Provided is a hybrid vehicle in which a motor/generator (5) is positioned between an engine (1) and an automatic transmission (3), the engine (1) and the motor/generator (5) are connected via a first clutch (6), and a second clutch (7) is provided between the motor/generator (5) and a drive wheel (2). In an HEV mode in which the first clutch (6) is engaged, when deceleration of a vehicle is determined to be rapid deceleration of a threshold value or greater, the first clutch (6) is released and at the same time fuel supply to the engine (1) is stopped via an engine controller (21). When rapidly decelerating, even when the number of engine revolutions (Ne) drops to an idling rotation or lower due to a delay in the release of the first clutch (6), there is no combustion or explosion and thus floor vibration does not occur.
