Straight motion of road vehicles

Mostrar otras versiones (2)

This book explores the straight motion of road vehicles with particular focus on the role played by tires, vehicle suspensions, and road cross slope. The authors consider vehicles currently in production as well as automated vehicles, which are likely to become more prevalent in the future. This wor...
