ABSTRACT:
The control device for the hybrid vehicle is mounted on the hybrid vehicle including the engine and the motor generator as the driving source and capable of switching at least two modes, i.e., the infinite variable speed mode and the fixed gear ratio mode. When the speed change is performed from the infinite variable speed mode to the fixed gear ratio mode, the first speed change control to maintain the number of revolutions equal to or larger than the number of engine revolutions at the time of setting the infinite variable speed mode and reduce the engine torque to shift the speed gear in the fixed gear ratio mode is executed. Thereby, when the speed change is performed from the infinite variable speed mode to the fixed gear ratio mode, it becomes possible to appropriately suppress the drivability deterioration caused due to the change of the number of engine revolutions.
