Current sensors(S1,S2) are each connected to the common touching line of the first lamp array and the second lamp array and a signal line from the current sensors is fed back to the ECU and output of the ECU is transmitted to the diagnosing switch again. The diagnosing switch is a push-button switch and the push button unit(11-1) has LED(Light Emitting Diode)(13). After pushing the diagnosing switch if checking luminescence from the LED, malfunction of each lamp is checked.

Description

자동차 램프류 자가진단장치Automobile Lamps Self Diagnosis Device

본 발명은 자동차 램프류 자가진단장치에 관한 것으로서, 더욱 상세히는 자동차에 설치된 제동등, 방향지시등 등의 각종의 램프류의 단선 등의 고장을 검출하는 자가진단장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-diagnosis apparatus for automobile lamps, and more particularly, to a self-diagnosis apparatus for detecting a failure of various lamps such as a braking lamp and a direction indicator lamp installed in a motor vehicle.

자동차에는 전,후방차량으로 운전자의 의사를 전달하기 위한 신호체계로서 제동등, 방향지시등, 미등 등의 각종의 램프류를 차량 전후방에 장착하고 있다.Automobiles are equipped with various lamps such as brake lights, turn signals, tail lights, etc. in front and rear of the vehicle as a signal system for communicating the driver's intention to the front and rear vehicles.

따라서 다수개의 램프류가 사용되므로 각각의 램프류의 수명이 각각 다른 표준편차를 가지면서 종료됨으로서 해당 램프가 단선 등의 고장이 있는지 모르고 주행하게 되어 교통사고를 유발하게 되는 문제점을 가진다.Therefore, since a plurality of lamps are used, the lifespan of each lamp is terminated with a different standard deviation, so that the corresponding lamp may be driven without knowing that there is a breakdown, etc., causing traffic accidents.

더욱이 운전자는 이러한 자신의 차량의 램프류의 고장상태를 제3자가 알려주지 않으면 알기 어렵고 각각의 조작스위치를 조작하면서 각각의 램프의 고장상태를 검사하여야 하는 불편함을 가지고 있다.Moreover, it is difficult for the driver to know the third party's failure state of the lamps of his vehicle, and it is inconvenient to check the failure state of each lamp while operating each operation switch.

본 발명에서는 상기한 종래 기술의 문제점을 감안하여, 별도로 운전자의 개별 스위치류의 조작업이 단일의 램프자가진단스위치를 조작하여 봄으로서 각각의 램프의 고장상태를 용이하게 판별하게 함으로서 자가진단을 가능하게하여 교통사고를 미연에 방지하는 것을 목적으로 한다.In the present invention, in view of the above-mentioned problems of the prior art, the self-diagnosis is possible by allowing the operation of the individual switches of the driver to separately determine the failure state of each lamp by operating a single lamp self-diagnosis switch. It aims to prevent traffic accidents in advance.

Fig. 4 is a block diagram for explaining the operation logic of the self-diagnosis apparatus for automobile lamps of the present invention.

제1도와 같이 구성되는 본 발명의 자동차 램프류 자가진단장치를 설명한다.The motor vehicle lamp self-diagnostic apparatus of this invention comprised as FIG. 1 is demonstrated.

통상적으로 내방에 작동프로그램을 내장함으로서 다양한 자동차 전장품을 제어하는 E.C.U.(10) 및 구동용의 밧데리(B)를 구비하고 본 발명의 목적을 달성하기 위하여, 상기의 E.C.U.(10)로 입력트리거하는 진단스위치(11) 및 상기 E.C.U.(10)의 출력이 입력되는 디코더(12)는 각각의 제1램프어레이(L1,L2,L3) 및 제2램프어레이(,L4,‥‥)의 각각의 램프(L1,L2,L3,L4,‥‥)에 접선하고, 상기의 제1램프어레이(L1,L2,L3) 및 제2램프어레이(,L4,‥‥)의 공통 접지선에는 전류센서(S1,S2)가 각각 접속되고 전류센서(S1,S2)로부터의 신호선은 다시 E.C.U.(10)로 피드백하고 E.C.U.(10)의 출력은 다시 자가진단스위치(11)로 보내어 진다.In general, a built-in operation program includes an ECU 10 for controlling a variety of automotive electronics and a battery B for driving, and in order to achieve the object of the present invention, the diagnosis is triggered by the ECU 10. The decoder 11 into which the switch 11 and the output of the ECU 10 are input includes the respective lamps of the first lamp arrays L1, L2, L3 and the second lamp arrays L4,. It is connected to L1, L2, L3, L4, ..., and the common ground line of the first lamp array L1, L2, L3 and the second lamp array (L4, ...) is connected to the current sensors S1, S2. Are connected to each other, the signal lines from the current sensors S1 and S2 are fed back to the ECU 10, and the output of the ECU 10 is sent to the self-diagnosis switch 11 again.

상기에서 제1램프어레이(L1,L2,L3) 및 제2램프어레이(,L4,‥‥)라 함은 각각의 기능을 수행하는 램프 등의 배열, 예를들면 제1램프어레이(L1,L2,L3)는 제동등어레이, 제2램프어레이(,L4,‥‥)는 방향지시등어레이 등으로 전장배선의 단위인 것이다.In the above description, the first lamp arrays L1, L2, L3 and the second lamp arrays (L4, ...) are arrays of lamps for performing respective functions, for example, the first lamp arrays L1, L2. L3 is a braking lamp array and a second lamp array (L4, ...) is a direction indicating lamp array, which is a unit of electric wiring.

진단스위치(11)는 통상적인 푸쉬버턴스위치로서 구성하여 운전석의 패널 또는 측방에 배치할 수 있으나, 바람직하게는 자주 사용되는 기능은 아니므로 운전석의 패널측방 등에 별도의 도식적인 지시수단을 가지면서 배설하여 두는 것이 좋다.The diagnostic switch 11 may be arranged as a general push button switch and disposed on the panel or side of the driver's seat. However, since the diagnostic switch 11 is not a frequently used function, the diagnostic switch 11 is provided with a separate schematic indicating means such as a panel side of the driver's seat. It is good to leave.

또한 진단스위치(11)는 제1도에 도시하는 바와 같이, 푸쉬버턴부(11-1)가 ON 시에는 점등하도록 내장된 LED 발광체(13)를 가지게 하는 것이 좋고 별도의 무이상표시램프를 장착하여도 무방하다.In addition, the diagnostic switch 11, as shown in Figure 1, it is preferable to have a built-in LED light emitting element 13 so that the push button (11-1) is turned on when the ON button 11-1 is ON, it is equipped with a separate no-error display lamp You may.

상기하는 기본적인 구성에서 E.C.U.(10)에 내장되는 진단 프로그램은 제3도와 관련하여 하기와 같은 작동을 수행한다.In the basic configuration described above, the diagnostic program embedded in the E.C.U. 10 performs the following operations with respect to FIG.

진단스위치(11)로부터의 입력트리거신호에 기하여 E.C.U.(10)는 디코더(12)로 소정회수(예를들면 3회)와 시간간극(T)으로서 검출펄스를 각 램프별로 순차적으로 발생시키고, 디코더(12)는 이 신호를 각 램프로 순차공급하여 제1램프어레이(L1,L2,L3) 및 제2램프어레이(,L4,‥‥) 등에 접속된 공통 접지선에서의 전류센서(S1,S2)는 전류검출결과신호를 E.C.U.(10)로 피드백하여 모든 램프가 정상이라면 진단스위치(11) 자체의 LED 발광체(13)를 구동하여 푸쉬버턴부(11-1), 또는 별도의 램프를 구동하여 수초간 점멸하게 함으로서 램프의 무이상을 알려주게 된다.Based on the input trigger signal from the diagnostic switch 11, the ECU 10 sequentially generates a detection pulse for each lamp as a predetermined number of times (for example, three times) and a time interval T to the decoder 12. (12) sequentially supplies this signal to each lamp, and the current sensors (S1, S2) on a common ground line connected to the first lamp array (L1, L2, L3), the second lamp array (, L4, ..., etc.) If the current detection result signal is fed back to the ECU 10, and all the lamps are normal, the LED light emitting element 13 of the diagnostic switch 11 itself can be driven to drive the push button unit 11-1 or a separate lamp. By blinking for a second, the lamp will indicate that nothing is wrong.

더욱 상세히는 제4도의 블록다이아그램에서와 같이, 진단스위치(11)를 ON하여 진단을 시작(100)하면, 램프의 진단수를 카운트하여(101)가면서 램프의 현재 진단순번이 총램프의 개수(N)보다 작으면(No), 램프진단 펄스를 발하여(102), 접지선의 전류를 센싱(103)하여 해당 램프의 이상(HIGH)이 없으면, 순환루프로서 반복(104)하고, 모든 램프가 정상이면 진단스위치(11) 자체의 LED발광체(13)를 구동하여 푸쉬버턴부(11-1)를 수초간 점멸하게 하여(201) 종료한다.More specifically, as shown in the block diagram of FIG. 4, when the diagnosis switch 11 is turned on to start diagnosis 100, the number of diagnosis of the lamp is counted (101) while the current diagnosis sequence of the lamp is the total number of lamps. If less than (N) (No), the lamp diagnosis pulse is issued (102), the current of the ground line is sensed (103), if there is no abnormality (HIGH) of the corresponding lamp, it is repeated 104 as a circulating loop, and all lamps If normal, the LED light emitting body 13 of the diagnostic switch 11 itself is driven to cause the push button part 11-1 to blink for a few seconds (201).

진단순번이 총램프의 개수보다 작거나 같고(Yes) 각 램프의 이상이 있으면(LOW), 진단스위치(11) 자체의 LED 발광체(13)를 구동하여 푸쉬버턴부(11-1)를 수초간 지속발광하게(202)하여 종료한다.(300)If the diagnosis sequence is less than or equal to the total number of lamps (Yes) and there is an abnormality of each lamp (LOW), the LED button 13 of the diagnosis switch 11 itself is driven to drive the pushbutton 11-1 for several seconds. Continue to emit light (202) and terminate. (300)

따라서, 운전자는 진단스위치(11)를 누른 후에 수초후의 발광수단에서의 발광을 확인하면 각 램프의 이상이 없음을 용이하게 알게 되는 것이다.Therefore, when the driver confirms the light emission from the light emitting means a few seconds after pressing the diagnostic switch 11, the driver can easily know that there is no abnormality of each lamp.

이상과 같은 본 발명의 자동차 램프류 자가진단장치는 종래의 개별적인 스위치류의 조작에 의한 램프의 진단없이 진단스위치의 조작만으로도 모든 램프류의 이상을 감지하게하여 램프류의 이상에 의한 교통사고를 미연에 방지하는 유용성을 가지는 것이다.Automotive lamps self-diagnosis apparatus of the present invention as described above to detect the abnormality of all lamps only by operating the diagnostic switch without the diagnosis of the lamps by the operation of the conventional individual switches to prevent traffic accidents due to the lamps in advance. It is useful.
