Integrated Framework for Test and Evaluation of Autonomous Vehicles

Autonomous vehicles must pass effective standard tests to verify their reliability and safety.Accord-ingly,it is very important to establish a complete scientific test and evaluation system for autonomous vehicles.A comprehensive framework incorporating the design of test scenarios,selection of evaluation indexes,and estab-lishment of an evaluation system is proposed in this paper.The aims of the system are to obtain an objective and quantitative score regarding the intelligence of autonomous vehicles,and to form an automated process in the future development.The proposed framework is built on a simulation platform to ensure the feasibility of the design and implementation of the test scenarios.The design principle for the test scenarios is also presented.To reduce subjective influences,the proposed framework selects objective indexes from four aspects:safety,comfort,driving performance,and standard regulations.The order relation analysis method is adopted to formulate the index weights,and fuzzy comprehensive evaluation is used to quantify the scores.Finally,a numerical example is provided to visually demonstrate the evaluation results for the autonomous vehicles scored by the proposed framework.
