The Influence of Risk on Driver's Trust in Semi-Autonomous Driving

Autonomous driving systems (ADS) in autonomous and semi-autonomous vehicles have the potential to improve driving safety and enable drivers to perform non-driving tasks concurrently. Drivers sometimes fail to fully leverage a vehicle’s autonomy because of a lack of trust. To address this issue, the present study examined the influence of risk on drivers’ trust. Subject tests were conducted to evaluate the effects of combined internal and external risk, where participants drove a simulated semi-autonomous vehicle and completed a secondary task at the same time. Results of this study are expected to provide new insights into promoting trust and acceptance of autonomy in both military and civilian settings.Automotive Research Center (ARC) at the University of Michigan, with funding from government contract DoD-DoA W56HZV-14-2- 0001 through the US Army Tank Automotive Research, Development, and Engineering Center.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/144567/1/98_Peterson_Luke-Final.pd
