본 발명은 겨울철 등에 차량의 시동 초기에 외부에서 유입된 찬 공기가 발 부분으로 토출되지 않게 하는 차량의 시동시 난방 제어방법에 관한 것으로서, 특히 PTC 히터가 구비된 차량에서 PTC 히터에 의한 난방 성능을 향상시킬 수 있는 차량의 시동시 난방 제어방법에 관한 것이다. The present invention relates to a heating control method at start-up of a vehicle to prevent the cold air introduced from the outside during the start of the vehicle in the winter, such as to discharge to the feet, particularly the heating performance by the PTC heater in a vehicle equipped with a PTC heater A heating control method at start-up of a vehicle that can be improved.
종래의 차량의 시동시 난방 제어방법은 도 1에 도시된 바와 같이, 차량이 시동된 후 난방모드로 공조장치를 작동시키면 난방기동제어 진입조건에 해당되는지를 확인하는 단계와; 난방기동제어 진입조건에 해당되면 난방기동제어 해제조건을 만족할 때까지 난방기동제어를 실시하는 단계와; 난방기동제어 해제조건을 만족하면 난방기동제어를 중지하고 자동제어를 실시하는 단계로 구성되어 있다.As shown in FIG. 1, a heating control method when starting a vehicle includes checking whether a heating start control entry condition corresponds to operating the air conditioner in a heating mode after the vehicle is started; Performing heating start control until the heating start control releasing condition is satisfied when the heating start control entry condition is satisfied; When the heating start control release condition is satisfied, the heating start control is stopped and the automatic control is performed.
여기서, 상기 난방기동제어 진입조건이란 공조장치를 자동제어모드로 제어시 플로어 토출모드인 상태에서 외기온이 10℃ 이하이고, 냉각수온이 73℃ 이하인 조건을 모두 만족하는 것을 말한다. 물론, 상기 난방기동제어 해제조건은 상기한 난방기동제어 진입조건을 벗어나는 것을 의미하며, 대부분 냉각수온이 73℃를 초과하면 난방기동제어를 중지하게 된다.Here, the heating start control entry condition means that the outside air temperature is 10 ° C. or less and the cooling water temperature is 73 ° C. or less when the air conditioner is controlled in the automatic control mode. Of course, the condition for releasing the heating start control means that the heating start control entry condition is deviated. When the cooling water temperature exceeds 73 ° C., the heating start control is stopped.
여기서, 난방기동제어는 시동 초기에 외부에서 유입되는 찬공기가 발 부분으로 토출되지 않도록 토출 방향을 조정하고 풍량을 서서히 증대시키는 제어 로직으로, 도 2에 도시된 그래프처럼 나타낼 수 있다. 즉, 난방기동제어는 시동 초기에는 디프로스트 토출모드(DEF)로 한 상태에서 블로워의 전압을 로우(LOW), 즉 블로워의 단수를 최하단으로 유지하다가 엔진 냉각수의 온도가 일정 온도에 이르면, 혼합 토출모드(MIX)로 설정하고 블로워의 전압을 점차 상승시켜 감으로써 서서히 난방을 시작하게 된다. 여기서, 혼합 토출모드(MIX)라 함은, 상측의 디프로스트(defrost) 토출구는 물론 하측의 풋(Foot) 토출구로도 공기가 토출되는 모드이다.Here, the heating start control is a control logic that adjusts the discharge direction and gradually increases the amount of air so that cold air introduced from the outside at the initial stage of startup is not discharged to the foot, and may be represented as a graph shown in FIG. 2. That is, the heating start control maintains the blower voltage low in the defrost discharge mode (DEF) at the beginning of the start, that is, the stage of the blower is kept at the lowest level, and then the mixed discharge is performed when the temperature of the engine coolant reaches a certain temperature. The mode (MIX) is set and heating is gradually started by gradually increasing the blower voltage. Here, the mixed discharge mode MIX is a mode in which air is discharged not only to the upper defrost discharge port but also to the lower foot discharge port.
물론, 냉각수의 온도가 난방기동제어의 해제조건에 해당되면 난방기동제어를 중지하고 자동제어를 실시하는데, 자동제어를 실시하는 초기에는 불로워 전압을 상승시키지만 하이(HIGH), 즉 블로워의 단수를 최고단까지는 상승시키지 않고 일정한 전압으로 유지하고 있다. 다시 말해서, 난방기동제어는 엔진 냉각수의 온도가 설정 온도에 이를 때까지만 시행되며, 그 뒤에는 자동제어를 실시하게 된다.Of course, when the temperature of the coolant falls under the condition of releasing the heating start control, the heating start control is stopped and the automatic control is performed.In the initial stage of the automatic control, the blower increases the voltage, but the high stage, the blower It is kept at a constant voltage without raising to the highest end. In other words, heating start control is executed only until the temperature of the engine coolant reaches a set temperature, and then automatic control is performed.
여기서, 자동제어란 FATC(Full Automatic Temperature Control)제어를 의미 하며, 환경 정도에 따라 자동으로 온도나 블로워의 풍량 및 풍향 등이 정해지는 제어를 의미한다.Here, automatic control means full automatic temperature control (FAT) control, and means a control in which a temperature, a blower's air volume, and a wind direction are automatically determined according to the environment.
상기한 종래의 차량의 시동시 난방 제어방법은 차량의 환경조건이 난방기동제어의 진입조건에 해당되면 난방기동제어를 실시하고 난방기동제어의 해제조건에 해당되면 난방기동제어를 중지하고 자동제어를 실시하도록 하고 있다.The heating control method at the start of the conventional vehicle starts heating control when the environmental condition of the vehicle corresponds to the entry condition of the heating start control, and stops the heating start control and automatically controls the control when the release condition of the heating start control is met. We are going to do it.
차량이 시동된 후 난방모드로 공조장치를 작동시키면 난방기동제어 진입조건에 해당되는지를 확인한다. 이때, 난방기동제어 진입조건에 해당되면 난방기동제어를 실시하고 그렇지 않으면 자동제어를 실시한다. 난방기동제어를 실시하면 송풍량이 최소로 유지되어 냉각수의 온도가 빠르게 상승하게 되므로, 제어부는 상승되고 있는 냉각수의 온도가 난방기동제어 해제조건을 만족하는지를 확인한다. 냉각수의 온도가 난방기동제어 해제조건을 만족하면 난방기동제어를 중지하고 자동제어를 실시하게 된다.If the air conditioner is operated in the heating mode after the vehicle is started, check whether the heating start control entry condition is met. At this time, if the heating start control entry condition is met, heating start control is performed, otherwise automatic control is performed. When the heating start control is performed, the air volume is kept to a minimum, and thus the temperature of the cooling water rises rapidly. The controller checks whether the temperature of the rising cooling water satisfies the heating start control releasing condition. When the temperature of the coolant satisfies the condition for releasing the heating start control, the heating start control is stopped and automatic control is performed.
그러나, 상기한 종래의 차량의 시동시 난방 제어방법은 PTC 히터가 채용된 차량에서는 초기 시동시 PTC 히터에 의해 더운 공기가 유입됨에도 불구하고 냉각수온만을 기준으로 하여 공조장치를 제어하게 되므로 실제 난방시점이 늦어지고 PTC 히터에 의한 난방성능이 저하되도록 하는 문제점이 있다.However, the heating control method at the start of the conventional vehicle, in the vehicle employing the PTC heater, in spite of the hot air is introduced by the PTC heater during the initial start-up, the air conditioner is controlled only on the basis of the cooling water temperature. There is a problem that the delay and the heating performance by the PTC heater is lowered.
즉, PTC 히터가 채용된 차량의 경우 차량 시동과 동시에 PTC 히터가 작동되어 더운 공기가 발생되지만, 냉각수온에 의해서만 난방기동제어가 해제되도록 되어 있어 실내 온도가 느리게 상승하게 된다. 이는 PTC 히터의 효과를 제대로 활용하지 못하는 것을 의미하며, PTC 히터의 난방성능을 저하시키는 요인이 된다. That is, in the case of a vehicle employing a PTC heater, the PTC heater is operated at the same time as the vehicle is started, and hot air is generated, but the heating start control is released only by the coolant temperature, so that the room temperature rises slowly. This means that the effect of the PTC heater is not properly utilized, which causes deterioration in the heating performance of the PTC heater.
본 발명은 상기한 종래 문제점을 해결하기 위하여 안출된 것으로서, PTC 히터가 채용된 차량에서는 난방기동제어 진입조건에 해당될 때 PTC 히터의 작동 여부에 따라 난방기동제어의 실시 여부를 결정하도록 함으로써 조기 난방이 가능해지며 PTC 히터의 난방성능을 최대로 활용할 수 있도록 하는 차량의 시동시 난방 제어방법을 제공하는데 그 목적이 있다.The present invention has been made to solve the above-mentioned conventional problems, and in a vehicle employing a PTC heater, when the heating start control entry conditions are met, it is determined that the heating start control is executed according to the operation of the PTC heater. The purpose of the present invention is to provide a heating control method at the start of a vehicle, which enables to maximize the heating performance of the PTC heater.
또, 본 발명은 난방기동제어의 진입조건 및 해제조건을 특정하여 난방기동제어가 제한적으로만 이루어지도록 함으로써 PTC 히터의 활용도를 최대화할 수 있는 차량의 시동시 난방 제어방법을 제공하는데 다른 목적이 있다.In addition, another object of the present invention is to provide a heating control method at start-up of a vehicle which can maximize the utilization of the PTC heater by specifying the entry and release conditions of the heating start control so that the heating start control is limited. .
또한, 본 발명은 시동 초기에 PTC 히터가 작동될 때 공조모드를 특정함으로써 빠른 시간 내에 실내 난방이 가능하도록 하는 차량의 시동시 난방 제어방법을 제공하는데 그 목적이 있다.In addition, an object of the present invention is to provide a heating control method at start-up of a vehicle which enables indoor heating within a short time by specifying an air conditioning mode when the PTC heater is operated at the initial stage of starting.
상기한 목적을 달성하기 위한 본 발명의 차량의 시동시 난방 제어방법에 따르면, 차량이 시동된 후 난방모드로 공조장치를 작동시키면 난방기동제어 진입조건에 해당되는지를 확인하는 단계와; 난방기동제어 진입조건에 해당되면 PTC 히터가 작동중인지를 확인하고 그렇지 않으면 자동제어를 실시하는 단계와; PTC 히터가 작동중이면 일정 시간 동안 특정제어를 실시한 후 자동제어를 실시하고 그렇지 않으면 난방기동제어 해제조건을 만족할 때까지 난방기동제어를 실시하는 단계와; 난방기동제어 해제조건을 만족하면 난방기동제어를 중지하고 자동제어를 실시하는 단계 를 포함한다.According to the heating control method at the start of the vehicle of the present invention for achieving the above object, if the air conditioner is operated in the heating mode after the vehicle is started, confirming whether the heating start control entry condition; Checking whether the PTC heater is in operation when the heating start control entry condition is met; otherwise, performing automatic control; Performing specific control for a predetermined time if the PTC heater is in operation, then performing automatic control, and otherwise heating heating control until the heating start control releasing condition is satisfied; And stopping the heating start control and performing automatic control when the heating start control release condition is satisfied.
또, 본 발명의 차량의 시동시 난방 제어방법에 따르면, 상기 난방기동제어 진입조건은 공조장치를 자동제어모드로 제어시 플로어 토출모드인 상태에서 외기온이 10℃ 이하, 냉각수온이 73℃ 이하일 때이다.Further, according to the heating control method when starting the vehicle of the present invention, the heating start control entry condition is when the outside air temperature is 10 ℃ or less, the cooling water temperature is 73 ℃ or less in the state of the floor discharge mode when the air conditioner is controlled in the automatic control mode to be.

상기한 본 발명의 특징 및 이점들은 첨부도면에 의거한 다음의 상세한 설명으로 더욱 명백해질 것이다. 이에 앞서, 본 명세서 및 청구범위에 사용된 용어나 단어는, 발명자가 그 자신의 발명을 가장 최선의 방법으로 설명하기 위해 용어의 개념을 적절하게 정의할 수 있다는 원칙에 입각하여 본 고안의 기술적 사상에 부합하는 의미와 개념으로 해석되어야만 한다.The above features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. Prior to this, the terms or words used in the present specification and claims are based on the principle that the inventor can appropriately define the concept of the term in order to explain the invention in the best way. It should be interpreted as meanings and concepts corresponding to
이하, 첨부된 도면을 참조하여 본 발명의 차량의 시동시 난방 제어방법을 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings illustrating a heating control method at the start of the vehicle of the present invention.
본 발명에 의한 차량의 시동시 난방 제어방법은, 차량이 시동된 후 공조장치를 작동시키면 난방기동제어 진입조건에 해당되는지를 확인하는 단계와; 난방기동제어 진입조건에 해당되면 PTC 히터가 작동중인지를 확인하고 그렇지 않으면 자동 제어를 실시하는 단계와; PTC 히터가 작동중이면 일정 시간 동안 특정제어를 실시한 후 자동제어를 실시하고 그렇지 않으면 난방기동제어 해제조건을 만족할 때까지 난방기동제어를 실시하는 단계와; 난방기동제어 해제조건을 만족하면 난방기동제어를 중지하고 자동제어를 실시하는 단계를 포함하여 구성된다.The heating control method at the start of the vehicle according to the present invention includes the steps of: checking whether the heating start control entry condition is activated when the air conditioner is operated after the vehicle is started; Checking whether the PTC heater is in operation when the heating start control entry condition is met; otherwise, performing automatic control; Performing specific control for a predetermined time if the PTC heater is in operation, then performing automatic control, and otherwise heating heating control until the heating start control releasing condition is satisfied; If the heating start control release condition is satisfied, the step includes stopping the heating start control and performing automatic control.
여기서, 상기 난방기동제어 진입조건은 공조장치를 자동제어모드로 제어시 플로어 토출모드인 상태에서 외기온이 10℃ 이하이면서, 냉각수온이 73℃ 이하인 조건을 모두 만족하는 것을 의미한다. 그리고, 상기 난방기동제어 해제조건은 상기 난방기동제어 진입조건 중 어느 한가지만이라도 벗어나는 것을 의미한다.Here, the heating start control entry condition means that the outside air temperature is 10 ° C. or less and the cooling water temperature is 73 ° C. or less while the air conditioner is controlled in the automatic control mode. The heating start control releasing condition means that any one of the heating start control entry conditions deviates.
또한, 상기 특정제어는 블로워 전압을 로우로 설정한 상태에서 디프로스트 토출모드로 소정 시간동안, 예를 들어 20초 동안 공조제어하는 것을 의미한다.In addition, the specific control means the air conditioning control for a predetermined time, for example, 20 seconds in the defrost discharge mode with the blower voltage set to low.
상기와 같이 구성된 본 발명의 차량의 시동시 난방 제어방법은 PTC 히터가 작동중이면 난방기동제어를 실시하지 않고 특정 제어를 실시한 후 자동제어를 실시하도록 함으로써 조기 난방이 가능하게 한다.The heating control method at start-up of the vehicle of the present invention configured as described above enables early heating by performing specific control without performing heating start control if the PTC heater is in operation.
차량이 시동된 후 공조장치를 작동시키면 난방기동제어 진입조건에 해당되는지를 확인한다. 이때, 난방기동제어 진입조건에 해당되면 PTC 히터가 작동중인지를 확인한다. PTC가 작동중이면 약 20초 동안만 블로워 전압을 로우로 설정한 상태에서 디프로스트 토출모드로 공조제어한 후, 바로 자동제어를 실시한다. 물론, 난방기동제어 진입조건에 해당되지 않으면 곧바로 자동제어를 실시한다. If the air conditioner is operated after the vehicle is started, check if the condition of the heating start control is met. At this time, if the heating start control entry condition is met, check whether the PTC heater is operating. When the PTC is in operation, the air conditioning control is performed in the defrost discharge mode with the blower voltage set to low only for about 20 seconds, and then the automatic control is performed immediately. Of course, if the heating start control entry conditions are not met, automatic control is performed immediately.
따라서, 자동제어로 진입하는 시간이 짧아지게 되고 이는 조기 난방이 가능함을 의미한다. 자동제어는 블로워 전압을 로우보다 높은 전압으로 설정하게 되므 로 풍량이 증대되어 공기를 실내로 토출하게 되므로, 냉각수온이 일정 온도 이상이 경우는 물론 초기 난방시 PTC 히터에 의해 데워진 공기를 실내로 토출하게 되어 조기 난방이 이루어지게 된다.Therefore, the time to enter the automatic control is shortened, which means that early heating is possible. The automatic control sets the blower voltage to a voltage higher than the low, so the air volume increases and the air is discharged to the room. Therefore, the cooling water is discharged to the room during the initial heating as well as when the cooling water temperature is over a certain temperature. This leads to premature heating.
그리고, 난방기동제어 진입조건에 해당되면서 PTC 히터가 작동중이 아니면 난방기동제어를 실시한다. 난방기동제어를 실시하면 송풍량이 최소로 유지되어 냉각수의 온도가 상승하게 되므로, 제어부는 상승되고 있는 냉각수의 온도가 난방기동제어 해제조건을 만족하는지를 확인한다. 냉각수의 온도가 난방기동제어 해제조건을 만족하면 난방기동제어를 중지하고 자동제어를 실시하게 된다.If the PTC heater is not operating while the heating start control entry condition is met, the heating start control is performed. When the heating start control is performed, the air flow is kept to a minimum, and the temperature of the cooling water rises. Therefore, the controller checks whether the temperature of the rising cooling water satisfies the heating start control release condition. When the temperature of the coolant satisfies the condition for releasing the heating start control, the heating start control is stopped and automatic control is performed.
이상에서는 본 발명의 바람직한 실시 예를 설명하였으나, 본 발명의 범위는 이같은 특정 실시 예에만 한정되지 않으며, 해당분야에서 통상의 지식을 가진자라면 본 발명의 특허청구범위 내에 기재된 범주 내에서 적절하게 변경이 가능할 것이다.Although the preferred embodiments of the present invention have been described above, the scope of the present invention is not limited to such specific embodiments, and those skilled in the art may appropriately change within the scope of the claims of the present invention. This will be possible.
이상에서 설명한 바와 같이 본 발명의 차량의 시동시 난방 제어방법에 따르면, 난방기동제어 진입조건에 해당되더라도 PTC 히터가 작동중이면 난방기동제어를 실시하는 대신에 특정제어를 실시함으로써 자동제어를 실시하기까지의 시간이 단축되어 조기 난방이 가능해지는 효과가 있다.As described above, according to the heating control method at start-up of the vehicle of the present invention, if the PTC heater is in operation even if the heating start control entry conditions are met, the automatic control is performed by performing specific control instead of the heating start control. The time required to shorten the early heating is effective.
또, 본 발명의 차량의 시동시 난방 제어방법에 따르면, 난방기동제어의 진입조건 및 해제조건이 특정되어 있으므로 난방기동제어가 제한적으로만 이루어지게 되어 PTC 히터의 활용도를 최대화할 수 있는 다른 효과가 있다.In addition, according to the heating control method at the start of the vehicle of the present invention, since the entry condition and the release condition of the heating start control are specified, only the heating start control is limited, so that there is another effect of maximizing the utilization of the PTC heater. have.
