摘　　要：以大量的驾驶员心理生理实车试验和基于该实车试验数据所建立的回归模型为基础,利用数理统计和模糊数学理论方法,建立了心率计算指标、眼球移动角速度计算指标和注视点分布范围计算指标分别隶属于“不紧张”、“较紧张”和“很紧张”模糊集的隶属度函数.在此基础上,通过理论分析得出了上述三个“计算指标”和驾驶员行车紧张度的定量关系模型.应用该模型可以对“计算指标”相应的紧张度进行定量研究,从而为建立实际行车环境和紧张度的定量关系模型打下基础.Based on numerous driver＇s psychological and physiological experiments, a regression model is formed by the experiment data. According to mathematical statistics and fuzzy mathematics, the subordination function, which indicates three indices（heart rate, moving speed of eyeball and gazing area）belong to “no tension” set, “some extent tension” set and “great tension” set, is established. Lastly, the quantitative relation model between above calculating indexes and driver＇s tensity is found. It can be used to quantificationally study the tensity of the calculating indexes. This research lays a foundation to establish a quantitative relation model between actual traffic environment and driver＇s tensity.
