Abstract

In this paper we introduce a new collision warning system which permits to warn the driver with sufficient anticipation about some inter-vehicular distance danger. The warning system is based on the future predictions from a 5-DOF (Degree Of Freedom) vehicle dynamics. The future inter-distance and the future relative velocity are compared with respect to certain safe conditions which are calculated from a dynamic inter-distance reference model. Some simulations withreal measure data illustrate the behavior of the proposed driver assistance system. This work has been financed by the ARCOS French Program, see http://www.arcos2004.com
