Research on scenario-based trustworthiness evaluation method of autonomous vehicles

To meet the demand for trustworthiness evaluation of autonomous vehicles, a scenario-based trustworthiness evaluation method for autonomous vehicles is proposed. The testing scenarios are decomposed into environmental elements and task elements based on evaluation objectives, and a hierarchical structure is established for each part. By defining the complexity and coupling of each element, a method for calculating the complexity coefficient of testing scenarios is obtained. A set of trustworthiness evaluation indicators for autonomous vehicles is proposed, and the complexity coefficient of testing scenarios is incorporated into the comprehensive evaluation results to obtain the trustworthiness evaluation results based on scenarios. A comparison between existing evaluation methods before and after incorporating the complexity coefficient of testing scenarios shows that the scenario-based evaluation method can more objectively reflect the trustworthiness level of autonomous vehicles.
