POWER TRANSMISSION CONTROL DEVICE FOR VEHICLE

First, the sleeve stroke SSt of a specific sleeve is gradually increased from "0" (after t1) in a state in which a vehicle is stopped, a transmission is in a neutral state (all sleeve strokes SSt = 0 (original position)), a clutch is in a disengaged state (clutch stroke CSt = 0 (original position)), and an engine is operating (engine rotational speed NE > 0). After that, upon determination that "the sleeve stroke SSt has reached a "predetermined value A, at which synchronization operation of a corresponding synchronization mechanism is performed," the sleeve stroke SSt is fixed to the predetermined value A, and an operation of increasing the clutch stroke CSt from "0" in a press engagement direction is started (time t2). An engagement start point CStlearn of the clutch is obtained on the basis of a change in the rotational speed Ni of an input shaft Ai of the transmission after that (time t3). Even in the case where there occurs a phenomenon in which the input shaft of the transmission slightly rotates due to rotation of the engine despite the clutch being in the disengaged state, the engagement start point of the clutch can be obtained reliably.
