Analysis of Physical Readiness for Take-Over in Automated Driving – Approach to Classify Non-Driving Related Activities According to Their Level of Complexity

Abstract

Take-overs are becoming part of the use of automated driving functions, since these functions will be limited to certain Operating Driving Domains at first. As the OEM must guarantee safe driving at all times, safe take-overs of the driver are also part of these driving functions. During automated driving in SAE Level 4 more postures and interior adjustments will be possible. This will make the evaluation and prediction of the take-over procedure more complex. In addition to the cognitive transition, the physical adaptation of the driver and the interior back to a drivable state must also be taken into account. In this work, three factors were identified that characterize non-driving related activities in physical terms: whether an item is used, whether the interior is adjusted and whether seat, steering wheel or pedals are adjusted. On this basis, four complexity levels were derived. By assigning an NDRA to a complexity level, the driver's effort for physical adaptation to the driving task and capability to take over can be derived.
