【摘要】：分心駕駛是威脅交通安全的重要因素之一，造成駕駛員分心的因素很多，其本質(zhì)是這些分心因素產(chǎn)生腦負荷，進而影響駕駛動作，導(dǎo)致駕駛行為改變。駕駛行為改變最直觀表現(xiàn)就是由駕駛動作構(gòu)成的駕駛執(zhí)行過程的變化。因此從駕駛動作入手，研究不同腦負荷下的駕駛執(zhí)行過程動作量化分析十分必要。 首先，文章在回顧駕駛行為研究的基礎(chǔ)上，對駕駛執(zhí)行過程進行研究，包括研究基礎(chǔ)，研究方法以及研究內(nèi)容等,為本研究提供理論基礎(chǔ)。其次，根據(jù)駕駛動作研究的特殊性選定了合適的駕駛動作捕捉設(shè)備，根據(jù)實驗?zāi)康脑O(shè)計具有差異性的腦負荷實驗，完成了駕駛動作數(shù)據(jù)采集。最后，經(jīng)過對數(shù)據(jù)的預(yù)處理后，從駕駛動作參數(shù)和駕駛動作配合兩方面對量化的數(shù)據(jù)進行分析研究，實現(xiàn)了從定量角度研究不同腦負荷對駕駛執(zhí)行過程動作的影響。文章在駕駛動作參數(shù)分析中，主要采用了四種分析方法，即時間分析、波動性分析、動態(tài)時間規(guī)整（DTW）分析、以及頻域分析。通過這四種方法分別研究了腦負荷對駕駛執(zhí)行過程時間、駕駛動作幅度變化、動作之間差應(yīng)性以及動作連續(xù)性的影響。在駕駛動作配合分析中，，采用了動作時間及順序分析以及動作構(gòu)成分析方法，通過這兩種方法研究了腦負荷對駕駛動作的發(fā)生順序、持續(xù)時間、動作類型以及發(fā)生次數(shù)的影響。 通過本課題研究，不僅豐富了駕駛行為研究的方法，對全面地研究駕駛行為具有一定的理論意義；同時，建立了針對駕駛動作的量化分析處理方法，對未來駕駛執(zhí)行過程的研究具有一定指導(dǎo)意義。
[Abstract]:Distraction driving is one of the important factors threatening traffic safety. There are many factors that cause drivers to be distracted. The essence of distraction factors is that these distractions produce brain load, and then affect driving behavior and lead to the change of driving behavior. The most direct manifestation of driving behavior change is the change of driving process composed of driving movements. Therefore, it is necessary to study the quantitative analysis of driving action under different brain loads. Firstly, on the basis of reviewing the study of driving behavior, this paper studies the driving process, including the research basis, research methods and research contents, which provides a theoretical basis for this study. Secondly, according to the particularity of driving action research, the appropriate driving motion capture equipment is selected. According to the experimental purpose, the different brain load experiment is designed, and the driving action data collection is completed. Finally, after preprocessing the data, the quantitative data are analyzed and studied from two aspects: driving action parameters and driving movement coordination, and the effects of different brain loads on driving process actions are studied from the perspective of quantitative analysis. In this paper, four analytical methods are mainly used in the analysis of driving parameters, namely, time analysis, volatility analysis, dynamic time warping (DTW) analysis, and frequency domain analysis. The effects of brain load on the driving process time, the amplitude change of driving action, the difference between movements and the continuity of action were studied by the four methods. In the analysis of driving action coordination, the methods of action time and sequence analysis and motion composition analysis were used to study the influence of brain load on the sequence, duration, type and frequency of driving action. This research not only enriches the research methods of driving behavior, but also has certain theoretical significance for the comprehensive study of driving behavior. At the same time, the quantitative analysis and processing method for driving action is established. The research on the future driving execution process has certain guiding significance.
