Book Description
Vehicle Collision Dynamics provides a unified framework and timely collection of up-to-date results on front crash, side crash and car to car crashes. The book is ideal as a reference, with an approach that's simple, clear, and easy to comprehend. As the mathematical and software-based modelling and analysis of vehicle crash scenarios have not been systematically investigated, this is an ideal source for further study. Numerous academic and industry studies have analyzed vehicle safety during physical crash scenarios, thus material responses during crashes serve as one of the most important performance indices for mechanical design problems. In addition to mathematical methodologies, this book provides thorough coverage of computer simulations, software-based modeling, and an analysis of methods capable of providing more flexibility. - Unifies existing and emerging concepts concerning vehicle crash dynamics - Provides a series of latest results in mathematical-based modeling from front and oblique perspectives - Contains almost everything needed to capture the essence of model development and analysis for vehicle crash - Includes both numerical and simulation results given in each chapter - Presents a comprehensive, up-to-date reference that encourages further study

Book Description
Written for the reconstructionist, attorney, automotive engineer, or other interested professional, it examines the science of reconstructing and analyzing a low speed automobile accident. Learn how to analyze accidents that result in little or no vehicle damage, how the final position of a vehicle indicates speed much higher than the driver claims and what are potential injuries and threshold loads for injury to various parts of the body arise from low speed collisions. Dr. Watts explains basic concepts of physics, and then applies them to accident reconstruction. The text will be readily understood by any reader with a basic understanding of accident reconstruction, however, full details and equation derivations are provided for those with either higher technical education or a wish to more fully understand the issues.

Book Description
In recent years, the control of Connected and Automated Vehicles (CAVs) has attracted strong attention for various automotive applications. One of the important features demanded of CAVs is collision avoidance, whether it is a stationary or a moving obstacle. Due to complex traffic conditions and various vehicle dynamics, the collision avoidance system should ensure that the vehicle can avoid collision with other vehicles or obstacles in longitudinal and lateral directions simultaneously. The longitudinal collision avoidance controller can avoid or mitigate vehicle collision accidents effectively via Forward Collision Warning (FCW), Brake Assist System (BAS), and Autonomous Emergency Braking (AEB), which has been commercially applied in many new vehicles launched by automobile enterprises. But in lateral motion direction, it is necessary to determine a flexible collision avoidance path in real time in case of detecting any obstacle. Then, a path-tracking algorithm is designed to assure that the vehicle will follow the predetermined path precisely, while guaranteeing certain comfort and vehicle stability over a wide range of velocities. In recent years, the rapid development of sensor, control, and communication technology has brought both possibilities and challenges to the improvement of vehicle collision avoidance capability, so collision avoidance system still needs to be further studied based on the emerging technologies. In this book, we provide a comprehensive overview of the current collision avoidance strategies for traditional vehicles and CAVs. First, the book introduces some emergency path planning methods that can be applied in global route design and local path generation situations which are the most common scenarios in driving. A comparison is made in the path-planning problem in both timing and performance between the conventional algorithms and emergency methods. In addition, this book introduces and designs an up-to-date path-planning method based on artificial potential field methods for collision avoidance, and verifies the effectiveness of this method in complex road environment. Next, in order to accurately track the predetermined path for collision avoidance, traditional control methods, humanlike control strategies, and intelligent approaches are discussed to solve the path-tracking problem and ensure the vehicle successfully avoids the collisions. In addition, this book designs and applies robust control to solve the path-tracking problem and verify its tracking effect in different scenarios. Finally, this book introduces the basic principles and test methods of AEB system for collision avoidance of a single vehicle. Meanwhile, by taking advantage of data sharing between vehicles based on V2X (vehicle-to-vehicle or vehicle-to-infrastructure) communication, pile-up accidents in longitudinal direction are effectively avoided through cooperative motion control of multiple vehicles.

Book Description
The police crash investigation department requires an engineering study of a vehicle crash before presenting a case to the judicial system. Vehicle crash reconstruction simulations establish new scientific basis for the judiciary system. Computer models are used to reconstruct the vehicle performance, since the dynamic performance of a vehicle collision cannot be repeated in real time. Vehicle dynamics is the engineering study of a vehicle based on mechanics and physics. This thesis uses modern techniques in combination with the information of Event Data Recorders (EDR) to help the judiciary system identify the safety parameters and condition of vehicles. The research analysis mainly focuses on the performance of police vehicles. The EDR is a device installed in the vehicle to record how the driver responds to a crash event. Since 2004 the event data recorders are mandatory in every vehicle. Also, the EDR is able to analyze the change in velocity of the vehicle at the time of the impact. The analysis of the change in velocity allows a base structure for computer simulation. A 3-D computer solid model of a 2004 Ford Crown Victoria is developed using Solidwoks. Also, dynamic computer simulations are developed using Adams View. The solid models consist of a tire assembly, a suspension assembly and a vehicle structure. These are assembled to form a complete model of the vehicle. The main objective is to analyze the vehicle's performance during tactile driving maneuverers. The second objective is to provide new alternative methods to demonstrate a crash reconstruction to the judicial system. This method will provide a simpler, faster, and more accurate analysis of a vehicle dynamics. Additionally, the outcome of these simulations will provide a theoretical basis for future vehicle design.

Book Description
The book starts with an historical overview of road vehicles. The first part deals with the forces exchanged between the vehicle and the road and the vehicle and the air with the aim of supplying the physical facts and the relevant mathematical models about the forces which dominate the dynamics of the vehicle.The second part deals with the dynamic behaviour of the vehicle in normal driving conditions with some extensions towards conditions encountered in high-speed racing driving.
