Pre-collision System Benefit Estimation Method Based on Rear-End Collisions Generated by ASSTREET
Published October 12, 2011 by Society of Automotive Engineers of Japan in Japan
A novel method is proposed to estimate the benefits of active safety systems. The method is applied to a PCS (Pre-collision system) as an example to show its process and its benefits. A virtual traffic flow simulating actual traffic is firstly created by ASSTREET, and then the system benefits are measured for virtual collisions generated in the flow that represents actual rear-end collisions. The advantage of the method is that a mass of collisions enables to evaluate the system specification differences quantitatively and clearly points out the region that the systems are expected to work effectively.
