Abstract

Other than during manual and partly automated driving, the driver will not need to constantly observe and correct the path of his/her car with future conditionally automated driving (CAD) systems. The driver will be only responsible to stay alert and be ready to take-over the driving in a preset handover time, if requested. The aim of this simulator study was to examine the reactions of drivers, when requested to take-over after a long, monotonous conditionally automated drive. The conditionally automated drives of 20 drivers (mean driving time of 2:51 ± 0:18 h) were evaluated. To test their reaction and take-over ability, the drivers experienced four easy take-over situations and were additionally challenged with a demanding situation in their worst state regarding fatigue. There was no significant influence found of their fatigue state on the take-over time and quality. The different take-over times in different situations point merely towards an adaption of the drivers' reactions onto the specific necessities of the different driving situations.
