Effects of non-driving related tasks during autonomous driving

Miroslava Horáková

The presented study deals with the topic of non-driving related tasks in the context of driving in autonomous mode. In the introduction, the levels of automation are defined and the pitfalls of the L3 level (third level of automation, conditional automation), are described, especially with regard to takeover performance. A takeover is defined both in terms of its speed and quality. The individual variables measured in this context are described. Subsequently, the concept of non-driving related tasks is described both in a broader context (manual driving) and in a narrower context (driving in autonomous mode). Non-driving related tasks have a negative effect on takeover performance, takeover time, incidence of collisions and time to collision (TTC). In this context, the time required to takeover the driving task s is discussed, which will enable a quality takeover. The types of activities in terms of their characteristics (sensory modality, cognitive demand, manual load etc.) vary in the degree they influence takeover performance. Visual, cognitively demanding, and manual activities have the greatest negative influence. The explanation for effects of non-driving related tasks s is then embedded in a theoretical framework in the form of the Wicken's Multiple Ressources Model.

Keywords: non-driving related task; autonomous driving; autonomous vehicle; levels of automation; takeover performance; takeover request; takeover time
