Abstract

본 발명은 자동차 후방감시경의 작동장치에 관한 것으로서, 기준전압을 제공하는 정전압회로(5)로부터의 각 레벨전압과, 경사각센서로부터의 현재 경사각의 정도를 나타내는 측정전압(V1,V2,V3)을 비교기(10,11,12)에서 비교하여, AND논리회로(20,21,22)를 경유하여, 상기 각 논리값에 상응하는 작용함수를 가지는 마이컴(C.P.U:6)이 적의의 시간과 회전각으로서 실내경(2)을 구동하는 모우터(30)를 구동제어하고, 클럭발생기(6)로부터의 발생된 클럭을 일정시간동안 카운트회로(7)에서 카운트하여 이 카운트신호에 의하여 일정시간동안 이루어지는 것을 특징으로 하여; 경사로에서의 측정전압과 기준전압을 비교하여 경사상태인가를 판별하여 후방감시경을 소정의 시간과 각도로 회전하게 함으로서, 고개를 후방으로 돌리거나 별도로 수동으로 후방감시경을 작동하지 않더라도 일정시간 동안 후방감시경을 회전구동하게 하여 후방을 감시할 수 있게 하는 것을 목적으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an operating apparatus of a rearview vehicle, and includes measuring the level voltages from the constant voltage circuit 5 that provides a reference voltage and the measurement voltages V1, V2, V3 indicating the degree of the current tilt angle from the tilt angle sensor. Compared by the comparators 10, 11, and 12, the microcomputer (CPU) 6 having an action function corresponding to each of the logic values via the AND logic circuits 20, 21, and 22 is subjected to an appropriate time and rotation angle. As a result, the motor 30 driving the indoor mirror 2 is driven and controlled, and the clock generated from the clock generator 6 is counted by the count circuit 7 for a predetermined time, and the count signal is generated for a predetermined time. Characterized in that; By comparing the measured voltage and the reference voltage on the slope, it is determined whether the state is inclined and rotates the rear view mirror at a predetermined time and angle, so that even if the head is turned backward or not operated manually, It aims to be able to monitor the rear by rotating the rear surveillance.
