Sleep inertia in automated driving: Post-sleep take-over and driving performance

Sleep is emerging as a new driver state in automated driving. Post-sleep performance impairments due to sleep inertia, the transitional phase from wakefulness that can take up 30 min, are potential safety issue. Take-over immediately after impaired and drivers perceive take-over critical. The aim of presented study was assess behavior driving during 10 min sleep. A with N = 31 conducted high-fidelity simulator. were assessed a) under alert baseline conditions b) awakening electroencephalography-confirmed stable 15 s resulting more errors compared baseline. Lane keeping dramatically first 3 recovered rapidly. Drivers drove slower speed less for at least min. results suggest human-machine interaction design should account drivers’ post-sleep performance.
