본 발명은 자동변속기의 고장 표시장치에 관한 것으로, 특히 자동변속기 차량에 있어 변속레버가 주차위치에 놓여 있을때 시스템의 정상여부를 판단하여 주차표시램프의 동작 모우드를 변화시킴에 의해 고장표시가 가능토록 한 자동변속기의 고장 표시장치에 관한 것이다.The present invention relates to a failure display device of an automatic transmission, in particular, in the automatic transmission vehicle when the shift lever is placed in the parking position by determining whether the system is normal by changing the operation mode of the parking indicator lamp so that the failure can be displayed. A fault indication device of an automatic transmission is provided.
근래 승용차로부터 트럭, 버스등 대형차량에 까지 자동차의 운전 편의성을 도모하기 위해 자동변속기를 채용하고 있는 추세에 있으나, 자동변속기 시스템 자체의 복잡성으로 인해 사소한 고장이 발생하더라도 조기에 발견하기가 어려워 지나치기가 쉽고 다만 경험적으로 고장을 판단하여 때늦게 전문가에게 수리를 의뢰하는 등의 문제점이 있다.In recent years, automatic transmissions have been adopted to promote driving convenience from passenger cars to trucks and buses, but due to the complexity of the automatic transmission system itself, it is difficult to detect even a small failure early. There are problems such as easy and empirical determination of failures and requesting repairs later.
따라서, 본 발명은 이와같은 문제점을 해결하기 위해 안출된 것으로, 자동변속기의 전자제어장치에서 시스템 고장을 검출하였을때 이에 반응한 특정신호를 발생시켜 기존에 설치된 운전석 계기판의 주차표시램프 구동회로로 인가하므로써, 운전자에게 자동변속기의 고장발생을 즉각적으로 알려줄 수 있는 자동변속기의 고장 표시장치를 제공하기 위한 것이다.Accordingly, the present invention has been made to solve such a problem, when generating a specific signal in response to the detection of a system failure in the electronic control device of the automatic transmission is applied to the parking display lamp driving circuit of the existing driver's seat instrument panel Thus, it is to provide a failure indicator of the automatic transmission that can immediately inform the driver of the failure of the automatic transmission.
이하 첨부도면을 참고하여 본 발명의 일 실시예에 대해 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 발명에 따른 자동변속기 고장표시장치의 전기적 회로 구성도로서, 통상 자동변속기의 변속레버에 설치된 인히비터 스위치(12)를 통해 그 레버의 변속위치(P,R,N,D,2,L)를 검출하기 위한 신호공급라인이 자동변속기제어장치(TCU; 10)의 입력단에 연결되며, 변속기제어장치(10)는 내부 신호처리에 의해 변속제레버가 주차(P)위치에 있을때 이에 반응한 램프구동신호 SL를 발생하여 그 하나의 출력단으로 출력한다. 출력단에 연결된 주차표시램프 Lp의 구동회로, 즉 스위칭 트랜지스터의 베이스단자로 하이레벨 구동신호가 인가되면 트랜지스터가 턴 온되어 주차표시램프 Lp로 전원 B이 공급되므로써 주차표시램프가 점등하게 된다.1 is an electrical circuit diagram of an automatic transmission failure display device according to the present invention, and the shift positions P, R, N, D, and 2 of the lever are normally provided through an inhibitor switch 12 installed in the shift lever of the automatic transmission. The signal supply line for detecting, L is connected to the input terminal of the automatic transmission control unit (TCU) 10, and the transmission control unit 10 is connected to an internal signal processing when the transmission lever is in the parking (P) position. The ramp driving signal SL reacted is generated and output to one output terminal. When a high level driving signal is applied to the driving circuit of the parking display lamp Lp connected to the output terminal, that is, the base terminal of the switching transistor, the transistor is turned on so that the power supply B is supplied to the parking display lamp Lp, thereby turning on the parking display lamp.
상기 주차표시램프 Lp는 통상 운전석 앞에 계기판에 다른 표시램프들과 함께 조합 설치된다. 또한 상기 변속기제어장치(10)는 램프구동신호 발생동작 이외에도 내부에 기억된 프로그램에 의해 각종센서로부터 입력된 신호의 연산값에 반응한 시스템 동작을 기준치와 비교하여 이상이 있을때 고장진단 데이타를 저장하는 기능이 있다.The parking indicator lamp Lp is usually installed in combination with other indicator lamps on the dashboard in front of the driver's seat. In addition to the ramp drive signal generation operation, the transmission control device 10 stores failure diagnosis data when there is an error by comparing a system operation in response to an operation value of a signal input from various sensors by a program stored therein with a reference value. There is a function.
본 발명은 위와같이 변속기제어장치(10)에 의한 주차표시램프 Lp의 구동을 변속레버가 주차위치(P)에 있음을 나타내는 것 뿐만아니라 자동변속기 시스템의 이상유무를 나타내는 고장표시장치로서 이용하고자 하는 것이다.The present invention intends to use the driving of the parking indication lamp Lp by the transmission control device 10 as above as a failure display device not only indicating that the shift lever is in the parking position P but also indicating the abnormality of the automatic transmission system. will be.
이를 위해 상기 변속기제어장치(10)는 내부 프로그램에 의해 자동변속기 시스템의 정상동작 및 비정상동작을 판단하여 그 정상동작 여부에 따라 상기 주차표시램프 Lp를 구동하는 구동신호 SL의 동작 모우드를 변화시킨다. 램프구동신호의 동작모우드는 온상태 또는 오프상태로부터 일정주기로 반복되는 온/오프상태로 변화한다. 일정주기로 온/오프 반복되는 램프구동신호는 상기 변속기제어장치(10)에 내장된 통상의 쌍안정 멀티바이브레이터 회로로 구성된 타이머를 통해 발생된다.To this end, the transmission control device 10 determines the normal operation and abnormal operation of the automatic transmission system by an internal program, and changes the operation mode of the driving signal SL for driving the parking display lamp Lp according to the normal operation. The operation mode of the ramp drive signal changes from the on state or the off state to the on / off state which is repeated at regular intervals. The ramp drive signal, which is repeatedly turned on and off at a predetermined period, is generated through a timer composed of a conventional bistable multivibrator circuit built in the transmission control apparatus 10.
변속기제어장치(10)에서 램프구동신호 SL의 동작 모우드를 변화시켜 자동변속시스템의 고장여부를 표시하는 방법에 대해 제2도의 플로우 챠트를 참고로 설명하면 다음과 같다.Referring to the flowchart of FIG. 2, the transmission control apparatus 10 changes the operation mode of the lamp driving signal SL to indicate whether the automatic transmission system is faulty.
단계 30에서, 엔진이 시동되어 있는지 확인하고 단계 31에서 자동변속기의 변속레버가 주차(P)위치에 있는 지를 판단한다. 변속레버가 주차위치에 있다면 단계 32에서 자동변속기시스템이 정상동작상태인지를 판단하고, 정상동작이면 단계 33으로 가서 램프구동신호 SL를 온 상태로 만들어 종전과 같이 주차표시램프 Lp를 점등시킨다. 반면에 시스템이 비정상상태에 있다면 단계 34에서 램프구동신호를 일정주지로 온/오프반복되는 신호로 발생되게 한다. 이에 의해 주차표시램프 Lp는 일정주기로 점멸동작을 계속하게 된다.In step 30, it is checked whether the engine is started, and in step 31 it is determined whether the shift lever of the automatic transmission is in the parking (P) position. If the shift lever is in the parking position, it is determined in step 32 whether the automatic transmission system is in normal operation. If the shift lever is in normal operation, the control unit proceeds to step 33 to turn on the lamp driving signal SL and turns on the parking indication lamp Lp as before. On the other hand, if the system is in an abnormal state, in step 34, the lamp driving signal is generated as a signal that is repeatedly turned on / off at a predetermined time. As a result, the parking indication lamp Lp continues to blink.
한편, 인히비터 스위치가 P위치에 있지 않다면 단계 35로 가서 또다시 시스템의 정상여부를 판단하며, 시스템이 비정상일때 단계 34에서의 램프구동신호 온/오프 반복동작을 수행하게 만들고, 정상동작상태일때는 단계 36에서 램프구동신호 SL를 오프 상태로 만든다. 이에 의해 주차표시램프는 종전과같이 꺼져있게 된다.On the other hand, if the inhibitor switch is not in the P position, go to step 35 again to determine whether the system is normal, and when the system is abnormal, perform the ramp drive signal on / off repeat operation in step 34, and in the normal operation state. Turns off the lamp drive signal SL in step 36. As a result, the parking indication lamp is turned off as before.
이상 설명한 바와 같이, 본 발명에 의하면 자동변속기시스템의 고장여부를 주차표시램프의 점멸동작에 의해 나타낼 수 있으므로 자동변속기의 고장상태를 운전자에게 즉각적으로 알려주어 빠른시간내에 수리 조치를 취할 수 있는 이점이 있다.As described above, according to the present invention, the failure of the automatic transmission system can be indicated by the blinking operation of the parking indicator lamp, so that the driver can be notified immediately of the failure state of the automatic transmission, so that repair measures can be taken in a short time. have.
