Abstract
Engagement of a clutch is at least partially controlled based upon the difference in rotational speed between the drive side of the clutch and the driven side of the clutch. As the rotational speed difference varies, the approach rate of the drive side and the driven side also varies for at least part of the total distance defined between the drive side and the driven side when the clutch is disengaged.
Claims19
A clutch connection control device for engagement and disengagement of a clutch, the engagement and disengagement being performed by a clutch actuator, the device comprising a clutch rotating speed difference detecting means that detects a difference in rotating speed between a drive side and a driven side of the clutch, clutch engagement speed varying means that varies a clutch engagement speed in proportion to variation in the clutch rotating speed difference detected by the clutch rotating speed difference detecting means, and clutch connecting means that causes the drive side and the driven side of the clutch to approach each other at the clutch engagement speed varied by the clutch engagement speed varying means.
A clutch engagement control method for engagement and disengagement of a clutch using a mechanical clutch actuator, the method comprising:
- detecting a clutch rotating speed difference, which is a difference between a rotating speed of a drive side of the clutch and a rotating speed of a driven side of the clutch,
- varying a clutch engagement speed in proportion to the detected clutch rotating speed difference, and
- moving the drive side and the driven side of the clutch toward each other at the varied clutch engagement speed.
