A driver in road hypnosis has two different types of characteristics. One is the external characteristics, which are distinct and can be directly observed. The other is internal characteristics, which are indistinctive and cannot be directly observed. The eye movement characteristic, as a distinct external characteristic, is one of the typical characteristics of road hypnosis identification. The electroencephalogram (EEG) characteristic, as an internal feature, is a golden parameter of drivers' life identification. This paper proposes an identification method for road hypnosis based on the fusion of human life parameters. Eye movement data and EEG data are collected through vehicle driving experiments and virtual driving experiments. The collected data are preprocessed with principal component analysis (PCA) and independent component analysis (ICA), respectively. Eye movement data can be trained with a self-attention model (SAM), and the EEG data can be trained with the deep belief network (DBN). The road hypnosis identification model can be constructed by combining the two trained models with the stacking method. Repeated Random Subsampling Cross-Validation (RRSCV) is used to validate models. The results show that road hypnosis can be effectively recognized using the constructed model. This study is of great significance to reveal the essential characteristics and mechanisms of road hypnosis. The effectiveness and accuracy of road hypnosis identification can also be improved through this study.
处于道路催眠状态的驾驶员具有两种不同类型的特征。一种是外部特征,其较为明显且可直接观察到。另一种是内部特征,其不明显且无法直接观察到。眼动特征作为一种明显的外部特征,是道路催眠识别的典型特征之一。脑电图(EEG)特征作为一种内部特征,是驾驶员状态识别的关键参数。本文提出了一种基于人体生命参数融合的道路催眠识别方法。通过车辆驾驶实验和虚拟驾驶实验收集眼动数据和EEG数据。所收集的数据分别采用主成分分析(PCA)和独立成分分析(ICA)进行预处理。眼动数据可使用自注意力模型(SAM)进行训练,EEG数据可使用深度信念网络(DBN)进行训练。通过堆叠方法将两个训练好的模型相结合,可构建道路催眠识别模型。使用重复随机子采样交叉验证(RRSCV)对模型进行验证。结果表明,使用所构建的模型能够有效识别道路催眠状态。本研究对于揭示道路催眠的本质特征和机制具有重要意义。通过本研究还可提高道路催眠识别的有效性和准确性。
