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

First, a description will be given of a remote air conditioning control technique with reference to FIG. 1, before a characteristic portion of a vehicle air conditioner according to the present invention is examined.

The remote air conditioning control technology includes a remote control terminal 10 and an air conditioning control unit 30 that receives a control signal of the remote control terminal 10 and controls the air conditioning apparatus 20. [

The remote control terminal 10 is equipped with a wireless communication means 12, for example, a web browser capable of accessing the wireless Internet and a wireless Internet access program (WiBro, WiFi) .

The remote control terminal 10 incorporates an "air conditioning control application" which is an "air conditioning control application program", and the "air conditioning control application" is configured to be downloaded from an application store after being purchased.

The air conditioning control unit 30 is equipped with a wireless transmitting / receiving unit 32 and is connected to the remote control terminal 10 through the wireless communication means 12.

The air conditioning control unit 30 receives a control signal wirelessly transmitted from the remote control terminal 10, for example, an air conditioner " ON signal "and a control signal such as & , And controls the air conditioner 20 according to the received control signal.

Particularly, according to the "set temperature", the evaporator 40 or the heater 42 of the air conditioner, the blower 44, the intake door 45, the temp door 47, Mode Door (49). Therefore, before the driver gets on the vehicle, the interior of the car is cooled and heated comfortably in advance.

Next, the features of the air conditioner for a vehicle according to the present invention will be described in detail with reference to Figs. 1 and 2. Fig.

Referring first to FIG. 1, the vehicle air conditioner of the present invention includes a high-temperature environment discriminating means 50 for discriminating whether or not a current temperature environment of a vehicle is a high-temperature environment in which an air conditioner must operate.

The high temperature environment discrimination means 50 comprises a date calculation clock 52 for calculating the current year, month and day and a high temperature environment discrimination means 50 for discriminating the current indoor and outdoor environment And a microcomputer 54 for determining whether or not the air conditioner should be operated in a high temperature environment.

The date calculation clock 52 is composed of a clock installed in the vehicle, for example, a built-in clock of a navigation system, and calculates the current year, month, and day, To the microcomputer (54).

The microcomputer 54 is equipped with a microprocessor. When the current date is input from the date calculation clock 52, the microcomputer 54 determines whether the current date inputted is within a predetermined date range.

As a result of the determination, when it is within the "set date range", it is determined that the present indoor / outdoor temperature environment is a high temperature environment in which the air conditioner must operate, and a "high temperature environment signal S1" is output. And outputs it to the air conditioning control unit 30 in particular.

Here, it is preferable that the "set date range" built in the microcomputer 54 is set to June to August, which is known as the summer period of high temperature.

On the other hand, when the "high temperature environment signal S1" is inputted from the high temperature environment judging means 50, the air conditioning control unit 30 judges whether the "remote control signal" of the air conditioner is inputted from the remote control terminal 10 . Particularly, it is judged whether the air conditioner "ON signal"

As a result of the determination, when the air conditioner "ON signal" is simultaneously input from the remote control terminal 10 in the state that the high temperature environment signal S1 is input, It is determined that it is necessary to cool the inside of the vehicle to the maximum (Max) when the air conditioner 20 is remotely controlled.

In accordance with this determination, the air conditioning control unit 30 enters the "remote high temperature environment cooling mode ". The air conditioning control unit 30 which has entered the "remote high temperature environment cooling mode " unconditionally forcibly turns on the evaporator 40 of the air conditioner and sets the intake door 45 to the" The hot air inlet 45a is opened and the temp door 47 is forcedly controlled to the " maximum cooling position (C) " To the maximum state.

Thus, the air in the vehicle interior is cooled while being circulated, and a large amount of the cooled air can be introduced into the vehicle interior. Thus, the interior of the vehicle is efficiently cooled.

As a result, the cooling performance of the passenger compartment is remarkably improved at the time of remote control. Particularly, the cooling performance of the interior of the vehicle is improved regardless of the user "set temperature ". Accordingly, it is possible to positively cope with the intention of the user who wants to cool the car interior coolly before boarding the vehicle. As a result, the convenience of the user and the comfort of the passenger compartment are improved.

On the other hand, when entering the "remote high-temperature environment cooling mode ", the air conditioning control unit 30 forcibly energizes the evaporator 40 of the air conditioner so that the" target temperature " It is desirable to set it low.

This is to increase the cooling performance of the evaporator 40 and to lower the temperature of the air blown into the passenger compartment, thereby improving the cooling performance of the passenger compartment.

More preferably, when the air conditioning control unit 30 enters the "remote high temperature environment cooling mode ", it is preferable to set the" target temperature "of the evaporator 40 to the" minimum temperature ". This maximizes the cooling performance of the evaporator 40 and minimizes the temperature of the air blown into the passenger compartment, thereby maximizing the cooling performance of the passenger compartment.

Referring again to FIG. 1, the air conditioner of the present invention further includes a user boarding detection means 60.

The user boarding detection means 60 includes a door sensor (not shown) for detecting opening of a door (not shown) by sensing that the user is boarding the vehicle.

The user boarding detection means 60 detects that a user such as a driver or a passenger boarded the vehicle and inputs the sensed "vehicle boarding signal S2" to the air conditioning control unit 30. [

On the other hand, when the " vehicle boarding signal S2 "is input by the user boarding detection means 60, the air conditioning control unit 30 determines that it is not necessary to remotely control the interior of the vehicle because the current user is boarded.

Then, according to this judgment, it is released from the "remote high temperature environment cooling mode" and enters the original "automatic control mode ".

The air conditioning control unit 30 which has entered the "automatic control mode " returns the evaporator 40, the intake door 45 and the tempo door 47 of the air conditioner to their original state. Therefore, the temperature of the vehicle interior can be automatically controlled according to the temperature and irradiation amount of the vehicle interior and exterior.

Next, an operation example of the present invention having such a configuration will be described with reference to Figs. 1 and 2. Fig.

First, when the user remotely turns on the air conditioner through the remote control terminal 10 (S101), the high temperature environment judging means 50 judges whether the current indoor / outdoor environment is a high temperature environment (S103).

As a result of the determination, if the inside / outside of the vehicle is in a high-temperature environment, the air conditioning control unit 30 determines that the current inside / outside of the vehicle is a high-temperature environment in which the air conditioner must operate and enters the "remote high- temperature environment cooling mode" (S105).

The air conditioning control unit 30 which has entered the "remote high temperature environment cooling mode " turns on the air conditioner, switches the intake door 45 to the " bet mode position B" Quot; maximum cooling position C "(S107).

Then, the air in the interior of the vehicle is cooled while being circulated, and a large amount of cooled air is introduced into the interior of the vehicle, thereby efficiently cooling the interior of the vehicle.

Thus, the cooling performance of the passenger compartment is remarkably improved at the time of remote control. As a result, it is possible to positively cope with the user's intention to cool the car interior coolly before boarding the vehicle.

On the other hand, the air conditioning control unit 30 determines whether the user has boarded the vehicle in the state of entering the "remote high temperature environment cooling mode " (S109).

As a result of the determination, if the user has boarded the vehicle, the air conditioning control unit 30 determines that it is not necessary to remotely control the interior of the vehicle since the current driver, passenger, or the like has boarded the vehicle.

In response to this determination, the operation mode is released to the " remote high temperature environment cooling mode ", and the operation returns to the original "automatic control mode" (S111).

Then, the evaporator 40, the intake door 45, and the tempo door 47 of the air conditioner are returned to their original state, and are automatically controlled according to the temperature and irradiation amount of the inside and outside of the vehicle.

According to the present invention having the above-described structure, since the interior of the vehicle is previously cooled through remote control, and when the indoor and outdoor environments are high temperature environment, the air conditioner is unconditionally turned on regardless of the set temperature, The comfort of the passenger compartment can be remarkably improved regardless of the set temperature at the time of control.

In addition, since the comfort of the interior of the vehicle can be remarkably improved regardless of the set temperature at the time of remote control, the intention of the user who wants to cool the interior of the vehicle coolly before boarding the vehicle can be positively coped with.

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.
