CLUTCH ENGAGEMENT CONTROL DEVICE

This invention provides a clutch engagement control system allowing quick clutch engagement without shock even if the point to start engaging the clutch varies. A clutch engagement control system 100 for engaging a friction clutch 1 by means of an actuator 3, comprises a magnetostrictive sensor 71 for detecting the state of power transmission over the friction clutch 1, engages the friction clutch 1 at first engagement velocity until the magnetostrictive sensor 71 detects the start of the power transmission, and changes the engaging velocity to second engagement velocity lower than the first engagement velocity when the magnetostrictive sensor 71 detects the start of the power transmission such that the friction clutch 1 starts transmitting power after no power transmitted over the friction clutch 1, and the power transmissibility is gradually enhanced.
