Résumé -Comparaison de deux stratégies temps réel prédictives pour la gestion d'énergie optimale d'un véhicule électrique hybride -La présence d'au moins deux sources de puissance alternatives dans un véhicule électrique hybride pose le problème de la détermination du partage de puissance entre celles-ci. Le partage optimal tient compte de la demande du conducteur et mène à une consommation de carburant minimale. Cet article présente deux stratégies qui donnent une solution à ce problème d'optimisation en utilisant des informations prédictives concernant les conditions de la voie dans un horizon temporel futur limité. Les aspects importants en ce qui concerne l'optimalité du partage de puissance déterminé et l'applicabilité en temps réel des algorithmes sont aussi abordés.
Abstract -Comparison of Two Real-Time Predictive Strategies for the Optimal Energy Management of a Hybrid Electric Vehicle -The presence of at least two alternative power sources in a HEVposes the problem of determining the optimal power split among them for a given driver's request in order to achieve a minimum fuel consumption. This article will introduce two strategies capable of solving this optimisation problem both relying on predictive information about the driving conditions within a limited future time horizon. The important aspects of optimality of the determined power split and the real-time applicability of the algorithms are addressed.

This paper focuses on the possibilities of a Petri net based rapid control prototyping (RCP) tool chain. P/T nets extended by interfaces and connected to an extended state model allow the description of typical programmable logic controller tasks. After a general introduction to RCP, the method is applied to the area of sequential control, and code generation for the chosen model is depicted. The paper closes with an example for a tool chain, demonstrated by system simulation and Software-in-the-Loop for a subsystem of a flexible manufacturing system in an industrial fieldbus environment.
