摘要
作为新的技术和经济增长点,微型电子计算机、无线电通讯、卫星导航等新技术、新设备和新方法已开始广泛应用于汽车工业中,汽车的信息化进程正在逐步加速。但根据多资源理论,以显示查看和信息输入为主要形式的车载信息系统应用任务会分散驾驶员在行驶过程中最重要的视觉注意力,与主要驾驶任务在视觉和认知等多种有限资源形成竞争,从而影响驾驶安全。研究发现,车载信息系统使用任务造成的注视次数和注视时间与汽车的碰撞危险有直接关系,并降低了驾驶员对关键交通事件的探测识别能力和对车辆的控制能力。因此,车载信息系统在行车中的安全性设计非常重要,其研究要点包括人机交互方式、驾驶员行为特征等,研究方法则包括实际道路测试、仿真环境测试、简单实验室测试等。
As a fresh growth on technology and economy, new solutions of telematics, navigation, internet and entertainment while driving based on In-Vehicle Information System （IVIS） was applied widely in automobile industry recently. The process of automobileinformationization has been accelerated gradually. However, based on Multi-Resource Theory, the application of IVIS during driving in forms of display check and text input distracted drivers visually in certain degrees, which caused threats to driving safety by competing with major driving tasks on visual, cognitive and other resources. Previous research found that the glance frequency and duration from using IVIS related to crashes and traffic dangers directly, meanwhile, decreased driver＇s ability on detecting key road incidents and controlling vehicles. Thus the safety design of IVIS, which focused on human-machine interactive method and driver＇s behavioral character, was very important. General methodologies of such research include field test, simulation test and simple laboratory test.
