Abstract

본 발명은 차량의 주행속도 및 조타 토오크에 따라 모터의 구동력을 조절하여 차량의 주행속도에 적합한 조향감을 느낄 수 있도록 하는 것이다.The present invention is to adjust the driving force of the motor according to the running speed and steering torque of the vehicle to feel the steering feeling suitable for the running speed of the vehicle.

본 발명은 조향 토오크가 미리 설정된 값 이하일 경우에 유체의 압력이 미리 설정된 압력 상한값 및 압력 하한값의 사이를 유지하게 모터의 구동을 제어하고, 조향 토오크가 미리 설정된 값 이상일 경우에는 차량의 속도에 따라 모터의 구동을 제어하여 유체의 공급 유량을 조절하는 것으로 차량의 주행속도가 빠를수록 유체의 공급 유량이 적게 되도록 조절하여 차량의 주행속도에 따른 조향감을 느낄 수 있도록 한다.The present invention controls the driving of the motor so that the pressure of the fluid is maintained between the preset pressure upper limit value and the pressure lower limit value when the steering torque is equal to or less than the preset value, and the motor according to the speed of the vehicle when the steering torque is equal to or greater than the preset value. By controlling the driving flow of the fluid to adjust the supply flow rate of the vehicle as the running speed of the fluid is adjusted so that the supply flow rate of the fluid is reduced to feel the steering feeling according to the running speed of the vehicle.
