본고안은 앤티록제동시스템의 ABS경고등제어포트고장검출장치에 관한 것으로서, 더욱 상세히는 자동제동시스템(A.B.S)에서 ABS경고등의 고장을 검출하는 방법에 관한 것이다.This paper relates to the ABS warning light control port fault detection device of the anti-lock braking system, and more particularly, to a method of detecting a failure of the ABS warning light in the automatic braking system (A.B.S).
자동차의 자동제동시스템(A.B.S)의 경우, 제동장치의 센서로부터의 신호에 의하여 자동제동상태의 불능을 운전자에게 고지하는 ABS경고등이 장착되고, 이 ABS경고등은 앤티록동작에 이상이 발생하는 경우 운전자에게 이의 점검을 미리할 수 있도록 고지하는 목적으로 사용된다.In the case of an automatic braking system (ABS) of an automobile, an ABS warning lamp is provided to notify the driver of the inability to brake automatically by a signal from the sensor of the brake device. It is used for the purpose of notifying the user in advance of the inspection.
그러나 이러한 ABS경고등에 있어서, 출력포트의 이상이나 단선등의 고장이 발생한 경우, 운전자는 이러한 자동제동시스템의 고장을 감지하지 못하고 주행하게 됨으로서 통상적인 자동제동모우드로 수행하는 운전조작을 하게 되어 제동작동시에 사고를 유발하게 되는 문제점이 있었다.However, in the case of ABS warning, if the output port is abnormal or breakage occurs, the driver does not detect the failure of the automatic braking system and runs the vehicle to operate with the normal automatic braking mode. At the same time there was a problem that caused an accident.
상기의 문제점을 감안하여 본고안의 앤티록제동시스템의 ABS경고등제어포트고장검출장치는 ABS경고등의 고장을 사전에 감지할 수 있게 하여 교통사고를 예방할 수 있도록 하는 장치에 관한 것이다.In view of the above problems, the ABS warning light control port fault detection device of the anti-lock braking system of the present disclosure relates to a device which can prevent a traffic accident by detecting a failure of an ABS warning light in advance.
이하의 부수된 도면과 함께 종래의 앤티록제동시스템의 ABS경고등제어포트고장검출장치의 문제점과 함께 본고안의 앤티록제동시스템의 ABS경고등제어포트고장검출장치를 더욱 상세하게 설명한다.The ABS warning light control port failure detection device of the anti-lock braking system of the present invention will be described in more detail together with the problems of the ABS warning light control port failure detection device of the conventional anti-lock braking system together with the accompanying drawings.
제1도는 본 고안의 앤티록제동시스템의 ABS경고등제어포트고장검출장치를 구현하는 장치의 일실시예를 도시하는 블록다이아그램도, 제2도는 본 고안의 앤티록제동시스템의 ABS경고등제어포트고장검출장치를 도시하는 플로우챠트이다.1 is a block diagram showing an embodiment of a device for implementing the ABS warning light control port failure detection device of the anti-lock braking system of the present invention, Figure 2 is a ABS warning light control port failure of the anti-lock braking system of the present invention It is a flowchart which shows a detection apparatus.
제2도는 본고안의 앤티록제동시스템의 ABS경고등제어포트고장검출장치를 구현하는 장치의 일실시예를 도시하는 블록다이아그램도에서와 같이, 밧데리(1)와 연결된 점화스위치(2)와 마이컴입력전원부(3), 마이컴(5) 및 ABS경고등(4)을 구동하는 ABS경고등드라이버(10)로 구성되고 상기의 마이컴입력전원부(3)와 ABS경고등드라이버(10)의 마이컴(5)으로의 입력포트부 사이에 AND 논리소자(9)를 더 구비한다.2 is a block diagram showing an embodiment of an apparatus for implementing an ABS warning light control port fault detection device of the anti-lock braking system of the present invention, the ignition switch (2) connected to the battery (1) and the microcomputer input It is composed of an ABS warning light driver 10 for driving the power supply unit 3, the microcomputer 5, and the ABS warning light 4, and the input of the microcomputer input power supply 3 and the ABS warning light driver 10 to the microcomputer 5 of the above. An AND logic element 9 is further provided between the port portions.
20은 디스플레이및 고장알람수단이다. AND 논리소자(9)를 구비하고 상기 논리값이 인가되는 포트인 고장검출포트(8)및 리셋포트(6)를 마이컴(5)에 구비하는 것이다.20 is a display and fault alarm means. The microcomputer 5 includes a fault detection port 8 and a reset port 6 which are provided with an AND logic element 9 and to which the logic value is applied.
상기의 구성에서 마이컴(5)의 ABS경고등드라이버제어출력포트(7)가 고장인 경우, ABS경고등드라이버(10)는 작동하지 않으며 따라서 ABS경고등(4)은 작동할 수 없다.In the above configuration, when the ABS warning light driver control output port 7 of the microcomputer 5 is malfunctioning, the ABS warning light driver 10 does not operate and therefore the ABS warning light 4 cannot operate.
ABS경고등드라이버제어포트(7)의 고장을 검출하기 위하여 점화스위치(2)가 ON 된후에 리셋되어서 마이컴(5)이 구동되면 리셋신호와 ABS경고등드라이버제어 출력포트(7)의 AND 논리연산에 의하여 만일 ABS경고등드라이버제어축력포트(7)및 배선의 고장이 있으면 그 논리값이 고장검출입력포트(8)로 입력되어 출력포트의 고장검출이 가능하게 한다.If the microcomputer 5 is driven after the ignition switch 2 is turned on to detect a failure of the ABS warning light driver control port 7, and the microcomputer 5 is driven, the reset signal and the AND logic operation of the ABS warning light driver control output port 7 are performed. If there is a failure of the driver control axial force port 7 and the wiring of the ABS warning light, the logic value is input to the fault detection input port 8 to enable fault detection of the output port.
상기의 고장검출포트(8)로 부터의 신호입력에 의한 디스플레이 및 자가고장경보장치는 통상적인 마이컴의 소프트웨어로서 처리할 수 있을 것이고 이러한 소프트웨어적인 처리의 일예가 제2도에 도시된다.The display and self-failure alarm device by the signal input from the fault detection port 8 can be processed as software of a conventional microcomputer, and an example of such software processing is shown in FIG.
점화스위치(2)가 ON 되어(30) 리세(31)값이 HIGH이고, ABS경고등드라이버제어신호가 HIGH (즉, 드라이버구성요소의 단선, 단락 등에 의하여 전압이 비정상적으로 인가되는 상태이면; '32')이면, ABS경고등드라이버제어출력포트(7)가 고장임을 감지(33)하여 신호는 고장검출포트(8)로 인가되고, 만일 ABS경고등드라이버신호가 LOW (정상상태)이면, AND 논리회로에 의하여 자동제동장치의 진단이 종료(40)되어 마이컴(5) 구동의 정상모우드로 진입하는 것이다.If the ignition switch 2 is turned ON (30) and the reset 31 value is HIGH, and the ABS warning light driver control signal is HIGH (i.e., a voltage is abnormally applied due to disconnection, short circuit, etc. of the driver component; '), The ABS warning light driver control output port 7 is detected as fault 33 and the signal is applied to the fault detection port 8, and if the ABS warning light driver signal is LOW (normal state), the AND logic circuit By the end of the diagnosis of the automatic braking device 40 is to enter the normal mode of driving the microcomputer (5).
이상과 같은 본고안의 앤티록제동시스템의 ABS경고등제어포트고장검출장치는 마이컴의 입력단에 ABS경고등과 배설되는 회로상에 AND 논리소자를 더 구비함으로서 ABS경고등의 고장을 검출할 수있게 하여 ABS경고등의 고장을 사전에 고지함으로서 앤티록제동모우드의 오인식에 의한 사고를 방지할 수 있게 하는 유용한 고안인 것이다.As described above, the ABS warning light control port fault detection device of the anti-lock braking system of the present invention further includes an AND logic element on the circuit provided with the ABS warning light at the input terminal of the microcomputer to detect the failure of the ABS warning light. It is a useful design that prevents accidents caused by the anti-lock braking mode by notifying the failure in advance.
