【摘要】：以夜間環(huán)境下的駕駛行為為研究對(duì)象,基于駕駛模擬器開展了四類駕駛實(shí)驗(yàn),以及白天、夜間單一駕駛?cè)蝿?wù)實(shí)驗(yàn),以及白天、夜間主從駕駛?cè)蝿?wù)實(shí)驗(yàn)。在駕駛員腦電、心電、呼吸、皮電等生理數(shù)據(jù)和精神負(fù)荷主觀評(píng)價(jià)的基礎(chǔ)上,運(yùn)用統(tǒng)計(jì)學(xué)方法綜合分析了駕駛模擬實(shí)驗(yàn)過程中的生理參數(shù)變量變化規(guī)律。結(jié)果表明:相比白天行車環(huán)境,夜間環(huán)境下駕駛員的精神負(fù)荷有一定的增加,在執(zhí)行主從任務(wù)的夜間行駛實(shí)驗(yàn)中被測試對(duì)象感知的主觀壓力顯著增加,且主觀壓力與主從任務(wù)難度成正比關(guān)系。心率變異性功率譜密度、腦電負(fù)荷水平等生理指標(biāo)呈現(xiàn)顯著性差異,呼吸頻率也有一定的變化,呼吸幅度和皮電的指標(biāo)變化不明顯。研究成果可用于夜間環(huán)境下的道路交通安全評(píng)價(jià)。
[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.
