<p><P>PROBLEM TO BE SOLVED: To provide a shift controller of an on-vehicle power unit capable of connecting a shift clutch by always proper setting in each shift operation. <P>SOLUTION: The shift controller 2 of the on-vehicle power unit 1 in which power of an internal combustion engine E is output through a multistage transmission M having the wet-type shift clutch C and a plurality of speed changing stages has a combustion control unit 41, a clutch actuation mechanism 24, a clutch actuation condition detecting unit, a shift command unit, clutch input and output rotating speed difference detecting units 53, 54, and a shift controlling unit 40. The shift controlling unit 40 derives a dragging degree G of the shift clutch from a clutch input and output rotating speed differenceΔCn. The shift controller 2 of the on-vehicle power unit 1 regards the dragging degree G as a parameter to determine an actuator driving command amount R, and drives an actuator 34 on the basis of the actuator driving command amount R to control engagement of the shift clutch. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
