摘要： The present invention provides a clutch connection method which controls the disconnection/connection of a wet friction clutch on the basis of a duty pulse outputted from an electronic control unit. When the clutch is connected, the electronic control unit initially outputs a start duty (Dst) for largely connecting the clutch as far as the vicinity of a torque point, and, thereafter, outputs, at prescribed time intervals (Δt), a gradual connection duty (Dk) for gradually connecting the clutch, and determines a gradual connection duty value on the basis of a clutch input/output side revolution difference ΔN. Since the clutch is gradually connected while monitoring the clutch connection state, variations between connection times and connection shock, resulting from individual clutch differences or the like, can be eliminated, whereby it is possible to achieve a stable feel. Further, in control which connects the clutch in sync with completion of a transmission gear shift, a plurality of clutch connection modes (an engine plus mode, an in-shaft plus mode, and a synchro mode) are preset, and the clutch connection modes are selected in accordance with the size of clutch input-side and output-side revolution numbers upon completion of a gear shift. Clutch connection is performed which conforms to actual conditions since a clutch connection mode is selected in accordance with the size of clutch input/output side revolution numbers rather than with respect to a shift-up or a shift-down.
