Book Description
Vehicles are being equipped with more and more smart devices, which help the driver in his tasks. Alongside the trend to more and more autonomous vehicles emerges the possibility of making vehicles that move together as a platoon, which can be defined as a spatio-temporal organization of a set of vehicles based on a specific predetermined geometrical configuration. Basically, there are two main approaches for performing platoon control and these depend on the reference frame used (local or global). Even if the literature about platoon control is abundant, the most commonly used metrics are only tied to the stability of the platoon, that is, to the lateral and longitudinal distances between vehicles. However, these metrics are sufficient enough for a first evaluation of one algorithm; a deeper evaluation of a platoon control solution requires more well-defined metrics and perturbations that allow for the testing of algorithms with various parametrized conditions. The goal of this article is to present definitions of metrics, perturbations, spatial configurations, and scenarios that are aimed at helping scientists in the field to determine strong and precise evaluations of their platoon control algorithms. The work presented in this article stems directly from thinking performed during the institutional projects in which the authors have been involved and also takes inspiration from numerous articles on the subject and experiments made both in simulation and with real vehicles.

Book Description
Connected vehicle technology has the potential of drastically improving the safety and mobility of transportation system. Recognizing and identifying the vehicle platoons in a traffic stream has the potential of changing the arterial signal control logic and increasing the bandwidth of the signal coordination system. This thesis investigated the nature of traffic platoons and developed a platoon identification algorithm under the connected vehicle environment. In this thesis, definition and characteristics of vehicle platoons are investigated through past literature and simulation results. A real-time algorithm to identify vehicle platoons is developed based on the findings. The proposed algorithm is implemented and simulated using PTV VISSIM. Performance measures are identified and proposed based on past studies. Impacts of penetration ratio of connected vehicle on the proposed algorithm is also investigated. A similar platoon identification algorithm from the past research is also implemented in PTV VISSIM and evaluated. The evaluation result of the existing platoon identification algorithm is compared to that of the proposed algorithm. The proposed approach is found to be more robust and practical in platoon identification. The electronic version of this dissertation is accessible from http://hdl.handle.net/1969.1/155563

Book Description
CONNECTED VEHICULAR SYSTEMS A framework for the analysis and design of connected vehicle systems, featuring numerous simulations, experimental studies, and problem-solving approaches Connected Vehicular Systems synthesizes the research advances of the past decade to provide readers with practical tools to analyze and design all aspects of connected autonomous vehicle systems, addressing a series of major issues and challenges in autonomous connected vehicles and transportation systems, such as sensing, communication, control design, and command actuating. The text provides direct methodologies for solving important problems such as speed planning, cooperative adaptive cruise control, platooning, and string traffic flow stability, with numerous simulations and experimental studies for implementing algorithms and parameter settings. To help the reader better understand and implement the concepts discussed, the text includes a variety of worked examples, including those related to car following, vehicular platooning problem, string stability, cooperative adaptive cruise control, and vehicular communications. Written by two highly qualified academics with significant experience in the field, Connected Vehicular Systems includes information on: Varying communication ranges, interruptions, and topologies, along with controls for event-triggered communication Fault-tolerant and adaptive fault-tolerant controls with actuator saturation, input quantization, and dead-zone nonlinearity Prescribed performance concurrent controls, adaptive sliding mode controls, and speed planning for various scenarios, such as to reduce inter-vehicle spacing Control paradigms aimed at relaxing communications constraints and optimizing system performance Detailed algorithms and parameter settings that readers can implement in their own work to drive progress in the field Connected Vehicular Systems is an essential resource on the subject for mechanical and automotive engineers and researchers involved with the design and development of self-driving cars and intelligent transportation systems, along with graduate students in courses that cover vehicle controls within the context of control systems or vehicular systems engineering.

Book Description
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.

Book Description
Vehicle Dynamics and Control provides a comprehensive coverage of vehicle control systems and the dynamic models used in the development of these control systems. The control system applications covered in the book include cruise control, adaptive cruise control, ABS, automated lane keeping, automated highway systems, yaw stability control, engine control, passive, active and semi-active suspensions, tire-road friction coefficient estimation, rollover prevention, and hybrid electric vehicles. In developing the dynamic model for each application, an effort is made to both keep the model simple enough for control system design but at the same time rich enough to capture the essential features of the dynamics. A special effort has been made to explain the several different tire models commonly used in literature and to interpret them physically. In the second edition of the book, chapters on roll dynamics, rollover prevention and hybrid electric vehicles have been added, and the chapter on electronic stability control has been enhanced. The use of feedback control systems on automobiles is growing rapidly. This book is intended to serve as a useful resource to researchers who work on the development of such control systems, both in the automotive industry and at universities. The book can also serve as a textbook for a graduate level course on Vehicle Dynamics and Control.
