Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle HVAC control system and a vehicle HVAC control system using weather information and an AVN unit,

The present invention relates to a vehicle HVAC control system in which weather information and an AVN unit are linked and a method of controlling a vehicle HVAC using the same. More specifically, in the process of controlling an HVAC unit of a car that is being parked in an indoor parking lot including a basement, By reflecting the temperature value, it is possible to use the electric power of the vehicle more efficiently. In addition, it is possible to drive the HVAC unit of the vehicle according to the environment outside the parking lot rather than the indoor parking lot, The present invention relates to a vehicle HVAC control system in which weather information and an AVN unit are linked with each other, and an automobile HVAC control method using the same.

The HVAC unit is equipped with an air conditioning system (HVAC System, Heating, Ventilation, and Air Conditioning System) to provide a comfortable environment for passengers in various climatic and driving conditions. Accordingly, the heater, the air blowing fan, and the air conditioner are appropriately driven so that the temperature and the air flow inside the vehicle can be adjusted. Of course, the driver of the vehicle is configured to selectively drive the heater, blower, and air conditioner by directly adjusting the controller of the HVAC unit according to weather conditions and the like.

In recent years, AVN units (Audio, Video, Navigation Units) are increasingly mounted on automobiles so that various kinds of operation information can be provided through monitors installed in a vehicle interior. The AVN unit is a system in which audio, video, and navigation devices are integrally integrated. The AVN unit is a system in which an image, a TV image, and a navigation guide image of navigation are recorded on a video recording medium such as a CD-ROM or a DVD- Images of other standards or the like can be displayed.

On the other hand, a considerable level of power consumption is required for driving the above-described HVAC unit and AVN unit. Accordingly, in the case of an electric vehicle in which an engine is driven using electric power previously charged in a battery rather than a gasoline engine or a diesel engine mounted battery in which the battery is charged during the operation of the vehicle, an electric device such as an HVAC unit and an AVN unit Efficient use of the power used can be a more sensitive issue.

However, in most HVAC units including conventional electric vehicles, there is a problem that the HVAC unit is unnecessarily wasted or the electric efficiency is lowered as the vehicle is started at the same time as the vehicle starts without appropriately reflecting the weather environment . That is, when the vehicle is parked in the parking lot or parked, the existing HVAC unit operates in a state where the temperature of the room where the vehicle was parked and the external temperature are not properly reflected, The situation in which it was used could have occurred.

For example, in the case where the temperature of the indoor sprung window is 20 ° C and the outside temperature is 10 ° C, it is generally considered that the operation of the air conditioner is unnecessary considering that the vehicle parked in the indoor parking space soon goes out. However, , The HVAC unit is automatically operated at the same time that the vehicle is started, thereby wasting battery power due to unnecessary operation of the air conditioner.

Also, when the temperature of the indoor parking lot is 10 degrees Celsius and the outside temperature is 30 degrees Celsius, the vehicle parked in a cool place soon goes out of the hotter temperature condition, so that the HVAC unit is operated from the front to drive the driver in a more pleasant environment However, in the case of conventional vehicles, since the air conditioner is automatically operated after the vehicle is outdoors or when the outside temperature is detected, or the air conditioner is suddenly operated by the driver's operation, the battery power is inefficiently used And the like.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic diagram of a weather information and automotive HVAC control system associated with an AVN of the present invention. FIG.
FIG. 2 is a flowchart showing a procedure of a method of controlling a vehicle HVAC using weather information of the present invention and an automobile HVAC control system associated with an AVN.

Hereinafter, weather information according to an embodiment of the present invention and a vehicle HVAC control system associated with an AVN unit and a vehicle HVAC control method using the same will be described in detail with reference to the accompanying drawings.

First, the weather information and the HVAC control system of the vehicle associated with the AVN unit will be described.

1 is a schematic representation of weather information of the present invention and a vehicle HVAC control system associated with an AVN unit.

Referring to FIG. 1, in the HVAC control system of an automobile in which the weather information and the AVN unit are linked with the weather information of the present invention, when the vehicle in a parked state is started, the temperature of the vehicle interior and the vehicle exterior are measured, HVAC unit 40 is included. Since the HVAC unit 40 is for controlling the temperature and the air volume of the vehicle interior, it is natural that the HVAC unit 40 is installed in the vehicle, and a detailed description of the specific structure will be omitted.

In addition, the HVAC control system of the vehicle in which the weather information and the AVN unit are connected according to the embodiment of the present invention includes an AVN unit 30 mounted on the vehicle for providing audio, video and navigation information to the driver and the passenger of the vehicle do.

In particular, the AVN unit 30 applied to the embodiment of the present invention includes a communication unit 10 for receiving a weather information signal for current weather information from a server 13, .

The communication unit 10 may be configured to include a GPS module that receives current position and weather information of the vehicle from satellites, This GPS module may have a configuration included in the AVN unit 30.

Meanwhile, in case that the vehicle is parked in an area where GPS reception is not possible, the communication unit 10 may be configured to be mediated by the mobile communication device 12 possessed by the driver. [0040] In this case, a smart phone can be applied to the terminal of the mobile communication device 12 at this time. Communication is performed between the AVN unit 30 and the mobile communication device terminal of the driver through the weather information related application installed in the smart phone, The information signal can be configured to be transmitted to the AVN unit 30. [

That is, when the weather information according to the embodiment of the present invention and the vehicle to which the vehicle HVAC control system associated with the AVN unit is applied are parked in a parking lot or a ground parking lot where GPS reception can be normally performed, weather information is provided through the GPS module A server 13 for providing weather information via a mobile communication device such as a smart phone possessed by the driver when the vehicle is parked in an underground parking lot where GPS reception is impossible, 13 to receive weather information signals and information on the vehicle.

When the vehicle to which the weather information according to the embodiment of the present invention and the vehicle HVAC control system associated with the AVN unit is started is started, the outside air temperature sensor and the inside air temperature sensor installed in the vehicle to prepare for driving the HVAC unit, The temperature is sensed. However, when the vehicle is parked in an indoor parking lot, especially when there is a great difference in temperature between the indoor parking lot and the outside, the temperature measured by the outdoor temperature sensor installed in the vehicle is not the temperature outside the parking lot, As the basic information for controlling the HVAC unit of the vehicle to be going out, distortions may occur if the temperature measured by the outside temperature sensor of the vehicle is directly applied to the outside temperature of the vehicle.

In the vehicle HVAC control system associated with the weather information and the AVN unit according to the embodiment of the present invention, the temperature value measured by the outdoor air temperature sensor of the vehicle and the weather information signal received by the AVN unit 30 If the difference is greater than or equal to the set value (preferably set in the range of 10 to 30 DEG C), it is determined that the vehicle is parked indoors, and the AVN unit 30 is controlled to drive the HVAC unit 40 And a controller 20 configured to reflect the temperature of the area where the vehicle is located among the received weather information signals.

The control unit 20 is connected to the AVN unit 30 of the vehicle through wired or wireless communication and provides the received weather information signal to the AVN unit 30 of the vehicle to generate AVN units 30, < / RTI > Also, the control unit 20 may be controlled through an ECU of the vehicle, and may be separately configured in the form of a modulated control unit.

As described above, the current location information of the car and the weather information of the current weather can be received through a medium such as the mobile communication device 12. At this time, the mobile communication device 12 and the AVN unit 30 ) Can receive signals through a Bluetooth or USB cable connection.

On the other hand, an application capable of communicating between the control unit 20 of the vehicle can be installed in a mobile communication device such as a smart phone. The smartphone and control unit interlocking application can be configured to be connected to the smartphone application providing server and downloaded and installed.

When the driver judges that the area where the vehicle is parked is in a place where GPS reception is impossible, the application of the smart phone is executed before starting the vehicle so that the current position information of the car and the weather information about the current weather AVN < / RTI > Therefore, weather information outside the parking lot is transmitted to the AVN unit 30 and the control unit 20, and the control unit 20 is configured to operate the HVAC unit 40 by reflecting temperature information outside the parking lot.

Of course, when the vehicle is not receiving GPS, the owner or the driver of the vehicle transmits the weather information signal from the server 13, which provides the weather information via his or her mobile communication device, The weather information signal received through the communication unit 10 may be transmitted to the AVN unit 30 mounted on the vehicle.

Accordingly, when the vehicle to which the weather information according to the embodiment of the present invention and the vehicle HVAC control system associated with the AVN unit are started is used, the temperature value measured by the outdoor air temperature sensor of the vehicle and the weather information received by the AVN unit 30 (For example, within a range of 10 to 30 degrees Celsius), it is determined that the vehicle has been parked in the room, and the HVAC unit (40) can be driven. On the other hand, when the difference between the temperature measured by the outside air temperature sensor in the state where the vehicle is started and the temperature information of the area where the vehicle is located among the weather information signals received by the AVN unit 30 is less than the set value, (40) can be driven.

Accordingly, when the car is parked in a ring or on the ground where GPS reception can normally be performed, the AVN unit 20 receives weather information on the current position and current weather of the vehicle through the GPS module, The AVN unit 20 receives weather information about the current location of the vehicle and the current weather via the mobile communication device 12 when the GPS is impossible to be received.

For example, when the temperature of the indoor parking lot where the vehicle is parked is 20 ° C and the temperature outside the parking lot is 10 ° C, it is expected that the vehicle will soon leave the parking lot, so that the operation of the air conditioner in the vehicle may be unnecessary , It is recognized that the external temperature value inputted from the outside air temperature sensor installed in the vehicle is 20 ° C, so that it is recognized that the outside air temperature is high and the air conditioner of the vehicle is operated. However, in the technology to which the present invention is applied, in the process of controlling the HVAC unit, the temperature of the area where the vehicle is parked, received from the server 13 that provides the weather information via the communication unit 10, It is possible to prevent power consumption of the vehicle because the air conditioner does not operate unnecessarily until the vehicle leaves the indoor parking lot.

As another example, if the temperature of the indoor parking lot is 10 ° C and the temperature outside the car park is 30 ° C, the temperature condition that the air conditioner needs to be started after a certain time (several tens of seconds to several minutes) do. Particularly, in a vehicle in which the operating condition of the HVAC unit is set to be automatically started when the outside temperature and / or the temperature in the car is higher than a certain temperature, the HVAC unit must be operated after the vehicle leaves the parking lot. However, according to the technology to which the present invention is applied, it is possible to predict the outside air temperature measured after several tens of seconds to several minutes in the process of controlling the HVAC unit, thereby maintaining favorable conditions for air conditioner driving. That is, in the process of controlling the HVAC unit by receiving the temperature information of the area where the vehicle is parked from the server 13 providing the weather information through the communication unit 10, in addition to the temperature of the indoor parking space measured by the outdoor air temperature sensor, The temperature is reflected to the external temperature. Therefore, according to the high temperature value measured by the outdoor air temperature sensor of the vehicle after leaving the indoor parking lot, the HVAC unit can be prevented from suddenly driving for air conditioner driving, and the thermal efficiency during the air conditioner driving process can be increased. In addition, it is possible to control the HVAC unit in a state in which the vehicle parked in the indoor parking lot meets the outside temperature during the time when the vehicle is outside.

On the other hand, when the indoor parking lot where the vehicle is parked is an area where GPS reception is impossible, communication between the AVN unit 30 can be performed by the driver's choice or automatically via the mobile communication device 12 such as a smart phone owned by the driver . In this way, even when the weather information or the like is provided via the mobile communication device 12 of the driver, the temperature in the indoor parking lot and the temperature information outside the parking lot can be used for controlling the HVAC unit, The driving environment of the vehicle driver can be more advantageous.

And items related to the weather information provided through the application installed in the GPS module or the mobile communication device 12 may be displayed on the monitor included in the AVN unit 30. [

It is expected that the HVAC control system of an automobile in which the weather information and the AVN unit are connected according to the present invention can be used efficiently in electric vehicles.

In particular, in the case of an electric vehicle, efficient use of electric power is very important in the process of using electricity charged in the battery. In the conventional case, the HAVC is automatically or manually operated There is a problem in that the power use is inefficient, but such a problem can be solved when the present invention is applied.

Hereinafter, a method of controlling the HVAC of the vehicle using the HVAC control system of the vehicle in which the weather information of the present invention configured as described above is connected to the AVN unit will be described.

FIG. 2 is a flowchart showing a procedure of a vehicle HVAC control method using the weather information of the present invention and the vehicle HVAC control system associated with the AVN.

Referring to FIG. 2, the method of controlling a vehicle HVAC using the weather information and the vehicle HVAC control system associated with the AVN according to the present invention first receives information on the current weather from the server 13, which stores weather information, (S10).

Thereafter, the control unit 20 transmits the weather information received through the communication unit 10 to the AVN unit (S20) and the weather information received by the AVN unit to the control unit 20 (S30) In order to be able to reflect not only the outside temperature of the vehicle measured by the outside air temperature sensor but also the temperature information outside the car park provided through the communication unit 10 in the process of controlling the HVAC unit of the vehicle, Outside temperature information is provided.

Thereafter, the temperature value measured by the outside air temperature sensor of the vehicle is compared with the temperature value of the area where the vehicle is located in the weather information signal received by the AVN unit (S40).

If the temperature value measured by the outside air temperature sensor of the vehicle and the temperature value of the parked area received by the AVN unit are equal to or greater than the preset value, (S50). ≪ / RTI >

If it is determined in the previous temperature comparison step that the vehicle has been parked indoors, the control unit 10 controls the HVAC unit (S60) by reflecting the temperature value of the area where the vehicle is located in the weather information signal received through the communication unit 10 do.

On the other hand, when the GPS module mounted on the AVN unit operates normally in the step of receiving the weather information signal through the communication unit, the current position and weather information of the vehicle are received through the GPS module.

If the GPS module is not operating normally, the current location and weather information of the vehicle may be received via the mobile communication device (smart phone, etc.) owned by the vehicle driver through the Bluetooth module installed in the AVN unit.

As described above, in particular, when the vehicle is parked in the vehicle, the vehicle is started in the process of controlling the HVAC unit, and at the same time the temperature value of the parked area as well as the temperature value measured by the outdoor air temperature sensor may be reflected So that it becomes possible to more efficiently use the electric power according to the driving of the HVAC unit.
