There is a problem in that a dirty shift shock occurs due to frequent change of the control logic due to a misjudgment.
따라서 본 발명의 목적은 상기한 문제점을 해결하기 위해 안출된 것으로서, 차량 주행상태에 따른 운전자의 미소한 가속페달 조작에 따른 파워 온/오프 판정은 댐퍼 클러치의 작동상태와 엔진 회전수(Ne) 및 터빈 회전수(Nt)의 관계에 따라 파워 온/오프를 판정하기 위한 자동 변속기의 파워 온/오프 판정방법을 제공하기 위한 것이다.Accordingly, an object of the present invention is to solve the above problems, the power on / off determination according to the driver's micro accelerator pedal operation according to the driving state of the vehicle is the operating state of the damper clutch and the engine speed Ne and It is an object of the present invention to provide a power on / off determination method of an automatic transmission for determining power on / off in accordance with the relationship between the turbine speed Nt.

It consists of 20.

운전자의 가속페달 조작상태에 따라 가변되어 출력되는 온/오프신호를 검출하여 소정의 전기신호를 출력하는 가속페달 스위치(17)를 포함하여 이루어져 있다.And an accelerator pedal switch 17 which detects an on / off signal that is variable and output according to the driver's accelerator pedal operation state and outputs a predetermined electric signal.
상기한 구성에 의해 이루어져 있는 자동 변속기의 파워 온/오프 판정방법을 도2를 참조하여 설명한다.The power on / off determination method of the automatic transmission made up of the above-described configuration will be described with reference to FIG.
차량이 주행을 시작하면 TCU(20)는 운전자의 가속페달 조작상태와 자동 변속기의 동작상태에 따라 검출되는 유온 등에 따라 댐퍼 클러치의 작동상태를 판단한다(S100,S110).When the vehicle starts to travel, the TCU 20 determines the operation state of the damper clutch according to the oil temperature detected according to the driver's accelerator pedal operation state and the automatic transmission operation state (S100 and S110).
상기에서 차량 주행중 댐퍼 클러치가 동작한 경우, TCU(20)는 차량의 엔진 회전수(Ne)와 터빈 회전수(Nt)의 관계를 판단한다(S120).When the damper clutch is operated while driving the vehicle, the TCU 20 determines the relationship between the engine speed Ne and the turbine speed Nt of the vehicle (S120).
즉, 파워의 흐름이 엔진에서 출력된 동력이 자동 변속기에 전달되어 차체를 구동시키는 경우를 파워 온(Power On)이라 하고, 그와 반대로 차체의 구동력이 자동 변속기에 전달되어 엔진으로 전달되는 것을 파워 오프(Power Off)라 한다.That is, a case where the power flow is transmitted from the engine to the automatic transmission to drive the vehicle body is called Power On. On the contrary, the driving force of the vehicle body is transmitted to the automatic transmission to the engine. Called off (Power Off).
따라서 TCU(20)는 엔진 회전수(Ne)가 터빈 회전수(Nt)보다 크거나 같으면 파워 온이라 판정하고, 엔진회전수(Ne)가 터빈 회전수(Nt)보다 작으면 파워 오프라 판정한다.Therefore, the TCU 20 determines that the engine speed Ne is greater than or equal to the turbine speed Nt, and the power is on. If the engine speed Ne is less than the turbine speed Nt, the TCU 20 determines that the power is off.
그러므로 상기 판정단계에서 터빈 회전수(Nt)에서 엔진 회전수(Ne)을 감산 연산한 값이 -50rpm보다 크거나 같으면 파워 오프로 판정한 후, 스로틀 밸브 변화량(△Th)이 설정된 기준값인 3.3%/sec보다 크거나 같은가를 판단한다(S130).Therefore, if the value obtained by subtracting the engine speed Ne from the turbine speed Nt in the determination step is greater than or equal to -50 rpm, it is determined that the power is turned off, and then the throttle valve change amount ΔTh is 3.3% which is the set reference value. It is determined whether greater than or equal to / sec (S130).
상기에서 터빈 회전수(Nt)에서 엔진 회전수(Ne)을 감산 연산한 값이 -50rpm보다 크거나 같고, 스로틀 밸브 변화량(△Th)이 설정된 기준값인 3.3%/sec보다 작은 경우 TCU(20)는 파워 오프(Power Off)라 판정한다(S140).The TCU 20 when the value obtained by subtracting the engine speed Ne from the turbine speed Nt is greater than or equal to -50 rpm and the throttle valve change amount ΔTh is less than the set reference value of 3.3% / sec. It is determined that the power off (Power Off) (S140).
하지만 상기에서 터빈 회전수(Nt)에서 엔진 회전수(Ne)을 감산 연산한 값이 -50rpm보다 크거나 같고, 스로틀 밸브 변화량(△Th)이 설정된 기준값인 3.3%/sec보다 크거나 같은 경우, TCU(20)는 파워 온(Power On)이라 판정한다(S141).However, if the value obtained by subtracting the engine speed Ne from the turbine speed Nt is greater than or equal to -50 rpm, and the throttle valve change amount ΔTh is greater than or equal to the set reference value of 3.3% / sec, The TCU 20 determines that the power is on (S141).
또한 상기에서 터빈 회전수(Nt)에서 엔진 회전수(Ne)을 감산 연산한 값이 -50rpm보다 작으면 TCU(20)는 파워 온(Power On)이라 판정한다.Further, when the value obtained by subtracting the engine speed Ne from the turbine speed Nt is less than -50 rpm, the TCU 20 determines that the power is on.
그러나 상기(S110)에서 댐퍼 클러치가 작동되지 않는 경우, TCU(20)는 도3에 도시되어 있듯이 맵에 설정되어 있는 파워 온/오프 판정선에 따라 파워 온/오프를 판정한다(S111).However, when the damper clutch is not operated in S110, the TCU 20 determines power on / off in accordance with the power on / off determination line set in the map as shown in FIG. 3 (S111).
상기한 실시예는 가장 바람직한 실시예를 설명한 것으로써, 이에 한정되는 것은 아니며, 상기 실시예로부터 용이하게 설명할 수 있는 것도 본 발명에 포함된다.The above embodiments are described as the most preferred embodiments, and the present invention is not limited thereto, and the embodiments can be easily described from the above embodiments.
이상에서와 같이 본 발명의 실시예서 파워 온/오프 판정을 확실히 함으로서, 운전자의 미소한 가속페달 조작상황에도 그에 알맞은 변속제어로직을 사용할 수 있어 비정상적인 변속쇼크를 개선할 수 있고, 엔진 회전수(Ne)의 편차에 따른 파워 온/오프 판정선의 오차를 없앨 수 있어 변속제어의 신뢰성을 향상시킬 수 있는 효과가 있다.As described above, by ensuring the power on / off determination in the embodiment of the present invention, the shift control logic can be used even in the small accelerator pedal operation situation of the driver, it is possible to improve the abnormal shift shock, the engine speed (Ne Since the error of the power on / off determination line due to the deviation of) can be eliminated, the reliability of shift control can be improved.
