Available in PDF, EPUB and Kindle. Book excerpt: Modern automobiles are equipped with various driver assistance functions which enhance safety and relieve driver fatigue. With the recent development of sensor technology, the Adaptive Cruise Control (ACC) system has been put into practice. This thesis investigates several aspects for the ACC system including (1) smooth reaction of the host vehicle to the cutting in and out of lead vehicles, (2) real-time optimal profile generation for stop-and-go motions, (3) optimal feedback controller design, and (4) extension to Cooperative Adaptive Cruise Control (CACC) systems. The ACC system should maintain an appropriate relative distance to the lead vehicle and should also maintain the desired speed set by the driver if there is no lead vehicle or if the speed of the lead vehicle is faster than the desired speed. Also, it should react smoothly when the lead vehicle cuts out or if a new lead vehicle cuts in from a side lane. This thesis introduces the virtual lead vehicle scheme to prevent the switching between the distance control and the speed control. By controlling the motion of the virtual lead vehicle to be smooth, the scheme could provide smooth reaction of the host vehicle to the cutting in and out of lead vehicles. Linear Quadratic (LQ) optimal control scheme is utilized to find the control gains for the virtual lead vehicle and the host vehicle. Variable weights are utilized in LQ for the virtual lead vehicle. With the variable weights, the motion of the virtual lead vehicle is controlled to be smooth when there is no safety threat while ensuring that the virtual lead vehicel is still responsive and fast when a dangerous situation occurs. ACC with Stop-and-Go and the Cooperative Adaptive Cruise Control (CACC) system are extensions of the conventional ACC system. Stop-and-Go system is targeted to be used in urban driving situation where the lead vehicle can stop completely. In that case, the Stop-and-Go system should have a capability to stop the host vehicle completely. The constant time-headway policy used to find the appropriate relative distance causes undesirable motion for a complete stop. In this thesis a sliding controller is utilized to control the complete stopping motion. To find the optimal stopping trajectory, a constrained Quadratic Programming (QP) problem is solved. A constrained QP is also used to find the optimal velocity profile when the stopped vehicle is to resume motion. Multi-resolution formulations and the Lemke algorithm are utilized to find the optimal trajectories in real time. The CACC system utilizes wireless communication so that the vehicles in the network can share information with other vehicles. In this thesis, a centralized controller is designed by LQ optimal control scheme and potential benefits and problems are addressed. A Kalman filter with variable measurement noise covariance is introduced to compensate the lost data through the wireless network associated with the CACC system. The proposed control schemes have been verified through simulations.

Download or read book Handbook of Intelligent Vehicles written by Azim Eskandarian and published by Springer. This book was released on 2012-02-26 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Intelligent Vehicles provides a complete coverage of the fundamentals, new technologies, and sub-areas essential to the development of intelligent vehicles; it also includes advances made to date, challenges, and future trends. Significant strides in the field have been made to date; however, so far there has been no single book or volume which captures these advances in a comprehensive format, addressing all essential components and subspecialties of intelligent vehicles, as this book does. Since the intended users are engineering practitioners, as well as researchers and graduate students, the book chapters do not only cover fundamentals, methods, and algorithms but also include how software/hardware are implemented, and demonstrate the advances along with their present challenges. Research at both component and systems levels are required to advance the functionality of intelligent vehicles. This volume covers both of these aspects in addition to the fundamentals listed above.

Download or read book Adaptive Cruise Control System Design and Its Impact on Traffic Flow written by and published by . This book was released on 2005 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study resolves the controversy over the stability of constant time-gap policy for highway traffic flow. Previous studies left doubt as to the effectiveness of constant time-gap policies and whether they maintain stability in all traffic conditions. The results of this study prove that the constant time gap policy is in fact stable to a limit. At this limit, depending on the boundary conditions, conditions lose their stability. This study develops alternative ways to maintain the balance between safety and traffic flow for ACC vehicles that does not rely on constant time-gap policies. New spacing policies will create more stability, and therefore safer conditions, and allow for greater traffic capacity.

Book Synopsis Design of Adaptive Cruise Controller by : Subashri Vasudevan
Download or read book Design of Adaptive Cruise Controller written by Subashri Vasudevan and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main aim of the project is to design model based approach for Adaptive Cruise Control system which works efficiently under the STOP & GO scenarios. A significant number of accidents could be avoided through timely threat recognition and appropriate actions of collision avoidance. This may be achieved by suitable warning to the driver or by automatic support to longitudinal or lateral control of vehicle. The Adaptive Cruise Controller (ACC) is mainly a comforting system that helps in controlling the speed of the vehicle; at the same time it ensures the distance from the preceding vehicle is safer enough to avoid collision. But the driver remains responsible for steering. The speed can be decelerated/ accelerated in steps using the buttons available in the ACC. If deceleration of the ACC is not sufficient enough to avoid a collision, it warns the driver with a warning sound. All these are clearly drafted in the report and is presented with proper simulation results. Reader can go through the details and we are sure it would be a good reading.
Book Synopsis Vehicle Dynamics and Control by : Rajesh Rajamani
Download or read book Vehicle Dynamics and Control written by Rajesh Rajamani and published by Springer Science & Business Media. This book was released on 2011-12-21 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Robust Control Design for Active Driver Assistance Systems by : Péter Gáspár
Download or read book Robust Control Design for Active Driver Assistance Systems written by Péter Gáspár and published by Springer. This book was released on 2016-11-18 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph focuses on control methods that influence vehicle dynamics to assist the driver in enhancing passenger comfort, road holding, efficiency and safety of transport, etc., while maintaining the driver’s ability to override that assistance. On individual-vehicle-component level the control problem is formulated and solved by a unified modelling and design method provided by the linear parameter varying (LPV) framework. The global behaviour desired is achieved by a judicious interplay between the individual components, guaranteed by an integrated control mechanism. The integrated control problem is also formalized and solved in the LPV framework. Most important among the ideas expounded in the book are: application of the LPV paradigm in the modelling and control design methodology; application of the robust LPV design as a unified framework for setting control tasks related to active driver assistance; formulation and solution proposals for the integrated vehicle control problem; proposal for a reconfigurable and fault-tolerant control architecture; formulation and solution proposals for the plug-and-play concept; detailed case studies. Robust Control Design for Active Vehicle Assistance Systems will be of interest to academic researchers and graduate students interested in automotive control and to control and mechanical engineers working in the automotive industry. Advances in Industrial Control aims to report and encourage the transfer of technology in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. The series offers an opportunity for researchers to present an extended exposition of new work in all aspects of industrial control.
