ELECTRIFIED VEHICLE AND CONTROL METHOD FOR ELECTRIFIED VEHICLE

An electrified vehicle includes an electric power storage device, a drive device, a sensor, and an electronic control unit. The electronic control unit causes transition of a traveling mode to an FS mode when a FS traveling condition is established. The electronic control unit detects a sign of an abnormality of an assembled battery using a detection value of a sensor when a sensor unit is normal. When the FS traveling condition is established and the sign of the abnormality of the assembled battery is not detected, the electronic control unit sets the FS mode to a predetermined first FS mode. When the FS traveling condition is established and the sign of the abnormality of the assembled battery is detected, the electronic control unit sets the FS mode to a second FS mode different from the predetermined first FS mode.
