【摘要】 为了研究道路条件对驾驶紧张程度的影响,选择了33名驾驶员,选用驾驶员心率、眼球移动角速度和注视点分布范围3项测试指标,进行了多车型多工况实车试验。采用心电测试仪和眼动仪采集了3项测试指标试验数据,并进行回归分析,建立了不同车型的驾驶员测试指标隶属于不紧张区域、较紧张区域和很紧张区域的隶属度函数。在车速为80km.h-1,侧向余宽为1.2m的行车工况下,计算了各车型测试指标的隶属度。试验结果表明:大型车驾驶员3项测试指标的隶属度均属于较紧张区域,中型车驾驶员3项测试指标的隶属度均属于不紧张区域,与实车试验的驾驶员感受评价相符合。更多还原

【Abstract】 In order to study the effect of road condition on diver’s tensity, the test indexes including heart rate, moving speed of eyeball and gazing area were chosen. Through multi-condition and multi-type-vehicle tests with 33 drivers, the data of the indexes from electrocardiograph and eye tracker were collected and analyzed,the membership functions were established to evaluate the degrees that the indexes belonged to no tension area, some extent tension area and great tension area. On the condition that vehicle speed was 80 km·h-1 and lateral clearance was 1.2 m, the membership degrees of heavy-vehicle drivers were calculated. Experiment result shows that the membership degrees of large-vehicle drivers belong to some extent tension area, the membership degrees of medium-vehicle drivers belong to great tension area, which is consistent to the drivers’ safety perception of practical road-vehicle test. 5 tabs, 11 refs.更多还原
