Abstract
본 발명은 차량의 주행속도 및 조향 토오크에 따라 유압 펌프의 공급 유량을 조절하는 동력 조향장치의 제어방법에 관한 것으로, 공급 유로의 유체 압력이 미리 설정된 최대 압력(PU) 이상인지를 판단하는 제1 과정과, 상기 제1과정에서 상기 유체 압력이 최대 압력(PU) 이하일 경우 상기 유체 압력이 미리 설정된 최저 압력(PL) 이상인지를 재 판단하는 제2 과정과, 상기 제2 과정에서 공급 유로의 유체 압력이 미리 설정된 최대 압력(PU) 이하면서 최저 압력(PL) 이상일 경우에는 모터(7)의 구동을 이전의 상태 그대로 유지하는 제3 과정과, 상기 제2 과정에서 상기 유체 압력이 미리 설정된 최저 압력(PL) 이하일 경우에는 차속을 판단하는 제4 과정과, 제4 과정에서 판단한 차속에 따라 미리 설정된 차속 그래프와 조향 핸들에 의한 조향 토오크의 값에 따라 공급 유량을 조절하는 제5 과정으로 제어되어, 차량을 주행속도에 따라 공급 유량을 조절하여 조향력을 가변시킴으로써 운전자는 차량의 주행속도에 따른 조향감으로 조향핸들을 조향하게 되고, 이로 인하여 조향 안정성을 향상시키게 되는 효과가 있다.The present invention relates to a control method of a power steering apparatus for adjusting a supply flow rate of a hydraulic pump according to a traveling speed and a steering torque of a vehicle, the method comprising: determining whether a fluid pressure of a supply flow path is greater than or equal to a preset maximum pressure (P U ). A second step of re-determining whether the fluid pressure is greater than or equal to a predetermined minimum pressure P L when the fluid pressure is equal to or less than the maximum pressure P U in the first step, and the second step; When the fluid pressure of the flow path is equal to or less than the preset maximum pressure P U and equal to or more than the minimum pressure P L , a third process of maintaining the driving of the motor 7 as it was, and the fluid pressure in the second process If this is less than a preset minimum pressure (P L) is depending on the value of the fourth step and the steering torque according to the fourth process of the vehicle speed and the steering wheel is previously set according to the graph determines the vehicle speed from the vehicle speed to determine the Controlled by the fifth process of controlling the supply flow rate, by adjusting the supply flow rate according to the traveling speed of the vehicle to change the steering force, the driver is steering the steering wheel with the steering feeling according to the driving speed of the vehicle, thereby improving the steering stability There is an effect to be improved.
