CLUTCH SYSTEM

Abstract

Coupling system (S), comprising: a clutch (110) comprising i) a clutch disc (112) movable in a direction of rotation of a flywheel (111) connected to a drive unit (100), and ii) being brought into an engaged state in which the clutch disc (112) and the flywheel (111) come into contact with each other when the clutch disc (112), when supplied with hydraulic oil (121), moves in the direction of the flywheel (111) at a speed corresponding to a quantity of the hydraulic oil (121); a control valve (120) that supplies the clutch (110) with a quantity of hydraulic oil (121) corresponding to a current value of the current supplied by a power source (130); and a supply control unit (222) which, when the clutch (110) transitions from a disengaged state, in which the clutch disc (112) and the flywheel (111) are not in contact with each other, to the engaged state, i) supplies the current with a first current value to the control valve (120), ii) sets the current value of the current supplied to the control valve (120) to a second current whose value is less than the first current value, after the current with the first current value has been supplied to the control valve (120), and iii) after setting the current value to the second current value, decreases the current value over time, so that at the time when the clutch (110) is brought from the disengaged state to the engaged state, the current value reaches a third current value which is less than the second current value.
