Hybrids vehicles have a long history and a promising future and Belgium is part of it. They have a very large variety of architectures and technical options. Each one with very different results depending not only the physical disposition but also the energy management policy. The characteristics of different architectures and its specificities have been studied in this work, focusing in the series-parallel configuration known as AutoMixte.
Buses, as a particular kind of vehicle, have specific requirements. The utilization of hybrid powertrains in buses is a very interesting way to reduce the pollution and the congestion in the cities at the same time, with very low investments in infrastructure and reducing the fuel consumption and the fuel-dependency of the town.
Planetary gears are widely used in vehicles. In addition to the differential gear, they are one of the main components of automatic gearboxes, accumulating key advantages like longer life span and higher compactness for relatively higher ratios. The design established the optimum speed ratio as an adaptation of the speed range of the power machines to the bus speed range. The complete design respected particular compatibility rules and verified the loaded resistance using commercial software and classic formulas from international standards.
The integration of the planetary gears was modelled in a global system model with all the powertrain elements in order to obtain the total maximum mechanical output of the bus. The verification of the performance of the vehicle includes a gradeability and an acceleration simulation.
This work ends with the simulation of the consumption of this powertrain in the bus assuming one particular energy management policy and the standardised test for buses know as SORT. The efficiencies of the electrical machines were taken into account as well as the charging and discharging efficiencies of the battery. Specific consumption maps of the engine were used to calculate the fuel consumption of the bus.

With the ever-increasing worldwide demand for energy, and the looming crisis in petroleum supplies, energy storage is emerging as an important area of research. Due to ever increasing concerns on energy conservation and environmental protection, the hybrid vehicle (HV) is a widely accepted interim solution for evolving from the conventional internal combustion engine (ICE) vehicle to the clean electrified vehicle. This book discusses new developments, energy management and emerging technologies of hybrid vehicles and hybrid electric vehicles.

This book on hybrid electric vehicles brings out six chapters on some of the research activities through the wide range of current issues on hybrid electric vehicles. The first section deals with two interesting applications of HEVs, namely, urban buses and heavy duty working machines. The second one groups papers related to the optimization of the electricity flows in a hybrid electric vehicle, starting from the optimization of recharge in PHEVs through advance storage systems, new motor technologies, and integrated starter-alternator technologies. A comprehensive analysis of the technologies used in HEVs is beyond the aim of the book. However, the content of this volume can be useful to scientists and students to broaden their knowledge of technologies and application of hybrid electric vehicles.
