The invention discloses an automobile risk potential field assessment method based on a driving style coefficient. On the basis of the risk potential field, the driving style coefficient obtained through driving behavior data and trajectory prediction are introduced, the risk is judged more accurately through the proper risk potential field, and the limitation and generalization of a traditional risk potential field method are overcome, especially the defects in the aspect of considering individual differences and behavior characteristics of drivers are overcome. According to the method, the driving style characteristics are accurately extracted by analyzing the existing driving data of the driver, and are integrated into the risk potential field model, so that the identification capability of the risk potential field on the driving safety is improved, the risk level of the driver under various driving conditions can be more comprehensively and accurately evaluated, and the driving safety of the vehicle is improved.

    本发明公开了一种基于驾驶风格系数的汽车风险势场评估方法。在风险势场的基础上引入通过驾驶行为数据获取的驾驶风格系数和轨迹预测,使用合适的风险势场更加准确地判断风险,克服了传统风险势场方法的局限性与泛化性,特别是在考虑驾驶员个体差异和行为特征方面的不足。本发明通过对驾驶员已有驾驶数据的分析,精确地提取出驾驶风格特征,并将其整合到风险势场模型中,从而提高了风险势场对驾驶安全的鉴别能力,能够更全面、准确地评估驾驶员在各种驾驶条件下的风险水平,进而提升车辆驾驶安全性。
