Abstract
En 中文
This study presents the design and evaluation results of a dual-sensing angle detection module that integrates inductive and Hall effect sensors to improve the accuracy and reliability of steering angle detection in automobiles. Unlike dual Hall implementations, the proposed architecture leverages the complementary properties of the two sensing principles. The Hall channel provides high resolution and fast response, while the inductive channel contributes robustness against stray magnetic fields and mechanical tolerances. A compact prototype module was fabricated and tested on a laboratory test stand and in a real vehicle equipped with a steering robot. The results show that the Hall sensor achieved a maximum absolute angular error of 0.8(degrees) and the inductive sensor 0.5(degrees) over a rotation range of -720(degrees) to +720(degrees) and speeds up to 2000(degrees)/s. Vehicle-based evaluations confirmed consistent performance, though errors increased up to 1.5(degrees) due to installation misalignment and gear backlash (similar to 0.135(degrees)). These findings highlight not only the benefits but also the practical limitations of the dual-sensing design; they provide valuable insights into the practical application of the module beyond simple module-level verification.
