Description

연료전지차량의 공기필터교환주기 알림방법{Air filter exchange cycle notify method in fuel cell vehicle} BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fuel cell vehicle,

본 발명은 연료전지차량에 관한 것으로, 특히 연료전지차량에 적용된 공기필터교환주기를 알려주는 방법에 관한 것이다.Field of the Invention [0002] The present invention relates to a fuel cell vehicle, and more particularly, to a method of informing an air filter replacement period applied to a fuel cell vehicle.

일반적으로 연료전지차량은 내연기관과 달리 연료전지내부의 표면에서 일어나는 화학반응에 의하여 생성된 전기를 이용함으로써, 외부에서 유입되는 공기를 청결하게 유지하는 것을 필히 요구한다. Unlike an internal combustion engine, a fuel cell vehicle generally requires electricity generated by a chemical reaction occurring on the surface of the interior of a fuel cell to keep the air flowing from the outside clean.

이를 위해 연료전지차량의 공기공급계는 운전자의 요구 출력에 따라 구동되는 공기블로워를 통해 흡입되는 외기는 필터를 통해 유입시키고, 유량센서로 파악된 유입공기량을 이용해 공기블로워의 회전속도를 조절하며, 공기블로워의 회전속도는 제어기를 통하여 회신된다.To this end, the air supply system of the fuel cell vehicle controls the rotation speed of the air blower by using the amount of inflow air detected by the flow sensor, The rotation speed of the air blower is returned through the controller.

하지만, 공기필터오염은 연료인 공기중의 산소유입을 방해해 연료전지출력저하를 가져오고, 공기필터 오염으로 발생되는 공기블로워 과부하는 연료전지내부로 필터의 이물질 일부를 유입시킬 위험성을 높이게 된다.However, the contamination of the air filter obstructs the inflow of oxygen in the air, which results in the deterioration of the output of the fuel cell, and the overload of the air blower caused by the contamination of the air filter increases the risk of introducing a part of foreign matters into the fuel cell.

이로 인하여 연료전지 차량은 공기필터오염을 정확히 확인하고, 오염된 공기 필터를 제때에 교환하는 적기성이 매우 중요하다.Therefore, it is very important for the fuel cell vehicle to confirm air filter contamination accurately and to replace the polluted air filter in time.

공기필터오염을 감지하고 교환주기를 체크하는 방식은 다양하게 구현될 수 있으며, 일례로 차량 운행거리나 운행조건으로 필터교환시기를 판단하는 방법이나 또는 차량 운행시간으로 필터교환시기를 판단하는 방법등이 있다.The method of detecting the air filter contamination and checking the replacement cycle can be variously implemented. For example, there is a method of determining the filter replacement time based on the distance or the driving condition of the vehicle, or a method of determining the filter replacement time .

하지만, 상기와 같은 방법들은 공기필터교환을 위한 최적화된 방식이 될 수 없는데, 이는 필터교환시기를 차량운행거리나 운행조건으로 판단하는 경우 차량 운행 환경에 따라 상이한 필터오염상태를 나타낼 수밖에 없는 측면을 갖기 때문이다.However, the above methods can not be an optimized method for exchanging the air filter. This is because when the filter replacement time is judged as the traveling distance or the driving condition of the vehicle, .

또한, 필터교환시기를 차량 운행시간으로 판단하는 경우도 차량운행거리나 운행조건으로 판단할때와 동일하며 특히, 짧은 운행시간에서도 외부유입공기가 많은 고출력운행시나 또는, 긴 운행시간에서도 아이들운행구간이 많은 경우 공기필터교환을 비효율적으로 할 수밖에 없는 측면을 갖는다.In addition, even when the filter replacement time is determined as the vehicle operation time, the same operation is performed as in the case of determining the vehicle operation distance and the operation condition. Particularly, even when the operation time is short or the high- The air filter has to be ineffectively replaced.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 외부공기를 흡입하는 공기블로워쪽 부하변화로 필터내 이물질 축적정도를 판단함으로써, 공기필터교환시기를 정확히 판단해 비효율적인 필터교환을 예방하고, 이물질로 인한 연료전지 화학반응저하를 방지해 내구성도 높일 수 있는 연료전지차량의 공기필터교환주기 알림방법을 제공함에 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a method and apparatus for determining the degree of accumulation of foreign matter in a filter by changing a load on an air blower sucking outside air, The present invention also provides a method of notifying a replacement period of an air filter of a fuel cell vehicle, which can prevent deterioration of a fuel cell chemical reaction due to a foreign substance and enhance durability.

상기와 같은 목적을 달성하기 위한 본 발명은, 연료전지차량의 공기필터교환주기 알림방법은 공기필터를 거친 외부공기를 연료전지쪽으로 공급하는 공기블로워쪽 부하변화로 공기부하량 증가의 감소시기를 판단해, 공기필터교환시기를 정하는 것을 특징으로 한다.In order to accomplish the above object, the present invention provides a method for informing a replacement period of an air filter of a fuel cell vehicle, comprising: determining a decrease period of an air load increase due to a change in a load of an air blower supplying outside air through an air filter to a fuel cell , And the air filter replacement timing is determined.

상기 공기블로워는 적어도 1단계이상으로 구동속도를 분류하고, Wherein the air blower classifies the driving speed by at least one step,

상기 분류된 구동속도별로 상기 공기블로워가 구동될때, 각 구동속도에서 공기필터를 지난 공기흡입량을 측정하며,The air suction amount passing through the air filter at each driving speed is measured when the air blower is driven according to the classified driving speed,

상기 공기흡입량 측정시마다 상기 공기블로워의 회전속도를 측정하고,Measuring a rotation speed of the air blower every time the air suction amount is measured,

상기 공기블로워의 구동속도운영과 상기 공기흡입량 측정과 상기 회전속도 측정을 반복하는 로직루프를 수행하며,Performing a logic loop that repeats the operation of the air blower and the air suction amount measurement and the rotation speed measurement,

반복수행 후 상기 공기블로워의 공기부하량 증가의 감소시기로 공기필터교환시기임을 판단하고,Determining that the air filter is to be replaced at a timing of decreasing the air load increase of the air blower after the repeated execution,

상기 공기필터교환시기일 때, 공기필터교환시기임을 알려주는 과정으로 수행되는 것을 특징으로한다.And a step of informing that the air filter is being replaced when the air filter is being replaced.

상기 공기필터교환시기 판단은 상기 공기블로워의 분류된 구동속도와, 상기 공기블로워의 분류된 구동속도에 따라 반복수행된 상기 로직루프를 통해 얻어진 공기흡입량 측정시 측정된 상기 공기블로워의 회전속도값을 이용해 결정한다. The air filter replacement timing is determined based on the classified driving speed of the air blower and the rotational speed value of the air blower measured during the air suction amount measurement obtained through the logic loop repeatedly performed according to the classified driving speed of the air blower Use.

상기 공기필터교환시기 판단은 분류된 구동속도 단계별로 각각 판단한다.The determination of the air filter replacement period is made for each of the classified driving speed steps.

상기 공기필터교환시기 판단은 로직루프의 반복수행횟수나, 상기 공기블로워의 분류된 구동속도와 상기 공기블로워의 회전속도값을 이용해 결정된다. The air filter replacement timing is determined using the number of iterations of the logic loop, the classified driving speed of the air blower, and the rotational speed of the air blower.

상기 로직루프는 상기 공기블로워의 구동속도가 아이들L1 상태와, 중간출력L2 상태 및 고출력L3 상태로 구분되고, 상기 아이들L1시 측정된 공기흡입량F1과 공기흡입량 측정시 공기블로워 회전속도S1를 측정하며, 상기 중간출력L2시 측정된 공기흡입량F2과 공기흡입량 측정시 공기블로워 회전속도S2를 측정하고, 상기 고출력L3시 측정된 공기흡입량F3과 공기흡입량 측정시 공기블로워 회전속도S3를 측정하는 과정을 반복수행한다. In the logic loop, the driving speed of the air blower is divided into an idle state L1, an intermediate output state L2 and a high output state L3, and the air suction amount F1 measured at the idle time L1 and the air blower rotation speed S1 measured at the time of measuring the air suction amount are measured The air suction amount F2 measured at the intermediate output L2 and the air blower rotation speed S2 at the time of measuring the air suction amount are measured and the air suction amount F3 measured at the high output L3 and the air blower rotation speed S3 measured at the air suction amount measurement are repeated .

상기 로직루프는 상기 아이들L1 구동과 중간출력L2 구동 및 고출력L3 구동을 순차적으로 수행한다. The logic loop sequentially performs the idle L1 driving, the intermediate output L2 driving, and the high output L3 driving.

이러한 본 발명에 의하면, 필터내 이물질 축적정도에 따라 변화되는 공기블로워쪽 부하변화를 이용해 정확한 공기필터교환시기를 판단하므로, 비효율적인 필터교환을 예방하고 연료전지쪽 내구성도 높일 수 있는 효과를 갖는다.According to the present invention, it is possible to prevent an inefficient replacement of a filter and increase the durability of a fuel cell by determining a correct air filter replacement timing by using a change in load on the air blower that varies depending on the degree of accumulation of foreign matter in the filter.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명하며, 이러한 실시예는 일례로서 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자가 여러 가지 상이한 형태로 구현될 수 있으므로, 여기에서 설명하는 실시예에 한정되지 않는다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which illustrate exemplary embodiments of the present invention. The present invention is not limited to these embodiments.

도 1은 본 발명에 따른 연료전지차량의 공기필터교환주기 알림방법의 흐름도를 나타낸다.FIG. 1 is a flowchart of a method of notifying an air filter replacement period of a fuel cell vehicle according to the present invention.

도시된 바와 같이, 연료전지쪽으로 공급되는 외부공기를 거르는 공기필터 교환주기설정을 위해, 외부공기를 흡입하는 공기블로워의 구동속도를 적어도 1단계이상으로 분류한다.As shown in the figure, the driving speed of the air blower for sucking the outside air is divided into at least one step for setting the replacement period of the air filter for filtering the outside air supplied to the fuel cell.

본 실시예에서 공기블로워의 구동속도분류는 공기블로워 아이들(Idle)상태와, 중간출력상태 및 고출력상태로 구분하며, 아이들을 L1, 중간출력을 L2, 고출력을 L3로 정의한다.In this embodiment, the driving speed classification of the air blower is divided into an air blower idle state, an intermediate output state and a high output state, and defines the idle as L1, the intermediate output as L2, and the high output as L3.

이어, 전체단계를 한번 수행할 때마다 1회씩 카운트되는 로직루프를 수행하며, 공기블로워는 아이들L1과 중간출력L2 및 고출력L3으로 구분되어 각각 구동된다.The air blower is divided into an idle L1, an intermediate output L2, and a high output L3, and is driven by a logic loop, which is counted once every time the entire step is performed.

공기블로워가 각 단계로 구동되면 유량센서는 각 단계에 따른 공기흡입량을 측정하며, 상기 유량센서값은 공기블로워 제어기(또는 ECU)를 이용해 산출한다.When the air blower is driven in each step, the flow sensor measures the amount of air sucked according to each step, and the flow sensor value is calculated using an air blower controller (or ECU).

유량센서를 통해 산출된 공기흡입량은 아이들L1구동시 공기흡입량을 F1으로, 중간출력L2구동시 공기흡입량을 F2로, 고출력L3구동시 공기흡입량을 F3로 정의한다.The air intake amount calculated through the flow sensor is defined as F1, the air intake amount when driving the intermediate output L2 is F2, and the air intake amount when the high output L3 is driven F3 when the idle L1 is driven.

공기블로워 제어기(또는 ECU)는 이러한 공기흡입량측정과 동시에 공기블로워쪽 회전속도도 함께 측정하고, 공기흡입량F1측정시 블로워속도를 S1으로, 공기흡입량F2측정시 블로워속도를 S2로, 공기흡입량을 F3측정시 블로워속도를 S3로 각각 정의한다.The air blower controller (or ECU) simultaneously measures the air suction amount and the rotation speed at the air blower. The blower speed at the time of measuring the air suction amount F1 is S1, the blower speed at the time of measuring the air suction amount F2 is S2, And the blower speed at the measurement is defined as S3.

이어, 상기와 같이 각각 정의된 공기블로워 구동속도 L1, L2, L3와, 각 구동속도에 따른 공기흡입량을 F1, F2, F3 및 공기흡입량측정시 공기블로워 회전속도 S1,S2,S3가 산출되면, 전체단계를 한번 수행할 때마다 1회씩 카운트되는 로직루프를 수행하면서 공기필터 교환여부를 체크한다.When the air blower driving speeds L1, L2 and L3 respectively defined as described above and the air suction amounts F1, F2 and F3 corresponding to the respective driving speeds and the air blower rotation speeds S1, S2 and S3 at the time of measuring the air suction amount are calculated, It performs a logic loop that is counted once every time the entire step is performed, and checks whether the air filter is exchanged.

상기 로직루프 수행시 공기필터 교환여부에 대한 판단은 로직루프의 전체단계 반복수행횟수나, 또는 공기블로워의 설정분류된 구동속도 L1, L2, L3와, 공기흡입량측정시 공기블로워 회전속도 S1,S2,S3의 관계를 이용해 구현한다.The determination as to whether or not the air filter is exchanged at the time of performing the logic loop may be determined by the number of times of repeating the entire step of the logic loop or by the setting speeds L1, L2, L3 of the air blower and the air blower rotation speeds S1, S2 , And S3.

일례로, 로직루프의 전체단계 반복수행횟수를 10회나 20회로 설정하거나 또는 공기블로워속도인 L1,L2와 S1,S2의 관계를 이용해 구현한다.For example, the total number of times the logic loop is repeated is set to 10 times or 20 times, or the relationship between the air blower speeds L1 and L2 and S1 and S2 is used.

하지만, 공기블로워가 고출력L3으로 구동될때는, 공기블로워 구동속도L3에 대해 공기흡입량을F3 측정시 측정된 공기블로워 회전속도S3간 관계를 이용해 공기필터 교환여부를 판단한다.However, when the air blower is driven by the high output L3, it is determined whether or not the air filter is exchanged by using the relationship between the air blower driving speed L3 and the air blower rotation speed S3 measured at the time of F3 measurement.

상기와 같은 로직루프 수행은 상기 조건에 따라 단계적으로 수행한다.The above logic loop execution is performed stepwise according to the above conditions.

초기에 수행되는 로직루프는 로직루프의 전체단계 반복수행횟수K가 10회를 넘는 K>10조건이거나, 또는 공기블로워의 설정분류된 구동속도 L1에서 공기흡입량F1 측정시 측정된 공기블로워 회전속도S3이 L1>S1조건을 만족하는지 여부를 먼저 판단한다.The initial logic loop is a condition in which the total number of times K of the logic loop is exceeded by more than 10 times, K > 10, or the air blower rotation speed S3 measured in the air suction amount F1 measurement at the air- It is first determined whether or not the L1 > S1 condition is satisfied.

만약, K>10이나 또는 L1>S1조건을 만족하지 않으면 공기부하량 증가의 감소시기로 판단하고, 공기필터교환시기임을 알려준다.If the condition of K> 10 or L1> S1 is not satisfied, it is determined that the air load increase is to be reduced and the air filter change time is indicated.

공기필터교환시기 알림은 다양한 방식으로 구현하지만, 바람직하게는 운전석 클러스터(Cluster)쪽에 경고등을 점멸하는 방식을 이용한다.The notification of when the air filter is exchanged may be implemented in various ways, but preferably, a warning light is blinked on the cluster side of the driver's seat.

하지만, K>10이나 또는 L1>S1조건을 만족하면, 공기블로워를 중간출력L2로 구동하고 다시 로직루프를 반복 수행한다.However, if the condition K > 10 or L1 > S1 is satisfied, the air blower is driven to the intermediate output L2 and the logic loop is repeated again.

로직루프의 반복수행은 그 횟수가 K>20이나 또는 L2>S2조건을 만족할때까지 이다.The iterative execution of the logic loop is until the number of times satisfies the condition K> 20 or L2> S2.

만약, K>20이나 또는 L2>S2조건을 만족하지 않으면 공기부하량 증가의 감소시기로 판단하고, 운전석 클러스터(Cluster)쪽에 경고등을 점멸하는 방식을 이용해 공기필터교환시기임을 알려준다.If the condition of K> 20 or L2> S2 is not satisfied, it is determined that the increase of the air load is to be reduced, and the air filter change time is indicated by flashing the warning light on the cluster side of the driver's seat.

하지만, K>20이나 또는 L2>S2조건을 만족하면, 공기블로워를 고출력L3으로 구동하고 다시 로직루프를 반복 수행한다.However, if the condition K> 20 or L2> S2 is satisfied, the air blower is driven by the high output L3 and the logic loop is repeated again.

이때는 로직루프의 반복수행횟수는 고려하지 않고, 공기블로워 L3>S3 조건만을 고려해 공기필터교환시기에 대한 판단을 한다.In this case, the number of iterations of the logic loop is not considered, and the air filter change time is judged based on only the condition of the air blower L3> S3.

이 과정에서 공기블로워 L3>S3 조건 만족시 공기필터교환시기가 아니므로 로직루프를 마치지만, 만약 공기블로워 L3>S3 조건을 만족하지 않으면 공기부하량 증 가의 감소시기로 판단하고, 운전석 클러스터(Cluster)쪽에 경고등을 점멸하는 방식을 이용해 공기필터교환시기임을 알려준다.If air blower L3> S3 is satisfied, it is not time to replace air filter. If air blower L3> S3 condition is not satisfied, it is determined that it is time to reduce air load increase. The warning light blinks to indicate the air filter replacement time.

이와 같이 본 실시예에서는 공기블로워를 아이들L1 회전과, 중간출력L2 회전 및 고출력L3 회전으로 분류해 구동하고, 각각 L1,L2,L3로 구동한 상태에서 각각에 따른 공기흡입량 F1, F2, F3을 산출함과 동시에 현 블로워 속도 S1, S2, S3도 각각 산출한 다음, 로직루프를 반복수행하면서 상기 L1과 S1, L2와 S2 및 L3와 S3의 관계로 나타나는 공기블로워쪽 부하변화로 공기필터교환시기를 정확히 판단한다.As described above, in this embodiment, the air blower is divided into the idle L1 rotation, the intermediate output L2 rotation, and the high output L3 rotation, and the air suction amounts F1, F2 and F3 And the current blower speeds S1, S2, and S3 are calculated, and then the air filter switching timing is changed according to the air blower load change represented by the relationship of L1, S1, L2 and S2 and L3 and S3 while the logic loop is repeatedly performed. .

이에 따라, 정확한 공기필터교환시기 판단으로 비효율적인 필터교환을 예방하고, 이물질없는 외부공기공급으로 연료전지내구성도 높이게 된다.Accordingly, it is possible to prevent ineffective replacement of the filter by judging the replacement timing of the air filter accurately, and to improve the durability of the fuel cell by supplying foreign air without foreign substance.
