This vehicle (1) constitutes a tandem hybrid vehicle in which drive wheels (6) are driven by a travel motor (4) using the electric power of a power generation motor (3) that is driven by the power of an internal combustion engine (2) provided with a turbocharger (7) and generates power. A control method of a vehicle (1) includes performing a fuel cut of an internal combustion engine (2) in a case where an overflow electric power (EPOVER) is at least higher than a system input electric power (EPSYS) and the internal combustion engine (2) is boosted. 本发明的车辆(1)构成利用由设置有涡轮增压器(7)的内燃机(2)的动力驱动而发电的发电用电动机(3)的电力，由行驶用电动机(4)对驱动轮(6)进行驱动的串联式混合动力车辆。车辆(1)的控制方法包括：在溢出电力(EP_OVER)至少高于系统可输入电力(EP_SYS)、且内燃机(2)被增压的情况下，进行内燃机(2)的燃料切断。
