Clutch control device
First Claim
1. 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:
- clutch control means for controlling a control amount of said clutch;
drive wheel rotation start detecting means for detecting a start of rotation of said drive wheel; and
control correction amount calculating means for calculating 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 calculating means calculates 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 calculating means calculates 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 means applies said control correction amounts to the control amount of said clutch to control said clutch.

Abstract
A clutch control device is provided 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. A clutch control unit is configured to control a control amount for said clutch. A drive wheel rotation start detector is configured to detect a start of rotation of said drive wheel. A control correction amount calculator is configured to calculate a control correction amount 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. The clutch control unit is further configured to apply said control correction amount to the control amount for said clutch to control said clutch.

17. 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. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
