Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the preferred embodiments of the present invention will be described below, but it is needless to say that the technical idea of the present invention is not limited thereto and can be variously modified by those skilled in the art.

FIG. 3 is a conceptual diagram showing the configuration of a remote control device for a vehicle air conditioner according to the present invention, and FIG. 4 is a flowchart for explaining a remote control method for a vehicle air conditioner according to the present invention.

A remote control method for a vehicle air conditioner according to the present invention is characterized in that it is possible to determine whether a remote control is to be performed by detecting a temperature of a car room in advance of performing a remote air conditioner.

3, the remote control device for a vehicle air conditioner according to the present invention is an apparatus for remotely controlling an air conditioner for cooling and heating a vehicle. The remote control device includes a temperature sensor 10, a controller 20, a telematics A telematics unit 30 and a mobile communication terminal 40.

The in-vehicle temperature sensor 10 is a conventional INCAR SENSOR installed inside the vehicle to sense the temperature of the inside of the vehicle.

The controller 20 receives the vehicle room temperature information from the in-vehicle temperature sensor 10 and controls the air conditioner.

The telematics unit 30 is installed inside the vehicle so as to provide a wireless Internet service and performs CAN (Controller Area Network) communication with the controller 20.

For reference, the telematics unit 30 means a remote information unit for a vehicle, which can transmit and receive various kinds of information in real time based on an automobile through mobile communication, the Internet, car navigation, and the like. The CAN communication is a communication method in which a plurality of ECUs are connected in parallel to exchange data, and the CAN communication is applied to automobiles because it can withstand harsh environments, high temperatures, shocks, and vibration environments.

The mobile communication terminal 40 is provided with a predetermined remote air conditioning control application 41 for controlling the controller 20 after requesting the car room temperature information. The mobile communication terminal 40 is connected to the telematics unit 30 via a wireless Internet Lt; / RTI >

Accordingly, the driver can remotely control the air conditioner by determining whether to perform the remote air conditioning after receiving the car room temperature information from the outside using the mobile communication terminal 40 before boarding the vehicle.

At this time, the mobile communication terminal 40 means a terminal capable of mounting an application and capable of wireless communication, for example, a smart phone or an iPAD.

It is preferable that the controller 20 and the telematics unit 30 are capable of CAN communication using a battery before the vehicle starts.

This will be described in more detail as follows. In the conventional case, IGN1 is used as the recognition power source for the in-vehicle temperature sensor 10 and the CAN communication drive power source only when the vehicle is turned on. However, in the case of the present invention, a battery which is of the ignorable operation type is used as the recognition power source for the in-vehicle temperature sensor 10 and the CAN communication drive power source.

As shown in FIG. 4, the remote control method for a vehicle air conditioner according to the present invention first executes a remote air conditioner control application installed on a mobile communication terminal by a user (S10).

Then, the mobile communication terminal requests car room temperature information to the telematics unit through wireless communication between the mobile communication terminal and the telematics unit installed in the car (S20). For example, a user requests a car room temperature information by pressing a predetermined button in a remote air conditioning control application.

Then, the vehicle-room temperature information request is transmitted from the telematics unit to the controller through the CAN communication of the telematics unit and the controller that controls the air conditioner (S30). At this time, the controller and the telematics unit perform the CAN communication using the battery in the ignoring state in which the vehicle is not started.

Then, the controller receives the room temperature information from the in-vehicle temperature sensor and transmits it to the telematics unit through the CAN communication. The telematics unit transmits the room temperature information to the mobile communication terminal through the wireless communication (S40 , S50).

At this time, the car room temperature information sensed by the in-vehicle temperature sensor may be inaccurate because the blower is not driven for the vehicle side discharge due to neglect, so that the car room temperature information can be corrected as follows .

That is, in order to more accurately extract the car room temperature information, the car interior temperature at the vehicle start-off time, the current outside temperature at which the car room temperature information is requested from the telematics unit, the current solar radiation amount, The sensed car room temperature information can be corrected by reflecting the elapsed time until now.

f (the current temperature in the car) = f (elapsed time from the vehicle interior temperature at the time when the vehicle is turned on, the current outside temperature, the present solar radiation amount,

To be more specific, the elapsed time from the current outside temperature, the current solar radiation amount, and the vehicle start-off time to the present time can be configured as a table (T1, T2, T3 table respectively)

At this time, if the current outdoor temperature is equal to or higher than the vehicle interior temperature at the time when the vehicle is turned off at the present time as a result of comparison of the present indoor temperature with the current outdoor temperature and the vehicle start OFF time, Can be performed.

Vehicle room temperature = Vehicle start-OFF time Difference room temperature + T1 * T2 * T3

That is, when the outside air temperature is equal to or higher than the vehicle room temperature at the time when the vehicle is turned off, the vehicle occupancy temperature at the vehicle start-off time is calculated by appropriately using the current outside temperature, the present solar radiation amount, (+) To compensate the temperature (+).

On the other hand, when the present outside temperature is equal to or lower than the vehicle interior temperature at the time when the vehicle is turned off, it is possible to perform (-) temperature correction using the following equation.

Vehicle room temperature = Vehicle start-OFF time Difference room temperature -T1 * T2 * T3

That is, when the outside air temperature is equal to or lower than the vehicle room temperature at the time when the vehicle is turned off, the vehicle occupancy temperature at the vehicle start-off time is calculated by appropriately using the current outside temperature, the present solar radiation amount, (-) temperature correction by reflecting the value (-).

Finally, the user determines whether to perform the remote air conditioning based on the received car room temperature information (S60). That is, before performing the remote air conditioning, it is determined whether or not to perform the remote air conditioning after receiving the room temperature information in advance.

As described above, in the case of the remote control method for a vehicle air conditioner according to the present invention, it is possible to prevent the remote air conditioner from being unnecessarily performed, thereby improving the fuel economy and improving the commerciality.

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 exemplary embodiments. And various alternatives, modifications, and alterations can be made within the scope.

Therefore, the embodiments disclosed in the present invention and the accompanying drawings are intended to illustrate and not to limit the technical spirit of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments and the accompanying drawings . The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents should be construed as falling within the scope of the present invention.
