Abstract

PURPOSE:To make it possible to respond even to electrical appliances of different operation times by allowing switches to operation-control the electrical appliances only when the power is input to the operation switches continuously more than a specific time, and setting the specific time responding to the operation time of each electrical appliance. CONSTITUTION:While electrical appliances 7 and 8 are made operation-controlled only when operation switches are input continuously more than specific times, the specific times are set responding to the operation times of the electrical appliances 7 and 8. As a result, to the operation switch of a longer operation time, a sufficiently long hold time is given to prevent an error operation, and on the other hand, to the operation switch of a shorter operation time, a shorter hold time is given to make it possible to operate the responding appliance.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display control device for operation switches that control the operation of electrical components.

[Prior Art] Traditionally, radio receivers, audio sets, air conditioners, etc. have been widely known as electrical components installed in vehicles such as automobiles, but in recent years, in addition to these, televisions Vehicle-mounted receivers, telephone devices, navigation systems, and the like have also been put into practical use.

When installing a large number of these electrical components, it is difficult to operate if each electrical component has its own control panel, and all of the above electrical components are placed near the driver's seat in a vehicle with limited space. It is impossible to do so.

For this reason, it has been considered to standardize the operating parts and display parts for operating status, etc. of each electrical component.
In JP 121142, a group of function keys is provided so that the type of electrical equipment to be controlled can be selected.
A system has been proposed in which the operation keys for all electrical components are shared, so that the operating sections of all electrical components can be installed in one place.

In addition to displaying the operation switches for each electrical component on the TV screen, for example, infrared sensors are placed around this screen so that the search lines intersect vertically and horizontally, and the display part of the operation switch on the screen is 2. Description of the Related Art A display control device for an operation switch is known in which an electrical component is operated by a matrix signal from an infrared sensor that detects a direct touch with a finger. In this display control device, by changing the screen display, it is possible to use a common operating section and an operating state display section for a large number of electrical components.

[Problem to be solved by the invention] By the way, in the case of the above-mentioned in-vehicle television receiver, the screen size cannot be made too large due to space constraints, etc., and in order to ensure maneuverability and forward visibility, Generally, the television set is located far below the driver's eye level.

Therefore, when operating the operation switch displayed on the television screen by touch, the operation switch that the driver sees on the display screen 50 projected by a cathode ray tube 52 (CRT), for example, as shown in FIG. 5
3 on the screen 50 and the screen 50 of the operation switch 53
There may be a deviation between the actual position above and the user intending to operate the operation switch 53, but end up touching the operation switch 54 located above the switch 53. Until the calling time of the electrical component activated by this erroneously operated switch 54 has elapsed, inputs from other operation switches will not be accepted, and inputs cannot be made by operating the operation switch 53 again. ,
In particular, when the call time is long, there is a problem that a long time loss occurs.

For this reason, it is known that the display color of the input operation switch is changed to a specific color when the input is performed manually, so that the input operation switch can be easily seen, but even in this case, the display color Since the electrical components have already been activated by the time the operator visually recognizes the input operation switch due to the change in , it is impossible to prevent loss time due to erroneous operation of the switch, as in the case described above.

To solve this problem, a hold time is set for the operation of the operation switch, and the operation switch is held for a certain period of time (hold time).
u.It may be possible to prevent erroneous switch operation by setting the electrical components so that they do not operate unless the input is continued, but if the above hold time is set uniformly for each electrical component, This cannot be done in the case of electrical components whose operating time is shorter than the hold time, and if the above hold time is set shorter than the shortest operating time of all electrical components, the hold time may The problem was that it was too short and it was not possible to sufficiently confirm the input operation switch.

This invention has been made in view of the above problems, and when inputting and operating operation switches that are set on a display means and that control a plurality of electrical components each having a different operating time,
It is an object of the present invention to provide a display control device for an operation switch that can prevent erroneous operation of an operation switch for an electrical component that has a long operating time, and can also be used for electrical components that have a short operating time. purpose.

[Means for Solving the Problems] Therefore, the present invention provides an operation switch display control device in which operation switches for controlling a plurality of electrical components having different operating times are set on a display means. An operation switch detection means for detecting which operation switch among a plurality of set operation switches has been input, an input duration detection means for detecting the duration of input to the operation switch, and the input duration detection means and a comparison determination means for comparing the detection result with a predetermined time set for each operation switch,
Each of the operation switches can operate and control the electrical components only when an input is continuously made to the operation switch for the predetermined time period or more, and during the predetermined time period, the operation control is performed by each operation switch. These settings are made according to the operating time of each electrical component.

[Effects of the Invention] According to the present invention, it is possible to control the operation of electrical components only when each operation switch is continuously input for a predetermined period of time or more, and the predetermined period of time is set as the operating time of each electrical component. Therefore, for operation switches with a long operation time, a sufficiently long hold time is provided to prevent erroneous operation, while for operation switches with a short operation time, the above hold time is set. It can be shortened to enable that operation.

[Example] Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

As shown in FIG. 1, a display control device 1 for an operation switch according to the present embodiment includes a display device 2 configured of, for example, a CRT 2a (cathode ray tube), and a display screen 10 of the display device 2 to be changed and controlled. CRT controller 3 for
, a decoder 4 for detecting which switch among the plurality of operation switches displayed on the display screen IO has been input (touch operation), a control unit 5 composed of, for example, a microcomputer, and each electrical equipment. The video RAM 6 stores image processing data of operation switches for the product.

Electrical components such as a radio receiver 7 and a computer disc (CD) player 8 are connected to the control unit 5 so as to be able to send and receive signals, and the display device 2 is connected to a CRT controller 3 and a video RAM 6. is connected to the control unit 5 via the video RAM 6, and stores the image processing data created by the microcomputer of the control unit 5 in the video RAM 6, and also displays the data on the display screen IO of the display device 2 by the CRT controller 3 based on the stored data. A predetermined screen is displayed.

Around the display screen IO of the display device 2, as shown in detail in FIG. At the bottom of 10, there is an infrared receiver 12 for receiving the infrared light emitted from the infrared light emitter 11.
．． ..., 12 is the infrared light emitting section 11. ..., 11
is located opposite. This infrared light emitting section 11.・
. . , 11 and infrared receiving section 12. ..., 12 are provided not only in the vertical direction but also in the horizontal direction, and the infrared rays are emitted along the surface of the display screen 10 in parallel to each other in the vertical direction and the horizontal direction, respectively, in a state of crossing each other. When a part of the display screen 10 is touched, reception of infrared rays corresponding to that part is blocked, and the infrared receiving section 12. , 12 output a matrix signal to the decoder 4, and this output signal is processed by the decoder 4 and input to the control unit 5.

Therefore, when the operation switch of the image displayed on the display screen 1O is pressed and operated (touched), the operated switch is detected from the touched position, and the control unit 5 controls the video output according to the operation switch. R
A command signal is output to the AM 6 to call up a predetermined image, and the CRT controller 3 causes the CRT controller 3 to display this image on the display screen 10 of the display device 2. Alternatively, a command signal is output to the electrical component 7 or 8 in order to cause the electrical component 7 or 8 to perform a predetermined operation in accordance with the touched operation switch.

By the way, in this embodiment, in order to prevent a long time lost due to an erroneous input of the operation switch displayed on the display screen 10, each operation switch is operated manually. It is possible to control the operation of electrical components only when this is continued for a predetermined time (hold time) or more. The hold times are set to different values taking into consideration the system operation time of the electrical components controlled by each operation switch.

Hereinafter, detection of the input operation switch and detection of the duration of the input operation on the switch will be described with reference to the block diagram of FIG. 3.

The control unit 5 includes an operation switch detection circuit 14 that detects an input operation switch based on an output signal from the decoder 4, and an input duration detection circuit 15 that detects the duration of an input operation on the operation switch.
and a comparison/judgment circuit 16 that compares the detection result of the input duration detection circuit 15 with a hold time determined for the input operation switch.

And the display screen! When a certain operation switch on θ is input, as described above, the infrared receivers I2, . . . , +

At the same time, the output signal of the decoder 4 is input to the input duration detection circuit 15, and detection of the duration of the manual operation of the operation switch is started. Then, when the input operation for the operation switch is completed, the detection result of the input duration time is input to the comparison judgment circuit 16, and the comparison judgment circuit 16 compares the hold time determined for the input operation switch and the The detection result of the human power duration detection circuit 15 is compared, and only when the detection result is longer than the hold time, the operation of the electrical component by the operation switch is started.

Note that by touching the mode switch, the display screen 10 of the display device 2 according to this embodiment returns to the basic screen and displays the radio receiver 7 or the CD on this basic screen.
It is possible to select any of the electrical components such as the player 8 and display an image of its operation switch. In addition, in this embodiment, the navigation system software is stored on a compact disk (CD), and the software of the navigation system is stored on a compact disk (CD).
By replacing D, the CD player 8 can be operated.

Hereinafter, specific examples of the present invention will be described.

For example, when the display screen of the operation switch of the radio receiver 7 is called up, as shown in FIG. 4, the PM/AM changeover switch 21. An automatic channel selection switch 22, frequency change switches 23 and 24, volume adjustment switches 25 and 26, a frequency display section 27, and a mode switch 20 are displayed. For example, when the automatic tuning switch 22 is selected and touched, the automatic tuning system automatically searches for frequencies of receivable broadcasting stations, and displays them on the frequency display section 27 in descending order of radio wave frequencies. .

The operating time of this system is 30 seconds. Further, when the frequency change switch 23 or 24 is selected, the receiving frequency of the radio tuner is increased by 0.1 MHz.

In this case, the system operating time is 3 seconds.

When the mode switch 20 is operated to call up the operation switch screen of the navigation system, as shown in FIG. A map forwarding switch 33 for moving the map, a map enlargement switch 34 for enlarging and displaying a part of the displayed map, and the mode switch 20 are displayed. For example, by selecting and touching the reset switch 32, another map can be displayed in place of the currently displayed map. In this case, the system operating time is 60 seconds. Furthermore, when the map forwarding switch 33 is selected, the map can be moved in one second of operation time.

Furthermore, when the mode switch 20 is operated to call up the operation switch screen of the CD player 8, as shown in FIG.
, a track change switch 37 for changing the CD track, and the mode switch 20 mentioned above are displayed. The system operating times for the disk exchange and track change are 20 seconds and 10 seconds, respectively.

In this embodiment, as described above, a hold time is set for each operation switch, and as shown in Table 1, this hold time has a different value ( For example, it is set to 1/10 of each system operating time.

That is, if a hold time is not provided as in the conventional case, for example, when operating the radio receiver 7 (see FIG. 4), the user intends to operate the frequency change switch 23 to change the frequency. If the automatic tuning switch 22 is operated by mistake, input from other operation switches will not be accepted until the operating time (30 seconds) of the automatic tuning system has elapsed, and the frequency change switch 23 will not be accepted.
It was not possible to perform the operation again.

In this embodiment, since the above-mentioned hold time is provided, you can check the operation switch you operated within this hold time, and if you make a mistake, you can operate it again. This can prevent a long period of lost time from occurring.

Furthermore, even if a hold time is provided, if the hold time is set uniformly regardless of the difference in system operating time of each operation switch as in the past, this hold time is set to the shortest system operating time (i.e., It is necessary to set the hold time of the navigation system's map feed operation switch to a value less than 1 second (operating time), but this is too short. For this reason, it has not been possible to substantially cope with the case where there is an operation switch with a short system operating time as described above.

In this example, the hold time for each operation switch was set according to the system operating time (
(Refer to Table 1), a sufficiently long hold time is provided for operation switches whose system operation time is long to prevent erroneous operation, and the above-mentioned hold time is provided for operation switches whose system operation time is short. It is possible to shorten the time and make the operation possible.

In the above embodiment (hereinafter referred to as the first embodiment), the hold time for each operation switch is different for each switch, so the occupant who inputs and operates these operation switches,
It is necessary to memorize the hold time for each operation switch. In order to eliminate this inconvenience, it is possible to notify the occupants that the hold time has elapsed using a buzzer or the like.

A second embodiment of the present invention will be described below.

That is, in this embodiment, although not specifically shown, the comparison judgment circuit 1 provided in the control unit 5
6 (see Figure 3) and starts detecting the input duration when the operation switch is manually operated.When the time measured by the input duration detection circuit 15 (timer) exceeds the hold time of the operation switch, The above buzzer is activated when the

Further, in this embodiment, the display color of the input operation switch is changed to a specific color (for example, green) at the time of input, so that it is easy to visually recognize which operation switch has been input.

Hereinafter, the operation of the operation switch display control device according to this embodiment will be explained based on the flowchart of FIG. 7. In the following explanation, the same parts as in the first embodiment are given the same reference numerals, and further explanation will be omitted.

First, when a certain operation switch on the display screen IO is touch-operated in step #1, the operation switch detection circuit 1
4, detection of the input operation switch is performed. Based on this detection result, the display color of the operation switch on the display screen 10 is changed in step #3. Then, a timer is started in step #4, and step #5
A determination is made as to whether or not another operation switch is being touched.

If the result of this judgment is YES, the process returns to step #3 and the display colors of the other operation switches are also changed. That is, by changing the color of two or more operation switches, the occupant is alerted to redo the input operation.

In this case, no input is accepted for any of the operation switches.

If the determination result in step #5 is No, then in step #6, the comparison and determination circuit 16 determines whether or not the time measurement result by the timer exceeds the hold time of the input operation switch. A comparative judgment is made.

If the determination result is YES, a buzzer is activated in step #7, and then, in step #8, system operation of the electrical components to be controlled by the input operation switch is started. Also, the determination result in step #6 above is N
In the case o, that is, when the input duration time has not reached the hold time, the process returns to step #5 and the timer continues measuring the manual input duration time.

As explained above, according to this embodiment, the timer measures the duration of input to the operation switch, and if this input duration exceeds the hold time of the operation switch, the buzzer is activated. Therefore, the occupant does not need to memorize the hold time for each operation switch, and the operability of the operation switch display control device can be improved.
