Abstract: A driving simulator study was completed in order to examine drivers| level of trust and the type of Conceptual Model (CM) they held of an Adaptive Cruise Control system (ACC). Fifteen drivers participated in a ten days study where they were allocated to varying percentage of ACC reliability conditions (100%, 50%, 0%). Results demonstrated inappropriate levels of self-reported trust in relation to the corresponding level of reliability. In addition the DCMs were consolidated over a short period of time, but they did not match that of designers| model of ACC, thus better design solutions may be warranted.

Keywords: adaptive cruise control; ACC reliability; driver trust; conceptual models; longitudinal study; driving simulation; human factors; vehicle design; vehicle control.
