Advanced Chassis Control Technology For Steer By Wire Vehicles

Advanced Chassis Control Technology for Steer-by-Wire Vehicles details state-of-the-art drive-by-wire technology, enabling engineers to create safer and smarter steering technology. With applications in Formula 1 driving, this book is an accessible yet ambitious introduction to the technology that is fast becoming the future of road vehicles. Steer-by-wire systems replace conventional mechanical technology with electronic sensors, controllers, and actuators, enhancing functionality when steering. Features such as variable steer ratio, customized road feel, and advanced vehicle dynamics control all ensure that this maximizes safety when driving. The book looks first at the theory behind this technology and compares it to conventional mechanical steering. It discusses control through forward and backward dynamics and a shared steering control concept to improve vehicle handling and performance, relevant to intelligent vehicles. It also explains how to create chassis domain fusion control, four independent wheels steering system and teleoperated control. Using case studies and ISOs, the book is a practical guide to safely designing steer-by-wire systems. The book is an essential guide to all engineers working in the modern automotive industry.

X-by-wire Unmanned Ground Vehicles (UGVs) have been attracting increased attention for various civilian or military applications. The x-by-wire techniques (drive-by-wire, steer-by-wire, and brake-by-wire techniques) provide the possibility of achieving novel vehicle design and advanced dynamics control, which can significantly improve the overall performance, maneuverability, and mobility of the UGVs. However, there are few full x-by-wire UGVs prototype models reported in the world. Therefore, there is no book that can fully describe the design, configuration, and dynamics control approach of full x-by-wire UGVs, which makes it difficult for readers to study this hot and interesting topic. In this book, we use a full x-by-wire UGV, developed by our group, as the example. This UGV is completely x-by-wire with four in-wheel motors driven and a four-wheel independent steer steer. In this book, the overall design of the UGV, the design of the key subsystems (battery pack system, in-wheel motor-driven system, independent steer system, remote and autonomous control system), and the dynamics control approach will be introduced in detail, and the experiment's results will be provided to validate the proposed dynamics control approach.

This book belongs to the field of intelligent vehicle control, which is dedicated to the research of nonlinear control problems of intelligent vehicle chassis-by-wire systems. Through the nonlinear stability control of the steer-by-wire system and the consistency optimization control of the brake-by-wire system, the performance of the vehicle subsystem is improved. Then, the decoupling control of the nonlinear inverse system is used to realize the decoupling of the chassis-by-wire system. Finally, this book further adopts nonlinear rollover prevention integrated control to improve the rollover prevention performance of the vehicle.

Featuring contributions from industry leaders in their respective fields, this volume presents comprehensive, authoritative coverage of all the major issues involved in road vehicle dynamic behavior. It begins with a short history of road and off-road vehicle dynamics followed by thorough, detailed state-of-the-art chapters on modeling, analysis and optimization in vehicle system dynamics, vehicle concepts and aerodynamics, pneumatic tires and contact wheel-road/off-road, modeling vehicle subsystems, vehicle dynamics and active safety, man-vehicle interaction, intelligent vehicle systems, and road accident reconstruction and passive safety.

This book focuses on the control-by-wire system, particularly the steer-by-wire system, as well as its control and optimization issues in chassis integration. The steering stability of the vehicle, handling portability, and overall performance of the chassis system are improved by steer-by-wire technology, which includes stability control, road-feeling control, decoupling control, force and displacement coordinated control, and chassis integration optimization. Furthermore, intelligent control goals such as active collision avoidance and active rollover prevention of the vehicle are realized, and the active safety of the vehicle is increased, due to the integrated control of the steer-by-wire system and chassis system. In this book, different types of steer-by-wire systems are introduced, as well as thorough force and displacement control strategies and their implementation in chassis integrated control, ensuring the intelligent and unmanned driving's control reaction speed and precision.

The AVEC symposium is a leading international conference in the fields of vehicle dynamics and advanced vehicle control, bringing together scientists and engineers from academia and automotive industry. The first symposium was held in 1992 in Yokohama, Japan. Since then, biennial AVEC symposia have been established internationally and have considerably contributed to the progress of technology in automotive research and development. In 2016 the 13th International Symposium on Advanced Vehicle Control (AVEC’16) was held in Munich, Germany, from 13th to 16th of September 2016. The symposium was hosted by the Munich University of Applied Sciences. AVEC’16 puts a special focus on automatic driving, autonomous driving functions and driver assist systems, integrated control of interacting control systems, controlled suspension systems, active wheel torque distribution, and vehicle state and parameter estimation. 132 papers were presented at the symposium and are published in these proceedings as full paper contributions. The papers review the latest research developments and practical applications in highly relevant areas of vehicle control, and may serve as a reference for researchers and engineers.
