Abstract

본 발명은 차량의 주행 상황에 따라 항상적절한 조타력을 유지할 수 있도록 하고, 조향감의 유지 성능이 주로 소프트웨어적으로 결정되게 하여 하드웨어의 설계를 간단히 할 수 있도록 하는 것이다.According to the present invention, it is possible to maintain the proper steering power at all times according to the driving situation of the vehicle, and to simplify the design of the hardware by mainly determining the maintenance performance of the steering feeling in software.

본 발명은 차량의 주행 속도와 핸들의 토크를 이용하는 것으로서, 차량의 주행속도를 차속 센서(11)로 검출함과 아울러 핸들의 토크를 토크 센서(12)로 검출하고 검출한 차량의 주행 속도 및 핸들의 토크롤 ECU(13)가 연산하여 구동 제어신호를 발생하며, 발생한 구동 제어신호에 따라 액츄에이터(14)를 작동시켜 보타력의 크기를 조절하며, 파워실린더(15)에서 보타력이 발생되게 하는 것으로서 제어 오차를 제거하여 차량의 가변되는 주행 상태에 적절한 조향감을 제공할 수 있고 적절한 조향감 유지 성능이 소프트웨어적으로 결정되어 피니언 밸브를 비롯한 액츄에이터 어셈블리의 설계를 간단하게 할 수 있다.The present invention utilizes the traveling speed of the vehicle and the torque of the steering wheel. The driving speed of the vehicle is detected by the vehicle speed sensor 11 and the torque of the steering wheel is detected by the torque sensor 12. The torque roll ECU 13 calculates a driving control signal, operates the actuator 14 according to the generated driving control signal, adjusts the magnitude of the holding force, and causes the holding force to be generated in the power cylinder 15. As a result, control errors can be eliminated to provide a proper steering feeling for the vehicle's varying driving conditions, and an appropriate steering maintaining performance can be determined by software to simplify the design of the actuator assembly including the pinion valve.
