Intelligent manoeuvring and execution control

In the framework of the European Prometheus Eureka project the authors´ work concerns the development of an intelligent copilot which assists the pilot in his driving tasks by giving soft and hard warnings. This paper deals with intelligent manoeuvring and execution control for cars on roads. It concerns the development of an interactive system for the execution control which monitors the car manoeuvres in order to maintain sufficient safety margins. The principle consists in hierarchically structuring the driving activities from strategical level (going from one place to another one) to manoeuvring level (speeding up). The key-point of the approach consists in attaching an execution control at each activity. This enables to react at a level as low as possible when environment changes. The proposed structure is composed of a real-time software in which a real-time expert system is integrated. The expert system allows to simply coordinate the set of monitoring tasks. A simulator is designed to reproduce the vehicle behaviors according to the situation in the traffic
