A new book from SAE International provides a broad and comprehensive look at the technologies and advancements of one of the possible solutions for such challenges - hybrid powertrains for commercial vehicles.


This book was written for vehicle and component engineers and developers, researchers, students, policymakers, and business executives in the commercial vehicle and transportation industries to help them understand the fundamentals of hybrid powertrain technologies and market requirements for commercial vehicles. It is useful for anyone who designs or is interested in hybrid powertrains and their key components.

"Advanced Hybrid Powertrains for Commercial Vehicles" begins with the fundamentals of hybrid powertrain systems, government regulations, and driving cycles, then provides design guidelines and key components of hybrid powertrains for commercial vehicles. The term 'commercial vehicle' applies to everything from light delivery vehicles to class 8 long-haul trucks, buses, and coaches. Such vehicles are used for a wide range of duties, including transporting goods or people and infrastructure service.

Individual chapters of the book cover:

- Introduction of Hybrid Powertrains for Commercial Vehicles
- Internal Combustion Engines for Commercial Vehicles
- Introduction of Clutches and Transmissions for Commercial Vehicles
- Energy Storage Systems: Battery, Ultracapacitor, Accumulator, and Flywheel
- Hybrid System Design and Optimization
