Abstract:
In this drive control device, when a condition for executing an idle stop is satisfied a controller automatically stops the engine, and an electric oil pump is driven during the automatic stoppage of the engine. A first friction engagement element establishes a forward gear stage, and a second friction engagement element is disengaged when forward movement begins. In accordance with an indicated current a second solenoid drains oil supplied to the second friction engagement element. The degree of draining decreases as the indicated current decreases. The controller changes the indicated current so as to be lower than a minimum value during the automatic stoppage of the engine.
