Description

  The present invention relates to a vehicle display device.

  As shown in FIG. 4, a general vehicle display device includes independent analog indicating meters such as a speedometer 11, a tachometer 12, a fuel gauge 13, a water temperature gauge 14, and a gear position. It has the structure of the combination meter provided with display parts, such as the display part 15 and the direction indicator display part 16. FIG. These meters and display units are arranged between the case 21 and the front glass 22. Further, visibility and decorativeness are improved by the facing plate 23, the decorative rings 11c and 12c, and the like.

  The speedometer 11 has a circular dial plate 11a and a pointer 11b. The dial 11a is provided with a scale 11a1 composed of scale lines and numbers near the outer periphery thereof, and a speed unit 11a2 is provided near the center.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram illustrating a configuration of a vehicle display device according to an embodiment of the present invention, FIG. 2 is a flowchart illustrating display switching processing, and FIG. 3 is a diagram illustrating a specific example of display switching. It is.

  In FIG. 1, a vehicle display device includes a main CPU 1 as a determination unit and a control unit, an I / O (input / output) circuit 2, an EEPROM 3 as a storage unit, a graphic control CPU 4 as a control unit, and a graphic control. An IC 5, a graphic data memory 6, a full color / dot matrix type LCD unit 7 as an image display, and a display changeover switch 8 as a display changeover means.

  The main CPU 1 receives various detection signals, for example, a traveling speed signal (SPEED), detected from the node 10 of the vehicle-side LAN via the I / O circuit 2 by the CAN communication unit. The CAN communication unit uses CAN (Controller Area Network) as a communication protocol.

  The main CPU 1 computes various detection signals such as the received traveling speed signal (SPEED), outputs a display value signal, and supplies it to the display graphic control CPU 4. The main CPU 1 reads a basic display signal representing a display design stored in advance in the EEPROM 3 and displayed on the screen of the LCD unit 7 and supplies it to the display graphic control CPU 4. The graphic control CPU 4 takes in the basic display signal and the display value signal supplied from the main CPU 1, performs drawing processing, and outputs an image display signal. The graphic control CPU 4 stores the image display signal in the graphic data memory 6 and outputs it to the graphic control IC 5.

  The graphic control IC 5 drives the LCD unit 7 by the supplied image display signal. The graphic control IC 5 is driven so that the supplied image display signal is displayed on the display screen of the LCD unit 7 as a composite screen having a plurality of layer structures. For example, the graphic control IC 5 can display and superimpose image display signals in a window format of six screens.

  The LCD unit 7 functions as a full graphic meter. Under the control of the main CPU 1 and the graphic control CPU 4, the display screen 7a is displayed on the display screen 7a based on various detection signals supplied from the vehicle side. Various meters such as a tachometer 12 that indicates the number of revolutions, a fuel meter 13 that indicates the remaining amount of fuel, and a water temperature gauge 14 are displayed in an analog instruction system, and a display unit such as a direction indicator display unit 16 is also displayed.

  Further, the LCD unit 7 switches the dial of the speedometer 11 displayed on the screen to the mile display or the kilometer display under the control of the main CPU 1 and the graphic control CPU 4 based on the operation of the display changeover switch 8.

  Next, a speedometer display switching process executed by the above-described vehicle display device will be described with reference to a flowchart shown in FIG.

  First, initialization is performed by turning on the power by turning on the ignition switch of the vehicle (step S1). Next, by reading basic display information from the EEPROM 3 on the screen of the LCD unit 7, as shown in FIG. An initial state is displayed in which display designs representing various meters such as a tachometer 12, a fuel gauge 13, a water temperature gauge 14, and a display unit such as a direction indicator display unit 16 are displayed (step S2). In this initial state display, as shown in FIG. 3A, the circular dial 11a of the speedometer 11 has a scale 11a3 for displaying miles in the vicinity of the outer periphery of the dial 11a. A speed instruction unit (MPH) 11a4 is displayed near the center.

  Next, it is determined whether or not a switching instruction for switching from mile display (target to be switched) to kilometer display (target to be switched) has been made (step S3). Here, when the display changeover switch 8 is turned on, a manual switching instruction signal is input to the CPU 1, and the CPU 1 determines that a switching instruction for switching from mile display to kilometer display has been performed. If the answer to step S3 is no, then the process returns to step S2, and if yes, the process proceeds to step S4.

  When the display changeover switch 8 is turned on, as shown in FIG. 3B, the dial 11a of the speedometer 11 is placed on the EEPROM 3 inside the area where the scale 11a3 for mile display is displayed. The display design representing the scale 11a1 for displaying kilometers and the speed instruction unit (km / h) 11a2 included in the stored basic display information is read out and displayed at a display density lighter than the mile display ( Step S4). At this time, the speed indication unit (MPH) 11a4 for displaying miles in the vicinity of the center of the dial 11a is moved and displayed below the scale (120) indicating the maximum speed of the dial.

  Next, the operation moves to the animation operation mode (step S5). With this animation operation mode, as shown in FIG. 3 (C), the scale 11a1 and the speed instruction unit (km / h) 11a2 displayed in kilometers are gradually displayed darker at a display speed. It expands toward the outer periphery of the dial 11a. With this enlargement, the display density of the mile display gradually decreases from the density in the initial state, and when the kilometer display reaches the outer periphery of the dial 11a, that is, the position where the mile display scale 11a3 is displayed, the animation operation mode is changed. Stop. The pointer 11b is maintained at the normal concentration. The display design displayed on the screen of the LCD unit 7 in the above-described animation operation mode is included in the basic display information stored in the EEPROM 3, and a plurality of animation scenes that change every moment according to the movement of the animation are sequentially read. Is displayed.

  Next, the mile display is stopped (step S6), and the dial 11a is completely switched to the kilometer display as shown in FIG.

  As described above, according to the present invention, the display switching target (km display) is displayed lightly at a position different from the switching target (mile display), and then the density and position are gradually exchanged between the switching target and the switching target. Therefore, there is no stage of non-display, display is always performed even during driving, and display switching is possible without giving a sense of incongruity.

  In addition, two types of speed instruction units are displayed during display switching. However, one type of speed instruction unit is displayed at the end of switching, so that the driver can easily see and does not hesitate to select the speed instruction unit. It is possible to reliably recognize the vehicle traveling state.

  In addition, since the size of the display design can be effectively ensured as compared with the case where the display area is determined as in the prior art, the visibility of the indication position of the pointer is improved. Moreover, the freedom degree of display design arrangement | positioning improves.

  In addition, the state in which the speed instruction unit is switched can be visually recognized in the middle of the switching. For example, if control is performed to gradually change only the display of the speed instruction unit around the rotation angle of the pointer as it is, the pointer is not displayed. Since there is no natural movement and the scale is gradually switched, display switching can be recognized without giving the driver a sense of incongruity or wonder.

  In addition, the display changeover switch 8 can be used to manually change the display, and the display can be prioritized and switched at a timing when the driver desires to change the display.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this, A various deformation | transformation and application are possible.

  For example, in the above-described embodiment, the display design to be switched is a mile display and the display design to be switched is a kilometer display. Instead, the display design to be switched is a kilometer display. The display design to be switched may be displayed as miles.

  Further, in the above-described embodiment, the mile display and the kilometer display on the dial 11a of the speedometer 11 are switched by inputting a manual switching instruction signal by manual operation of the display switch 8 by a driver or the like. Instead of the automatic switching instruction signal input based on the reception of an external signal such as a signal indicating that the vehicle has crossed the border or the state border from the GPS data obtained through the vehicle-side LAN, it is automatically switched. It can also be configured as follows. In this case, the burden on the driver is reduced compared to manual switching of the driver.

  Further, in the above-described embodiment, switching between the mile display / km display is performed, but the gist of the present invention is to gradually change the density after the switching target is displayed lightly at a position different from the switching target, The present invention can also be applied to scale changes in meters other than the speedometer 11, such as the tachometer 12, the fuel gauge 13, and the display position to be switched is not limited to the center as in the embodiment.

  In the above-described embodiment, the LCD unit is used as the image display. However, other display elements such as an organic EL and a plasma display may be used.
