Abstract
A control device for restarting an engine is configured to engage a forward clutch of an automatic transmission quickly, with little shock and without involving a special cost for restarting the engine. When the engine is restarted, a way for supplying an oil is changed in accordance with a leaving amount of an oil from an oil passage with respect to the forward clutch of the automatic transmission or an oil temperature. A time for executing a quick pressure increase control and a control target pressure is changed in accordance with a leaving amount of the oil or the oil temperature. Further, the quick pressure increase control is started at a timing when an engine revolution (a rotational speed of an oil pump) is equal to or greater than a predetermined value.
