摘要
线路保持性是汽车稳定性的重要性能之一,目前该性能还没有被纳入车辆性能的前期设计开发阶段,主要原因就是车辆模型无法进行汽车线路保持性的动态仿真,缺乏对体现该性能关键影响因素的描述。针对车辆模型的不足,对汽车线路保持性的机理进行了分析,在此基础上对该性能影响最为主要的转向系统的建模方法提出要求,并通过典型动态行驶工况验证所建模型的有效性,从而在概念设计阶段就可以对该性能展开研究,大大提升车辆稳定性的设计开发稳健性。
Lane keeping is the key performance of vehicle stability, now the property has not been included in the early stages of vehicle design. Vehicle dynamic process simulation cannot be done which is due to the lack of key factors of the performance. For the shortcoming of vehicle model,it has analyzed the modeling method of steering system which has main effect on lane keeping performance and verified the effectiveness of vehicle model through typical driving conditions. In this way, the performance can be done in the concept design stage, which will enhance the design and development robustness of vehicle stability.
