Résumé
A conventional Engine Control Unit (ECU) consists of two levels, called powertrain and engine levels. Historically, the design of this device is based on an organic approach. Thus, developments concerning gasoline and diesel control are today decoupled. Based on a functional approach, the aim of this thesis is to propose a generic architecture and a cross level consistency that could be used with diesel, gasoline or hybrid structures, this reduces costs and design time. Achieving this aim, we propose a new ECU hierarchical architecture consistent with control schemes and based on optimal and predictive/preview control. Moreover, we consider a simplified torque and cruise control problems to illustrate the feasibility and the relevance of the proposition.
