That is, the ultraviolet irradiation unit 25 is configured not to be directly recognized by the user. In the best mode, the case where ultraviolet rays are irradiated from below the dial 11 by the ultraviolet irradiation unit 25 will be described. However, depending on the configuration of the combination meter 1, the ultraviolet irradiation unit 25 may be above or below the dial 11. Various embodiments can be made such as irradiating ultraviolet rays from the direction.

  The ultraviolet irradiation unit 25 is provided on the wiring board 26 and is connected to a control unit to be described later via the wiring board 14, and is controlled to be turned on and off by the control unit. And the ultraviolet irradiation part 25 irradiates the ultraviolet-ray U toward the whole dial 11 when lighting is requested | required by the control part.

  The combination meter 1 includes a control unit 31, an interface (I / F) 32, an EEPROM 33, and a plurality of drivers 34. The control unit 31 is connected to the vehicle display device 10 for the speedometer A, the tachometer B, the fuel meter C, and the thermometer D, the LCD 40 for the od trip meter, and the like. It is the structure which can control.

  The control unit 31 basically includes a microcomputer including a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (A Read / Write Memory as needed). The CPU executes various processes including control according to the present embodiment in accordance with a control program stored in the ROM. The RAM appropriately stores data, programs, and the like necessary for the CPU to execute various processes. The control unit 31 is driven by a power supply circuit 30a supplied from a vehicle battery (+ B) or the like.

  The I / F 32 is connected to the in-vehicle LAN, and detects a vehicle state such as a vehicle speed sensor and a rotation sensor connected to the in-vehicle LAN to generate information indicating the vehicle state (for example, vehicle speed information). Various types of information can be transmitted to and received from a detection device (not shown). And the information received from those vehicle state detection apparatuses is output to the control part 31. FIG. In addition, it can also be set as embodiment which connects a vehicle state detection apparatus directly.

  The EEPROM 33 stores a plurality of drive programs corresponding to all the vehicle display devices 10 that can be connected to the control unit 31. Each drive program is associated with instrument identification information to be described later, and is configured to be able to specify the corresponding drive program from the instrument identification information.

  The plurality of drivers 34 include a warning driver 34a, a transmitted illumination driver 34b, and an ultraviolet irradiation driver 34c. A light source (not shown) of the shift indicator 3 is connected to the warning driver 34 a and controls lighting and extinguishing in response to a request from the control unit 31. The light source 15 of each vehicle display device 10 is connected to the transmitted illumination driver 34b, and lighting and extinguishing are controlled according to a request from the control unit 31. The ultraviolet irradiation driver 25 c is connected to the ultraviolet irradiation unit 25 of each vehicle display device 10 and controls lighting and extinguishing in response to a request from the control unit 31.

An illuminance sensor 50 is connected to the control unit 31 and an illuminance signal corresponding to the ambient illuminance is input. In addition, the control unit 31 is connected to a variable resistor 61 for transmission illumination and a variable resistor 62 for ultraviolet illumination, so that the duty ratio of the voltage applied from the power supply V _CC can be arbitrarily set. Yes.

  Next, an example of the time difference lighting process according to the present invention performed by the control unit 31 described above will be described below with reference to the flowchart of FIG.

  In step S11, initialization for setting initial values in each region, variable, and the like is executed. In step S12, it is determined whether or not illumination + is ON. If it is determined that it is not ON (N in S12), this determination process is repeated to wait for the illumination + to change to ON. On the other hand, if it is determined that the illumination + is ON (Y in S12), the process proceeds to step S13.

  In step S13, when the driver 34b is requested to turn on the light source 15 for transmitted illumination, the driver 34b turns on the light source 15 and also times out when a predetermined time corresponding to the time difference lighting elapses. The timer is started, and then the process proceeds to step S14.

  In step S14, it is determined whether or not a predetermined time has elapsed based on whether or not a timeout has occurred. When it is determined that the predetermined time has not elapsed (N in S14), this determination process is repeated to wait for the predetermined time to elapse. On the other hand, if it is determined that the predetermined time has elapsed (Y in S14), the process proceeds to step S15.

  In step S15, when the driver 34c is required to turn on the ultraviolet irradiation unit 25, the ultraviolet irradiation unit 25 is turned on by the driver 34c, and the process ends.

  Next, an example of the illumination brightness setting process according to the present invention executed by the control unit 31 described above will be described below with reference to the flowchart of FIG.

  In step S21, initialization for setting initial values in each region, variable, and the like is executed. In step S22, it is determined whether or not illumination + is ON. If it is determined that the illumination is not ON (N in S22), the determination process is repeated to wait for the illumination + to change to ON. On the other hand, when it is determined that the illumination + is ON (Y in S22), the process proceeds to step S23.

  In step S23, an illuminance signal is taken from the illuminance sensor 50, ambient illuminance is detected based on the illuminance signal, and illuminance information indicating the illuminance is stored in the EEPROM 33. In step S24, the illuminance stored in advance in the EEPROM 33. The drive duty ratio determined based on the conversion table and the illuminance information is set in the variable resistors 61 and 62, and then the process proceeds to step S25.

  In step S25, the driver 34b is required to turn on the light source 15 for transmitted illumination, so that the driver 34b turns on the light source 15. In step S26, the driver 34c is required to turn on the ultraviolet irradiation unit 25. Then, the ultraviolet irradiation unit 25 is turned on by the driver 34c, and the process ends.

  Next, an example of the operation (action) of the vehicle display device 10 according to the present invention described above will be described below with reference to the drawings such as FIGS.

  When the light source 15 is first turned on by the time difference lighting control by the control unit 31, the light L is reflected directly or on the reflecting surface 16 toward the indicator display layer 11e of the dial plate 11 and is transmitted through the indicator display layer 11e. To the user. Therefore, the user visually recognizes the indicator display layer 11e with the light and recognizes that the indicator 11a is emitting light. Further, when the light L corresponding to the lighting of the light source 15 for illuminating the pointer is incident on the pointer main body 11c of the pointer 12, the inside thereof is guided toward the distal end of the indicating portion 11a, and the ultraviolet light emitting portion is emitted from the upper surface of the indicating portion 11a. 20 passes through to the user. Therefore, the user visually recognizes the hot print layer 12f applied to the bottom surface of the instruction unit 11a with the light, and recognizes that the instruction unit 11a emits light.

  Thereafter, when the ultraviolet irradiation unit 25 is turned on after the predetermined time has elapsed, the ultraviolet light U is irradiated to the ultraviolet light emitting units 20 of the dial 11 and the pointer 12 so that each ultraviolet light emitting unit 20 emits the ultraviolet light U. Receives light. That is, each ultraviolet light emitting unit 20 develops a color from blue to purple. Since the indicator portion 11a emits and transmits light as usual, the indicator portion 11a is visually recognized by the user so that the color is more vivid than the surrounding ultraviolet illumination.

  As described above, since the time difference lighting control is performed by combining the ultraviolet display after the transmission display alone, a more innovative display can be performed. In addition, about a display order, it can also be set as the display form which combines a transmitted illumination, after irradiating with ultraviolet rays independently. Further, when the illuminance around the vehicle changes, the duty ratio is changed and the amount of light emission is adjusted. Therefore, a display form in which transmitted illumination and ultraviolet illumination are combined can be realized regardless of the surrounding illuminance.

  In the case of the first index 11a1, since the ultraviolet display and the transmissive display are combined, the color can be more vividly generated and the user can recognize the blue color vividly. In the case of the second indicator portion 11a2, since only the transmissive display is provided, the primary color of the indicator display layer 11e can be recognized by the user, so that color mixing due to ultraviolet rays does not occur and the normal indicator 11a It does not degrade the quality.

  According to the vehicular display device 10 described above, the dial 11 combined with the transmission display and the ultraviolet light emission display is displayed, so that the user can clearly recognize the indicator 11a in the ultraviolet light emission display. Therefore, a novel display form can be realized by obtaining a coloring effect. Further, since it is only necessary to provide the ultraviolet light emitting unit 20 and the ultraviolet irradiation unit 25, it is possible to avoid a complicated structure. Therefore, a novel display form can be realized without complicating the apparatus configuration.

  In addition, since any arbitrary first index 11a1 can be displayed by combining ultraviolet light emission display and transmissive display, the color can be further different from the surrounding color. Further, since the first index 11a1 combining the ultraviolet light emission display and the transmissive display and the second index 11a2 including only the transmissive display can be combined, a more novel display form can be realized.

  Further, since the ultraviolet light emitting portion 20 formed on the surface of the pointer 12 is displayed by ultraviolet light emission, the pointer 12 can be emphasized, so that the design of the pointer 12 is improved and a more novel display form is provided. Can be realized.

  In the combination meter 1 described above, the vehicle display device 10 of the present invention is applied only to the speedometer A and the tachometer B, and normal display instruments are used for the other fuel gauges C and thermometers D. Therefore, a more novel display form can be realized. Of course, even if the vehicular display device 10 of the present invention is applied to all of the speedometer A, the tachometer B, the fuel gauge C, and the thermometer D, a novel display form can be obtained.

  The vehicle display device 10 of the present invention is in a light emitting display state in which the display content is visible when the ignition switch is on, for example, and in a non-light emitting display state so that the display content is invisible when the ignition switch is off. It can also be applied to a combination meter having a smoke panel with a low transmittance of the so-called black face method.
