Impact of the driver’s visual engagement on situation awareness and takeover quality

During automated driving (SAE Level 3), drivers can delegate control of the vehicle and monitoring road to an system. They may then devote themselves tasks other than gradually lose situational awareness (SA). This could result in difficulty regaining when system requires it. In this simulator study, level SA was manipulated through time spent performing a non-driving task (NDRT), which alternated with phases where driver monitor scene, prior critical takeover request (TOR). The at TOR, visual behaviour after quality were analysed. results showed that just before TOR allowed development limited perception situation, only partially compensated for lack consolidated mental model situation. recovery, assessed number collisions, consistent SA. analysis engagement induced form perseverance consulting interface displayed, detriment checking mirrors. These underline importance helping restore good well advance TOR.
