Description

차량용 타이어의 공기압 감시장치 및 그 방법{Watching Apparatus of Tire Air-Pressure and the Method for the Same}Watching Apparatus of Tire Air-Pressure and the Method for the Same}

본 발명은 차량용 타이어의 공기압 감시장치 및 그 방법에 관한 것으로서, 특히, 각 바퀴의 회전속도 차이와 각 바퀴과 접지된 노면과 차체 사이의 높이 차이가 동시에 정상치를 초과하는 경우, 운전자에게 이상 상황을 경고하는 차량용 타이어의 공기압 감시장치 및 그 방법에 관한 것이다.The present invention relates to a pneumatic pressure monitoring device for a vehicle tire and a method thereof, in particular, when the difference in the rotational speed of each wheel and the height difference between each wheel and the grounded road surface and the vehicle body exceeds the normal value, warning the driver of an abnormal situation. The present invention relates to a pneumatic pressure monitoring device for a vehicle tire and a method thereof.

일반적으로 자동차의 타이어는 레이욘과 나일론 등의 양질의 고무로 형성되고 내부에 적정 수준의 공기압이 충진되어, 엔진의 동력을 전달받아 회전되는 바퀴의 외주에 끼워져 일체로 회전되면서 차체를 지지하고, 주행 중 노면에서의 충격을 흡수하며, 제동 및 구동, 선회시 노면과의 미끄러짐을 방지한다.In general, the tires of automobiles are made of high quality rubber such as rayon and nylon, and filled with a proper level of air pressure, and are inserted into the outer circumference of the wheel that is rotated by the power of the engine to support the body while rotating integrally. It absorbs the impact on the road surface while driving and prevents slippage with the road surface during braking, driving and turning.

그런데, 자동차의 타이어는 각 타이어에 작용되는 차체의 하중 차이 및 노면과 마찰력 차이, 펑크 등의 원인에 의해 각각의 공기압이 다를 수 있는데, 차체가 상대적으로 공기압이 낮은 타이어 측으로 기울어짐으로써 승차감이 떨어지고 차량의 전/후부에 장착된 램프의 조사 위치가 변하여 안전 사고가 발생될 수 있으며, 차체가 운전자의 의도와 상관없이 상대적으로 공기압이 낮은 타이어 측으로 회전될 수 있다.By the way, the tire of the car may have different air pressures due to the difference in the load of the body applied to each tire, the road surface and frictional force, the puncture, etc. The irradiation position of the lamps mounted on the front / rear of the vehicle may be changed to cause a safety accident, and the vehicle body may be rotated to a tire side having a relatively low air pressure regardless of the driver's intention.

따라서, 종래 기술은 도 1에 도시된 바와 같이 타이어의 공기압이 낮을수록 노면과의 접지력이 약하기 때문에 회전 속도가 더 빠른다는 점에 착안하여 각 바퀴에 바퀴의 회전속도를 검출하는 휠 속도센서(2)를 장착하고, 전자제어유닛(4)이 상기 휠 속도센서(2)로부터 검출신호를 입력받아 각 바퀴의 회전 속도 차이를 비교한 후 각 바퀴의 회전 속도 차이가 정상치를 초과한 경우, 경고등(6) 또는 부저 등을 통해 운전자에게 이상 상황을 경고한다.Therefore, the conventional technology is a wheel speed sensor for detecting the rotational speed of the wheel on each wheel, paying attention to the fact that the lower the air pressure of the tire, the lower the traction with the road surface, as shown in FIG. ), The electronic control unit 4 receives the detection signal from the wheel speed sensor 2 and compares the difference in the rotational speed of each wheel, and then the warning light ( 6) Or warn the driver of abnormal situation by buzzer.

그러나, 종래 기술은 차량의 선회시 또는 눈길, 빗길, 요철로 주행 및 급제동시 각 타이어의 공기압과 상관없이 각 타이어의 슬립률의 차이에 의해 각 바퀴의회전속도 차이가 정상치를 초과할 수 있기 때문에 오작동이 발생되기 쉬워 신뢰성이 낮은 문제점이 있다.However, in the prior art, the difference in the rotational speed of each wheel may exceed the normal value due to the difference in slip ratio of each tire regardless of the air pressure of each tire when turning or snowing, raining, uneven driving and braking. There is a problem that malfunction is likely to occur and low reliability.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 각 바퀴의 회전속도 차이와 각 바퀴과 접지된 노면과 차체 사이의 높이 차이가 동시에 정상치를 초과하는 경우, 운전자에게 이상 상황을 경고하는 차량용 타이어의 공기압 감시장치 및 그 방법을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, when the difference in the rotational speed of each wheel and the height difference between each wheel and the grounded road surface and the vehicle body at the same time exceeds the normal value, warning the driver of an abnormal situation An object of the present invention is to provide an air pressure monitoring apparatus for a vehicle tire and a method thereof.

이하, 본 발명의 실시 예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

상기 본 발명에 따른 차량용 타이어의 공기압 감시장치는 앞뒤 4바퀴에 각각 설치되어 바퀴의 회전속도를 감지하는 휠 속도센서(12)와, 앞뒤 4바퀴 측 차체 저면에 각각 설치되어 초음파를 이용하여 바퀴가 접지된 노면과 차체 사이의 수직방향 높이, 즉 차고를 감지하는 차고센서(14)와, 상기 휠 속도센서(12)로부터 신호를 입력받아 각 바퀴의 회전속도 차이를 산출하여 그 산출값을 정상치(A)와 비교하고, 상기 차고센서(14)로부터 신호를 입력받아 각 바퀴 측 차고의 편차를 산출하여 그 산출값을 정상치(B)와 비교하는 전자제어유닛(16)과, 상기 전자제어유닛(16)의 비교 결과가 각 바퀴의 회전속도 차이가 정상치(A)를 초과하고 각 바퀴 측 차고의 편차가 정상치(B)를 초과한 경우, 상기 전자제어유닛(16)에 의해 제어되어 운전자에게 이상 상황, 즉 위험을 경고하는 경고수단(18)을 포함하여 구성된다.The pneumatic pressure monitoring device for a vehicle tire according to the present invention is installed on each of the front and rear four wheels, the wheel speed sensor 12 for detecting the rotational speed of the wheels, and the front and rear four wheels, respectively, are installed on the bottom of the vehicle body, the wheels using ultrasonic waves A height sensor 14 for detecting a height in a vertical direction between the grounded road surface and the vehicle body, that is, a height sensor 12 and a wheel speed sensor 12 are inputted to calculate a difference in the rotational speed of each wheel, and the calculated value is normal. An electronic control unit 16 which compares A) with a signal from the garage sensor 14, calculates the deviation of each wheel side garage, and compares the calculated value with a normal value B; The comparison result of 16) indicates that when the difference in the rotational speed of each wheel exceeds the normal value A and the deviation of each wheel side garage exceeds the normal value B, it is controlled by the electronic control unit 16 to cause an error to the driver. Warning the situation, ie danger It comprises a warning means 18 to.

상기에서, 휠 속도센서(12)는 타이어의 공기압이 낮을수록 바퀴와 그 바퀴가 접지된 노면과의 마찰력이 작아 회전속도가 더 빠르다는 점에 착안하여 어느 한 바퀴의 회전속도가 다른 바퀴의 회전속도보다 비정상적으로 빠른 경우 그 바퀴의 타이어의 공기압이 부족함을 알 수 있도록 한다.In the above, the wheel speed sensor 12, the lower the air pressure of the tire, the smaller the frictional force between the wheel and the road surface where the wheel is ground, so that the rotation speed is faster, the rotation speed of any one wheel is different from the rotation of the wheel If it is abnormally faster than speed, it is possible to know that the tire pressure of the wheel is insufficient.

단, 차량은 선회시, 눈길 또는 빗길에서의 주행시, 급제동시 타이어의 공기압과 상관없이 각 바퀴의 회전속도 차이가 정상치를 초과할 수 있다.However, the vehicle may exceed the normal value of the rotation speed of each wheel regardless of the air pressure of the tire when turning, driving in snow or rain, braking.

상기 차고센서(14)는 타이어의 공기압이 낮음에 따라 각 바퀴가 접지된 노면과 차체 사이의 수직방향 높이, 즉 차고가 낮다는 점에 착안하여 어느 한 바퀴 측 차고가 다른 바퀴 측 차고보다 비정상적으로 낮은 경우 그 바퀴의 타이어의 공기압이 부족함을 알 수 있도록 한다.The garage sensor 14 is an abnormal height than the other wheel-side garage in consideration of the low vertical height, that is, the height between the road surface and the body of each wheel is grounded as the tire air pressure is low If low, the tires on the wheels may be deficient.

상기 전자제어유닛(16)은 각 바퀴의 회전속도 차이가 정상치(A)를 초과하고 각 바퀴 측 차고의 편차가 정상치(B)를 초과한 경우, 적어도 하나 이상의 타이어의 공기압이 다른 타이어의 공기압에 비해 비정상적으로 낮다고 판단하고, 상기 경고수단(18)에 제어신호를 출력한다.The electronic control unit 16, the difference in the rotational speed of each wheel exceeds the normal value (A) and the deviation of the wheel-side garage exceeds the normal value (B), the air pressure of at least one tire to the air pressure of the other tire It is judged that it is abnormally low in comparison with the other, and outputs a control signal to the warning means 18.

상기 경고수단(18)은 운전자의 시야에 잘 보이는 차실의 일측에 장착되어, 상기 전자제어유닛(16)로부터 제어신호가 입력되면 전원이 인가되어 발광되는 경고등으로 이루어진다.The warning means 18 is mounted on one side of the vehicle well visible to the driver's field of view, and when the control signal is input from the electronic control unit 16, power is applied and the warning lamp emits light.

상기와 같이 구성된 본 발명에 따른 차량용 타이어의 공기압 감시방법을 살펴보면 다음과 같다.Looking at the air pressure monitoring method of a vehicle tire according to the present invention configured as described above are as follows.

먼저, 제1 단계에서 상기 휠 속도센서(12)는 각 바퀴의 회전속도를 감지하여 그 속도감지신호를 전자제어유닛(16)에 입력하고, 상기 차고센서(14)는 각 바퀴가 접지된 노면과 차체 사이의 수직방향 높이, 즉 차고를 감지하여 그 차고감지신호를 상기 전자제어유닛(16)에 입력한다. (S1)First, in the first step, the wheel speed sensor 12 detects the rotational speed of each wheel and inputs the speed detection signal to the electronic control unit 16, and the garage sensor 14 has a road surface on which each wheel is grounded. A height in a vertical direction between the vehicle and the vehicle body, that is, a height is sensed, and the height detection signal is input to the electronic control unit 16. (S1)

제2 단계에서 상기 전자제어유닛(16)은 상기 휠 속도센서()로부터 감지된 속도감지신호에 의해 각 바퀴의 회전속도 차이를 산출하여 그 산출값을 정상치(A)와 비교하고, 상기 차고센서(14)로부터 감지된 차고감지신호에 의해 각 바퀴 측 차고의 편차를 산출하여 그 산출값을 정상치(B)와 비교한다.(S2)In the second step, the electronic control unit 16 calculates the difference in the rotational speed of each wheel by the speed detection signal detected from the wheel speed sensor () and compares the calculated value with the normal value (A), and the garage sensor The deviation of each wheel side garage is calculated by the height detection signal detected from (14), and the calculated value is compared with the normal value B. (S2)

그리고, 상기 전자제어유닛(16)은 각 바퀴의 회전속도 차이가 정상치(A)를 초과하고 동시에 차고의 편차가 정상치(B)를 초과한 경우 경고수단(18)에 제어신호를 출력한다. (S3,S4)The electronic control unit 16 outputs a control signal to the warning means 18 when the difference in the rotational speed of each wheel exceeds the normal value A and the deviation of the garage exceeds the normal value B. (S3, S4)

제3 단계에서 상기 경고수단(18)은 상기 전자제어유닛(16)으로부터 제어신호가 입력되면, 전원을 인가받아 발광됨으로써 운전자에게 이상상황, 즉 안전사고가 발생될 수 있음을 경고한다. (S5)In the third step, when the control signal is input from the electronic control unit 16, the warning means 18 warns the driver that an abnormal situation, that is, a safety accident, may be generated by receiving power and emitting light. (S5)

따라서, 본 발명은 타이어의 공기압과 상관없이 차량의 선회시 또는 눈길, 빗길, 요철로 주행 및 급제동시 각 타이어의 슬립률의 차이로 인해 각 바퀴의 회전속도 차이가 정상치(A)를 초과할 수도 있으므로 각 바퀴의 회전속도 차이가 정상치(A)를 초과하더라도, 각 바퀴 측 차고의 편차를 통해 각 바퀴의 회전속도의 차이가 타이어의 공기압 부족으로 인한 결과인지를 보안해주기 때문에 보다 정확한 정보를 갖고 운전자에게 차량용 타이어의 공기압으로 인한 이상상황을 경고함으로써 안전사고 및 그로 인한 인명피해를 방지할 수 있도록 한다.Therefore, the present invention may vary the rotational speed of each wheel exceeds the normal value (A) due to the difference in the slip ratio of each tire at the time of turning or snowy roads, rain, uneven roads and braking regardless of the tire air pressure Therefore, even if the difference in the rotational speed of each wheel exceeds the normal value (A), it is possible to ensure that the difference in the rotational speed of each wheel is the result of the lack of tire pressure through the deviation of the garage on each wheel. By alerting the vehicle to abnormal conditions caused by the inflation pressure of tires, it is possible to prevent safety accidents and human injury.

상기와 같이 구성되는 본 발명에 따른 차량용 타이어의 공기압 감시장치 및 그 방법은 각 바퀴의 회전속도 차이가 정상치를 초과하고, 동시에 각 바퀴 측 차고의 편차가 정상치를 초과한 경우 운전자에게 이상상황을 경고하기 때문에 보다 정확한 정보를 갖고 타어어의 공기압으로 인한 이상상황을 경고함으로써 신뢰성이 높은 이점이 있다.The air pressure monitoring apparatus and method for a vehicle tire according to the present invention configured as described above warn the driver of an abnormal situation when the difference in the rotational speed of each wheel exceeds the normal value and at the same time the deviation of the garage on each wheel exceeds the normal value. Therefore, there is a high reliability by warning the abnormal situation due to the air pressure of the other language with more accurate information.
