Abstract

본 발명은 위드실드 글래스 상의 습도를 감지하여 기준습도 이상이 되는 경우 자동으로 와이퍼를 작동시킬 수 있는 차량용 오토 와이퍼 시스템 및 그 방법에 관한 것이다.The present invention relates to an auto wiper system for a vehicle and a method for automatically activating a wiper when a humidity on a weed-shielded glass is sensed and reaches a reference humidity.

본 발명 시스템은 와이퍼 링크 어셈블리의 링크작동에 따라 한쌍의 와이퍼 블레이드(17A, 17B)를 윈드실드 글래스(13) 표면을 따라 상하로 선회구동 시키는 한쌍의 와이퍼 암(15A, 15B)을 구비한 윈드실드 와이퍼 시스템에 있어서, 윈드실드 글래스(13)의 적어도 일이상의 개소에 설치되어 습도를 감지하기 위한 적어도 일이상의 습도센서(7A-7D)와, 모터의 구동주기를 설정하기 위한 주기조절 스위치(9)와, 상기 습도센서중 어느 하나로부터 검출된 글래스 습도값이 내부의 기준설정 습도값 보다 클경우에 상기 설정된 주기로 모터구도신호를 발생하기 위한 제어수단(1, 3, 5)과, 상기 모터구동신호에 따라 정역 회전되어 상기 와이퍼 링크 어셈블리를 통하여 와이퍼 암을 작동시키는 구동수단(11)으로 구성되는 것을 특징으로 한다.The system of the present invention includes a windshield (not shown) having a pair of wiper arms 15A and 15B for pivotally driving a pair of wiper blades 17A and 17B up and down along the surface of the windshield glass 13 in accordance with the link operation of the wiper link assembly A wiper system comprising at least one humidity sensor (7A-7D) provided at at least one or more positions of a windshield glass (13) for sensing humidity, a cycle adjustment switch (9) for setting a drive cycle of the motor, And control means (1, 3, 5) for generating a motor composition signal at the set period when the glass humidity value detected from any one of the humidity sensors is greater than an internal reference humidity value, And a driving means (11) for rotating the wiper arm through the wiper link assembly.

따라서 비가 오다 그쳤다를 불규칙하게 반복하거나 또는 비오는 양의 변화가 심하게 이루어지는 경우에도 운전자가 계속적으로 스위치의 온/오프 조작을 하여야 하는 불편한 점이 해소될 수 있다.Therefore, it is possible to solve the inconvenience that the driver must continuously turn on / off the switch even when irregular repetition of rain stops or when the amount of rain fluctuates severely.
