The present invention relates to a vehicle instrument having a mileage display for digitally displaying a mileage.

Conventional vehicle instrument has an indicator, and the necessary vehicle information is delivered to the driver by the lighting of the indicator.

Such an indicator forms a symbol mark by printing on a transparent resin (lens), and displays necessary vehicle information by lighting a light emitting element such as an LED on the back.

In addition, one indicator displays one vehicle information.

In addition, a display having a mileage display portion that displays a numerical value (digital display) of a conventional indicator and a mileage, and simply replaces the mileage display content (display characters) in the mileage display portion, the same as the display content of the indicator Some display contents were displayed (for example, Japanese Patent Laid-Open No. 2003-166857).

In the vehicle instrument that delivers the necessary vehicle information due to the indicator lighting to the driver as in the former case, a light emitting element having the required number of information (symbol mark number) is required, and thus the cost was required.

In addition, the indicator is turned on only when it is necessary to inform the information, and is usually not displayed in the design of the vehicle instrument (the area that the passenger can see while riding).

However, even if it is not normally displayed, it is necessary to secure such a space, which is a design limitation of the design part in a vehicle instrument.

SUMMARY OF THE INVENTION In view of the above points, an object of the present invention is to provide a vehicle instrument which can reduce the quantity of light emitting elements in comparison with a conventional vehicle instrument having a mileage indicator and an indicator different from the latter vehicle instrument. .

In order to achieve the above object, the invention described in claim 1 has a control unit for controlling the mileage display unit, and displays the mileage and the mileage and other types of information in the mileage display unit, and further, It is characterized by displaying different types of information with different distances.

Therefore, the conventional vehicle instrument can display various types of information displayed by the indicator on the mileage display unit, and the number of light emitting elements required for the indicator display as compared to the conventional vehicle instrument in which one indicator displays one information. Can be reduced.

As a result, cost reduction of the vehicle instrument and space saving of the indicator unit of the vehicle instrument can be achieved.

In the present invention, the travel distance and the travel distance and different kinds of information are displayed in different colors.

Therefore, when compared to a vehicle instrument that simply changes the characters displayed on the mileage display part and displays other information, the mileage indication is different from the mileage and Information can be easily recognized.

For example, by changing the color of the text or the background color of the text, it is possible to display information display of different types of travel distances and travel distances in different types of colors.

As a method of displaying in different kinds of colors, for example, as described in claim 4, when displaying the driving distance, the light source illuminating the display element from the back is turned off to display the driving distance and other kinds of information. In this case, a method of lighting the light source can be adopted.

Otherwise, for example, as described in claim 5, a method of changing the color of the light source illuminating the display element from the back can be employed.

In addition, as indicated in, for example, claim 2, the abnormality content of the vehicle can be displayed as a kind of information different from the traveling distance.

In addition, as indicated in claim 3, when displaying the abnormal content on the mileage display part, a character or symbol mark 21 indicating a warning is displayed in an area different from the area 10 displaying the abnormal content on the mileage display part. It is also possible to display.

In the invention described in claim 6, the control unit has a control unit for controlling the mileage display unit, and the mileage and mileage abnormalities are replaced by the control unit so as to be displayed in the same area in the mileage display unit, and the abnormal contents of the vehicle can be displayed. Characteristic or symbol mark 21 indicating a warning is displayed in the area 10 and the other area which display abnormality in the mileage display part at the time.

Accordingly, together with the invention described in claim 1, the number of light emitting elements required for the indicator display can be reduced as compared with the conventional vehicle instrument in which one indicator displays one information.

As a result, cost reduction of the vehicle instrument and space saving of the indicator portion can be achieved at the design portion of the vehicle instrument.

In addition, in the present invention, when displaying the abnormal contents of the vehicle, a character or a symbol mark indicating a warning is displayed in a region different from the region displaying the abnormal contents in the display unit.

This makes it easier for the driver to change the vehicle from the display of the mileage to the display of the abnormality of the vehicle, compared to a vehicle instrument that simply changes the text displayed on the mileage display to display information. Can be recognized.

In the invention described in claim 7, the vehicle has a display unit 31 for displaying a character or a symbol mark representing the display content, the display unit has a control unit for controlling the display unit, and the control unit lights up the display unit. It is characterized in that a plurality of display contents can be discriminated by changing the method.

Accordingly, since a plurality of types of information can be displayed on one display unit (indicator), the number of light emitting elements required for indicator display can be reduced as compared with a conventional vehicle instrument in which one information is displayed on one indicator.

As a result, cost reduction of the vehicle gauge and space saving of the indicator part in the design of the vehicle gauge can be achieved.

In addition, the code | symbol in the parentheses of said each means shows the correspondence with the specific means described in embodiment described later.

First Embodiment

1 is a front view of a vehicle gauge according to a first embodiment of the present invention.

Such a vehicle instrument is provided, for example, in the indie panel of a passenger car.

This vehicle instrument is equipped with a speed meter (speedometer) 1, an od, and a trip (total travel distance and section travel distance) display portion 2.

The speed meter 1 is an analog display of the vehicle speed by the scale plate 4 and the instructions 5 exposed at the opening of the plate 3.

2 and 3 (a) and (b) show an enlarged view of the od and the trip display unit 2 in the drawing, and FIG. 4 shows a perspective view when the od and the trip display unit 2 are disassembled.

The odd and trip display sections 2 have a liquid crystal display section 10 formed from the liquid crystal display 12 in a part of the display region as shown in FIG. 2.

As shown in FIG. 4, the electrode and trip display unit 2 overlaps the lens 11, the liquid crystal display 12 as a display element, and a PCB (printed wiring board) 13 having a backlight 14 on the surface. It is composed.

Here, the lens 11 is made of a light-transmissive material, for example, a transparent resin, and is printed in black with a non-light-transmissive material.

The backlight 14 is, for example, a red backlight 14a and a white backlight 14b.

These backlights 14a and 14b are controlled so that one or both of them are turned on.

The liquid crystal display 12, for example, sandwiches a liquid crystal between two transparent substrates, and controls the transmission and impermeability of light by causing an liquid crystal between the substrates to respond by applying an electric field between the two substrates. To replace the display.

The display method of the liquid crystal display 12 is a segment method, and the thin and long display units are arranged in about six rows in eight characters.

The liquid crystal display 12 is a commonly known positive type, and the numeral 12a is displayed by light passing through the background 12b.

In addition, the background of the liquid crystal display 12 may be replaced with a reflective type when the display form is bright and a transmissive type when the display form is dark.

That is, when it is bright, the surrounding brightness is reflected, and when it is dark, the background 12b is brightened by illuminating the backlight 14b to display black characters.

The odd and trip display unit 2 is connected to a control unit not shown in the drawing, and the display method, the display contents, and the display replacement are controlled by the control unit.

Such a control part is comprised by a microcomputer, for example.

The control unit has an input terminal, and a vehicle speed sensor or an abnormality detection sensor is connected to the input terminal.

The abnormality detection sensor detects, for example, an abnormality in engine control or an abnormality in power steering.

In the odd and trip display unit 2 configured as described above, the od or trip trip is digitally displayed on the liquid crystal display unit 10 by the control unit according to the signal of the vehicle speed sensor, as shown in FIG. 2.

On the other hand, when any abnormality occurs in the passenger car, as shown in Figs. 3A and 3B, the display on the liquid crystal display unit 10 causes errors from the display and the trip display by the control unit in accordance with the signal of the abnormality detection sensor. It is replaced by a code display.

At this time, the red backlight 14a is turned on, and the color of the background 12b of the liquid crystal display 10 becomes a color different from that of the display of the odd and trip displays.

The abnormal mode is displayed on the odd and trip display sections 2 in this way.

Such abnormal mode display is described in a manual such as a vehicle instruction manual.

Based on this, the driver can take the necessary response.

Specifically, as indicated by (a) and (b) of FIG. 3, [Error1] or [Error2] is displayed on the red background 12b on the liquid crystal display 10 by the segment displaying the travel distance.

This color change of the background 12b is performed as follows.

When it is bright during the day or when it is normal (travel distance display), the backlights 14a and 14b turn off, and when an abnormality occurs, the red backlight 14a is turned on.

On the other hand, when it is dark at night, the white backlight 14b is turned on during normal operation, and when the abnormality occurs, the red backlight 14b is turned on.

When the red backlight 14a is turned on, the white backlight 14b is turned on or turned off.

In this way, the display color at the time of abnormal mode display is changed during the odd and trip display.

[Error1] here means an error of EFI (engine control), for example, and [Error2] means an error of EPS (power steering), for example.

Therefore, when such an indication appears on the odd or trip display 2, the driver brings the vehicle to the dealer and checks the EFI or EPS.

The abnormal mode content displayed on the liquid crystal display unit 10 is not limited to the above-described EFI and EPS, but may be other abnormal content.

In addition, the display type at the time of abnormality can display not only [Error1] [Error2] but also the number which changed, such as [Error3] [Error4].

Therefore, it is also possible to display three or more abnormal contents in the odd and trip display section 2.

As described above, in the present embodiment, when an error occurs in the vehicle, [Error1], [Error2], etc. are displayed in place of the od and the trip display in the od and the trip display unit 2.

The contents of [Error1] and [Error2], etc., are contents displayed on a display section composed of characters, symbol marks, and the like as described in the background art section above.

Therefore, compared with the conventional vehicle instrument which displayed abnormal contents in the display part which consists of letters, symbol marks, etc., the number of display parts which consist of letters, symbol marks, etc. can be reduced, and the number of light emitting elements used for a display part can be reduced. .

As a result, according to this embodiment, the cost for a vehicle instrument can be reduced compared with the conventional one, and the energy saving of the injector part in the design part of a vehicle instrument can be aimed at.

In the present embodiment, when [Error1] and [Error2] are displayed on the odd and trip display sections 2, the red backlight 14a is turned on when the white backlight 14b does not light when it is bright. In addition, when it is dark, the color of the background 12b is changed by changing the color of the white backlight 14b.

If simply replacing [Error1] and [Error2] in the odd and trip display portions, the driver may not easily feel the display of [Error1] and [Error2], and there may be a delay in feeling that an abnormality has occurred in the vehicle.

In contrast, in the present embodiment, when displaying [Error1] and [Error2] to change the color of the background 12b, the driver can immediately recognize that an abnormality has occurred in the vehicle.

<2nd embodiment>

In FIG. 5A and FIG. 5B, the odd and trip display sections 2 of the second embodiment are described.

In the first embodiment, when an error occurs in the vehicle, the case where [Error1] or the like is displayed by changing the color of the background 12b has been described. Instead of changing the color of the background 12b, the same manner as in the present embodiment is performed. It is possible to light up the master warning indicator 21.

 In the vehicle instrument of the present embodiment, the master warning indicator 21 is provided in the peripheral region of the liquid crystal display unit 10 among the odd and trip display units 2, and there is no red backlight 14a in the backlight 14. Only the white backlight 14b is different from the first embodiment.

The other components are the same as those for the vehicle instrument shown in Figs.

The master warping indicator 21 is for warning that an abnormality has occurred.

This is a light-transmissive material on the lens 11 is black printed in the shape of the symbol mark, not shown in the drawing.

For example, a symbol mark is displayed by illuminating behind the lens 11 with a red backlight (light source).

Usually, as shown in FIG. 2, an order and a trip are displayed on the order and trip display part 2. As shown in FIG.

On the other hand, when any abnormality occurs in the passenger car, as indicated in Figs. 5A and 5B, [Error1] or [Error2] is displayed on the liquid crystal display unit 10 as in the first embodiment.

At this time, the master warning indicator 21 lights up red in the peripheral region of the liquid crystal display 10 among the odd and trip display units 2 at the same time.

In addition, since the master warning indicator 21 does not light in a normal state (odd and trip display), it is the same color as the lens 11 (black color), but lights up in red when an abnormality occurs.

In addition, the color of the background 12b is the same color as a normal color.

In the present embodiment, the driver is urged to display the master warning indicator 21 in the area different from the liquid crystal display unit 10 in the odd and trip display units 2.

Even if it does so, it has the same effect as 1st Embodiment.

In addition, in this embodiment, when an abnormality has occurred, the case where the color of the background 12b of the liquid crystal display part 10 is the same index as a normal color was demonstrated, but the color of the background 12b differs from a normal color. It is also possible to write in color.

That is, it is also possible to combine 1st Embodiment and 2nd Embodiment.

Third Embodiment

In FIG. 6A and FIG. 6B, the odd and trip display sections 2 of the second embodiment are described.

In the first and second embodiments, when an error occurs in the vehicle, the od and the trip display unit 2 replace the od and the trip display to display [Error1] and the like. As indicated in, it is possible to display characters about the contents, unless [Error1].

That is, as shown in (a) and (b) of FIG. 6, when an abnormality occurs in the vehicle, the liquid crystal display 10 can also be expressed as [ABS] or [EPS] by the segment.

Therefore, a passenger such as a driver can recognize in which part of the vehicle an abnormality occurs even without looking at a reference book such as a manual.

<4th embodiment>

The front view of the vehicle gauge in 4th Embodiment is shown in FIG.

In addition, among the structural parts of the vehicle gauge in FIG. 7, the same code | symbol may be attached | subjected to the same structural part as the structural part of the vehicle gauge of FIG.

In the vehicle instrument of this embodiment, the indicator part 31 which consists of several indicator 31a, 31b, 31c, 31d, 31e, 31f is formed in the area | region below the speed meter 1 in the board | plate 3.

Each of the indicators 31a to 31f is printed with a letter or a symbol mark on a lens (transparent resin), and the display content is displayed by illuminating the lens behind a light emitting element such as an LED which is not shown in the drawing.

Moreover, the vehicle instrument has a control part which is not shown in the figure.

In this control part, various detection sensors are connected, and the indicator part 31 lights up by the control part according to the signal of this detection sensor.

8 and 9 show enlarged views of the indicators 31c and 31d which are one of the indicator parts 31.

The indicator 31c shown in Fig. 8 is master warning and can change the lighting method.

That is, the lighting and blinking can be replaced.

In addition, in the present specification, it means a state in which the lighting and the illumination is continuous, and blinking means a state that the lighting is turned on or off.

On the other hand, the indicator 31d shown in FIG. 9 is a common warning of the brake system, and this also enables the lighting method to be changed.

In the indicator 31d, in addition to the symbol mark, the characters &quot; lighting is parked &quot; and &quot; flashing is insufficient brake &quot; are also recorded.

Moreover, in the vehicle instrument of this embodiment, when an abnormality arises in a vehicle, a control part lights the indicator part 31 according to the signal from various detection sensors.

At this time, in the indicator 31c shown in FIG. 8, for example, the indicator lights up when the EFI is larger than or equal to EFI and blinks when the EPS is larger than the EFI.

In this case, since the contents indicating the lighting and blinking of the driver 31c can be known by reference books such as manuals, the abnormal contents can be confirmed.

On the other hand, in the indicator 31d shown in Fig. 9, for example, the indicator lights up when parking and flashes when the brake fluid is insufficient.

Since the lighting method is already displayed on the indicator 31d differently (lighting and blinking), the driver can check the abnormal contents without looking at the reference book.

In the present embodiment, a plurality of types of information contents are displayed by one indicator by allowing the control unit to change the lighting method of the indicator unit 31 in accordance with the display contents.

Accordingly, the number of indicators consisting of letters and symbol marks can be reduced, and the number of light emitting elements used in the indicators can be reduced, compared to the conventional vehicle instrument displaying abnormality by an indicator consisting of letters and symbol marks.

As a result, according to this embodiment, the cost of a vehicle gauge can be reduced compared with the conventional thing, and the space saving of the indicator part in the design part in a vehicle gauge can be aimed at.

However, in a conventional vehicle instrument, two pieces of information are known to the driver in one indicator.

For example, in a recognizer indicating common warning of the brake system, the indicator lights up in accordance with the parking brake when parking, and the recognizer lights up even when the brake oil is reduced.

As such, there was only one type of indicator display in the past. When the indicator lights up, it means both parking and lack of brake oil.

On the other hand, according to this embodiment, since the lighting method of the indicator part 31 is changed according to display content, a driver can confirm a display content immediately compared with the former.

<Other embodiment>

 In the first, second, and third embodiments, not only the positive type generally referred to as the liquid crystal display portion 12, but also the negative type liquid crystal display 12 can be used.

The negative type means that light is transmitted through the letter 12a, and light is not transmitted through the background 12b so that the letter 12a is displayed.

In this case, when an abnormality occurs, the red backlight 14a lights up so that the numeral 12a of the liquid crystal display 10 changes from white to red.

In addition, in the first, second, and third embodiments, the case where the liquid crystal display 12 in which the display form of the background is changed between the reflection type and the transmission type has been described. It is also possible to use the indicator 12.

In this case, when an abnormality occurs, the background 12b of the liquid crystal display 10 changes from white to red by turning on the red backlight 14a.

In addition, in the first, second, and third embodiments, the case where the display of the electrode and the trip display unit 2 is used and the liquid crystal display 12 is used has been described as an example. Instead of the liquid crystal display 12, the fluorescent display tube, the EL In some cases, an indicator and an LED indicator are used.

In the above-described embodiment, the case where an abnormal content of the vehicle is displayed on the odd or trip display unit 2 has been described as an example. Other content is also possible.

In the above-described embodiment, the case where the vehicle gauge is suitable for a passenger car has been described as an example, but it is also possible to apply it to a vehicle other than a passenger car, a two-wheeled vehicle, an agricultural construction machine, or the like.

Since the present invention can display a plurality of information in one display unit (indicator) as described above, it is possible to reduce the number of light emitting elements required for the display of the indicator, thereby reducing the cost of the vehicle instrument and saving the space of the indicator unit in the design unit It can be effective.
