摘要
电动助力转向是汽车动力转向的新技术与新结构,助力控制是电动助力转向的基本控制策略,并决定电动助力转向的助力特性。着重讨论了电动助力控制的一般过程、电动机目标电流的决策方法、电动机电流的控制策略等问题。台架试验表明,提出的控制策略是有效的,对电动助力转向的开发有指导意义。
Electric power steering is a new automotive power steering technology and configuration.Power control is the basic control strategy of the electric power steering and determines characteristics of the electric power steering.In the paper,the general process of the electric power steering control,the decision-making method of the objective electric cur -rent of the electric motor and control strategy of the electric current of the electric motor,etc.are discussed emphatically.It is shown by bench tests that the presented control strategy is valid,and has a guiding significance to development of elec-tric power steering.
