摘要(Abstract)：

采用可编程线性霍尔位置传感器为角度测量元件的非接触式汽车电子油门踏板正在获得越来越广泛的应用。为了实现产品在线编程校准,企业目前需要依赖购买原装进口的编程器套件,不仅价格高昂,也经常出现各种故障和异常,维护沟通困难、周期长,且通信协议复杂难于掌握使用。针对MicronasTM公司的HAL880型霍尔传感器设计研制了一种电子油门踏板专用编程校准系统,采用线性稳压器LM317和低导通内阻的多路模拟开关ADG1608控制HAL880的编程通道,采用脉冲宽度捕获法读取识别其输出寄存器数值。编程器采用ds PIC33EP256单片机为核心,设计开发了固件程序,采用Visual C#开发上位机通信校准程序。在某型踏板产品上进行实验测试,结果显示该系统能实现传感器的数据读取、曲线校准和编程写入的完整过程。
