본 발명은 차량속도 급감속시 비상등 제어장치에 관한 것으로, 특히 일정한 속도 이상의 주행 차량이 설정된 레벨이하로 급감속할 때 비상등을 점등시켜 후방 차량에게 경고하여 줌과 아울러 에어콘을 자동으로 오프시켜 브레이크 기능을 향상시켜 돌발적인 사고로 인한 피해를 최소화 하고자 한 차량속도 급감속시 비상등 제어장치에 관한 것이다.The present invention relates to an emergency light control device during a sudden deceleration of a vehicle speed, in particular, when a driving vehicle of a predetermined speed or more rapidly decelerates below a set level, the emergency light is turned on to warn the rear vehicle and to automatically turn off the air conditioner to provide a brake function. Emergency light control device in case of sudden speed reduction of vehicle to improve damage to minimize accidental accident.
종래의 차량에 있어서는 주행중 전방의 돌발 사태등으로 운전자가 급브레이크를 밟으면 브레이크등은 자동으로 점등되나 비상등은 점멸하지 않아 비상등을 점멸시키기 위하여는 운전자가 별도로 비상등 스위치를 눌러주어야 했다. 즉, 운전자가 전방의 돌발적인 상황으로 인해 급제동을 하여 전방의 상황은 신속히 대처하여도 비상등 스위치를 신속히 조작하지 못하게 되면 후방 차량은 전방의 상황에 대한 대처 능력이 저하됨으로 인한 2차적인 충돌을 일으킬 문제점이 있었다.In a conventional vehicle, the brake light is automatically turned on when the driver presses a sudden brake due to an emergency flashlight while driving, but the emergency light does not blink, and the driver has to press the emergency light switch separately to blink the emergency light. In other words, if the driver suddenly brakes due to an accidental situation in the front, and the emergency light switch cannot be operated quickly even though the situation in front of the vehicle is quickly dealt with, the rear vehicle may cause a secondary collision due to a decrease in the ability to cope with the situation in front of the vehicle. There was a problem.
또한, 종래 차량이 에어콘을 가동한 상태에서 주행중에 전방의 급작스러운 상황으로 인해 신속히 브레이크 페달을 밟아도 브레이크 진공이 감소된 상태라 제동거리가 길어지게 되어 차량의 사고가 발생되는 문제점이 있었다.In addition, the conventional vehicle has a problem that the braking distance is long because the brake vacuum is reduced even when the brake pedal is rapidly pressed due to a sudden situation in front of the vehicle while driving the air conditioner, thereby causing an accident of the vehicle.
이에 본 발명은 이와 같은 종래의 문제점들을 해결하기 위하여 안출한 것으로 차량속도 급감속시 비상등을 임의 제어하여 후방 차량에 경고하여 줌으로써 2차 충돌을 방지하고, 또한 에어콘을 임의 제어하여 브레이크 기능을 향상시켜 돌발적인 상황을 신속히 대처할 수 있도록 한 차량속도 급감속시 비상등 제어장치를 제공하는데 그목적이 있다.Accordingly, the present invention has been made in order to solve such a conventional problem to prevent secondary collision by arbitrarily controlling the emergency light to warn the rear vehicle during sudden deceleration of the vehicle speed, and also to improve the brake function by arbitrarily controlling the air conditioner. Its purpose is to provide emergency light control devices for rapid deceleration of vehicle speeds that enable rapid response to unexpected situations.
이와 같은 목적을 달성하기 위한 본 발명은 차량속도를 감지하는 차량속도 감지센서와, 에어콘의 동작을 제어하기 위한 에어콘 온/오프 스위치와, 가변저항으로 이루어진 센시티비티(Sensitivity) 감지센서와, 상기 센서들과 스위치 상태를 인식하여 해당되는 제어신호를 출력시키는 마이컴과, 상기 마이컴의 제어에 따라 점등되거나 소등되는 비상등과, 상기 마이컴의 제어에 따라 동작하는 에어콘을 포함하여 구성함을 특징으로 한다.The present invention for achieving the above object is a vehicle speed sensor for detecting the vehicle speed, an air conditioner on / off switch for controlling the operation of the air conditioner, a sensitivity sensor (sensitivity) consisting of a variable resistor, and Micom for recognizing the state of the sensor and the switch and outputs a corresponding control signal, an emergency light that is turned on or off under the control of the micom, and an air conditioner operating under the control of the micom.
이하, 본 발명의 실시예를 첨부된 도면을 참고로 하여 상세히 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 발명의 블럭도로서 주행중인 차량속도를 감지하는 차량속도 감지센서(10)와, 이 차량속도 감지센서(10)로부터 출력되는 차량속도의 가감치를 감지하는 센시티비티스위치(30)와, 에어콘의 동작을 제어하기 위한 에어콘 온/오프 스위치(20)와, 상기 차량속도 감지센서(10) 및 센시티비티 감지센서(30)로부터 감지된 신호와 에어콘 온/오프 스위치(20)의 상태에 따라 제어 신호를 출력시키는 마이컴(40)과, 이 마이컴(40)의 제어 신호에 따라 점등 또는 소등되는 비상등(50)과, 상기 마이컴(40)의 제어 신호에 따라 동작하는 에어콘(60)으로 구성된 것이다.1 is a block diagram of the present invention, the vehicle speed sensor 10 for detecting a running vehicle speed, and the sensitivity switch 30 for detecting the acceleration and decrease of the vehicle speed output from the vehicle speed sensor 10. And, the air conditioner on / off switch 20 for controlling the operation of the air conditioner, the signal detected from the vehicle speed sensor 10 and the sensitivity detection sensor 30 and the air conditioner on / off switch 20 The microcomputer 40 which outputs a control signal according to the state, the emergency light 50 which is turned on or off according to the control signal of the microcomputer 40, and the air conditioner 60 which operates according to the control signal of the microcomputer 40. It is composed of.
단, 상기 마이컴(40)에는 수온센서, 드로틀센서의 신호와 비상등 온신호등이 더 입력될 수 있으며, 또한, 마이컴(40)의 출력신호로 인젝터(Injector)와 스파크 제어등이 가능하다.However, the signal of the temperature sensor, the throttle sensor and the emergency light ON signal may be further input to the microcomputer 40, and an injector and a spark control may be performed as the output signal of the microcomputer 40.
한편, 이와 같은 구성으로 이루어진 본 발명의 동작을 첨부된 도면에 의해 자세히 설명하면 다음과 같다.On the other hand, the operation of the present invention having such a configuration will be described in detail by the accompanying drawings as follows.
먼저, 차량이 주행중에는 차량속도 감지센서(10)로부터는 속도에 의해 감지된 신호가 마이컴(40)으로 입력된다.First, while the vehicle is driving, a signal sensed by the speed is input to the microcomputer 40 from the vehicle speed sensor 10.
또한, 사용자가 주행중에 에어콘 온/오프 스위치(20)를 온 상태로 하면 상기 마이컴(40)의 제어신호에 따라 에어콘(40)은 가동되는 것이다.In addition, when the user turns on the air conditioner on / off switch 20 while driving, the air conditioner 40 is operated according to the control signal of the microcomputer 40.
한편, 상기 마이컴(40)의 램(RAM)에는 제3도에 도시된 바와 같이 차량속도에 따른 차량속도 한계치가 메모리되어 있으며, 여기서 K10∼K200의 한계치는 시험치 값으로, 이러한 한계치는 센시티비티 감지센서(30)의 조정에 따른 입력값에 의해 변경된다.Meanwhile, as shown in FIG. 3, the RAM of the microcomputer 40 stores a vehicle speed limit value according to the vehicle speed, wherein the limit values of K10 to K200 are test values, and these limits are sentimetric values. It is changed by the input value according to the adjustment of the beat sensor 30.
즉, 상기 센시티비티 감지센서(30)는 가변저항으로 되어 있어 사용자가 일정한 한계치를 설정한 상태에서 운전자가 브레이크 페달을 밟음에 따라 급감속되는 속도차 그 한계치 이상이면 상기 마이컴(40)은 센시티비티 감지센서(30)로 일정한 신호를 입력받게 되는 것이다.That is, the sensitivity sensor 30 is made of a variable resistor so that when the user presses the brake pedal in a state where the user sets a certain threshold value, the microcomputer 40 senses a speed difference that is greater than or equal to the threshold value. The city signal will be received a certain signal to the sensor (30).
그러므로 차량속도가 빠른 상태에서 운전자가 급브레이크를 밟으면 마이컴(40)에서는 이를 감지하여 비상등(50)을 점멸시키도록 제어함과 동시에 에어콘 온/오프 스위치(20) 상태를 감지하는데 이때 에어콘(60)이 가동중이라면 에어콘(60) 작동이 중지되도록 제어함으로써 브레이크 진공을 증가시켜 제동거리를 줄일수 있다.Therefore, when the driver presses a sudden brake in a state in which the vehicle speed is high, the microcomputer 40 detects this and controls the flashing of the emergency light 50 and at the same time detects the air conditioner on / off switch 20 state. If the air conditioner 60 is in operation during this operation, the brake vacuum can be increased to reduce the braking distance.
그리고 제2도는 비상등 제어의 타이밍 챠트로서 (a)는 비상등 턴온 비트, (b)는 비상등 제어신호, (c)는 비상등 상태, (d)는 에어콘 상태 및 (e)는 운전자의 임의적인 비상등 온신호를 각각 도시한 타이밍 챠트이다.2 is a timing chart of emergency light control, in which (a) is an emergency light turn-on bit, (b) is an emergency light control signal, (c) is an emergency light state, (d) is an air conditioner, and (e) is a driver's arbitrary emergency light on. A timing chart showing the signals, respectively.
이하, 상기 마이컴(40)의 제어동작을 플로우 챠트인 제4도와 타이밍 챠트인 제2도를 참고로 하여 설명한다.Hereinafter, the control operation of the microcomputer 40 will be described with reference to FIG. 4 as a flowchart and FIG. 2 as a timing chart.
즉, 마이컴(40)에서는 차량속도 감지센서(10)로부터의 차량속도와 센시티비티 감지센서(30)로부터의 센시티비티를 입력받고(S1 단계) 비상등 턴온 비트(Bit)가 '1'(하이레벨)인가를 판별한다(S2단계).That is, the microcomputer 40 receives the vehicle speed from the vehicle speed sensor 10 and the sensitivity from the sensitivity sensor 30 (step S1), and the emergency light turn-on bit Bit is set to '1' ( High level) (step S2).
만일, 상기 S2단계에서 비상등 턴온 비트가 '1'로 판별되면 비상등 온신호가 '1'인가를 판별하게 된다(S3 단계).If it is determined in step S2 that the emergency light turn-on bit is '1', it is determined whether the emergency light on signal is '1' (step S3).
이때, 이 S3 단계에서 비상등 턴온 비트가 '1'이 아니면 차량속도가 눈금값(Calibration Value; 이를 al이라 한다)보다 큰가를 판별하게 된다(S4 단계).At this time, if the emergency light turn-on bit is not '1' in step S3, it is determined whether the vehicle speed is greater than a calibration value (also referred to as al) (step S4).
여기서 눈금값(al)은 차량속도의 한계치를 설정하게 된 것으로 보통 주행속도가 80km/h으로 설정한다.Here, the scale value (al) is to set the limit of the vehicle speed, the normal running speed is set to 80km / h.
즉, S3단계에서 판별한 결과 현재 차량의 속도가 눈금값을 초과하게 되면 현재 입력되는 차량속도가 급감속되는 속도를 측정하게 된다(S10 단계).That is, when the speed of the current vehicle exceeds the scale value as a result of the determination in step S3, the speed at which the currently input vehicle speed is rapidly reduced is measured (step S10).
한편, 상기 S3 단계에서 비상등 온신호가 '1'로 판단되면 비상등 턴온 비트가 '1'인 상태에서 비상등(50)을 제어한다(S5, S6단계). 그리고 S6단계에서는 에어콘 온스위치가 '1'(작동중)인가를 판별하여 동작중이면 에어콘을 오프시키게 된다(S7, S8 단계).On the other hand, if it is determined that the emergency light ON signal is '1' in step S3, the emergency light 50 is controlled in a state where the emergency light turn-on bit is '1' (steps S5 and S6). In operation S6, the air conditioner switch is determined to be '1' (operation), and the air conditioner is turned off when the operation is performed (steps S7 and S8).
한편, S10단계에서 판별한 결과 현재 차량의 속도 감속으로 인한 감속차가 설정된 임계치보다 크다고 판별되면 비상등 턴온 시간 지연이 눈금값(a2)보다 큰가를 판별하게 된다(S12 단계).On the other hand, if it is determined in step S10 that the deceleration difference due to the current vehicle speed reduction is greater than the set threshold value, it is determined whether the emergency light turn-on time delay is greater than the scale value a2 (step S12).
그러면 상기 S12 단계에서 비상등 턴온 시간 지연이 눈금값(a2)보다 크면 S5 단계부터 S8 단계를 차례로 수행하게 된다.Then, if the emergency light turn-on time delay is greater than the scale value a2 in step S12, steps S5 to S8 are sequentially performed.
또한, 상기 S12 단계에서 판별한 결과 비상등 턴온 시간지연이 눈금값보다 작은 것으로 판별되면 타임지연 = 타임지연+1 을 수행하고 완료한다(S14 단계).In addition, if it is determined in step S12 that the emergency light turn-on time delay is smaller than the scale value, time delay = time delay + 1 is performed and is completed (step S14).
또한, 상기 S4 단계에서 판별한 결과 차량속도가 눈금값(al)보다 작으면, 비상등 턴온 비트=0이고, 비상등=0이 된다(S15 단계).If the vehicle speed is smaller than the scale value al as a result of the determination in step S4, the emergency light turn-on bit = 0 and the emergency light = 0 (step S15).
그러므로 이 S15 단계 이후에는 에어콘 온스위치가 '1'인가를 판별하여 '1'이면 에어콘을 온하고, '1'이 아니면 완료한다(S16∼S17 단계).Therefore, after this step S15, it is determined whether the air conditioner on switch is '1', and if it is '1', the air conditioner is turned on, and if it is not '1', the process is completed (steps S16 to S17).
한편, 상기 S3 단계에서 비상등 온신호가 '1'이 아니면, 즉 비상등이 소등되어 있는 상태이면, 상기 S4 단계를 수행단계로 진행하게 된다.On the other hand, if the emergency light on signal is not '1' in the step S3, that is, the emergency light is turned off, the step S4 proceeds to the execution step.
이상에서 설명한 바와 같은 본 발명은 차량의 급감속시 현재의 차량속도에 따른 가·감속 차량속도 임계치에 따라 비상등(50)과 운전자가 임의로 비상등 점등의 센시티비티를 조정함으로써 사고를 미연에 방지할 수 있으며 에어콘의 중단에 따라 제동거리를 단축시킬 수 있는 효과가 있다.As described above, according to the present invention, the emergency light 50 and the driver may arbitrarily adjust the sensitivity of the emergency light on according to the acceleration / deceleration vehicle speed threshold according to the current vehicle speed when the vehicle suddenly decelerates to prevent an accident. It is possible to reduce the braking distance in accordance with the air conditioning stop.
