<P>PROBLEM TO BE SOLVED: To provide a control device for a hybrid vehicle stabilizing behavior of the vehicle when switching from an EV drive to an engine drive and shortening its transition time. <P>SOLUTION: The control device ECU of the hybrid vehicle is configured to control engagement of a designated engagement element C1 after an input rotation speed at an engine ENG side and output rotation speed at an output shaft 40 side coincides with each other in the designated engagement element C1 in transition from a driving state using a drive motor M1 to a driving state using an engine ENG. The control device supplies engagement standby pressure, which does not cause engagement, to the designated engagement element C1 before coincidence between the input rotation speed and output rotation speed in the designated engagement element C1, and controls to determine whether or not a hydraulic pressure supply device 7 fails by detecting the hydraulic pressure supplied to a plurality of engagement elements C1 to C5, and CL. <P>COPYRIGHT: (C)2008,JPO&INPIT |
