Abstract
To provide a clutch connection control system capable of shortening the time required for clutch connection, preventing the degradation of riding comfort upon clutch connection, and ensuring good operability. A separation distance, that is, a shift amount of a clutch driven side from a clutch drive side is controlled by a clutch release mechanism driven by a drive motor. A drive side turning speed detecting portion detects a turning speed Nin of the drive side. A driven side turning speed detecting portion detects a turning speed Nout of the driven side. A turning speed difference detecting portion detects a difference Nd between the detected drive side turning speed Nin and driven side turning speed Nout. A rate-of-change detecting portion detects a time-dependent rate of change &Dgr;Nd of the detected turning speed difference Nd. A control portion performs clutch connection at a first speed until the time-dependent rate of change &Dgr;Nd becomes a specific value or less and performs clutch connection at a second speed lower than the first speed after the time-dependent rate of change &Dgr;Nd becomes the specific value or less.
