Description

차량 후진시 후방 거리 측정 장치Rear distance measuring device when reversing the vehicle

본 고안은 차량에 있어서, 후진시 차량과 후방 물체와의 거리를 확인할 수 있도록 하여 안전운행이 가능하도록 한 차량 후진시 후방 거리 측정 장치에 관한 것이다.The present invention relates to a rear distance measuring apparatus for reversing a vehicle to enable safe driving by checking a distance between a vehicle and a rear object when reversing.

일반적으로 차량 후진은 후진 주차를 할 경우 또는 후진 주행을 할 경우에 이루어지는 것이다.In general, vehicle reversal occurs when reversing parking or reverse driving.

이와 같은 후진 동작은 우선, 기어변속을 후진변속단으로 해두고 액셀을 천천히 밟아야만 이루어진다. 이때, 운전자는 백미러만으로는 후방을 제대로 확인할 수 없으므로 조수석의 헤드 레스트에 오른쪽 팔을 걸친채 고개를 뒤로 돌려 후방 유리를 통해 뒤를 확인해 가면서 이동해야 한다.This reverse operation is first achieved by slowly stepping on the accelerator with the gear shift in the reverse shift stage. At this time, the driver cannot see the rear properly by the rearview mirror alone, so he must move his head backwards while keeping his right arm on the head restraint of the passenger seat and look back through the rear glass.

그런데, 상기 후진 동작이 후진 주차시 이루어질 경우에는 후방 유리를 통해서도 운전자가 확인할 수 없는 물체가 간혹 있게 된다.However, when the reverse operation is performed during the reverse parking, there are sometimes objects that the driver cannot check even through the rear glass.

즉, 주차 경계를 나타내는 경계석이 낮게 설치되어 있을 경우가 그러한 경우이다.That is, the case where the boundary seat which shows a parking boundary is set low is such a case.

이에 따라, 차량 후진의 경우에는 운전 초보자나 숙련자에 관계없이 차체 손상, 이에 더해 인명 피해까지 발생하게 된다.Accordingly, in the case of reversing the vehicle, regardless of the novice or experienced driver, damage to the vehicle body, in addition to personal injury occurs.

본 고안은 상기와 같은 문제점을 해결하기 위해 고안된 것으로, 차량 후미에 후방 물체를 감지하는 센서를 구비하고, 이 센서를 통해 물체와 차량간의 거리를 측정하도록 하는 장치를 제공하여 안전한 차량 후진이 이루어질 수 있도록 함을 목적으로 한다.The present invention is designed to solve the above problems, and has a sensor for detecting a rear object at the rear of the vehicle, and provides a device for measuring the distance between the object and the vehicle through the sensor to ensure safe vehicle reverse For the purpose of

상기 목적을 달성하기 위한 본 고안 차량 후진시 후방 거리 측정 장치는, 기어 변속이 후진변속단으로 되면 온상태가 되어 후진등을 점등시키는 후진등 스위치를 구비하고 있는 차량에 있어서, 상기 후진등 스위치가 온상태가 되면 후방으로 신호를 보내고 반사되어 오는 신호가 있으면 후방에 물체가 있음을 확인하는 후방 물체 감지 센서와; 상기 후방 물체 감지 센서에서 출력된 신호가 다시 수신되기까지의 시간을 측정하여 후방 물체와 차량간의 거리를 산출하고 이에 따른 제어동작을 실시하는 ECM과; 상기 ECM의 제어를 받아 차량과 후방물체와의 거리를 숫자로 표시하여 운전자에게 알리는 디스플레이를 포함하는 것을 특징으로 한다.The rear distance measuring device for reversing the vehicle according to the present invention for achieving the above object has a reverse light switch for turning on the reverse light when the gear shift is in the reverse shift stage, the reverse light switch being A rear object detection sensor which sends a signal to the rear when the signal is turned on and checks that there is an object in the rear when a signal is reflected; An ECM which measures a time until the signal output from the rear object detection sensor is received again, calculates a distance between the rear object and the vehicle, and performs a control operation according to the distance; Under the control of the ECM characterized in that it comprises a display for notifying the driver by displaying the distance between the vehicle and the rear object by a number.

이하, 본 고안의 일실시예를 첨부 도면을 참조로 하여 좀 더 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

제1도는 본 고안 차량 후진시 후방 거리 측정 장치의 구성도로서, 그 구성은 후진등 스위치(1)와, 후진등(2)과, 후방 물체 감지 센서(10)와, ECM(20)과, 디스플레이(30)를 포함한다.1 is a configuration diagram of a rear distance measuring apparatus for reversing the vehicle according to the present invention, the configuration of which is a reversing light switch 1, a reversing light 2, a rear object detecting sensor 10, an ECM 20, And a display 30.

상기 후진등 스위치(1)는 기어 변속이 후진변속단, 즉 'R'위치에 있으면 온상태가 되는 스위치로, 변속 레버의 위치가 'R'의 위치에 오면 스위치 접점이 연결되어 후진등(2)이 점등된다.The reverse light switch 1 is a switch in which the gear shift is turned on when the gear shift is in the reverse shift stage, that is, the 'R' position. When the shift lever is in the 'R' position, the switch contact is connected to the reverse light (2). ) Lights up.

상기 후방 물체 감지 센서(10)는 상기 후진등 스위치(1)의 온상태로부터 인가되는 전원으로 동작하는 것으로, 후방으로 신호를 보내어 다시 반사되어 오는 신호를 수신한다. 이와 같은 동작을 위해 상기 센서(10)는 차량 후미에 수개 장착된다. 그리고, 상기 센서(10)의 일례로는 초음파 센서, 레이저 센서 또는 적외선 센서등을 들 수 있다.The rear object detecting sensor 10 operates by a power source applied from an on state of the reverse light switch 1 and sends a signal to the rear to receive a signal reflected back. For this operation, several sensors 10 are mounted on the rear of the vehicle. In addition, an example of the sensor 10 may be an ultrasonic sensor, a laser sensor, an infrared sensor, or the like.

상기 ECM(20)은 상기 후방 물체 감지 센서(10)에서 송출되는 신호의 송출시각과 이에 반사되어 수신되는 신호의 수신시각을 측정하여 차량과 후방 물체 사이의 거리를 측정한다. 즉, 상기 후방 물체 감지 센서(10)가 초음파 센서이면 신호의 속도를 소리 속도로 하여 거리를 구하고, 레이저 센서이면 신호의 속도를 빛의 속도로 하여 거리를 구한다.The ECM 20 measures a distance between a vehicle and a rear object by measuring a transmission time of a signal transmitted from the rear object detection sensor 10 and a reception time of a signal reflected and received by the rear object detection sensor 10. That is, if the rear object sensor 10 is an ultrasonic sensor, the distance is obtained by using the speed of the signal as the sound speed, and the distance is obtained by using the speed of the signal as the speed of the light when the laser sensor is used.

상기 디스플레이(30)는 상기 ECM(20)의 제어를 받아 차량과 후방 물체 사이의 거리를 운전자가 알아보기 쉽게 숫자로 표시한다.Under the control of the ECM 20, the display 30 displays the distance between the vehicle and the rear object by numbers so as to be easily understood by the driver.

상기와 같은 구성으로 이루어진 본 고안의 동작은 다음과 같다.The operation of the present invention made of the above configuration is as follows.

차량 주행중에는 후진등 스위치(1)가 오프상태에 있으므로 후방 물체 감지에 따른 동작은 수행되지 않는다.Since the reverse light switch 1 is in the off state while driving the vehicle, the operation according to the rear object detection is not performed.

그런데, 이때 기어 변속을 후진변속단으로 하게 되면 후진등 스위치(1)가 접점되어 후진등(2)이 점등되면서 후방 물체 감지 센서(10)에서 물체 감지를 위한 신호가 소정 시간 간격으로 발생하게 된다.However, in this case, when the gear shift is made into the reverse shift stage, the reverse light switch 1 is contacted and the reverse light 2 is turned on, so that the signal for object detection is generated at a predetermined time interval in the rear object detection sensor 10. .

여기서, 수신되는 신호가 없으면 ECM(20)에서는 후방에 물체가 없는 것으로 확인하고 디스플레이(30) 상에 아무런 숫자도 표시되지 않도록 한다.Here, if there is no signal received, the ECM 20 confirms that there is no object behind and does not display any number on the display 30.

반면, 후방 물체 감지 센서(10)에서 송출된 신호에 대해 수신신호가 있음이 확인되면, ECM(20)에서는 그 시간 간격을 측정하여 후방 물체와 차량간의 거리를 산출하게 된다. 이와 같은 거리 산출 동작은 기어 변속이 후진에서 다른 기어 변속으로 넘어갈 때까지 계속된다.On the other hand, when it is confirmed that there is a reception signal for the signal transmitted from the rear object sensor 10, the ECM 20 calculates the distance between the rear object and the vehicle by measuring the time interval. This distance calculation operation continues until the gear shift is shifted from reverse to another gear shift.

이와 같이 ECM(20)에서 산출된 거리는 디지탈 신호로 변환되어 디스플레이(30) 상에 숫자로 표시된다.In this way, the distance calculated by the ECM 20 is converted into a digital signal and displayed on the display 30 as a number.

이에 운전자는 후방 물체와의 거리를 쉽게 확인하여 적당한 위치에서 정지할 수 있게 된다. 또한, 갑작스럽게 차량 후미쪽을 가로질러 지나는 사람이나 차량 또는 물건등에 의해서도 거리 확인이 신속하게 이루어져 안전한 후진이 이루어지게 된다.Accordingly, the driver can easily check the distance to the rear object and stop at an appropriate position. In addition, the distance is quickly confirmed by a person, a vehicle, or an object that suddenly crosses the rear of the vehicle, so that a safe reverse is achieved.

이상에서 살펴본 바와 같이 본 고안에 따르면, 차량 후진시 운전자가 확인하지 못하는 장애물과의 거리를 쉽게 확인할 수 있게 되어 후진으로 인한 차체 손상 또는 인명 피해가 방지된다.As described above, according to the present invention, it is possible to easily check the distance to the obstacle that the driver cannot check when the vehicle is reversed, thereby preventing the body damage or the human injury caused by the reverse.
