Collision Risk Evaluation Index Based on Deceleration for Collision Avoidance (Second Report)

- Forward obstacle collision warning system based on deceleration for collision avoidance -

Abstract

This paper proposes a method to provide a forward obstacle collision warning system (FOCWS) based on deceleration for collision avoidance (DCA) proposed in the first report. First, driving simulator experiments are performed to determine reaction time, which is an essential parameter for the calculation of the index. Next, we propose a new FOCWS that provides drivers with a real-time indicator of DCA as visual information in addition to a warning sound as auditory information. Driving simulator experiments are conducted to verify the effectiveness and acceptability of the proposed system.
