In this thesis, an energy planning for over-actuated unmanned road vehicles (URVs) with redundant steering configuration is proposed. In fact, indicators on the road geometry, the redundancy of actuation, the optimal velocity profile and the driving mode are identified for each segment of the URV's trajectory. Thus, a power consumption estimation model of an over-actuated autonomous driving vehicle is developed. Two methods for power consumption modeling are considered. The first method is based on an analytic model of power consumption, taking into account the degree of steerability, degree of mobility and degree of actuation redundancy. The second method used for power consumption modeling based on data-learning qualitative method namely: Adaptive Neuro Fuzzy Inference System (ANFIS). The latter has been considered in case of the presence of unknown dynamic parameters of the URV and uncertainties about its interaction with the environment. Validation of the estimation of the power consumption has been applied of real autonomous vehicle called RobuCar. Energy planning strategy has been built using two approaches, discrete and continuous. The discrete approach depends on a construction of an energy digraph with all feasible configurations taking into account kinematic and dynamic constraints based on a 3D grid map setup, according to: velocity, arc-length, driving mode. In this weighted directed graph, the edges describe the consumed energy by the UAV along a segment of a trajectory. An optimization algorithm is applied on the digraph to get a global optimal solution combining driving mode, power consumption and velocity profile of the URV. The continuous approach is based on a multi-criteria optimization strategy using genetic algorithms (NSGA-II). Then a real road path is considered and modeled by using two smooth geometrical combinations: the first one is {lines, clothoids and arcs}, and the second one is {lines and Pythagorean Hodograph (PH) curves}. The energy planning strategy is then applied to the generated paths. Also, a directed graph is built to synthesis the optimal velocity profile that minimizes the overall energy consumption while accounting for all driving modes. Results are compared with those given by the dynamic programming method for global offline optimization.

This book elaborates the science and engineering basis for energy-efficient driving in conventional and autonomous cars. After covering the physics of energy-efficient motion in conventional, hybrid, and electric powertrains, the book chiefly focuses on the energy-saving potential of connected and automated vehicles. It reveals how being connected to other vehicles and the infrastructure enables the anticipation of upcoming driving-relevant factors, e.g. hills, curves, slow traffic, state of traffic signals, and movements of nearby vehicles. In turn, automation allows vehicles to adjust their motion more precisely in anticipation of upcoming events, and to save energy. Lastly, the energy-efficient motion of connected and automated vehicles could have a harmonizing effect on mixed traffic, leading to additional energy savings for neighboring vehicles. Building on classical methods of powertrain modeling, optimization, and optimal control, the book further develops the theory of energy-efficient driving. In addition, it presents numerous theoretical and applied case studies that highlight the real-world implications of the theory developed. The book is chiefly intended for undergraduate and graduate engineering students and industry practitioners with a background in mechanical, electrical, or automotive engineering, computer science or robotics.

This paper considers the widespread adoption of electric, shared, autonomous vehicles (AVs). Numerical simulations suggest falling transportation costs and changing center-city land use patterns will reshape the urban form of the city, with several primary consequences. The most likely scenarios suggest substantial household welfare increases, suburbanization, and increased household energy consumption, calling into question claims that autonomous vehicles will save energy.

The Autonomous Vehicle (AV) has been strongly heralded as the most exciting innovation in automobility for decades. Autonomous Vehicles are no longer an innovation of the future (seen only in science fiction) but are now being road-tested for use. And yet while the technical and economic success and possibilities of the AV have been widely debated, there has been a notable lack of discussion around the social, behavioural, and environmental implications. This book is the first to address these issues and to deeply consider the environmental and social sustainability outlook for the AV and how it will impact on communities. Environmental and social sustainability are goals unlike those of technical development (a new tool) and economic development (a new investment). The goal of sustainability is development of societies that live well and equitably within their ecological limits. Is it reasonable and desirable that only technical and economic success comprise the swelling AV parade, or should we be looking at the wider impacts on personal well-being, wider society, and the environment? The uptake for AVs looks to be lengthy, disjointed, and episodic, in large measure because it faces a range of known unknown risks. This book assesses the environmental and social sustainability potential for AVs based on their prospective energy use and their impacts on climate change, urban landscapes, public health, mobility inequalities, and individual and social well-being. It examines public attitudes about AV use and its risk of fostering a rebound effect that compromises potential sustainability gains. The book concludes with a discussion of critical issues involved in sustainable AV diffusion.

In this thesis, a novel approach is presented for the powertrain optimization of electric autonomous transportation vehicles. Two applications of a Level 5 Autonomous Vehicle (AV) are investigated; pure Autonomous Driving (AD) and mixed Human and Autonomous Driving (HAD). The powertrain-system design process is demonstrated for both the applications. In addition, the tradeoffs in using a HAD optimized powertrain for autonomous driving, compared to an AD optimized powertrain is addressed. A system level model is developed in MATLAB and Simulink to predict low-frequency dynamics. Two architectures of the electric powertrain, single (Front Wheel Drive) and double motor (All Wheel Drive) are considered. The optimization problem is set up, which includes defining the objective function, design space, static constraints and inputs for AD and HAD. Comfort requirements for AVs constrain the permissible acceleration while driving. Autonomous drive cycles are represented by optimal trajectories subject to constraints. Optimal powertrains for both the applications are expressed as Pareto fronts. It is observed that there isn’t a particular trend between energy consumption and powertrain power, and even higher powered powertrains provide similar energy consumption values. The energy savings in driving autonomously is primarily attributed to the optimized trajectory, rather than optimized powertrain.

Studienarbeit aus dem Jahr 2020 im Fachbereich Ingenieurwissenschaften - Fahrzeugtechnik, Sprache: Deutsch, Abstract: The article's goals are thus to carefully investigate the safety risks associated with autonomous technology applied to vehicle applications. In section 2 the levels of automation in cars are discussed, in section 3 the sorts of errors and their probable causes are thoroughly examined, section 4 discussed about the tools used in Avs, Section 5 investigates the present state of on-road testing and accidents, and section 6 discusses the opportunities and difficulties for AV safety research. An autonomous vehicle (AV) or driverless vehicle (DV) is one that can operate and execute required functions without human involvement by sensing its surroundings. In addition, AV employs a completely automated driving system to allow the vehicle to adapt to external conditions that a human driver would handle. The major transportation capabilities of a typical car may be fulfilled by an autonomous vehicle. The key distinction is the Driving Automation System (DAS) developed for self-driving vehicles. DAS adds driving automation to the vehicle platform, allowing for major changes in transportation that minimize collisions, energy consumption, pollution, and congestion costs. The SAE prefers the word automated to autonomous. One reason is because the term autonomy has meanings other than electromechanical. A completely self-driving automobile would be self-aware and capable of making its own decisions. To execute software, autonomous vehicles rely on sensors, actuators, complicated algorithms, machine learning systems, and powerful computers. AV is a life-saving system. Any AV malfunction might result in serious human injury or even death. The goal of safety is to safeguard the system against unintentional breakdowns in order to avoid dangers. Autonomous vehicle safety encompasses mechanical system safety as well as electrical and electronic system safety. In t
