상기 ECU(63)는 운전자가 가속페달을 밟는 정도를 감지하여 전기자동차에 구비된 모터나, 일반자동차에 구비된 엔진의 작동을 제어하는 것으로, 차량에 일반적으로 사용되는 것임으로, 이에 대한 더 이상 자세한 설명은 생략한다.The ECU 63 controls the operation of a motor provided in an electric vehicle or an engine provided in a general vehicle by sensing the degree to which the driver steps on the accelerator pedal, and is generally used in vehicles. A detailed description will be omitted.

이때, 상기 ECU(63)는 운전자가 차량의 가속패널을 밟는 정도에 따라 상기 회동구동수단(62)의 작동을 제어하도록 구성된다.At this time, the ECU 63 is configured to control the operation of the rotation driving means 62 according to the degree to which the driver steps on the accelerator panel of the vehicle.

이를 자세히 설명하면, 상기 ECU(63)는 평상시에는 도 7에 실선으로 도시한 바와 같이, 상기 개폐덮개(61)가 상하방향으로 회동되어 공기가 상기 공기통로(11)로 유입되어 발전기(40)가 발전을 하도록 한다.In detail, the ECU 63 normally rotates the opening/closing cover 61 in the vertical direction as shown by the solid line in FIG. to make progress

그리고, 상기 ECU(63)는 운전자가 가속페달을 밟는 정도를 측정하여 운전자가 가속페달을 미리 설정된 정도 이상으로 밟을 경우, 도 7에 점선으로 도시한 바와 같이, 상기 개폐덮개(61)를 닫히는 방향으로 회동시켜 공기통로(11)를 막도록 구성된다.In addition, the ECU 63 measures the degree to which the driver steps on the accelerator pedal, and when the driver steps on the accelerator pedal more than a preset level, as shown by a dotted line in FIG. 7 , the opening and closing cover 61 is closed in the direction It is configured to block the air passage 11 by rotating it.

즉, 운전자가 가속페달을 미리 설정된 정도 이상으로 밟는 다는 것은 운전자가 차량을 가속시킨다는 것인데, 이때, 상기 공기통로(11)가 개방되어 공기가 공기통로(11)로 유입될 경우, 공기저항이 증가되어 차량의 가속에 방해가 된다.That is, when the driver depresses the accelerator pedal more than a preset level, the driver accelerates the vehicle. At this time, when the air passage 11 is opened and air flows into the air passage 11, air resistance increases. This will impede the vehicle's acceleration.

이러한 경우, 상기 제어수단은 상기 개폐덮개(61)를 닫히는 방향으로 회동시켜 공기통로(11)를 막음으로써, 차량의 가속에 방해가 발생되는 것을 방지할 수 있다.In this case, the control means blocks the air passage 11 by rotating the opening/closing cover 61 in the closing direction, thereby preventing an obstacle to the acceleration of the vehicle.
