It has been acknowledged that the applications of Articulated Steer vehicles (ASVs) result in some problems, such as rollover, jackknifing and snaking. In this book, for a typical ASV, a comprehensive study of the causes of the snaking, and of the effects of the vehicle parameters and operating conditions on the stability is presented. Furthermore, to stabilize the vehicle during its most critical driving conditions, some studies are directed towards designing different types of active stability control systems. The subject of this book fits well into the scope of Vehicle Dynamics and Control. The main interest of this work is in the development of elegant design procedures where advanced control theory results are combined with established vehicle dynamic modeling techniques, to come up with appropriate vehicle stability controllers. The contents of this book can be used as a guide to solving the development problems of all kinds of road vehicles in the areas of stability and control. More specifically, this book can significantly assist professionals of various industries and academia in the field of articulated vehicle design, in finding proper solutions to the stability problems.
