Abstract:
A clutch connection control system comprising:clutch release means for disconnecting and connecting a clutch drive side from a clutch driven side by turning an electric motor; drive side turning speed detecting means for detecting a turning speed of the clutch drive side; driven side turning speed detecting means for detecting a turning speed of the clutch driven side; turning speed difference detecting means for detecting a difference between said detected turning speed of the clutch drive side and said detected turning speed of the clutch driven side; rate-of-change detecting means for detecting a time-dependent rate of change of said detected turning speed difference; and control means for controlling said clutch release means to disconnect and connect the clutch drive side from the clutch driven side, on the basis of said detected turning speed difference, and said control means controls clutch connection at a first speed until the time-dependent rate of change of said detected turning speed difference becomes a specific value or less, and said control means controls clutch connection at a second speed lower than said first speed after the time-dependent rate of change of said detected turning speed difference becomes said specific value or less.
