Control and validation of expert tasks for a collision avoidance system

In order to improve car driving security, there have been a lot of developments by car constructors: air bag, seat belt. All of them are made to reduce human physical damage in case of accident but do not prevent the accident from taking place. We describe our work which forms part of the European project Prometheus which aims to propose a real time collision avoidance system embedded in a car. In this paper we discuss particularly the decision module which warns the driver against an eventual collision. For this we have chosen to use an expert system.
