Abstract [en]

This study explored how failures related to an adaptive cruise control (ACC) were handled by drivers and what the effects on safety can be. The experimental study included forty-eight subjects and was performed in a moving base driving simulator equipped with an ACC. Each subject experienced two different failures in separate scenarios. In total, the study included four different failures, i.e., Unwanted acceleration, Complete lack of deceleration, Partial lack of deceleration, and Speed limit violation. The outcome of each failure scenario has been categorized based on whether the driver managed to avoid a collision or not. For the outcomes where collisions were successfully avoided, the situations were analyzed in more detail and classified according to the strategy used by the driver. Besides showing that partial lack of deceleration caused more collisions than complete lack of deceleration (43% compared to 14% of the participants colliding), the results also indicate a preference among drivers to steer and change lane rather than to apply the brakes when faced with acceleration and deceleration failures. A trade off relationship was identified between allowing a failing ACC to stay operational and on the other hand disabling it when an error is detected. Keeping the system operational can cause confusion about the mode of the system but as the results of the study indicate it can also improve the situation by reducing impact speed.

Abstract [en]

Drivers’ interactions with advanced driver assistance systems based on experiences from real driving and results from driving in a driving simulator were under investigation in this thesis. Questions posed were: - How do drivers perceive and interact with ADAS? - How are (technical) failures handled by drivers, and which are the consequences’ of these failures? - Which are the implications for diagnosis and detection of failures, as well as for system development? Special attention was given to driver behavior in response to technical failures in an adaptive cruise control system. The results are based on two studies, adopting an approach with a combination of qualitative and quantitative data. In study I focus group interviews were conducted and in study II a driving simulator experiment was conducted. The findings include notions on behavioral adaptations and monitoring inefficiencies for drivers facing failures. Implications for design, failure detection, and traffic safety are discussed. With regard to human- machine-interaction it is concluded that ADAS have effects on driver’s behavior, that these effects are individual and based on experience, and that measures towards failure containment should be a taken.
