A control device for a vehicle comprises an electronic control unit which controls the rotational speed of an internal combustion engine to allow the rotational speed of the internal combustion engine to increase with an increase in a driving speed of a vehicle, performs a pseudo gear shift to control the rotational speed of the internal combustion engine to decrease the rotational speed of the internal combustion engine to a first rotational speed, performs a mechanical gear shift to change a second gear ratio according to a gear shift line determined by the driving speed and a value according to an acceleration request, and performs adjustment control to adjust the rotational speed of the internal combustion engine in advance in a period before performing the mechanical gear shift to match the rotational speed of the internal combustion engine with a pseudo gear shift threshold value when the mechanical gear shift is performed. 제어 장치는 (ⅰ) 상기 내연 기관의 상기 회전 속도가 상기 차량의 주행 속도의 증대와 함께 증대하도록 내연 기관의 회전 속도를 제어하고, (ⅱ) 상기 내연 기관의 상기 회전 속도가 제 1 회전 속도까지 감속하도록 상기 내연 기관의 상기 회전 속도를 제어하는 유사 변속을 실행하며, (ⅲ) 주행 속도와 상기 가속 요구에 따른 값에 의해 정해지는 변속선에 따라 제 2 기어비를 변경하는 기계 변속을 실행하고, (ⅳ) 상기 기계 변속을 실행하기 전의 기간에 있어서 상기 기계 변속이 행해지는 시점에 있어서의 상기 내연 기관의 상기 회전 속도가 상기 유사 변속 임계값에 일치하도록 상기 내연 기관의 상기 회전 속도를 미리 조정하는 조정 제어를 실행하도록 구성되는 전자 제어 유닛을 포함한다.
