摘要
汽车配备电动助力转向(EPS)系统后,如何评价其转向性能目前还没有公认的标准。提出了EPS系统汽车转向性能的主观评价方法,并从原地转向和车辆行驶转向2个方面进行综合评价。探讨了相应的主观评价项目、计分方法和综合评价指标的评定。对所开发的EPS系统进行了转向性能道路评价试验并对被测试车辆进行主观评价,得到了合理的评价结果。
There is still not a commonly accepted standard on how to evaluate the steering performance of a vehicle equipped with electric powering steering （EPS） system. The subjective evaluation of steering performance of vehicles equipped with EPS is introduced and the comprehensive evaluation of the performance under two kinds of driving conditions with the vehicle at stationary state （fixed-site steering） and at running state is raised. Besides, we investigated the corresponding subjective evaluation items, scoring approaches and calculation of comprehensive evaluation index. Subjective evaluation of testing vehicle has been presented after the experiment of steering performances and the results are reasonable. The subjective evaluation method is helpful to establish evaluation criterion of the EPS steering performance and assist the development of EPS.
