"Left!" - "Right!" - "Follow!"

Abstract

Influencing factors on the take-over performance during conditionally automated driving are intensively researched these days. Most of the studies focus on visual and motoric reactions. Only limited information is available about what happens on the cognitive level during the transition from automated to manual driving. Thus, the aim of the study is to investigate a measurement method for assessing the cognitive take-over performance. In this method, the cognitive component decision-making is operationalized via concurrent verbalization of action decisions. The results suggest that valid predictions for the time of the decision can be provided. Additionally, it seems that the effects of situational complexity on the driver behavior can be extended to cognitive processes. A temporal classification of the decision-making within the take-over process is derived that can be applied for the development of cognitive plausible assistance systems.
