차량의 좌우구배인식에 의한 도어개폐시스템{Door open/close system for compensating the door open/close power as the state of the car incline}Door open / close system for compensating the door open / close power as the state of the car incline}

본 발명은 차량의 좌우구배인식에 의한 도어개폐시스템에 관한 것으로서, 더욱 구체적으로는 차량이 좌우의 높이가 서로 다른 도로에 주정차하고 탑승객이 하차하는 경우에 발생되는 차량 횡방향 구배에 따른 도어개폐의 어려움을 해소하기 위한 차량의 좌우구배인식에 의한 도어개폐시스템에 관한 것이다.The present invention relates to a door opening and closing system according to the right and left gradient of the vehicle, and more particularly to the door opening and closing according to the lateral gradient of the vehicle generated when the vehicle parks on a road having different left and right heights and the passengers get off. It relates to a door opening and closing system by the left and right gradient recognition of the vehicle to solve the difficulty.

차량의 주정차 환경은 일정하지 않으며, 평탄한 도로 뿐만 아니라 언덕과 같은 경사로에 주정차하는 경우가 자주 발생된다. 이러한 경사로에서는 탑승객이 하차하기 위하여 차량도어를 열어 줄 때 차량도어의 자중에 의하여 도어를 열기 어려운 불편함이 있다. 특히 차량의 횡방향의 좌우구배가 다른 도로에 주, 정차하는 경우에는 차량의 횡방향 구배에 따른 차량도어의 하중이동에 의하여 원활하게 차량도어를 열고 닫기 힘든 현상이 발생된다.The parking environment of the vehicle is not constant, and parking often occurs on hills such as hills as well as on flat roads. In such a ramp, it is difficult to open the door by the weight of the vehicle door when the passenger opens the vehicle door to get off. In particular, when the vehicle is parked and stopped on a road in which the lateral gradient of the vehicle is different from each other, it is difficult to open and close the vehicle door smoothly by the load movement of the vehicle door according to the lateral gradient of the vehicle.

예를 들어, 차량이 조수석으로 기울어지면, 즉 차량이 오른쪽(Rihgt Hnad)으로 경사지면, 운전석에서 차량도어를 열 때 도어하중에 의하여 힘이 들며, 닫을 때에는 너무 빠른 속도로 닫혀서 손가락 끼임등에 의한 부상을 입을 염려가 있다. 이와는 반대의 구배(왼쪽(LH)으로 경사짐)를 가지는 도로에 주정차할 때에는 조수석측(우측) 도어에 동일한 현상이 발생된다. For example, if the vehicle is inclined to the front passenger seat, that is, the vehicle is inclined to the right (Rihgt Hnad), the door load is applied when the vehicle door is opened from the driver's seat, and when the vehicle is closed, it is closed at a too fast speed and injuries due to pinching There is a risk to wear. The same phenomenon occurs on the passenger seat side (right) door when parking on a road having the opposite gradient (beveled to the left LH).

또한 운전석에서 차량도어를 열 때에는 너무 빨리 열려서 차량도어가 바깥쪽 벽등에 부딪혀 차량의 손상이 발생되기도 하며, 닫을 때에는 많은 힘을 들여서 잡아당겨야 하는 경우가 발생되고 있다.In addition, when the vehicle door is opened from the driver's seat, the vehicle door is opened too quickly and the vehicle door hits the outer wall, resulting in damage to the vehicle.

그러나 종래 차량에는 주정차시에 차량의 횡방향 좌우구배에 따른 안전장치가 설치되어 있지 않아서 탑승객의 불만을 사고 있는 형편이다.However, the conventional vehicle is not equipped with a safety device according to the lateral left and right gradients of the vehicle at the time of parking, which is a situation for the passenger's complaints.

본 발명은 상기한 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 차량이 좌우의 높이가 서로 다른 도로에 주정차하고 탑승객이 하차하는 경우에 발생되는 차량 횡방향 구배에 따른 도어개폐의 어려움을 해소하기 위한 차량의 좌우구배인식에 의한 도어개폐시스템을 제공하는데 있다.The present invention is to solve the above problems, an object of the present invention is to solve the difficulty of opening and closing the door according to the vehicle lateral gradient generated when the vehicle is parked on a road with different left and right heights and the passengers get off. To provide a door opening and closing system by the left and right gradient recognition of the vehicle.

본 발명의 다른 목적은 차량의 안전기능을 높임으로서 소비자에게 만족감을 주고 차량의 부가가치를 높일 수 있는 차량의 좌우구배인식에 의한 도어개폐시스템을 제공하는데 있다.Another object of the present invention to provide a door opening and closing system by the left and right gradient recognition of the vehicle to increase the safety function of the vehicle to the customer satisfaction and increase the added value of the vehicle.

상기 목적을 달성하기 위한 본 발명의 차량의 좌우구배인식에 의한 도어개폐시스템은, 차량용 도어체커의 내측단부에 형성되는 것으로 작동레일을 포함하는 도어체커 연장부; 상기 도어체커 연장부의 작동레일에 형합되는 구동기어가 축설된 구동모터; 상기 도어체커의 외측단부에 설치되는 것으로 차량도어의 위치 및 열림상태를 검출하기 위한 도어열림측정부; 차량의 횡방향의 좌우구배를 인식하기 위한 차량구배인식부; 및 상기 도어열림측정부로부터 입력되는 도어열림정보와 상기 차량구배인식부로부터 입력되는 좌우구배정보를 이용하여 구배 및 도어열림상태에 따라서 상기 구동모터의 회전방향을 제어하여 차량도어의 개폐상태를 제어하기 위한 제어부를 포함하는 것을 특징으로 한다.The door opening and closing system according to the left and right gradient recognition of the vehicle of the present invention for achieving the above object is formed on the inner end of the door checker for the vehicle door checker extension portion including an operation rail; A drive motor in which a drive gear is fitted to the operation rail of the door checker extension; A door opening measuring unit installed at an outer end of the door checker to detect a position and an opening state of the vehicle door; A vehicle gradient recognition unit for recognizing left and right gradients in a lateral direction of the vehicle; And controlling the opening and closing state of the vehicle door by controlling the rotation direction of the driving motor according to the grade and door opening state by using the door opening information input from the door opening measuring unit and the left and right gradient information input from the vehicle gradient recognition unit. It characterized in that it comprises a control unit for.

이하 첨부된 도면을 참고하여 본 발명의 차량의 좌우구배인식에 의한 도어개폐시스템을 상세히 설명하면 다음과 같다.Hereinafter, a door opening and closing system according to left and right gradient recognition of a vehicle of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 차량의 횡방향 좌우구배에 따라서 차량도어를 열어줄 때 발생되는 문제점을, 차량에 기장착된 도어체커의 단부를 연장하고 모터로 구동되는 레일을 형성하여, 도어의 개폐시에 모터의 구동력을 이용한 역구동 또는 배력구동을 하는 기능을 추가함으로서 탑승객이 쉽고 안전하게 도어를 열고 닫을 수 있도록 구성한 것이다.The present invention is to solve the problem that occurs when opening the vehicle door according to the lateral left and right gradient of the vehicle, by extending the end of the door checker mounted on the vehicle and forming a rail driven by the motor, By adding the function of reverse driving or power driving using driving force, passengers can open and close the door easily and safely.

먼저 도 1을 참고하여 종래 사용되는 도어체커의 구조를 살펴 보면 다음과 같다. 도시된 바와 같이, 도어체커(6)는 차체(2)에 일단부가 이동불가능하게 고정되고 타단부는 차량도어(4)의 내측으로 이동가능하게 설치된다. 차량도어(4)가 열리게 되면 도어체커(6)가 차량도어(4)의 내부로부터 외부로 노출되면서 연장되며 완전히 열리게 되면 내부에 설치된 스톱퍼에 의하여 정지된다. 따라서 차량도어(4)의 열림각이 제한된다.First, referring to FIG. 1, the structure of a door checker conventionally used is as follows. As shown, the door checker 6 is fixed to the vehicle body 2 so that one end thereof is immovably fixed, and the other end thereof is movable to the inside of the vehicle door 4. When the vehicle door 4 is opened, the door checker 6 extends while being exposed to the outside from the inside of the vehicle door 4, and when fully opened, the door checker 6 is stopped by a stopper installed therein. Therefore, the opening angle of the vehicle door 4 is limited.

상기와 같은 종래 도어체커(6)에, 본 발명에 의하면, 차량도어(4)의 내측으로 연장된 개방단부에 도어체커 연장부가 형성된다. 도 2는 본 발명에 의한 도어체커(6)의 장착상태를 나타내는 개략적인 사시도이다. 도어체커(6)의 일단부는 차체장착부(2a)에 고정되고 타단부는 차량도어(4)에 장착된 도어마운팅부(4a)를 관통하여 내부로 삽입되어 있다. 차량도어(4)가 닫히면 도어체커(6)는 전부 차량도어(4)의 내부로 삽입된다.In the conventional door checker 6 as described above, according to the present invention, a door checker extension part is formed at an open end extending inwardly of the vehicle door 4. 2 is a schematic perspective view showing a mounting state of the door checker 6 according to the present invention. One end of the door checker 6 is fixed to the vehicle body mounting portion 2a, and the other end is inserted into the vehicle mounting portion 4a through the door mounting portion 4a mounted on the vehicle door 4. When the vehicle door 4 is closed, all the door checkers 6 are inserted into the vehicle door 4.

상기와 같은 도어체커(6)의 단부는 내측으로 더욱 연장되어서 도어체커 연장부(10)가 형성되며, 상기 도어체커 연장부(10)에는 작동레일(12)이 형성된다. 상기 작동레일(12)은 도면에 표시된 것과 같이, 도어체커 연장부(10)의 내부에 양면으로 형성되거나 또는 상부 또는 하부면의 일면에만 형성될 수 있다.The end of the door checker 6 as described above further extends inward to form a door checker extension 10, and an operation rail 12 is formed in the door checker extension 10. As shown in the drawing, the operation rail 12 may be formed on both sides of the door checker extension 10 or only on one surface of the upper or lower surface.

상기 작동레일(12)은 구동기어(16)와 형합된다. 한편, 상기 구동기어(16)는 구동모터(14)의 축에 설치되어 있다. 따라서 구동모터(14)가 회전하면 회전하는 방향에 따라서 구동기어(16)가 회전하면서 작동레일(12)을 전후이동시키고 이에 따라서 도어체커(6)가 힘을 받게 된다. 이렇게 도어체커(6)가 힘을 받음으로써 차량도어(4)의 열림이나 닫힘을 용이하게 한다.The actuation rail 12 is mated with the drive gear 16. On the other hand, the drive gear 16 is provided on the shaft of the drive motor (14). Accordingly, when the driving motor 14 rotates, the driving gear 16 rotates along the direction of rotation, and the moving rail 12 is moved back and forth. Accordingly, the door checker 6 receives a force. In this way, the door checker 6 receives the force to facilitate the opening or closing of the vehicle door 4.

상기 구동모터(14)는 제어부(18)와 연결되어 있으며, 제어부(18)로부터 출력되는 제어신호에 따라서 회전방향이 제어된다. 상기 제어부(18)는 종래 차량에 장착된 ECU를 이용할 수 있다. 또한 상기 구동모터(14)의 회전방향은 차량의 좌우구배에 따라서 결정되며, 이러한 목적을 위하여 차량구배인식부(26)를 이용하여 검출하며 이것이 후에 상세히 설명된다.The drive motor 14 is connected to the control unit 18, the rotation direction is controlled according to the control signal output from the control unit 18. The controller 18 may use an ECU mounted on a conventional vehicle. The rotational direction of the drive motor 14 is also determined according to the left and right gradients of the vehicle, for which purpose it is detected using the vehicle gradient recognition section 26, which will be described in detail later.

본 발명에 의하면, 또한 차체장착부(2a)에 인접한 도어체커(6)의 표면에 도어열림측정부(20)가 설치된다. 상기 도어열림측정부(20)는 도어의 위치(운전석 또는 조수석측)와 각 도어의 열림 또는 담힘상태를 검출하여 제어부(18)에 입력하기 위한 것이다. 차량의 구배와 도어의 열림상태검출에 의하여 차량도어(4)에 가해지는 배력의 방향 및 강도가 결정된다.According to the present invention, the door opening measuring unit 20 is further provided on the surface of the door checker 6 adjacent to the vehicle body mounting portion 2a. The door opening measuring unit 20 detects the position of the door (the driver's seat or the passenger's seat side) and the open or closed state of each door and inputs it to the controller 18. The direction and the strength of the force applied to the vehicle door 4 are determined by the gradient of the vehicle and the detection of the open state of the door.

도 3은 상기 도어열림측정부(20)의 개략도이다. 도어열림측정부(20)는 도어체커(6)의 표면에 장착되는 가변저항(24)과 상기 가변저항(24)의 변화상태를 검출하기 위한 로드(22)로 구성되며, 각각 제어부(18)에 연결된다. 3 is a schematic diagram of the door opening measuring unit 20. The door opening measuring unit 20 includes a variable resistor 24 mounted on the surface of the door checker 6 and a rod 22 for detecting a change state of the variable resistor 24, respectively, the control unit 18. Is connected to.

본 발명에 의한 제어부(18)는 상기 가변저항(24)과 로드(22)로 구성된 도어열림측정부(20)로부터 입력되는 아날로그신호를 디지탈신호로 변환하는 A/D변환기를 포함하고 있다.The control unit 18 according to the present invention includes an A / D converter for converting an analog signal input from the door opening measuring unit 20 including the variable resistor 24 and the rod 22 into a digital signal.

로드(22)는 고정된 상태이며 도어체커(6)가 열림 또는 닫힘에 따라서 가변저항(24)과의 접촉점이 변경되면서 변경된 가변저항에 따른 전압값이 제어부(18)에 입력되어서 열림 또는 닫힘상태를 판단한다. The rod 22 is fixed and the contact point with the variable resistor 24 is changed as the door checker 6 is opened or closed, so that the voltage value according to the changed variable resistor is input to the controller 18 to open or close it. Judge.

예를 들어서, 일정한 입력전압값(통상 5V)이 인가되는 상태에서, 차량도어(4)가 닫힌 상태에서 열리게 되면 저항값은 증가하게 되며 열린 상태에서 닫히게 되면 저항값이 감소하게 되며 이에 따라서 출력전압값이 변화하게 된다. 제어부(18)에서는 이러한 출력전압값의 변화상태를 이용하여 차량도어(4)의 열림/닫힘 상태를 판단하게 된다.For example, when a constant input voltage value (typically 5V) is applied, the resistance value increases when the vehicle door 4 is opened in the closed state, and the resistance value decreases when the vehicle door 4 is closed in the open state. The value will change. The controller 18 determines the open / closed state of the vehicle door 4 by using the change state of the output voltage value.

한편, 차량의 구배를 검출하기 위한 차량구배인식부(26)는 도 4a 및 도 4b에 도시된 바와 같이, 상단부가 회동가능하게 고정된 로드(32)와, 상기 로드(32)의 하단부에 결합된 평형추(28)와, 상기 로드(32)와 접촉되며 부채꼴 형태를 가지는 가변저항(30)으로 구성된다. On the other hand, the vehicle gradient recognition unit 26 for detecting the gradient of the vehicle is coupled to the rod 32, the upper end is rotatably fixed, as shown in Figures 4a and 4b, the lower end of the rod 32 The counterweight 28 is provided, and the variable resistor 30 is in contact with the rod 32 and has a fan shape.

차량이 수평한 도로에 주정차하게 되면 상기 평형추(28)가 도로면에 대하여 수직방향으로 정중앙에 위치하게 되며, 또한 좌우구배에 따라서 평형추(28)는 좌측 또는 우측으로 이동하고 이에 따라서 발생되는 출력전압값이 변화하므로 역시 좌우구배를 인식할 수 있다. 상기 가변저항(30)과 로드(32)는 제어부(18)에 연결된다. 도 4b는 차량이 좌측(LH) 하방을 향하여 경사진 상태에서의 차량구배인식부(26)의 로드(32) 작동상태를 가리킨다. When the vehicle stops on a horizontal road, the counterweight 28 is located at the right center in the vertical direction with respect to the road surface, and the counterweight 28 moves to the left or the right according to the left and right gradients and is generated accordingly. Since the output voltage changes, left and right gradients can also be recognized. The variable resistor 30 and the rod 32 are connected to the controller 18. 4B shows the operating state of the rod 32 of the vehicle gradient recognition section 26 in a state where the vehicle is inclined downward toward the left LH.

상기와 같은 구성을 가진 본 발명의 차량의 좌우구배인식에 의한 도어개폐시스템의 제어부 작동상태를 도 5의 흐름도를 이용하여 설명하면 다음과 같다.The operation of the control unit of the door opening and closing system by the left and right gradient recognition of the vehicle of the present invention having the above configuration will be described with reference to the flowchart of FIG. 5.

본 발명의 장치는 통상 차량이 주정차한 상태에서 수행되는 것이 바람직하다. 차량이 주정차한 상태에서 차량구배인식부(26)에서는 차량의 좌우구배를 판단한다. 이 때 소정의 임계치(일정구배)를 둠으로서 차량도어(4)의 작동에 별지장이 없는 구배에서 본 발명의 시스템이 작동하는 것을 방지한다.It is preferable that the apparatus of the present invention is usually performed while the vehicle is stopped. The vehicle gradient recognition unit 26 determines the left and right slopes of the vehicle while the vehicle is stopped. At this time, by setting a predetermined threshold (constant gradient), the system of the present invention is prevented from operating in a gradient in which the operation of the vehicle door 4 is not disturbed.

현재의 좌 또는 우구배가 임계치를 초과하면, 제어부(18)는 도어열림측정부(20)를 통하여 운전석측 또는 조수석측중의 어느 차량도어가 작동되는 가를 판단하게 된다. 이것은 차량의 좌 또는 우측 구배에 따라서 열림/닫힘 상태가 서로 다르기 때문이다. If the current left or right gradient exceeds the threshold, the control unit 18 determines through the door opening measuring unit 20 which vehicle door in the driver's seat or the passenger seat side is operated. This is because the open / closed states are different according to the left or right gradient of the vehicle.

먼저 배력구동은 차량도어가 열리거나 닫힐 때 힘을 가하는 방향으로 구동모터가 회전하는 것으로 가정하고, 역구동은 열리거나 닫힐 때 힘을 반대방향으로 가하도록 구동모터가 회전하는 것으로 가정한다. First, the driving force assumes that the drive motor rotates in the direction of applying force when the vehicle door is opened or closed, and the reverse drive assumes that the drive motor rotates to apply force in the opposite direction when the vehicle door is opened or closed.

또한 본 발명의 상기 설명에서는 하나의 도어체커(6)에만 본 발명의 시스템이 적용된 것으로 설명되었지만, 각각의 차량도어 모두에 동일하게 적용될 수 있으며, 다만, 제어부(18)는 하나만을 이용하여 구성할 수 있음은 명백하다. In addition, in the above description of the present invention, it has been described that the system of the present invention is applied to only one door checker 6, but may be equally applied to all of the vehicle doors, but the control unit 18 may be configured using only one. It is obvious.

따라서 하기의 설명에서는 각각의 차량도어의 도어체커(6)에 상기 도어열림측정부(20)와 연장부(10)와 구동모터(14)가 설치되어서 제어부(18)에 의하여 제어되는 것으로 가정한다.Therefore, in the following description, it is assumed that the door opening measuring unit 20, the extension unit 10, and the driving motor 14 are installed in the door checker 6 of each vehicle door and controlled by the control unit 18. .

우측이 높은 상태의 구배, 즉 왼쪽으로 경사진 상태(LH)에서, 도어열림측정부(20)에 의하여, 운전석측 차량도어가 열리는 것으로 판단되면, 차량도어가 천천히 열리도록 역구동 제어신호를 출력한다. 이것은 우측이 높고 좌측이 낮은 구배에서는 운전석측의 차량도어는 급하게 열리고 닫히기 힘들기 때문에 이에 대한 보정력을 가하기 위한 것이다. 한편, 운전석측 차량도어가 닫히는 것으로 판단되면 쉽게 닫히도록 배력구동을 실시한다.If the right side is in a high state, that is, the state inclined to the left (LH), the door opening measuring unit 20 determines that the driver's side vehicle door is opened, and outputs a reverse drive control signal so that the vehicle door is opened slowly. do. This is to apply the correction force to the driver's side door door is difficult to open and close quickly in the high right and low left gradient. On the other hand, if it is determined that the driver's side vehicle door is closed, a back-up driving is performed so as to close easily.

또한 도어열림측정부(20)에 의하여, 조수석측 차량도어가 열리는 것으로 판단되면, 쉽게 열리도록 배력구동을 수행한다. 또한 조수석측 도어가 닫히는 것으로 판단되면 천천히 닫히도록 역구동을 수행한다.In addition, if it is determined by the door opening measuring unit 20 that the passenger-side vehicle door is opened, the driving force is performed to be easily opened. In addition, if it is determined that the passenger side door is closed, the reverse drive is performed to close slowly.

한편, 좌측이 높은 상태의 구배, 즉 오른쪽으로 경사진 상태(RH)에서, 도어열림측정부(20)에 의하여, 운전석측 차량도어가 열리는 것으로 판단되면, 차량도어가 쉽게 열리도록 배력구동 제어신호를 출력한다. On the other hand, in a state in which the left side is in a high state, that is, in a state inclined to the right (RH), if it is determined by the door opening measuring unit 20 that the driver's side vehicle door is opened, the power driving control signal so that the vehicle door is easily opened. Outputs

이것은 좌측이 높고 우측이 낮은 구배에서는 운전석측의 차량도어는 천천히 열리고 급하게 닫히기 때문에 이에 대한 보정력을 가하기 위한 것이다. 한편, 운전석측 차량도어가 닫히는 것으로 판단되면, 천천히 닫히도록 역구동을 실시한다.This is to apply the correction force because the vehicle door on the driver's side opens slowly and closes quickly in the high left and low right gradients. On the other hand, if it is determined that the driver's side vehicle door is closed, reverse driving is performed so as to close slowly.

또한, 도어열림측정부(20)에 의하여 조수석측 차량도어가 열리는 것으로 판단되면, 천천히 열리도록 역구동을 수행한다. 또한 조수석측 도어가 닫히는 것으로 판단되면 쉽게 닫히도록 배력구동을 수행한다. In addition, if it is determined that the passenger seat side vehicle door is opened by the door opening measuring unit 20, the reverse driving is performed to open slowly. In addition, if it is determined that the passenger side door is closed, the back-drive is performed to be easily closed.

이와 같이 본 발명에 의하면 차량이 좌우의 높이가 서로 다른 도로에 주정차하고 탑승객이 하차하는 경우에 발생되는 차량 횡방향 구배에 따른 도어의 구배 및 하중에 의한 도어개폐의 어려움을 해소할 수 있는 효과가 있다. As described above, according to the present invention, when the vehicle stops on a road having different heights from the left and right, and the passengers get off, it is possible to solve the difficulty of opening and closing the door due to the gradient of the door and the load according to the transverse gradient of the vehicle. have.
