Crossing collision prevention system using IVC and in-vehicle obstacle detection sensor

In this paper, a novel crossing collision prevention system is proposed. The on-board unit of the system shares own driving information (position, velocity etc.) and other vehicles´ driving information which is acquired by in-vehicle obstacle detection sensors with surrounding vehicles via inter-vehicle communication network. In a theoretical analysis, a T-junction is targeted as a road environment of the crossing collision prevention system and the safety performance of the proposed crossing collision prevention system (Fully Vehicle Information Acquiring Probability: FVIAP) is analyzed. The performance analysis to the penetration rate of on-board units indicates that the proposed system superiors to the conventional system which shares only in-vehicle driving information via inter-vehicle communication network. It means that the proposed system can attain equivalent FVIAP at a penetration rate lower than the conventional system. Furthermore, performance analysis to the sensing range is conducted and it indicates that the sensor for FVCWS based on the ISO15623 is enough for the in-vehicle detection sensor of the proposed system.
