致驾驶疲劳因素联合作用的机理辨识

Driving work is mainly based on sensation and information of the roadway. It is valuable for traffic accident precaution and elimination to research driving fatigue factors such as information processing load, continuous driving load, background workload and driving fatigue mode identification. This project emphasizes all factors affecting driving fatigue; the interaction of all factors which may lead to driving fatigue; driving fatigue course, law and mechanism; effect on sorting of driving fatigue, assessment system on driving fatigue and test system; fatigue effect identification mode in dangerous; testing and assessment mode of driving fatigue. The driving feedback and selection mode is built, which starts refresh ideas on filtering out dangerous and high dangerous person mode. In the research, a set of simulation equipment is developed to examine the drivers' static and dynamic fatigue. Emphasizing on the driving fatigue effect pattern, the paper deeply research the driving fatigue' characters and its causing factors, bring forward that the information complexity, impulse effect and U effect, and also, analyze the continuity and scatter workload of the driving fatigue, which presents theoretical foundation for optimized matching design in people-vehicle-road system and traffic accidents prevention. Different driving fatigue function modes are established according to influences of multiple fatigue factors, the reliability theory are adopted to make fallibility analysis on driving fatigue, mutual action analysis on illegibility, random and interleaving of fatigue factors. Driving fatigue degree is a constant and integrated restrict condition, with the notable slack variables' characters. The evaluation system of driving fatigue is realized. The report systemically discussed the reliability principle and algorithm of the driving fatigue and the safe driving, quantization of driving fatigue factors, analysis and filtration of the driving fatigue's multi-factors, the index and the integrated evaluation of the driving fatigue and the multi-factor analysis and application of driving fatigue. The symbol of driving fatigue is multi-dimensions and multi-sides, and its explanation theory, test methods and control measurement require diversified research.
