Clutch system

A clutch system comprising:

• a clutch that i) includes a clutch disc that is movable in a rotation axis direction of a flywheel connected to a power unit, and ii) is brought into an engaged state, in which the clutch disc and the flywheel come into contact with each other, as the clutch disc, when supplied with hydraulic oil, moves toward the flywheel at a speed corresponding to an amount of the hydraulic oil;
• a control valve that supplies to the clutch an amount of the hydraulic oil corresponding to a current value of current supplied from a power source;
• and
• a supply control part, when transitioning the clutch from a disengaged state, in which the clutch disc and the flywheel are not in contact with each other, to the engaged state, that i) supplies the current at a first current value to the control valve, ii) sets the current value of the current supplied to the control valve to a second current that is value smaller than the first current value, after supplying the current at the first current value to the control valve, and iii) after setting the current value of the current to the second current value, decreases the current value of the current over time so that the current value of the current reaches a third current value smaller than the second current value at a timing when the clutch in the disengaged state is brought into the engaged state.
