in the center and displays the current gear stage. A warning lamp 3f that lights or flashes in some cases, a multi-information display (hereinafter abbreviated as “MID”) 12 disposed below the tachometer 3a, and a fuel consumption meter 13 disposed below the speedometer 3b. Have. Although not shown, the combimeter 3 is provided with various indicators other than these that indicate the state of the vehicle. In the present embodiment, the meters including the indicators are referred to as meters.

  The gear stage display unit 3e and the MID 12 are display devices using liquid crystal or the like, the gear stage display unit 3e is a segment display device, and the MID 12 is a dot matrix display device. In addition, the MID 12 displays a trip meter indicating the section travel distance and an odometer indicating the total travel distance, and can display information such as fuel consumption and current time by switching display contents.

  The fuel consumption meter 13 is an indicator for economical driving based on the difference between the instantaneous fuel consumption and the trip average fuel consumption. The neutral position indicates the trip average fuel consumption [Km / L], and this trip average fuel consumption [Km / L If the instantaneous fuel consumption [Km / L] is higher than the average fuel consumption [Km / L], the indicator 13a moves in the plus (+) direction according to the deviation, and conversely, the instantaneous fuel consumption [Km / L] is higher than the trip average fuel consumption [Km / L]. Is low, the pointer 13a swings in the minus (-) direction.

  Each of these meters 3a to 3f, 13 and MID 12 is controlled based on a signal from a meter control device (meter_ECU) 21 as a control unit, as shown in FIG. This meter_ECU 21 controls the entire combination meter 3 and is mainly composed of a computer such as a microcomputer, and has a well-known non-volatile memory such as a CPU, ROM, RAM, and EEPROM. Various programs executed by the CPU, fixed data, and the like are stored in the ROM.

  An illumination changeover switch 10, a brightness adjustment dial switch 11, and the like are connected to the input side of the meter_ECU 21. Also connected to the output side are a combination meter drive unit 26 for driving the meters 3a to 3f, 13, a MID drive unit 27 for driving the MID 12, a fuel consumption meter drive unit 28 for driving the fuel consumption meter 13, and an illumination drive unit 29. Has been. Further, an illumination light source unit 5 that individually illuminates the meters 3 a to 3 f and 13 and the MID 12 is connected to the illumination drive unit 29. The meter_ECU 21 has a function as illumination luminance setting means for individually setting the illumination luminance of the light sources 5a to 5h (described later) of the illumination light source unit 5 (details will be described later).

  The illumination changeover switch 10 selects whether the illumination brightness of the entire combination meter 3 is uniform or only the registered meters are highlighted (the highlighted display of the meters will be described later). The brightness adjustment dial switch 11 variably sets a base brightness that becomes a reference when setting the illumination brightness of the combination meter 3 in a stepwise manner. The meter_ECU 21 outputs a step-like signal output from the brightness adjustment dial 11. Accordingly, the luminance level is set to six levels L1 to L6 from the low luminance to the high luminance side (see FIG. 5). Note that the base luminance uniformly changes the illumination luminance of the entire combination meter 3.

  The meter_ECU 21 is connected to an engine control device (E / G_ECU) 22, a transmission control device (T / M_ECU) 23, and a navigation control device as a control unit via an in-vehicle communication line 16 such as CAN (Controller Area Network) communication. (Navi_ECU) 24 is connected to each control device such as 24 so as to be able to communicate with each other. Each of the ECUs 22 to 24 is configured mainly by a computer such as a microcomputer, like the meter_ECU 21 described above, and includes a well-known CPU, ROM, RAM, and nonvolatile memory such as an EEPROM. Various programs executed by the CPU, fixed data, and the like are stored in the ROM.

  The E / G_ECU 22 controls the entire engine, such as fuel injection control, ignition timing control, and throttle control when an electronic control throttle device is mounted. The T / M_ECU 23 controls the shift of the automatic transmission. For example, when the select lever (not shown) is set in the D range, the shift control is performed according to a preset shift pattern. . The navigation_ECU 24 is provided in a well-known car navigation system, and detects the position of the vehicle based on position data obtained from a GPS satellite or the like and calculates a guide route to the destination. And the present location and taxiway of the own vehicle are displayed on the map data on the display 4. The display 4 also serves as a touch panel, and the illumination brightness of an illumination light source unit 5 to be described later can be set on the display 4. The setting of the illumination brightness of the illumination light source unit 5 will be described later.

  The illumination light source unit 5 connected to the illumination drive unit 29 described above is disposed on the back side of the panel surface on which the meters of the combimeter 3 are displayed. The illumination light source unit 5 includes light sources 5a to 5h that individually illuminate each of the meters 3a to 3f and 13 and the MID 12. The light sources 5a to 5f that illuminate the meters 3a to 3d, 3f, and 13 are, for example, LEDs and EL (Electro-Luminescence), and the shift stage display unit 3e and the light sources 5g and 5h of the MID 12 are liquid crystals. In the case of a display device, it is a backlight. If it is a self-luminous type such as an organic EL (Electro-Luminescence), it emits light directly.

  Further, when the combination meter 3 employed in the present embodiment is a so-called black face meter, when the ignition switch is OFF, the combination meter 3 is in a black face state. When the ignition switch is turned ON, the illumination light source unit 5 Illumination light emitted from the light sources 5a to 5g provided is transmitted through a dial and hands formed of a light transmitting material, and the meters 3a to 3f and 13 are raised. Therefore, in the black face meter, the illumination light source unit 5 is always turned on from when the ignition switch is turned on until it is turned off. Further, in the case of a so-called normal meter in which the combination meter 3 reflects and displays the illumination light from the illumination light source unit 5, illumination light from the illumination light source unit 5 is provided on the outer periphery of each of the meters 3 a to 3 f and 13. The light is reflected on the reflecting member and irradiated on the dial or the hands to display them. In this case, the illumination light source unit 5 is turned on / off in conjunction with a lighting switch that performs a lighting operation of a lighting device represented by a headlamp. In the following, a case where a black face meter is employed as the combination meter 3 will be described as an example.

  The illumination brightness of the light sources 5a to 5g for illuminating the meters 3a to 3f and 13 and the light source 5h provided in the MID 12 can be individually set. The illumination brightness is set on the display 4 connected to the navigation_ECU 24. The setting of the illumination brightness is performed by a program of the navigation_ECU 24, and the data is stored in the meter_ECU 21 through the in-vehicle communication line 16. Therefore, this navigation_ECU 24 becomes the luminance setting means of the present invention. The illumination brightness may be set according to a program stored in the meter_ECU 21. In this case, this meter_ECU 21 serves as the luminance setting means of the present invention.

  Next, the setting of the illumination brightness of each of the light sources 5a to 5h provided in the illumination light source unit 5 will be described. The illumination brightness is set according to a program stored in the navigation_ECU 24 (or meter_ECU 21).

  First, the meter brightness adjustment item is selected from the menu displayed on the display 4. Then, as shown in FIG. 3, a screen for selecting meters to be highlighted is displayed on the display 4. The driver selects one or more desired meters from the displayed meters, and presses the confirmation button 4a. Then, the selected meters are stored in the nonvolatile memory of the meter_ECU 21. For example, when the driver selects and confirms the tachometer 3a from the screen for selecting the meters shown in FIG. 3, as shown in FIG. 5, the lighting brightness of the meters 3b to 3f, 13 other than the tachometer 3a is adjusted. The base luminance set by the dial switch 11 is set, and only the illumination luminance of the tachometer 3a becomes the illumination luminance on the high luminance side by the luminance difference a with respect to the base luminance. This base luminance is a reference when setting the illumination luminance of each of the light sources 5a to 5h.

  Therefore, as shown in FIG. 5B, when the brightness adjustment dial switch 11 is operated to increase the base brightness, the brightness difference a between the tachometer 3a illumination brightness and the other meters 3b to 3f, 13 becomes constant. In the held state, the illumination brightness of the entire combimeter 3 is uniformly increased.

  Next, the procedure for highlighting the meters selected by the driver will be described according to the highlighting setting routine shown in FIG. This routine is performed in the meter_ECU 21.

  First, it is checked in step S1 whether the illumination changeover switch 10 is ON. If it is ON, it is determined that highlighting is selected, and the process proceeds to step S2. If it is OFF, it is determined that uniform illumination brightness is selected, and the process jumps to step S4.

  In step S2, it is checked whether or not the meters to be highlighted are registered. If registered, the process proceeds to step S3. If not registered, the process proceeds to step S4.

  When the process proceeds to step S3, the already registered meters are highlighted with the illumination brightness on the higher brightness side by the brightness difference a (see FIG. 5) than the base brightness, and the routine is exited. When the process proceeds from step S1 or S2 to step S4, the entire meter is displayed with the same base luminance and the routine is exited.

  As described above, in the present embodiment, the driver displays the meters (the tachometer 3a in the present embodiment) to be highlighted according to his / her preference so that the brightness difference a is brighter than the other meters. Therefore, only the information desired to be obtained from the combination meter 3 can be viewed in an instant, which is easy to use.

  Therefore, a driver driving a commercial vehicle on a circuit, when driving on a general road, turns off the illumination changeover switch 10 to display the entire combimeter 3 with the same illumination brightness, and when driving on a circuit, By turning on the changeover switch 10 and brightening only the tachometer 3a registered as a preliminarily highlighted meter, visibility during circuit running can be ensured.

[Second Embodiment]
6 to 8 show a second embodiment of the present invention. In the first embodiment described above, when the driver selects a meter to be highlighted, the selected meter is illuminated on the higher luminance side by a luminance difference a than the base luminance that is the illumination luminance of the other meters. Although the illumination is performed with the brightness, in this embodiment, it is possible to select the meters that are desired to be displayed in a weak tone, and the illumination brightness of the selected meters is the illumination brightness on the lower brightness side by the brightness difference a than the base brightness. It is intended to be displayed.

  Accordingly, when an item for adjusting the meter brightness is selected from the menu displayed on the display 4, a screen for selecting meters to be displayed in a weak tone is displayed on the display 4 as shown in FIG. The driver selects one or more desired meters from the displayed meters, and presses the confirmation button 4a. Then, the selected meters are stored in the nonvolatile memory of the meter_ECU 21.

  For example, when the driver selects the tachometer 3a from the screen for selecting meters shown in FIG. 6, as shown in FIG. 8, the illumination brightness of the tachometer 3a is set to be darker by the brightness difference a than the base brightness. In this case, the illumination brightness of the other meters 3b to 3f, 13 is set to the base brightness set by the brightness adjustment dial switch 11.

  Therefore, as shown in FIG. 4B, when the base brightness is increased by operating the brightness adjustment dial switch 11, the illumination difference a between the tachometer 3a and the other meters 3b to 3f, 13 becomes constant. In the held state, the illumination brightness of the entire combimeter 3 is uniformly increased.

  Next, a procedure for displaying in a weak tone the meters selected by the driver will be described according to a weak tone display setting routine shown in FIG. This routine is performed in the meter_ECU 21.

  First, in step S11, it is checked whether or not the illumination changeover switch 10 is ON. If ON weak tone display is selected, the process proceeds to step S12. If OFF, the process jumps to step S14.

  When the process proceeds to step S12, it is checked whether or not the meters to be displayed in weak gradation are already registered. If they have been registered, the process proceeds to step S13, and if they are not registered, the process proceeds to step S14.

  When the process proceeds to step S13, the already registered meters are displayed with a weak tone with a luminance difference a (see FIG. 8) lower than the base luminance, and the routine is exited. When the process proceeds from step S11 or S12 to step S14, the entire meter is displayed with the same base luminance, and the routine is exited.

  As described above, in this embodiment, the driver displays the meters (tachometer 3a in the present embodiment) that he / she wants to display in a weak tone in accordance with his / her preference so that the brightness difference a is darker than other meters. Therefore, it is possible to narrow down only the information that is desired to be obtained by reducing the illumination brightness for information that is not desired to be obtained from the combination meter 3 so that the visibility is improved and the usability is good.

[Third Embodiment]
9 and 10 show a third embodiment of the present invention. In the first and second embodiments described above, the luminance difference a when highlighting or weakly displaying meters is set based on the base luminance, but in this embodiment, the illumination luminance of the selected meters is set. The luminance difference a with the illumination luminance of the meters not selected is kept constant, and the distribution ratio can be variably set.

  That is, for example, as shown in FIG. 3 of the first embodiment, the driver selects a desired meter (for example, tachometer 3a) from the meters to be highlighted displayed on the display 4 and confirms it. When the button 4a is pressed, the navigation_ECU 24 causes the display 4 to display a screen for setting the illumination luminance distribution ratio shown in FIG. The driver operates the level setting buttons 4b and 4c displayed on this screen to set the distribution ratio of the illumination luminance, and presses the confirmation button 4a. Then, the set distribution ratio of the illumination luminance is stored in the nonvolatile memory of the meter_ECU 21.

  As shown in FIG. 10, for example, when the tachometer 3a is selected as a highlighting meter, as shown in FIG. 10A, the distribution ratio of the illumination brightness is 100 [%], and the tachometer 3a is more than the base brightness. Is displayed brightly by the luminance difference a, and meters not selected are displayed at the base luminance. Further, as shown in FIG. 5B, when the distribution ratio of illumination luminance is set to 50 [%], the tachometer 3a becomes brighter by 50 [%] of the luminance difference a with respect to the base luminance, In addition, other meters are set to be darker by 50 [%] of the luminance difference a with reference to the base luminance. Similarly, as shown in FIG. 5C, when the blending ratio of the illumination brightness is 0 [%], the illumination brightness of the tachometer 3a is set to the base brightness, and the illumination brightness of other meters is the brightness difference a. Only set darker.

  Therefore, when it is determined that the illumination changeover switch 10 is ON in step S1 of the highlighting setting routine shown in FIG. 4 of the first embodiment, in step S3, the illumination luminance according to the illumination luminance distribution ratio set by the driver is used. Meters are displayed.

  In addition, although this embodiment demonstrated as a modification of 1st Embodiment, it can also be applied as a modification of 2nd Embodiment. That is, in this case, when the meters (for example, the tachometer 3a) to be displayed in a weak tone are selected on the display 4 shown in FIG. 6, when the illumination luminance distribution ratio is set on the screen shown in FIG. 9, the display mode shown in FIG. On the contrary, the state shown in FIG. 10C is obtained at 100 [%], and the state shown in FIG.

  As described above, in the present embodiment, the distribution ratio of illumination luminance between meters selected for highlighting or weak gradation display and meters not selected can be variably set, so that the driver is dazzling or dark Meters can be selected individually, and the distribution ratio of their illumination brightness can be set. As a result, it is possible to arbitrarily set the illumination brightness according to the driver's preference by adjusting the distribution ratio of the illumination brightness to the meters and adjusting the brightness of the entire combination meter 3 by operating the brightness adjustment dial switch 11. And visibility can be further improved.

[Fourth Embodiment]
FIG. 11 shows a fourth embodiment of the present invention. The present embodiment is an application example of the first to third embodiments described above. In the first to third embodiments, only one driver adjusts the illumination brightness for each meter. However, in the present embodiment, when a plurality of drivers drive one vehicle, driving is performed. The illumination brightness of the meters can be individually set and registered for each person.

  That is, the door locking / unlocking control device (door locking / unlocking_ECU) 31 is connected to the other ECUs 21 to 24 through the in-vehicle communication line 16 so as to be able to communicate with each other. The door locking / unlocking_ECU 31 has a known CPU, ROM, RAM, and nonvolatile memory such as an EEPROM, and the like, and various data executed by the CPU and fixed data such as an ID code are stored in the ROM. .

  The portable device 33 includes a signal control unit 34 and a transmission / reception unit 35 having a function as a so-called smart key. The signal control unit 34 stores an ID code unique to the portable device 33 and comprehensively controls each unit of the portable device 33. In addition, the transmission / reception unit 35 receives various request signals transmitted from the transmission / reception unit 32 provided in the door locking / unlocking_ECU 31, and also transmits an ACK signal (acknowledgment signal) to the activation request signal to the transmission / reception unit 32. Then, an ID code unique to the portable device 33 is wirelessly transmitted.

  When the signal control unit 34 of the portable device 33 receives the ID request signal transmitted from the transmission / reception unit 32 provided in the door locking / unlocking_ECU 31 via the transmission / reception unit 35, the signal control unit 34 receives the ID code via the transmission / reception unit 35. Send.

  When the driver carrying the portable device 33 enters the transmission / reception area of the transmission / reception unit 32 provided in the door locking / unlocking_ECU 31, the transmission / reception unit 35 of the portable device 33 is transmitted / received provided in the door locking / unlocking_ECU 31. A request signal from the unit 32 is received, and a response signal including a unique ID code is transmitted from the transmission / reception unit 35 to the transmission / reception unit 32 of the door locking / unlocking_ECU 31.

  Then, the door lock / unlock_ECU 31 compares the ID code included in the response signal received by the transmission / reception unit 32 with the code recorded in its own memory, and determines whether the portable device 33 is for the vehicle. If the portable device 33 is for the vehicle, an unlock signal is output to an actuator drive circuit (not shown) to unlock the door.

  At this time, this ID code is transmitted to the meter_ECU 21, and it is checked whether or not the ID code is registered. If the driver holding the portable device 33 has already registered the meter to be highlighted or displayed in weakness in any of the first to third embodiments described above, the driver is registered. Data is read out.

  That is, the meter_ECU 21 executes the above-described highlight display setting routine of FIG. 4 or the weak tone display setting routine of FIG. 7, and the meters registered corresponding to the ID code in step S3 or step S13 are displayed. The routine is exited with the highlighting or weak gradation display.

  Thus, in this embodiment, even if a plurality of drivers use one vehicle, the illumination brightness of meters is registered for each driver holding the portable device 33. For example, two portable devices 33 are provided, and one portable device 33 can register settings for highlighting the tachometer 3a, and the other portable device 33 can register settings for highlighting the speedometer 3b. As a result, since the illumination brightness of the meters is switched according to the preference of each driver holding the portable device 33, high convenience can be obtained.

  The present invention is not limited to the above-described embodiments. For example, the meters are divided into predetermined groups, and the illumination luminance is highlighted or displayed in a weak tone for each of the divided meter groups. Also good. In this case, the light source of the illuminating light source unit 5 may be arranged for each divided meter group.
