The present invention provides an electric wiper system for a railway vehicle, having an overload prevention function. According to an embodiment of the present invention, the electric wiper system for a railway vehicle, having the overload prevention function, includes: a wiper driving unit including a wiper installed in a window for a railway vehicle, a driving motor driving the wiper, and a linkage structure connecting the driving motor and the wiper; a current measuring unit measuring an electric current of the driving motor in real time; and a wiper control device controlling a motion of the driving motor. The wiper control unit changes a rotation direction of the driving motor into an opposite direction and moves the wiper to an initial position of the wiper when an electric current value of the driving motor measured by the current measuring unit is measured as a threshold value or greater.

    본 발명은 과부하 방지 기능을 갖는 철도 차량용 전기식 와이퍼 시스템을 제안한다. 본 발명의 일 실시예에 따른 과부하 방지 기능을 갖는 철도 차량용 전기식 와이퍼 시스템은 철도 차량용의 창문에 배치된 와이퍼, 상기 와이퍼를 구동하는 구동 모터 및 상기 구동 모터와 와이퍼를 연결하는 링키지 구조물을 포함하는 와이퍼 구동부; 상기 구동 모터의 전류를 실시간으로 측정하는 전류측정부; 및 상기 구동 모터의 동작을 제어하는 와이퍼 제어 장치를 포함하되, 상기 와이퍼 제어 장치는 상기 전류 측정부에서 측정된 상기 구동 모터의 전류값이 임계값 이상으로 측정되면, 상기 구동 모터의 회전 방향을 반대 방향으로 전환하고, 상기 와이퍼의 초기 위치로 상기 와이퍼를 이동시키는 것을 특징으로 한다.
