Controller of air conditioning system for vehicle {CONTROLLER OF AIR CONDITIONING SYSTEM FOR AUTOMOTIVE VEHICLES}

The present invention relates to a controller of an air conditioner for a vehicle, and more particularly, variously changing the lighting color of a lighting device for lighting a display unit and a mood lamp, etc., and "changing the lighting color" of the lighting device as necessary. The present invention relates to a controller of an air conditioner for a vehicle capable of stopping the change of the lighting color of the lighting device when the user does not want to by configuring it to be released.

In recent years, the interior of the car interior has been regarded as very important. This is because the interior of the vehicle interior has a great influence on the purchase of a vehicle by a consumer. Accordingly, vehicle manufacturers are developing various methods for improving the interior of a vehicle interior.

As a method for improving the interior of a vehicle interior, there is a method of improving lighting devices of a controller for an air conditioner. As an example, as shown in FIG. 1, there is a technique of variously changing the lighting colors of lighting devices (not shown) that illuminate a specific part of the controller, for example, the mood lamp 1.

This technology is configured to variously change the lighting color of the mood lamp 1 according to the driving condition of the vehicle and the driving environment. For example, it is configured to variously change the lighting colors of the lighting devices based on the "set temperature" in the vehicle interior, the "discharge air temperature" in the vehicle interior, or the "discharge air volume in the vehicle interior".

Therefore, it is possible to improve the atmosphere and interior of the vehicle interior, and through this, the marketability of the vehicle is remarkably improved.

However, this conventional lighting color changing technology is a structure that always changes the lighting color of the lighting device regardless of the user's preference and taste, so even if the lighting color change of the lighting device does not suit the user's taste and preference, it can be accommodated as it is. There is only one drawback.

And because of this disadvantage, a problem has been pointed out that the user is very inconvenient. In particular, there is a disadvantage in that the driver is visually stimulated due to the change in the lighting color of the lighting device, and this disadvantage is pointed out that it interferes with the driver's safe driving.

The present invention has been conceived to solve the conventional problems as described above, and its purpose is to limit the "lighting color change" of the lighting device as necessary, so that the "lighting device" in case the user does not want to It is to provide a controller of an air conditioner for a vehicle that can cancel "change of lighting color".

Another object of the present invention is to provide a controller of a vehicle air conditioning apparatus capable of solving the disadvantages caused by changing the lighting color by configuring the user to cancel the "lighting color change" of the lighting device when the user does not want it. .

In order to achieve this object, the controller of the vehicle air conditioning apparatus according to the present invention is a controller of an air conditioning apparatus for a vehicle including a symbol of each switch, a display unit, and a plurality of lighting devices respectively illuminating a mood lamp. Among the plurality of lighting devices, a specific lighting device selected in advance is variously changed in lighting color according to a specific vehicle environment condition; An illumination color change canceling and return mode entry unit capable of entering an illumination color change canceling mode for canceling a change of the illumination color of the specific lighting device or an illumination color change returning mode for resetting; When entering the lighting color change cancellation mode by the lighting color change cancellation and return mode entry unit, the specific lighting device is controlled to limit the change of lighting color, and when entering the lighting color change return mode And a control unit that controls the specific lighting device to allow the change of the lighting color.

Preferably, the lighting color change canceling and return mode entry part is composed of a combination of two specific button-type switches among a plurality of switches installed in the controller, and while the lighting color of the specific lighting device is changed, the user When the two button-type switches are operated according to a preset combination condition, outputs a lighting color change canceling mode entry signal; In a state in which the lighting color change of the specific lighting device is stopped, when the user re-manipulates the two button-type switches according to a preset combination condition, the lighting color change return mode entry signal is output.

And, when the lighting color change canceling mode entry signal is output from the lighting color change canceling and return mode entry unit, the controller enters the lighting color change canceling mode and restricts changing the lighting color of the specific lighting device; When the lighting color change return mode entry signal is output from the lighting color change canceling and return mode entry unit, the lighting color change of the specific lighting device is allowed while entering the lighting color change return mode.

And the control unit, when entering the lighting color change canceling mode, after flashing the specific lighting device at a preset number of times at a preset time interval, limiting the change of the lighting color, and changing the lighting color When entering the return mode, the specific lighting device is flashed a preset number of times at a preset time interval, and then the lighting color is allowed to be changed.

According to the controller of the vehicle air conditioner according to the present invention, since it is a structure capable of limiting the "lighting color change" of the lighting device as necessary, the "lighting color change" of the lighting device can be canceled when the user does not want. It works.

In addition, since the "light color change" of the lighting device can be canceled if the user does not want to, the disadvantages of changing the lighting color, for example, visual stimulation of the driver and the resulting disturbance in safe driving are eliminated. There is an effect that can be done.

4 is a flowchart showing an example of the operation of the controller for an air conditioner according to the present invention.

Hereinafter, a preferred embodiment of a controller of an air conditioning apparatus for a vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

First, before looking at the features of the controller for an air conditioning apparatus according to the present invention, a brief look at the controller of the air conditioning apparatus with reference to FIGS. 2 and 3.

The controller of the air conditioner includes a housing 10, a plurality of switches 20 installed in the housing 10, a display unit 30, and a mood lamp 40.

The switch 20 controls a corresponding device by turning on or off a corresponding device while being turned on or off according to a user's manipulation, or by adjusting a detailed set value.

The display unit 30 displays an operating state of the air conditioner and a series of operation processes, and is displayed at a predetermined brightness by light sources (not shown) of the lighting device.

The mood lamp 40 includes a ring-type mood lamp 42 installed around the rotary switch 22 and a bar-type mood lamp 44 installed on the front part of the housing 10. There are, and these mood lamps 40 are equipped with lighting devices 46, respectively.

The lighting device 46 is composed of a plurality of LED light sources, and illuminates the mood lamp 40 while emitting light by an applied power source.

In addition, the controller of the air conditioner is configured to variously change the lighting color of the lighting device 46 of the lighting device of a specific part, for example, the mood lamp 40.

In particular, it is configured to variously change the lighting color of the mood lamp 40 according to the "set temperature" in the vehicle interior, the "discharge air temperature" in the vehicle interior, or the "discharge air volume in the vehicle interior". Therefore, it improves the atmosphere and interior of the vehicle interior.

Next, features of the controller for an air conditioner according to the present invention will be described in detail with reference to FIGS. 2 to 4.

First, referring to FIGS. 2 and 3, the controller of the present invention further includes a lighting color change canceling and returning means 50 capable of canceling or restoring the "lighting color change" of the lighting device 46. (In the present invention, as an example of a lighting device, the lighting device 46 of the mood lamp 40 will be described as an example.)

The lighting color change canceling and returning means 50 includes a lighting color change canceling and returning mode entry unit 60 and a control unit 70.

The lighting color change canceling and returning mode entry unit 60 is a mode for releasing the "lighting color change" of the lighting device 46 (hereinafter referred to as "lighting color change canceling mode 72") or returning it again To enter the mode (hereinafter referred to as "lighting color change return mode 74"), it is composed of a combination of two specific button-type switches among the plurality of switches 20 installed in the controller. For example, it is constituted by a combination of the auto mode switch 24 and the mode selection switch 26.

The lighting color change canceling and return mode entry unit 60 is, in a state in which "lighting color change" of the lighting device 46 is in progress (ON), of the auto mode switch 24 and the mode selection switch 26, When one is pressed and then the other is pressed more than a predetermined number of times within a preset time, a "illumination color change canceling mode entry signal S1" is output.

For example, when the auto mode switch 24 is pressed and the mode selection switch 26 is rapidly pressed four or more times within 2 seconds, a "light color change canceling mode entry signal S1" is output.

On the contrary, in the state in which the "lighting color change" of the lighting device 46 is released (OFF), the auto mode switch 24 is pressed, and then the mode selection switch 26 is quickly pressed four or more times within 2 seconds, the "lighting color change" It is configured to output a color change return mode entry signal (S2)".

The lighting color change canceling and return mode entry unit 60 of this structure is a mode capable of canceling or restoring the "light color change" of the lighting device 46 by pressing and combining predetermined specific switches according to predetermined conditions. To be able to enter.

Again, referring to FIGS. 2 and 3, the controller 70 is equipped with a microprocessor, and the "lighting color change canceling mode entry signal S1" is received from the lighting color change canceling and return mode entry unit 60. Upon input, it is determined that the user does not want to "change the lighting color" of the lighting device 46.

In response to this determination, the controller 70 enters the "lighting color change canceling mode 72", and the controller 70 that has entered the "lighting color change canceling mode 72", the lighting device 46 Control to release the "lighting color change" of the lighting device 46.

Accordingly, the "lighting color change" of the lighting device 46 is stopped, and at the same time, the lighting color of the lighting device 46 can be constantly controlled with only one specific color set in advance. This allows the user to limit the "lighting color change" of the lighting device 46 as necessary.

Here, when the "lighting color change canceling mode entry signal (S1)" is input from the lighting color change canceling and return mode entry unit 60, the controller 70 sets the lighting device 46 in advance at a preset time interval. After flashing a set number of times, it is preferable that the lighting device 46 is configured to cancel the "lighting color change".

For example, when the "lighting color change canceling mode entry signal (S1)" is input from the lighting color change canceling and return mode entry unit 60, the lighting device 46 flashes three times at 0.5 second intervals. After that, the lighting device 46 is configured to cancel the "lighting color change".

The reason for this configuration is that, by blinking the lighting device 46 a predetermined number of times at "when the lighting color change is canceled" of the lighting device 46, the user is informed in advance that the "lighting color change" of the lighting device 46 is released. It is to inform.

And the control unit 70, when releasing the "lighting color change" of the lighting device 46, controls the lighting color of the lighting device 46 to only one specific color set in advance, but does not change the color It is controlled in the same color as other lighting devices around it.

For example, the symbol 20a of the switches 20 and the background color of the display unit 30 are controlled to have the same color. Accordingly, the illumination color of the mood lamp 40 can be matched with both the color of the symbol 20a of the switches 20 and the background color of the display unit 30.

Again, referring to FIGS. 2 and 3, the control unit 70 is in a state in which the “lighting color change” of the lighting device 46 is released, and the “lighting color change” is canceled from the return mode entry unit 60. When the color change return mode entry signal (S2)" is input, it is determined that the user wants to "change the lighting color" of the lighting device 46.

And when such a determination is received, the controller 70 enters the "lighting color change return mode 74", and the controller 70 that has entered the "lighting color change return mode 74", the lighting device 46 Control to allow "changing the lighting color" of the lighting device 46.

Thus, it allows the "lighting color change" of the lighting device 46 to be restored. Accordingly, the lighting color of the mood lamp 40 can be variously changed according to specific conditions.

On the other hand, the control unit 70, when the "light color change return mode entry signal (S2)" is input from the lighting color change cancellation and return mode entry unit 60, the lighting device 46 in advance at a preset time interval. After flashing a set number of times, it is preferable that the lighting device 46 is configured to start "changing the lighting color".

For example, when the "light color change return mode entry signal (S2)" is input from the lighting color change canceling and return mode entry unit 60, the lighting device 46 flashes three times at 0.5 second intervals (點滅) After that, it is configured to start "changing the lighting color" of the lighting device 46.

The reason for this configuration is to inform the user that the "light color change" of the lighting device 46 is restored by blinking the lighting device 46 a predetermined number of times when the lighting device 46 "returns to the lighting color change" It is for sake.

Next, an operating example of the present invention having such a configuration will be described with reference to FIGS. 2 to 4.

First, an example of the operation of releasing the "lighting color change" of the lighting device 46 will be described.

4, 2, and 3, the air conditioner is turned on (S101), and the lighting color of the specific lighting device 46, for example, the lighting color of the mood lamp 40 is variously changed. In the current state (S103), it is determined whether the user has operated the combination of the switches 24 and 26 of the lighting color change release and return mode entry unit 60 according to a preset condition (S105).

For example, while pressing the auto mode switch 24, it is determined whether or not the mode selection switch 26 is quickly pressed four or more times within 2 seconds.

As a result of the determination, if the mode selection switch 26 is rapidly pressed four or more times within 2 seconds while the auto mode switch 24 is pressed, a "light color change canceling mode entry signal (S1)" is output (S107).

And if the "lighting color change canceling mode entry signal (S1)" is output, the controller 70 determines that the user does not want the "lighting color change" of the lighting device 46, and the "lighting color change canceling mode 72" )" (S109).

And the control unit 70, which has entered the "lighting color change canceling mode 72", flashes the lighting device 46 at a preset time interval at a preset number of times (S111), and then the "lighting device 46" The lighting color change" is released (S113).

For example, after blinking the lighting device 46 three times at 0.5 second intervals (S111), the "lighting color change" of the lighting device 46 is canceled (S113).

Then, while the "lighting color change" of the lighting device 46 is stopped, the lighting color of the lighting device 46 is constantly controlled with only one specific color set in advance.

Next, an example of the operation of returning the "lighting color change" of the lighting device 46 will be described.

4, 2 and 3, in a state in which the "lighting color change" of the lighting device 46 is released (S113), the user cancels the change of the lighting color and each switch of the return mode entry unit 60 ( 24, 26) It is determined whether the combination has been operated in accordance with a preset condition (S115).

For example, while pressing the auto mode switch 24, it is determined whether or not the mode selection switch 26 is quickly pressed four or more times within 2 seconds.

As a result of the determination, while the auto mode switch 24 is pressed, if the mode selection switch 26 is rapidly pressed four or more times within 2 seconds, a “light color change return mode entry signal (S2)” is output (S117).

And if the "lighting color change return signal S2" is output, the control unit 70 determines that the user wants the "lighting color change" of the lighting device 46 to enter the "lighting color change return mode 74". Enter (S119).

And the control unit 70, which has entered the "lighting color change return mode 74", flashes the lighting device 46 at a preset time interval at a preset number of times (S121), and then the "lighting device 46" The lighting color change" is restored (S123).

For example, after blinking the lighting device 46 three times at 0.5 second intervals (S121), the "lighting color change" of the lighting device 46 is restored (S123).

Then, as the "lighting color change" of the lighting device 46 starts again, the lighting color of the mood lamp 40 is variously changed according to specific conditions.

According to the controller of the present invention having such a configuration, since it is a structure capable of limiting the "lighting color change" of the lighting device as necessary, the "lighting color change" of the lighting device can be canceled when the user does not want. .

In addition, since the "light color change" of the lighting device can be canceled if the user does not want to, the disadvantages of changing the lighting color, for example, visual stimulation of the driver and the resulting disturbance in safe driving are eliminated. can do.

In the above, preferred embodiments of the present invention have been exemplarily described, but the scope of the present invention is not limited to such specific embodiments, and can be appropriately changed within the scope described in the claims.
