하이브리드 차량의 제어 방법은, 엔진의 동력을 사용하여 배터리를 충전 가능한 발전기와, 배터리의 전력에 의해 구동륜을 구동시키는 전동 모터를 구비하는 하이브리드 차량의 제어 방법이다. 제어 방법은, 배터리의 충전량이 제1 충전 역치까지 저하되었을 때, 엔진을 제1 회전 속도로 구동시키고, 엔진이 제1 회전 속도로 구동하고 있으며, 또한 충전량이 제1 충전 역치보다 작은 제2 충전 역치까지 저하되었을 때는, 엔진을 제1 회전 속도보다 큰 제2 회전 속도로의 구동으로 전환하고, 충전량이 제1 충전 역치보다 큰 충전 종료 역치 이상으로 될 때까지 엔진의 구동을 계속시킨다. A control method for a hybrid vehicle related to the present invention, the control method for a hybrid vehicle control method for a hybrid vehicle including a generator and an electric motor, the generator being configured to charge a battery by use of power of an engine, the electric motor being configured to drive driving wheels by electric power of the battery. The control method having driving the engine at a first rotation speed when a charging amount of the battery decreases to a first charging threshold; changing the engine to driving at a second rotation speed larger than the first rotation speed when the engine is driven at the first rotation speed and the charging amount decreases to a second charging threshold smaller than the first charging threshold; and continuing driving of the engine until the charging amount becomes equal to or more than a charging end threshold larger than the first charging threshold.
