In particular, a photo electric sensor is mounted at the bottom of a car bumper to measure a width between obstacles lying in the direction of travel of the vehicle, and accordingly, whether or not the vehicle passes through It relates to a vehicle front width measuring device that informs the driver.

일반적으로, 자동차가 좁은 골목길을 통과하는 경우에 운전자는 육안으로 장애물과 장애물 사이의 폭을 측정하여 자동차의 통과 가능성을 판단한다. 즉, 제1도에 도시된 것처럼 자동차가 좁은 골목길을 통과하는 경우에 운전자(3)는 전방에 주차되어 있는 자동차(1)와 전신주(2) 사이의 폭(W)을 육안으로 판단하여 자동차의 통과 가능성을 판단한다.In general, when a car passes a narrow alleyway, the driver visually measures the width between the obstacle and the obstacle to determine the possibility of passing of the car. That is, when the car passes through a narrow alley as shown in FIG. 1, the driver 3 visually determines the width W between the car 1 and the telephone pole 2 parked in front of the car. Determine the possibility of passing.

그러나, 대부분의 운전자는 주차된 자동차의 사이드 미러(side mirror)나 범퍼 돌출부 등을 고려하지 않고 자동차의 바디(body)와 장애물 사이의 폭 만을 부정확한 육안으로 측정하여 자동차를 진입시킴에 따라 접촉사고가 발생하여 주차된 자동차와 자신의 자동차에 손상을 입히는 경우가 있었다.However, most drivers do not take into account side mirrors or bumper protrusions of parked cars, and inaccurately measure the width between the body and obstacles of the car with inaccurate visual observation. Occasionally there was a case of damaging parked cars and their cars.

이에, 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 자동차 범퍼의 하단에 광전자 센서(photo electric sensor)를 장착하여 자동차 진행방향에 놓여 있는 장애물 사이의 폭을 측정하고 이를 운전자에게 알려주므로써, 부정확한 운전자의 육안측정으로 인한 무리한 자동차의 진입으로 발생할 수 있는 자동차의 손상을 방지하는 자동차 전방 통과폭 측정장치를 제공하는 것을 그 목적으로 한다.Accordingly, the present invention has been made to solve the above problems, by mounting a photo electric sensor at the bottom of the bumper of the car to measure the width between the obstacles in the direction of travel of the car to inform the driver It is an object of the present invention to provide a vehicle front pass width measurement device that prevents damage to a vehicle that may occur due to excessive entry of the vehicle due to inaccurate driver's visual measurement.

상기와 같은 목적을 달성하기 위하여 본 발명은, 자동차 범퍼의 소정부위에 장착되어 자동차 진행방향에 놓여있는 장애물 사이의 폭을 측정하는 광전자 센서와, 상기 광전자 센서에서 측정된 장애물 사이의 폭과 자동차의 폭을 비교하여 그에따른 제어신호를 출력하는 제어부와, 상기 제어부의 출력신호에 따라 운전자에게 자동차의 통과 가능성 여부를 알려주는 디스플레이부를 구비하는 것을 특징으로 한다.In order to achieve the above object, the present invention, an optoelectronic sensor mounted on a predetermined portion of the vehicle bumper to measure the width between the obstacle lying in the vehicle traveling direction, and the width between the obstacle measured by the photoelectric sensor and the vehicle And a display unit for comparing the width and outputting a control signal according to the width, and a display unit for informing a driver whether or not the vehicle is allowed to pass according to the output signal of the controller.

이하, 본 발명의 바람직한 일실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 발명에 따른 자동차 전방 통과폭 측정장치의 구성 블럭도로, 광전자 센서(photo electric sensor)(10)는 자동차 범퍼 하단부에 장착되어 자동차 전방에 놓여있는 장애물(1,2)과의 거리(L,L')를 측정하고, 또한 장애물 사이의 각도(θ)를 고려하여 장애물 사이의 폭(W)을 측정한다.2 is a block diagram of a vehicle front pass width measuring apparatus according to the present invention, wherein a photo electric sensor 10 is mounted at a lower end of an automobile bumper and is disposed at a distance from an obstacle 1 and 2 placed in front of the vehicle. L, L ') and the width W between the obstacles is measured in consideration of the angle θ between the obstacles.

제어부(20)는 광전자 센서(10)에서 측정된 장애물 사이의 폭(W)을 자신의 자동차의 폭과 비교하여 그에따른 제어신호를 출력하며, 디스플레이부(30)는 제어부(20)의 제어신호에 따라 자동차의 통과 가능성 여부를 운전자에게 알려준다.The controller 20 compares the width W between the obstacles measured by the photoelectric sensor 10 with the width of the vehicle, and outputs a control signal accordingly. The display unit 30 controls the control signal of the controller 20. Inform the driver whether the car is likely to pass.

제3도는 디스플레이부(30)의 일예를 나타낸 것으로, 자동차 계기판(40)의 소정부위에 장착되어 있으며, 장애물 사이의 폭(W)을 나타내는 통과 폭 디스플레이부(31)와 통과 가능성 여부를 나타내는 경고등(32)으로 구성되어 있다.FIG. 3 shows an example of the display unit 30. The display unit 30 is mounted on a predetermined portion of the vehicle instrument panel 40, and has a passage width display unit 31 indicating a width W between obstacles and a warning lamp indicating whether the passage is possible. It consists of 32.
