Advanced Hybrid Powertrains For Commercial Vehicles

Powertrains for commercial vehicles have evolved since the late nineteenth-century invention of the ICE. In the revised second edition of Advanced Hybrid Powertrains for Commercial Vehicles, the authors explore commercial powertrains through history from the ICE through the introduction of the hybrid powertrain in commercial vehicles. Readers are given an understanding of the ICE as well as the classification of commercial vehicle hybrid powertrains, the variety of energy storage systems, fuel-cell hybrid powertrain systems, and commercial vehicle electrification. The authors review the legislation of vehicle emissions and the regulation necessary to promote the production of fuel-efficient vehicles.

The aim of this work, consisting of 9 individual, self-contained booklets, is to describe commercial vehicle technology in a way that is clear, concise and illustrative. Compact and easy to understand, it provides an overview of the technology that goes into modern commercial vehicles. Starting from the customer's fundamental requirements, the characteristics and systems that define the design of the vehicles are presented knowledgeably in a series of articles, each of which can be read and studied on their own. This volume, "Alternative Powertrains and Supplements to the Conventional Powertrain", introduces alternatives and additions to the conventional powertrain of the commercial vehicle. The wide range of options is presented so as to be clearly understandable for those learning and working with them in a practical environment. Hybrid vehicles, electric powertrains and alternative fuels are discussed.

Hybrid Powered Vehicles, 2nd Edition builds on the original edition’s exploration of hybrid components, system engineering, design constraints, challenges, and opportunities of hybrid vehicles. Since the first edition was published in 2003, hybrid vehicles have seen major technical developments and have gained significant market share. This book provides the reader with a thorough yet accessible understanding of the latest hybrid technology developments, along with keen insight into the market forces shaping the technology and a look at what lies ahead. Author John German reviews the development history of hybrid vehicles and the current state of hybrid technology, including battery types and chemistries. He also highlights the cycles of fuel availability, fuel economy, and concern for environmental issues, and profiles government efforts to spur development of more efficient vehicles. Future enhancements, including more sophisticated hybrid control strategies and integrating additional electrical components to improve efficiency, are also featured. Cost reduction, being a major barrier to mass market adoption, is also discussed. Finally, future sales and market forecasts are offered, including the belief that hybrid sales will rapidly increase after approximately 2020 and will capture about 75% of the market by about 2030. Topics include: Transitional Technology or Ultimate Solution Design Components Design Constraints Plug-In Hybrid Design Hybrid System Optimization Customer Acceptance Future Development Future Conventional Hybrid and PHEV Markets

Collection of papers from the 2001 SAE World Congress, held March 5-8 in Detroit, Michigan. Papers highlight the latest worldwide hybrid-electric vehicle research and development. Papers cover vehicle systems analysis, modeling and testing, and electrical and engine hardware design and optimization.

The 34 technical papers in this collection focus on advanced hybrid vehicle powertrains and were presented at the Powertrain Electric Motors Sumposium on March 23, 2011. Topics covered include: design and development of a hybrid engine powered fuel efficient urban car; alternative plug in hybrid electric vehicle utility factors; on board jump start for belted alternator starter hybrids; weather, traffic and road condition impact on velocity profile using real world data; development of parallel hybrid system for RWD vehicle; and more.

Energy Efficiency of Vehicles educates readers about energy and the environment and the relationship between the energy we use and the environment. The world is at a point in time when people need to make very important decisions about energy in the next few decades. This book enables readers to utilize our scientific knowledge to make good rational decisions. Energy Efficiency of Vehicles provides information on: Calculations related to energy, power, and efficiency, and the impact of using different types of energy on the environment. Environmental consequences of consuming energy. Models related to impact of city driving on the energy efficiency and fuel economy of cars and trucks.

The internal combustion engine (ICE) vehicle has dominated the transportation market for nearly 100 years. Numerous concerns with continued use of fossil fuels arise, however, and these concerns have created an impetus to develop more efficient vehicles that release fewer emissions. There are several powertrain technologies that could supplant conventional ICEs as the dominant technology, most notably electric and hybrid powertrains. In order to achieve the levels of performance and cost of conventional powertrains, electric and hybrid powertrain designers must use design techniques and tools such as computer modelling, simulation and optimization. These tools facilitate development of a virtual prototype that allows the designer to rapidly see the effects of design modifications and precludes the need to manufacture multiple expensive physical prototypes. A comprehensive survey of the state of the art of commercialized hybrid vehicle powertrains is conducted, and the term multi-regime in ICE hybrid vehicle (ICEHV) modelling is introduced to describe designs that allow for multiple configurations and operating regimes. A dynamic mathematical model of a power-split architecture with two modes (or configurations) introduced by General Motors Corporation is developed and a steady-state version is programmed into the ADvanced VehIcle SimulatOR (ADVISOR) simulation software package. This ADVISOR model is applied to a commercial delivery vehicle, and the fuel consumption of the vehicle undergoing a variety of drive cycles is determined. The two-mode model is compared to the ADVISOR models for the Toyota Hybrid System (THS), parallel hybrid, and conventional powertrains in the same vehicle. The results show that for this vehicle type, the two-mode design achieves lower fuel consumption than the THS and conventional powertrains, and only slighter greater fuel consumption than the parallel hybrid design. There is also considerable potential for improvement in performance of.
