Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shift lever operation position display device for an automatic transmission for an automobile, and more particularly to a shift lever operation position display device that allows the position of the shift lever to be clearly seen. .

A shift lever operating position display device for an automatic transmission is a device that displays the operating position of a shift lever for changing the range of an automatic transmission for the driver to visually recognize.

As a conventional shift lever operation position display device for an automatic transmission, there is one described, for example, in Japanese Patent Publication No. 43-28234. This display device is
A plurality of sign symbols indicating the range of the automatic transmission are arranged in a predetermined order, and display holes are provided in adjacent positions of these sign symbols at a predetermined interval of the same number as the sign symbols. When the shift lever is completely shifted, the indicator is exposed at a selected position in one of the display holes to display the operating position of the shift lever. However, in conventional display devices with such a configuration, when the shift lever is in an incomplete shift state, the indicator is located between adjacent display holes,
This is invisible to the driver, and as a result, there is a problem in that the driver may temporarily lose track of the current position of the shift lever and lose attention to the surrounding situation.

This invention was made by focusing on such conventional problems, and includes a display section in which a plurality of signs indicating the range of an automatic transmission are arranged, and one colorless transparent window is provided along the arrangement. and an indicator that moves in conjunction with the shift lever of the automatic transmission on this window,
a bottom wall located on the back side of the indicator;
The indicator is colored transparent, and the part of the bottom wall corresponding to at least one incomplete shift position of the shift lever is colored with the color of the part of the bottom wall corresponding to the complete shift position of the shift lever and the color of the indicator. This ensures that the indicator is visible through the window at all times, and that the indicator is colored in a different hue when it is in at least one incomplete shift position and when it is in the complete shift position. The color and the color of the bottom wall behind it are superimposed and combined so that the visible color changes, so that the driver can clearly see the current position of the shift lever, and this solves the problem mentioned above. It aims to solve the problem.

The present invention will be explained below based on the drawings.

1 and 2 are diagrams for explaining one embodiment of the present invention.

FIG. 1 is a plan view of the shift lever operating position display device for an automatic transmission according to this embodiment, and FIG. 2 is a sectional view taken along the line -- in FIG. First, the configuration will be explained. Reference numeral 1 denotes a display section, which is made of, for example, a colorless and transparent elongated acrylic plate. On this display section 1, signs 2, that is, P, R, N, D, 2, 1 are arranged vertically in this order. The sign 2 is provided, for example, by printing black on the back surface 1a of the display unit 1 except for the sign 2 and a window portion to be described later, and then printing only the sign 2 in white. The P of sign 2 indicates the P range of the automatic transmission, that is, the range when parking, R indicates the R range, that is, the range when reversing, N indicates the N range, that is, neutral, and D indicates the D Range, that is, the range during normal driving. 2 and 1 indicate 2 ranges and 1 range, respectively, that is, ranges for low speed running. Reference numeral 3 denotes a colorless and transparent vertically elongated window, which is provided in the display section 1 along the arrangement of the signs 2. As described above, the window 3 is provided by printing the back surface 1a of the display section 1 made of a colorless and transparent acrylic plate in black or white except for the portion corresponding to the window 3. Reference numeral 4 denotes an indicator, which is located below the window 3 and is attached to the shift lever 5 so as to be interlocked with a shift lever 5 that operates an automatic transmission (not shown). The indicator 4 is made of plastic material, for example, and is colored red and transparent. 6 is window 3
The bottom wall has an elongated shape that is substantially the same as the display section 1, and is provided on the back side of the indicator 4 to separate the indicator 4 from the lower part of the display device. A surface 6a of the bottom wall 6 facing the window 3 is colored white. If the shift lever 5 is in an incomplete shift position, that is, the shift lever 5 is in the middle of adjacent ranges and has not been completely shifted to any range, and some external force is applied, it will shift to one of the adjacent ranges. Of the portions of the bottom wall 6 that correspond to positions where there is a possibility that the shift may occur on its own regardless of the driver's operating intention, the portion 6b that corresponds to the incomplete shift position between the P range and the R range is located at the bottom. a different hue from the color of the other parts of the wall 6 and the color of the indicator 4;
For example, it is colored blue-green. A light source 7 is provided below the bottom wall 6 and illuminates the surface 6a of the bottom wall 6, the indicator 4, and the window 3.

Next, the action will be explained.

In the shift lever operating position display device configured as described above, the operating position of the shift lever 5 is such that the shift lever 5 is in the complete shift position, that is, the shift lever 5 is in one range position of the automatic transmission. If the range is in a position where it cannot be shifted to another range except by operation by the driver, a red transparent indicator 4 with the surface 6a of the white bottom wall 6 in the background is used.
is visually recognized by pointing to the center of one of the signs 2, ie, P, R, N, D, 2, 1.
In addition, when the shift lever 5 is in the incomplete shift position, except between the P range and the R range, a red transparent indicator 4 with the surface 6a of the white bottom wall 6 as a background indicates the sign 2, that is, the P range. , R, ND, 2, 1 by pointing to the middle of the array. When the shift lever 5 is in the incomplete shift position between the P range and the R range, a red transparent indicator 4 is located on the part 6b of the surface 6a of the bottom wall 6 colored in blue-green, and the indicator 4 is displayed. A person can visually recognize the indicator 4 by seeing the indicator 4, which is a combination of red and blue-green and becomes almost black. Therefore, the driver can clearly see that the shift lever 5 is in the incomplete shift position between the P range and the R range. Therefore, the driver can take care to ensure that the shift lever 5 is placed in the P range or the R range from this incomplete shift position. The reason why the shift lever 5 is prevented from being in an incomplete shift position between the P range and the R range by changing the visible color of the indicator 4 is as follows. In other words, the driver leaves the car thinking that he has put the shift lever 5 into the P range, but the shift lever 5 is actually in the incomplete shift position, and for some reason the shift lever 5 ends up in the R range. There is a risk that the automatic transmission's parking mechanism will not be able to secure the vehicle. Also,
The driver thought he had put the shift lever 5 in the P range and put in the engine key to start the starter motor, but the shift lever 5 was actually in the incomplete shift position and the automatic transmission was in the R range. On the other hand, the inhibitor switch is in the P range, allowing the starter motor to drive, and there is a danger that the car will start running backwards as soon as the engine key is turned in.

FIG. 3 is a diagram showing another embodiment of the invention. It should be noted that the same parts as in the previous embodiment are given the same reference numerals, and the description thereof will be omitted.

In this embodiment, a portion 6 of the surface of the bottom wall 6 corresponds to all incomplete shift positions of the shift lever 5.
b, 6c, 6d, 6e, 6f are the parts 6g, 6h, 6h, 6j, 6 of the surface of the bottom wall 6 corresponding to the color of the indicator 4 and the complete shift position of the shift lever 5.
It is colored in a hue different from that of k and 6l. Therefore, when the shift lever 5 is in the incomplete shift position, the color of the indicator 4 and the parts 6b, 6c of the bottom wall 6,
The colors 6d, 6e, and 6f are combined to create the hue visible to the driver, the color of the indicator 4, and the color of the bottom wall 6 when the shift lever 5 is in the full shift position.
The colors g, 6h, 6i, 6j, 6k, and 6l are combined, and the hue seen by the driver is different. Thereby, the driver can clearly determine whether the shift lever 5 is at the desired position according to his/her operation.

As explained above, according to this invention,
The structure of the shift lever operating position display device of an automatic transmission is such that a colorless and transparent window is provided along the array in a display section in which a plurality of signs indicating the range of the automatic transmission are arranged. An indicator that moves in conjunction with a shift lever of an automatic transmission and a bottom wall located on the back side of the indicator are provided, and the indicator is colored transparent and at least one incomplete shift of the shift lever is provided. The portion of the bottom wall that corresponds to the position is colored with a different hue from the color of the portion of the bottom wall that corresponds to the full shift position of the shift lever and the color of the indicator, so that the indicator
When the indicator is in the two incomplete shift positions and when it is in the complete shift position, the color of the indicator and the color of the bottom wall behind it are superimposed and combined, resulting in a change in the visible color. at least one of the shift levers
This has the effect of making it possible to clearly see two incomplete shift positions. Therefore, erroneous driving operations can be avoided. Additionally, the indicator is visible to the driver through the window no matter what position the shift lever is in.
This prevents the driver from feeling anxious due to even temporarily losing track of the current position of the shift lever.
