In this work, a short preview of traffic provided by on-board sensors is used to minimize fuel consumption in a parallel hybrid vehicle capable of controlling both the vehicle velocity and the torque-split ratio. A two-stage version of Pontryagin’s minimum principle was used, but some of the standard simplifying assumptions in reduced-order modelling of hybrid vehicles were avoided to ensure th...

New transportation systems have to be developed to face the increase of pollution and the depletion of petroleum resources. Hybrid Electric Vehicles (HEVs) and Electric Vehicles (EVs) are developed as short term solutions. MEGEVH is a French scientific network which aims to propose generic methodology for efficient energy management of different EVs and HEVs, independently of the kind of vehicl...

In this paper an optimal management of the energetic flows in a hybrid vehicle based on a Genetic Algorithm is introduced. The aim is maximize the use of the electric engine, minimizing the use of the internal combustion one, increasing the driving pleasure and reducing consumptions, emissions and noise. From the available literature, a typical configuration series-parallel hybrid engine as has...

Hybrid electric vehicles employ a hydraulic braking system and a regenerative braking system together to provide enhanced braking performance and energy regeneration. In this paper an integrated braking system is proposed for an electric hybrid vehicle that include a hydraulic braking system and a regenerative braking system which is functionally connected to an electric traction motor. In the ...

Hybrid Electric Vehicles (HEVs) are driven by two energy convertors, i.e., an Internal Combustion (IC) engine and an electric machine. To make powertrain of HEV as efficient as possible, proper management of the energy elements is essential. This task is completed by HEV controller, which splits power between the IC engine and Electric Motor (EM). In this paper, a Genetic-Fuzzy control strategy...

Hybrid electric vehicles with significant all-electric range provide a promising alternative to zero emission vehicles (ZEVs) without the problem of the limited range of electric vehicles. Ovonic nickel-metal hydride (NiMH) batteries feature a combination of high power and energy density ideal for ZEV-range hybrid electric vehicles. A series of high-power, highenergy batteries ranging in size f...

Fuzzy control strategy is developed for the dual-clutch single-axis torque coupling parallel hybrid electric vehicle. In this paper the torque distribution fuzzy controller which has been designed for the hybrid vehicle which is optimized by genetic algorithms. The simulation model of the hybrid vehicle was built upon matlab / simulink and ADVISOR software. Then a fuzzy rules and correspondent ...

Plug-in hybrid electric vehicles (PHEVs) are hybrid electric vehicles that can draw and store energy from an electric grid to supply propulsive energy for the vehicle. This simple functional change to the conventional hybrid electric vehicle allows a plug-in hybrid to displace petroleum energy with multi-source electrical energy. This has important and generally beneficial impacts on transporta...

We consider the problem of autonomously controlling a fixed-wing aerial vehicle to visit a neighborhood of a pre-defined waypoint, and when nearby it, loiter around it. To solve this problem, we propose a hybrid feedback control strategy that unites two state-feedback controllers: a global controller capable of steering or transitioning the vehicle to nearby the waypoint and a local controller ...
