본 발명은 차량용 와이퍼 모터 구동방법에 관한 것으로서, 더욱 상세하게는 운전자가 전방을 주시할 때 시선이 미치는 주시영역 범위내에 위치하는 전방유리창의 표면의 청결도를 유지하여 항상 깨끗한 시야를 확보할 수 있게 하는 와이퍼 모터 구동방법에 관한 것이다. The present invention relates to a vehicle wiper motor driving method, and more particularly, to maintain the cleanliness of the surface of the windshield positioned within the gaze range of the gaze when the driver gazes at the front to ensure a clear view at all times. It relates to a wiper motor driving method.
일반적으로, 차량에는 비가 오는 등의 경우에 운전자의 시야를 선명하게 확보하기 위하여, 차량의 전방유리창에 빗물을 강제적으로 걷어내기 위한 와이퍼가 설치되어 있다.In general, in the case of rain or the like, a wiper for forcibly removing rainwater is provided on the windshield of the vehicle in order to secure the driver's view clearly.
한편, 상기의 윈도우 와이퍼는 필요한 경우에 운전자의 조작에 의해서 작동되는 것으로서, 와이퍼를 작동시킬 때에는 전방유리에 빗물 등의 물을 걷어내는 경우와, 전방유리에 부착된 이물질을 걷어내는 경우로 구분된다.On the other hand, the window wiper is operated by a driver's operation when necessary, and when the wiper is operated, it is divided into a case of removing water such as rain water from the windshield and a case of removing foreign matter attached to the windshield. .
먼저, 물을 걷어낼 경우에는 멀티 펑션 스위치에 설치된 와이퍼 스위치를 동작시키면, 상기 와이퍼가 전방유리의 표면에 접촉된 상태로 회동되면서 운전자의 시야를 확보하게 된다.First, when the water is removed, when the wiper switch installed in the multi-function switch is operated, the wiper is rotated in contact with the surface of the windshield to secure the driver's view.
또한 전방유리에 부착된 이물질을 걷어낼 경우에는 전방유리의 표면으로 워셔액이 분사되도록 멀티 펑션 스위에 설치된 워셔 스위치를 조작하면 워셔탱크에 저장된 워셔액이 전방유리의 표면으로 분사됨과 동시에 와이퍼가 동작되어 운전자의 시야를 확보하게 된다.In addition, when removing the foreign matter attached to the windshield, the washer switch installed in the multi-function switch is operated so that the washer fluid is sprayed to the surface of the windshield. To secure the field of view.
한편, 와이퍼는 전방유리에 접촉된 상태로 동작되므로 그 접촉면에 수분(물 또는 워셔액)이 없을 경우에 접촉력이 증가하여 와이퍼를 동작시키는 와이퍼 모터에 과부하가 작용하게 되어 와이퍼 모터의 사용수명이 단축됨은 물론, 와이퍼 및 전방유리의 표면이 손상되는 문제점이 있었다.On the other hand, since the wiper operates in contact with the windshield, when there is no water (water or washer fluid) on the contact surface, the contact force increases, thereby overloading the wiper motor that operates the wiper, thereby reducing the service life of the wiper motor. Of course, there was a problem that the surface of the wiper and the windshield is damaged.
본 발명은 상기한 문제점을 해결하기 위하여 발명한 것으로서, 그 목적은 운전자에 의해서 워셔 스위치가 조작될 때 워셔액 탱크에 저장된 워셔액을 분사시키 는 워셔 모터에 인가되는 전류값을 측정하여 와이퍼의 동작을 제어함에 따라, 와이퍼 및 전방유리의 손상을 방지할 수 있는 차량용 와이퍼 모터 구동방법을 제공함에 있다.The present invention has been invented to solve the above problems, the object is to control the operation of the wiper by measuring the current value applied to the washer motor to inject the washer fluid stored in the washer fluid tank when the washer switch is operated by the driver Accordingly, to provide a vehicle wiper motor driving method that can prevent damage to the wiper and the windshield.
상기 목적을 달성하기 위한 본 발명의 특징적인 구성을 설명하면 다음과 같다.Referring to the characteristic configuration of the present invention for achieving the above object is as follows.
본 발명의 차량용 와이퍼 모터 구동방법은 멀티 펑션 스위치에 설치된 워셔 스위치를 조작하면 워셔탱크에 저장된 워셔액이 분출되도록 워셔 모터가 동작되는 단계와, 상기 워셔 모터가 동작될 때 전류센서에 의해서 워셔 모터에 인가되는 전류값을 측정하는 단계와, 상기 워셔탱크에 워셔액이 저장된 상태에서 인가되는 기준 전류값과 전류센서에서 측정되는 측정 전류값을 비교하는 단계와, 상기 측정 전류값이 기준 전류값보다 크거나 동일할 경우에는 와이퍼 모터를 동작시키는 단계 및 상기 측정 전류값이 기준 전류값보다 작을 경우에는 와이퍼 모터를 정지시키는 단계를 포함하여서 된 것이다.In the vehicle wiper motor driving method of the present invention, when the washer switch installed in the multi-function switch is operated, the washer motor is operated to eject the washer fluid stored in the washer tank, and when the washer motor is operated, the washer motor is applied to the washer motor by the current sensor. Measuring a current value, comparing a reference current value applied while the washer fluid is stored in the washer tank with a measured current value measured by the current sensor, and the measured current value is greater than or equal to the reference current value In this case, the step of operating the wiper motor and the step of stopping the wiper motor when the measured current value is less than the reference current value.
이와 같은 특징을 갖는 본 발명을 상세하게 설명하면 다음과 같다.Referring to the present invention having such characteristics in detail as follows.
도 1은 본 발명에 따른 와이퍼 모터 구동방법을 설명하기 위한 흐름도이다.1 is a flowchart illustrating a wiper motor driving method according to the present invention.
여기에서 참조되는 바와 같이 본 발명은 전방유리 표면의 물을 걷어내기 위하여 멀티 펑션 스위치에 설치된 와이퍼 스위치를 동작시키면, 상기 와이퍼가 전방유리의 표면에 접촉된 상태로 회동되면서 운전자의 시야를 확보하게 된다.As described herein, when the wiper switch installed in the multi-function switch is operated to remove water from the windshield surface, the wiper rotates in contact with the surface of the windshield to secure the driver's view. .
또한 전방유리에 부착된 이물질을 걷어낼 경우에는 전방유리의 표면으로 워 셔액이 분사되도록 멀티 펑션 스위에 설치된 워셔 스위치를 조작하면 워셔 탱크에 워셔액이 있을 경우에는 도 1에 나타낸 바와 같이 워셔 모터가 정상적으로 동작되므로 상기 워셔모터에는 정상적인 작동전류(약 4.756A)가 인가되는 것이고, 워셔액이 소진된 경우에는 워셔모터가 공진하게 되므로 도 2에 나타낸 바와 같이 비정상적인 작동전류(약 2.11814A)가 인가되는 것이다.In addition, when the washer liquid is removed from the windshield, when the washer switch installed in the multi-function switch is operated so that the washer fluid is injected onto the surface of the windshield, the washer motor is normally operated as shown in FIG. Since the washer is operated, the normal operating current (approximately 4.756 A) is applied to the washer, and when the washer fluid is exhausted, the washer motor is resonated.
따라서, 멀티 펑션 스위치에 설치된 워셔 스위치를 조작하면 워셔탱크에 저장된 워셔액이 분출되도록 워셔모터가 동작될 때 전류센서는 워셔모터에 인가되는 전류값을 측정하는 단계를 수행하게 된다.Therefore, when the washer switch is operated to operate the washer switch installed in the multi-function switch, the current sensor performs a step of measuring a current value applied to the washer motor when the washer motor is operated to eject the washer fluid stored in the washer tank.
상기 단계에서 측정된 전류값은 워셔탱크에 워셔액이 저장된 상태에서 인가되는 기준 전류값과 비교하는 단계를 수행하여 워셔탱크 내부에 워셔액의 유무를 확인하게 되는 것이다.The current value measured in the above step is to compare the reference current value applied in the state in which the washer fluid is stored in the washer tank to check the presence of the washer fluid in the washer tank.
즉, 측정된 전류값이 도 4에 나타낸 바와 같이 일정시간동안 기준 전류값(예 : 3A)보다 크거나 동일할 경우에는 워셔탱크에 워셔액이 저장된 상태이므로 전방유리의 표면에 워셔액이 분사되고 와이퍼가 동작되어 전방유리의 표면의 이물질을 제거하게 되는 것이다.That is, when the measured current value is greater than or equal to the reference current value (for example, 3A) for a predetermined time as shown in FIG. 4, the washer fluid is stored in the washer tank, and the washer fluid is injected onto the surface of the windshield and the wiper is It is operated to remove foreign substances on the surface of the windshield.
한편, 측정된 전류값이 도 5에 나타낸 바와 같이 일정시간동안 기준 전류값(예 : 3A)보다 작을 경우에는 워셔탱크에 워셔액이 소진된 상태이므로 워셔모터와 와이퍼가 정지되는 것이다.On the other hand, when the measured current value is smaller than the reference current value (for example, 3A) for a predetermined time as shown in Figure 5, the washer fluid is exhausted in the washer tank, the washer motor and the wiper are stopped.
이와 같이 본 발명은 차량에 설치된 전방유리 표면의 이물질을 제거하기 위 하여 워셔 스위치를 조작할 때 워셔탱크에 저장된 워셔액의 유무에 따라서, 와이퍼가 동작되므로 워셔액 소진시 불필요한 와이퍼의 동작으로 인한 부품의 손상을 미연에 방지할 수 있는 특유의 효과가 있다.As described above, according to the present invention, when the washer switch is operated to remove foreign substances on the windshield surface installed in the vehicle, the wiper is operated according to the presence or absence of the washer fluid stored in the washer tank. There is a unique effect that can be prevented in advance.
