Driving control device of vehicle

A driving control device of a vehicle, comprising:

• an automatic transmission that transmits a driving force of an engine to a wheel by engaging a frictional engagement element, comprising:
• a hydraulic control device which hydraulically controls an engagement of the frictional engagement element;
• a mechanical oil pump which is driven by the engine and supplies hydraulic pressure to said hydraulic control device, and
• an electric oil pump which supplies hydraulic pressure to said hydraulic control device;
• and
• a motor connected to said mechanical oil pump and transmitting the driving force to the automatic transmission, wherein said electric oil pump supplies oil to said hydraulic control device at an engine automatic stopping control time at which the driving of the engine is automatically stopped after the vehicle stops and a predetermined condition is established and said motor is driven so that said mechanical oil pump supplies the oil to said hydraulic control device during said engine automatic stopping control at a time when said electric oil pump can not be driven.
