Patent ID: 7881847

Claim:
An automatic clutch device comprising: a clutch control device; an automatic wet multiple plate friction clutch interposed between a driving-side power transmission mechanism and a driven-side power transmission mechanism; and an electric actuator arranged to engage and disengage the automatic wet multiple plate friction clutch directly or indirectly; wherein the clutch control device includes: a driving-side rotational speed detection device configured to detect a driving-side rotational speed, which is a rotational speed of a driving part of the automatic wet multiple plate friction clutch or the driving-side power transmission mechanism; a clutch position detection device configured to detect a position of the automatic wet multiple plate friction clutch; a storage device configured to store a target position of the automatic wet multiple plate friction clutch set in association with the driving-side rotational speed; a drive control unit configured to receive a detected value of the driving-side rotational speed from the driving-side rotational speed detection device and to perform drive control of the automatic wet multiple plate friction clutch based on the target position of the automatic wet multiple plate friction clutch corresponding to the detected value stored in the storage device and the detected position of the automatic wet multiple plate friction clutch; and a clutch position change device configured to change the target position according to human manipulation.
