Abstract
A controller controls a hybrid vehicle that has an internal combustion engine and an electric motor that assists the engine. In fuel cut control during vehicle deceleration, the controller sets a return engine speed at a value that inevitably stalls the engine. However, the motor executes power assist-control so that engine speed is maintained, engine stall does not occur, and the engine speed smoothly converges at an idle speed. Thus, the engine speed is set at a lower value, so that fuel cut is executed for as long as possible.
