Résumé / Abstract
Introducing Advanced Driver Assistance Systems (ADAS) into the vehicle could improve drivers' comfort and reduce road crashes. However, suitable methods are required to study driver/system interactions. In fact, ADAS generate critical use cases, i.e. situations where alarms, or absence of alarms, can be negative for safety. The present study aimed at evaluating the impact of being familiar with critical use cases created by the Forward Collision Warning (FCW) on driving simulator. We hypothesized that experiencing the system's function in critical situations would improve drivers' performance and their trust in the FCW. We compared judgments and driving performance of three independent groups: a 'control group' where drivers did not use the FCW, an 'unfamiliarized group' where drivers used the FCW without have been familiar with the system, and a 'familiarized group' where drivers used the FCW after have been familiar. Results showed that familiarization made drivers/system interactions more effective and safer. Moreover, familiarized drivers rated the system more positively than unfamiliarized drivers. However, familiarization decreased drivers' self-confidence and did not prevent from precipitance when overtaking slow vehicles. We discussed the relevance to using driving simulator in FCW's studies and the possibility to transfer skills and knowledge to field operational test. Finally, we proposed improvement to make familiarization with the system more effective.
