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 said clutch drive side and said detected turning speed of said clutch driven side; comparing means for comparing said turning speed difference with a specific value; 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 said turning speed difference becomes a specific value or less, and said control means controls clutch connection at a second speed higher than said first speed after said turning speed difference becomes said specific value or less; and a rate-of change detecting means for detecting a time-dependent rate of change of said detected turning speed difference, wherein said control means controls clutch connection at a third speed, higher than said first speed until the time-dependent rate of change of said detected turning speed difference becomes another specific value or less, and said control means controls clutch connection at said first speed after said time-dependent rate of change of said detected turning speed difference becomes said another specific value or less, said third speed for ending automatic speed change by returning said clutch release means to an initial position after said detected turning speed difference between said clutch drive side and said clutch driven side becomes zero.
