본 발명은 전자제어식 브레이크 시스템용 전자제어장치에 관한 것으로, 더욱 상세하게는 ECU 하우징에 설치되어 솔레노이드밸브 및 모터 등의 전기부품과 전기적으로 접속되는 회로기판을 갖춘 전자제어식 브레이크 시스템용 전자제어장치에 관한 것이다.The present invention relates to an electronic control apparatus for an electronically controlled brake system, and more particularly, to an electronic control apparatus for an electronically controlled brake system having a circuit board installed in the ECU housing and electrically connected to electrical parts such as a solenoid valve and a motor. It is about.

일반적으로 전자제어식 브레이크 시스템은 차량의 슬립현상을 효율적으로 방지하여 강력하고 안정된 제동력을 얻기 위한 것으로, 제동 시 휠의 미끄러짐을 방지하는 안티록 브레이크 시스템(ABS:Anti-Lock Brake System)과, 차량의 급발진 또는 급가속시 구동륜의 슬립을 방지하는 브레이크 트랙션 제어 시스템(BTCS:Brake Traction Control System)과, 안티록 브레이크 시스템과 트랙션 제어를 조합하여 브레이크 액압을 제어함으로써 차량의 주행상태를 안정적으로 유지시키는 차량자세제어 시스템(VDC:Vehicle Dynamic Control System) 등이 개시되어 있다.In general, the electronically controlled brake system effectively prevents the slip of the vehicle and obtains a strong and stable braking force.Anti-lock brake system (ABS) to prevent the wheel from slipping during braking and Brake Traction Control System (BTCS) which prevents slippage of driving wheel during sudden start or acceleration, and anti-lock brake system and traction control are combined to control brake hydraulic pressure to keep the vehicle stable. A posture control system (VDC) and the like are disclosed.

이러한 전자제어식 브레이크 시스템은 차량의 휠브레이크 측으로 전달되는 제동유압을 제어하기 위한 다수개의 솔레노이드밸브와, 오일을 일시 저장하는 저압어큐뮬레이터와, 저압어큐뮬레이터에 일시 저장된 오일을 강제 펌핑하기 위한 펌프 및 모터와, 펌프에서 펌핑되는 오일의 압력맥동을 저감시키기 위한 고압어큐뮬레이터와, 솔레노이드밸브 및 펌프 구동을 전기적으로 제어하기 위한 전자제어장치(ECU;Electronic Control Unit)를 포함하고 있다.The electronically controlled brake system includes a plurality of solenoid valves for controlling braking hydraulic pressure delivered to the wheel brake side of a vehicle, a low pressure accumulator for temporarily storing oil, a pump and a motor for forcibly pumping oil temporarily stored in the low pressure accumulator, It includes a high pressure accumulator for reducing the pressure pulsation of the oil pumped from the pump, and an electronic control unit (ECU) for electrically controlling the solenoid valve and the pump operation.

이러한 솔레노이드밸브의 밸브조립체와 어큐뮬레이터 및 펌프, 모터 등은 알 루미늄재의 유압블럭에 콤팩트하게 설치되며, 전자제어장치는 솔레노이드밸브의 코일조립체와 회로기판이 내장된 ECU 하우징을 구비하여 유압블럭과 볼트결합되는데, 이의 상세한 구조는 다음과 같다.The valve assembly of the solenoid valve, the accumulator, the pump, the motor, etc. are compactly installed in the hydraulic block made of aluminum, and the electronic controller has an ECU housing in which the solenoid valve coil assembly and the circuit board are integrated. Its detailed structure is as follows.

도 1을 참조하면, 종래 전자제어식 브레이크 시스템의 유압블럭(1)에는 솔레노이드밸브(2)의 밸브조립체(2a)가 콤팩트하게 압입 설치되어 있다.Referring to FIG. 1, a valve assembly 2a of a solenoid valve 2 is press-fitted in a hydraulic block 1 of a conventional electronically controlled brake system.

그리고 전자제어장치(3)는 유압블럭(1)과 볼트(5) 결합되는 ECU 하우징(3a)과, 이 ECU 하우징(3a)의 상측공간에 장착되는 회로기판(4)를 구비한다. 이 ECU 하우징(3a)의 하측공간 내부에는 솔레노이드밸브(2)의 코일조립체(2c)가 다수개 장착된다.The electronic controller 3 includes an ECU housing 3a coupled to the hydraulic block 1 and a bolt 5 and a circuit board 4 mounted in an upper space of the ECU housing 3a. A plurality of coil assemblies 2c of the solenoid valve 2 are mounted in the lower space of the ECU housing 3a.

코일조립체(2c)는 원통형상으로 코일(2d)이 권선된 보빈(2e)과, 이 코일(2d)의 외측을 감싸는 통상의 케이스(2f)를 갖추고 있다. 따라서 ECU 하우징(3a)과 유압블럭(1)을 결합하는 경우에 보빈(2e)의 중심부에 밸브조립체(2a)의 슬리브(2b)가 여유 있게 삽입된다.The coil assembly 2c is provided with the bobbin 2e by which the coil 2d was wound in cylindrical shape, and the normal case 2f which wraps the outer side of this coil 2d. Therefore, when the ECU housing 3a and the hydraulic block 1 are coupled, the sleeve 2b of the valve assembly 2a is inserted in the center of the bobbin 2e with a margin.

또한, ECU 하우징(3a)은 사각의 벽체를 갖도록 플라스틱재로 사출 성형되는데, 이의 바닥면(3b)에는 코일조립체(2c) 등에서 연장된 핀(Pin) 타입의 리드선(3c)이 회로기판(4)을 향해 돌출되어 있다. 따라서 리드선(3c)과 회로기판(4)을 용접수단을 통해 접합하면 이들이 전기적으로 접속됨으로써, 회로기판(4)을 통해 솔레노이드밸브(2)의 개폐 작동을 제어하게 된다.

즉, ECU 하우징(3a)의 바닥면에 돌출되게 마련된 핀(Pin) 타입의 리드선(3c)을 회로기판(4)에 삽입한 후 땜납을 통해 솔더링(Soldering)함으로써, 단자(3)와 회로기판(4)이 도통된다. That is, the terminal 3 and the circuit board are formed by inserting a pin-type lead wire 3c protruding from the bottom of the ECU housing 3a into the circuit board 4 and soldering it through solder. (4) is conducted.

In this way, the lead wire 3c protruding from the ECU housing 3a and the circuit board 4 must be welded one by one, thereby making it difficult to assemble the circuit board 4 and increasing the working time to increase the manufacturing cost. There are several problems.

한편, 커넥터(41)의 탄성편(41b)과 접촉하는 단자(42)가 회로기판(33)의 일측 가장자리에 일렬로 배치되어 있기 때문에, 회로기판(33)에서 반도체 디바이스(33a)와 같은 부품의 집약도를 높일 수 있다.On the other hand, since the terminals 42 in contact with the elastic pieces 41b of the connector 41 are arranged in one line at one edge of the circuit board 33, the components such as the semiconductor device 33a in the circuit board 33 are arranged. Can increase the intensity.

또한, 본 발명의 실시 예에서는 솔레노이드밸브(20)와 회로기판(33)을 접속시키는 수단을 예로 하여 설명하였지만, 이에 국한하지 않고 유압블럭(10)에 장착되어 펌프를 구동시키는 모터(미도시)의 전원입력단과 회로기판(33)을 접속시키는 것에도 본 발명의 기술적 사상을 적용할 수 있음은 물론이다. In addition, although the embodiment of the present invention has been described using the means for connecting the solenoid valve 20 and the circuit board 33 as an example, a motor (not shown) mounted on the hydraulic block 10 to drive the pump is not limited thereto. It is a matter of course that the technical idea of the present invention can be applied to the connection between the power input terminal and the circuit board 33.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 전자제어식 브레이크 시스템용 전자제어장치에 의하면, 일단이 솔레노이드밸브 등의 전기부품과 접속되도록 ECU 하우징의 바닥면에 배치되며 타단은 ECU 하우징의 바닥면으로부터 돌출되게 마련된 복수개의 커넥터와, 이 커넥터의 타단과 대응하도록 회로기판에 형성된 복수개의 단자를 갖추고 있어서, 체결부재를 통해 회로기판을 고정하는 과정에서 커넥터의 타단과 단자가 직접 접속된다. 이에 따라 별도의 솔더링 작업이 필요 없이 회로기판을 조립함과 동시에 전기부품이 도통됨으로써, 회로기판의 조립 작업성이 보다 향상되며 이의 제조비용 역시 절감되는 작용효과가 있다. As described in detail above, according to the electronic control apparatus for an electronically controlled brake system according to the present invention, one end is disposed on the bottom surface of the ECU housing so as to be connected to an electrical component such as a solenoid valve, and the other end protrudes from the bottom surface of the ECU housing. And a plurality of connectors provided on the circuit board so as to correspond to the other ends of the connectors, and the other end of the connector and the terminal are directly connected in the process of fixing the circuit board through the fastening member. Accordingly, the electrical components are connected at the same time as the assembly of the circuit board without the need for a separate soldering operation, the workability of the assembly of the circuit board is further improved and its manufacturing cost is also reduced.
