车辆转向及操稳风格的研究与设定

Research and Setting of Vehicle Steering and Handling Styles

本文对车辆转向及操稳风格及设定进行了研究。首先,分析并阐述了常见的转向及操稳在某些指标两极的主观感受。然后,选择了与主观感受密切关联的9个车辆动力学指标作为研究对象,并结合市场反馈,确定这9个客观指标对应的主观感受,建立主客观之间的关联,并按照GB/T 6323-2014汽车操纵稳定性试验方法对二十余辆车的9组特性指标进行了客观试验。最后,分析9组指标的客观试验的结果分布可知,车辆的转向及操稳可以划分为舒适和运动两种风格,针对两种性能风格分别制定了不同的客观指标范围。该研究解决了车辆操稳性能开发过程中常见的主观感受与客观测试相互脱节的现状,该研究成果可以有效指导底盘调校工作,有利于建立品牌的转向及操稳风格的调性。

In this paper, vehicle steering and handling styles and setting method are studied. First of all, it analyzes and expounds the common subjective feelings of steering and handling at the two extremes of some indicators. Then, choose 9 indexes of vehicle dynamics as the research objects which closely associated with subjective feeling, and according to the after sale feedback, state explicitly the nine objective indicators of subjective feeling, also establish the contact between them, and 9 sets of objective characteristic of more than twenty vehicles were tested according to the “GB/T 6323-2014: Controllability and stability procedure for automobile”. Finally, by analyzing the distribution of the results of the 9 groups of objective tests, it can be seen that the steering and handling of vehicles can be divided into comfort and movement styles, and different objective index ranges are formulated for the two performance styles. The research solves the disconnection between subjective feeling and objective test in the development process of vehicle handling performance, and the re-search results can effectively guide the chassis tuning, which is beneficial to the establishment of brand’s steering and handling image.
