介绍了采用绝对值型编码器测量转角的方法，并给出了传感器与电子控制单元之间的接口电路。
The method of using the absolute rotary encoder to measure the steering angle is suggested. At the same time, the circuit wh…
为全面实现以上原则通过理论分析指出采用偏差输入将优于采用绝对值输入；采用时间常数可变的时限电路将优于采用平方电路。
It proves that it is superior to use the "deviation input" to the "absolute-value input" and better to use time circuit with variable time constant than to use square circuit.
如果去掉C2，电路就不再具有平均值滤波功能，只是一个精密全波整流器，如果去掉C1，电路就变成求绝对值的电路。
Deletion of C2 removes the averaging function and provides a precision full-wave rectifier, and deletion of C1 provides an absolute value generator.
