상기와 같이 구성된 실시 예의 작동에 대하여 설명한다.The operation of the embodiment configured as described above will be described.

도로 주행을 위해서, 운전자는 센서 장착봉(1)덮개를 열고 센서가 장착된 장착봉(1)을 외부로 빼내 필요한 길이에서 고정시키고, 센서의 방향을 아래로 고정시킨다.For driving on the road, the driver opens the cover of the sensor mounting rod (1), pulls out the mounting rod (1) equipped with the sensor to the outside to fix it at the required length, and fixes the direction of the sensor downward.

운전자는 주행차선이 페인트칠로서 표시된 도로에서 핸들 조작으로 자동차를 주행시키며, 운전석에 부설된 센서 스위치(S-1)를 넣고, 콘트롤러(6)상에서 작동을 확인 후, 앞바퀴(2-1)를 주행차선 쪽으로 접근시켜 광 센서(5-1 ·5-2)에서 발신되는 광 신호의 반사점(P-1 ·P-2)이 주행차선(3-1)상에 위치한 것을 콘트롤러(6)에서 확인하고, 구동모터(7) 스위치(S-2)를 넣으면 이때부터 앞바퀴는 앞바퀴 방향 제어장치에 의해서 제어되게 되며, 광센서(5-1 ·5-2)는 반사 수신되는 광 신호를 계속 콘트롤러(6)에 발신하게 된다.The driver drives the vehicle by steering wheel operation on the road marked with paint lanes, inserts the sensor switch S-1 attached to the driver's seat, checks the operation on the controller 6, and then moves the front wheel 2-1. The controller 6 confirms that the reflection points P-1 and P-2 of the optical signal transmitted from the optical sensors 5-1 and 5-2 are located on the driving lane 3-1 by approaching the driving lane. Then, when the drive motor (7) switch (S-2) is inserted, the front wheel is controlled by the front wheel direction control device from this time, the optical sensor (5-1 · 5-2) continues to control the light signal received by the controller ( 6).

주행차선에서 좌측 광 신호 반사점(P-1)이 좌측으로 벗어나면, 좌측 광센서(5-1)는 반사점이 좌측으로 벗어난 신호를 발신하고, 콘트롤러(6)는 이 신호를 수신 ·식별 ·처리하여 앞바퀴 우측방향 구동신호를 구동모터(7)에 발신하며, 이 구동신호를 수신한 구동모터(7)가 구동하고, 구동모터에 순차 연결된 구동기어 (8), 구동봉(4)에 의해서 양 앞바퀴(2-1 ·2-2)는 우측으로 구동하여 좌측 광 신호 반사점(P-1)은 주행차선(3-1)상에 복귀하게 되며, 좌측 광 신호 반사점(P-1)이 주행차선(3-1)상에 복귀한 신호가 좌측 광센서(5-1)에 의해서 콘트롤러에 발신되고, 이 신호를 수신한 콘트롤러는 구동모터(7)에 구동정지 신호를 발신하여 구동모터의 구동을 정지시키며, 다시, 우측 광 신호 반사점(P-3)이 우측으로 벗어나면, 콘트롤러(6)는 우측 광센서(5-2)가 발신하는 신호를 수신 ·식별 ·처리하여 앞바퀴 좌측방향 구동신호를 구동모터(7)에 발신하고, 구동모터(7)의 구동에 의해서 양 앞바퀴(2-1 ·2-2)는 좌측 구동을 하게되어 우 광측 신호 반사점(P-2)은 주행차선(3-1)상에 복귀하며, 우측 광센서(5-2)는 반사점(P-2)이 주행차선(3-1)상에 복귀한 신호를 콘트롤러(6)에 발신하고, 이 신호를 수신한 콘트롤러(6)는 구동모터(7) 구동을 정지시킨다.When the left optical signal reflecting point P-1 deviates to the left in the traveling lane, the left optical sensor 5-1 sends a signal whose reflecting point deviates to the left, and the controller 6 receives, identifies and processes this signal. The driving signal to the front wheel right direction to the drive motor (7), the drive motor (7) receiving the drive signal is driven, both by the drive gear (8), drive rod (4) sequentially connected to the drive motor The front wheels 2-1 and 2-2 are driven to the right, so that the left light signal reflection point P-1 returns to the driving lane 3-1, and the left light signal reflection point P-1 is driving lane. The signal returned on (3-1) is sent to the controller by the left optical sensor 5-1, and the controller receiving the signal sends a drive stop signal to the drive motor 7 to drive the drive motor. When the right light signal reflection point P-3 is deviated to the right, the controller 6 stops the signal from the right light sensor 5-2. The front wheel left direction drive signal is sent to the drive motor 7 by new, identification and processing, and both front wheels 2-1 and 2-2 are driven left by the drive motor 7 and the right light signal The reflection point P-2 returns to the traveling lane 3-1, and the right light sensor 5-2 receives a signal from which the reflection point P-2 returns to the traveling lane 3-1. The controller 6 which transmits to 6) and receives this signal stops driving the drive motor 7.

이 작동의 반복으로서, 자동차 앞바퀴는 제어되어 주행차선(3-1)과 앞바퀴(2-1)사이의 기준거리(A)는 유지되면서 자동차는 주행을 계속하게된다.As a repetition of this operation, the front wheel of the vehicle is controlled so that the vehicle continues to travel while the reference distance A between the driving lane 3-1 and the front wheel 2-1 is maintained.

아스팔트 도로 부분과 페인트칠이 된 주행차선에서 수신되는 광 신호는 서로 다르며, 이 다른 점을 콘트롤러는 수신 ·식별 처리하여 구동신호를 발신한다.The light signals received from the asphalt road part and the painted driving lanes are different from each other, and the controller receives and identifies these differences and transmits driving signals.

일시, 주행차선 주행에서 해제되기 위해서는 구동모터(7) 스위치(S-2)를 끄면 된다.The drive motor 7 switch S-2 may be turned off temporarily to release the vehicle from traveling in the traveling lane.

이 고안은 고속도로 등에서 장거리 주행을 행할 시, 장치를 작동시켜 차선주행을 하면, 부주의, 또는 졸음으로 인해 발생하는 사고를 예방할 수 있다.This design prevents accidents caused by carelessness or drowsiness when driving in lanes by operating the device when driving long distances on a highway or the like.
