1. A control method for a series hybrid vehicle which includes a controller configured to perform control, and in which a drive wheel is driven by a travel motor using electric power of an electric power generation motor which is driven by power of an engine with a supercharger to generate the electric power, the control method comprising:
performing a pre-detection including determining whether overflow electric power is larger than system receivable electric power; and
subject to results of performing the pre-detection, performing fuel cut of the engine as the control if an excess amount of a torque over a drive engine torque of the electric power generation motor exceeds at least the drive engine torque of the electric power generation motor corresponding to the system receivable electric power indicating an electric power reception margin of a series hybrid system provided in the series hybrid vehicle, and the engine is supercharged.
