Description
본 발명은 브레이크 바이 와이어(brake-by-wire)식 차량 제동장치에 관한 것으로, 구체적으로 스톱 램프 스위치가 삭제되고 페달스토로크센서에 의하여 브레이크 액츄에이터와 스톱 램프가 작동되는 것에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brake-by-wire vehicle braking apparatus, and more particularly, to a stop lamp switch being deleted and to a brake actuator and a stop lamp operated by a pedal stroke sensor.
일반적으로 브레이크 바이 와이어는 "바이 와이어"라는 전기제어에 의하여 많은 부품이 생략되고 조립이 간소화되도록 하려는 일련의 최근 차량 신기술의 한 종류이다. 종래의 유압 브레이크 또는 ABS 브레이크를 대체하여 전자적 시그널을 통하여 브레이크 압력이 제어되는 개념으로, 브레이크 페달부분과 휠 실린더 등의 브레이크 액추에이터가 분리된다.In general, brake-by-wire is one of a series of new vehicle technologies that seek to simplify many assemblies and simplify assembly by electrical control called "by-wire". The brake pressure is controlled through an electronic signal in place of the conventional hydraulic brake or ABS brake, and the brake pedal and the brake actuator such as the wheel cylinder are separated.
브레이크 바이 와이어 제동장치는 오퍼레이션 페달 유닛(operation pedal unit), 브레이크 제어부 및 브레이크 액츄에이터로 이루어진다. 오퍼레이션 페달 유닛은 종래 유압브레이크의 페달 부분과 유사하지만 마스터실린더 및 부스터에 의한 유압에 의한 신호 대신에 페달스트로크센서에 의한 전기적 신호가 발생된다. 브레이크 제어부는 전기제어회로이고 상기 오퍼레이션 페달 유닛의 신호가 입력되고 페달 답력 및 스트로크 등에 의하여 적정 브레이크 압력이 산출되어 작동신호가 출력된다. 그리고, 브레이크 액츄에이터는 휠실린더, 디스크브레이크의 캘리퍼 또는 전기모터 등으로 이루어지며 브레이크 제어부의 작동신호에 따라 차량의 휠을 제동하게 된다.The brake by wire braking device is composed of an operation pedal unit, a brake control unit and a brake actuator. The operation pedal unit is similar to the pedal part of the conventional hydraulic brake, but an electrical signal is generated by the pedal stroke sensor instead of a signal by the hydraulic pressure by the master cylinder and the booster. The brake control unit is an electric control circuit, the signal of the operation pedal unit is input, the appropriate brake pressure is calculated by the pedal effort and stroke, and the operation signal is output. The brake actuator may include a wheel cylinder, a caliper or an electric motor of a disc brake, and brake the wheel of the vehicle according to an operation signal of the brake controller.
이러한 브레이크 바이 와이어 제동장치는 크게 EMB(Electro-mechanical system)와 EHB(Electro-hydraulic brake)가 있으며, EMB는 브레이크 액츄에이터가 전기모터로 이루어져 전기모터에 의하여 브레이크 패드가 디스크에 마찰되어 제동되는 시스템이다. 그리고 EHB는 브레이크 액츄에이터가 종래의 유압브레이크 장치와 동일한 휠브레이크 또는 디스크 브레이크 형태이고 다만 페달부분에서 전기적 신호가 발생되는 제동장치이다.These brake-by-wire braking devices are largely EMB (Electro-mechanical system) and EHB (Electro-hydraulic brake). EMB is a system in which the brake actuator is composed of an electric motor and the brake pad is frictionally braked to the disc by the electric motor. . The EHB is a brake device in which the brake actuator is the same type of wheel brake or disc brake as the conventional hydraulic brake device, but an electric signal is generated at the pedal part.
종래에는 브레이크 바이 와이어 제동장치는 페달 스트로크 센서가 장착되어, 브레이크 제어부를 경유하여 브레이크 액추에이터가 작동되고, 스톱 램프 스위치가 장착되어 차량의 후미에 위치되는 스톱 램프(stop lamp)가 온/오프 되었다. 그러나, 브레이크 페달에 스톱 램프(stop lamp) 스위치와 이를 장착하기 위한 별도의 브라케트, 커넥터, 와이링이 필요한 번거로운 문제점이 있었다.Conventionally, a brake by wire braking device is equipped with a pedal stroke sensor, a brake actuator is operated via a brake control unit, and a stop lamp is mounted on and off of a stop lamp located at the rear of a vehicle. However, there is a problem in that a brake lamp and a stop lamp switch and a separate bracket, a connector, and a wiring for mounting the stop pedal are required.
상기한 문제점 등을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 묘듈화를 통해 보다 조립시간이 단축되고 부품수가 삭감되는 브레이크 바이 와이어식 차량 제동장치를 제공하는 것이다.In order to solve the above problems and the like, it is an object of the present invention to provide a brake-by-wire vehicle braking device that the assembly time is shortened and the number of parts is reduced through the modularization.
또한, 본 발명의 목적은 페달 스트로크 센서에 의하여 브레이크 액츄에이터와 스톱 램프가 작동되어, 스톱 램프 기능이 안정적이고 정확히 용이하게 구현되며 경량화되는 브레이크 바이 와이어식 차량 제동장치를 제공하는 것이다.In addition, it is an object of the present invention to provide a brake-by-wire vehicle braking device in which the brake actuator and the stop lamp are operated by a pedal stroke sensor, so that the stop lamp function is stably and easily implemented.
상기와 같은 본 발명의 목적이 달성되도록, 본 발명은 브레이크 바이 와이어(brake-by-wire) 방식으로 제동되며 오퍼레이션 페달 유닛과 브레이크 액츄에이터를 포함하는 차량 제동장치에 있어서, 상기 오퍼레이션 페달 유닛에 설치되며 페달의 움직임을 감지하는 페달스트로크센서와; 상기 페달스트로크센서의 신호가 입력되며 상기 브레이크 액츄에이터에 작동신호를 출력하는 브레이크 제어부와; 상기 브레이크 제어부에 연결되어 작동되는 스톱 램프를; 포함한다.In order to achieve the object of the present invention as described above, the present invention is braking-by-wire (brake-by-wire) method of the vehicle braking device including an operation pedal unit and a brake actuator, is installed in the operation pedal unit A pedal stroke sensor for detecting movement of the pedal; A brake control unit configured to input a signal of the pedal stroke sensor and output an operation signal to the brake actuator; A stop lamp connected to the brake control unit and operated; Include.
이하, 첨부도면을 참조하여 본 발명의 바람직한 실시예를 구체적으로 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도1에 되시되듯이, 본 발명에 의한 브레이크 바이 와이어식 차량 제동 장치(10)는 크게 오퍼레이션 페달 유닛(20), 브레이크 제어부(30)와 브레이크 액츄에이터(40)로 이루어져, 차량이 제동되고, 페달 스트로크 센서(24)에 의하여 브레이크 액츄에이터(40)와 스톱 램프(50)가 작동된다.As shown in Figure 1, the brake-by-wire vehicle braking device 10 according to the present invention is largely composed of the operation pedal unit 20, the brake control unit 30 and the brake actuator 40, the vehicle is braked, The brake actuator 40 and the stop lamp 50 are activated by the stroke sensor 24.
상기 오퍼레이션 페달 유닛(20)은 종래의 유압브레이크의 페달 부분과 유사하지만 마스터실린더, 부스터 및 유압라인이 삭제되고 페달스트로크센서(24)가 프레임(22)에 장착되어, 페달(21)의 스트로크가 계측된다. 페달 스트로크 센서(24)는 페달(21)의 변위를 검출하는 각종 변위센서가 이용될 수 있으며 페달(21) 주위의 프레임(22)에 장착된다.The operation pedal unit 20 is similar to the pedal portion of a conventional hydraulic brake, but the master cylinder, the booster and the hydraulic line are deleted and the pedal stroke sensor 24 is mounted to the frame 22, so that the stroke of the pedal 21 is reduced. It is measured. The pedal stroke sensor 24 may use various displacement sensors for detecting the displacement of the pedal 21 and is mounted on the frame 22 around the pedal 21.
상기 브레이크 제어부(30)는 전기적인 제어 유닛(ECU)이며 상기 페달스트로크센서(24)의 신호가 입력된다. 경우에 따라서는 휠속도센서 또는 답력을 측정하는 힘센서 등의 신호도 함께 입력된다.The brake control unit 30 is an electrical control unit ECU and a signal of the pedal stroke sensor 24 is input. In some cases, a signal such as a wheel speed sensor or a force sensor for measuring a stepping force is also input.
상기 브레이크 액추에이터(40)는 휠실린더, 디스크브레이크의 캘리퍼 또는 전기모터 등으로 이루어지며 차량의 휠 부근에 장착되고 상기 브레이크 제어부(30)의 작동신호에 따라, 휠을 제동한다.The brake actuator 40 includes a wheel cylinder, a caliper of an electric disc brake or an electric motor, and is mounted near the wheel of the vehicle and brakes the wheel according to an operation signal of the brake controller 30.
그리고, 상기 스톱 램프(50)는 일반적으로 차량의 후미에 장착되고 제동시 마다 점등되는 램프이다. 상기 스톱 램프(50)는 상기 페달 스트로크 센서(24)의 신호에 따라 상기 브레이크 제어부(30)에서 작동신호가 출력되어, 점등된다. In addition, the stop lamp 50 is generally mounted on the rear of the vehicle and is a lamp that is turned on every braking. The stop lamp 50 is turned on by outputting an operation signal from the brake controller 30 according to the signal of the pedal stroke sensor 24.
이와 같이 구성되는 본 발명은 종래의 브레이크 바이 와이식 차량 제동 장치에서 스톱 램프 기능을 구현하기 위한 스톱램프 스위치, 스톱 램프 스위치용 브라케트, 커넥터, 와이어 등이 불필요하게 되어 보다 조립시간이 단축되고 부품수가 삭감되는 작용효과가 있다. 또한, 본 발명의 목적은 페달 스트로크 센서에 의하여 브레이크 액츄에이터와 스톱 램프가 작동되어, 브레이크 액츄에이터와 스톱 램프가 불일치되어 작동되지 않고 스톱 램프 기능이 안정적이고 정확하고 용이하게 구현되며 경량화되는 작용효과가 있다. The present invention configured as described above eliminates the need for a stop lamp switch, a bracket for a stop lamp switch, a connector, a wire, etc. to implement a stop lamp function in a conventional brake-by-type vehicle braking device, thereby further reducing assembly time and parts. There is an effect that the number is reduced. In addition, the object of the present invention is that the brake actuator and the stop lamp is operated by the pedal stroke sensor, the brake actuator and the stop lamp do not operate inconsistently, there is an effect that the stop lamp function is stable, accurate, easily implemented and lightweight .
