Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an idle stop air-

The present invention relates to an air conditioning apparatus for an idle stop vehicle, and more particularly, to an air conditioner for an idle stop vehicle, more particularly, to an air conditioner for an idle stop vehicle, which, when the vehicle is stopped, forcibly releases it from the "idle stop mode" The present invention relates to an idle stop air conditioner capable of preventing a user from being confused by forced release of the "idle stop mode ".

In recent years, various eco-friendly vehicles having high fuel efficiency and low emission of exhaust gas have been developed. As an example, there is an idle stop & go (ISG) vehicle.

The idle stop vehicle is a vehicle that prevents idling of the engine. The idle stop vehicle stops the engine while entering the "idle stop mode" when the vehicle is stopped by a traffic signal or the like and releases the idle stop mode when the vehicle restarts. And then restart the engine.

Such an idle stop vehicle prevents idling of the engine, so that unnecessary fuel consumption can be reduced and exhaust gas emissions can be reduced. Therefore, the fuel consumption of the vehicle is increased and air pollution is reduced.

On the other hand, in the idle stop vehicle, when the vehicle is stopped and enters the "idle stop mode", the engine is stopped and the air conditioner stops operating. .

In particular, in summer, the temperature of a vehicle interior rapidly rises due to the stop of the air conditioner caused by the stop of the vehicle, and in winter, the temperature of the vehicle interior is likely to be rapidly lowered due to the stopping of the heater due to the stop of the vehicle. Therefore, when the vehicle is stopped, there is a high possibility that the ride environment of the inside of the vehicle is deteriorated.

In order to solve this problem, when the evaporator temperature of the air conditioner rises above the "set temperature" under the high temperature condition after the "idle stop mode" Quot; idle stop mode ".

Therefore, even if the vehicle is stationary, if the temperature of the vehicle interior rises or falls and the ride environment of the vehicle interior deteriorates, the air conditioner or the heater of the air conditioner can be forcibly operated. Thus, the temperature of the passenger compartment can be maintained comfortably even when the vehicle is stationary.

On the other hand, when the "DEPOGGING DEVICE" is turned ON to remove the fogging of the window glass after the "idle stop mode" has been entered, or when the user manually turns on the air conditioner , Or to force the engine to be reactivated while being forcibly released from the "idle stop mode " even when the user manually raises the" blower speed "

Therefore, when the "defogging device" is turned on, or when the user turns on the air conditioner, or when the user raises the "blower speed" of the air conditioner, the air conditioner or the heater is forced .

Thereby, even if the vehicle is stationary, it is necessary to remove the fogging of the windowpane, or if the user wants to cool or heat the inside of the car, he or she can positively cope with it.

However, such a conventional idle stop vehicle is disadvantageous in that, when the idle stop mode is forcibly released and the engine is restarted in a state where the vehicle is stopped, the driver mistakenly thinks that the vehicle is malfunctioning or malfunctioning.

Particularly, the driver has the disadvantage that the vehicle is malfunctioning or malfunctioning due to the judgment that the "idle stop mode" is erroneously released despite the fact that the vehicle must be kept in the "idle stop mode" because the vehicle is stationary.

More specifically, when the vehicle is forcibly released from the "idle stop mode " by the" forced release condition "of the" idle stop mode "under the condition that the vehicle is stationary, for example, Set temperature "has elapsed or the" set time "has elapsed under a low temperature condition, or the" DEPOGGING DEVICE "has been turned ON, or the user manually turned on the air conditioner, If the "blower speed" is manually raised, the vehicle is released from the "idle stop mode" and the engine is restarted.

At this time, the driver judges that the "idle stop mode" is erroneously released despite the fact that the vehicle is stationary and therefore must maintain the "idle stop mode ". There is a problem in that the vehicle is malfunctioning or malfunctioning due to such judgment.

SUMMARY OF THE INVENTION The present invention has been conceived in order to solve the above-mentioned conventional problems, and an object of the present invention is to provide a vehicle control system and a vehicle control method thereof, in which a vehicle is forcedly released from an "idle stop mode" Stop mode "is forcibly released to the user when the" idle stop mode "is forcibly released.

It is another object of the present invention to provide an idle stop mode which can prevent a user from being confused by forced release of the "idle stop mode" by configuring the user so that the "idle stop mode" And an air conditioner for a vehicle.

In order to achieve the above object, the air conditioning system for an idle stop vehicle according to the present invention stops the engine, the air conditioner and the heater while entering the idle stop mode at the time of stopping the vehicle, When the engine, the air conditioner and the heater are re-operated and the specific idle stop mode forcibly released condition is satisfied after entering the idle stop mode, even when the vehicle is stopped, the engine, the air conditioner, A control unit for outputting an idle stop mode forcibly releasing notification signal when the vehicle is forcibly released from the idle stop mode after entering the idle stop mode; And an idle stop mode forcibly canceling notifying means for outputting a specific signal to notify the user that the current idle stop mode is forcibly released when the idle stop mode forcible cancellation notice control signal is inputted from the control unit do.

Preferably, the idle stop mode forcibly canceling notifying means is a display portion of the controller for controlling the air conditioner, and when the forcible cancellation is canceled from the idle stop mode, the control portion outputs the idle stop mode forcibly canceling notifying control signal The illumination of the display unit is blinked a predetermined number of times at predetermined time intervals.

The condition for forcibly releasing the idle stop mode after entering the idle stop mode is a condition that the evaporator temperature of the air conditioner is raised to a predetermined temperature or higher under a high temperature condition; A condition that a predetermined time has elapsed under a low temperature condition; A condition that the defogging apparatus is turned on automatically or manually by the user in order to remove the fogging of the window glass; A condition of whether the user manually turned on the air conditioner (ON); The condition of whether the user has increased the number of rotations of the blower; The control unit is forcibly released from the idle stop mode and restarts the engine, the air conditioner, and the heater when any one of the above conditions is satisfied.

The control unit controls the display unit to blink when the idle stop mode is forcibly released, and controls the illumination colors of the display unit differently according to the forced release conditions of the idle stop mode.

If the idle stop mode forced release condition is forcibly released from the idle stop mode under the condition that the temperature of the evaporator rises above the set temperature under the high temperature condition, the control unit controls the illumination color of the display unit to be blue ; Wherein if the idle stop mode forced release condition is forcibly released from the idle stop mode under a condition that a set time elapses under a low temperature condition, the illumination color of the display unit is controlled to be an orange system; If the idle stop mode is forcibly released from the idle stop mode by the ON condition of the defogging apparatus or the ON condition of the air conditioner or the blower raising condition of the blower among the idle stop mode forcible release conditions, And the color is controlled by a white system.

According to the air conditioner for an idle stop vehicle according to the present invention, since the display portion of the controller is blinked when the vehicle is stopped and when the vehicle is forcibly released from the "idle stop mode" Quot; stop mode "is forcibly released.

Further, since the user can be informed that the "idle stop mode" is forcibly released despite the vehicle being stopped, it is possible to prevent the user from being confused by forced release of the "idle stop mode"

Further, since the display unit of the controller blinks at the time of forced release of the "idle stop mode", the illumination colors of the display unit are controlled differently according to the "forced release condition" of the "idle stop mode" There is an effect that the reason for "forcible release" of the "idle stop mode" can be recognized through the illumination color of the controlled display unit.

Particularly, when the user grasps the color of the display unit to be blink-controlled, it is possible to recognize the "forced release" reason of the "idle stop mode" as "forced release condition". Therefore, there is an effect that the confusion of the user due to the forced release of the "idle stop mode" can be more positively prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of an air conditioner for an idle stop vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

First, an air conditioning apparatus for an idle stop vehicle will be briefly described with reference to FIG. 1 before a characteristic portion of an air conditioner for an idle stop vehicle according to the present invention will be described.

The air conditioner for an idle stop vehicle includes a control unit (10). The control unit 10 is equipped with a microprocessor. When the control unit 10 detects that the current vehicle is stopped from the idle stop detecting unit 20, for example, the transmission sensor, the control unit 10 enters the idle stop mode, Stop.

Conversely, if it is detected that the vehicle is traveling again from the transmission sensor of the idle stop detecting means 20, the engine 30 is released while being released from the "idle stop mode ".

On the other hand, the control unit 10 includes detection means 40 (hereinafter referred to as "idle stop mode forcible release condition detection means ") for detecting whether or not a condition for forcibly releasing the" idle stop mode "Quot; idle stop mode forcible release condition signal S1 ") is inputted from the idle stop mode control unit 40 (hereinafter abbreviated as " idle stop mode"), the engine 30 is forcibly released from the "idle stop mode "

Thus, the evaporator 50 or the heater 52 of the air conditioner can be operated even though the vehicle is stationary. Thus, the temperature of the passenger compartment can be maintained comfortably even when the vehicle is stationary.

Normally, the idle stop mode forcibly released condition detecting means 40 judges whether the temperature of the evaporator 50 rises above the "set temperature" under the high temperature condition after entering the " idle stop mode " (Refer to FIG. 2) which can manually turn on the air conditioner, a controller 60 for controlling the air conditioner to manually turn on the air conditioner, An air conditioner on / off switch 62 of the air conditioner control controller 60 and an air condition adjusting switch 64 of the air conditioner controller 60 (see FIG. 2) capable of manually adjusting the number of rotations of the blower 54.

When the temperature of the evaporator 50 rises above the "set temperature" under the high temperature condition after the entry into the "idle stop mode", or when the "set time" passes under the low temperature condition, Condition signal S1 "

The defogging apparatus outputs "idle stop mode forced release condition signal (S1) " while being turned on automatically or manually by the user at the time of occurrence of fogging of the window glass.

The air condition ON / OFF switch 62 outputs the "idle stop mode forced release condition signal S1" when the user presses the air conditioner to turn ON the air conditioner after entering the "idle stop mode".

When the user presses the blower 54 to raise the number of revolutions of the blower 54 after entering the idle stop mode, the air flow rate adjustment switch 64 outputs the "idle stop mode forced release condition signal S1".

The idle-stop mode forcibly canceling condition detecting means 40 having such a configuration is a well-known technique, and a detailed description thereof will be omitted.

Next, a feature of the air conditioner for an idle stop vehicle according to the present invention will be described in detail with reference to FIGS. 1 and 2. FIG.

1, the air conditioner of the present invention includes a control unit 10, wherein the control unit 10 receives from the idle stop mode forcibly cancel condition detecting unit 40 an idle stop mode forcibly cancel condition signal (S1) "is inputted, it is forcibly released from the " idle stop mode " and is configured to output the" idle stop mode forced release notification signal S2 ". To the idle-stop mode forcibly canceling notifying means 70, which will be described later.

The air conditioner of the present invention is provided with the idle stop mode forcibly releasing means (70).

The idle stop mode forcible release notification means 70 includes a liquid crystal display portion 72 of the controller 60 for controlling the air conditioner, as shown in Fig.

When the "idle stop mode forcible release notification control signal S2" is inputted in the control unit 10, the liquid crystal display unit 72 of the controller 60 blinks the background light according to the inputted control signal, Respectively.

In particular, the control unit 10 is configured to be flickered by a predetermined number of times at predetermined intervals. For example, three blinks at 0.5 second intervals.

Therefore, the user is informed that the current "idle stop mode" is forcibly released. In particular, it notifies the user that the "idle stop mode" is forcibly released despite the vehicle being stopped.

This allows the user to recognize the forced release of the "idle stop mode" when the vehicle is stationary. As a result, the user can be prevented from being confused by the forced release of the "idle stop mode "

On the other hand, at the time of forcible release of the "idle stop mode", the control unit 10 not only controls the liquid crystal display unit 72 of the controller 60 to blink, but also controls the " And the illumination colors of the display unit 72 are controlled differently.

That is, when the temperature of the evaporator 50 is forcibly released from the "idle stop mode" under the condition that the temperature of the evaporator 50 is raised to the "set temperature" under the high temperature condition in the "idle stop mode forced release condition" And controls the illumination color of the portion 72 in the blue system.

Therefore, when the temperature of the evaporator 50 is forcibly released from the "idle stop mode " under the condition that the temperature of the evaporator 50 is raised to the set temperature or higher under the high temperature condition, And is controlled to be flickered three times at intervals.

If the control unit 10 is forcibly released from the "idle stop mode " under the condition that the" set time "elapses under the low temperature condition in the" idle stop mode forced release condition ", the control unit 10 sets the illumination color of the display unit 72 It is controlled by the orange system.

Accordingly, the control unit 10 controls the orange liquid crystal display unit 72 to flicker three times at intervals of 0.5 seconds when the control unit 10 is forcibly released from the " idle stop mode "

In addition, the control unit 10 determines whether or not the condition for forced release from the " idle stop mode "or the condition that the user turns on the air conditioner by the " idle stop mode forced release condition" Stop mode "by the condition that the user is forcibly released from the " idle stop mode " by the user or by the condition that the user raises the number of revolutions of the blower 54, For example, it is controlled by a white system.

Therefore, when the forced release from the "idle stop mode" has been forcibly canceled by the ON condition of the defogging apparatus or the ON condition of the air conditioner or the condition for raising the number of revolutions of the blower 54, The liquid crystal display unit 72 is controlled to flicker three times at intervals of 0.5 seconds.

Meanwhile, the liquid crystal display unit 72 of the controller 60 is generally equipped with a multicolor light emitting diode as a background lighting apparatus, and these multicolor light emitting diodes emit light of various colors under the control of the control unit 10. [

According to the present invention having such a configuration, since the display unit 72 of the controller 60 is flickered when the vehicle is stopped and the vehicle is forcibly released from the "idle stop mode" The user can clearly recognize that the "idle stop mode" has been forcibly released.

In addition, since the user can be informed that the "idle stop mode" has been forcibly canceled despite the vehicle being stopped, the user can be prevented from being confused by the forced idle release in the " idle stop mode "

The present invention is also applicable to a case where the display unit 72 of the controller 60 is blinked at the time of forcible release of the "idle stop mode", and the display unit 72 of the "idle stop mode" It is possible to recognize the reason for "forcible release" of the "idle stop mode " through the illumination color of the display section 72 which is controlled to be blinked.

Particularly, when the user grasps the color of the display unit 72 to be blink-controlled, it is possible to recognize the "forced release" reason of the "idle stop mode" as the "forced release condition". Therefore, it is possible to more positively prevent the confusion of the user due to the forced release of the "idle stop mode ".

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
