Confidence Evaluation Method for Autonomous Driving Simulation Testing
摘要
Abstract
As simulation testing plays a more important role in the development process of autonomous driving technology,the confidence level of simulation testing has become a key focus in the industry.However,there is no unified metric or evaluation framework for measuring simulation test confidence.To address this gap,this paper proposes a confidence evaluation method based on two dimensions:timing and trend.Firstly,an objective characterization index set was constructed to describe the vehicle s control timing and the variation trends of the control parameters.Secondly,four typical scenarios covering both longitudinal and lateral control were designed,with six sets of experiments conducted for each scenario.A software-in-the-loop(SIL)simulation platform was developed to perform the simulation tests.Finally,the Pearson correlation coefficient was used to evaluate the consistency of parameter trends,and the relative error was used to assess the consistency of control timing.The results show that the correlation coefficients of the variation curves for both lateral and longitudinal control parameters are all above 0.95,and the relative errors of the control timing indicators are below 5％,which is within the acceptable range.关键词
