<p>PURPOSE:To make stable clutch's on-off operations performable, by installing a device, which detects starting torque of a transmission, and also another device which detects such a control state that clutch transfer torque accords with the transmission's starting torque, and estimating the correction value of clutch learning. CONSTITUTION:With off-motion of a clutch 6, an input shaft 3a of a transmission 3 comes to a stop by dint of rotational resistance. Afterward, time till the input shaft 3a stops is counted, whereby the rotation resistance of the transmission 3 is estimated. Hereat, starting torque of the transmission 3 and the rotational resistance are correlative to each other. Therefore, the learning value of the clutch 6 is corrected with the rotational resistance of the transmission 3 whereby even if the starting torque of the transmission 3 is varied by temperature and environmental conditions, stable on-off operations of the clutch 6 is performable.</p> |
