<P>PROBLEM TO BE SOLVED: To provide a hybrid vehicle drive control device that can suppress resonance of an internal combustion engine when stopping the internal combustion engine. <P>SOLUTION: The drive control device includes a planetary gear mechanism 16 in which the internal combustion engine 11 is connected to a carrier Ca through a first clutch C1, a first MG12 is connected to a sun gear Su, and a second MG13 is connected to a ring gear Ri, and a first MG12 is applied to a vehicle 1 connected with the internal combustion engine 11 through the second clutch C2. The drive control device, when changing the second clutch C2 into a release condition, while changing the first clutch C1 into an engagement condition and switching from a series parallel mode in which the internal combustion engine 11 and the second MG13 are used as driving sources to an EV drive mode in which the first clutch C1 is changed into the engagement condition and the internal combustion engine 11 is made to stopped and the second MG13 is made a driving source, the first clutch C1 is first changed to the release condition, then the second clutch C2 is changed to the engagement condition, and then the rotations speed of the internal combustion engine 11 is reduced by the first MG12, and the internal combustion engine 11 is stopped. <P>COPYRIGHT: (C)2012,JPO&INPIT |
