According to the present invention, a control method of an electronic continuously variable transmission (ECVT) applied hybrid vehicle comprises the following steps of: detecting whether downshifting is requested by operation of a virtual gear shifting map or a paddle shift by a control unit; calculating a virtual engine speed based on a preset virtual gear ratio in accordance with a vehicle speed and a target gear shifting stage by the control unit when detecting that downshifting is requested as a result of performing the detection step; comparing the calculated virtual engine speed and an actual engine speed by the control unit after the calculation step; and driving a motor generator to generate virtual drag torque set in accordance with the virtual engine speed by the control unit when the virtual engine speed is faster than the actual engine speed as a result of performing the comparison step. Therefore, a gear shifting feeling can be maximized.

    본 발명에 따른 무단변속기가 적용된 하이브리드 차량의 제어방법은 제어부가 가상변속맵 또는 패들시프트 조작에 의해 다운시프트가 요청되는지 감지하는 단계; 감지단계 수행결과, 다운시프트 요청이 감지될 경우, 제어부가 차속 및 목표변속단에 따라 기설정된 가상기어비를 기반으로 하여 가상엔진속도를 산출하는 단계; 산출단계 후, 제어부가 산출된 가상엔진속도와 실제엔진속도를 비교하는 단계; 및 비교단계 수행결과, 가상엔진속도가 실제엔진속도보다 클 경우, 제어부가 가상엔진속도에 따라 설정된 가상드래그토크를 발생시키도록 모터제너레이터를 구동시키는 단계;를 포함할 수 있다.
