차량의 감광식 룸램프 제어방법{Control method of sensitive room lamp for automobile}Control method of sensitive room lamp for automobile

본 발명은 차량의 감광식 룸램프 제어방법에 관한 것으로서, 더욱 상세하게는 조도센서, 핸들록 스위치 등의 신호를 이용하여 룸램프의 ON/OFF 동작을 제어할 수 있는 방법을 제공함으로써, 주위 환경에 따라 룸램프가 점등되도록 할 수 있어 배터리 전원의 효율적인 사용이 가능하고, 특히 어두운 곳에 주차 후 시동을 OFF 할 경우에도 운전자가 도어 핸들을 찾는데 어려움이 없도록 한 차량의 감광식 룸램프 제어방법에 관한 것이다.The present invention relates to a method of controlling a photosensitive room lamp of a vehicle, and more particularly, by providing a method of controlling an ON / OFF operation of a room lamp by using signals such as an illuminance sensor and a steering lock switch. The room lamp can be turned on according to the present invention, so that the efficient use of battery power is possible. In particular, a method for controlling a photosensitive room lamp of a vehicle in which the driver has no difficulty in finding the door handle even when the vehicle is turned off after parking in a dark place will be.

일반적으로 차량의 감광식 룸램프는 별도의 수조작에 의한 ON/OFF 작동 이외에 도어의 개폐상태에 따라 자동으로 ON/OFF 되면서 어두운 실내를 밝혀주는 편의수단 중의 하나이다.In general, the photosensitive room lamp of the vehicle is one of the convenience means that illuminates the dark room while being automatically turned ON / OFF according to the opening / closing state of the door in addition to the ON / OFF operation by a separate manual operation.

종래의 감광식 룸램프는, 도 1에 도시한 바와 같이, 이그니션 스위치의 OFF 상태에서 전체 도어 중 어느 1개라도 열리면 도어 스위치의 ON 동작에 의해 점등되고, 다시 도어 닫힘이 발생하면 약 2초 동안 점등상태를 유지한 후 서서히 감광하여 약 4초 후 소등되는 동작 알고리즘으로 되어 있다.As shown in FIG. 1, the conventional photosensitive room lamp is turned on by turning on the door switch when any one of all doors is opened in the OFF state of the ignition switch, and is turned on for about 2 seconds when the door is closed again. It is an operating algorithm that gradually diminishes after maintaining the lighting state and turns off after about 4 seconds.

여기서, 도어 스위치의 ON 시간이 0.1초 이하의 경우에는 감광동작을 하지 않으며, 감광동작 중 이그니션 스위치가 ON 되면 즉시 출력이 OFF 된다.Here, if the ON time of the door switch is less than 0.1 second, the photosensitive operation is not performed. If the ignition switch is turned on during the photosensitive operation, the output is immediately turned off.

그러나, 종래의 감광식 룸램프는 아래와 같은 여러 문제점을 갖고 있다.However, conventional photosensitive room lamps have various problems as follows.

1) 주위 환경에 따른 사용시의 불편현상이 발생한다.1) Uncomfortable use occurs depending on the surrounding environment.

이그니션 스위치의 OFF 상태에서 도어를 열기 전에는 룸램프가 ON 되지 않기 때문에 만약에 주위 환경이 어두운 곳에 차량을 주차한 후 이그니션 스위치를 OFF 할 경우 차량 내부에는 조명이 없으므로, 운전자가 도어를 열려고 할 때 도어 핸들을 찾는데 어려움이 발생한다.Since the room lamp does not turn on before the door is opened while the ignition switch is in the OFF state, if the ignition switch is turned off after parking the vehicle in a dark environment, there is no lighting inside the vehicle. Difficulty finding a handle

2) 배터리 전원의 사용이 비효율적이다.2) The use of battery power is inefficient.

주위 환경의 밝기(예를 들면, 낮과 밤)에 관계없이 감광식 룸램프가 점등되므로, 배터리 전원이 비효율적으로 사용된다.Since photosensitive room lamps light regardless of the brightness of the environment (for example, day and night), battery power is inefficiently used.

따라서, 본 발명은 이와 같은 점을 감안하여 안출한 것으로서, 감광식 룸램프의 제어조건으로 조도센서의 신호와 핸들록 스위치의 신호를 추가하여 주위 환경의 밝기를 고려할 수 있고 도어의 개폐조작 전에라도 룸램프를 점등시킬 수 있도록 함으로써, 주위 환경에 따라 룸램프가 점등되도록 할 수 있어 배터리 전원의 효율적인 사용이 가능하고, 특히 어두운 곳에 주차 후 시동을 OFF 할 경우에도 운전자가 도어 핸들을 찾는데 어려움이 없도록 한 차량의 감광식 룸램프 제어방법을 제공하는데 그 목적이 있다.Therefore, the present invention has been devised in view of the above, and it is possible to consider the brightness of the surrounding environment by adding the signal of the illumination sensor and the signal of the handlelock switch as a control condition of the photosensitive room lamp, and even before opening and closing the door. By enabling the room lamp to be turned on, the room lamp can be turned on according to the surrounding environment, enabling efficient use of battery power, and it is not difficult for the driver to find the door handle even when the vehicle is turned off after parking in a dark place. It is an object of the present invention to provide a method for controlling a photosensitive room lamp of a vehicle.

상기 목적을 달성하기 위한 본 발명은 조도센서에 의한 주위 환경의 밝기를 판단하는 단계와, 주위 환경이 어두운 경우 이그니션 스위치의 ON/OFF 여부를 판단하는 단계와, 이그니션 스위치의 ON 상태에서 적어도 1개의 도어 스위치에 대한 ON/OFF 여부를 판단하는 단계와, 도어 스위치가 ON 상태이면 룸램프를 점등시키는 단계와, 룸램프 ON 동작상태에서 적어도 1개의 도어 스위치에 대한 ON/OFF 여부를 판단하는 단계와, 도어 스위치가 OFF 상태이면 룸램프를 2초 동안 점등시킨 후 감광하여 4초 후 소등시키는 단계를 포함하는 것을 특징으로 한다.The present invention for achieving the above object is a step of determining the brightness of the ambient environment by the illumination sensor, determining whether the ignition switch ON / OFF when the ambient environment is dark, and at least one in the ON state of the ignition switch Determining whether the door switch is ON / OFF, turning on the room lamp when the door switch is ON, and determining whether the door switch is ON / OFF in the room lamp ON operation state; If the door switch is in the OFF state, the room lamp is turned on for 2 seconds, and then dimmed after 4 seconds.

도 2는 본 발명의 감광식 룸램프 제어방법을 보여주는 동작 알고리즘2 is an operation algorithm showing a photosensitive room lamp control method of the present invention

이하, 첨부한 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명에서는 감광식 룸램프의 제어조건으로 주위 환경의 밝기를 판단하는조도센서의 신호 또는 핸들록 스위치의 신호, 예를 들면 시동키를 삽입하거나 인출하는 신호를 추가로 포함하는 제어방법을 제공한다.The present invention provides a control method further comprising a signal of an illuminance sensor or a signal of a handlelock switch, for example, a signal of inserting or drawing a start key, as a control condition of a photosensitive room lamp. .

이를 위하여, 도 2에 도시한 바와 같이, 차량의 실내에 설치되어 있는 조도센서를 이용하여 실내를 포함하는 그 주위 환경의 밝기를 판단하는 단계를 수행한다.To this end, as shown in FIG. 2, the brightness of the surrounding environment including the interior is determined by using an illumination sensor installed in the interior of the vehicle.

예를 들면, 주위 환경의 밝기가 6.0∼6.4㏓ 범위 이하, 바람직하게는 6.2㏓이하 이면 룸램프의 점등을 위한 조건으로 판정하고, 위의 범위를 넘어서면 룸램프의 소등을 위한 조건으로 판정한다.For example, if the brightness of the surrounding environment is within the range of 6.0 to 6.4 이하 or less, preferably 6.2 ㏓ or less, it is determined as a condition for turning on the room lamp, and when it exceeds the above range, it is determined as a condition for turning off the room lamp. .

위의 단계에서 룸램프의 점등을 위한 조건으로 판정되면 이그니션 스위치의 ON/OFF 여부를 판단하는 단계를 수행한다.If it is determined in the above step that the room lamp is turned on, it is determined whether the ignition switch is turned on or off.

이그니션 스위치의 ON 상태에서는 차량의 운행이나 실내에서 기타 조작이 이루어지고 있는 상황으로 간주할 수 있기 때문에 룸램프의 자동적인 점등을 필요로 하지 않고, 이에 따라 전 단계로 진행한다.When the ignition switch is in the ON state, it can be regarded as a situation in which the vehicle is being operated or other operations are performed indoors, so that the room lamp does not need to be automatically turned on, and thus proceeds to the previous stage.

이그니션 스위치의 OFF 상태로 판단되면 다음 단계로 진행한다.If it is determined that the ignition switch is OFF, proceed to the next step.

위의 단계에서 이그니션 스위치의 OFF 상태로 판정되면 도어 스위치의 ON/OFF 여부를 판단하는 단계를 수행한다.If it is determined that the ignition switch is OFF in the above step, it is determined whether the door switch is ON / OFF.

전체 도어 중에서 어느 1개의 도어가 열리면서 해당 도어 스위치가 ON 되면 다음 단계로 진행한다.If any door is opened and the door switch is turned on, proceed to the next step.

위의 단계에서 도어 스위치의 ON 상태로 판정되면 룸램프의 점등을 위한 단계를 수행한다.If it is determined that the door switch is in the ON state in the above step, the step for turning on the room lamp is performed.

계속해서, 룸램프의 점등시 전체 도어 중 어느 1개의 도어가 재차 닫혔는지의 여부, 즉 도어 스위치의 ON/OFF 여부를 판단하는 단계를 수행한다.Subsequently, when the room lamp is turned on, it is determined whether one of the doors is closed again, that is, whether the door switch is turned on or off.

위의 단계에서 도어 스위치의 OFF 상태로 판정되면 룸램프를 약 2초 동안 점등시킨 후 감광하여 약 4초 후 소등하는 단계를 수행한다.If it is determined that the door switch is in the OFF state in the above step, the room lamp is turned on for about 2 seconds and then dimmed to turn off after about 4 seconds.

한편, 본 발명에서는 룸램프의 점등을 위한 조건으로 핸들록 스위치의 ON/OFF 여부를 판단한 후 이때의 값을 그 조건으로 이용하는 단계를 제공한다.On the other hand, the present invention provides a step for determining whether the handle lock switch is ON / OFF as a condition for the lighting of the room lamp and using the value at this time as the condition.

예를 들면, 위의 단계를 이그니션 스위치의 ON/OFF 여부를 판단하는 단계와 룸램프를 점등시키는 단계 사이에서 수행되며, 이그니션 스위치의 ON 상태에서 핸들록 스위치의 ON/OFF 여부를 판단하여 핸들록 스위치의 ON 상태로 판정되면 룸램프의 점등을 위한 단계로 진행한다.For example, the above steps are performed between determining whether the ignition switch is ON / OFF and turning on the room lamp, and determining whether the handlelock switch is ON / OFF in the ON state of the ignition switch to handle the lock. If it is determined that the switch is in the ON state, the flow proceeds to the step for lighting the room lamp.

즉, 시동키를 빼낸 상태에서는 룸램프의 점등조건이 조성되고, 시동키가 그대로 꽂혀있는 상태에서 룸램프는 점등되지 않는다.That is, the lighting condition of the room lamp is established in the state where the ignition key is removed, and the room lamp does not light when the ignition key is inserted.

이상에서와 같이 본 발명은 다음과 같은 효과를 제공한다.As described above, the present invention provides the following effects.

1) 성능 향상의 효과1) Effect of performance improvement

조도센서의 신호로 점등 여부를 판단하여 밤이나 어두운 곳에서만 룸램프가 점등되게 하므로, 배터리 전원의 효율적인 사용이 가능하다.It is possible to use battery power efficiently because the room lamp is turned on only at night or in the dark by judging whether it is lit by the signal of the illumination sensor.

2) 편의성 향상의 효과2) effect of improving convenience

야간에 조명시설이 없거나 또는 조명시설이 멀리 떨어져 있는 곳에 차량을 주차시킨 후 시동키를 빼낼 경우 차량 내의 룸램프가 자동으로 점등되므로, 운전자가 도어 핸들을 쉽게 찾아 도어를 열 수 있는 편의성이 있다.When the vehicle is parked in a place where there is no lighting or a distant lighting at night, and the ignition key is removed, the room lamp inside the vehicle is automatically turned on, so that the driver can easily find the door handle and open the door.
