도 2에 도시된 바와 같이, 본 발명에 따른 전조등 점멸방지 방법은 전조등 작동시 조도센서(도시하지 않음)로 센싱(sensing)하기 위한 신호에 의해 조도센서의 과거 고장 유무를 판단하는 제 1단계(S110)와, 조도센서가 과거에 고장이 발생되지 않았을 시 현재의 고장 유무를 판단하는 제 2단계(S120)와, 조도센서가 과거에 고장 시 현재의 고장유무를 판단하는 제 3단계(S130)와, 제 2단계(S120)와 제 3단계(S130)에서 조도센서가 현재 고장 시 전조등을 전기적으로 즉시 점등하는 제 4단계(S140)와, 제 2단계(S120)와 제 3단계(S130)에서 조도센서가 현재 작동 시 전조등을 전기적으로 점등 유지하도록 하는 제 5단계(S150)와, 조도센서를 통해 외부 조도에 따른 센서 값을 측정하는 제 6단계(S160)와, 조도센서에 의해 센싱된 조도를 기준조도와 비교 판단하는 제 7단계(S170)와, 조도센서의 센서 값이 기준조도를 초과시 2초 후 전조등을 전기적으로 소등하는 제 8단계(S180)와, 조도센서의 센서 값이 기준조도 이하일 경우 1초 후 전조등을 전기적으로 점등하는 제 9단계(S190)를 포함하여 이루어진다.As shown in Figure 2, the headlight blinking prevention method according to the present invention is a first step of determining the past failure of the illumination sensor by a signal for sensing (sensing) to the illumination sensor (not shown) during the operation of the headlight ( S110), the second step (S120) of determining whether there is a current failure when the illuminance sensor has not occurred in the past, and the third step (S130) of determining whether there is a current failure when the illuminance sensor has failed in the past And, in the second step (S120) and the third step (S130), the fourth step (S140) and the second step (S120) and the third step (S130) to electrically turn on the headlight immediately when the illuminance sensor is currently broken In the fifth step (S150) to keep the headlights electrically turned on when the light sensor is currently operating in operation, and the sixth step (S160) of measuring the sensor value according to the external light through the light sensor, and sensed by the light sensor The seventh step (S170) of comparing the illuminance with the reference illuminance; Eighth step (S180) to turn off the headlights after 2 seconds if the sensor value of the degree sensor exceeds the standard illuminance (S180), and if the sensor value of the illuminance sensor is less than the standard illuminance (S180), the ninth step of electrically turning on the headlight after 1 second S190) is made.

먼저, 운전자가 전조등을 작동하게 한 이후 상술한 단계들이 행해진다.First, the above-described steps are performed after the driver has operated the headlamp.

상기 제 1단계(S110)는 전조등이 온(ON) 되었을 때 조도센서의 과거 고장 여부를 판단하는 단계이다.The first step (S110) is a step of determining whether the illuminance sensor is in the past when the headlamp is turned on.

그리고, 상기 제 2단계(S120)는 제 1단계(S110)의 비교 판단 결과, 과거에 조도센서가 정상적이었다면 현재의 고장 여부를 판단하는 단계이다.Then, the second step (S120) is a step of determining whether the current failure if the illumination sensor in the past was normal as a result of the comparison determination of the first step (S110).

또한, 상기 제 3단계(S130)는 제 1단계(S110)의 비교 판단 결과 과거에 조도센서가 고장이었을 경우 현재도 고장인지를 비교 판단 하는 단계이다.In addition, the third step (S130) is a step of comparing whether or not the failure even if the illumination sensor in the past as a result of the comparison determination of the first step (S110) in the past.

한편, 상기 제 4단계(S140)는 제 2단계(S120)와 제 3단계(S130)에서 현재 조 도센서가 고장이라면 전조등(도시하지 않음)을 자동적으로 즉시 점등(ON)시키는 단계이다.On the other hand, the fourth step (S140) is a step of automatically turning on the headlight (not shown) automatically if the current light sensor in the second step (S120) and the third step (S130) is broken.

이때, 상기 제 1단계(S110)에서 제 4단계(S140)는 페일 세이프(fail safe)라 한다.In this case, the fourth step S140 in the first step S110 is called fail safe.

상기 페일 세이프라 함은 시스템이 고장이나 실패하여 이상이 생겼을 때 출력이 잘못되었어도 안전하게 출력이 되도록 하는 것을 말한다. The fail safe means to output safely even if the output is wrong when the system malfunctions or fails.

그리고, 기계설비나 장치 등의 조작을 잘못해도 재해나 사고가 일어나지 않도록 하는 구조로써 다중안전이라고 한다.In addition, multi-safety is referred to as a structure that prevents a disaster or an accident even if an operation of a mechanical facility or a device is incorrectly performed.

그리고, 상기 제 5단계(S150)는 제 2단계(S120)와 제 3단계(S130)에서 현재 조도센서가 고장이라도 전조등을 자동적으로 오프(OFF)시키지 않고 전조등을 전기적으로 점등(ON) 유지시키는 단계이다.The fifth step (S150) is to maintain the headlights electrically turned on (ON) without automatically turning off the headlights even if the current illuminance sensor fails in the second step (S120) and the third step (S130). Step.

즉, 상기 조도센서가 고장여부에 상관없이 제 4단계(S140)와 제 5단계(S150)를 수행하면서 전조등은 점등되거나 점등을 유지하게 된다.That is, the headlight is turned on or maintained while performing the fourth step (S140) and the fifth step (S150) regardless of whether the illuminance sensor is broken.

또한, 제 6단계(S160)는 전조등이 점등되어 있는 상태에서 조도센서의 센서 값을 측정하는 단계이다.In addition, the sixth step (S160) is a step of measuring the sensor value of the illuminance sensor in the state that the headlight is turned on.

그리고, 상기 제 7단계(S170)는 외부조도 값을 기준조도값과 비교 판단하는 단계이다.The seventh step S170 is a step of comparing the external illuminance value with the reference illuminance value.

이때, 상기 제 8단계(S180)는 제 7단계(S170)에서 외부의 조도값이 기준조도를 초과할 경우 2초 후에 자동으로 전조등이 소등되도록 하는 단계이다.In this case, the eighth step S180 is a step in which the headlight is automatically turned off after two seconds when the external illuminance value exceeds the reference illuminance in the seventh step S170.

그리고, 상기 제 9단계(S190)는 제 7단계(S170)에서 외부의 조도값이 기준조 도 이하일 경우 1초 후에 자동으로 전조등이 점등되도록 하는 단계이다.In the ninth step S190, when the external illuminance value is less than or equal to the reference illuminance, the headlamp is automatically turned on after 1 second.

한편, 상술한 제 1단계(S110)에서 제 9단계(S190)는 연속되게 계속 행해지도록 알고리즘을 형성한다.
Meanwhile, in the above-described first step S110, the ninth step S190 forms an algorithm to be continuously performed.

상기한 바와 같이 본 발명에 따른 전조등 점멸방지 방법에 의하면, 자동차의 전조등을 작동한 후 페일 세이프로써 전조등을 소등시키지 않고 점등된 상태를 유지하며 외부조도와 비교하여 점멸시킴으로써 전조등의 깜빡거림을 방지하여 운전자의 시야를 충분히 확보하고, 전방 운전자에 불쾌감을 주지 않는 효과가 있다.  As described above, according to the method of preventing the headlight flickering according to the present invention, after operating the headlight of the vehicle, the headlight is turned on without failing to turn off the headlight, and the lamp is flickered by comparing with external lighting to prevent flicker of the headlight. There is an effect that ensures sufficient visibility of the driver, and does not give a discomfort to the driver ahead.
