Abstract:
1. A clutch control device that performs slip control by hydraulically controlling an engagement state of a clutch provided between an output shaft of an engine and an input shaft of an automatic speed change mechanism based on an oil pressure command value, the clutch control device comprising: an actual rotational speed difference detecting unit that detects an actual rotational speed difference between a rotational speed of the output shaft of the engine and a rotational speed of the input shaft of the automatic speed change mechanism; a target rotational speed difference setting unit that sets a target rotational speed difference between the rotational speed of the output shaft of the engine and the rotational speed of the input shaft of the automatic speed change mechanism; a feedback value calculating unit that calculates a feedback oil pressure value from a deviation between the actual rotational speed difference and the target rotational speed difference; a deviation out-of-range determining unit that determines whether the deviation between the actual rotational speed difference and the target rotational speed difference is out of a predetermined range; a feedback value correcting unit that, when the deviation out-of-range determining unit determines that the deviation is out of the predetermined range, sets a correction value and corrects the feedback oil pressure value by the correction value, wherein the feedback value correcting unit sets the correction value to a higher value as the rotational speed of the input shaft of the automatic speed change mechanism becomes higher; and an oil pressure command unit that generates the oil pressure command value based on the feedback oil pressure value corrected by the correction value.
