This study examined the effects of formalized training on driver behavior and understanding of an adaptive cruise control (ACC) system with drivers experienced with ACC. Sixteen participants drove an ACC-equipped vehicle while following a lead vehicle around a test track. Participants completed three laps, each involving different lead vehicle behaviors, such as making a lane change or stopping at a red light, that test the limitations and capabilities of ACC (i.e., boundary conditions) of the subject ACC system. Immediately before driving, half of the participants watched a training video describing how the ACC system would respond to these lead vehicle behaviors. Participants’ knowledge of the ACC system limitations was assessed by a pre- and post-test questionnaire, and participants’ interactions with the ACC system - including braking behavior, other pedal movements, and actuation of ACC via steering wheel controls - were recorded by video cameras.
