Safety Evaluation of Autonomous Driving Intelligence System Equipped with Risk Predictive Brake Control and Head Up Display for Information Presentation

Abstract

Recently, traffic accidents including elderly drivers are increasing due to the aging society. This is related to a decline in driving ability of elderly drivers. Therefore, this research aims to develop a drive assistance function which can compensate the declined driving performance of elderly drivers. In the related researches, a driving assistance system with risk predictive brake control using the potential field method was constructed-: it assumes scenes where pedestrians might dart out from blind areas of occlusion. In this research, the Field Operational Test in public roads using a prototype vehicle is conducted, and the safety of the proposed autonomous driving intelligence system is evaluated by focusing on the velocity profile. As a result, driving safety can be enhanced by an autonomous driving intelligence system with risk predictive brake control and the risk information presentation of Head Up Display (HUD).
