Book Description
This important text/reference presents state-of-the-art research on intelligent vehicles, covering not only topics of object/obstacle detection and recognition, but also aspects of vehicle motion control. With an emphasis on both high-level concepts, and practical detail, the text links theory, algorithms, and issues of hardware and software implementation in intelligent vehicle research. Topics and features: presents a thorough introduction to the development and latest progress in intelligent vehicle research, and proposes a basic framework; provides detection and tracking algorithms for structured and unstructured roads, as well as on-road vehicle detection and tracking algorithms using boosted Gabor features; discusses an approach for multiple sensor-based multiple-object tracking, in addition to an integrated DGPS/IMU positioning approach; examines a vehicle navigation approach using global views; introduces algorithms for lateral and longitudinal vehicle motion control.

Book Description
It has long been the goal of engineers to develop tools that enhance our ability to do work, increase our quality of life, or perform tasks that are either beyond our ability, too hazardous, or too tedious to be left to human efforts. Autonomous mobile robots are the culmination of decades of research and development, and their potential is seemingly unlimited. Roadmap to the Future Serving as the first comprehensive reference on this interdisciplinary technology, Autonomous Mobile Robots: Sensing, Control, Decision Making, and Applications authoritatively addresses the theoretical, technical, and practical aspects of the field. The book examines in detail the key components that form an autonomous mobile robot, from sensors and sensor fusion to modeling and control, map building and path planning, and decision making and autonomy, and to the final integration of these components for diversified applications. Trusted Guidance A duo of accomplished experts leads a team of renowned international researchers and professionals who provide detailed technical reviews and the latest solutions to a variety of important problems. They share hard-won insight into the practical implementation and integration issues involved in developing autonomous and open robotic systems, along with in-depth examples, current and future applications, and extensive illustrations. For anyone involved in researching, designing, or deploying autonomous robotic systems, Autonomous Mobile Robots is the perfect resource.

Book Description
When all the magnetometers fail, autonomous vehicle following allows a vehicle to automatically follow its preceding vehicle based on information of the relative distance between the two vehicles. The relative distance is measured by an on-board laser scanning radar (LIDAR) sensor. One issue in autonomous vehicle following is a propagation of errors from one vehicle to another. When errors increase in the upstream direction of a vehicle platoon, the platoon is string unstable. Analysis of string stability is performed, and inter-vehicle communication is suggested as a means to solve the string stability problem. Since vehicle lateral control with rear magnetometers is more challenging, an integrated vehicle steering control scheme, which combines the use of LIDAR and rear magnetometers, is introduced. The solution is verified by both simulations and real-time testing.

Book Description
This report summarizes the research results of TO4233, "Fault Tolerant Autonomous Lateral Control for Heavy Vehicles". This project represents a continuing effort of PATH's research on Automated Highway Systems (AHS) and more specifically in the area of heavy vehicles. Research on the lateral control of heavy vehicles for AHS has been going on at PATH since 1993. MOU129, "Steering and Braking Control of Heavy Duty Vehicles" was the first project and it was followed by MOU242, "Lateral Control of Commercial Heavy Duty Vehicle". Both projects were concerned mostly with the theoretical portion of the problem, i.e. model development, analysis of the dynamic model from the lateral control point of view, and the lateral controller designs. The first experimental results were shown in MOU289 (MOU313), "Lateral Control of Heavy Duty Vehicles for Automated Highway Systems", where the theoretical model was validated and calibrated to the dynamic behavior of an actual tractor-semitrailer vehicle, which was obtained and instrumented. In addition, preliminary closed-loop experiments were performed. A more comprehensive study on a large variety of control strategies was presented in MOU385 and TO4201, "Robust Lateral Control of Heavy Duty Vehicles". More specifically, three types of nonlinear and adaptive controllers for lateral control of heavy vehicles were analyzed theoretically and compared experimentally. All the research efforts mentioned above have been extremely valuable for the development of automated highway vehicles; however they assume the existence of a fully operational magnet-magnetometer scheme. To be more specific, all the results are based on the assumption that each heavy vehicle is equipped with two banks of magnetic sensors, one mounted on the front bumper and the other mounted on the rear bumper of the trailer. The road is also implanted with equally spaced magnets whose magnetic field is used to measure the vehicle's lateral deviation from the road centerline ("lane-keeping control"). Up to now, no heavy-vehicle-related report has discussed the case of vehicle lateral performance under the existence of faults. This problem is very important, since safety and reliability are the primary requirements for the success of AHS. This report addresses the problem of fault tolerant control of heavy vehicles by proposing a secondary system that implements "autonomous vehicle following" instead of "lanekeeping".

Book Description
Robotics began as a science fiction creation which has become quite real, first in assembly line operations such as automobile manufacturing, aeroplane construction etc. They have now reached such areas as the internet, ever-multiplying-medical uses and sophisticated military applications. Control of today's robots is often remote which requires even more advanced computer vision capabilities as well as sensors and interface techniques. Learning has become crucial for modern robotic systems as well. This book brings together leading research in this exciting field.
