摘要
随着汽车工业迅猛发展,车辆状况完好程度的检测势在必行。为了解决汽车方向盘角度检测精度不够的问题,本文提出了利用4倍频提高精度的方法,设计了相应的汽车转向参数检测仪器中的角度传感器。该角度传感器采用光电编码器和Xilinx的FPGA器件全新设计,实现了汽车方向盘角度的高精度测量。实际测量表明该角度传感器全量程的最高分辨率达到0.09°。
With the rapid development of automobile industry, detection of the vehicle condition is imperative. In order to improve the detection accuracy of car steering wheel angle, the paper describes the work including the method using four multipliers to improve the accuracy and how to complete the design for angle sensor steering parameter detection equipment. It is brand new to do design using photo-electric encoder and the FPGA devices of Xilinx. The high-precision measurement of the automobile steering wheel angle is realized. And the data in practice shows that the whole point of the range can be measured with a resolution 0. 09°.
