Description

자동차의 출발안전장치{a start safety device for a vehicle}Start safety device for a vehicle

본 발명은 자동차의 출발안전장치에 관한 것으로, 특히 출발시 운전자가 세심한 주의를 기울이지 않아도 안전사고가 발생하지 않도록 된 자동차의 출발안전장치에 관한 것이다.The present invention relates to a starting safety device of a vehicle, and more particularly to a starting safety device of a vehicle such that a safety accident does not occur even if the driver does not pay close attention at the start.

일반적으로 주차 및 정차되어 있던 자동차를 출발시키기 위해서는 주차브레이크를 해제하고, 시동키이를 돌려 배터리의 전원으로 기동모터를 가동시켜 엔진을 회전시키며, 변속레버를 조작하여 중립에서 1단(후진일 경우는 R단)으로 변속한뒤, 가속페달을 밟아 주행을 시작하게 된다.Generally, to start a car parked and stopped, release the parking brake, turn the ignition key to operate the starter motor with the power of the battery, and rotate the engine. After shifting to the R stage, the accelerator pedal is pressed to start driving.

그러나, 상기와 같은 동작은 정지되어 있던 자동차를 출발시킬 때마다 반복되는 동작이므로 대부분의 운전자들은 출발시의 조작을 거의 습관적으로 행하게 된다.However, since the above operation is repeated every time the vehicle which has been stopped is started, most drivers almost habitually perform the operation at the start.

따라서, 출발시에 운전자는 주변상황에 그리 세심한 주의를 기울이지 않는 경우가 대부분이며, 더욱이 출발시 운전자의 심리상태가 안정적이지 않은 경우라면(조급함, 주의력 산만 등) 이러한 상황은 더욱 심화된다.Therefore, the driver often does not pay close attention to the surrounding situation at the time of departure, and this situation is further exacerbated if the driver's psychological state is not stable at the time of departure (hurry, distraction, etc.).

따라서, 주차브레이크를 해제하지 않은 상태에서 출발을 하려고 해 자동차가 출발하지 않는 경우도 발생하고, 주위의 장애물들을 정확히 파악하지 못하여 차량이 장애물에 충돌하는 사고도 발생하며, 또한 신호대기후 출발했던 앞차량이 급정지했을 경우 그대로 주행을 계속하여 앞차에 충돌하는 등 여러 가지 안전사고가 발생하는 문제점이 있었다.As a result, the car does not start when the vehicle is about to start without releasing the parking brake, and when the vehicle does not accurately grasp the obstacles around it, an accident occurs when the vehicle collides with the obstacle. When this sudden stop, there was a problem that a number of safety accidents occur such as to continue driving and crash into the front car.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로, 출발시 주차브레이크의 해제여부와 차량의 전후에 위치한 근접 장애물의 유무를 운전자가 확실히 인지하도록 해 주고, 또한 주차브레이크가 걸려 있거나 장애물이 있을때는 엔진으로의 연료분사량을 아이들상태로 유지하여 가속을 억제함으로써 안전한 출발을 할 수 있도록 된 자동차의 출발안전장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, to ensure that the driver is aware of the release of the parking brake at the time of departure and the presence of proximity obstacles located in front and rear of the vehicle, and the parking brake is hung or obstacles The purpose of the present invention is to provide a starting safety device for a vehicle that enables a safe start by keeping the fuel injection amount to the engine in an idle state to suppress acceleration.

이하, 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

도 1은 본 발명에 따른 자동차의 출발안전장치의 개략 구성도로서, 본 발명은 기어의 위치를 감지하여 자동차가 출발하기 위해 1단기어를 걸었는지를 감지하는 기어위치센서(1)와, 주차브레이크가 걸려 있는지를 감지하는 주차브레이크센서(2)와, 차량의 전후단에 장착되어 근접거리 내에 장애물이 있는 지의 여부를 감지하는 장애물감지센서(3)와, 운전자가 악셀페달을 조작중인지 아닌지를 감지하는 악셀페달위치센서(4)가 전자제어장치(5)에 연결되고, 이 전자제어장치(5)에는 연료펌프, 분사노즐등의 연료량을 제어할 수 있는 기존의 연료분사량제어장치(6)와, 차내에 설치된 스피커나 점멸램프등으로 이루어진 경보장치(7)가 연결된 구조로 되어 있다.1 is a schematic configuration diagram of a start safety device of a vehicle according to the present invention, the present invention detects the position of the gear gear position sensor (1) for detecting whether the car has walked the first gear to start, and parking Parking brake sensor (2) for detecting whether the brake is applied, obstacle sensor (3) mounted on the front and rear of the vehicle to detect whether there is an obstacle in close proximity, and whether the driver is operating the accelerator pedal Axel pedal position sensor 4 for sensing is connected to an electronic controller 5, which has a conventional fuel injection amount control apparatus 6 capable of controlling the amount of fuel such as a fuel pump and injection nozzle. And an alarm device 7 made of a speaker or a flashing lamp installed in the vehicle.

여기서, 상기 전자제어장치(5)는 4개의 센서로부터 각각의 감지결과를 입력받게 되는바, 즉 기어위치센서(1)에서는 기어가 1단 또는 후진의 경우 R단으로 변속되었을 때 감지신호가 입력되고, 주차브레이크위치센서(2)에서는 주차브레이크가 걸려 있는 상태에서 감지신호가 입력되며, 장애물감지센서(3)에서는 차량의 전후방에 장애물이 미리 설정해둔 거리(약 3∼4m)내에 있을 경우에 감지신호가 입력되며, 악셀페달위치센서(4)에서는 운전자가 출발가속을 위해 악셀페달을 밟을 때 감지신호가 입력되도록 되어 있다.Here, the electronic control device 5 receives the respective sensing results from the four sensors, that is, the gear position sensor 1 in the gear position sensor 1 when the gear is shifted to the R stage in the case of reversing the input signal In the parking brake position sensor 2, a detection signal is input while the parking brake is applied, and in the obstacle detection sensor 3, when the obstacle is within a predetermined distance (about 3 to 4 m) in front and rear of the vehicle. A detection signal is input, and the axel pedal position sensor 4 is configured to input a detection signal when the driver presses the axel pedal for starting acceleration.

또한, 상기 전자제어장치(5)는 각 센서로부터 입력된 감지신호에 따라 연료분사량제어장치(6)나 경보장치(7)를 작동시키도록 프로그램되어 있는데, 기어위치센서(1)로부터 신호가 입력되면 운전자가 출발조작을 하는 것으로 인지하고 이 상태에서 주차브레이크위치센서(2)로부터 주차브레이크가 걸려 있다는 신호가 입력되면 경보장치(7)를 작동시켜 운전자에게 이를 알려 주차브레이크를 해지토록 한다. 장애물감지센서(3)로부터 차량 주변에 장애물이 있다는 신호가 입력되면 상기 경보장치(7)를 작동시켜 운전자에게 출발을 보류하고 상황을 정확히 인식하도록 하며, 이러한 상태에서도 운전자가 악셀페달을 조작하면 악셀페달위치센서(4)에서 신호가 입력되어 연료분사량제어장치(6)를 작동시켜 엔진으로의 연료분사량을 아이들 상태로 유지케 함으로써 차량이 급가속되지 않도록 한다.In addition, the electronic control device 5 is programmed to operate the fuel injection amount control device 6 or the alarm device 7 according to the detection signal input from each sensor, and a signal is input from the gear position sensor 1. If the driver recognizes that the starting operation and the signal from the parking brake position sensor (2) in this state that the parking brake is applied to operate the alarm device (7) to inform the driver to release the parking brake. When a signal indicating that there is an obstacle around the vehicle is input from the obstacle detecting sensor 3, the alarm device 7 is operated to suspend the driver and recognize the situation accurately. In this state, when the driver operates the accelerator pedal, the accelerator A signal is input from the pedal position sensor 4 to operate the fuel injection amount control device 6 to maintain the fuel injection amount to the engine in an idle state so that the vehicle is not accelerated.

이하, 본 발명의 작동흐름도인 도 2를 참조하여 본 발명의 작동순서를 설명하도록 한다.Hereinafter, the operating sequence of the present invention will be described with reference to FIG. 2, which is a flowchart of the present invention.

본 발명은 운전자가 시동키이를 조작하여 차량이 가조작상태가 됨과 동시에 가동되기 시작하는데, 우선 기어위치센서(1)가 기어위치를 검출하여 기어가 R단이나 1단으로 변속되어 있을 경우 주차브레이크위치센서(2)가 주차브레이크상태를 검출하며, 이 검출상태가 on이라면 상기 경보장치(7)를 작동시키고, 주차브레이크가 off상태라면 장애물감지센서(3)가 장애물의 존재여부를 감지하여 감지된 장애물과의 거리(mf: 전방근접장애물까지의 거리, mr: 후방근접장애물까지의 거리)를 기설정된 기준거리(M : 전술한 바와 같이 대략 3∼4m 정도면 충분하다.)와 비교하여 장애물이 기준거리 이내에 있으면 경보장치(6)를 작동시킴과 동시에 악셀페달위치센서(4)가 악셀페달의 조작상태를 검출한다. 검출된 악셀페달조작상태가 on이라면 전자제어장치(5)는 상기 연료분사량제어장치(6)를 제어하여 연료분사량을 아이들상태로 고정하여 차량이 더 이상 급가속되지 않도록 하고, 악셀페달이 조작되지 않은 상태이면 루프의 처음으로 돌아가서 상기 순서가 반복된다.According to the present invention, when the driver operates the start key and the vehicle is temporarily operated, the vehicle starts to operate. First, when the gear position sensor 1 detects the gear position and the gear is shifted to the R stage or the first stage, the parking brake is applied. The position sensor 2 detects the parking brake state. If the detection state is on, the alarm device 7 is activated. If the parking brake is off, the obstacle sensor 3 detects the presence of an obstacle. Comparing the distance to the obstacle (m f : distance to the front proximity obstacle, m r : distance to the rear proximity obstacle) from the preset reference distance (M: about 3 to 4 m is sufficient as described above). When the obstacle is within the reference distance, the alarm device 6 is activated and the accelerator pedal position sensor 4 detects the operation state of the accelerator pedal. If the detected accelerator pedal operation state is on, the electronic controller 5 controls the fuel injection amount control device 6 to fix the fuel injection amount to an idle state so that the vehicle is no longer accelerated and the axel pedal is not operated. If not, return to the beginning of the loop and repeat the above procedure.

따라서, 운전자가 차량을 출발시키려고 할 때 주차브레이크가 채워져 있으면 경보장치가 작동되어 운전자가 이를 알 수 있으므로 주차브레이크를 곧 해제하여 차량을 출발시킬 수 있으며, 주변에 장애물이 있음에도 불구하고 운전자가 차량을 출발시키려고 할 때 경보장치가 작동되어 운전자가 이를 정확히 알게 됨은 물론, 이 상태에서 악셀페달을 밟아도 연료분사량이 아이들상태로 고정되어 급가속되지 않으므로 차량이 장애물(또는 사람)에 충돌하지 않게 된다.Therefore, if the parking brake is filled when the driver tries to start the vehicle, the alarm is activated so that the driver can know that the parking brake can be released soon and the vehicle can be started. When the driver attempts to start, the alarm is activated so that the driver knows exactly, and even if the accelerator pedal is pressed in this state, the fuel injection amount is fixed to the idle state so that the vehicle does not collide with an obstacle (or a person).

이상 설명한 바와 같이 본 발명에 따르면, 운전자가 차량을 출발시킬 때 차량과 차량 주변의 상황을 정확히 인지할 수 있게 됨과 더불어, 부적절한 출발상황에서는 차량의 급가속이 억제되므로 차량을 원활히 출발시킬 수 있고, 출발시의 안전사고 발생을 방지할 수 있게 되는 효과가 있다.As described above, according to the present invention, when the driver starts the vehicle, the driver can accurately recognize the situation of the vehicle and the surroundings of the vehicle, and the vehicle can smoothly start because the rapid acceleration of the vehicle is suppressed in an inappropriate starting situation. There is an effect that can prevent the occurrence of a safety accident at departure.
