A control device for a hybrid vehicle, wherein when starting an engine using a first battery, if the residual capacity of the first battery is not enough to start the engine because of the reduced-voltage of the first battery, the engine is started by driving an ACG starter supplied with electricity from a second battery having a voltage rated value different from that of the first battery.

Hybrid vehicle control device

An engine start control system is provided that includes a controller configured to perform an idle stop control to stop an engine based on an establishment of a condition. The system further includes a motor configured to reverse-rotationally drive a crankshaft to a predetermined position for normal-rotational or reverse-rotational driving, after engine stop. The controller includes a reverse-rotational drive controller configured to reverse-rotationally drive the motor at a rewinding control duty ratio immediately after the engine is stopped. The controller further includes a reverse-rotation stop condition processor configured to detect whether the crankshaft is rewound to the predetermined position by the reverse-rotational drive controller. Further, the controller includes a motor brake controller configured to apply a brake to the crankshaft by reverse-rotationally driving the motor when it is detected that the crankshaft is rewound to the predetermined position. The motor brake controller is configured to apply the brake stepwise.
