Abstract

〈목적〉 부하의 영향을 받지 않고 정확하게 반 클러치 위치를 학습하고 차량에 있어서 원활 또는 신속한 발진동작을 얻는 것을 가능으로 한다.<Purpose> It is possible to accurately learn the anti-clutch position without being influenced by the load, and to obtain smooth or rapid starting operation in the vehicle.

〈구성〉 공여되는 조작신호 Va에 대해서 클러치 위치 신호 Vf를 피드백하면서 PID 연산부(1-3)에서 계의지연이나 제어성을 가미한 PID 신호 Vs를 생성하는 것으로 한 후, 클러치(3)를 절단할 때, 어느 정도의 경사로 Vmin에서 Vmax로 변화하는 조작신호 Va를 감산기(1-2)로 부여하는 것으로 하고 PID 신호 VS와 클러치 위치신호 Vf 와의 차가 부호가 변화하는 점(부호변환점)을 알아내고 이 부호 변화점의 클러치 스트로크 위치 L를 반 클러치 위치 LS로서 학습한다.<Configuration> The clutch 3 is disconnected after the clutch position signal Vf is fed back to the operating signal Va to be supplied to generate the PID signal Vs incorporating delay or controllability of the system in the PID calculation unit 1-3. In this case, the subtractor 1-2 is given the operation signal Va, which changes from a certain slope V min to V max , and the point at which the difference between the PID signal VS and the clutch position signal Vf changes sign (sign conversion point) is found. The clutch stroke position L at this sign change point is learned as the half clutch position LS.
