Description

자동차용 와이퍼 자동 제어 시스템{Automatic control system of wiper for automobile}Automatic control system of wiper for automobile}

본 발명은 자동차용 와이퍼 자동 제어 시스템에 관한 것으로서, 와이퍼 시스템을 주위 환경 조건에 따라 적절하게 작동되도록 한 자동차용 와이퍼 자동 제어 시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic wiper control system for an automobile, and more particularly to an automatic wiper automatic control system for a vehicle so that the wiper system is properly operated according to ambient environmental conditions.

통상적으로, 와이퍼 시스템은 크게 와이퍼 암 구동용 모터와, 이 모터에 의하여 소정의 각도로 반복 구동되는 와이어 암과, 이 와이퍼 암에 장착되어 창을 닦아주는 와이어블레이드로 구성되어 있다.Typically, a wiper system is composed of a wiper arm driving motor, a wire arm repeatedly driven at a predetermined angle by the motor, and a wire blade mounted on the wiper arm to clean a window.

상기 와이퍼 시스템은 주변 조건에 따라 그 작동상태를 자동으로 제어하여 편의성을 증대시키는 추세에 있고, 그 일례로서 다음과 같은 와이어 시스템 제어장치(미국특허 5773946)가 이미 출원되어 있는 바, 이를 첨부한 도 3을 참조로 설명하면 다음과 같다.The wiper system has a tendency to increase convenience by automatically controlling its operating state according to ambient conditions. As an example, the following wiper system controller (US Patent 5773946) has already been filed. Referring to 3 as follows.

우천시에 빗물이 전면글래스에 부딪히면, 이때 빗물의 부딪히는 소음을 음향감지기(23)에서 감지하는 동시에 전기신호로 변환하여 증폭기(14)로 전기신호를 보내게 되고, 증폭기(14)에서는 수신된 전기신호를 증폭시키는 동시에 여과기(12)로 증폭된 전기신호를 보내 여과되도록 한다.When rainwater hits the front glass in rainy weather, the sound of rainwater is detected by the acoustic sensor 23 and converted to an electrical signal at the same time to send an electrical signal to the amplifier 14, the amplifier 14 receives the received electrical signal At the same time to amplify the filter to send an amplified electric signal to the filter 12.

상기 여과된 음향 전기신호는 전압계(16)에서 그 전압이 측정되고, F/V변환기(20)에서 전압대비 주파수가 측정된 후, 비교기(18,20)로 흘러간다.The filtered acoustic electrical signal is measured at a voltmeter 16 and a frequency to frequency is measured at the F / V converter 20 and then flows to the comparators 18 and 20.

다음으로, 상기 전기신호는 비교기(18,20)에서 기준 데이타와 비교된 후, 논리제어회로(22)로 입력되는 바, 이때 논리제어회로(22)는 그 전달받은 신호에 따라 한 번 닦기(24), 연속 닦기(25)등의 신호를 출력하게 된다.Next, the electrical signal is compared with the reference data in the comparators 18 and 20, and then input to the logic control circuit 22, where the logic control circuit 22 is wiped once according to the received signal. 24), a signal such as continuous wipe 25 is outputted.

한편, 상기 와이퍼 시스템 제어장치는 축전지(2)에서 공급되는 전원을 전력조정회로(6)에서 조정하여 사용하고, 간헐식 창닦기는 운전자가 간헐식 창닦기 제어(4)를 조정하여 수행한다.On the other hand, the wiper system controller is used by adjusting the power supplied from the battery 2 in the power regulation circuit 6, the intermittent window cleaning is performed by the driver to adjust the intermittent window cleaning control (4).

그러나, 상기와 같은 종래의 와이퍼 시스템 제어장치는 한 두개의 정보(전면글래스에 부딪히는 빗물의 음향)로 자동 창닦기가 수행됨에 따라, 주변조건이 복잡해질 경우 오작동을 하게 되는 문제점이 있다.However, the conventional wiper system control device as described above has a problem in that automatic window cleaning is performed with one or two pieces of information (sound of rain water hitting the front glass), which causes a malfunction when the surrounding conditions become complicated.

즉, 주위의 차가 지나가면서 소음을 발생하여도 와이퍼가 오작동하게 되어 운전자의 시계를 오히려 방해하게 되고, 이러한 오작동시 운전자는 와이퍼의 구동을 멈추게 하는 스위치 조작을 반복해서 실행함에 따라 편의성 및 신뢰성이 크게 저하되는 문제점이 있다.In other words, even if the noise around the car passes by, the wiper malfunctions and interferes with the driver's watch. In the case of such a malfunction, the driver repeatedly performs the switch operation to stop the wiper. There is a problem of deterioration.

또한, 계속되는 오작동으로 와이퍼 시스템의 성능과 내구성이 크게 저하되는 단점이 있다.In addition, there is a disadvantage that the performance and durability of the wiper system is greatly reduced due to the continuous malfunction.

따라서, 본 발명은 상기와 같은 점을 감안하여, 전면글래스에 대하여 와이퍼 블레이드가 주변환경 조건에 꼭 맞는 속도로 작동되도록 주변 환경 조건을 최대한 감지하는 감지부와, 감지된 신호에 따라 와이퍼 블레이드의 최적 구동속도를 게산하고 결정하는 데이타 처리부와, 결정된 와이퍼 블레이드 구동속도에 따른 전력량을 결정하는 구동부로 구성된 인공지능형의 자동차용 와셔액 자동 제어 시스템을 제공하는데 그 목적이 있다.Therefore, in view of the above, the present invention, the detection unit for maximally detecting the ambient environmental conditions so that the wiper blade is operated at a speed that fits the environmental conditions with respect to the front glass, and the optimum of the wiper blades according to the detected signal An object of the present invention is to provide an artificial auto washer liquid control system including a data processor for calculating and determining a driving speed and a driver for determining an amount of power according to the determined wiper blade driving speed.
