1. An engine start control device, comprising:
a power transmission system including at least an engine provided with a motor for driving and a clutch to be hydraulically controlled; a mechanical oil pump provided on the power transmission system, for supplying a hydraulic pressure for hydraulic control; an electric oil pump connected in parallel to the mechanical oil pump to be independently driven; hydraulic pressure detection means for detecting the hydraulic pressure for the hydraulic control; idling stop control configured to, with a predetermined idling stop condition satisfied, stop the engine, and with a predetermined restart condition and a predetermined fuel injection condition satisfied, start the engine; electric oil pump control means for driving the electric oil pump, with the hydraulic pressure detected by the hydraulic pressure detection being less than a first predetermined pressure during a time period in which the engine is stopped in a case of idling stop; and motor control means for driving the motor so that a rotation speed of the motor becomes identical with a calculated target rotation speed, wherein, after the idling stop, with the predetermined restart condition satisfied, the motor control means sets the amount of change in the calculated target rotation speed to a first predetermined value, with the hydraulic pressure being greater than or equal to a second predetermined pressure, wherein, after the idling stop, with the predetermined restart condition satisfied, the motor control means sets the amount of change in the calculated target rotation speed to a second predetermined value with the hydraulic pressure being less than the second predetermined pressure, and wherein the first predetermined value is greater than the second predetermined value. |
