摘要: 以无人驾驶小巴为代表的客运自动驾驶工具在公交微循环中发挥着重要作用,为实现无人驾驶技术的商业化规模运用,除了传统的车辆性能测试外,还需评估其在复杂场景下的表现。由于测试数据缺乏,评价模型适用场景单一和评价方法主观等问题,导致以往评价偏差较大。本文针对无人驾驶小巴的表现构建综合评价体系,并在实测数据的基础上,采用博弈论组合赋权的 优劣解距离法(Techniquefor Order Preference by Similarity to Ideal Solution, TOPSIS)模型,对车辆在复杂场景下的表现进行综合评价。选取驾驶安全性、乘坐舒适性、车辆智能性及车辆高效性这4个评价维度,并细分为12个客观评价指标。首先,通过实地测试采集无人驾驶小巴在运行场景中的数据;其次,利用基于博弈论的组合赋权法,对层次分析法和熵权法获得的权重进行组合;最后,为验证模型的有效性,运用TOPSIS模型对3条具有不同复杂度的测试路线进行综合评价值的计算。结果显示,无人驾驶小巴表现评价中,准则层的重要程度排序为车辆智能性、驾驶安全性、乘坐舒适性、车辆高效性,指标层敏感指标则为自动驾驶状态、平均角速度。基于博弈论组合赋权的TOPSIS模型对不同场景复杂度路线进行的无人驾驶小巴表现评价结果与实际运行情况一致,展示了方法的有效性。

Abstract: Autonomous minibuses play an important role in the micro-circulation of public transportation. To achieve commercial application of autonomous driving technology, in addition to traditional vehicle performance tests, it is also necessary to evaluate their performance in complex scenarios. Due to the lack of test data, the limited applicability of evaluation models, and the subjectivity of evaluation methods, previous evaluations have shown significant biases. This study developed a comprehensive evaluation system for the performance of autonomous minibuses and conducted a comprehensive evaluation based on field test data using a TOPSIS model combined with game theory weighting. Four evaluation dimensions were selected: driving safety, ride comfort, vehicle intelligence, and vehicle efficiency, which were further divided into 12 objective evaluation indicators. First, data were collected through field tests in the operating scenarios of autonomous minibuses. Second, the game theory-based combined weighting method was used to combine the weights obtained from the analytic hierarchy process and the entropy weighting method. Finally, to verify the effectiveness of the model, the TOPSIS model was used to calculate the comprehensive evaluation values of three test routes with different complexity. The results show that in the performance evaluation of autonomous minibuses, the order of importance at the criterion level is vehicle intelligence, driving safety, driving comfort, and vehicle efficiency, while the sensitive indicators at the index level are autopilot state and average angular velocity. The results of the performance evaluation of autonomous minibuses on routes with different scenario complexities using the game theory based combined weighting TOPSIS model were consistent with the actual operating conditions, demonstrating the effectiveness of the method.
