  Such a vehicle cluster includes an analog type, a digital type, and an analog and digital type depending on an operation method. The analog system is a system in which information on a running state such as a speed and a rotational speed is displayed through a pointer operated by a drive motor. The digital type is a method in which information on the running state such as speed and rotational speed is displayed as numbers that are accurate digital data. The analog and digital method is a method in which both an analog method and a digital method are displayed. On the other hand, in recent years, digital or analog and digital that provides the driver with more brilliant and rich content through a high-resolution display means that is digitized, that is, LCD panel, without depending on the pointer, in accordance with the digital age. Type vehicle clusters are installed in newly released vehicles.

  For example, as shown in FIGS. 1 to 4, the analog and digital vehicle cluster 30 according to the related art is fixedly installed on the dashboard 20 fixedly installed behind the steering wheel 10 of the vehicle 1 and opened. A cluster housing 31 having a transparent window 32 fixedly coupled to the front, a cluster PCB 33 installed inside the cluster housing 31 and electrically connected to an ECU 40 for receiving information from various sensors installed in the vehicle, and a cluster PCB 33 A cluster dial 34 that is fixedly installed inside the cluster housing 31 while being positioned in front of the vehicle, is printed with letters and numbers for displaying the running state of the vehicle 1, and includes a speedometer 35 that displays the speed of the vehicle; , Coupled to the output shaft of the pointer drive motor 37 to indicate the current running state of the vehicle 1 A pointer 36 rotatably installed in front of the cluster dial 34, a dial light source 38 that is electrically connected to the cluster PCB 33 and supplies illumination to the cluster dial 34, and a cluster PCB 33, and is electrically connected to the cluster PCB 33. It includes an LCD panel 39 that is exposed in front of the dial 34 and displays the current running state of the vehicle 1 as digital data. At this time, it is a digital vehicle cluster that displays the vehicle speed information on the LCD panel 39 as digitalized digital data without the speedometer 35 and the pointer 36.

  Digital and analog-and-digital vehicle clusters are frequently in contact with digital equipment and can be used by young drivers who use them while easily confirming information on various driving conditions of the vehicle through the LCD panel. Although it may be possible, older drivers who are not used to digital devices and have a weak body and cognitive ability can not feel the necessity of LCD panels that display brilliant digital data, but rather refuse There is a problem that can give a feeling. In other words, since elderly drivers who are accustomed to analog vehicle clusters mainly drive while checking mainly speedometers, an LCD panel on which information on various driving conditions of the vehicle is digitized and displayed Rather than feeling the need for, there is a possibility of having a sense of refusal. Further, due to the above-mentioned problems of the digital vehicle cluster and the classic boom, the number of drivers who prefer the analog vehicle cluster is increasing regardless of age.

  However, as described above, the clusters installed in the vehicles that are currently on the market are less analog and tend to be almost digital or analog and digital.

  Hereinafter, a preferred embodiment of a vehicle cluster system according to the present invention will be described in detail with reference to the accompanying drawings.

(First embodiment)
First, the vehicle cluster system according to the first embodiment of the present invention includes a cluster housing 100, a cluster PCB 200, a cluster dial 300, an LCD panel 400, a speedometer pointer 500, a dial as shown in FIGS. A light source 600 and a UV speed meter display unit 700 are included.

  As shown in FIGS. 5, 6, and 8, the cluster housing 100 is fixedly installed on the dashboard 20 fixedly installed behind the steering wheel 10 of the vehicle 1, and the cluster window 110 is fixedly coupled to the front of the opening. . The cluster housing 100 includes fastening means for fastening fastening members such as a fixing clip, a fixing bracket, and a fixing pin so that the cluster housing 100 can be fixedly installed on the dashboard 20, although not shown in the drawing. The dashboard 20 is provided with a mounting portion that is recessed or penetrated in the front-rear direction so that the cluster housing 100 is fixedly installed while the cluster housing 100 is accommodated.

  In the cluster window 110, a cluster dial 300, an LCD panel 400, a speedometer pointer 500, and a UV speedometer display 700, which will be described later, installed in the cluster housing 100 are visible to the driver (or the user). Thus, it consists of a light transmissive material like a transparent synthetic resin. On the front surface (back surface) of the cluster window 110, a UV blocking film 111 is attached or UV coated in order to block UV light emitted from a UV light source 720 described later. That is, UV light is not transmitted to the driver by blocking the UV light from being transmitted outside the cluster window 110 with the cluster window 110 as a boundary.

  As shown in FIG. 8, the cluster PCB 200 is installed inside the cluster housing 100, and is electrically connected to an ECU 40 that receives information from various sensors installed in the vehicle. In order to supply power, the battery installed in the vehicle 1 is also electrically connected. On the other hand, the ECU 40 is an electronic control unit (Electronic Control Unit), and can be said to be an automobile computer. The ECU 40 is provided with a RAM and a ROM. The RAM of the ECU 40 has a function of temporarily storing various signals generated during operation of the automobile, and the ROM has a function of storing a control program and control data necessary for the automobile to move. Such an ECU 40 includes various sensors installed in the vehicle at the same time as the vehicle power is turned on, for example, a sensor for checking an engine speed related to the engine, an amount of engine oil, an air conditioning related temperature sensor, a safety air bag, Information is received from various sensors such as a seat belt sensor, a speed related to vehicle movement, an ABS, and a left / right rotation sensor. At this time, communication of all signals received or transmitted to the ECU 40 is performed by CAN communication which is an automobile communication standard. Since the functions and operations of the ECU 40 and various sensors installed in the vehicle 1 are widely known in the conventional automobile technology, detailed description thereof is omitted.

  As shown in FIGS. 6 to 9, the cluster dial 300 is fixedly installed inside the cluster housing 100 while being positioned in front of the cluster PCB 200, and letters and numbers for displaying the running state of the vehicle 1 are formed. The transparent plate 310 is integrally formed at a certain portion. Here, the reason for forming the transparent plate 310 is that digital data 410 and a speedometer 420 displayed on the LCD panel 400, which will be described later, are transparently displayed so that they can be viewed from outside the front of the cluster dial 300, and will be described later. This is because the UV speedometer 710 is printed on a part of the front surface of the cluster dial 300 including the transparent plate 310. The characters and numbers for displaying the running state of the vehicle 1 on the cluster dial 300 are signals received from the ECU 40, except for the speed, engine speed (RPM), ABS, fuel gauge, seat belt warning light. In order to display a cooling water thermometer, an upward light indicator light, an engine oil warning light, a battery warning light, and other warning lights and indicator lights. At this time, the speedometer that displays the speed of the vehicle 1 is displayed on the LCD panel 400, which will be described later, and therefore may not be displayed on the cluster dial 300.

  As shown in FIGS. 6, 8, 10, 11 and 12, the LCD panel 400 is fixedly installed behind the transparent plate 310 of the cluster dial 300 and is electrically connected to the cluster PCB 200. The LCD panel 400 displays the current running state of the vehicle 1 as digitized digital data 410, and displays numbers and scales constituting the speedometer 420 for displaying the speed of the vehicle 1.

  Here, the digital data 410 receives a signal from the ECU 40 and receives the engine speed (RPM), ABS, fuel gauge, seat belt warning light, cooling water thermometer, upward light indicator light, engine oil warning light, battery warning light. Other warning lamps and indicator lamps are displayed with characters and numbers formed on the cluster dial 300, that is, for displaying digitally, not analog, from the ECU 40 received by the cluster PCB 200. This is for displaying the signal as a digitized number. For example, FIG. 11 and FIG. 12 show an example of displaying the vehicle running speed, the gear position of the automatic transmission, the odometer, and a warning that the vehicle door is open as the digital data 410. When the digital data 410 is displayed in this way, the current traveling state of the vehicle 1 can be displayed more accurately than in the analog type.

  The speedometer 420 is digitized on the LCD panel 400, unlike the conventional speedometer formed in an analog-type cluster, that is, the numbers and scales are simply formed on the cluster dial. Is displayed. As shown in FIGS. 10 to 12, the speedometer 420 is selectively applied to the LCD panel 400 according to an N mode, an A mode, and an AD mode determined by a mode operation unit 800 and a mode control unit 900 described later. Is displayed. That is, the screen displayed on the LCD panel 400 is not limited to a single screen, and the digital data 410 and / or the speedometer 420 can be selectively displayed. Further, the LCD panel 400 may be a compact TFT-LCD (Thin Film Liquid Crystal Display) having a thickness and weight significantly reduced as compared with a general LCD.

  The speedometer pointer 500 is coupled to the output shaft of the pointer drive motor 510 so as to indicate the current speed of the vehicle 1 as shown in FIGS. It is installed to be able to rotate forward. The pointer drive motor 510 is electrically connected to the cluster PCB 200, and when the cluster PCB 200 receives a current vehicle speed signal from the ECU 40, the pointer drive motor 510 is driven to rotate to an angle corresponding to the received speed signal. . Thereby, the speedometer pointer 500 can indicate the corresponding scale of the speedometer 420 or the UV speedometer 710. The speedometer pointer 500 is made of a light-transmitting material having a UV ink 520 that is colored only when UV light is illuminated through a UV light source 720 to be described later, and indicates the speedometer 420 of the LCD panel 400. Thus, the sheet paper 530 is pasted or painted on a certain portion of the lower layer of the printing surface of the UV ink 520. The UV ink 520 is a special ink that develops color only with UV light of a specific wavelength, corresponds to a phosphor (or phosphorescent substance), and is located behind the UV ink 520 (lower layer) only when UV light is not irradiated. It is usually light transmissive so that a surface and an object can be seen. By utilizing such characteristics of the UV ink 520, only the portion of the sheet paper 530 of the speedometer pointer 500 is displayed depending on whether the UV light source 720 is irradiated, or the entire surface is colored by UV light, and the speedometer pointer is displayed. By 500, the scale of the speedometer 420 of the LCD panel 400 or the scale of the UV speedometer 710 of the UV speedometer display unit 700 described later can be instructed.

  In addition to the speedometer pointer 500, as shown in FIG. 6 and the like, in front of the cluster dial 300, a tachometer, a fuel gauge and a water temperature meter formed on the cluster dial 300 are indicated. Pointers can be rotatably coupled.

  As shown in FIG. 8, the dial light source 600 is electrically connected to the cluster PCB 200 and irradiates the cluster dial 300 with illumination light. For this reason, a dial light source PCB 610 and a light diffusing plate 620 electrically connected to the cluster PCB 200 are provided. The dial light source 600 is environmentally friendly compared to a general light source, consumes less power, and can use a long-life LED (Light Emitting Diode). The dial light source 600 emits illumination light to characters and numbers formed on the cluster dial 300 in order to display the running state of the vehicle 1 so that the driver can easily recognize the running state of the vehicle 1. can do.

  As shown in FIGS. 6 to 9 and 15, the UV speedometer display unit 700 is larger than the speedometer 420 of the LCD panel 400 on the front face of the cluster dial 300 so that the color is generated only when UV light is irradiated. A UV speedometer 710 printed with ink and a UV light source 720 that irradiates UV light toward the UV speedometer 710 are provided. That is, the UV speedometer 710 is obtained by printing UV ink on a part of the front surface of the cluster dial 300 including the transparent plate 310, and the number and scale for displaying the speedometer are printed by the UV ink. The The UV light source 720 is electrically connected to the cluster PCB 200, arranged at equal intervals inside the cluster housing 100 between the cluster window 110 and the cluster dial 300, and irradiates UV light toward the UV speedometer 710. To do. This is to prevent the UV light from being directly irradiated toward the driver. Further, a UV blocking film 111 is attached to the inner surface (back surface) of the cluster window 110 in order to block the UV light emitted from the UV light source 720. Instead of the UV blocking film 111, UV coating may be applied. Thereby, it can prevent more reliably that a driver | operator is irradiated with UV light. The UV light emitted from the UV light source 720 is UV light having a specific wavelength so that the UV ink of the UV velocimeter 710 can develop color.

  The reason why the UV speedometer 710 is printed larger than the speedometer 420 of the LCD panel 400 is because the body and cognitive ability is lowered and the driver of the elderly with low vision is considered. This is to improve the visibility of 710 so that an elderly driver can easily recognize the current traveling speed of the vehicle 1.

  As shown in FIGS. 5, 8 and 16, the mode operation unit 800 is fixedly installed inside the vehicle 1 so that the driver can operate, so that the driver can easily operate. It can be installed on the steering wheel 10 close to the driver. Then, an N mode operation button 810 that transmits an N mode signal of a general mode to a mode control unit 900 described later by an operation of the driver, and an A mode that transmits an A mode signal of an analog mode to the mode control unit 900 by an operation of the driver. A mode operation button 820 and an AD mode operation button 830 that transmits an AD mode signal in an analog and digital mode to the mode control unit 900 by a driver's operation are included.

  As shown in FIGS. 5, 8, and 16, the mode control unit 900 is electrically connected to the mode operation unit 800 and controls the operation of the UV speed meter display unit 700 according to a signal from the mode operation unit 800. The mode control unit 900 turns on the LCD panel 400 by the N mode signal of the mode operation unit 800 and turns off the LCD panel 400 by the N mode control unit 910 that turns off the UV light source 720 and the A mode signal of the mode operation unit 800. Meanwhile, both the LCD panel 400 and the UV speedometer display unit 700 are operated by the A mode control unit 920 that turns on the UV light source 720 so that the UV speedometer display unit 700 operates, and the AD mode signal of the mode operation unit 800. And an AD mode control unit 930 for turning on the LCD panel 400 and the UV light source 720. At this time, the LCD panel 400 is controlled by the N mode control unit 910 to display the current running state of the vehicle 1 as digital data while displaying the speedometer 420, and by the AD mode control unit 930. Control is performed so that the current running state of the vehicle 1 is displayed as digitalized data while the speedometer 420 is not displayed. Such display control of the LCD panel 400 will be described in more detail with reference to FIGS.

  17 to 19 are front views illustrating display examples in the N mode, the A mode, and the AD mode of the vehicle cluster system according to the first embodiment.

  First, FIG. 17 illustrates a display example in the N mode. When the driver (or the user) operates the N mode operation button 810 of the mode operation unit 800, the N mode control unit 910 of the mode control unit 900 is illustrated. Controls so that the speedometer 420 is displayed on the LCD panel 400. In this case, the current speed of the vehicle is instructed in the speedometer 420 by the sheet paper 530 of the speedometer pointer 500. In this case, in addition to the speedometer 420, the digital data 410 may be simultaneously displayed on the LCD panel 400. The digital data 410 may include the current vehicle speed displayed in digital form. In other words, the N mode is a general mode, and can also be referred to as a speedometer digital mode in which a part of the speedometer 420 that displays the current traveling speed of the vehicle is digitized and displayed. However, this is a mode system in which only the speedometer portion is limited and a mode name is given. When all of the fuel gauge, tachometer, water temperature gauge, etc. formed on the cluster dial 300 are taken into consideration, the vehicle cluster system The overall mode may correspond to an analog and digital mode.

  Next, FIG. 18 illustrates a display example in the A mode. When the driver operates the A mode operation button 820 of the mode operation unit 800, the A mode control unit 920 of the mode control unit 900 displays the LCD panel. By turning off the 400 and turning on the UV light source 720, the UV speedometer 710 is displayed. Then, the UV ink printed on the entire front surface of the speedometer pointer 500 is colored by the UV light of the UV light source 720, and the number and scale of the UV speedometer 710 can be indicated. At this time, control may be performed so that a part of the dial light source 600 is turned off so that the visibility of the UV speedometer 710 is further enhanced. In other words, the A mode is an analog mode, and it can also be called a speedometer analog mode in which the speedometer portion that displays the current traveling speed of the vehicle is analogized.

  Finally, FIG. 19 shows a display example in the AD mode. When the driver operates the AD mode operation button 830 of the mode operation unit 800, the AD mode control unit 930 of the mode control unit 900 displays the LCD. The panel 400 is turned on and the UV light source 720 is turned on.
