Clutch control device

A clutch control apparatus for a clutch, which connects and disconnects a rotational driving force transmitted to a drive wheel from a power source of a vehicle, the clutch includes an input side rotating body and an output side rotating body which synchronously rotate with the clutch being connected, the clutch control apparatus comprising:

• an input side rotational speed detector configured to detect a rotational speed of the input side rotating body;
• an output side rotational speed detector configured to detect a rotational speed of the output side rotating body;
• a clutch control unit configured to control a control amount of the clutch;
• a brake configured to temporarily stop the output side rotating body while the clutch is disconnected;
• a clutch-control-amount detector configured to detect the control amount of the clutch;
• an engagement start detector configured to detect an engagement start of the clutch when a rotational speed difference between the input side rotating body and the output side rotating body becomes equal to or less than a predetermined value;
• an engagement-start control-amount detector configured to detect the control amount of the clutch in the engagement start;
• and
• a clutch-correction-control-amount deriver configured to derive a correction control amount of the clutch based on the control amount of the clutch at the time when the engagement start is detected after the output side rotating body is temporarily stopped,
• wherein the clutch control unit feedback-controls the control amount of the clutch based on the correction control amount.

A clutch control method for a clutch, which connects and disconnects a rotational driving force transmitted to a drive wheel from a power source of a vehicle, the clutch includes an input side rotating body and an output side rotating body which synchronously rotate with the clutch being connected, the clutch control method comprising:

• detecting, at an input side rotational speed detector, a rotational speed of the input side rotating body;
• detecting, at an output side rotational speed detector, a rotational speed of the output side rotating body;
• controlling, by a clutch control unit, a control amount of the clutch;
• temporarily stopping, using a brake, the output side rotating body while the clutch is disconnected;
• detecting, at a clutch-control-amount detector, the control amount of the clutch;
• detecting, at an engagement start detector, an engagement start of the clutch when a rotational speed difference between the input side rotating body and the output side rotating body becomes equal to or less than a predetermined value;
• detecting, at an engagement-start control-amount detector, the control amount of the clutch in the engagement start;
• deriving, at a clutch-correction-control-amount deriver, a correction control amount of the clutch based on the control amount of the clutch at the time when the engagement start is detected after the output side rotating body is temporarily stopped;
• and
• feedback-controlling, at the clutch control unit, the control amount of the clutch based on the correction control amount.
