Description

자동차의 타이어 공기압 경보장치{tire air pressure alarm system of vehicle}Tire air pressure alarm system of a vehicle

본 발명은 자동차의 타이어 공기압 경보장치에 관한 것으로, 특히 타이어의 공기압을 정확하게 측정하여 주행의 안정성을 확보할 수 있도록 된 자동차의 타이어 공기압 경보장치에 관한 것이다.The present invention relates to a tire inflation pressure warning device for a vehicle, and more particularly, to a tire inflation pressure warning device for a vehicle that can secure driving stability by accurately measuring the air pressure of a tire.

일반적으로, 자동차의 바퀴(10)는 도 1에 도시된 바와 같이 림과 디스크의조합으로 이루어지는 휠(11)과, 이 휠(11)에 끼워져 일체로 회전되면서 중행중 노면에서의 충격을 흡수하는 타이어(12)로 구성된다.In general, the wheel 10 of the vehicle, as shown in Figure 1 and the wheel 11 made of a combination of the rim and the disk, which is fitted to the wheel 11 to rotate integrally to absorb the impact on the road surface in the middle The tire 12 is comprised.

이와 같이, 휠(11)과 타이어(12)로 구성되는 바퀴(10)는 허브볼트(21)와 허브너트(22)의 나사체결에 의해 휠허브(31)에 결합되며, 상기 휠허브(31)에는 허브베어링(32)을 매개로 차축(33)이 결합되는 구조로 되어 있다.As such, the wheel 10 composed of the wheel 11 and the tire 12 is coupled to the wheel hub 31 by screwing the hub bolt 21 and the hub nut 22, and the wheel hub 31. ) Has a structure in which the axle 33 is coupled via the hub bearing 32.

즉, 상기 허브볼트(21)는 휠허브(31)에서부터 바퀴(10)를 구성하는 휠(11)을 관통하여 설치되게 되며, 상기 휠(11)을 관통한 허브볼트(21)의 선단에 허브너트(22)가 나사체결됨으로써 상기 바퀴(10)가 휠허브(31)에 결합되게 되는 것이다.That is, the hub bolt 21 is installed through the wheel 11 constituting the wheel 10 from the wheel hub 31, the hub at the tip of the hub bolt 21 penetrating the wheel 11 The nut 22 is screwed so that the wheel 10 is coupled to the wheel hub 31.

한편, 종래의 타이어 공기압 경보장치는 보통 송신기와 수신기를 이용하는 방법과 ABS시스템의 휠스피드센서를 이용하는 두가지 방법이 주로 사용되고 있다.On the other hand, the conventional tire pressure warning device is mainly used two methods using a transmitter and a receiver and a wheel speed sensor of the ABS system.

즉, 상기 송신기와 수신기를 이용하는 첫 번째 방법은 송신기에서 타이어(12)의 온도 및 압력을 측정하여 수신안테나를 통해 수신기로 전달하면 상기 수신기는 송신기로부터 입력된 값을 운전석에 설치된 공기압표시기로 표시하여 주며 이를 운전자가 인식함으로써 작동되는 장치인데, 이와 같이 타이어의 공기압을 측정하기 위해 송신기와 수신기를 이용하게 되면 전체적인 타이어 공기압 경보장치의 제조원가가 고가제품인 송신기와 수신기로 인해 그만큼 상승되는 문제점이 있었다.That is, the first method using the transmitter and the receiver measures the temperature and pressure of the tire 12 in the transmitter and transmits the received signal to the receiver through the receiving antenna, the receiver displays the value input from the transmitter by the air pressure indicator installed in the driver's seat It is a device that is operated by the driver to recognize this, when using a transmitter and a receiver to measure the air pressure of the tire as described above, there is a problem that the manufacturing cost of the tire pressure warning device as a whole due to the expensive transmitter and receiver.

또한, 상기 송신기와 수신기는 무선시스템으로 운영되기 때문에 타이어 공기압의 측정값이 안정적이지 못하다는 문제점도 있었다.In addition, since the transmitter and the receiver operate in a wireless system, there is a problem that the measured value of the tire pressure is not stable.

이에 따라, 상기와 같은 문제점을 해소하기 위해 ABS시스템의 휠스피드센서를 이용하는 두 번째 방법이 주로 사용되는데, 이 장치는 전자제어유니트(ECU)의 로직(Logic)만 추가하여 기존의 ABS시스템을 그대로 사용하게 됨으로써 제조원가가 절감된다는 장점과 아울러 유선을 이용하여 운영되기 때문에 타이어 공기압의 측정값이 송신기와 수신기를 사용하던 장치보다는 안정적이라는 장점은 있으나, 이 장치는 타이어(12)의 공기압을 측정할 때 절대압을 측정하는 것이 아니라 각각의 타이어 공기압을 비교하는 방식 즉 4개의 타이어(12)의 공기압을 서로 상대적으로 비교하는 방식으로 측정하도록 되어 있어 측정된 값에 오류가 빈번하게 발생된다는 문제점이 여전히 남아 있게 되었다.Accordingly, in order to solve the above problems, the second method using the wheel speed sensor of the ABS system is mainly used, and this device adds only the logic of the electronic control unit (ECU) to keep the existing ABS system. In addition, the manufacturing cost is reduced by using, and since the tire is operated by wire, the measured value of the tire inflation pressure is more stable than the device using the transmitter and the receiver. However, the device measures the inflation pressure of the tire 12. Instead of measuring the absolute pressure, the tire tires are measured by comparing the tire pressures of each tire, that is, by comparing the tire pressures of the four tires 12 with each other. Thus, there is still a problem that errors occur frequently in the measured values. It became.

이에 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 타이어의 공기압을 측정하는 센서를 휠스피드센서의 측부에 일체로 장착시켜 절대압 방식으로 타이어의 공기압을 측정하고 측정된 값을 유선을 이용하여 운전석에 장착된 경보표시기로 표시하도록 함으로써, 비교적 정확한 타이어의 공기압을 측정할 수 있음은 물론, 이로 인해 주행의 안정성을 확보할 수 있도록 된 자동차의 타이어 공기압 경보장치를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, by integrally mounting a sensor for measuring the air pressure of the tire integrally to the side of the wheel speed sensor to measure the air pressure of the tire in an absolute pressure method and using the measured value wired By displaying the alarm indicator mounted on the driver's seat, it is possible to measure a relatively accurate air pressure of the tire, and to provide a tire air pressure warning device of the vehicle that can thereby ensure the stability of the driving.
