구동휠의 회전속도(W)를 감지하는 휠회전 속도감지부(1)와, 트로틀 밸브(throttle valve) 개도각()을 감지하는 개도각 감지부(2)와, 상기 휠회전 속도감지부(1) 및 트로틀 밸브 개도각 감지부(2)로 부터 구동 휠의 회전속도(W) 및 트로틀 밸브 개도각()을 인식하여 이들 두 값을 비교하여 구동 휠의 상태를 판단하여 스위치(4)를 제어하는 ECU(3)와, ECU(3)의 제어에 따라 스위칭하여 제어박스(6)의 코일(5)에 전류를 흘려 제어밸브(7)에 의해 가속패달(8)이 더이상의 가속이 이루어지지 않도록 하는 스위치(4)로 구성됨을 특징으로 한다.Wheel rotation speed detection unit (1) for detecting the rotational speed (W) of the drive wheel, and opening angle of the throttle valve ( Opening angle detection unit 2 for sensing the rotational speed (W) and the throttle valve opening angle of the drive wheel from the wheel rotation speed detection unit 1 and the throttle valve opening angle detection unit (2) ), The ECU 3 controls the switch 4 by judging the state of the driving wheel by comparing these two values, and the coil 5 of the control box 6 by switching under the control of the ECU 3. It is characterized in that the acceleration pedal (8) by the control valve (7) to flow a current to the switch 4 to prevent further acceleration.
미 설명부호 9는 트로틀 바디이다.US 9 is a throttle body.
상기와 같이 구성된 본 고안의 일실시예를 설명하면 다음과 같다.Referring to one embodiment of the present invention configured as described above are as follows.
도 3은 구동휠의 회전속도(W)와 트로틀 밸브 개도각()의 관계를 나타낸 것으로서, 본 고안에서는 이의 관계를 이용하여 ECU(3)에서 구동휠의 헛돌고 있음을 감지하여 더 이상의 가속이 이루어지지 않고 감속이 이루어질 수 있도록 한 것이다.3 shows the rotational speed (W) of the drive wheel and the opening angle of the throttle valve ( In the present invention, by using this relationship, the ECU 3 detects that the driving wheel is spinning, so that no further acceleration can be made and the deceleration can be made.
차량의 주행하게되면, ECU(3)에서는 휠 회전 속도감지부(1) 및 개도각 감지부(2)를 통해 휠 회전속도(W) 및 트로틀 밸브 개도각()을 인식하게 되고, 이들 두 값을 일정상수(k)를 이용하여 비교하게 된다.When the vehicle is driven, the ECU 3 transmits the wheel rotation speed W and the throttle valve opening angle through the wheel rotation speed detection unit 1 and the opening angle detection unit 2. ), And these two values are compared using a constant (k).
비교결과 구동휠이 트로틀 밸브의 개도각에 비해 일정이상속도로 회전하고 있을 경우(Wk)에 ECU(3)에서는 구동휠이 헛돌고 있음으로 인식하여 스위치(4)를 온 스위칭시키게 된다.As a result of the comparison, when the driving wheel is rotating at a speed higher than the opening angle of the throttle valve (W k ), The ECU 3 recognizes that the driving wheel is spinning and turns on the switch 4.
상기 스위치(4)가 온 스위칭하게 되면, 제어박스(6)의 코일(5)에 전류가 흐르게 되고, 이에 따라 코일(5)이 전자석으로 작용하여 제어밸브(7)에 의해 가속패달(8)이 당겨지게되므로서, 1차 감속이 이루어지도록 하고, 운전자가 가속패달(8)을 계속 패달을 밟아도 더이상의 가속이 이루어지지 않도록 한다.When the switch 4 is switched on, a current flows in the coil 5 of the control box 6, whereby the coil 5 acts as an electromagnet and the acceleration pedal 8 is driven by the control valve 7. As this is pulled, the primary deceleration is made, and no further acceleration is made even if the driver continues to step on the accelerator pedal 8.
이상에서 설명한 바와 같이, 구동휠이 헛돌게 되면 이를 감지하여 가속패달을 밟아도 구동휠이 헛돌고 있는 동안에는 더이상의 가속이 이루어지지 않도록 하므로서, 사용자를 사고의 위험으로 부터 보호하게 되는 효과가 있는 것이다.As described above, even if the driving wheel is detected by turning the accelerator pedal to detect this, even when the driving wheel is idle, no further acceleration is made, thereby protecting the user from the risk of an accident.
