ABSTRACT:
A clutch control unit includes a clutch learning unit (4b) for determining a clutch connection characteristic (M) based on the clutch position at which the number of revolutions of an output shaft of the clutch reaches a predetermined value when the clutch is moved toward connection from a predetermined learning starting point and a clutch off detector (4c) for determining a clutch off point at which the number of revolutions of the output shaft is zero by moving the clutch toward disconnection and taking as a new learning starting point the clutch off point or a point made by adding a small offset value to the clutch off point, thereby controlling the clutch based on the clutch connection characteristic (M).
