摘　　要：目前,国内在车载信息显示中文标准上存在部分空缺,有3个相关安全标准需要探索和建立:(1)驾驶员在座舱中能够阅读的最小字符高度;(2)驾驶员在单次信息提示中能接受的最多字数;(3)驾驶员在完成一次驾驶次任务时所能阅读的字数总和。制定了128人次的试验设计方案,搭建了试验间并完成了3类试验,试验结论为:(1)车载文字最小字符高度视线夹角不小于16′;(2)车载文字单次消息提示不超过12个字;(3)完成单次任务消息提示总量不超过30个字。In the in-vehicle simplified Chinese display standards,3 safety related questions need to be explored and established:(1)The minimum character’s height that drivers can read on in-vehicle screens;(2)The maximum number of characters that drivers can accept in a single information prompt;(3)The total number of characters that drivers can read when completing one non-driving task.Based on 3 types of experiments on a test bench through a 128-person withinsubject design,results suggest:(1)The automobile cockpits information display should use a minimum simplified Chinese character font height no less than 16’arc minutes;(2)A single message prompt in automobile cockpits contain no more than 12 characters;(3)The total characters for messages in a single non-driving task no more than 30 characters.
