Marcus Nolte, Richard Schubert, Cordula Reisch, Markus Maurer

摘要:

基于模型的方法在自动驾驶领域越来越受欢迎。这包括运行时算法,如模型预测控制,以及用于验证自动车辆功能的正式和模拟方法。在这种趋势下,模型的质量对于自动驾驶汽车的安全性至关重要。从模型理论建立的工具,可用于确保模型的质量是不确定性和敏感性分析[1]。本文对单轨和双轨车辆动力学模型进行灵敏度分析,以了解模型在不同运行条件下的行为。我们比较的模型,指出最重要的发现获得的参数的敏感性,并提供可能的应用所获得的见解的例子。

英文摘要:

Model-based approaches have become increasingly popular in the domain of automated driving. This includes runtime algorithms, such as Model Predictive Control, as well as formal and simulative approaches for the verification of automated vehicle functions. With this trend, the quality of models becomes crucial for automated vehicle safety. Established tools from model theory which can be applied to assure model quality are uncertainty and sensitivity analysis [1]. In this paper, we conduct sensitivity analyses for a single and double track vehicle dynamics model to gain insights about the models' behavior under different operating conditions. We compare the models, point out the most important findings regarding the obtained parameters sensitivities, and provide examples of possible applications of the gained insights.
