Abstract

PURPOSE: A speed limiting device is provided to prevent an accident by limiting the traveling speed of a vehicle when a difference of air pressures in tires is generated. CONSTITUTION: A speed limiter comprises a tire air pressure detecting sensor(10) to detect air pressures of each tire; an ECU(Electronic Control Unit)(20) to calculates a difference of the air pressures and to output a limiting signal of speed according to the calculated difference; and a speed limiting throttle valve(33) to limit the speed of a vehicle by controlling an amount of mixed air in an engine. The control signal is outputted into a magnetic valve(31) when the difference of air pressures is over a predetermined reference value. The magnetic valve(31) is opened and air pressure of an actuator(32) is increased by an air tank(1). The actuator(32) generates rotating force and the amount of mixed air is reduced by controlling an opening angle of the speed limiting throttle valve(33). Thereby, the speed of the vehicle is reduced and the vehicle is not accelerated anymore.

Description

타이어 에어압 차에 따른 속도 제한 장치Speed limiter according to tire air pressure difference

본 발명은 타이어 에어압 차에 따른 속도 제한 장치에 관한 것으로, 상세하게는 각 구동 휠의 타이어 에어압 차가 발생되면 차량의 주행 속도를 제한하도록 한 타이어 에어압 차에 따른 속도 제한 장치에 관한 것이다.The present invention relates to a speed limiting device according to a tire air pressure difference, and more particularly, to a speed limiting device according to a tire air pressure difference to limit the traveling speed of a vehicle when a tire air pressure difference of each driving wheel is generated.

일반적으로 타이어는 레이온이나 나일론 등의 섬유를 발 모양으로 만든 것을 양질의 고무로 천 모양으로 하여 이것을 겹치게 성형하여 휠에 일체가 되게 끼워진다.In general, tires are made of fibers such as rayon or nylon in the shape of feet, which are made of high quality rubber into a cloth shape, and overlapped with each other to be integrally fitted to the wheels.

그 기능은 노면에서의 충격을 흡수함과 동시에 제동과 구동 및 선회 시에는 노면과의 슬립을 최소화한다.Its function absorbs shock from the road and minimizes slippage with the road during braking, driving and turning.

또, 타이어의 적절한 에어압은 작은 진동을 흡수하여 승차감이 좋게 하고 차고를 일정하게 하며 차량의 추진력 향상과 주행 안전성 및 안락한 승차감을 가져다준다.In addition, the proper air pressure of the tire absorbs a small vibration to improve the ride comfort, to make the garage constant, and to improve the driving force of the vehicle, driving safety and comfortable riding comfort.

그러나, 타이어의 에어압이 일정 이하로 저하되거나 펑크시에는 타이어가 제 기능을 발휘하지 못하므로 승차감 및 추진력이 떨어지고 주행 안전성이 저하된다.However, when the tire air pressure is lowered below a certain level or when the tire is punctured, the tire does not function properly, resulting in poor riding comfort and driving force and deterioration in driving safety.

특히, 차량의 고속 주행시 각 구동 휠의 타이어 에어압 차가 발생되면 주행 안전성이 극도로 저하되어 사고가 유발될 수 있는 문제점이 있었다.In particular, when a tire air pressure difference of each driving wheel is generated during a high speed driving of a vehicle, there is a problem in that driving safety is extremely reduced and an accident may be caused.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 각 구동 휠의 타이어 에어압 차가 발생되면 차량의 주행 속도를 제한함으로써, 각 구동 휠의 타이어 에어압 차로 주행 안전성이 저하되어 차량의 주행중 특히, 고속 운행중에 유발 가능성이 높은 사고의 위험성을 해소하는데 그 목적이 있다.The present invention has been made to solve the above problems, by limiting the running speed of the vehicle when the tire air pressure difference of each drive wheel is generated, driving safety of the tire air pressure difference of each drive wheel is reduced, especially during driving of the vehicle, The purpose is to eliminate the risk of accidents that are likely to occur during high speed operation.

도 1은 본 발명의 실시예에 따른 타이어 에어압 차에 따른 속도 제한 장치의 구성도이다.1 is a block diagram of a speed limiting device according to a tire air pressure difference according to an embodiment of the present invention.

본 발명의 상기 에어압 감지수단은 메탈 휠에 장착되어 타이어의 에어압에 따라 달라지는 자성의 극성을 차체측에 고정되어 있는 홀(hall)소자로 감지하는 타이어 에어압 감지 센서(10)로 구성된다.The air pressure detecting means of the present invention is composed of a tire air pressure sensor (10) mounted on the metal wheel for detecting the polarity of the magnetic depending on the air pressure of the tire with a hall element fixed to the vehicle body side .

또, 상기 에어압 차 판단수단은 상기 타이어 에어압 감지 센서(10)를 입력단에 접속한 마이크로 컴퓨터(μ-com)가 내장된 전자 제어 유니트(electronic control unit)(ECU)(20)로 구성된다.In addition, the air pressure difference determining means is composed of an electronic control unit (ECU) 20 in which a microcomputer (μ-com) connecting the tire air pressure detecting sensor 10 to an input terminal is incorporated. .

상기 차속 제한수단은 에어 탱크(1)의 에어 배출구상에 설치되며 상기 전자 제어 유니트(20)의 출력 신호에 의하여 개폐되는 마그네틱 밸브(31)와, 상기 에어 탱크(1)의 에어 배출로에 연결되며 에어압의 증감에 따라 회전력이 발생되는 회전형 엑추에이터(32)와, 엔진의 혼합기 흡입로(2)상에 설치되며 상기 엑추에이터(32)의 회전력에 의하여 개폐되는 차속 제한 스로틀 밸브(33)로 구성된다.The vehicle speed limiting means is installed on an air outlet of the air tank 1 and connected to a magnetic valve 31 which is opened and closed by an output signal of the electronic control unit 20 and an air outlet of the air tank 1. And a rotational actuator 32 having a rotational force generated according to the increase or decrease of air pressure, and a vehicle speed limiting throttle valve 33 installed on the mixer intake passage 2 of the engine and opened and closed by the rotational force of the actuator 32. It is composed.

도면 중 미설명 부호인 3은 운전자에 의하여 구동되는 엑셀러에이터 페달이고, 4는 상기 엑셀러에이터 페달(3)과 연동되어 개폐되는 스로틀 밸브이다.In the drawings, reference numeral 3 denotes an accelerator pedal driven by a driver, and 4 denotes a throttle valve which is opened and closed in cooperation with the accelerator pedal 3.

이하, 본 발명의 타이어 에어압 차에 따른 속도 제한 장치의 작용을 도면에 도시된 실시예에 기초하여 설명한다.Hereinafter, the operation of the speed limiting device according to the tire air pressure difference of the present invention will be described based on the embodiment shown in the drawings.

차량이 운행되면 메탈 휠에 장착된 타이어 에어압 감지 센서(10)는 타이어의 에어압에 따라 달라지는 자성의 극성을 차체측에 고정되어 있는 홀(hall)소자로 수시로 감지하여 전자 제어 유니트(20)에 입력한다.When the vehicle is driven, the tire air pressure sensor 10 mounted on the metal wheel frequently detects the polarity of the magnetic body depending on the air pressure of the tire as a hall element fixed to the side of the vehicle, and thereby controls the electronic control unit 20. Type in

상기 전자 제어 유니트(20)는 상기 타이어 에어압 감지 센서(10)의 감지값이 입력되면 이를 비교하여 각 구동 휠 타이어간의 에어압 차를 산출한다.The electronic control unit 20 calculates an air pressure difference between each driving wheel tire by comparing the detected value of the tire air pressure sensor 10 with the input.

이때, 에어압 차가 미리 세팅된 기준값(허용 에어압 차와 오차를 감안한 설정값)보다 크면 산출된 에어압 차에 따라 마그네틱 밸브(31)에 차속 제한 신호 즉, 제어 전류가 출력된다.At this time, when the air pressure difference is larger than the preset reference value (a set value considering the allowable air pressure difference and the error), the vehicle speed limit signal, that is, the control current is output to the magnetic valve 31 according to the calculated air pressure difference.

이에, 상기 마그네틱 밸브(31)가 제어 전류에 의하여 개방되므로 에어 탱크(1)에 의하여 엑추에이터(32)의 에어압이 증압된다.Accordingly, since the magnetic valve 31 is opened by the control current, the air pressure of the actuator 32 is increased by the air tank 1.

상기 엑추에이터(32)는 에어압의 증압에 따라 회전력을 발생시키며 엔진의 혼합기 흡입로(2)상에 설치된 차속 제한 스로틀 밸브(33)의 개폐각이 조절되어 엔진에 흡입되는 혼합기의 량이 감소된다.The actuator 32 generates a rotational force according to the increase in air pressure, and the opening and closing angle of the vehicle speed limit throttle valve 33 installed on the mixer intake passage 2 of the engine is adjusted to reduce the amount of the mixer sucked into the engine.

그러므로, 차량의 속도가 감속되며 운전자가 엑셀러에이터 페달(3)을 구동하더라도 차량은 더 이상 가속되지 않는다.Therefore, the speed of the vehicle is decelerated and the vehicle is no longer accelerated even if the driver drives the accelerator pedal 3.

상술한 바와 같이 본 발명의 타이어 에어압 차에 따른 속도 제한 장치는, 각 구동 휠의 타이어 에어압 차가 발생되면 차량의 주행 속도를 제한함으로써, 각 구동 휠의 타이어 에어압 차로 주행 안전성이 저하되어 차량의 주행중 특히, 고속 운행중에 유발 가능성이 높은 사고의 위험성이 해소되는 효과가 있다.As described above, the speed limiting device according to the tire air pressure difference of the present invention limits the traveling speed of the vehicle when the tire air pressure difference of each driving wheel is generated, whereby driving safety of the tire air pressure difference of each driving wheel is lowered and the vehicle is reduced. There is an effect that the risk of accidents that are likely to occur during high-speed driving, in particular, is eliminated.
