Description
본 발명은 노면상태 경고장치에 관한 것으로서, 특히 현재차량의 상태 및 현재차량이 주행하는 도로의 상태를 후방의 차량에게 알려주기 위한 노면상태 경고장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road surface warning device, and more particularly to a road surface warning device for informing a rear vehicle of a state of a current vehicle and a state of a road on which the current vehicle travels.
일반적으로 자동차에는 주행의 안전을 위해서 ABS(Anti-skid Brake System : 앤티 스키드 제동장치) 또는 TCS(Traction Control System : 구동력 제어장치) 등을 적용하고 있다. 앤티 스키드 제동장치는 자동차의 제동시 감속도에 따라 차량 중심이 전방으로 이동하여 앞바퀴의 하중은 증가하고, 뒷바퀴의 하중은 감소하는 경향이 생기기 때문에 바퀴가 정지하여 스키드를 일으키면 노면과의 마찰력이 감소함과 동시에 방향성을 잃게 되어 제동성능이 저하되고 불안정한 제동이 된다.In general, for automobiles, ABS (Anti-skid Brake System) or TCS (Traction Control System) is used for driving safety. Anti-skid brake system tends to move the center of the vehicle forward according to the deceleration of the vehicle, which increases the load on the front wheel and decreases the load on the rear wheel. At the same time, the direction is lost and the braking performance is lowered and unstable braking is achieved.
이러한 현상을 방지하기 위하여 모든 바퀴에 제동력을 균일하게 하기 위하여 모든 차륜 또는 추진축에 설치되어 차륜의 회전속도를 감지한 후 감지된 신호를 제어시스템에 입력하여 제어하거나 또는 내부에 마이크로 컴퓨터가 탑재되어 있어서 제동시 각 차륜의 회전수 차이를 계산하여 슬립상태인지 또는 가속상태인지를 판별한 후 그 상태에 따라서 유압제어장치를 조작하게 된다. 예를 들면 슬립율이 일정한 한계를 초과할 때 슬립량과 이미 기억된 슬립량을 비교하여 바퀴가 고착되지 않고 최대 제동효과를 얻는데 필요한 브레이크 압력을 계산한다.In order to prevent this phenomenon, it is installed on all wheels or propulsion shafts to equalize the braking force on all wheels, and after detecting the rotational speed of the wheels, the detected signal is inputted to the control system and the microcomputer is installed inside. When braking, the difference in the number of revolutions of each wheel is calculated to determine whether it is in a slip state or an acceleration state, and the hydraulic control device is operated according to the state. For example, when the slip ratio exceeds a certain limit, the slip amount is compared with the previously stored slip amount to calculate the brake pressure required to obtain the maximum braking effect without the wheels sticking.
이러한 장치의 제어방식에 따라 크게 기계식과 전자 제어식으로 나눌 수 있다.According to the control method of such a device can be divided into mechanical and electronic control.
구동력 제어장치는 눈길, 빙판길 또는 자갈길 등 미끄러지기 쉬운 노면에서 출발과 가속할 때 과잉의 구동력에 의하여 타이어가 공회전하지 않도록 제어하는 것으로, 연료의 분사량, 점화시기, 스로틀 밸브 등을 제어하여 엔진의 출력을 낮추고, 구동력이 적게되도록 하는 방식이 일반적이나 구동륜에 브레이크를 작동시키는 시스템도 있다. 즉, 미끄러지기 쉬운 노면에서 가속성 및 선회 안정성을 향상시키는 슬립컨트롤 기능과 일반도로에서의 주행 중 선회 가속시 자동차의 조향 성능을 향상시키는 트랙제어 기능이 있다.The driving force control device controls the tire not to idle due to excessive driving force when starting and accelerating on slippery roads such as snowy roads, ice roads or gravel roads, and controls the amount of fuel injected, ignition timing, throttle valve, etc. It is common to lower the output and to lower the driving force, but some systems operate the brakes on the driving wheels. That is, there is a slip control function for improving acceleration and turning stability on a slippery road and a track control function for improving steering performance of the vehicle during turning acceleration during driving on a general road.
상기와 같은 기능들을 가지고 있는 자동차는 급출발, 급가속, 급감속, 급제동 또는 선회시에 노면의 상태에 따라서 적절한 제어가 이루어지므로 안전한 주행을 할 수 있다.Cars having the above functions can be safely driven because the appropriate control is made according to the state of the road surface during rapid start, rapid acceleration, sudden deceleration, sudden braking or turning.
그러나, 후방에서 뒤따라오는 자동차 특히, 상기와 같은 ABS 또는 TCS를 장착하지 않은 자동차는 노면의 상태에 대하여 적절한 대응이 어렵게 되는 문제가 있다.However, there is a problem in that a vehicle following from behind, in particular, a vehicle not equipped with the ABS or TCS as described above, becomes difficult to properly cope with the road surface condition.
따라서, 본 발명은 ABS 또는 TCS가 동작할 때 발생되는 신호를 기초로 하여비상등이 점멸되도록 함으로써 후방차량에게 현재 차량의 상태 및 차량의 노면상태를 적시에 파악할 수 있도록 한 노면상태 경고장치를 제공하는 것을 그 목적으로 한다.Accordingly, the present invention provides a road surface warning device that allows the rear vehicle to timely grasp the current state of the vehicle and the road surface condition by causing the emergency light to blink based on a signal generated when the ABS or the TCS is operating. For that purpose.

상기와 같은 목적을 달성하기 위한 본 발명의 노면상태 경고장치는 ABS 또는 TCS의 동작에 따라 제어신호를 출력하는 신호 발생부(1)와, 상기 신호 발생부(1)로부터 발생된 제어신호를 입력으로 하며 비상등 제어신호를 출력하는 ECM 제어부(2)와, 상기 ECM 제어부(2)로부터 출력된 제어신호에 따라 동작하는 비상등(3)으로 이루어진다.The road surface warning apparatus of the present invention for achieving the above object is a signal generator 1 for outputting a control signal in accordance with the operation of the ABS or TCS, and inputs the control signal generated from the signal generator 1 And an ECM control unit 2 for outputting an emergency light control signal, and an emergency light 3 operating in accordance with the control signal output from the ECM control unit 2.
이하, 본 발명에 따른 노면상태 경고장치의 바람직한 실시예를 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the road surface warning device according to the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 노면상태 경고장치를 도시한 블록도로서, ABS 또는 TCS의 동작에 따라 제어신호를 출력하는 신호 발생부(1)와, 상기 신호 발생부(1)로부터 발생된 제어신호를 입력으로 하는 ECM(Electronic Control Unit) 제어부(2)와, 상기 ECM 제어부로부터 발생된 제어신호에 따라 동작하는 비상등(3)으로 이루어진다.1 is a block diagram showing a road surface warning apparatus according to the present invention, a signal generator 1 for outputting a control signal in accordance with the operation of ABS or TCS, and the control signal generated from the signal generator 1 An electronic control unit (ECM) control unit 2 having an input and an emergency light 3 operating according to a control signal generated from the ECM control unit.
상기와 같이 구성된 본 발명에 따른 노면상태 경고장치의 동작원리를 상세히 설명하면 다음과 같다.Referring to the principle of operation of the road surface warning device according to the present invention configured as described above in detail.
먼저, 자동차가 주행중에 급감속, 급제동 또는 급선회를 하게 될 때 ABS 또는 TCS가 동작하게 되면 신호 발생부(1)로부터 제어신호가 출력되고, 상기 제어신호는 ECM제어부(2)에 입력된다. 상기 ECM 제어부(2)는 각종 센서들로부터 정보를 입력받고 상기 입력된 정보를 기초로 해서 각종 회로와 시스템을 동작하도록 하는 반도체 장치로서 엔진제어, 정속 주행장치, 브레이크 계통 및 변속기 제어 등에 사용되는데, 상기 신호 발생부(1)로부터 출력된 신호를 기초로 하여 비상등 점멸신호를 출력하게 된다.First, when the ABS or the TCS is operated when the vehicle suddenly decelerates, suddenly brakes or sharply turns while driving, a control signal is output from the signal generator 1, and the control signal is input to the ECM controller 2. The ECM control unit 2 is a semiconductor device that receives information from various sensors and operates various circuits and systems based on the input information, and is used for engine control, constant speed traveling device, brake system, transmission control, and the like. The emergency light flashing signal is output based on the signal output from the signal generator 1.
상기 ECM 제어부(2)로부터 발생된 비상등 점멸신호는 비상등(3)을 점멸시키게 되는데, 이때 후방차량은 상기 전방 차량으로부터 점멸되는 비상등(3)의 상태를 확인함으로써 전방차량의 현재상태와 노면의 상태를 파악할 수 있게된다. 그러므로 후방차량은 속도를 감소시킴으로서 자동차의 노면으로부터 이탈 및 미끄러짐을 방지하여 안전운행을 할 수 있게 된다.The emergency light blinking signal generated from the ECM control unit 2 causes the emergency light 3 to blink, wherein the rear vehicle checks the state of the emergency light 3 flickering from the front vehicle so that the current state and the state of the road surface of the vehicle ahead. Will be able to grasp. Therefore, the rear vehicle can reduce the speed and prevent the vehicle from falling off and slipping, thereby making it possible to drive safely.
본 실시예에서는 자동차에 ABS 및 TCS가 장착된 차량에 대해서만 적용하였으나 본 발명은 이것에 한정되는 것은 아니다. 즉, 자동차에 ABS만 장착된 경우 ABS 동작시 신호 발생부(1)로부터 제어신호가 출력될 수 있음은 물론이며, 또한 다른예로 TCS만 장착된 차량의 경우에도 상기 신호 발생부(1)로부터 제어신호가 출력될 수 있도록 함은 물론이다.In this embodiment, the present invention is applied only to a vehicle equipped with ABS and TCS, but the present invention is not limited thereto. That is, when only the ABS is mounted on the vehicle, the control signal may be output from the signal generator 1 during the ABS operation. Also, in the case of a vehicle equipped with only the TCS, the signal generator 1 may also be used. Of course, the control signal can be output.
또한, 본 실시예에서는 자동차에 ABS 및 TCS가 장착된 차량, ABS만 장착된 차량, 또는 TCS만 장착된 차량에 대하여 적용하였으나, 본 발명은 이것에 한정되는 것은 아니다. 즉, 상기 ABS 또는 TCS가 장착되지 않은 차량에 대하여도 적용할 수 있음은 물론이다.In addition, in the present embodiment, the present invention is applied to a vehicle equipped with ABS and TCS, a vehicle equipped with ABS only, or a vehicle equipped with only TCS, but the present invention is not limited thereto. That is, of course, it can also be applied to the vehicle is not equipped with the ABS or TCS.
다만, 이때에는 차량의 급감속, 급제동 및 급선회할 때 센서에 의해 검출할 수 있는 장치를 따로 장착함으로써 적용할 수 있음은 물론이다.However, in this case, it is a matter of course that the apparatus can be applied by separately mounting a device that can be detected by the sensor when the vehicle is suddenly decelerated, braked rapidly and rapidly.
상술한 바와 같이 본 발명에 의하면 ABS 또는 TCS 동작시에 비상등을 점멸시켜 주고, 후방차량은 상기 점멸하는 비상등을 적시에 감지하여 전방 차량의 상태 및 전방차량이 주행중인 노면상태를 파악하고 속도를 감속시킴으로써 과속으로 인한 불의의 사고를 미연에 방지할 수 있는 효과가 있다.As described above, according to the present invention, the emergency light flashes during ABS or TCS operation, and the rear vehicle detects the flashing emergency light in a timely manner to grasp the state of the front vehicle and the road surface on which the front vehicle is driving and to reduce the speed. By doing so, it is possible to prevent accidents caused by speeding in advance.
