Description

자동차용 에이비에스 센서{a sensor of antilock brake system for cars}ABS sensor for car {a sensor of antilock brake system for cars}

본 발명은 자동차용 에이비에스 센서에 관한 것으로서, 더욱 상세하게는 홀(Hall) 효과와 자기저항 효과를 이용하여, 분해능이 높고 제로 스피드(Zero speed) 검지가 가능하게 구성된 자동차용 에이비에스 센서에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automotive ABS sensor, and more particularly, to an automotive ABS sensor configured to have high resolution and zero speed detection using a Hall effect and a magnetoresistance effect. will be.

통상적으로 자동차용 에이비에스(Antilock brake system)는 차속에 비례하는 기본 제동거리 및 전후륜 고착으로 마찰계수가 저하되어 조향력 상실 및 차체 스핀등의 불가항력으로 발생되는 피해를 최소화시키고자 개발된 것으로서, 각 바퀴에 분배되는 제동유압을 제어하여 미끄럼율을 감소시킴에 따라, 제동시 차체의 안정성을 확보할 수 있고, 운전자 의지에 따라 조향 능력 유지를 도모할 수 있으며, 제동거리 단축으로 인하여 인적 물적 피해를 최소화시킬 수 있는 장점을 제공하게 된다.Generally, anti-lock brake system for automobiles was developed to minimize damage caused by force majeure such as loss of steering power and body spin due to reduced friction coefficient due to basic braking distance and front wheel fastening proportional to vehicle speed. By reducing the sliding rate by controlling the brake hydraulic pressure distributed to the wheels, it is possible to secure the stability of the vehicle body during braking, to maintain steering ability according to the driver's will, and to prevent human physical damage by reducing the braking distance. It provides an advantage that can be minimized.

종래의 에이비에스의 구성과 작용을 첨부한 도 4를 참조로 간략히 설명하면 다음과 같다.If briefly described with reference to Figure 4 attached to the configuration and operation of the conventional ABS as follows.

앞바퀴의 허브 축등에 설치된 톤 휠(40)(Tone wheel)의 회전속도를 스피드 감지 센서(26)에서 감지하여, ECU에 그 신호를 전달하게 된다.The speed sensor 26 detects the rotational speed of the tone wheel 40 installed on the hub shaft of the front wheel, and transmits the signal to the ECU.

이때, 상기 스피드 감지 센서(26)의 내부에 영구자석이 설치되어 있는 바, 영구자석의 폴피스 부분이 톤 휠의 회전속도를 감지하게 된다.At this time, the permanent magnet is installed inside the speed sensor 26, the pole piece portion of the permanent magnet to detect the rotational speed of the tone wheel.

즉, 첨부한 도 5에 도시한 바와 같이, 회전하는 톤 휠(40)에 센서(26)를 근접시키면 센서와 톤 휠 사이의 거리가 변하고, 이 거리의 변화에 따라 코일을 통과하는 자속량의 변화가 코일의 유도전압을 발생시키게 되며, 이 전압신호가 ECU에전달되어진다.That is, as shown in FIG. 5, when the sensor 26 is brought close to the rotating tone wheel 40, the distance between the sensor and the tone wheel changes, and the amount of magnetic flux passing through the coil is changed according to the change of this distance. The change causes the induced voltage of the coil, which is then sent to the ECU.

다음으로, 상기 ECU에서는 하이드로릭 유니트(hydraulic unit)에 신호를 보내게 되고, 하이드로릭 유니트(hydraulic unit)는 각각의 휠 실린더의 유압을 조절하게 되어 브레이킹이 이루어진다.Next, the ECU sends a signal to a hydraulic unit, and the hydraulic unit adjusts the hydraulic pressure of each wheel cylinder to perform braking.

상기 종래의 에이비에스 센서는 마그네틱을 포함하는 외장형 센서가 톤 휠에 근접되게 위치시킨 구조로 되어 있으나, 외부로 노출되어 있어서 외부환경(오염먼지, 물)에 의하여 효율이 떨어지게 되고, 가변저항에 의하여 속도를 감지하여 분해능이 낮고, 제로 스피드의 검출이 불가능한 단점이 있었다.The conventional ABS sensor has a structure in which an external sensor including a magnetic is placed in close proximity to a tone wheel, but is exposed to the outside, thereby reducing efficiency due to an external environment (dust, water), and by a variable resistor. Detecting the speed was low resolution, there was a disadvantage that can not detect the zero speed.

또한, 종래의 에이비에스 센서의 출력은 정현파이기 때문에 변환회로가 필요하고, 회전속도에 따른 출력변화가 심하여 신호처리가 어려웠고, 센서 신호에 외부 노이즈가 혼입되어 별도의 IC칩이 필요한 단점이 있었다.In addition, since the output of the conventional ABS sensor is a sine pie, a conversion circuit is required, and the signal processing is difficult due to the severe change in output according to the rotational speed, and external noise is mixed in the sensor signal, which requires a separate IC chip.

따라서, 본 발명은 상기와 같은 점을 감안하여 안출한 것으로서, 제로 스피드를 검출하고, 신호처리 회로가 필요 없으며, 또한 출력형태가 사인파가 아닌 구형파이기 때문에 별도의 변환회로가 필요없으며, 회전속도에 따른 출력변화가 작아 ECU와의 신호처리가 용이하게 이루어지게 하여, 그 성능을 향상시킨 내장형의 자동차용 에이비에스 센서를 제공하는데 그 목적이 있다.Therefore, the present invention has been devised in view of the above-mentioned point, and it detects zero speed, does not need a signal processing circuit, and does not need a separate conversion circuit because the output form is a square pie instead of a sine wave. It is an object of the present invention to provide a built-in automotive ABS sensor which has a small output change and thus facilitates signal processing with an ECU, thereby improving its performance.

상기 마그네트 링(14)의 외주면에는 마그네트(12)가 장착되는 바, 상기 마그네트(12)는 링형으로 성형되되, 그 내부에 요철결합으로 인서트 몰드와 부시가 요철결합 되어 있다.The magnet 12 is mounted on the outer circumferential surface of the magnet ring 14, the magnet 12 is formed in a ring shape, the insert mold and the bush is concave-convex by the concave-convex coupling therein.

한편, 상기 마그네트(12)는 자극은 N극과 S극 영역이 반복되며 균등 분할되어 형성되고, 그 자극수는 차량의 에이비에스시스템에 따라 달리하여 형성시킬 수 있다.On the other hand, the magnet 12 is the magnetic pole is formed by the N pole and the S pole region is repeated and evenly divided, the number of poles can be formed differently depending on the ABS system of the vehicle.

따라서, 상기 차륜축의 베어링의 샤프트(22)에 상기 마그네트 링(14)이 삽입 장착되어진다.Therefore, the magnet ring 14 is inserted into the shaft 22 of the bearing of the wheel shaft.

좀 더 상세하게는 상기 케이스(30)의 내후면에는 센서(26)가 에폭시수지(36)에 의하여 접합되며 장착되는 바, 이 센서(26)는 상기 마그네트(12)와 인접되게 위치되도록 장착된다.More specifically, the sensor 26 is attached to the inner and rear surfaces of the case 30 by the epoxy resin 36, and the sensor 26 is mounted to be positioned adjacent to the magnet 12. .

또한, 상기 케이스(30)의 내후면에는 센서(26)의 신호출력단 역할을 하는 것으로서, 몰딩체(34)의 내부에 함몰되어 있는 부분에 센서를 장착하여 에폭스 수지로 고정 후 상기 터미널(28)을 포함하는 몰딩체(34)에 오버 몰딩하는 구조로 되어 있다.In addition, the inner and rear surfaces of the case 30 serve as a signal output terminal of the sensor 26. The sensor is mounted on a portion recessed inside the molding 34 and fixed with an epoxy resin. The overmolding is carried out to the molding 34 containing ().

상기 터미널(28)의 끝단은 케이스(30)의 후면에 형성된 커넥터 장착구(32)까지 연장시켜, ECU와 연결되는 커넥터와 연결되도록 한다.The end of the terminal 28 extends to the connector mounting hole 32 formed in the rear of the case 30, so that it is connected to the connector connected to the ECU.

여기서 상기와 같은 구성으로 이루어진 본 발명의 자동차용 에이비에스 센서의 작동상태를 설명하면 다음과 같다.Referring to the operation state of the automotive ABS sensor of the present invention made of the above configuration as follows.

차륜축의 회전과 동시에 상기 베어링의 샤프트(22)가 회전을 하게 되면, 상기 마그네트 링(14)과 마그네트(12)도 함께 회전을 하게 되는 바, 이때 마그네트(12)의 자장 변화는 인접되게 설치된 센서(26)에 회전속도 신호로서 출력되어진다.When the shaft 22 of the bearing rotates at the same time as the wheel shaft rotates, the magnet ring 14 and the magnet 12 also rotate together, wherein the magnetic field change of the magnet 12 is adjacently installed. It is output to the rotation speed signal at (26).

좀 더 상세하게는, 본 발명의 에이비에스 센서는 첨부한 도 2에 도시한 바와 같이, 자기저항소자에 자석의 자력선을 가하면 자력선의 세기에 따라 저항이 변하는 자기저항 소자의 특성을 이용하거나, 첨부한 도 3에 도시한 바와 같이 입력단자(a-b)간에 IH되는 홀(hall) 전류를 흘리면 출력단자(c-d)에는 VH되는 홀전압이 출력되며, 이 출력은 자속의 세기에 의존하는 특성을 이용한 것으로서, 상기 마그네트(12)의 회전으로 인한 자장의 변화를 상기 센서(26)에서 감지하여 터미널(28)로 출력하게 되고, 이 출력신호는 터미널(28)에 끼워지는 커넥터에 의하여 ECU에 전달되어진다.More specifically, the ABS sensor of the present invention uses the characteristics of the magnetoresistive element whose resistance changes according to the strength of the magnetic force line when the magnetic force line of the magnet is applied to the magnetoresistive element, as shown in FIG. As shown in FIG. 3, when a hall current that is IH flows between the input terminals ab, the output voltage cd outputs a hall voltage that is VH, and the output uses characteristics that depend on the strength of the magnetic flux. The sensor 26 detects a change in the magnetic field due to the rotation of the magnet 12 and outputs it to the terminal 28.

이상에서 본 바와 같이, 본 발명에 따른 자동차용 에이비에스 센서에 의하면, 베어링의 외륜에 장착되는 케이스의 내부에 에이비에스 센서의 각 구성품이 설치됨에 따라, 기계적 외부적 충격으로부터 부품을 보호할 수 있고, 기존의 외장형 에이비에스 센서 장착시 사용되는 홀가공이나 브라켓등이 필요없어 장착이 용이하고 비용을 절감할 수 있게 된다. 또한, 기존의 외장형 센서의 경우, 톤휠의 공차, 톤휠의 위치, 센서의 장착위치에 따른 공차등에 의하여 에어갭의 변화가 생길 수 있는 점을 방지할 수 있게 된다.As described above, according to the ABS sensor for automobiles according to the present invention, as each component of the ABS sensor is installed inside the case to be mounted on the outer ring of the bearing, it is possible to protect the components from mechanical external shocks No need for hole processing or bracket used in existing external ABS sensor installation, it is easy to install and reduce cost. In addition, in the case of a conventional external sensor, it is possible to prevent the change in the air gap due to the tolerance of the tone wheel, the position of the tone wheel, the mounting position of the sensor, and the like.

특히, 제로스피드를 검출하고, 출력형태가 구형파이기 때문에 별도의 변환회로가 필요없으며, 회전속도에 따른 출력변화가 작아 ECU와의 신호처리가 용이하게 이루어지게 되어, 결국 에이비에스센서의 성능을 향상시킬 수 있게 된다.In particular, since the zero-speed detection and the output type is a spherical pie, there is no need for a separate conversion circuit. Since the output change according to the rotational speed is small, the signal processing with the ECU is easily performed, thereby improving the performance of the ABS sensor. It becomes possible.
