摘　　要：为研究使用车载信息装置对驾驶行为的影响,基于虚拟驾驶仿真平台,开展正常驾驶、操作按键式和触摸屏式收音机驾驶分心试验;应用外周视觉检测任务法（PDT）测量驾驶人反应时间、PDT目标命中率以及车速和跟驰距离等参数,以评估分心行为的心理资源需求及其对驾驶绩效的影响。试验结果表明：使用车载信息装置会降低驾驶人反应能力和驾驶绩效,操作触摸屏分心与操作按键分心相比,驾驶人反应时间延长了167 ms,PDT目标命中率降低了10%,速度保持和车距保持能力下降,使用触摸屏式车载信息装置需要更多的心理资源,对两侧视野内的信息刺激反应明显迟钝,对行车安全有较大影响。To investigate the influence of the use of in-vehicle information devices on driving behavior,driving distraction experiments were performed by using a virtual driving simulation platform,a key press type radio,and a touch panel radio among others. In order to evaluate psychological resources driving distraction demands and the impact on driving performance,the driver response time,the target hit rate,the vehicle speed variation and the car following distance were measured with PDT. The results show that the use of in-vehicle information device can decrease the driver＇s response capacity and driving performance,that for a given driver,the response time measured when he or she drives and makes use of the touch panel is 167 ms longer than that measured when he or she drives and makes use of the key-press type,and the PDT target hit rate is 10% lower,that the use of the touch panel also has a pronounced influence on the speed maintenance and car following maintenance capacity,and that the use of the vehicle information device with touch panel requires more psychological resources,and decreases reaction on both sides of the field of view of information stimulation,therefore the use of the touch panel has a significantly negative influence on the driving safety.
