Modélisation, conception et expérimentation d'un véhicule hybride léger pour usages urbains

Abstract : The exhaustion, increased cost and location of fossil fuels on the one hand, and the environmental problems caused by emissions of CO2 in the atmosphere on the other hand, are forcing many automotive manufactures to develop major research programs in the designof electric vehicles and hybrid electric. In this context, this thesis aims to test the feasibility ofan innovative hybrid drivetrain consisting of a vehicle from existing heat and reduce engine power while adding motors integrated into the wheels of the rear axle. This work was conducted as part of a project funded by ADEME and also in collaboration with the car manufacturer Aixam-MEGA.More specifically, the thesis has focused on the design of energy sources, energy modeling and functional vehicle and finally the implementation and experimental characterization of the vehicle.In the first chapter, the author develops a literature review on the existing hybrid electric vehicles. This allows then to introduce the innovative concept of hybrid drivetrain described above, based somewhat on a road coupling powers of thermal and electric propulsion.In the second chapter the author discusses the design of energy sources focusing on ultracapacitors. It offers an analytical approach simple calculation based on the tasks set by the manufacturer Aixam-MEGA. Modules selected ultracapacitors are then characterized experimentally (capacity, internal resistance, storage efficiency ...) taking into account the effect of temperature.The third and fourth chapters are devoted to the modeling of the vehicle. First, the third chapter discusses the modeling efficiency of the vehicle. The vehicle has been fully modeled using the formalism of Energetic Macroscopic Representation initially developed at the Laboratory of Electrical and Power Electronics of Lille. This model has led to the development of vehicle control. Then, in the fourth chapter, the author presents the functional modeling of the vehicle state machine. This allows predicting the behavior of the vehicle in its different life phases and defining the transitions between these phases. This stage of virtual prototyping is essential to verify the functionality of the upstream and vehicle safety.Finally, the fifth and final chapter is devoted to the experimental characterization of the vehicle. The different operations thermal, electric and hybrid are tested in real taxi trials.In conclusion, the thesis has led to the realization of a hybrid vehicle. The design approaches and modeling of sources and are validated, while also demonstrated the feasibility of a hybrid electric powertrain coupling the road.
