【摘要】：以夜间环境下的驾驶行为为研究对象,基于驾驶模拟器开展了四类驾驶实验,以及白天、夜间单一驾驶任务实验,以及白天、夜间主从驾驶任务实验。在驾驶员脑电、心电、呼吸、皮电等生理数据和精神负荷主观评价的基础上,运用统计学方法综合分析了驾驶模拟实验过程中的生理参数变量变化规律。结果表明:相比白天行车环境,夜间环境下驾驶员的精神负荷有一定的增加,在执行主从任务的夜间行驶实验中被测试对象感知的主观压力显著增加,且主观压力与主从任务难度成正比关系。心率变异性功率谱密度、脑电负荷水平等生理指标呈现显著性差异,呼吸频率也有一定的变化,呼吸幅度和皮电的指标变化不明显。研究成果可用于夜间环境下的道路交通安全评价。
[Abstract]:Based on the driving simulator, four kinds of driving experiments were carried out, as well as daytime and night single driving task experiments, and daytime and night master-slave driving task experiments. On the basis of physiological data such as EEG, ECG, respiration, skin electricity and subjective evaluation of mental load, the variation of physiological parameter variables in driving simulation experiment was comprehensively analyzed by means of statistical method. The results show that compared with the daytime driving environment, the mental load of the driver in the night environment is increased to some extent, and the subjective pressure perceived by the subjects in the nocturnal driving experiment performed by the master-slave task is significantly increased. The subjective pressure is proportional to the difficulty of the master-slave task. There were significant differences in physiological indexes such as HRV power spectral density, EEG load level and respiratory frequency, but there were no significant changes in respiratory amplitude and skin electrical index. The research results can be used to evaluate the road traffic safety in the night environment.
