Therefore, the above problem can be achieved.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

In Figure 1, the automotive air conditioning panel device is
The air conditioner has a panel 1 fitted into an instrument panel, console box, etc., on which the operation and operating status of the air conditioner can be displayed.

A first individual sign 2 is formed at the top of the panel 1 to indicate whether the air introduced into the air conditioner is inside the car (RECIRC) or outside the car (FRESH). The sign part 2 is provided with an inside air circulation indication sign 3 and an outside air introduction indication sign 4, which are equipped with a switch mechanism. By selectively pressing one of the display signs, inside air or outside air is introduced, and the corresponding one of the display signs (3 or 4) lights up.

A temperature setting operation section 5 for setting a target temperature in the vehicle interior is formed near the upper center of the display panel 1, and a second individual indicator section 6 indicating the mode of blowing mode is formed on the left side thereof. The temperature setting operation unit 5 is provided with an operation lever 7 that can be moved up and down along a scale, and when the operation lever 7 is located at the center, the target temperature is set to 25°C.
The target temperature can be set higher as the target temperature is moved upward, and lower as the target temperature is moved downward. On the other hand, the second individual sign section 6 is provided with a defrost indication sign 8, a vent indication sign 9, a bi-level indication sign 10, and a heat indication sign 11 from above.
It has switch parts 8a to 11a on the left end of which are drawn arrows indicating the blowing direction. Each display sign 8-11
When any one of the switch parts 8a to 11a is pressed, a blowout mode corresponding to the display mark of the pressed switch part 8a to 11a is set, and the display mark lights up.

A third individual indicator 12 is formed near the lower center of the display panel 1 to indicate the control status of the blower as AUTO, LOW, MED, or HIGH.
This third individual sign section 12 includes a blower automatic control sign 13 equipped with a switch mechanism, and a low speed control sign 1.
4. A medium speed control sign 15 and a high speed control sign 16 are provided. By selectively operating each control indicator 13 to 16, the rotation level of the blower can be set to LOW,
MED, HIGH or automatically set so that the corresponding control indicator lights up.

A fourth individual indicator 17 is formed at the bottom of the panel 1 to indicate the driving state of the compressor. This indicator part 17 is provided with an indicator 18 that displays the level of operation rate of the compressor.
The indicator is colored up to the level position corresponding to the operating rate.

Furthermore, on the right end of panel 1, there is a release sign (OFF) 19 for canceling the control of the air conditioner, which automatically controls the blowing mode by suppressing the level of the blower and compressor to achieve economical air conditioning in the vehicle interior. A first automatic control sign (ECON) 20 indicating that all operations of the air conditioner are automatically controlled and a second automatic control sign (AUTO) 21 indicating that all operations of the air conditioner are automatically controlled are provided. Both the release indicator 19 and the first and second automatic control indicator sections 20 and 21 have a switch mechanism,
By selectively operating each sign, corresponding control is performed, and the first and second automatic control sign sections 2
At 0 and 21, the selected side lights up. In addition, when the first or second automatic control sign section 20, 21 is operated, a diagram 22 appears on the panel 1, indicating the selected automatic control sign section and the object to be controlled by this automatic control sign section. are associated with individual indicator portions indicating each of them.

In this embodiment, the diagram 22 shows the automatic control marking sections 20, 21 and the individual marking sections 2, 6, 12, 17.
It consists of ruled lines that appear between
The lighting of various signs and the like are controlled by a microcomputer 23.

The microcomputer 23 is a central processing unit.
It has a CPU, a random access memory RAM, a read-only memory ROM, an input/output port I/O, etc., and is known in itself. and,
When the signals from each of the signs are input, the microcomputer 23 performs arithmetic processing on the signals according to a predetermined program to determine a display signal, and sends this display signal to the panel 1 via the display control circuit 24. It is now output to , especially line diagram 2.
An example of the display control routine of No. 2 is shown as a flowchart in FIG.

That is, the microcomputer 23 starts executing the program from step 50 when the ignition switch is turned on, resets the CPU, etc. in the next step 52, and then starts the first automatic control in step 54. It is determined whether the marker section 20 has been selected. If it is determined in this step 54 that the first automatic control indicator section 20 has been selected (YES), the process proceeds to step 56, where the first automatic control indicator section 20 and the second automatic control indicator section 20 are selected as shown in FIG. The ECON display mode is set in which the fourth individual marker portions 6, 12, and 17 are connected by the line diagram 22.

On the other hand, if it is determined in step 54 that the first automatic control indicator is not selected (NO), the process advances to step 58, where the second automatic control indicator is selected.
It is determined whether or not the automatic control indicator section 21 has been selected. In this step 58, if it is determined that the second automatic control indicator has been selected (YES),
Proceeding to step 60, as shown in FIG. 4, the second automatic control sign section 21 lights up and the second automatic control sign section 21 and the first to fourth individual sign sections 2
AUTO where 6, 12, and 17 are connected as shown in diagram 22
Enters display mode. Also, in step 58,
If it is determined that the second automatic control indicator 21 is not selected (NO), the process proceeds to step 62, and a non-display mode is entered in which the line diagram 22 is not displayed.

After one of the ECON display mode, AUTO display mode, and non-display mode is selected, the process returns to step 54.

Therefore, depending on the content of automatic control, line diagram 22
is switched and displayed, and it is possible to recognize the control target of each automatic control sign section using this line diagram.
It can be seen that the control corresponding to the individual marker portions that are not connected by the diagram (in this embodiment, the first individual marker portion in the ECON display mode) must be manually performed.

Note that in this embodiment, ruled lines are used as line drawings, but arrows or other figures may also be used.

(Effects of the invention) As described above, according to this invention, the correspondence between automatic control signs and individual sign parts is clarified by the diagram, so it is easy to visually identify the control target of automatic control signs. It is possible to obtain an easy-to-use panel device for automobile air conditioning that allows the user to recognize and operate the air conditioner accurately based only on the display on the panel.
