<P>PROBLEM TO BE SOLVED: To propose a transmission state changeover controller for a hybrid vehicle, greatly advantageous on cost and a space without needing to newly provide a second clutch, when simultaneously performing a speed change inside an automatic transmission and a mode changeover between an electric travel mode and a hybrid travel mode. <P>SOLUTION: An upshift from 4 to 5 for an automatic transmission 3 releases a direct clutch D/C from a fastening state, and is performed by a changeover of friction elements to fasten a front brake Fr/B from a release state, so that the direct clutch D/C that is a release side speed change friction element is used as the second clutch 7 (as shown Fig.3), causing slippage in time of the mode changeover; and it is not necessary to newly provide the second clutch 7, as shown in Fig.1 and Fig.2 (not shown). <P>COPYRIGHT: (C)2011,JPO&INPIT |
