Abstract

본 발명은 운전자가 액셀 페달과 브레이크 페달을 작동하지 않는 경우에도 차속에 따라 구동모터를 제어하여 오르막 길에서 정차중 재출발시 주차 브레이크의 조작없이도 차량이 뒤로 밀리는 것을 방지함으로 운전자의 조작을 용이하게 하기 위한 것으로, 엑셀 페달이 작동되면 엑셀 페달의 밟아진 정도(A)에 따라 구동모터의 출력토오크(T0)가 양(+)의 방향으로 증가되도록(T0=f1(A)), 브레이크 페달이 작동되면 차속(V)에 따라 구동모터의 출력토오크(T0)가 음(-)의 방향으로 증가되도록 (T0=f2(V)) 구동모터를 제어하는 전기자동차의 모터제어방법에 있어서, 엑셀 페달과 브레이크 페달이 모두 작동되지 않은 경우, 차속(V)이 일정속도(V1) 이하이면 (V≤V1) 구동모터의 출력토오크(T0)가 소정의 토오크(T1)로 유지되도록 구동모터를 제어하는 저속시 제어단계(S10)와, 차속이 일정속도 보다 크면(VV1) 차속에 따라 구동모터의 출력 토오크가 음(-)의방향으로 증가되도록(T0=f2'(V)) 구동모터를 제어하는 고속시 제어단계(S20)로 구성되는 것을 특징으로 하는 오르막 길에서의 출발을 용이하게 하기 위한 전기자동차의 모터제어방법이다.The present invention controls the driving motor according to the speed of the vehicle even when the driver does not operate the accelerator pedal and the brake pedal to prevent the vehicle from being pushed back without the operation of the parking brake when starting again on the way up to facilitate the operation of the driver. When the accelerator pedal is operated, the brake pedal is operated so that the output torque T0 of the drive motor is increased in the positive direction (T0 = f1 (A)) according to the stepped amount (A) of the accelerator pedal. In the motor control method of the electric vehicle to control the drive motor so that the output torque (T0) of the drive motor increases in the negative (-) direction according to the vehicle speed (V), When the brake pedals are not operated at all, when the vehicle speed V is less than or equal to the constant speed V1, the low speed for controlling the drive motor to maintain the output torque T0 of the drive motor at a predetermined torque T1. Time control step (S10), When the vehicle speed is greater than the predetermined speed (VV1), the output torque of the driving motor increases in the negative (-) direction according to the vehicle speed (T0 = f2 '(V)). The motor control method of the electric vehicle for facilitating the departure from the uphill road characterized in that.
