본 발명은 차량용 공조시스템의 제어장치에 관한 것으로서, 보다 상세하게는, 일사센서 없이도 시스템의 제어에 필요한 일사부하 데이터를 얻을 수 있는 차량용 공조시스템의 제어장치에 관한 것이다.The present invention relates to a control device for a vehicle air conditioning system, and more particularly, to a control device for a vehicle air conditioning system that can obtain the solar load data required for the control of the system without the solar sensor.

최근 들어, 차량용 공조시스템은 자동제어방식으로 개선되고 있다.Recently, the vehicle air conditioning system has been improved by an automatic control method.

자동제어방식 공조시스템은, 차량의 외기 온도와 습도, 차량의 내기 온도와 습도, 일사부하 등을 감지한 다음, 감지된 각각의 데이터에 따라 차량의 실내온도와 습도를 자동으로 조절한다. 따라서, 차량의 실내 온도와 습도를 항상 쾌적하게 유지시킨다.The automatic control air conditioning system detects the vehicle's outdoor air temperature and humidity, the vehicle's air temperature and humidity, and solar load, and then automatically adjusts the indoor temperature and humidity of the vehicle according to the detected data. Therefore, the room temperature and humidity of the vehicle are always kept comfortable.

한편, 이러한 자동제어방식 공조시스템(이하, "공조시스템"이라 약칭함)은, 시스템을 제어하기 위한 제어장치를 갖추고 있다.On the other hand, such an automatic control system air conditioning system (hereinafter, abbreviated as "air conditioning system") has a control device for controlling the system.

제어장치는, 차량의 실내온도를 감지하기 위한 실내온도센서(In-Car Sensor)와, 차량의 외기온도를 감지하기 위한 외기센서와, 일사부하를 감지하는 일사센서와, 이들 각각의 센서로부터 입력된 데이터를 처리하는 콘트롤러(Controller)를 구 비한다.The control device includes an in-car sensor for sensing the indoor temperature of the vehicle, an outside air sensor for sensing the outside temperature of the vehicle, a solar sensor for sensing the solar load, and inputs from each of these sensors. It has a controller that processes the data.

특히, 콘트롤러는, 각각의 센서로부터 입력된 데이터를 처리하여 각종 도어와 블로어와 압축기 및 보조히터 등을 제어한다. 따라서, 차량의 실내온도와 습도를 외기온도와 습도에 맞춰서 항상 쾌적하게 유지시킨다.In particular, the controller processes data input from each sensor to control various doors, blowers, compressors, auxiliary heaters, and the like. Therefore, the indoor temperature and humidity of the vehicle are always kept comfortable in accordance with the outdoor temperature and humidity.

그런데, 이러한 종래의 제어장치는, 일사센서가 일사부하를 정확하게 감지할 수 없는 경우가 발생한다는 단점이 있다.However, such a conventional control apparatus has a disadvantage in that a case in which the solar sensor cannot detect the solar load accurately occurs.

예를 들면, 태양이 일시적으로 구름에 가렸을 경우나, 차량이 터널에 진입하였을 경우에는, 태양빛이 일시적으로 차단된다. 이럴 때, 차량은 일사에 의한 열적부하가 많은 상태이지만 일사센서의 입력이 없어 일사보상을 하지 않아 실내가 쾌적하게 제어되지 않는다.For example, when the sun is temporarily obscured by clouds or when a vehicle enters a tunnel, sunlight is temporarily blocked. In this case, the vehicle is in a state of high thermal load due to the solar radiation, but the solar sensor is not input because the solar sensor is not compensated for the interior is not comfortably controlled.

결과적으로, 일사에 의한 차량 열적 부하 상태를 감지할 수 없으므로, 일사부하에 따라 공조시스템을 정밀하게 제어할 수 없다는 문제점이 있으며, 이러한 문제점 때문에 차량의 실내 온도와 습도를 쾌적하게 유지시킬 수 없다는 결점이 있다.As a result, there is a problem that the air conditioning system cannot be precisely controlled according to the solar load because it is impossible to detect the vehicle thermal load due to the solar radiation. There is this.

또한, 위와 같은 종래의 기술은, 별도의 일사센서가 필요하고, 이를 작동시키기 위한 별도의 부품이나 프로그램이 요구되므로, 많은 비용이 소요된다는 단점이 있으며, 이러한 단점 때문에 제조원가가 상승된다는 문제점도 있다.In addition, the prior art as described above, because a separate solar sensor is required, and a separate part or program for operating the same, there is a disadvantage that takes a lot of cost, there is also a problem that the manufacturing cost is increased due to this disadvantage.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서, 그 목적은, 실제의 일사부하에 관계없이 태양빛이 일시적으로 차단될 경우라도, 시스템의 제어에 필요한 일사부하를 정확하게 감지할 수 있는 차량용 공조시스템의 제어장치를 제공하는 데 있다.The present invention has been made to solve the above-mentioned conventional problems, the object of which is to accurately detect the solar load required for the control of the system, even if the sunlight is temporarily blocked irrespective of the actual solar load. It is to provide a control device for a vehicle air conditioning system.

본 발명의 다른 목적은, 시스템의 제어에 필요한 일사부하를 정확하게 감지함으로써, 공조시스템을 정밀하게 제어할 수 있고, 따라서, 차량의 실내 온도를 항상 쾌적하게 유지시킬 수 있는 차량용 공조시스템의 제어장치를 제공하는 데 있다.Another object of the present invention is to accurately control the solar load required for the control of the system, so that the air conditioning system can be precisely controlled, and therefore, a control device for a vehicle air conditioning system that can always maintain the room temperature of the vehicle comfortably. To provide.

본 발명의 또 다른 목적은, 일사센서 없이도 차량 루프에 실내온도센서를 장착해서 시스템의 제어에 필요한 일사부하를 정확하게 감지할 수 있음으로써, 부품의 수를 절감할 수 있고, 따라서, 제조원가를 저감시킬 수 있는 차량용 공조시스템의 제어장치를 제공하는 데 있다.It is still another object of the present invention to mount a room temperature sensor on a vehicle roof without a solar sensor so that the solar load required for the control of the system can be accurately sensed, thereby reducing the number of parts and thus reducing the manufacturing cost. To provide a control device for a vehicle air conditioning system that can be.

이러한 목적을 달성하기 위하여 본 발명의 차량용 공조시스템의 제어장치는, 차량의 실내온도를 감지하는 실내온도센서와, 상기 실내온도센서로부터 입력된 데이터를 처리하여 공조시스템을 제어하는 콘트롤러를 포함하는 차량용 공조시스템의 제어장치에 있어서, 상기 실내온도센서는, 차량의 실내 공기온도를 감지함과 동시에 태양의 일사부하를 감지할 수 있도록 실내온도와 태양의 일사부하, 양쪽 모두가 전달되는 루프측에 설치되고, 상기 콘트롤러는, 실내온도와 일사부하가 반영된 상기 실내온도센서의 감지온도를 처리하여 상기 공조시스템을 제어하는 것을 특징으로 한다.In order to achieve the above object, a control apparatus of a vehicle air conditioning system of the present invention includes a room temperature sensor for detecting a room temperature of a vehicle, and a controller for controlling an air conditioning system by processing data input from the room temperature sensor. In the control system of the air conditioning system, the indoor temperature sensor is installed on the roof side where both the indoor temperature and the solar solar load are transmitted so as to sense the indoor air temperature of the vehicle and the solar solar load. The controller may control the air conditioning system by processing a sensed temperature of the indoor temperature sensor in which room temperature and solar radiation are reflected.

바람직하게는, 상기 실내온도센서는, 차량의 실내온도와 상기 루프에 조사된 태양의 일사부하가 전달되는 루프패널과 루프라이닝 사이의 내부공간에 설치되는 것을 특징으로 한다.Preferably, the indoor temperature sensor is characterized in that it is installed in the interior space between the roof panel and the roof lining to which the vehicle's room temperature and the solar load irradiated to the roof are transmitted.

그리고 상기 루프패널로부터 상기 실내온도센서로의 열전도율이 증가될 수 있도록 상기 루프패널과 상기 실내온도센서의 사이에 열전달부재를 더 포함하는 것을 특징으로 한다.And a heat transfer member between the roof panel and the room temperature sensor to increase the thermal conductivity from the roof panel to the room temperature sensor.

본 발명에 따른 차량용 공조시스템의 제어장치에 의하면, 실내온도센서를 루프측에 설치하는 구조이므로, 실내온도센서로써 루프 내측의 실내온도와 루프 외측의 일사부하를 동시에 감지할 수 있는 효과가 있다.According to the control device of the vehicle air conditioning system according to the present invention, since the indoor temperature sensor is installed on the roof side, the indoor temperature sensor can simultaneously detect the indoor temperature inside the roof and the solar load outside the roof.

또한, 실내온도센서를 루프측에 설치하는 구조이므로, 태양의 일시적인 차단 현상에도 불구하고 일정한 온도를 유지하는 루프의 일사부하를 감지할 수 있으며, 따라서, 실제의 일사부하에 관계없이 태양의 일사부하가 일시적으로 차단될 경우라도, 시스템의 제어에 필요한 일사부하를 정확하게 감지할 수 있는 효과가 있다.In addition, since the indoor temperature sensor is installed on the roof side, it is possible to detect the solar radiation load of the loop which maintains a constant temperature despite the temporary interruption of the sun, and thus the solar solar load regardless of the actual solar load. Even if is temporarily blocked, there is an effect that can accurately detect the solar load required for the control of the system.

또한, 루프에 설치된 실내온도센서를 통해 실내온도와 일사부하 모두를 감지하는 구조이므로, 별도의 일사센서 없이도 시스템의 제어에 필요한 일사부하를 정확하게 감지할 수 있는 효과가 있다.In addition, since the indoor temperature sensor installed in the roof structure to detect both the indoor temperature and the solar load, there is an effect that can accurately detect the solar load required for the control of the system without a separate solar sensor.

또한, 별도의 일사센서가 필요없으므로, 부품수를 절감할 수 있으며, 부품수를 절감할 수 있으므로, 비용절감의 효과를 기대할 수 있다.In addition, since there is no need for a separate solar sensor, it is possible to reduce the number of parts, it is possible to reduce the number of parts, it can be expected to reduce the cost effect.

또한, 비용절감이 요구되는 저가형 차량들에 채용될 경우, 부품수를 절감할 수 있으므로, 저가형 차량들의 가격 경쟁력을 향상시킬 수 있는 효과가 있다.In addition, when it is employed in low-cost vehicles that require cost reduction, it is possible to reduce the number of parts, there is an effect that can improve the price competitiveness of low-priced vehicles.

이하, 본 발명에 따른 차량용 공조시스템의 제어장치의 바람직한 실시예를 첨부한 도면에 의거하여 상세히 설명한다(종래와 동일한 구성요소는 동일한 부호를 사용하여 설명한다).Best Mode for Carrying Out the Invention Preferred embodiments of a control apparatus for a vehicle air conditioning system according to the present invention will be described in detail with reference to the accompanying drawings (the same components will be described using the same reference numerals).

먼저, 본 발명에 따른 제어장치의 특징부를 살펴보기에 앞서, 도 1을 참조하여 차량용 공조시스템의 제어장치에 대해 간략하게 살펴본다.First, before looking at the features of the control device according to the present invention, a brief description of the control device of the vehicle air conditioning system with reference to FIG.

제어장치는, 실내온도센서(1)와 외기센서(3)를 구비한다. 실내온도센서(1)는 온도감지센서로서, 차량의 실내온도를 감지하여 후술하는 콘트롤러(5)에 입력시킨다. 외기센서(3)는 차량의 외기온도를 감지하여 콘트롤러(5)에 입력시킨다.The control device includes an indoor temperature sensor 1 and an outside air sensor 3. The indoor temperature sensor 1 is a temperature sensor and detects the indoor temperature of the vehicle and inputs it to the controller 5 to be described later. The outside air sensor 3 detects the outside air temperature of the vehicle and inputs it to the controller 5.

콘트롤러(5)는, 마이크로 프로세서와 구동회로를 내장하고 있는 것으로, 실내온도센서(1)와 외기센서(3)로부터 입력된 데이터를 처리하여 각종 도어(7, 8, 9)들과 블로어(10)와 압축기(12) 및 보조히터(14)등을 제어한다.The controller 5 incorporates a microprocessor and a driving circuit. The controller 5 processes data input from the indoor temperature sensor 1 and the outside air sensor 3 to control various doors 7, 8, 9 and blower 10. ), The compressor 12 and the auxiliary heater 14 and the like.

다음으로, 본 발명에 따른 제어장치의 특징부를 도 1 내지 도 3을 참조하여 상세하게 살펴본다.Next, the features of the control device according to the present invention will be described in detail with reference to FIGS. 1 to 3.

먼저, 본 발명의 제어장치는, 실내온도센서(1)를 구비하되, 상기 실내온도센서(1)는 도 2에 도시된 바와 같이, 차량의 루프(Roof)(20)에 설치된다. 특히, 태양의 일사부하가 직접적으로 작용하는 루프(20)에 설치된다. 따라서, 루프(20)에 작용하는 일사부하를 감지하도록 구성된다.First, the control device of the present invention includes an indoor temperature sensor 1, the indoor temperature sensor 1 is installed in the roof (Roof) 20 of the vehicle, as shown in FIG. In particular, the solar radiation load is installed in the loop 20 directly acting. Thus, it is configured to detect the solar load acting on the loop 20.

이를 상세하게 살펴보면, 실내온도센서(1)는, 도 3에 도시된 바와 같이, 루프(20)를 구성하는 루프패널(Roof Panel)(22)의 내측면에 설치된다. 특히, 루프패 널(22)과 루프라이닝(Roof Lining)(24)사이의 내부공간부분에 설치된다.Looking at this in detail, the room temperature sensor 1, as shown in Figure 3, is installed on the inner surface of the roof panel (Roof Panel) 22 constituting the loop (20). In particular, it is installed in the inner space portion between the roof panel 22 and the roof lining (Roof Lining) 24.

이러한 실내온도센서(1)는, 루프패널(22)과 루프라이닝(24)사이에 설치되므로, 차량의 실내온도와, 루프패널(22)로부터 전달되는 일사부하의 전도열, 양쪽 모두로부터 영향받는다.Since the indoor temperature sensor 1 is provided between the roof panel 22 and the roof lining 24, both the indoor temperature of the vehicle and the conductive heat of the solar load transmitted from the roof panel 22 are affected.

따라서, 차량의 실내온도를 감지함과 동시에 루프패널(22)로부터 전도되는 일사부하를 동시에 감지하며, 이에 따라, 실내온도와 일사부하 모두를 동시에 감지하는 역할을 한다.Therefore, the indoor temperature of the vehicle is sensed at the same time and the solar load conducted from the roof panel 22 at the same time, thereby detecting both the indoor temperature and the solar load at the same time.

이러한 구성의 실내온도센서(1)는, 실내온도와 일사부하 모두를 감지하므로, 별도의 일사센서 없이도 "일사부하 데이터"를 얻을 수 있다. 그리고 얻어진 "일사부하 데이터"를 콘트롤러(5)에 제공함으로써, 콘트롤러(5)로 하여금 "일사부하 데이터"를 감안하여 공조시스템을 정밀하게 제어할 수 있도록 한다.Since the indoor temperature sensor 1 of this configuration detects both the indoor temperature and the solar load, it is possible to obtain "sun load data" without a separate solar sensor. Then, by providing the obtained " solar load data " to the controller 5, the controller 5 can accurately control the air conditioning system in consideration of the " solar load data ".

또한, 실내온도센서(1)는, 루프(20)에 설치되므로, 태양의 일시적인 차단 현상에도 불구하고 일정한 온도를 유지하는 루프(20)의 일사부하를 감지할 수 있다. 따라서, 실제의 일사부하에 관계없이 태양의 일사량이 일시적으로 차단될 경우라도, 시스템의 제어에 필요한 일사부하를 정확하게 감지할 수 있다.In addition, since the indoor temperature sensor 1 is installed in the roof 20, the solar load of the loop 20 that maintains a constant temperature despite a temporary blocking phenomenon of the sun may be detected. Therefore, even when the solar radiation amount is temporarily interrupted regardless of the actual solar load, it is possible to accurately detect the solar load necessary for controlling the system.

또한, 실내온도센서(1)는, 루프(20)에 설치되므로, 실내의 최상측 온도를 감지할 수 있고, 실내의 최상측 온도를 감지할 수 있음에 따라 실내의 최상측 온도를 근거로 하여 공조시스템을 제어할 수 있게 한다.In addition, since the indoor temperature sensor 1 is installed in the roof 20, the indoor temperature sensor 1 can detect the top temperature of the room, and can detect the top temperature of the room based on the top temperature of the room. Allows you to control the air conditioning system.

특히, 일사부하에 따라 가장 민감하게 반응하는 실내의 최상측 온도를 감지하고, 이를 근거로 공조시스템을 제어할 수 있도록 함으로써, 일사 보상의 효과가 나타날 수 있게 한다.In particular, by detecting the top temperature of the room that reacts most sensitively to the solar load, and by controlling the air conditioning system based on this, the effect of solar compensation can be shown.

다시, 도 3을 참조하면, 본 발명의 제어장치는, 루프패널(22)에 조사된 일사부하를 실내온도센서(1)에 전달하는 열전달부재(30)를 더 구비한다.Referring again to FIG. 3, the control device of the present invention further includes a heat transfer member 30 for transmitting the solar load irradiated to the roof panel 22 to the room temperature sensor 1.

열전달부재(30)는, 열전달율이 높은 재질, 예를 들면, 금속재질로 구성되며, 루프패널(22)의 상면에 조사된 일사부하를 실내온도센서(1)에 전달하는 역할을 한다.The heat transfer member 30 is made of a material having a high heat transfer rate, for example, a metal material, and serves to transmit the solar load irradiated on the upper surface of the roof panel 22 to the room temperature sensor 1.

이러한 열전달부재(30)는, 루프패널(22)에 조사된 일사부하를 실내온도센서(1)에 전달하므로, 루프패널(22)로부터 실내온도센서(1)로 전달되는 일사부하의 열전도효율을 증가시켜준다.Since the heat transfer member 30 transmits the solar load irradiated to the roof panel 22 to the room temperature sensor 1, the heat transfer efficiency of the solar load transmitted from the roof panel 22 to the room temperature sensor 1 is increased. Increase.

따라서, 실내온도센서(1)의 일사부하 감지효율을 극대화시키고, 일사부하 감지효율을 극대화시킴으로써, 실제 태양의 일사부하와 근접한 일사부하를 감지할 수 있게 하며, 태양의 일사부하와 근접한 일사부하를 감지할 수 있게 함으로써, 이를 근거로 공조시스템을 정밀하게 제어할 수 있게 한다.Accordingly, by maximizing the solar load detection efficiency of the indoor temperature sensor 1 and maximizing the solar load detection efficiency, it is possible to detect the solar load close to the actual solar load and the solar load close to the solar load of the sun. By allowing detection, it is possible to precisely control the air conditioning system based on this.

그리고 본 발명의 제어장치는, 실내온도센서(1)에 대응하는 루프라이닝(24)에 통기용 그릴(24a)이 설치되는 구성을 갖는다. 통기용 그릴(24a)은 차실내의 공기가 통과하여 실내온도센서(1)와 접촉할 수 있게 하며, 따라서, 차실내 공기의 온도가 실내온도센서(1)에 보다 효율좋게 반영될 수 있게 한다.And the control apparatus of this invention has the structure which the ventilation grille 24a is provided in the roof lining 24 corresponding to the room temperature sensor 1. As shown in FIG. The ventilation grille 24a allows the air in the cabin to pass through and makes contact with the room temperature sensor 1, thus allowing the temperature of the cabin air to be more efficiently reflected to the room temperature sensor 1. .

한편, 도 4에는 본 발명의 다른 실시예가 도시되어 있다. 다른 실시예의 본 발명은, 실내온도센서(1)가 열전달부재(30)없이 루프패널(22)과 루프라이닝(24)사이의 내부공간부분에 직접 설치되는 구성이다.On the other hand, Figure 4 shows another embodiment of the present invention. In another embodiment of the present invention, the indoor temperature sensor 1 is directly installed in the inner space portion between the roof panel 22 and the roof lining 24 without the heat transfer member 30.

이러한 다른 실시예의 실내온도센서(1)는, 루프패널(22)측 일사부하에 의해 가열된 내부공간의 공기온도가 작용한다. 따라서, 차량의 실내온도와, 루프패널(22)로부터 전달되는 일사부하, 양쪽 모두로부터 영향받고 이들 모두를 동시에 감지한다.In the indoor temperature sensor 1 of this other embodiment, the air temperature of the internal space heated by the solar panel load on the roof panel 22 side acts. Therefore, both the indoor temperature of the vehicle and the solar load transmitted from the roof panel 22 are affected and both are simultaneously sensed.

한편, 본 발명자는, 이러한 구성을 갖는 본 발명의 성능을 알아보기 위해, 루프에 설치된 본 발명의 실내온도센서와, 운전석 전방의 콘트롤패널과 인스트루먼트 패널에 각각 설치된 종래의 실내온도센서의 온도감지효율을 비교 시험해 보았다.On the other hand, the present inventors, in order to find out the performance of the present invention having such a configuration, the temperature sensing efficiency of the room temperature sensor of the present invention installed in the roof, and the conventional room temperature sensor respectively installed in the control panel and the instrument panel in front of the driver's seat Compared and tried.

시험결과, 도 5에 도시된 바와 같이, 루프에 설치된 본 발명의 실내온도센서는, 콘트롤패널과 인스트루먼트 패널에 설치된 종래의 실내온도센서들보다 감지 온도가 훨씬 더 높은 것으로 나타났다. 따라서, 루프에 설치된 본 발명의 실내온도센서는, 실내온도에 영향받음은 물론 루프에 작용하는 일사부하에도 영향 받음을 알 수 있다.As a result of the test, as shown in Figure 5, the room temperature sensor of the present invention installed in the roof, the sensing temperature is much higher than the conventional room temperature sensors installed in the control panel and the instrument panel. Therefore, it can be seen that the indoor temperature sensor of the present invention installed in the roof is affected not only by the indoor temperature but also by the solar load acting on the loop.

또한, 루프에 설치된 본 발명의 실내온도센서는, 시간이 지남에 따라 일사 부하가 증가되는 것으로 나타났다. 특히, 일사부하가 0Ｗ∼1200Ｗ 까지 변경됨을 알 수 있다. 따라서, 루프에 설치된 본 발명의 실내온도센서는, 루프에 작용하는 일사로 인해 많은 일사부하를 받는 것을 알 수 있다.In addition, the room temperature sensor of the present invention installed in the loop, it was found that the solar load is increased over time. In particular, it can be seen that the solar load is changed from 0Ｗ to 1200Ｗ. Therefore, it can be seen that the room temperature sensor of the present invention installed in the loop receives a lot of solar load due to the solar radiation acting on the loop.

결과적으로, 본 발명의 실내온도센서(1)는, 실내온도와 일사부하, 양쪽 모두로부터 동시에 영향받으므로, 실내온도와 일사부하를 동시에 감지하는 것을 알 수 있으며, 이렇게 감지된 온도는 실내온도와 일사부하가 감안된 온도임을 알 수 있 다.As a result, since the indoor temperature sensor 1 of the present invention is simultaneously affected by both the indoor temperature and the solar load, it can be seen that the indoor temperature and the solar load are simultaneously sensed. It can be seen that the solar load is considered.

따라서, 본 발명의 실내온도센서(1)는, 별도의 일사센서 없이도 태양의 일사부하를 감지할 수 있고, 이에 따라, 별도의 일사센서 없이도 일사부하에 의한 온도제어 등이 가능하도록 하는 효과가 있다.Therefore, the indoor temperature sensor 1 of the present invention can detect the solar load of the sun without a separate solar sensor, thereby, it is possible to control the temperature by the solar load without a separate solar sensor. .
