Abstract

본 발명은 교차코일형 지시계기의 코일 구동용 사인 및 코사인 함수를 만들기 위한 함수 발생 회로에 관한 것이다.The present invention relates to a function generating circuit for making a sine and cosine function for driving a coil of a cross coil type indicator.

종래의 함수 발생회로는 2개의 교차코일에 인가하는 사인/코사인 함수를 (나)에서와 같이 근사파형으로 만들어 구동하도록구성되어져 있기 때문에 전구간에서 일정한 토오크 특성을 얻을수가 없으며, 지시오차가 크므로 성능저하의 문제점이 있다.Conventional function generators are designed to drive a sine / cosine function applied to two cross coils in an approximate waveform as shown in (b). There is a problem of degradation.

이를 위해 본 발명은 염가의 회로구성으로서 교차 코일형 아날로그 지시계기의 구동장치를 구성할 수가 있고 또한 외부영향에 의한 보상을 손쉽게 할 수가 있음은 물론 0-360°구간에서 선형적인 구동 토오크를 얻을 수 있도록 함을 그 목적으로 한 것으로서 각종 차량에 채용이 가능하다.To this end, the present invention can configure the driving device of the cross-coil analog indicator as an inexpensive circuit configuration, and can easily compensate for the external influence as well as obtain a linear driving torque in the 0-360 ° range. It is intended to be used in various vehicles for this purpose.
