Pre-collision systems for urban environment accidents avoidance

Abstract

Primary security systems are oriented to avoid accidents, secondary, on the other hand, focus in reducing the consequences of them. There is a group of systems that stands halfway of both sets, they use information sources from first set, but usually they pursue the objectives of the second set, they are pre-collision systems. Pre-collision systems that were taken into account on this research work consider the actions to perform to control the vehicle (steering or breaking), and the generation of signals to deploy the security systems to be activated before the collision. In the present paper, a pre-collision system is presented, the system is able to avoid hits and collisions, or in the event of unavoidable accident, it minimizes the possible damage caused. The development of the mitigation maneuvers depends on the accurate analysis and the correct understanding of the environment. Following this statement, the present work provides obstacle detection, evaluation of risk and avoidance possibility.
