Zusammenfassung: | The present invention relates to a vehicle behavior estimation system for estimating a vehicle behavior in order to control a damping force of a variable damper installed between an axle and a vehicle body. According to the present invention, the vehicle behavior estimation system comprises: four dampers installed on each wheel; two or more wheel sensors to detect wheel vertical speed; one integrated sensor installed on one side of a vehicle body; and an electronic control unit (ECU) controlling a damping force of the damper by calculating a roll value, a pitch value, and a bounce value of the vehicle body estimated through the integrated sensor, and the vertical speed of the wheel, respectively. According to the configuration of the present invention, installation of a sensor is free and management is easy.
본 발명의 차량 거동 추정 시스템은, 차축과 차체 사이에 설치되는 가변 댐퍼의 감쇠력을 제어하기 위하여, 차량의 거동을 추정하는 차량 거동 추정 시스템에 있어서, 각 휠에 설치되는 4개의 상기 댐퍼, 휠 수직 속도를 검출하는 2개 이상의 휠 센서, 상기 차체 일측에 설치되는 1개의 통합 센서, 및 상기 통합 센서를 통해서 추정되는 차체의 롤 값, 피치 값, 및 바운스 값과 상기 휠 수직 속도를 각각 계산함으로써 상기 댐퍼의 감쇠력을 제어하는 ECU를 포함한다. 이와 같은 본 발명의 구성에 의하면, 센서의 설치가 자유롭고 관리가 용이하다. |
