The present invention relates to a control method of an electric vehicle. A main objective of the present invention is to provide a control apparatus for generating a virtual shift feeling of the electric vehicle which can directly freely change and adjust variables related to virtual shift feeling so that a driver can receive the virtual shift feeling that he or she prefers, and the method therefor. For achieving the above purpose, in order to simulate multi-step shifting feeling which the driver could feel when shifting a multi-speed transmission vehicle while driving in the electric vehicle without a multi-speed transmission, disclosed is the control method for generating the virtual shift feeling according to a driver driving input value and a vehicle status based on a virtual shift feeling generation related variable value preset by the driver. The control method of the electric vehicle of the present invention comprises the following steps of: determining a basic torque command in real time; determining a virtual target shift stage; selecting a virtual shift intervention torque profile; generating a final motor torque command; and controlling an operation of a motor.
본 발명은 전기자동차의 제어 방법에 관한 것으로서, 운전자가 자신이 선호하는 가상 변속감을 제공받을 수 있도록 가상 변속감 생성 관련 변수들을 직접 자유롭게 변경 및 조정할 수 있는 전기자동차의 가상 변속감 생성을 위한 제어 장치 및 방법을 제공하는데 주된 목적이 있는 것이다. 상기한 목적을 달성하기 위해, 다단 변속기가 부재한 전기자동차에서 주행 동안 다단 변속기 차량의 변속시 운전자가 느낄 수 있었던 다단 변속감을 모사할 수 있도록 운전자에 의해 미리 설정된 가상 변속감 생성 관련 변수값을 기초로 운전자 운전 입력값 및 차량 상태에 따른 가상 변속감을 생성하는 제어 방법이 개시된다.
