이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 설명한다. 또한 본 실시예는 본 발명의 권리범위를 한정하는 것은 아니고, 단지 예시로 제시된 것이다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. In addition, this embodiment is not intended to limit the scope of the present invention, but is presented by way of example only.

도1은 본 발명에 따른 와이퍼 시스템의 보호장치에 관한 구성도이다.1 is a block diagram of a protection device for a wiper system according to the present invention.

여기에 도시된 바와 같이 본 발명은 와이퍼의 작동 및 속도를 제어할 수 있는 와이퍼 스위치(10)와, 와이퍼스위치(10)에 의해 간헐적 시간모드 신호가 입력될 경우에 와이퍼 모터(60)의 동작전류에 따라 와이퍼 모터(60)의 기본 동작시간 대비 휴지타임을 증대하여 모터의 과부하 및 발열을 방지하는 간헐적 시간모드 스위치(20)와, 와이퍼 모터(60)와 릴레이(55)의 매개단에 설치되어 실제 와이퍼 모터(60)에 걸리는 부하전류를 감지하여 출력하는 전류감응센서(50)와, 이 때 전류감응센서(50)를 통해 입력된 전류의 정도에 따라 와이퍼 모터(60)의 동작타임을 제어하는 전자제어장치(30)와, 와이퍼 모터(60)의 과부하 상태시 운전자에게 경고할 수 있게 해주는 운전자경고등(40)으로 이루어져 있다.As shown here, the present invention provides a wiper switch 10 capable of controlling the operation and speed of the wiper, and an operating current of the wiper motor 60 when an intermittent time mode signal is input by the wiper switch 10. In accordance with the intermittent time mode switch 20 to prevent overload and heat generation of the motor by increasing the idle time compared to the basic operating time of the wiper motor 60, the wiper motor 60 and the relay 55 is installed at the intermediate stage The current sensing sensor 50 which detects and outputs a load current applied to the wiper motor 60 and controls the operation time of the wiper motor 60 according to the degree of current input through the current sensitive sensor 50. The electronic control device 30 and the driver warning lamp 40 to warn the driver when the wiper motor 60 is overloaded.

여기서 전류감응센서(50)에 의해 와이퍼모터(60)에 흐르는 전류량이 과부하 상태로 입력이 되면 와이퍼 동작속도가 LOW/HIGH 모드일 경우에는 와이퍼모터(60)의 전류를 완전차단하고 INT 모드일 경우에는 와이퍼 구동 시간을 연장 또는 차단한다.In this case, when the amount of current flowing into the wiper motor 60 is input by an overload state by the current sensitive sensor 50, when the wiper operation speed is LOW / HIGH mode, the current of the wiper motor 60 is completely shut off and in the INT mode. The wiper drive time is extended or cut off.

위와 같이 이루어진 본 발명에 따른 와이퍼 시스템의 보호장치를 도 2에 도시된 흐름도를 참조하여 설명하면 다음과 같다.Referring to the flow chart shown in Figure 2 the wiper system according to the present invention made as described above is as follows.

먼저, 사용자가 와이퍼 스위치(10)를 ON시키면(S10), 와이퍼모터(60)가 동작(S20)하게 되는데, 이 때 전류감응센서(50)가 와이퍼모터(60)의 구동전류를 감지해 전자제어장치(30)에 피드백하면(S30), 전자제어장치(30)는 와이퍼모터(60)의 현동작상황을 판단해(S40), 동작전류가 정상인 경우에는 INT 모드 및 LOW 모드시 휴지타임이 정상인지를 판단하고(S50), 정상이면 다시 처음으로 돌아가게 된다. 여기서 와이퍼모터(60)의 동작전류가 정상적이지 않을 경우에는 와이퍼 모터(60)의 동작타임을 지연시키거나 전류를 차단하여 와이퍼 모터(60)의 동작을 일시적으로 멈추게 한다. 또한, 릴레이(55) 전원을 차단(S60)하고, 운전자에게 경보하여 와이퍼의 동작을 운전자 스스로 멈출 수 있게 해준다(S70). 그 다음에 일정시간(본 실시예에서는 30초로 설정)이 지나면 와이퍼모터(60)를 구동시키고 릴레이(55)의 전원을 재공급하여 과부하 여부를 계속 체크 및 검증하게 되는 것이다(S80).First, when the user turns on the wiper switch 10 (S10), the wiper motor 60 is operated (S20), at which time the current sensitive sensor 50 detects the drive current of the wiper motor 60 When feeding back to the control device 30 (S30), the electronic control device 30 determines the current operating status of the wiper motor 60 (S40), the idle time in the INT mode and LOW mode when the operating current is normal It is determined whether it is normal (S50), and if it is normal, it returns to the beginning again. If the operating current of the wiper motor 60 is not normal, the operation time of the wiper motor 60 is delayed or the current is interrupted to temporarily stop the operation of the wiper motor 60. In addition, the relay 55 shuts off the power (S60), and alerts the driver to allow the driver to stop the operation of the wiper himself (S70). Then, after a predetermined time (in this embodiment, set to 30 seconds), the wiper motor 60 is driven and the power supply of the relay 55 is re-supplied to continuously check and verify whether or not an overload occurs (S80).

상기한 바와 같이 본원 발명은 와이퍼모터가 동작시에 와이퍼 모터에 흐르는 전류를 감지하여 피드백함으로써 불필요한 와이퍼의 동작을 차단하고 와이퍼 시스템의 손상을 방지할 수 있도록 할 수 있는 이점이 있다.As described above, the present invention has an advantage that the wiper motor detects and feeds back a current flowing in the wiper motor to block unnecessary wiper operation and prevent damage to the wiper system.
