Description

차량의 자동 브레이크 제어방법Auto brake control method of vehicle

본 발명은 차량의 자동 브레이크 제어방법에 관한 것으로, 더욱 상세하게는 위험지역에 설치된 제한속도 신호발생기에서 보내는 제한속도신호를 받거나 인공위성에서 보내온 통신정보로 현재의 자동차가 과속을 하고 있으면 엔진브레이크와 ABS를 자동으로 작동되게 하여 차속을 줄이도록 하고, ABS가 미작동되는 에러가 발생시 경고음이나 경고등이 작동되는 한편 상기 에러사항이 디스플레이부에서 표시될수 있도록 하는 차량의 자동 브레이크 제어방법에 관한 것이다.The present invention relates to an automatic brake control method for a vehicle. More specifically, the engine brake and ABS are received when the current vehicle is overspeed by receiving a speed limit signal from a speed limit signal generator installed in a hazardous area or communication information sent from a satellite. The automatic brake control method of the vehicle to reduce the vehicle speed by the automatic operation, and when the error occurs when the ABS non-operation, the beep or warning light is operated while the error information can be displayed on the display.

유압식 브레이크가 장착된 고급차량에는 브레이크 안전성능향상 장치인 ABS(Anti-locking Brake System)가 설치되어 있는데, 이 장치는 초당 10여회 이상의 더블 브레이크를 밟는 것과 같은 효과를 낸다.High-end vehicles equipped with hydraulic brakes are equipped with an anti-locking brake system (ABS), which improves brake safety performance, which is equivalent to pressing a double brake more than 10 times per second.

ABS장착 차량은 급제동시 브레이크 마스터 실린더로부터 유압을 수회의 펌핑유압으로 바꿔 순차적으로 전달함으로써 더블 브레이크 효과를 주게 되어 브레이크를 밟고 있는 동안에도 핸들조작기능 및 제동거리감소, 선회방지가 가능하게 되는 것이다.ABS-equipped vehicles convert the hydraulic pressure from the brake master cylinder to several pumping hydraulic pressures in order to deliver a double brake effect. This makes it possible to operate the steering wheel, reduce the braking distance and prevent turning while the brakes are being applied.

또한, 항공기와 선박에 사용되는 내비게이션 시스템(Navigation System)이 구비된 차량도 일반화되는 추세인데, 이는 인공위성이나 차량 외부의 전파 발신원 등으로부터 보내온 정보를 이용하여 차 실내의 디스플레이부에 지도와 함께 현재 위치, 진행방향, 목적지까지의 거리 등이 표시되는 시스템이다.In addition, vehicles equipped with navigation systems used in aircraft and ships are also becoming more common, which is based on the current position along with a map on the display unit inside the car using information sent from satellites or radio wave sources outside the vehicle. , The direction of travel and the distance to the destination are displayed.

그러나, 종래의 ABS나 내비게이션 시스템이 설치된 차량이라도 운전자가 직접 도로의 여건을 판단하여 차량의 브레이크를 제어해주도록 되어있어서 커브길 또는 공사중인 도로 등 위험지역을 주행시에 운전자가 그 도로에 익숙한 상태가 아니면 자칫 브레이크 조작시기를 놓치게 되어 위험에 직면하게 되는 등의 문제가 있었다.However, even in a vehicle equipped with a conventional ABS or navigation system, the driver directly determines the road conditions and controls the brake of the vehicle, so that the driver is familiar with the road when driving in a dangerous area such as a curve road or a road under construction. Or there is a problem such as missing the brake operation time to face the danger.

따라서, 본 발명은 상기한 종래의 문제를 해결하기 위하여 안출된 것으로, 위험지역에 설치된 제한속도 신호 발생기에서 보내는 제한속도신호를 받거나 인공위성에서 보내온 통신정보로 현재의 자동차가 과속을 하고 있으면 엔진브레이크와 ABS를 자동으로 작동되게 하여 차속을 줄이도록 하고, ABS가 미작동되는 에러가 발생시 경고음이나 경고등이 작동되는 한편 상기 에러사항이 디스플레이부에서 표시될수 있도록 한 차량의 자동 브레이크 제어방법을 제공하고자 함에 발명의 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and if the current vehicle is overspeed with the communication information sent from the satellite or the speed limit signal sent from the speed limit signal generator installed in the hazardous area, the engine brake and The present invention is to provide an automatic brake control method of a vehicle in which the ABS is automatically operated to reduce the vehicle speed, and an alarm sound or a warning light is activated when an error in which the ABS is inoperative occurs and the error information can be displayed on the display unit. There is a purpose.
