PROBLEM TO BE SOLVED: To easily decide a hydraulic fluid filling termination point of a clutch by detecting an instantaneous clutch slip and determining time when the value becomes smaller than a value that the average of a prescribed cycle number of the slip is divided by a prescribed factor. SOLUTION: When an operator operates a clutch enable switch 81, an electronic control module 40 detects a difference of input speed and output speed of a clutch 83 as a clutch slip by sensors 42 and 44 and imparts a proportional command signal to a solenoid control valve T7. This signal opens a control valve 28 and starts to fill the clutch 83 with hydraulic fluid. Next, this command is reduced from a lamp level during lamp time to a hold level till the clutch 83 is completely filled. A filling termination point is generated during hold time when clutch pressure becomes the lowest, and when a value that the average of cycle numbers of an instantaneous clutch slip is divided by a prescribed factor is larger than an instantaneous value of the clutch slip, a point during this time becomes a filling termination. |
