The present invention relates to a control method of an electric vehicle. The present invention aims to provide the control method of an electric vehicle, wherein the electric vehicle without a multi-speed transmission can generate and implement shift feeling as in a vehicle having a multi-speed transmission. To achieve the purpose, according to the disclosed control method of the electric vehicle, a virtual shift model which uses vehicle driving information collected from the vehicle during driving as input is used to determine virtual shift intervention torque and torque limit by virtual shift stage from input variables and control a motor by using the determined virtual shift intervention torque and the torque limit by virtual shift stage, and motor torque command, so as to realize virtual multi-stage shift feeling.

    본 발명은 전기자동차의 제어 방법에 관한 것으로서, 다단 변속기가 부재한 전기자동차에서 다단 변속기가 장착된 차량에서와 같은 변속감을 생성 및 구현할 수 있는 전기자동차의 제어 방법을 제공하는데 주된 목적이 있는 것이다. 상기한 목적을 달성하기 위해, 주행 동안 차량에서 수집되는 차량 운전 정보를 입력으로 하는 가상 변속 모델을 통하여 입력 변수로부터 가상 변속 개입 토크 및 가상 변속단별 한계 토크를 결정하고, 상기 결정된 가상 변속 개입 토크 및 가상 변속단별 한계 토크와 모터 토크 지령을 이용하여 모터를 제어함으로써 가상의 다단 변속감을 구현하는 전기자동차의 제어 방법이 개시된다.
