    • PROBLEM TO BE SOLVED: To improve learning accuracy of stroke finish hydraulic pressure. SOLUTION: This clutch control device controls a clutch by driving a piston by a working fluid, and is characterized by having a stroke starting determining means S1 detecting stroke starting hydraulic pressure at this time by determining that the piston starts a stroke, a stroke finish determining means S4 detecting the stroke finish hydraulic pressure at this time by determining that the piston finishes the stroke, a stroke finish range estimating means S3 estimating a range of the stroke finish hydraulic pressure from the stroke starting hydraulic pressure detected by the stroke starting determining means, and learning means S5 and S6 learning the stroke finish hydraulic pressure detected by the stroke finish determining means when the stroke finish hydraulic pressure falls within the range of the stroke finish hydraulic pressure.
