摘要

方向盘±720°绝对角位置的测量是轮式驱动电动汽车转矩协调控制解决方案的关键之一。通过16位处理器dsPIC30F6010A与两片TLE5012通信

设计了一种基于iGMR的±720°绝对角位置非接触式传感器

并可通过外部中断设置方向盘的回正零点。给出了该传感器的具体实现方案

包括2个从动齿轮的齿数设计

绝对角位置的计算方法;并对单SPI接口通信在调试时存在的问题

给出了解决办法;最后试制了样机

进行了实际转角检测

并对实验结果进行了误差分析。实验证明:该传感器能达到方向盘±720°绝对角位置的测量要求

为轮式驱动电动汽车转矩协调控制打下了基础。

Abstract

The detection of steering angular position range is ±720°

is one of the key part of solution to torque coordinating control of in-wheel motor driven electric vehicle（EV）.A novel sensor structure based on dsPIC30F6010A communicating with two TLE5012 is adopted.A±720°absolute angular position contactless sensor based on iGMR is designed

and zero point can be set through external interruption.The implementations of the sensor is given

including the design of two gears

calculation method of absolute angular position

and some debugging problems are also discussed in detail.The error analysis of experimental results is presented.The result proofs that this sensor can meet the demands of ±720°absolute angular position detection

laying the foundation for torque coordinating control of in-wheel motor driven EV.
