하이브리드 차량(1)을 주행 구동시키는 전동기(13)와, 상기 전동기에 전력을 공급하는 발전기(12)와, 상기 발전기를 구동하는 엔진(11)을 구비하는 하이브리드 차량의 제어 방법에 있어서, 상기 차량에 대한 목표 구동력(Fd)의 변화량 또는 변화의 배율을 연산하고, 상기 목표 구동력의 변화량 또는 변화의 배율에 따라서, 상기 엔진의 회전 속도의 변화율(NRu, NRd)을 설정하고, 상기 엔진의 회전 속도의 변화율에 기초하여, 상기 엔진의 회전 속도를 제어한다. A method for controlling a hybrid vehicle (1) is provided. The hybrid vehicle includes an electric motor (13) that drives the vehicle to travel, a generator (12) that supplies power to the electric motor, and an engine (11) that drives the generator. The method includes calculating an amount or factor of change in target driving force (Fd) for the vehicle, setting a change rate (NRu, NRd) of a rotational speed of the engine in accordance with the amount or factor of change in the target driving force, and controlling the rotational speed of the engine on the basis of the change rate of the rotational speed of the engine.
