Description

  The present invention relates to a vehicle display device that displays a shift position.

  Conventionally, various vehicle display devices that display a shift position of a transmission have been proposed. For example, Patent Document 1 discloses the display device. Such a vehicle display device detects a shift position selected by a vehicle driver by operating a shift lever using a shift position sensor, and displays the shift position on a display in a combination meter.

JP 2011-112095 A

However, since a certain area in the combination meter is occupied by the shift position display, there is a problem that an area for displaying other vehicle information becomes relatively small.
The present invention has been made in view of this problem, and provides a vehicle display device capable of appropriately turning on / off all or part of a shift position display.

  The present invention includes a display 30 that displays an image, a control unit 50 that displays the image on the display 30, and a detection unit 63 that detects that the shift operation unit has been touched and outputs contact data. The control means 50 displays a shift position on the display 30 based on the contact data.

  Further, according to the present invention, the control means 50 displays only the shift position where the shift operation is possible on the display 30.

  Further, according to the present invention, the control means 50 does not display a shift position on which the shift operation is impossible on the display 30.

  Further, according to the present invention, the control means 50 stops displaying the shift position after a predetermined time after inputting the non-contact signal from the detection means 63.

  Since the shift position display can be appropriately turned on / off, a dedicated display for displaying the shift position is not required.

The front view which shows 1st embodiment of this invention. The block diagram which shows embodiment same as the above. Display example explanatory drawing which shows embodiment same as the above. Display example explanatory drawing which shows 2nd embodiment of this invention. Display example explanatory drawing which shows embodiment same as the above.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. 1 to 3 show a first embodiment. The vehicle display device includes pointer-type meters 10 and 20 and a liquid crystal display 30.

  The pointer-type instrument 10 is a speedometer that displays the vehicle speed, and the pointer-type instrument 20 is a tachometer that displays the engine speed. The pointer-type meters 10 and 20 have dial plates 11 and 21 and pointers 12 and 22 and stepping motors 13 and 23, respectively. The dial plates 11 and 21 have indicator portions 11a and 21a indicated by the hands 12 and 22, respectively. The pointers 12 and 22 are rotated by the stepping motors 13 and 23 to indicate the indicator portions 11a and 21a of the dial plates 11 and 21. The turning member 40 is formed with circular openings 41 and 42 corresponding to the pointer type instrument 10 and the pointer type instrument 20 and a rectangular opening 43 corresponding to the liquid crystal display 30.

  FIG. 2 is a block diagram showing an electrical configuration of the vehicle display device. The microcomputer 50 has a CPU 51, ROM 52, and RAM 53. The speed sensor 61 detects the vehicle speed and outputs speed data to the microcomputer 50. The rotation sensor 62 detects the rotation speed of the engine and outputs the rotation speed data to the microcomputer 50.

  The touch sensor 63 is composed of, for example, a capacitance switch, and is disposed on a shift lever of the vehicle. The touch sensor 63 detects whether the vehicle driver is touching the shift lever and outputs contact data to the microcomputer 50. The touch sensor 63 outputs a contact signal to the microcomputer 50 when the vehicle driver is touching the shift lever, and outputs a non-contact signal to the microcomputer 50 when the vehicle driver is not touching the shift lever. The shift position sensor 64 detects the shift position of the transmission and outputs shift position data to the microcomputer 50.

  The microcomputer 50 drives the stepping motors 13 and 23 and the liquid crystal display 30 based on a predetermined program stored in the ROM 52. The liquid crystal display 30 includes a liquid crystal display panel (display panel) 31 formed of a TFT (Thin Film Transistor) type liquid crystal display element, and a light emitting element 32 that transmits and illuminates the liquid crystal display panel 31.

  Next, an example of the shift position display will be described based on FIG. When the microcomputer 50 continues to input a non-contact signal from the touch sensor 63, the microcomputer 50 displays the total travel distance (ODD meter) and the section travel distance (TRIP meter) on the screen 30a of the liquid crystal display 30 (FIG. 3). (See (a)). The microcomputer 50 displays the shift position on the screen 30 a of the liquid crystal display 30 when a contact signal is input from the touch sensor 63. For example, if the shift position is in the “P (parking)” state, an image representing the shift positions “R (reverse)”, “N (neutral)”, “D (drive)” and the operation direction of the shift lever are represented. An image such as an arrow mark is displayed (see FIG. 3B). At this time, an image representing the shift position “L (low)” is not displayed.

  When the shift position “D” is selected by the shift lever, the microcomputer 50 displays images representing the shift positions “R”, “N”, and “L” on the screen 30a of the liquid crystal display 30 (FIG. 3C )reference). At this time, an image representing the shift position “D” is not displayed. When a predetermined time (for example, 1 second) elapses after the microcomputer 50 inputs a non-contact signal, the screen 30a of the liquid crystal display 30 returns to the display of the accumulated travel distance and the section travel distance.

  Next, a second embodiment will be described based on FIG. 4 and FIG. The electrical configuration of the second embodiment is the same as that of the first embodiment.

  When the microcomputer 50 continues to input a non-contact signal from the touch sensor 63, the image representing the current shift position “P”, the accumulated travel distance (ODD meter), and the section are displayed on the screen 30 a of the liquid crystal display 30. The travel distance (TRIP meter) is displayed (see FIG. 4A).

  When the touch signal is input from the touch sensor 63, the microcomputer 50 displays the current shift position, the operable shift position, and the section travel distance (TRIP meter) on the screen 30a of the liquid crystal display 30. For example, if the current shift position is “P (parking)”, the shift positions “P (parking)”, “R (reverse)”, “N (neutral)”, “D (drive)” are represented. An image, an image such as an arrow mark indicating the operation direction of the shift lever, and a section travel distance (TRIP meter) are displayed (see FIG. 4B). At this time, an image representing the shift position “L (low)” is not displayed. The section travel distance (TRIP meter) is displayed smaller than usual.

  When the shift lever is operated to select the shift position “D”, the arrow mark corresponding to the shift position “D” is highlighted and displayed in a color different from the other arrow marks (see FIG. 4C). ). At this time, the shift position “P” is not displayed.

  When the shift position “D” is selected, the microcomputer 50 displays images representing the shift positions “D”, “R”, “N”, and “L” on the screen 30a of the liquid crystal display 30 (FIG. 4 ( d)). When a predetermined time (for example, 1 second) elapses after the microcomputer 50 inputs a non-contact signal, the screen 30a of the liquid crystal display 30 displays an image representing the current shift position “D”, an integrated travel distance (ODD meter), and The display returns to the normal display displaying the section travel distance (TRIP meter).

  According to the first and second embodiments, since the liquid crystal display 30 can be used for the display of the accumulated travel distance and the section travel distance and the shift position display, a dedicated display for the shift position display is not required. . In the shift position display, only the shift positions that can be shifted are displayed, and the shift positions that cannot be shifted are not displayed, so that the shift positions that can be shifted can be easily grasped.

  The present invention is not limited to this embodiment, and various modifications are possible. For example, the detection means may be a micro switch. The display may be an organic EL panel.
