본 발명은 AT(Automatic Transmission) 차량 경고장치에 관한 것으로, 보다 상세하게는 사이드 브레이크(side brake)를 걸어두지 않은 상태에서 기어가 중립(Neutral)모드에 위치할 때, 키박스에 시동키를 꽂고 이그니션 온(Ignition ON)하여 바로 주행(DRIVE)모드로 전환하면, 알람이 작동되도록 한 AT차량의 중립주차시 주행모드변경 경고장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an AT (Automatic Transmission) vehicle warning device, and more particularly, to an AT (Automatic Transmission) vehicle warning device in which, when a gear is in Neutral mode without a side brake, The present invention relates to a driving mode change warning device for an AT vehicle in which the alarm is activated when the ignition is turned ON and the vehicle is immediately switched to the DRIVE mode.

일반적으로 AT차량은 주/정차 후 시동을 걸 경우에, 변속모드가 파크(PARK)모드나 중립모드에 위치되었을 때만 시동이 걸리도록 되어 있다.Generally, when the AT vehicle is started after the main / stop, the AT vehicle is started only when the shift mode is set in the PARK mode or the neutral mode.

운전자가 통상 경사도가 없는 아파트 주차나, 차량 주차가 빈번한 주차장 등에서 차량을 주차시킬 경우에는 사이드 브레이크를 걸어두지 않는 것이 차량예절로 일반화되어 가는 추세이다.When a driver parks a car in an apartment parking without regular inclination, or in a parking lot where vehicle parking is frequent, it is becoming common practice to not put side brakes on the car.

이와 같이 운전자가 기어가 중립인 상태에서 키박스에 시동키를 꽂고 이그니션 온(Ignition ON)하게 되면 시동이 걸리게 되는데 이때 운전자의 실수로 인해 브레이크를 밟지 않고 기어를 주행모드로 변속하게 될 경우, 차량이 전방으로 급진행하게 된다.When the ignition key is inserted into the key box and the ignition is turned on, the engine is started. In this case, when the driver shifts the gear to the running mode without stepping on the brake due to the mistake of the driver, As shown in FIG.

이때 만약 전방에 차량이 위치해 있거나 장애물이 있을 경우에는 추돌위험이 내재하게 되는 문제점이 있다.At this time, if the vehicle is located ahead or there is an obstacle, the risk of a collision is inherent.

본 발명은 상기 종래의 문제점을 해결하기 위하여 안출된 것으로, 사이드 브레이크를 걸어두지 않은 상태에서 기어가 중립모드에 위치할 때, 키박스에 시동키를 꽂고 이그니션 온(Ignition ON)하여 바로 주행(DRIVE)모드로 전환하게 되면, 알람이 작동되도록 함으로써, 전방장애물 또는 전방차량과의 접촉사고 위험을 미연에 방지할 수 있도록 하는데 그 목적이 있다.DISCLOSURE OF THE INVENTION The present invention has been conceived to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a hybrid vehicle in which when a gear is positioned in a neutral mode without a side brake applied, a starter key is inserted into a key box, ) Mode, the alarm is activated so that the risk of accidental contact with the front obstacle or the front vehicle can be prevented.

상기 목적을 달성하기 위한 수단으로, 셀렉터 포지션 스위치의 각 모드(P,R,N,D,2,1)가 트랜스미션 제어 모듈의 각 입력단자에 연결되고, 풋 브레이크 스위치 및 차량 속도 센서가 구비된 차량에 있어서, 일측이 배터리 전원에 연결된 상기 풋 브레이크 스위치의 타측에 연결된 제1 인버터와; 상기 차량 속도 센서의 출력측에 연결된 제2 인버터와; 상기 제1 및 제2 인버터의 출력측과, 상기 셀렉터 포지션 스위치의 중립모드(N)의 출력측 및 배터리 전원이 각 입력단자에 연결된 앤드게이트와; 상기 앤드게이트의 출력측이 일측접지된 코일 타측에 연결되고, 가동접점이 배터리 전원에 연결된 릴레이와; 상기 릴레이의 고정접점이 연결된 타이머와; 상기 타이머의 출력측이 연결된 알람발생부를 포함함으로써 달성된다.In order to achieve the above-mentioned object, there is provided a vehicle speed control system in which each mode (P, R, N, D, 2,1) of a selector position switch is connected to each input terminal of a transmission control module, 1. A vehicle comprising: a first inverter connected to the other side of the foot brake switch, one side of which is connected to battery power; A second inverter connected to an output side of the vehicle speed sensor; An AND gate connected to an output side of the first and second inverters, an output side of a neutral mode (N) of the selector position switch, and a battery power source to each input terminal; A relay connected to an output side of the AND gate and to the other side of the grounded coil, the movable contact connected to a battery power source; A timer connected to a fixed contact of the relay; And an alarm generating unit to which the output side of the timer is connected.

이하에서 본 발명의 바람직한 실시예를 첨부된 도면에 의거 상세히 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부된 도면은 본 발명에 의한 AT차량의 중립주차시 주행모드변경 경고장치의 회로구성도를 도시한 것으로, 셀렉터 포지션 스위치(SPS)의 각 모드(P,R,N,D,2,1)가 트랜스미션 제어 모듈(TCM)의 각 입력단자에 연결되고, 풋 브레이크 스위치(SW) 및 차량 속도 센서(VSS)가 구비된 차량에 있어서, 일측이 배터리전원(B+)에 연결된 상기 풋 브레이크 스위치(SW)의 타측에 제1 인버터(IVT1)가 연결되고, 상기 차량 속도 센서(VSS)의 출력측에 제2 인버터(IVT2)가 연결된다.(P, R, N, D, 2, 1) of the selector position switch (SPS) Is connected to each input terminal of a transmission control module (TCM) and is provided with a foot brake switch (SW) and a vehicle speed sensor (VSS), the foot brake switch The first inverter IVT1 is connected to the other side of the vehicle speed sensor VSS and the second inverter IVT2 is connected to the output side of the vehicle speed sensor VSS.

또한 상기 제1 및 제2 인버터(IVT1,IVT2)의 출력측과, 상기 셀렉터 포지션 스위치(SPS)의 중립모드(N)의 출력측 및 배터리 전원(B+)이 앤드케이트(AND)의 각 입력단자(1∼4)에 연결된다.The output side of the first and second inverters IVT1 and IVT2 and the output side of the neutral mode N of the selector position switch SPS and the battery power B + 4).

그리고 상기 앤드게이트(AND)의 출력측이 일측접지된 릴레이(RY)의 코일(L) 타측에 연결되고, 릴레이(RY)의 가동접점(a)이 배터리 전원(B+)에 연결된다.The output side of the AND gate is connected to the other side of the coil L of the grounded relay RY and the movable contact a of the relay RY is connected to the battery power source B +.

또한 상기 릴레이(RY)의 고정접점(b)이 타이머(TM)에 연결되고, 이 타이머(TM)의 출력측이 알람발생부(AL)에 연결되도록 구성된다.The fixed contact b of the relay RY is connected to the timer TM and the output side of the timer TM is connected to the alarm generator AL.

이와 같이 구성된 본 발명은 셀렉터 포지션 스위치(SPS)가 중립모드(N)에 위치한 경우에 풋 브레이크 스위치(SW)가 오프된 상태(즉, 운전자가 풋 브레이크 패달을 밟지 않은 상태)로 미도시된 키박스에 시동키를 꽂고 이그니션 온(Ignition ON)하게 되면, 앤드게이트(AND)의 각 입력단자(1∼3)에 각각 하이상태의 신호가 출력된다.The present invention having the above-described structure is configured such that when the selector position switch SPS is located in the neutral mode N, the foot brake switch SW is turned off (i.e., the driver does not press the foot brake pedal) When the starter key is inserted into the box and the ignition is turned on, a high-level signal is output to each of the input terminals 1 to 3 of the AND gate.

또한 차량이 정지상태이기 때문에 차량 속도 센서(VSS)의 출력측을 통해 로우상태의 신호가 출력되어, 제2 인버터(IVT2)를 거쳐 신호반전되어 하이신호가 상기 앤드게이트(AND)의 입력단자(4)에 입력된다.Also, since the vehicle is in a stopped state, a signal in the low state is outputted through the output side of the vehicle speed sensor VSS, and the signal is inverted through the second inverter IVT2 so that a high signal is inputted to the input terminal 4 .

이와 같이 상기 앤드게이트(AND)의 각 입력단자(1∼4)로 하이신호가 입력되면 앤드게이트의 특성에 의해 출력측을 통해 하이신호를 출력하게 된다.Thus, when a high signal is input to each of the input terminals 1 to 4 of the AND gate, a high signal is output through the output side according to the characteristics of the AND gate.

출력된 하이상태의 신호는 릴레이(RY)의 코일(L)에 인가되어, 이 코일(L)을 여자시키게 되고, 이에 의해 가동접점(a)이 고정접점(b)에 붙게 되어 타이머(TM)에 배터리전원(B+)이 인가된다.The outputted high state signal is applied to the coil L of the relay RY to energize the coil L so that the movable contact a is stuck to the fixed contact b and the timer TM, The battery power source B + is applied.

이와 같이 되면 타이머가 작동하여 소정시간동안 시간을 계수하게 되고, 계수되는 시간동안 알람발생부(AL)로 전원이 인가되어 알람이 작동하게 된다.In this case, the timer is activated to count the time for a predetermined time, and the alarm is generated by applying power to the alarm generator AL for the counted time.

이와 같이 알람이 발생되면, 운전자는 변속기어의 위치가 중립모드이고 또한 풋 브레이크 패달을 밟지 않은 상태로 인식하여 전방에 위치한 차량 또는 전방 장애물과의 추돌가능성에 대한 경각심을 갖게 된다.When an alarm is generated, the driver recognizes that the position of the transmission is in the neutral mode and the foot brake pedal is not depressed, so that the driver is aware of the possibility of a collision with the preceding vehicle or the front obstacle.

운전자가 상기 알람을 통해 풋 브레이크 패달을 밟으면, 제1 인버터(IVT1)의 출력측을 통해 로우신호가 출력되고, 이에 의해 앤드게이트(AND)의 출력측으로 로우신호가 출력되어 릴레이(RY)의 작동을 오프시켜 알람발생부(AL)로 인가되는 배터리 전원(B+)을 차단하여 알람작동을 멈추게 된다.When the driver depresses the foot brake pedal through the alarm, a low signal is output through the output side of the first inverter IVT1, thereby outputting a low signal to the output side of the AND gate AND, thereby operating the relay RY Off to shut off the battery power (B +) applied to the alarm generator (AL) and stop the alarm operation.

상술한 바와 같이 본 발명은 사이드 브레이크(일명 핸드 브레이크)를 걸어두지 않은 상태에서 기어가 중립모드에 위치할 때, 키박스에 시동키를 꽂고 이그니션 온하여 바로 주행모드로 전환하면, 알람이 작동되도록 함으로써, 전방장애물 또는 전방차량과의 접촉사고 위험을 미연에 방지할 수 있게 하는 효과가 있다.As described above, according to the present invention, when the gear is in the neutral mode without engaging the side brake (a so-called hand brake), when the ignition key is inserted into the key box and the ignition is turned on, There is an effect that it is possible to prevent a risk of a frontal obstacle or a contact accident with the preceding vehicle in advance.
