Abstract

In a drive control device, a controller automatically stops an engine if an execution condition of an idling stop is satisfied, and an electric oil pump is driven during an automatic stop of the engine. A first friction engaging element establishes a starting gear position and a second friction engaging element is released when a vehicle starts. A second solenoid drains oil to be supplied to the second friction engaging element according to an indicator current. A drain degree becomes smaller by reducing the indicator current. The controller reduces the indicator current below a minimum value during the automatic stop of the engine.
