Abstract

This study examined drivers' responses to simulated autonomous technology failures in semi-autonomous vehicles. A population of 40 individuals was tested, considering the following independent variables: age of the driver, speed at disengagement, and time at which the disengagement occurred. Participants received auditory and visual warning at the time of disengagement and were asked to regain control of the vehicle while maneuvering within a S-curve turn. Participants' perception associated to the estimation of success of the control takeover, estimation of test duration, and estimation of the speed of travel showed poor accuracy. Speed recollection accuracy was lower for older participants, while younger participants showed overconfidence in the assessment of the quality of their control takeover. The employed human-machine interface highlighted concerns on the use of central console displays. Trust in the technology and nervousness to the possibility of a disengagement showed higher levels of anxiety for high speeds.
