Abstract:
This paper describes a validation study of evaluation metrics of driver states while using an automated driving system and driving behaviors after the transition to manual driving. We conducted a driving simulator experiment with 28 participants and a test course experiment with 13 participants. In both experiments, we used a mind-off-road state as the driver condition in the automated system, which was controlled using a cognitively loaded non-driving related task (N-back task). After the driver received a RtI (Request to Intervene) and the automated system terminated automatically, the driver had to change lanes to avoid an obstacle car that appeared in front of the participant’s vehicle. We measured cognitive and behavioral indices before and after the RtI. The results indicated that saccadic eye movements and blinking frequency were sensitive to the level of the driver’s cognitive load. The range of saccades was different in the two experimental conditions. The driving behavior results implied that drivers changed lanes closer to the obstacle car when they were loaded cognitively in automated driving. This later avoidance was found in both the driving simulator and test course experiments, but the margins to the obstacle differed in the virtual and real environments.
