摘要
文中研究了汽车转向路感的形成,并对系统进行了动力学建模,分析了电动助力转向系统的路感特性,研究了电动助力转向系统路感的影响因素。提出了用自适应遗传算法改善电动助力转向系统的路感。仿真结果表明,自适应遗传算法具有搜索速度快,收敛精度高等优点,基于自适应遗传算法优化的系统参数提高了系统的转向路感。
The formation and definition of the road feel of steering system is researched in this paper, the system composition of the electric power steering system is introduced, the road feel characteristic and the influence factors on the electric power steering system (EPS) are analyzed. The EPS road feel is improved by the adaptive genetic algorithm. The simulation results indicated that the adaptive genetic algorithm had the advantages of faster and higher precision, the optimization of the EPS system parameters effectively improved the road feeling.
