全触屏车机系统和智能手机导航模式下驾驶人注视特性和车辆横向偏移
Driver gazing characteristics and vehicle lateral offset under two navigation modes of full-touch screen vehicle infotainment system and smart phone
摘要
Abstract
To investigate the difference in driver gazing characteristics and vehicle lateral offset under two navigation modes of full-touch screen vehicle infotainment system and smart phone,the driving data acquisition platform was constructed under two types of real-road conditions.The relevant data of 27 drivers and vehicles were collected under the two navigation modes of full-touch screen vehicle infotainment system and smart phone.Five indicators of total task duration,single time of looking away from front,number of gazing switches,total time of looking away from front and standard deviation of lane position were selected.Mean comparison,variance and significance analysis were carried out on 1 041 sets of valid data of the five indicators at the four vehicle speeds.The results show that at the four vehicle speeds,for the full-touch screen vehicle infotainment system navigation,the average values of four indicators of total task duration,number of gazing switches,total time of looking away from front and standard deviation of lane position are all higher than those of mobile navigation.Compared with mobile navigation,the average values of total task duration,number of gazing switches and total time of looking away from front are increased by respective 78.55％,77.17％ and 49.20％,while the average value of single time of looking away from front is decreased by 15.98％.With the increasing of vehicle speed,the total task duration,single time of looking away from front and total time of looking away from front under both navigation modes show a certain downward trend,while the standard deviation of lane position shows an obviously upward trend.Based on the analysis results of the above indicators,compared with the mobile navigation mode,the full-touch screen vehicle infotainment system navigation mode causes greater operational risks during the navigation setting stage.关键词
