Description

자동차 오토 밋션 자동오일교환장치의 제어방법{Method for controlling exchanger of automatic transmission oils}Method for controlling exchanger of automatic transmission oils

본 발명은 자동차의 오토 밋션(Auto trasmissi작동)용 오일을 자동으로 교환해 주는 자동오일교환장치의 제어방법에 관한 것으로, 보다 상세하게는 상기 자동오일교환장치를 이용하여 오토 밋션에서 구유를 배출하고, 신유를 주유함에 있어서, 구유의 배출 및 신유의 주유를 자동으로 비교, 제어하여 교환하는 자동오일교환장치의 제어방법에 관한 것이다.The present invention relates to a control method of an automatic oil changer for automatically replacing oil for an auto transmission (Auto trasmissi operation) of a vehicle, and more particularly, to discharge troughs from an automission using the automatic oil changer. The present invention relates to a control method of an automatic oil exchange device for automatically comparing, controlling and exchanging the discharge of trough and the refueling of fresh oil.

일반적으로 자동차용 오토 밋션에는 토오크 컨버터와 밋션의 작동을 위한 오일이 담겨 있는데, 이 오일은 주기적으로 교환이 되어야 하는 바, 보통 오토 밋션의 구유를 배출하고 신유를 공급시, 공급되는 신유가 밋션 내부에서 구유와 희석되기 때문에 완전한 오일 교환을 위해서는 신유가 과다 배출되어 비경제적인 문제가 있었다.In general, automotive auto missions contain oil for the operation of torque converters and missions. These oils need to be replaced periodically. Usually, when the oil is discharged and the new oil is supplied, new oil is supplied inside the mission. Due to the dilution with mangers in the country, there was an uneconomical problem because of excessive discharge of fresh oil for complete oil change.

또한, 밋션오일 점검구와 레벨게이지(dipstick)가 없는 차종(무쏘, 라노스) 등은 오일교환후 오일 교환량을 정확히 확인할 방법이 없었으며, 차량마다 구유의 배출속도가 제각기 달라, 상기 구유의 배출속도가 빠를 때에는 구유배출구를 일시 차단하였다가 다시 재 개방하며, 구유배출속도가 너무 느릴때에는 신유주입 모터펌프를 일시 차단하였다가 다시 신유를 주입하는 등의 작업이 필요하나 작업자의 감각에 의존하기에는 어려운 문제점이 있으며, 작업이 마무리 될때까지 다른 업무를 볼 수 없으므로 불필요한 시간의 낭비가 많다.In addition, the mission oil checker and the vehicle without level gauge (Musso, Lanos), etc., had no way of accurately checking the amount of oil change after oil change, and the discharge speed of the trough varies depending on the vehicle. When it is fast, it is necessary to temporarily shut off and reopen the trough, and when the trough is too slow, it is necessary to temporarily shut off the new oil injection motor pump and inject new oil again, but it is difficult to rely on the operator's senses. There is a lot of unnecessary time, because you can not see other tasks until the work is finished.

이에 본 출원인은 상기의 문제점을 다소 해소할 수 있는 "자동차의 오토 밋션 자동오일교환장치"를 선출원하여 공개특허공보 2001-99142호로 개시된 바 있으며, 본 발명은 상기 자동오일교환장치의 제어방법에 관한 발명으로서, 자동차의 오토 밋션용 오일을 교환함에 있어서, 신유의 불필요한 소모를 최대한 줄이고, 차량마다 제각기 다른 구유배출속도와 상관없이 정확하게 오일교환 설정값에 도달 할 수 있도록 하며, 이를 위하여 구유배출구의 개방과 차단 및 신유주입 모터펌프의 정지와 작동을 자동으로 할 수 있도록 함에 본 발명의 목적이 있다.In this regard, the present applicant has been disclosed in Korean Patent Laid-Open Publication No. 2001-99142, which discloses an "automatic transmission automatic oil exchange device for automobiles" which can solve the above problems, and the present invention relates to a control method of the automatic oil exchange device. In order to reduce the unnecessary consumption of new oil as much as possible, it is possible to accurately reach the oil change setpoint regardless of different trough discharge rates for each vehicle, and to open the trough outlet for this purpose. It is an object of the present invention to automatically shut off and stop and operate the new oil injection motor pump.

이때, 오토 밋션(10) 내부의 오일의 온도를 측정하여 오일의 팽창량을 계산하고, 오일교환 설정값을 작업자가 직접 입력설정한 교환값에 합산되어 자동설정되도록 한다. 오일교환 설정값이 설정된 후 오토 밋션(10)의 구유배출밸브(32)를 개방하면, 구유는 자중과 오토밋션(10)의 펌프의 힘에 의해 자동오일교환장치의 구유배출탱크(34)로 배출된다.At this time, the expansion of the oil is calculated by measuring the temperature of the oil inside the auto-mission 10, and the oil change setting value is automatically added to the exchange value set by the operator and set automatically. When the oil discharge valve 32 of the automatic transmission 10 is opened after the oil change setting value is set, the manger is discharged to the oil discharge tank 34 of the automatic oil change device by the weight of the self and the force of the pump of the automatic transmission 10. Discharged.

그러나, 이렇게 구유가 배출되는 동안 신유를 공급하기 위한 신유주입 모터펌프(46)는 정지된 상태가 되어 있는데, 그 이유는 구유배출과 동시에 신유주입 모터펌프(46)를 작동하면, 너무 많은 신유가 오토 밋션(10) 내부에서 구유와 희석이 되어서 완벽한 오일 교환을 위하여 오토 밋션(10) 내부의 오일을 배출시, 신유까지 배출되어 많은 신유가 소모되기 때문이다. 따라서 구유배출량이 유량계에 의하여 초기배출 설정량만큼 배출되는 것이 감지되면, 그때 비로소 신유주입 모터펌프(46)가 작동되어 신유를 공급하도록 하여 신유의 낭비를 최소화할 수 있다.However, the new oil injection motor pump 46 for supplying new oil is stopped while the trough is discharged. The reason is that when the new oil injection motor pump 46 is operated at the same time as the trough discharge, too much new oil This is because when the oil inside the auto mission 10 is discharged to the new oil to be completely diluted with the trough in the auto mission 10, the new oil is discharged until the new oil is consumed. Therefore, when it is detected that the trough discharge amount is discharged by the initial discharge set amount by the flow meter, the new oil injection motor pump 46 is operated at that time to supply new oil to minimize the waste of new oil.

이렇게 모터펌프(46)가 작동되면, 본 발명에 따라 구유배출속도와 신유주입속도를 비교하여 세가지 결과(①신유주입속도가 큰 경우, ②두 속도가 동일한 경우, ③구유배출속도가 큰 경우)에 따라, 구유배출밸브(32)를 자동으로 차단ㆍ개방하거나 또는 신유주입펌프(46)를 자동으로 작동ㆍ정지하면서, 구유배출량 및 신유주입량을 오일교환 설정값과 비교하여 구유배출밸브(32)를 차단(순환밸브(48)를 개방)하여 오일이 순환상태로 되도록 함과 아울러 신유주입 모터펌프펌프(46)를 정지한 후 부저음을 울려 작업이 완료 되었음을 작업자에게 알려주면, 작업자는 자동오일교환장치를 탈거하여 오일교환작업을 마무리 한다.When the motor pump 46 is operated in this way, according to the present invention, the result of comparing the trough discharge speed and the new oil injection speed is three results (① when the new oil injection speed is large, ② when the two speeds are the same, and ③ when the trough discharge speed is large). According to this, the trough discharge valve 32 is automatically shut off and opened, or the new oil injection pump 46 is automatically operated and stopped, while the trough discharge amount and the fresh oil inflow amount are compared with the oil exchange setting value, and the trough discharge valve 32 To shut off (opening the circulation valve 48) so that the oil is in a circulating state, stop the new oil injection motor pump pump 46, sound a buzzer and inform the worker that the work is completed. Remove the device to complete the oil change.

도 5a는 본 발명에 의한 오일교환장치의 제어과정의 초기 일부의 제어과정을 도시한 흐름도이며, 도 5b는 상기 속도비교단계의 비교결과 신유주입속도가 큰 경우의 제어과정을, 도 5c는 신유주입속도와 구유배출속도가 동일한 경우의 제어과정을, 도 5d는 구유배출속도가 더 큰 경우의 제어과정을 각각 설명한 것이다.Figure 5a is a flow chart showing a control process of the initial part of the control process of the oil changer according to the present invention, Figure 5b is a control process when the new oil injection speed is large as a result of the comparison of the speed comparison step, Figure 5c The control process when the injection speed and the trough discharge speed are the same, and FIG. 5D illustrates the control process when the trough discharge speed is larger, respectively.

먼저, 오토밋션(10)의 구유를 배출하고 신유를 공급하여 교환할 오일 교환 설정값을 작업자가 자동오일교환장치에 미리 입력 설정하여(S30) 셋팅한다. 이때, 상기 오일교환값은 구유의 온도를 측정하여(S10) 구유의 팽창량을 계산(S20)하고 그에 따라 자동으로 재설정되도록 하는 단계(S31)가 더 포함될 수 있다.First, the operator discharges the manger of the automatic transmission 10 and supplies fresh oil to set the oil exchange setting value to be exchanged in advance in the automatic oil change device (S30). In this case, the oil exchange value may further include a step (S31) of measuring the temperature of the trough (S10) to calculate the expansion amount of the trough (S20) and automatically reset accordingly.

그리고, 상기 자동오일교환장치의 배출라인(18)과 연결된 구유배출밸브(32)를 개방(S40)하고, 신유주입 모터펌프(46)를 작동(S60)시키는데, 이 때 구유배출밸브(32)를 통해 배출되는 구유의 배출량을 체크하여(S50) 미리 설정해 놓은 초기배출 설정량과 비교하여 같아지게 될 때 신유주입 모터펌프(46)를 작동(S60)하며, 구유배출량이 초기배출 설정값에 미치지 않는 경우에는 신유주입 모터펌프(46)를 작동하지 않도록 제어한다.Then, the trough discharge valve 32 connected to the discharge line 18 of the automatic oil exchange device is opened (S40), and the new oil injection motor pump 46 is operated (S60), at which time the trough discharge valve 32 By checking the discharge of the trough discharged through (S50) when the same as compared with the preset initial discharge set amount is operated the new oil injection motor pump 46 (S60), and the trough discharge amount does not reach the initial discharge set value If not, the new oil injection motor pump 46 is controlled to not operate.

상기와 같이 신유주입 모터펌프(46)가 작동되면(S60), 차량의 용량마다 제각기인 구유배출속도를 체크하고, 계절에 따라 점도가 유동적인 신유의 속도를 체크하여 비교(S70)하여 그 결과에 따라 다음의 세가지 경우로 나뉘어 제어된다.When the new oil injection motor pump 46 is operated as described above (S60), the respective trough discharge speeds are checked for each capacity of the vehicle, and the speeds of the new oils with viscosity change according to the season are checked (S70). The control is divided into the following three cases.

먼저, 신유주입속도가 구유배출속도 보다 빠르면, 신유주입 모터펌프(46)를일단 정지시키고(S80, 물론 이 때에도 구유의 배출은 계속되는 상태임), 신유주입량과 구유배출량을 비교하여(S90) 신유주입량이 구유배출량 보다 적으면, 다시 신유주입 모터펌프(46)를 작동시켜(S100) 신유의 주입을 재개함과 동시에, 신유주입량과 오일교환 설정값을 비교(S110)하여 신유주입이 오일교환 설정값을 넘지 않도록 제어한다(S120). 만약, 신유주입량이 구유배출량에 미치지 않는 경우에는 계속 구유를 배출하면서 구유배출량이 주입된 신유의 양과 같아지는지를 체크한다. 이렇게 하면서 신유주입이 구유배출량에 비하여 과도해지지 않고 적절한 균형을 이루도록 제어한다.First, when the new oil injection speed is faster than the trough discharge speed, the new oil injection motor pump 46 is once stopped (S80, of course, the discharge of the trough continues), and the new trough injection amount and trough discharge amount are compared (S90) If the injection amount is smaller than the discharge amount of the trough, the new oil injection motor pump 46 is operated again (S100) to resume the injection of fresh oil, and the new oil injection amount and the oil change setting value are compared (S110) to set the oil change. Control not to exceed the value (S120). If the amount of new oil injection does not reach the amount of manure discharge, it is continuously discharged and it is checked whether the amount of manure discharge equals the amount of fresh oil injected. In doing so, it ensures that the new oil injections are in proper balance and not excessively compared to manure discharges.

이렇게 순환과정을 거쳐, 신유주입량이 오일교환 설정값에 도달되면(S110), 신유주입 모터펌프(46)를 정지시킨다(S120). 그리고, 구유배출량과 오일교환 설정값을 비교하여(S130) 상기 오일교환 설정값에 도달하면, 구유 배출구를 차단(S140, 즉 순환밸브의 개방)함으로써 오일교환이 마무리 된다.After the circulation process, when the fresh oil injection amount reaches the oil exchange setting value (S110), the new oil injection motor pump 46 is stopped (S120). When the oil exchange setting value is reached by comparing the discharge amount of the trough and the oil change setting value (S130), the oil change is completed by blocking the trough discharge port (S140, that is, opening the circulation valve).

만약, 상기 속도비교단계의 비교결과, 신유주입속도가 구유배출속도와 같으면, 도 5c에 도시된 바와 같이, 구유배출량이 오일교환 설정값에 도달했는지를 판단(S220)하여, 구유배출구를 차단(S230, 즉 순환밸브 개방)하고, 이어서 신유주입량이 오일교환 설정값에 도달도달했는지를 판단(S240)하여, 신유주입 모터펌프(46)를 정지시킴으로써(S250) 오일교환을 마무리한다.If, as a result of the comparison of the speed comparison step, if the new oil injection speed is equal to the trough discharge speed, as shown in Figure 5c, it is determined whether the trough discharge amount reaches the oil exchange setting value (S220), blocking the trough outlet ( S230, that is, the circulation valve is opened, and then it is judged whether or not the fresh oil injection amount has reached the oil change setting value (S240), and the oil change is completed by stopping the fresh oil injection motor pump 46 (S250).

한편, 상기 속도비교단계의 비교결과, 구유배출속도가 신유주입속도보다 크면, 구유배출밸브(32)를 차단하고(S150) 순환밸브(48)를 개방함으로써, 오일이 순환상태가 되도록 한다(물론 이 때에도 신유주입은 계속되는 상태임). 그리고, 신유주입량과 구유배출량을 비교하여(S90) 구유배출량이 신유주입량보다 적으면, 다시 구유배출밸브를 개방하여(S170) 구유의 배출을 재개함과 동시에, 구유의 배출량과 오일교환 설정값을 비교(S180)하여 구유배출이 오일교환 설정값을 넘지 않도록 밸브를 제어한다(S190). 만약, 구유배출량이 신유주입량에 미치지 않는 경우(S160)에는 계속 신유를 주입하면서 신유주입량이 배출된 구유의 양과 같아지는지를 체크한다. 이렇게 하면서 구유배출이 신유주입량에 비하여 과도해지지 않고 적절한 균형을 이루도록 제어한다.On the other hand, as a result of the comparison of the speed comparison step, if the trough discharge speed is greater than the new trough injection speed, the trough discharge valve 32 is blocked (S150) by opening the circulation valve 48, so that the oil is in a circulating state (of course) In this case, new injections continue.) In addition, if the amount of new oil injection is lower than the amount of new oil injection (S90), when the amount of oil discharge is smaller than the amount of new oil injection, the oil discharge valve is opened again (S170), and the discharge of the oil is resumed, and the discharge of the oil is adjusted and the oil exchange setting value is increased. Comparing (S180) and controlling the valve so that the discharge of the trough does not exceed the oil change set value (S190). If the amount of manure discharge does not reach the amount of new oil injection (S160), it is checked whether the amount of new oil injection is equal to the amount of discharged manger while continuing to inject fresh oil. In doing so, the manure discharge is controlled so as not to be excessive compared to the fresh oil injection, but to achieve an appropriate balance.

이런 과정을 거쳐, 구유배출량이 오일교환 설정값에 도달되면(S180), 구유배출구를 차단(S190)한 후, 신유주입량이 오일교환 설정값에 도달하게 되면(S200), 신유주입 모터펌프(46)를 정지(S210)함으로써, 역시 오일교환을 마무리한다.Through this process, when the trough discharge amount reaches the oil change set value (S180), after closing the trough discharge port (S190), when the fresh oil injection amount reaches the oil change set value (S200), the new oil injection motor pump (46) ) By stopping (S210), the oil change is finished again.
