电动助力转向性能评价研究

Study on evaluation of steering performance of EPAS

建立了一套适合于汽车电动助力转向系统的评价指标体系。提出了以稳态回转、转向轻便性、转向回正性、汽车轮胎抓地能力、转向盘中间位置操纵稳定性等作为汽车电动助力转向系统转向性能的评价指标,并对其进行了探讨。对汽车电动助力转向系统的设计、控制策略以及基本控制参数的确定有一定的指导意义。

Established a set of evaluation indexes for electrical power assisted steering, proposed to take steady static circular, steering portability, steering returnability, vehicle ground adhesion ability, oncenter handling performance and so on as evaluation indexes,and the corresponding evaluation indexes are also discussed. It has the certain instruction significance for designing electrical power assisted steering, determination of control strategy and the basically controlled parameters.
