In order to handle the complex task of driving, they need the ability to make decisions regarding other road users, plan a trajectory, and control the vehicle, responding online to an evolving environment. For model-based control, it is important to use models that capture the full range of the vehicle's dynamics. We develop a tire model that is computationally tractable and useful in scenarios ranging from a stop-and-go maneuver to driving at the limits of road-tire friction. A model-based steering controller successfully demonstrates the efficacy of this tire model even when the vehicle is sliding on low-friction surfaces. In addition to being able to control the vehicle, an AV architecture must also be able to make discrete decisions regarding obstacles in the environment. Ultimately, these decisions are carried out by a controller commanding steering and longitudinal inputs, which motivates building a system that makes decisions based on the capabilities of the underlying controller. Our novel architecture partitions the drivable space into discrete options, solves a nonlinear optimization in each option in parallel, and then picks the solution that best satisfies high-level objectives such as safety and efficiency. Finally, frameworks for automated vehicles need to be designed with human values in mind. Safety is a top priority and is codified in legal texts as duty of due care. By leveraging the architecture described above to realize these human values, the vehicle drives safely and comfortably in an overtaking maneuver with oncoming traffic.

This book was released on 2020-04-25 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes an effective decision-making and planning architecture for enhancing the navigation capabilities of automated vehicles in the presence of non-detailed, open-source maps. The system involves dynamically obtaining road corridors from map information and utilizing a camera-based lane detection system to update and enhance the navigable space in order to address the issues of intrinsic uncertainty and low-fidelity. An efficient and human-like local planner then determines, within a probabilistic framework, a safe motion trajectory, ensuring the continuity of the path curvature and limiting longitudinal and lateral accelerations. LiDAR-based perception is then used to identify the driving scenario, and subsequently re-plan the trajectory, leading in some cases to adjustment of the high-level route to reach the given destination. The method has been validated through extensive theoretical and experimental analyses, which are reported here in detail.

Available in PDF, EPUB and Kindle. Book excerpt: This book details cutting-edge research into human-like driving technology, utilising game theory to better suit a human and machine hybrid driving environment. Covering feature identification and modelling of human driving behaviours, the book explains how to design an algorithm for decision making and control of autonomous vehicles in complex scenarios. Beginning with a review of current research in the field, the book uses this as a springboard from which to present a new theory of human-like driving framework for autonomous vehicles. Chapters cover system models of decision making and control, driving safety, riding comfort and travel efficiency. Throughout the book, game theory is applied to human-like decision making, enabling the autonomous vehicle and the human driver interaction to be modelled using noncooperative game theory approach. It also uses game theory to model collaborative decision making between connected autonomous vehicles. This framework enables human-like decision making and control of autonomous vehicles, which leads to safer and more efficient driving in complicated traffic scenarios. The book will be of interest to students and professionals alike, in the field of automotive engineering, computer engineering and control engineering.

Download or read book Integrated Motion Planning and Control for Automated Vehicles Up to the Limits of Handling written by Vincent Andreas Laurense and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to keep self-driving cars safe, it is important that these vehicles can plan safe trajectories through their environment and have the ability to robustly use their full tire-force potential. Racing at the limits of handling provides a purposefully challenging scenario for the development of reliable vehicle-motion planning and control techniques, as race cars are constantly pushed to their physical limits. With a common trajectory-tracking architecture for automated vehicle control, steering provides path-tracking control, and the throttle and brakes are used to track a desired speed profile. For the specific application of racing, this speed profile can be designed to fully use the tire-force potential. Experimental data show that a preexisting control framework based on this approach can match the lap time of an amateur race-car driver, but a professional race-car driver proves to be slightly faster. It is demonstrated with both experimental results and an analytical method that with this decoupled path-tracking and speed-tracking controller, an automated vehicle is prone to either under-utilize the tires or lose control over the path-tracking dynamics when unintentionally operating beyond the limit. Furthermore, a professional race-car driver successfully operates the vehicle with a control strategy that seems fundamentally different from trajectory tracking. Namely, he shows significant lap-to-lap variations in both speed and path, but he is consistently faster than automated trajectory-tracking control. This inspires new strategies for automated vehicle control. In this context, two novel feedback-control strategies are presented, which employ slip-angle control to robustly use the vehicle's full tire-force potential, while speed control provides the path-tracking functionality. Subsequently, in order to have the ability to also adjust the vehicle's path, a Nonlinear Model Predictive Control (NMPC) framework is presented which can trade-off longitudinal and lateral control inputs. Experimental results demonstrate that this controller successfully coordinates the inputs at the limits of handling. However, the computational burden of this NMPC framework limits the length of the planning horizon for real-time control, which in turn inhibits its ability to adjust the vehicle's path and speed. To address this issue, a new NMPC framework is developed, which serially cascades vehicle models of different levels of complexity in the planning horizon. Experimental results on an automated race car demonstrate the benefits of this new concept, with a high quality of control provided by a high-fidelity vehicle model in the near-term planning horizon, and significant extension of the planning horizon with a low-fidelity model.

This book was released on 2022-05-31 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intelligent vehicle will play a crucial and essential role in the development of the future intelligent transportation system, which is developing toward the connected driving environment, ultimate driving safety, and comforts, as well as green efficiency. While the decision making, planning, and control are extremely vital components of the intelligent vehicle, these modules act as a bridge, connecting the subsystem of the environmental perception and the bottom-level control execution of the vehicle as well. This short book covers various strategies of designing the decision making, trajectory planning, and tracking control, as well as share driving, of the human-automation to adapt to different levels of the automated driving system. More specifically, we introduce an end-to-end decision-making module based on the deep Q-learning, and improved path-planning methods based on artificial potentials and elastic bands which are designed for obstacle avoidance. Then, the optimal method based on the convex optimization and the natural cubic spline is presented. As for the speed planning, planning methods based on the multi-object optimization and high-order polynomials, and a method with convex optimization and natural cubic splines, are proposed for the non-vehicle-following scenario (e.g., free driving, lane change, obstacle avoidance), while the planning method based on vehicle-following kinematics and the model predictive control (MPC) is adopted for the car-following scenario. We introduce two robust tracking methods for the trajectory following. The first one, based on nonlinear vehicle longitudinal or path-preview dynamic systems, utilizes the adaptive sliding mode control (SMC) law which can compensate for uncertainties to follow the speed or path profiles. The second one is based on the five-degrees-of-freedom nonlinear vehicle dynamical system that utilizes the linearized time-varying MPC to track the speed and path profile simultaneously. Toward human-automation cooperative driving systems, we introduce two control strategies to address the control authority and conflict management problems between the human driver and the automated driving systems. Driving safety field and game theory are utilized to propose a game-based strategy, which is used to deal with path conflicts during obstacle avoidance. Driver's driving intention, situation assessment, and performance index are employed for the development of the fuzzy-based strategy. Multiple case studies and demos are included in each chapter to show the effectiveness of the proposed approach. We sincerely hope the contents of this short book provide certain theoretical guidance and technical supports for the development of intelligent vehicle technology.

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses higher-lower level decision autonomy for autonomous vehicles, and discusses the addition of a novel architecture to cover both levels. The proposed framework's performance and stability are subsequently investigated by employing different meta-heuristic algorithms. The performance of the proposed architecture is shown to be largely independent of the algorithms employed; the use of diverse algorithms (subjected to the real-time performance of the algorithm) does not negatively affect the system's real-time performance. By analyzing the simulation results, the book demonstrates that the proposed model provides perfect mission timing and task management, while also guaranteeing secure deployment. Although mainly intended as a research work, the book's review chapters and the new approaches developed here are also suitable for use in courses for advanced undergraduate or graduate students.
