차량 제어 방법은, 내연 기관(1)이 정지된 상태에 있어서, 제2 전동(6)기에 요구되는 구동력이 증가된 경우, 배터리(5)가 공급하는 전력에 의해 제2 전동기(6)가 출력하는 구동력을, 배터리(5)가 전동 차량을 구동시키기 위해 공급 가능한 전력으로부터 정해지는 최대 구동력보다 낮게 제한한다. 그리고, 낮게 제한된 구동력을 제2 전동기(6)가 출력하고부터, 내연 기관(1)이 시동되어 제1 전동기(4)가 발전을 시작하기까지의 동안, 배터리(5)가 공급하는 전력에 의해 제2 전동기(6)가 출력하는 구동력을, 시간의 경과에 따라 증가시킨다. In a vehicle control method, when drive force which a second electric motor 6 is requested to output increases in a state where an internal combustion engine 1 is stopped, drive force which the second electric motor 6 outputs by using electric power supplied by a battery 5 is limited to a lower level than maximum drive force determined from electric power which can be supplied by the battery 5 to drive an electric-powered vehicle. Then, the drive force which the second electric motor 6 outputs by using the electric power supplied by the battery 5 is increased over time in a period from when the second electric motor 6 outputs the drive force limited to the lower level to when the internal combustion engine 1 is fired up and a first electric motor 4 starts power generation.
