Abstract

Drivers learn to trust the systems in their vehicles and do not anticipate failures. The objective of this study was to investigate whether or not drivers can safely handle a vehicle when there is a sudden, unexpected shut down of power assisted steering. Forty drivers, ten in each of four vehicles, drove on a controlled road.

RESULTS indicated that the majority of drivers could not safely complete a low speed right turn when power assisted steering suddenly failed in a cornering scenario. Drivers viewed this as a dangerous safety issue and indicated that the risk of such a failure was unacceptable.

RESULTS highlight the importance of including real users in safety assessments to gain a more accurate understanding of the consequences of vehicle system failures. They also shed light on some potential challenges for automation failures on future vehicle systems.
