본 발명은 차량주행시에 타차량 및 장애물과의 충돌을 방지하기 위한 자동차의 자동 브레이크장치에 관한 것이다.The present invention relates to an automatic brake device for a vehicle for preventing collision with other vehicles and obstacles when driving a vehicle.
일반적인 브레이크장치를 설명하기 위한 제1도를 참조하면, 자동차를 정지시키고자 운전자가 브레이크페달(11)을 밟게 되면 푸쉬로드(12)가 이동함에 따라 마스터실린더(14)의 피스톤(13)이 전진하여 유압을 발생시키고, 이 유압이 호스(15)를 통하여 브레이크드럼(18)에 설치된 휠실린더(16)로 전달되어 브레이크슈(17)를 브레이크드럼(18)의 내부면에 밀착시켜 마찰력을 발생시킴으로써 자동차는 제동되는 것이다.Referring to FIG. 1 for explaining a general brake device, when the driver presses the brake pedal 11 to stop the vehicle, the piston 13 of the master cylinder 14 moves forward as the push rod 12 moves. To generate the hydraulic pressure, and the hydraulic pressure is transmitted to the wheel cylinder 16 installed in the brake drum 18 through the hose 15 to bring the brake shoe 17 into close contact with the inner surface of the brake drum 18 to generate frictional force. By doing so, the car is braked.
이와 같은 종래 자동차의 브레이크장치는 운전자의 임의조작에 의해서만 제동되므로 운전자의 조작실수가 발생하였을 경우에는 사고로 직결되는 것이다.Such a conventional brake device of a vehicle is braked only by a driver's arbitrary operation, and thus, when a driver's operation mistake occurs, the brake device is directly connected to an accident.
특히, 복잡한 도심지 주행이나 주정차시에 브레이크 조작의 실수로 인한 접촉사고가 많이 발생하고 있다.In particular, a lot of contact accidents occur due to a mistake in brake operation during complex urban driving or parking.
이와 같은 접촉사고의 발생 이외에도 졸음운전으로 인하여 장애물 근접시에도 브레이크를 밟지 않게 된다면 매우 위험한 사고를 발생되어 인명을 해치게 된다.In addition to the occurrence of such a contact accident, if you do not step on the brakes due to the drowsiness operation due to the drowsy operation is very dangerous accidents occur to harm the lives.
본 발명은 전술한 바와 같은 문제점을 해결하기 위하여 제안된 것으로, 주행속도에 따라 타차량이나 장애물에 근접하면 운전자의 조작에 의하지 않더라도 자동으로 제동되도록 하여 사고를 미연에 방지할 수 있도록 하려는 목적이 있다.The present invention has been proposed to solve the above-mentioned problems, and has an object to prevent accidents by automatically braking when approaching other vehicles or obstacles according to the driving speed, even if not by the driver's operation. .
이와 같은 목적을 달성하기 위한 본 발명에 따르면 전방차량 및 전방장애물과의 거리를 초음파를 이용하여 감지하는 거리감지부와, 상기 거리감지부에서 감지된 신호와 차속센서에서 감지된 신호에 대응하는 평가기준값을 비교처리하기 위한 신호처리부와, 상기 신호처리부의 출력신호에 따라 마스터실린더의 유압을 제어하는 제동부로 구성된 것을 특징으로 하는 자동차의 자동 브레이크장치가 제공된다.According to the present invention for achieving the above object, the distance detection unit for detecting the distance between the front vehicle and the front obstacle using ultrasonic waves, and the evaluation reference value corresponding to the signal detected by the distance detection unit and the signal detected by the vehicle speed sensor An automatic brake apparatus for a vehicle is provided, comprising a signal processor for comparing and a braking unit for controlling hydraulic pressure of a master cylinder according to an output signal of the signal processor.
이하, 도면을 참조하여 본 발명의 바람직한 실시예를 더욱 구체적으로 설명하며, 종래의 기술과 동일한 부분은 같은 부호를 명기하여 표시하였다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings, and the same parts as in the prior art are denoted by the same reference numerals.
제2도는 본 발명에 의한 구성도이고, 제3도는 제동부의 실시예를 도시한 개략적 단면도이다.2 is a configuration diagram according to the present invention, Figure 3 is a schematic cross-sectional view showing an embodiment of the braking unit.
제2도에 도시한 바와 같이, 거리감지부(20)의 출력측과 차속센서(VS)의 출력측이 신호처리부(30)의 입력측에 연결되고 이 신호처리부(30)의 출력측이 제동부(40)의 입력측으로 연결구성된다.As shown in FIG. 2, the output side of the distance sensing unit 20 and the output side of the vehicle speed sensor VS are connected to the input side of the signal processing unit 30, and the output side of the signal processing unit 30 is connected to the braking unit 40. It is connected to the input side.
상기 거리감지부(20)는 초음파센서(21) 및 거리판별회로(22)를 사용하여 거리를 감지하는 통상의 것과 같은 것으로서, 초음파를 송신한 시간과 초음파가 장애물에 반사되어 되돌아와 수신된 시간과의 차이를 이용하여 전방차량 또는 장애물과의 거리를 감지되며, 초음파센서(21)는 차량전방의 범퍼 또는 후론트패널부위에 설치하는 것이 바람직하다.The distance detecting unit 20 is the same as the conventional one for detecting the distance by using the ultrasonic sensor 21 and the distance discrimination circuit 22, and the time when the ultrasonic wave is transmitted and the ultrasonic wave is reflected back to the obstacle and received and The distance between the front vehicle or the obstacle is sensed using the difference between the two, and the ultrasonic sensor 21 is preferably installed at the bumper or the front panel of the front of the vehicle.
또, 상기 신호처리부(30)는 다음 표 1에서와 같은 논리레벨로 신호를 처리하도록 구성된다.In addition, the signal processor 30 is configured to process signals at the logic level as shown in Table 1 below.
이때, 평가기준값은 차속에 비례하는 적정차간 안전거리에 대한 값으로 설정하여 상기 신호처리부(30)에 프로그래밍시킨다.At this time, the evaluation reference value is set to a value for a proper safety distance between vehicles proportional to the vehicle speed and programmed in the signal processor 30.
또한, 상기 제동부(40)는 제3도에 보인 바와 같이 브레이크 페달(11)의 푸쉬로드(12)에 마그네틱 솔레노이드(41)를 결합시키며, 이 마그네틱 솔레노이드(41)는 차체에 결합된 코어부(41a)와, 푸쉬로드(12)에 결합된 코어부(41b)의 이중구조로 이루어져, 이 두 코어부(41a)(41b)에 전류가 인가되면 서로 척력이 작용하여 푸쉬로드(12)에 결합된 코어부(41b) 를 마스터실린더(14)의 피스톤(13)이 전진되는 직선방향으로 슬라이딩 이동시켰다가 전류가 차단되면 유압에 의해 복귀되도록 구성된다.In addition, the braking unit 40 couples the magnetic solenoid 41 to the push rod 12 of the brake pedal 11, as shown in FIG. 3, and the magnetic solenoid 41 has a core coupled to the vehicle body. (41a) and a dual structure of the core portion 41b coupled to the push rod 12. When a current is applied to the two core portions 41a and 41b, a repulsive force is applied to each other to push rod 12. The combined core portion 41b is slidably moved in a linear direction in which the piston 13 of the master cylinder 14 is advanced, and is configured to return by hydraulic pressure when the current is interrupted.
이와 같이 구성된 본 발명은 자동차의 주행중 전방차량 및 전방장애물과 근접하게 되면, 거리감지부(20)는 차량전면에 설치된 초음파센서(21)를 통해 전방차량 및 전방장애물과의 이격거리를 감지하여 거리감지값에 대한 출력신호와, 차속센서(VS)에서 출력되는 주행속도에 대한 차속신호를 신호처리부(30)로 입력하게 된다.When the present invention configured as described above approaches the front vehicle and the front obstacle while driving the vehicle, the distance detecting unit 20 detects the distance between the front vehicle and the front obstacle through the ultrasonic sensor 21 installed on the front of the vehicle and detects the distance. The output signal for the value and the vehicle speed signal for the traveling speed output from the vehicle speed sensor VS are input to the signal processor 30.
이와같이 두가지 신호가 입력된 상기 신호처리부(30)는 저장되어 있는 속도에 비례하여 대응하는 평가기준값에 입력된 거리감지값을 비교하여, 거리감지값이 같거나 작으면 제동부(40)의 솔레노이드(41)를 작동시켜 푸쉬로드(12)를 밀게 되고, 이에 따라 마스터실린더(14)의 피스톤(13)이 전진하여 유압을 발생시키고, 이 유압이 호스(15)를 통하여 브레이크드럼(18)에 설치된 휠실린더(16)로 전달되어 브레이크슈(17)를 브레이크드럼(18)의 내부면에 밀착시켜 마찰력을 발생시키게 되므로 자동차는 즉시 제동상태가 된다.As such, the signal processor 30 inputting two signals compares the distance detection value input to the corresponding evaluation reference value in proportion to the stored speed, and if the distance detection value is the same or smaller, the solenoid of the brake unit 40 ( 41 is operated to push the push rod 12, whereby the piston 13 of the master cylinder 14 is advanced to generate hydraulic pressure, which is installed on the brake drum 18 through the hose 15 Since the vehicle is delivered to the wheel cylinder 16 to bring the brake shoe 17 into close contact with the inner surface of the brake drum 18 to generate a friction force, the vehicle is immediately braked.
이와 같이 제동된 자동차가 전방차량 또는 장애물과 일정거리 이상으로 멀어지게 되면, 전술한 바와는 역논리의 작동으로 제동부(40)의 솔레노이드(41)는 작동을 정지하여 자동차는 다시 진행하던 속도로 주행하게 된다.When the braked vehicle moves away from the front vehicle or the obstacle by a predetermined distance or more, as described above, the solenoid 41 of the brake unit 40 is stopped by the operation of the reverse logic, and the vehicle stops at the same speed. You will drive.
이상에서 설명한 바와 같이, 본 발명은 주행속도에 따른 적정한 차간거리를 확보토록 하고 운전자의 브레이크 조작실수로 인한 충돌사고를 방지하는 효과가 있는 것이다.As described above, the present invention has an effect of ensuring an appropriate inter-vehicle distance according to the traveling speed and preventing a collision accident caused by a driver's brake operation mistake.
