Driver Comprehension of Integrated Collision Avoidance System Alerts Presented through a Haptic Driver Seat

摘要: The purpose of this study was to quantify the effects increasing number collision avoidance system alerts presented through a haptic driver seat on drivers’ response performance. Twenty-four participants performed specific driving maneuvers in one, three, or seven while they drove an instrumented vehicle. Participants verbally identified after executing maneuver. Results show that drivers made correct maneuver alerts. This likely because strong stimulus- compatibility designed into seat. As predicted by Information Theory, mean manual time significantly increased, and their verbal accuracy degraded, as increased. A three-alert approach is recommended providing design requirements are met.
