摘　　要：以车辆极限行驶工况为负性刺激,通过评价量表和现场访谈获取了12名受试者作为前排乘员在实车试验中的主观感受,并运用生理多导仪记录了皮肤电活动数据;通过对比经历刺激前后的数据并结合假设检验,分析了主观评价的变化。结果表明:在经历极限行驶工况刺激后,乘员对车辆控制能力的预期有显著提高,但对车辆决策意图不确定性的担忧加剧;将皮肤电导水平数据与试验过程中的事件信息相结合,能够反映乘员预期的变化。Taking the extreme driving conditions as negative stimulus,the subjective feelings of 12 subjects as front-seat passenger were obtained in the process of realvehicle testing by means of evaluation scale and interview,and the skin electrical activity data were recorded by the physical polygraph.On this basis,the change of the passengers’subjective evaluation was studied by comparing the data before and after experiencing the unintended vehicle maneuver and using the hypothesis testing method.The results show that the negative stimulus improves the passengers’expectation of vehicle control ability,but increases their anxiety about the uncertainty of vehicle decision-making intention.In addition,the combination of the data of skin conductance level and the data of the event during the test can reflect the change of passenger’s expectation.
