THEORY OF GROUND VEHICLES

A leading and authoritative text for advancing ground vehicle mobility

Theory of Ground Vehicles, Fifth Edition presents updated and expanded coverage of the critical factors affecting the performance, handling, and ride essential to the development and design of road and off-road vehicles.

Replacing internal combustion engines with zero-emission powerplants in ground vehicles to eliminate greenhouse gas emissions for curbing climate change has received worldwide attention by both the vehicle industry and governmental agencies. To enhance safety, traffic flow, and operating efficiency of road transport, automated driving systems have been under active development. With growing interest in the exploration of the Moon, Mars, and beyond, research in terramechanics for guiding the development of extraterrestrial rovers has been intensified. In this new edition, these and other topics of interest in the field of ground vehicle technology are explored, and technical data are updated. New features of this edition include:

  • Expanded coverage of the fundamentals of electric drives, hybrid electric drives, and fuel cell technology
  • Introduction to the classification and operating principles of the automated driving system and cooperative driving automation
  • Applications of terramechanics to guiding the development of extraterrestrial rovers
  • Elaboration on the approach to achieving the optimal operating efficiency of all-wheel drive off-road vehicles
  • Introduction to updated ISO Standards for evaluating vehicle ride

An updated and comprehensive text and reference for both the educational and professional communities, Theory of Ground Vehicles, Fifth Edition will prove invaluable to aspiring and practicing engineers seeking to solve real-world road and off-road vehicle mobility problems.
