Claims (2)
- 조향 토크, 조향각, 조향각속도, 차속을 입력받아 토크 부스트 제어, 복원력 제어, 댐핑 제어를 통해 모터의 목표 토크치를 계산하고, 현재 모터의 전류를 센싱한 다음 이에 대한 비례적분 제어(PI 제어)를 통해 상기 목표 토크치에 대해 과하거나 부족한 전압을 보상하는 PWM(Pulse Width Modulation) 신호를 발생시킴으로써 최종적인 모터 토크를 제어하는 전동식 파워 스티어링의 제어방법에 있어서,상기 비례적분 제어 단계에는 실시간으로 센싱되는 모터 속도에 따라 가변하는 비례상수(α)에 의한 모터 속응 제어가 추가된 것을 특징으로 하는 전동식 파워 스티어링의 제어방법.
- 청구항 1에 있어서,상기 비례상수(α)는 모터 속도에 반비례하는 값을 가지는 것을 특징으로 하는 전동식 파워 스티어링의 제어방법.
