Abstract

Our previous paper proposed a deceleration for collision avoidance (DCA) as an index to evaluate the collision risk against a forward obstacle. In order to reduce the calculation amount, the calculation process of the DCA assumed that the following vehicle performed an uniform motion within a constant reaction time. However, the assumption would yield underestimation of the collision risk when the following vehicle accelerates and overestimation when it decelerates. Therefore, in this manuscript, the DCA was calculated on the assumption that the following vehicle kept the uniformly-accelerated motion within the reaction time and the numerical simulation was performed to show that the improved DCA could evaluate the collision risk properly compared to the conventional DCA.
