摘要:

为了研究全触屏人机交互界面(HMI)对驾驶风险的潜在影响,搭建了全触屏与非全触屏HMI的2种真实道路驾驶试验平台;在80、100 km/h的2种速度下,在使用不同HMI完成相同次级任务过程中,采集并分析了驾驶人的视线转移和手部转移的数据。结果表明:完成开空调、调风量、吹前风挡玻璃这些次级任务,相比传统模式,使用全触屏时驾驶人注视中控平台的总时间分别增加19.8 %、102.5 %、39.1 %;注视中控平台所需总时间与完成次级任务所需操作次数之间,呈现出指数增长关系;当使用全触屏执行操作次数大于3.5次的任务时,驾驶人每次操作会花费更多的注视时间。该研究结果为全触屏HMI的分心评测提供借鉴方法。

Abstract:

Two real road driving experimental platforms, the one with full-touch-screen Human-Machine Interface (HMI) and the other with non-full touch-screen HMI, were established to analyze the potential impact of an HMI mode with full-touch-screen on driving risk. And collected and analyzed the data on driver’s sight transfer and on hand transfer during drivers completing the same secondary task using different HMI. The results show that the total time of staring at the central control platform increases by 19.8%, 102.5%, and 39.1% compared to the traditional mode respectively, when using a full-touch-screen to perform secondary tasks such as turning on the air conditioning, adjusting the air volume, and blowing the front windshield; There is an exponential increasing relationship between the total time required to focus on the central control platform and the operation number required to complete the secondary tasks; Drivers spend more gaze time on each operation when using a full-touch-screen to perform the secondary tasks with more than 3.5 operations. These results provide a reference for the distraction evaluation of full-touch-screen HMI.

Key words: vehicle active safety, driving safety, driving distraction, human-machine interface (HMI), full touch screen, visual load
