    Abstract: PROBLEM TO BE SOLVED: To provide a vehicle and a method for controlling the vehicle, suppressing an unpleasant feeling imparted to an occupant when an engine stops. SOLUTION: When performing a changeover to a clutch C1, C2 non-transmission state, a controller 50 synchronously controls a driving device 11 such that a difference between driving shaft 22 side rotation and driving device 11 side rotation of clutches C1, C2 becomes a prescribed value or below based on output of a rotation sensor 76. When stop conditions of the engine 8 are satisfied when controlling the clutches C1, C2 in the non-transmission state, the controller 50 stops the engine 8, and successively performs the synchronous control until the engine 8 stops. Preferably, the stop conditions include that output of a first rotation sensor 77 or 78 shows a rotation speed wherein an electric motor MG1 has an overspeed when the clutch C1 or C2 is connected.
