본 발명은 모터 감속비 차이를 이용한 전기자동차의 제어장치 및 그 방법에 관한 것으로, 주행모드에 대한 데이터를 입력하는 입력부. 주행 속도를 감지하는 센서, 및 상기 주행모드에 따라 속도구간을 상이하게 설정하고, 제 1 감속기에 대한 제 1 클러치의 연결 및 전륜모터의 구동을 제어하고, 제 2 감속기에 대한 제 2 클러치의 연결 및 후륜모터의 구동을 제어하며, 상기 주행 속도에 대응하는 속도구간을 판단하여 차량이 전륜구동, 4륜구동 및 후륜구동 중 어느 하나로 동작하도록 제어하는 프로세서를 포함하고, 전륜과 후륜의 상이한 감속비를 기반으로 클러치 모터의 구동을 상이하게 제어하여 전비 효율을 개선하고 차량 주행 성능 및 안정성을 향상시킬 수 있다.

    Provided are an electric vehicle control device and method using the difference in the motor reduction ratio. An input part inputs data regarding driving mode. A sensor detects a driving speed. A processor sets different speed ranges according to the driving mode, controls engagement of a first clutch with respect to a first reducer and operation of a front wheel motor, controls engagement of a second clutch with respect to a second reducer and operation of a rear wheel motor, determines a speed range among the speed ranges corresponding to the driving speed, and controls an electric vehicle to operate in one of front-wheel drive, four-wheel drive, and rear-wheel drive. The clutch and motor driving is controlled variously on the basis of the difference in the reduction ratio of the front wheel and the rear wheel, thereby improving fuel efficiency and improving the driving performance and stability of the electric vehicle.
