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

Résumé : In Driving, drivers must develop and maintain a good situation awareness [3, 5]. Situation awareness (SA) involves processing the available visual information (SA level 1: perception), developing an understanding of the situation (SA level 2: comprehension) and anticipating the future states of the environment (SA level 3: projection). However, the updating of SA may be discontinuous. According to Rockwell (1988) [6] drivers tend to not spend more than two seconds without taking information about the environment. When it comes to automated driving, especially when a non-driving task is allowed, Rockwell's 2-second rule does not apply. In level 3 automated vehicles (SAE level), Zeeb et al. (2015) [7] reported that the participants looked at the central console without interruption from 2s to 55 seconds during non-driving activities, which can significantly impair and SA. In addition, many studies highlighted a deterioration of take-over quality when performing a Non-Driving Task (NDT) [1, 2, 4, 8]. In the context of the development of the level 3 automated vehicles, it is essential to understand the extent to which a loss of SA can be detrimental, especially in the event of a critical takeover request.
