Description

자동차의 브레이크 시스템{BRAKE SYSTEM OF VEHICLE}Brake system of car {BRAKE SYSTEM OF VEHICLE}

본 발명은 자동차의 브레이크 시스템에 관한 것으로, 보다 상세하게는 AVH(Automatic Vehicle Hold) 작동 상태에서도 제동등이 점등 하도록 시스템을 변경하는 것에 의해 개정되는 국내 안전법규를 만족시킬 수 있는 차량의 브레이크 시스템에 관한 것이다.The present invention relates to a brake system of a vehicle, and more particularly, to a brake system of a vehicle capable of satisfying the national safety legislation, which is amended by changing the system so that the braking light turns on even in an AVH (Automatic Vehicle Hold) operation state. will be.

현재 국내 안전 기준법규(제43조)에 따르면, "자동차의 주제동장치(brake)를 조작할 때에 점등(brake 点燈)이 되고, 제동장치 조작을 해제 시까지 지속적으로 점등상태를 유지할 것"으로 되어 있다. 즉, 운전자가 인위적으로 차량을 정지시키기 위해 브레이크와 같은 제동장치를 이용하여 제동시, 반드시 차량후미의 브레이크 등은 점등되어야 하며, 제동장치가 해제될 때까지 브레이크 등은 계속 "on"상태를 유지시켜 후행 운전자에게 차량의 운행정보(차량 정차 또는 일시정지)를 공지하여 차량 충돌 등의 안전사고를 사전에 예방하고 있다.According to the current national safety standard regulation (Article 43), "It should be on when operating the main brake of the vehicle, and it will stay on until the brake operation is released." It is. That is, when the driver brakes by using a braking device such as a brake to artificially stop the vehicle, the brake light at the rear of the vehicle must be turned on, and the brake light remains "on" until the brake device is released. By notifying the following driver of driving information (vehicle stopping or stopping) of the vehicle, safety accidents such as a vehicle collision are prevented in advance.

그러나, 국내 안전법규가 최근 개정됨에 따라 현재 특정 차량에 적용되는 AVH(Automatic Vehicle Hold) 시스템 적용이 불가하게 되는 문제가 발생한다.However, as domestic safety regulations have recently been revised, a problem arises in that the automatic vehicle hold (AVH) system that is currently applied to a specific vehicle cannot be applied.

상기 AVH 기능은 주행중 주브레이크 장치를 이용하여 임시 정차 및 주차할 수 있는 기능이다.The AVH function is a function for temporarily stopping and parking by using the main brake device while driving.

현재까지는 이와 관련된 항목으로, 자동차의 주 제동장치(brake)를 조작할 때에 점등(brake 点燈)이 되고, 제동장치 조작을 해제 시까지 지속적으로 점등상태를 유지할 것으로 되어 있었다.Until now, it has been related to this, and when the main brake of the vehicle is operated, the lamp is turned on and the lighting state is continuously maintained until the brake operation is released.

상기 새로운 개정안에 의하면, "주 제동장치 또는 리타더(retarder)에 의해 제동력이 발생될 때 점등되고, 주 제동장치 또는 리타더에 의한 제동력이 해제될 때까지 지속적으로 점등상태를 유지할 것"이다. 참고로, 상기 리타더는 지동자의 속도를 줄이는 장치로서, 브레이크 이외에 주행 에너지를 흡수하여 감속작용을 하는 것이다.
따라서, 종래에는 AVH 작동 중(브레이크 페달을 밟지 않은 상태 ONLY)에서는 제동등이 미점등되는 데 비해, 개정안에서는, AVH 작동상태에서 제동등이 점등하게끔 시스템을 변경할 경우, 시프트-록(Shift-Lock)의 기능 상실로 안전성에 심각한 문제가 발생하게 된다.
According to the new amendment, "lights up when the braking force is generated by the main braking device or the retarder, and will remain on until the braking force by the main braking device or the retarder is released". For reference, the retarder is a device for reducing the speed of the mover, and absorbs driving energy in addition to the brake to decelerate.
Therefore, while the conventional brake light does not turn on during the AVH operation (with the brake pedal ONLY), in the amendment, when the system is changed so that the brake light turns on in the AVH operation state, the shift-lock Loss of function causes serious safety problems.

도 1 은 종래의 주 제동장치의 조작에 따른 점등상태를 도시하는 회로도이다.1 is a circuit diagram showing a lighting state according to the operation of a conventional main braking device.

상기 회로도에서, ECU(10)와 ESP(30) 간에는 CAN(Controller Area Network) 통신이 이루어지는 상태이다.In the circuit diagram, controller area network (CAN) communication is performed between the ECU 10 and the ESP 30.

종래의 주 제동장치의 조작 시스템에 있어서, 운전자가 주행중일 경우에는 브레이크 페달 작동 신호가 발생하지 않으므로 ECU(Engine Control Unit)(10)가 조정하는 두 접점 스위치, 즉 BRLS(Brake Lamp Switch)(33)와 BS(Brake Switch) 중, 어느 하나의 스위치 접점이 온(On) 상태가 되고, 다른 하나는 오프 상태가 된다.
예컨대, 차량의 주행중인 상태에서는, 상기 도면에서 도시된 바와 같이, BRLS 는 스위치가 작동되는 온(On) 상태이고, BS 는 미작동 상태인 오프(Off)가 되는 형태로 작동한다. 이 경우, 브레이크 페달 작동신호가 발생하지 않으므로 ESP(30)와 ECU(10)간 CAN(Controller Area Network) 통신이 이루어지지 않으며, 이에 따라 CAN 상의 전달되는 정보도 없는 상태가 된다.
In the conventional main braking operation system, since the brake pedal operation signal is not generated when the driver is driving, two contact switches that are controlled by the ECU (Engine Control Unit) 10, that is, brake lamp switches (BRLS) 33 ) And BS (Brake Switch), one of the switch contact is turned on (On), the other is off.
For example, in the driving state of the vehicle, as shown in the figure, the BRLS operates in a form in which the switch is turned on, and the BS is turned off, which is inactive. In this case, since the brake pedal operation signal does not occur, communication of the controller area network (CAN) is not performed between the ESP 30 and the ECU 10, and thus there is no information transmitted on the CAN.

운전자가 브레이크 페달(31)을 밟아 제동을 하게 되면(Brake Pedal On), 먼저, ECU(10)와 ESP(30)와의 CAN 통신상에 브레이크 페달 작동신호를 입력하고, 다음으로, ESP(30)와 ECU(10)간 브레이크 페달 작동신호가 와이어로 전달됨으로 인해 ECU(10)의 BRLS 가 온(On) 되며, 연동되어 있는 BRL(13)이 배터와이어링 전원단과 접속되어 전원이 BRL(10)로 전달되어 점등된다.When the driver brakes by stepping on the brake pedal 31 (Brake Pedal On), first, a brake pedal operation signal is input on CAN communication between the ECU 10 and the ESP 30, and then the ESP 30 BRLS of the ECU 10 is turned on because the brake pedal operation signal between the ECU 10 and the ECU 10 is transmitted to the wire, and the BRL 13 interlocked with the batter wiring power terminal is connected to the power supply to the BRL 10. It is delivered and lights up.

신규 법규 개정안에 대한 대응 시(AVH 기능 작동시)에는, 운전자가 정지(idle)에 가까운 속도에서 AVH 를 작동시키면 ESP(30)가 BRL 릴레이(Relay)를 작동시켜 일순 차량이 정지되면서 BRL(33)을 접점 시킨다.In response to the new legislative amendment (when the AVH function is activated), if the driver operates the AVH at a speed close to the idle, the ESP 30 activates the BRL relay to stop the first vehicle and stop the BRL (33). )).

한편, 신법규에 의하면 차량 제동상태가 해제될 때까지 램프가 계속 온(On) 상태로 유지되지 않으면 법규 위반이 되게 된다. 이때 운전자는 브레이크를 해제했음에도 램프가 계속 온 상태가 되면 ECU 는 운전자가 브레이크 페달을 밟은 것으로 인지하여 R단으로의 변속단 변경이 가능하게 되는 상황이 발생하게 된다. 즉, 운전자는 무의식중에 변속단을 터치하여 R단으로 유지된 상태에서 액셀 페달을 밟아 차량이 후진하여 위험한 상황이 발생될 소지가 있게 된다.On the other hand, according to the new law, if the lamp is not kept on until the vehicle braking state is released (On) will be a violation of the law. At this time, when the driver keeps the lamp on even though the driver releases the brake, the ECU recognizes that the driver has pressed the brake pedal and the shift stage to the R stage can be changed. That is, when the driver unconsciously touches the shift stage and presses the accelerator pedal in the state maintained at the R stage, the driver may reverse the vehicle and a dangerous situation may occur.

따라서 본 발명은 상기한 종래의 문제점을 해결하기 위한 것으로, ESP 와 ECU 간의 와이어링(Wiring) 상에 다이오드를 설치함에 의해 ESP 에 의해 브레이크 신호가 ECU 측으로 전달되지 않도록 함으로써, 차량의 제동상태가 해제될 때까지 램프가 계속 온 상태로 유지되고, R단으로 변속변경이 되는 위험이 없도록 하는 차량의 브레이크 시스템을 제공하는 것을 목적으로 한다.Accordingly, the present invention is to solve the above-mentioned conventional problem, by preventing the brake signal from being transmitted to the ECU by the ESP by installing a diode on the wiring between the ESP and the ECU, the braking state of the vehicle is released. It is an object of the present invention to provide a brake system for a vehicle in which the lamp is kept on until the vehicle is kept in a state where there is no risk of shifting to the R stage.

상기 목적을 달성하기 위한 본 발명의 차량의 브레이크 시스템은 ESP와 ECU의 사이에 설치된 와이어링 상에 다이오드를 설치하여, AVH 작동 상태에서 BRL이 작동되더라도 ESP에 의해 브레이크 페달 작동 신호가 상기 다이오드에 의해 차단되어 ECU로 전달되지 않도록 하여, R 단으로의 기어변속이 방지되고, 주 제동장치 또는 리타더에 의한 제동력이 해제될 때까지 점등상태가 유지되게 한 것을 특징으로 한다.The brake system of the vehicle of the present invention for achieving the above object is to install a diode on the wiring installed between the ESP and the ECU, so that even if the BRL is operated in the AVH operating state, the brake pedal operation signal is driven by the diode by the ESP. It is characterized in that the gear is prevented from being cut off and transmitted to the ECU, so that the gear shift to the R stage is prevented and the lighting state is maintained until the braking force by the main braking device or the retarder is released.

본 발명의 차량의 브레이크 시스템에 의하면, ESP와 ECU의 사이의 와이어링 상에 다이오드를 설치함에 의해 AVH 작동 상태에서 제동 등이 작동되더라도 R 단으로의 기어변속이 이루어지는 것에 따른 위험 상황이 발생되지 않으며, 주 제동장치 또는 리타더에 의한 제동력이 해제될 때까지 지속적으로 점등상태가 유지되게 하는 효과를 발휘한다.According to the brake system of the vehicle of the present invention, even if the braking or the like is operated in the AVH operating state by installing a diode on the wiring between the ESP and the ECU, a dangerous situation due to the gear shift to the R stage is not generated. In this case, the lighting state is continuously maintained until the braking force by the main braking device or the retarder is released.

이하 첨부된 도면을 참조하여 본 발명의 차량의 브레이크 시스템의 적합한 실시예에 대해 상세히 설명하기로 한다.Hereinafter, a preferred embodiment of a brake system of a vehicle of the present invention will be described in detail with reference to the accompanying drawings.

도 2 는 본 발명에 따른 주 제동장치의 조작에 따른 점등상태를 도시하는 회로도이다.2 is a circuit diagram showing a lighting state according to the operation of the main braking device according to the present invention.

상기 회로도에서, ECU(10)와 ESP(50) 간에는 CAN(Controller Area Network) 통신이 이루어지는 상태이다.In the circuit diagram, controller area network (CAN) communication is performed between the ECU 10 and the ESP 50.

도시된 바와 같이, 신규한 법규에 대응한 본 발명의 차량의 브레이크 시스템에서는 ESP(50)와 ECU(10)의 사이에 설치된 와이어링(Wiring)상에 다이오드(60)를 설치한 구성으로 이루어진다.As shown, the brake system of the vehicle of the present invention corresponding to the new law has a configuration in which a diode 60 is provided on a wiring provided between the ESP 50 and the ECU 10.

따라서, 상기 다이오드(60)가 설치된 상태 하에서 AVH 를 작동하게 되면, ESP(50)는 차속이 인지되기 전까지 BRL(53) 이 작동되지만, 상기 다이오드(60)에 의해 ESP(50)에서의 브레이크 페달작동 신호가 ECU(10)로 전달되지 않게 된다. 즉, ESP(50)의 브레이크 페달작동 신호가 ECU(10)로 전달되지 않음으로 R 단으로의 기어변속이 이루어지는 위험은 없어지게 된다.Accordingly, when the AVH is operated under the state in which the diode 60 is installed, the BSP 53 is operated until the vehicle speed is recognized by the ESP 50, but the brake pedal at the ESP 50 is driven by the diode 60. The operation signal is not transmitted to the ECU 10. That is, since the brake pedal operation signal of the ESP 50 is not transmitted to the ECU 10, the risk of gear shifting to the R stage is eliminated.
