Description

차량주행중 트렁크오픈 방지회로Trunk open prevention circuit while driving

본 고안은 차량주행중 트렁크오픈 방지회로에 관한 것으로, 좀더 상세하게는 자동차의 주행중에는 운전자가 트렁크스위치를 오조작하여도 트렁크가 오픈되지 않도록 하는 차량주행중 트렁크오픈 방지회로에 관한 것이다.The present invention relates to a trunk open prevention circuit during vehicle driving, and more particularly, to a trunk open prevention circuit during vehicle driving such that the trunk is not opened even if the driver incorrectly operates the trunk switch while driving the vehicle.

통상적으로, 자동차의 후방에는 화물이 적재되는 일정용량의 트렁크룸과, 이 트렁크룸을 외부로부터 차단하는 트렁크도어 등으로 이루어지는 트렁크가 마련되어 있다.Normally, the rear of the vehicle is provided with a trunk compartment having a certain capacity in which cargo is loaded, and a trunk door for blocking the trunk compartment from the outside.

이와 같은 자동차의 트렁크는 운전석에 마련된 트렁크스위치를 조작함으로써 오픈되는데, 이는 도 1을 참조하면, 운전자의 조작으로 상기 트렁크스위치(S1)가 단락되어 배터리전원(B+)을 트렁크솔레노이드(SOL)로 인가함으로써 가능하게 되는 것이다.The trunk of such a vehicle is opened by operating a trunk switch provided in the driver's seat. Referring to FIG. 1, the trunk switch S1 is short-circuited by a driver's operation to apply the battery power B + to the trunk solenoid SOL. It is possible by doing this.

그러나, 간혹은 차량주행시 운전자의 실수로 인하여 상기 트렁크스위치(S1)가 조작되는 경우가 있다. 예를 들면, 타 차량의 임대시나 새로 구입하여 적응되지 못한 상태에서 차량주행중에 조작패널 상의 다른 스위치를 조작하려다가 조작패널을 정확히 확인하지 못한 채로 상기 트렁크스위치(S1)를 조작하여 트렁크를 오픈시킨 채로 차량을 주행하는 경우가 있다.However, sometimes the trunk switch S1 may be manipulated due to a driver's mistake when the vehicle is driven. For example, while operating the other switch on the operation panel while the vehicle is being rented or when a new purchase cannot be adapted, the trunk switch S1 is operated to open the trunk without accurately confirming the operation panel. There may be a case where a vehicle is driven.

이와 같이 작동되어 트렁크가 오픈된 상태이더라도 차량주행 중에는 트렁크를 닫을 수가 없기 때문에 차량을 도로 상에서 정차한 후 트렁크를 닫아야 하므로, 운전자를 불편하게 하고, 더욱이 타차량의 교통흐름에 방해가 되는 동시에 사고를 초래할 우려가 있다는 문제점이 있었다.In this way, even when the trunk is open, the trunk cannot be closed while the vehicle is being driven. Therefore, the vehicle must be closed on the road and the trunk must be closed. This makes the driver uncomfortable and further disrupts the traffic flow of other vehicles. There was a problem that it may cause.

전술한 문제점을 해결하기 위해 안출된 본 고안은 차량주행중에는 상기 트렁크스위치를 조작해도 상기 트렁크솔레노이드가 작동되지 않도록 하기 위해 차량주행을 감지하여 상기 트렁크스위치로 인가되는 배터리전원을 차단하는 차량주행중 트렁크오픈 방지회로를 제공하려는 것이다.The present invention devised to solve the above-mentioned problem is to open the trunk while driving the vehicle to detect the driving of the vehicle so as not to operate the trunk switch even when operating the trunk switch to cut off the battery power applied to the trunk switch To provide a protection circuit.

전술한 목적을 달성하기 위한 본 고안에 따르면, 구동시에 트렁크도어를 오픈하는 트렁크솔레노이드의 전단에 접속되어 운전자의 조작에 따라 상기 트렁크솔레노이드의 구동전류를 스위칭하는 트렁크스위치의 전단에 인가되는 배터리전원을 차단하는 트렁크오픈 방지회로에 있어서, 차량주행상태를 감지하는 전자제어유닛의 출력에 따라 단락되어 연료펌프모터로 배터리전원을 공급하는 절환접점 및 고정접점을 구비하는 연료펌프릴레이에 상기 절환접점과 상기 고정접점의 미단락시에 상기 절환접점과 단락되는 제 2 고정접점을 더 구비시키고, 상기 제 2 고정접점에 상기 트렁크스위치의 전단을 접속시켜서 됨을 특징으로 하는 차량주행중 트렁크오픈 방지회로가 제공된다.According to the present invention for achieving the above object, it is connected to the front end of the trunk solenoid to open the trunk door during the driving, the battery power applied to the front end of the trunk switch for switching the drive current of the trunk solenoid according to the driver's operation In the trunk open prevention circuit for blocking, the switching contact and the switching contact to the fuel pump relay having a switching contact and a fixed contact for supplying battery power to the fuel pump motor is short-circuited according to the output of the electronic control unit for detecting the vehicle driving state When the fixed contact is not short-circuited, a second fixed contact short-circuited with the switching contact is further provided, and the front end of the trunk switch is provided, wherein the front end of the trunk switch is connected to the second fixed contact.

이하, 도면을 참조하여 본 고안의 바람직한 실시예를 더욱 상세히 설명하며, 종래와 동일한 부분에 대해서는 동일한 도면부호를 부여하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings, and like reference numerals will be used to designate like parts.

도 2에 도시된 바와 같이, 운전자의 조작에 따라 스위칭되는 트렁크스위치(S1) 후단에 트렁크도어의 개방을 구동하는 트렁크솔레노이드(SOL)가 접속되어 구성되는 것은 통상적인 트렁크오픈 구동회로이다. 또, 차량주행상태를 감지하여 구동전류를 출력하는 전자제어유닛(ECU)의 후단에 연료펌프릴레이(RY)의 코일을 통해 이그니션전원(IG+)이 인가되도록 구성되고, 상기 연료펌프릴레이(RY)에 상기 코일이 여자됨에 따라 서로 단락되는 절환접점(a) 및 고정접점(b)이 구비되고, 상기 절환접점(a)에는 배터리전원(B+)이 인가되며, 상기 고정접점(b)에는 연료펌프모터(M)가 접속되어 구성되는 것은 통상적인 연료펌프 구동회로이다.As shown in FIG. 2, a trunk solenoid SOL for driving the opening of the trunk door is connected to a rear end of the trunk switch S1 switched according to the driver's operation. In addition, the ignition power source IG + is applied to the rear end of the electronic control unit ECU which detects the vehicle driving state and outputs the driving current through the coil of the fuel pump relay RY, and the fuel pump relay RY A switching contact (a) and a fixed contact (b) are short-circuited with each other as the coil is excited, and a battery power source (B +) is applied to the switching contact (a), and the fuel pump is connected to the fixed contact (b). It is a typical fuel pump drive circuit which the motor M is connected and comprised.

본 고안의 특징은 상기 연료펌프릴레이(RY)에 상기 절환접점(a)과 상기 고정접점(b)의 미단락시에 상기 절환접점(a)과 단락되는 제 2 고정접점(c)을 더 구비시키고, 상기 제 2 고정접점(c)에 상기 트렁크스위치(S1)의 전단을 접속시켜 구성함에 있다.A feature of the present invention is further provided with a second fixed contact (c) which is short-circuited with the switching contact (a) when the switching contact (a) and the fixed contact (b) are not short-circuited in the fuel pump relay (RY). The front end of the trunk switch (S1) is connected to the second fixed contact (c).

이와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

차량주행시에는 전자제어유닛(ECU)의 출력에 따라 연료펌프릴레이(RY)의 코일이 여자되어 절환접점을 고정접점(b)으로 단락하게 됨에 따라 제 2 고정접점(c)은 절환접점(a)으로부터 탈락하게 되므로, 상기 제 2 고정접점(c)의 후단에 접속된 트렁크스위치(S1)로 공급되는 배터리전원(B+)은 차단되고, 이에 따라 트렁크스위치(S1)를 온해도 트렁크솔레노이드(SOL)는 구동하지 않게 된다. 따라서, 운전자가 운전석의 조작패널에 마련된 상기의 트렁크스위치(S1)를 실수로 조작하더라도 트렁크가 오픈되지 않게 된다.When driving the vehicle, the coil of the fuel pump relay RY is excited according to the output of the electronic control unit ECU, and the switching contact is short-circuited to the fixed contact b so that the second fixed contact c becomes the switching contact a. Since it is eliminated from the, the battery power (B +) supplied to the trunk switch (S1) connected to the rear end of the second fixed contact (c) is cut off, thereby turning on the trunk switch (S1) trunk solenoid (SOL) Will not run. Therefore, even if the driver accidentally operates the trunk switch S1 provided on the operation panel of the driver's seat, the trunk is not opened.

한편, 차량의 정차중에는 전자제어유닛(ECU)의 출력이 차단되어 연료펌프릴레이(RY)의 코일이 비여자됨에 따라 절환접점(a)이 제 2 고정접점(c)으로 절환접속되므로, 상기 제 2 고정접점(c)의 후단에 접속된 트렁크스위치(S1)가 온상태로 되면 트렁크솔레노이드(SOL)가 구동하게 되므로 운전자의 트렁크스위치(S1) 조작에 따라 트렁크를 오픈시킬 수 있게 된다.On the other hand, since the output of the electronic control unit ECU is interrupted and the coil of the fuel pump relay RY is de-energized while the vehicle is stopped, the switching contact a is switched to the second fixed contact c. 2 When the trunk switch S1 connected to the rear end of the fixed contact c is turned on, the trunk solenoid SOL is driven so that the trunk can be opened according to the driver's operation of the trunk switch S1.

이상에서 설명한 바와 같이 본 고안은 운전자가 실수로 트렁크스위치를 조작하더라도 차량주행중에는 트렁크가 오픈되지 않도록 하는 차량주행중 트렁크오픈 방지회로를 제공함으로써 종래의 트렁크열림으로 인한 운전자의 불편과 타차량에 대한 교통방해 및 사고의 우려를 해소할 뿐 아니라, 본 고안에 의한 차량주행중 트렁크오픈 방지회로에 통상적으로 사용되는 연료펌프 구동회로의 일부를 활용함으로써 코스트를 절감하여 실용화할 수 있는 효과가 있다.As described above, the present invention provides a trunk open prevention circuit while driving so that the trunk is not opened while the vehicle is driven even if the driver accidentally operates the trunk switch, thereby preventing the driver's inconvenience caused by the conventional trunk opening and traffic to other vehicles. In addition to solving the concerns of interference and accidents, by utilizing a part of the fuel pump driving circuit commonly used in the trunk open prevention circuit while driving the vehicle according to the present invention there is an effect that can be practical to reduce the cost.
