摘要

针对四轮电机驱动电动汽车(EV)具有四轮独立转向的特点，提出了一种具有死区执行机构的电动助力转向控制方法。根据实验数据推导了执行机制的数学模型。设计了“死区逆变换补偿”，消除了死区带来的不良影响。在真实汽车环境中的实验验证了该方法的有效性。

A novel control method for electric power steering system based on dead-zone Inverse Transforming Compensation in a four-in-wheel-motor drive Electric Vehicle

Since the four-in-wheel-motors drive (FWMD) Electric Vehicle (EV) has a 4-wheel independent steering, this paper presents a novel control method for an electric power steering system with a dead-zone execution mechanism. A mathematical model was derived for execution mechanisms from the empirical data. A “Dead-zone Inverse Transforming Compensation” was designed to eliminate ill effects caused by dead-zone. The experiment in a real car environment proves that the proposed method.
