Kartläggning av brister i överlämning av kontroll från förarstödssystem till bilförare

Investigation of deficiency in hand-over of control between Driver Assistance Systems and the driver

Automation is increasingly part of everyday driving, even if today’s driver assistance systems are not perfect and their deficiencies might lead to unexpected negative effects for road safety. In simulator studies Nilsson (1996) and Stanton, Young and McCaulder (1997), it was found that several drivers failed to reclaim control from the ACC system and crashed into the vehicle in front. These studies demonstrate the importance to study the issue of hand-over of control between the driver and driver support systems. An important research question is how the limitations of ADASs are communicated to the driver to help him/her to take over control of the vehicle in due time when the system cannot cope with the situation. Results from our survey with Volvo XC60 owners indicate that situations where drivers reclaim control include some not mentioned in the manual. Thirty-one respondents also reported mode errors, and one was initially not aware the system was an adaptive cruise control. Suggestions of future research focuses on whose responsibility it is to make the driver aware of system operational range and functionality; present ways of learning how to use the ACC may not be enough. It is in the society´s interest that systems coming out on the market do not bring about negative effects on safety. The aim of this project is to investigate: - What information does the driver need in order to reclaim control from the system? - How this information should be communicated most appropriately? - How society regulates and should regulate the introduction of new in-vehicle systems for driver assistance?
