This study focuses on the improved range of perception of drivers, who make use of Night Vision systems with pedestrian detection. It examines different objective and subjective appraisals of a Night Vision system with pedestrian detection with a focus on the drivers range of vision and drivers' distraction. Methods and results of test drives with 39 test persons are described for the assessment of driver behavior in interacting with different Night Vision systems which inform drivers about the presence of pedestrians. Data of driver eye movements was analyzed to evaluate the different HMI designs of pedestrian alerts, in a passenger vehicle with Head-up-Display (HUD), regarding the ergonomic suitability and safety benefit. All systems were compared in field tests on public roads and on a test track. The examined systems try to decrease the high rates of pedestrian injuries through visual assistance. The results show that vehicles equipped with appropriate HMI implementations of Night Vision systems, which inform the drivers about the presence of pedestrians, can improve range of vision, therefore increase safety compared to non Night Vision vehicles. Night Vision systems with pedestrian detection can also be superior to conventional Night Vision systems (baseline 2) regarding drivers perception when using an appropriate HMI design. The evaluated System B was superior in most analyzed parameters. One of the features of system B is the temporary character of the information, which is presented to the driver. With an appropriate HMI design, Night Vision with pedestrian detection increases perception of pedestrians in darkness. This is a contribution to increased road safety. Furthermore, there was no indication for increased driver distraction with an appropriate HMI design.
