도3은 도2의 슬릿 홀의 위치에 따른 차고의 높고 낮은 상태를 나타낸 도면이다.3 is a view showing a high and low state of the garage according to the position of the slit hole of FIG.
이와 같이 구성된 본 발명에 따른 차량의 전자현가장치의 동작을 첨부한 도면 도2 및 도3을 참조하여 상세히 설명하면 다음과 같다.The operation of the electronic suspension device for a vehicle according to the present invention configured as described above will be described in detail with reference to FIGS. 2 and 3.
먼저, 차량의 정지 또는 진행중 바퀴가 노면의 굴곡에 따라 상하로 움직이게 되면 바퀴의 일정 위치에 연결된 리지드 액슬(rigid axle) 및 차체가 연동하게 된다.First, when the wheel is moved up and down according to the curvature of the road while the vehicle is stopped or in progress, the rigid axle and the body connected to the predetermined position of the wheel are interlocked.
이때, 와트링크(12)의 일정 위치에 설치된 링크(11a, 11b)가 연동하게 되는데, 이 연동에 따라 도2에 도시된 바와 같은, 상기 와트링크(12)에 설치된 다수의 슬릿 홀(14a~14n)이 형성된 원판(13)이 연동하게 되며, 아울러 포토커풀러(15)는 상기 다수의 슬릿 홀(14a~14n)이 형성된 원판(13)으로 신호를 출력한 후 반사되는 신호를 감지하여 그 결과신호를 출력하게 된다.At this time, the links 11a and 11b installed at a predetermined position of the watt link 12 are interlocked, and as shown in FIG. 2, the plurality of slit holes 14a to the watt link 12 are interlocked. The original plate 13 on which the 14n is formed is interlocked, and the photocoupler 15 detects the reflected signal after outputting the signal to the original plate 13 on which the plurality of slit holes 14a to 14n are formed. The result signal is output.
그러면 전자제어부(16)는 상기 포토커풀러(15)로부터 출력된 신호로부터 원판(13)의 회전에 따른 회전 슬릿수를 감지하여 도3에 도시된 바와 같은 차고의 높고 낮음에 따른 회전각을 판단한 후 그에 따라 차고의 높이를 조절하기 위한 제어신호를 출력하게 된다. 즉, 전자제어부(16)는 상기 포토커풀러(15)로부터 출력된 신호로부터 상기 다수의 슬릿 홀(14a~14b)이 형성된 부분과 상기 다수의 슬릿 홀(14a~14n)이 형성되지 않는 부분을 갖는 원판(13)으로부터 반사되는 신호의 시간 또는 거리로 슬릿 홀의 수를 감지하여 회전각을 판단한 후 판단된 회전각에 따른 차고의 높이를 조절하기 위한 제어신호를 출력하게 된다.Then, the electronic controller 16 detects the number of rotation slits in accordance with the rotation of the disc 13 from the signal output from the photocoupler 15 to determine the rotation angle according to the high and low of the garage as shown in FIG. After that, the control signal for adjusting the height of the garage is output accordingly. That is, the electronic controller 16 may determine a portion where the plurality of slit holes 14a to 14b are formed and a portion where the plurality of slit holes 14a to 14n are not formed from the signal output from the photocoupler 15. After detecting the number of slit holes by the time or distance of the signal reflected from the original plate 13 to determine the rotation angle and outputs a control signal for adjusting the height of the garage according to the determined rotation angle.
이에 따라 현가특성조절부(17)는 상기 전자제어부(16)에서 출력된 제어신호에 따라 스프링의 공기압 조절 등의 현가특성을 조절하여 차고의 높이를 조절하게 된다.Accordingly, the suspension characteristic adjusting unit 17 adjusts the height of the garage by adjusting the suspension characteristics such as the air pressure of the spring according to the control signal output from the electronic controller 16.
