摘要
为了改善汽车转向系的回正特性,采用了一种基于转向盘角速度的查表闭环控制策略,设计开发了EPSECU硬件和软件程序。在实验台上进行了实验,结果表明,该控制策略可顺利的使方向盘回至接近中点位置,且缓和了回正过度的现象。
The close-loop control strategy by searching table for steering wheel aligning based on angle speed of steering wheel is proposed to improve the aligning ability of electric power steering system,and the system’s hardware and software are designed.The experiment results show that the control strategy can make the steering wheel return to the center smoothly and mitigate the aligning overshoot.
