<P>PROBLEM TO BE SOLVED: To provide a control device of a hybrid vehicle drive system which control device simultaneously and parallely controls a clutch engaging action and a down-shift speed-changing action, thereby finishes these two actions faster than a conventional case to enable the quick start of acceleration of a vehicle. <P>SOLUTION: The control device includes means (t21 to t26) which, when a clutch engaging instruction Cc and a down-shift speed-changing determination Ds arise in sequence within a priority determination time period Tf, simultaneously and parallely controls these two actions to bring an engine revolution Ne equal to a next-shift stage input shaft revolution Ni2, a means (t24) which sends out the clutch engaging instruction, means which make clutch engagement (t24 and t25 reduce a clutch pressure Pc), means which release a release-side frictional engagement element (t5 to t23 reduce a release pressure PA), means (t23 to t26) which perform control to bring a motor revolution Nm equal to the next-shift stage input shaft revolution Ni2, and means which make engagement of an engagement-side frictional engagement element (t26 and t27 raise an engagement pressure PB). <P>COPYRIGHT: (C)2013,JPO&INPIT |
