汽车智能化电动助力转向系统控制策略

Control Strategy of Electric Power Steering System in Intelligent Automobile

转向系统作为汽车的核心部件,其在汽车智能化发展中起着重要的作用。但是传统的转向系统已经无法满足智能化要求,电动助力转向系统的引入势在必行。通过车速、轮速、转速等外部信号的获取,以及对输出扭矩的控制,实现了转向系统不同功能的智能化控制策略。此外,通过不同助力曲线的预先设定,可以给驾驶员提供不同的驾驶体验。结果表明,电动助力转向系统的智能化控制策略具有良好的操纵稳定性和行驶安全性,为实现汽车智能化发展提供了有力保障。

As the core component of automobile,steering system plays an important role in the development of automobile intelligence.However,the traditional steering system has been unable to meet the intelligent requirements,the introduction of electric power steering system is imperative.Intelligent control strategies for different functions of steering system are realized by acquiring external signals such as vehicle speed,wheel speed and rotation speed,and controlling output torque.In addition,different driving experiences can be provided to drivers by presetting different boost curves.The results show that the intelligent control strategy of electric power steering system has good handling stability and driving safety,which provides a strong guarantee for the intelligent development of automobiles.
