CLUTCH SYSTEM

A clutch system includes a clutch in which a clutch disc and a flywheel come into contact with each other, a control valve that supplies hydraulic oil to the clutch, and a supply control part that supplies electricity from a power source to the control valve. The supply control part supplies current at a first current value A to the control valve, then sets a current value of the current to a second current value A that is smaller than the first current value A, and after setting the current value to the second current value A, decreases the current value over time so that the current value reaches a third current value A that is smaller than the second current value A at a timing when the disengaged clutch is brought into an engaged state.
