본 고안은 자동차의 자동악셀레이터용 전자제어안전장치에 관한 것으로 특히, 자동악셀레이터에 의한 자동 운전시 앞차와의 거리를 검출하고 그 검출된 감지신호를 비교판단하여 동작제어 신호를 발생시키도록 됨으로써, 이 동작제어신호에 의해 자동으로 액튜레이터를 제어하도록 함으로 차량의 충돌사고를 방지할 수 있도록 된 자동차의 자동악셀레이터용 전자제어 안전장치에 관한 것이다.The present invention relates to an electronic control safety device for an automatic accelerator of an automobile, and in particular, by detecting the distance from the vehicle in front of the automatic accelerator by an automatic accelerator and comparing the detected detection signals to generate an operation control signal. The present invention relates to an electronic control safety device for an automatic accelerator of a vehicle that can prevent an accident of a vehicle by automatically controlling an actuator by an operation control signal.
종래의 자동악셀레이터 회로는 제1도에 도시된 바와 같이 가속상태설정, 예컨데 가속상태를 반자동 혹은 자동으로 설정하여 그에 따른 스위칭 제어신호를 발생시키는 스위칭구동부(70)와, 이 스위칭 구동부(70)이 스위칭 제어신호에 의해 자동액튜레이터장치(71)을 제어하는 스위칭제어부(72)로 이루어져 있다.In the conventional automatic accelerator circuit, as shown in FIG. 1, a switching driver 70 for setting an acceleration state, for example, an acceleration state semi-automatically or automatically and generating a switching control signal accordingly, and the switching driver 70 It consists of a switching control part 72 which controls the automatic actuator apparatus 71 by a switching control signal.
그리고, 상기 스위칭 구동부(70)에는 가속상태 예컨데 자동 혹은 반자동의 상태를 설정해 주는 메인스위칭(73)와, 이 메인스위칭(73)의 일단에 다이오드(D1)를 거쳐 연결되고 반 자동치 턴온/오프 되면서 스위칭제어신호를 발생시키는 보조스위치(74)와, 그리고 상기 메인스위치(73)의 자동 혹은 반자동 설정 상태를 외부로 표시하는 다이오드(PD1, PD2)로 이루어져 있고, 상기 스위칭제어부(72)에는 상기 스위칭구동부(70)으로부터 입력되는 스위칭제어신호에 의해 액튜레이터장치(71)를 제어하는 릴레이(75)와, 이 릴레이(75)의 코일에 연결되어 코일에 동작전류를 단속하는 트랜지스터(TR)등으로 구성되어 있다.In addition, the switching driver 70 is connected to the main switching 73 for setting an acceleration state, for example, an automatic or semi-automatic state, and one end of the main switching 73 via a diode D 1 , and the semi-automatic turn-on / And an auxiliary switch 74 which generates a switching control signal while being turned off, and diodes PD 1 and PD 2 which display an automatic or semi-automatic setting state of the main switch 73 to the outside. ) Includes a relay 75 for controlling the actuator device 71 by a switching control signal input from the switching driver 70, and a transistor connected to a coil of the relay 75 to control an operating current to the coil ( TR).
여기서, 상기 메인스위치(73)의 일단에는 전원 즉, 배터리(76)가 연결되어 있고, 상기 트랜지스터(TR)의 베이스단에도 스위치(77)가 연결되어 있다.Here, a power supply, that is, a battery 76 is connected to one end of the main switch 73, and a switch 77 is also connected to the base end of the transistor TR.
한편, 상기와 같은 구성으로 된 종래 자동악셀레이터회로의 동작을 살펴보면, 먼저 운전자가 차량운전중에 가속페달을 눌러준 상태에서 계속 정속운행할 경우 스위칭구동부(70)의 메인스위치(73)를 설정하여 자동 혹은 반자동상태로 설정시키게 된다.On the other hand, looking at the operation of the conventional automatic accelerator circuit having the configuration as described above, if the driver continues to operate at a constant speed while the driver pressed the accelerator pedal during driving of the vehicle first by setting the main switch 73 of the switching driver 70 automatically Or set to semi-automatic state.
예컨데, 메인스위치(73)를 반자동 위치에 놓았을 경우 운전자가 악셀레이터페달에서 발을 옮겨 보조 휴식판에 놓게 되면 이 운전자의 발의 무게로 인하여 보조스위치(74)가 턴온되게 된다. 이때 스위치(77)가 on 상태에 있으므로 트랜지스터(TR)가 턴온되게 된다.For example, when the main switch 73 is placed in the semi-automatic position, when the driver moves the foot from the accelerator pedal to the auxiliary rest plate, the auxiliary switch 74 is turned on due to the weight of the driver's foot. At this time, since the switch 77 is in the on state, the transistor TR is turned on.
따라서, 상기 배터리(76)의 구동전압 즉, 스위칭제어신호가 메인스위치(73)의 반자동접점(CD)과 다이오드(D1) 그리고 보조스위치(74)를 통해 릴레이(75) 코일에 입력됨으로 릴레이(75)접점이 턴온되어 자동액튜레이터(71)에 스위칭제어신호를 전달하게 된다. 그러므로 자동액튜레이터(74)가 동작되어 악셀레이터를 계속 가속하게 된다. 또한 운전자가 발을 보조휴식판에서 띠게 되면 보조스위치(74)가 턴오프되게 되어 상기 동액튜레이터(71)에 전원이 차단되게 됨으로 현 기계식으로 악셀레이터를 구동하게 된다.Accordingly, the driving voltage of the battery 76, that is, the switching control signal is input to the coil of the relay 75 through the semi-automatic contact CD, the diode D 1 and the auxiliary switch 74 of the main switch 73. The contact point 75 is turned on to transmit a switching control signal to the auto actuator 71. Therefore, the auto actuator 74 is operated to continuously accelerate the accelerator. In addition, when the driver puts his foot on the auxiliary rest plate, the auxiliary switch 74 is turned off, and the power is cut off from the copper actuator 71, thereby driving the accelerator in the present mechanical manner.
그리고, 상기와 같은 구성으로 된 종래 자동 악셀레이터회로는 수동소자로 이루어진 회로이기 때문에 정밀한 제어동작을 수행할 수가 없었음은 물론 고속운전시 운전자의 전방주시태만으로 앞차량과의 거리가 너무 가깝게 될 경우 자동운전해제 기능과 이를 경보할 기능이 구비되어 있지 않으므로 차량안전사고의 위험성이 증대되는 문제점이 있었다.In addition, since the conventional automatic accelerator circuit having the above-described configuration is a circuit composed of passive elements, the precise control operation cannot be performed and the distance from the front vehicle becomes too close only by the driver's front peripheral state at high speed. There is a problem that the risk of a vehicle safety accident is increased because it is not equipped with the automatic driving release function and the alarm function.
이에 본 고안은 상기와 같은 문제점을 해결하기 위하 안출된 것으로, 자동악셀레이터에 의한 자동운전시 앞차와의 거리를 검출하고 그 검출된 감지신호를 비교판단하여 동작제어신호를 발생시키도록 됨으로써, 이 동작제어신호에 자동으로 액튜레이터를 제어하도록 됨으로 차량의 충돌사고를 방지할 수 있도록 됨은 물론 차간거리가 일정거리 이내일 경우는 경보신호를 발생되게 됨으로 이로 인해 운전자가 경각심을 갖게 되어 운전부주위로 인한 안전사고를 미연에 방지할 수 있도록 된 자동차의 자동악셀레이터용 전자 제어 안전장치를 제공함에 그 목적이 있다.In order to solve the above problems, the present invention is designed to detect a distance to the vehicle in front of an auto accelerator by an automatic accelerator and to generate an operation control signal by comparing and detecting the detected detection signal. By controlling the actuator automatically to the control signal, it is possible not only to prevent the collision of the vehicle but also to generate an alarm signal when the distance between the cars is within a certain distance. It is an object of the present invention to provide an electronically controlled safety device for an auto accelerator of an automobile that can prevent an accident in advance.

An A / D converter 2 for converting an input analog handle position detection signal into a digital signal, a handle rotation angle detection signal input from the A / D converter 2, and a detection signal input from various sensors The microcomputer 30 for comparing and judging according to the built-in program and controlling the automatic accelerator system, and the inter-vehicle distance sensor 4 for transmitting the detection signal of detecting the distance between the microcomputer 3 and the microcomputer 3) OR gate 5 for generating an output signal by logically combining the brake or clutch pedal operation signal, and a buzzer driving circuit unit 6 for generating an alarm sound by the operation control signal of the microcomputer 3; have.
그리고, 상기 마이컴(3)에는 가속상태 예컨데 자동 혹은 반자동의 상태를 설정해주는 메인스위치(7)가 연결되어 있고, 상기 마이컴(3)의 구동제어신호에 따라 자동액튜레이터(8)를 제어하는 자동악셀레이터 구동회로부(9)가 마이컴(3)에 연결되어 있다.The microcomputer 3 is connected to a main switch 7 for setting an acceleration state, for example, an automatic or semi-automatic state, and automatically controls the auto actuator 8 according to a drive control signal of the microcomputer 3.

The clutch detection sensor 11 is connected, and the buzzer 13 is connected to one end of the buzzer driving circuit unit 12.
다음에는 상기와 같은 구성으로 된 본 고안의 작용효과를 설명한다.Next will be described the effect of the present invention made of the configuration as described above.
본 고안의 동작은 제2도, 제3도에 도시된 바와같이 먼저 운전자가 차량운전중에 가속페달을 눌러준 상태에서 계속 정속운행하는 경우 메인스위치(7)의 노브를 돌려 자동 혹는 반자동을 설정해주게 된다.In the operation of the present invention, as shown in FIGS. 2 and 3, if the driver continues to operate at constant speed while the driver presses the accelerator pedal while driving the vehicle, turn the knob of the main switch 7 to set automatic or semi-automatic operation. do.
예컨데, 메인스위치(7)를 반자동위치에 놓았을 경우 운전자가 악셀레이터페달에서 발을 보조휴식판에 옮겨 놓으면서 정가속운전을 계속할 수 있도록 자동악셀레이터구동회로부(9)가 반자동으로 자동액튜레이터(8)를 단속하게 되고, 상기 메인스위치(7)가 자동위치에 놓였을 경우는 상기 동작에 관계없이 설정된 속도로 정가속되게 상기 자동악셀레이터구동회로부(9)가 자동으로 자동액튜레이터(8)를 단속하게 된다.For example, when the main switch 7 is placed in the semi-automatic position, the automatic accelerator driving circuit section 9 automatically semi-automatically operates the accelerator 8 so that the driver can continue the acceleration operation while moving the foot on the auxiliary rest plate from the accelerator pedal. When the main switch (7) is in the automatic position, the automatic accelerator driving circuit unit (9) automatically interrupts the automatic actuator (8) so as to be accelerated at a predetermined speed regardless of the operation. .
이때, 각 센서들(1, 4)을 통해 차단거리, 핸들회전각 등등을 마이컴(3)이 체킹하게 된다.At this time, the microcomputer 3 checks the blocking distance, the handle rotation angle, and the like through the sensors 1 and 4.
즉, 마이컴(3)이 초기화하고 현재 메인스위치(7)가 반자동위치에 설정되어 있는지를 판단하게 된다.That is, the microcomputer 3 initializes and determines whether the main switch 7 is currently set to the semi-automatic position.
그리고, 상기 단계에서 판단한 결과 메인스위치(7)에 반자동위치가 설정되어 있을 경우는 다음 단계로 진행하여 핸들의 회전각을 기준각 X보다 큰지를 판단하게 되고, 상기 판단하는 단계중에 메인스위치(7)가 반자동의 위치에 설정되어 있지 않을 경우는 전자동의 위치에 설정된 것이므로 다음 단계로 진행하여 자동악셀레이터 구동회로부(9)를 통해 자동 액튜레이터(8)를 전자동구동시키게 된다.When the semi-automatic position is set in the main switch 7 as a result of the determination in the above step, it is determined that the rotation angle of the handle is greater than the reference angle X, and the main switch 7 during the determination step. If is not set to the semi-automatic position is set to the fully automatic position and proceeds to the next step to automatically drive the automatic actuator 8 through the automatic accelerator driving circuit section (9).
또한, 다음 단계에서 차간거리감지센서(4)를 통해 입력되는 차간거리 검출데이터를 기준값 H(차량간 최소 안전거리)와 비교판단하게 되고 그 판단결과 차간거리 검출데이타가 기준값 H보다 클 경우 즉, 차량이 앞차와 적정거리를 유지하고 있을 경우는 상기 핸들위치 판단단계로 진행한다. 그리고 상기 차단거리 판단단계 에서 판단한 결과 차간거리 검출데이터가 기준값 H 보다 작을 경우 즉, 차량이 앞차와의 안전거리 이내에 있을 경우는 다음 단계로 진행하여 부저구동회로부(12)를 통해 부저(13)를 울리게 한다.In addition, in the next step, the distance detection data inputted through the distance detection sensor 4 is compared with the reference value H (minimum safety distance between vehicles), and as a result, when the distance detection data is larger than the reference value H, If the vehicle maintains the proper distance with the vehicle ahead of the vehicle proceeds to the steering wheel position determination step. When the inter-vehicle distance detection data is smaller than the reference value H, that is, when the vehicle is within a safe distance from the vehicle in front of the vehicle, the buzzer 13 is connected to the buzzer driving circuit unit 12. Let it ring
또한, 다음 단계로 진행하여 자동악셀레이터 구동회로부(9)를 통해 자동 액튜레이터(8)의 동작을 해제시킨다.Further, the process proceeds to the next step to release the operation of the auto actuator 8 through the auto accelerator driving circuit section 9.
그러므로, 운전자는 현재의 차량상태를 파악하여 적절한 조치를 취할 수 있게 된다.Therefore, the driver can grasp the current vehicle condition and take appropriate measures.
한편, 상기 핸들위치를 판단하는 단계중에 핸들회전각 감지센서(1)를 통해 검출한 핸들회전각 데이터가 기준값 X(회전허용범위 각)보다 작을 경우는 차량이 안전하게 운행할 수 있는 운전조건 상태이므로 설정된 자동·혹은 반자동으로 자동액튜레이터(8)를 계속동작시키고, 상기 판단결과 핸들회전각 데이터가 기준값 X보다 클 경우는 핸들이 좌측 혹은 후축으로 편향되어 안전운전에 지장이 있는 상태이므로 다음 단계로 진행하여 자동액튜레이터(8)의 동작을 해제시키게 된다.Meanwhile, when the steering wheel rotation angle data detected by the steering wheel rotation angle sensor 1 during the step of determining the steering wheel position is smaller than the reference value X (rotation allowable range angle), the vehicle is in a driving condition that can safely drive. The automatic actuator 8 is continuously operated automatically or semi-automatically, and if the steering wheel rotation angle data is larger than the reference value X as a result of the determination, the steering wheel is deflected to the left or the rear axle, thus preventing the safe operation. The operation of the auto actuator 8 is released.
한편, 상기 단계들이 진행되는 중에 OR게이트(5)로부터 "하이신호"가 입력될 경우 즉 운전자가 클러치페달 혹은 브레이크 페달을 밟을 경우는 인터럽트 루틴을 수행하여 자동액튜레이터(8)의 동작을 해제시키게 된다.On the other hand, when the "high signal" is input from the OR gate 5 during the above steps, that is, when the driver presses the clutch pedal or the brake pedal, an interrupt routine is performed to release the operation of the auto actuator 8. do.
이상 설명에서와 같이 본 고안은, 자동악셀레이터에 의한 자동운전시 앞차와의 거리를 검출하고, 그 검출한 감지신호를 비교판단하여 동작제어신호를 발생시키도록 됨으로써, 이 동작제어신호에 의해 자동으로 액튜레이터를 제어하도록 됨으로 차량의 충돌사고를 방지할 수 있도록 됨은 물론 차간거리가 일정거리 이내일 경우는 경보신호도 발생되게 됨으로 이로 인해 운전자가 경각심을 갖게 되어 운전부주위로 인한 안전사고를 미연에 방지할 수 있는 효과가 있다.As described above, the present invention detects the distance to the vehicle in front of the automatic accelerator by the automatic accelerator, and compares the detected detection signal to generate an operation control signal, thereby automatically generating the operation control signal. By controlling the actuator, it is possible not only to prevent the collision of the vehicle but also to generate an alarm signal when the distance is within a certain distance, which causes the driver to be alert and prevent the safety accident caused by the driving part. It can work.
