To prevent a continuous teeth striking noise generated in a gear train when an engine is in a rotating state.The engine (1) and a second motor/generator (3) are directly connected via a gear train (46) comprising a plurality of gears (46a, 46b, 46c) that are engaged with each other. In this control method for a series hybrid vehicle, when the engine (1) is in the rotating state a prescribed torque is continuously applied to the second motor/generator (3) such that a transmission torque of the gear train (46) does not continuously fluctuate above and below zero torque. The prescribed torque continuously applied to the second motor/generator (3) is a negative torque value during a power generation operation in which the second motor/generator (3) is rotated by the engine (1) and is a positive torque value during a motoring operation in which the engine (1) is rotated by the second motor/generator (3).
