摘　　要：车辆怠速起停系统的应用能有效降低油耗和尾气排放量。为探究驾驶人使用车辆怠速起停系统的行为意愿,调查受访者的社会经济属性及其对车辆怠速起停系统的主观态度特征,采用Likert量表设计行为意愿调查问卷,收集到520份有效样本。通过共同方法偏差检验、信度和效度检验,保证样本数据的稳定性和可靠性。在技术接受模型和计划行为理论的框架下,新增潜变量-驾驶人对怠速起停系统的信任,以优化适配指标来调整模型路径关系,建立该系统使用意愿的结构方程模型。通过路径假设检验和中介效应检验结果来梳理主观因素之间的作用关系,并依据社会经济特征划分群组,建立多群组模型分析个体差异对系统使用意愿的具体影响。结果表明:影响车辆怠速起停系统使用意愿的主观因素中,行为态度的影响作用最显著,信任和知觉行为控制的影响作用较显著,而感知有用性不是显著影响因素;感知易用性和主观规范对信任皆有显著正向作用,并通过信任影响使用意愿;高学历群组受感知易用性和信任的影响较大,年长组和小型车组受主观规范影响较大,而大型车组受知觉行为控制影响较大。The vehicle idle start-stop system can significantly reduce fuel consumption and exhaust emissions.This study examines drivers' socio-economic attributes and subjective attitudes towards vehicle idle start-stop system to investigate their usage intention.A questionnaire of behavioral intention is designed with the Likert scale,and 520 valid observations are collected.The stability and reliability of the sample data are examined using common method bias test,reliability,and validity test.Under the framework of the technology acceptance model and the theory of planned behavior,a new latent variable,i.e.,driver's trust in the idle start-stop system is added.The final structural equation model about usage intention of the system is established by optimizing the fitness value.From the tests of the model path hypotheses and mediation effect,the influence of each subjective factor is sorted out.Groups are di-vided according to socio-economic characteristics,and multiple-group models are established to analyze the specific influence of individual differences on the intention to use the system.The results found that:①the most significant factor affecting the intention of drivers to use the vehicle idle start-stop system is their behavioral attitude;②trust and perceived behavioral control also have a significant effect,while perceived usefulness is not a significant factor;③subjective norm and perceived ease of use have a significant positive effect on trust,which in turn affects the us-age intention;4)the higher-educated group is more likely to be influenced by perceived ease of use and trust,and the older and miniature-vehicle groups are more influenced by subjective norms while the oversized-vehicle group is more influenced by perceived behavioral control.
