Clutch control device

A clutch control device for a clutch to connect and disconnect the transmission of a rotational drive force from a power source to a drive wheel in a vehicle, said clutch control device comprising:

• a clutch control unit configured to control a control amount for said clutch;
• a drive wheel rotation start detector configured to detect a start of rotation of said drive wheel;
• and
• a control correction amount calculator configured to calculate two control correction amounts of said clutch based on a difference between the clutch control amount detected at the start of rotation of said drive wheel and a predetermined reference value,
• wherein said control correction amount calculator is further configured to calculate a first control correction amount of the two control correction amounts to be applied to clutch control during running of said vehicle,
• wherein said control correction amount calculator is further configured to calculate a second control correction amount of the two control correction amounts to be applied to a reduction control of an invalid stroke at starting of said vehicle, wherein the invalid stroke is an amount of a movement of a plurality of clutch plates of the clutch from an initial position to an operational position where the plurality of clutch plates come into contact with each other,
• wherein said clutch control unit is further configured to apply said control correction amounts to the control amount for said clutch to control said clutch.

A clutch control method for connecting and disconnecting the transmission of a rotational drive force from a power source to a drive wheel in a vehicle, said clutch control method comprising:

• controlling, by a clutch control unit, a control amount for said clutch;
• detecting, by a drive wheel rotation start detector, a start of rotation of said drive wheel;
• calculating, by a control correction amount calculator, two control correction amounts for said clutch based on a difference between the clutch control amount detected at the start of rotation of said drive wheel and a predetermined reference value;
• calculating, by said control correction amount calculator, a first control correction amount of the two control correction amounts to be applied to clutch control during running of said vehicle;
• calculating, by said control correction amount calculator, a second control correction amount of the two control correction amounts to be applied to a reduction control of an invalid stroke at starting of said vehicle, wherein the invalid stroke is an amount of a movement of a plurality of clutch plates of the clutch from an initial position to an operational position where the plurality of clutch plates come into contact with each other;
• and
• applying, by said clutch control unit, said control correction amounts to the control amount of said clutch to control said clutch.
