Abstract
Variator () and forward clutch (Fwd/C) disposed in series are provided between engine () having starter motor () and driving wheel (). Sailing stop control that, on the basis of satisfaction of sailing entering condition, interrupts power transmission by frictional engagement element (Fwd/C), stops engine () and performs coast-travel is performed. When sailing entering condition is satisfied, coast-travel is started with rotation stop timing of variator () being delayed with respect to rotation stop timing of engine (). When accelerator pedal depression operation intervenes after start of coast-travel, engine () is restarted by starter motor (). When judged that input and output rotation speeds of frictional engagement element (Fwd/C) become synchronization rotation speed after restart of engine (), frictional engagement element (Fwd/C) is reengaged. Shift response from coast-travel to normal travel is therefore improved at change-of-mind at which sailing quitting condition is satisfied during progress of automatic stop of engine.
