Modelling, Simulation and Control of Two-Wheeled Vehicles presents all of the unique features of two-wheeled vehicles, comprehensively covering the main methods, tools and approaches to address the modelling, simulation and control design issues. With contributions from leading researchers, this book also offers a perspective on the future trends in the field, outlining the challenges and the industrial and academic development scenarios. Extensive reference to real-world problems and experimental tests is also included throughout. Key features: The first book to cover all aspects of two-wheeled vehicle dynamics and control Collates cutting-edge research from leading international researchers in the field Covers motorcycle control – a subject gaining more and more attention both from an academic and an industrial viewpoint Covers modelling, simulation and control, areas that are integrated in two-wheeled vehicles, and therefore must be considered together in order to gain an insight into this very specific field of research Presents analysis of experimental data and reports on the results obtained on instrumented vehicles. Modelling, Simulation and Control of Two-Wheeled Vehicles is a comprehensive reference for those in academia who are interested in the state of the art of two-wheeled vehicles, and is also a useful source of information for industrial practitioners.

This book covers the problem of fidelity in the design of virtual environments with specific reference to the design of vehicle simulators. The default design goal has been on the physical replication of a given real-world environment and, in the case of vehicles, the specific appearance and function of vehicle components. This book discusses that perceptual, rather than physical, fidelity of a virtual environment, should be the design goal and the principal purpose is to produce human behavior. This book provides the rationale and design guidance to maximize perceptual fidelity in the development of virtual environments, and therefore maximize the costeffectiveness as well.

In the last decades, there has been a substantial increase in the development of complex active safety systems for automotive vehicles. These systems need to be tested for verification and validation to ensure that the system intervenes in the correct situations using the correct measures. There are multiple methods available to perform such testing. Software-in-the-loop and hardware-in-the-loop testing offer effective driverless testing. Other methods increase the fidelity by including human drivers, such as driving simulators and experiments performed at test tracks. This thesis examines vehicle-in-the-loop testing, an innovative method where the driver of a real vehicle wears a head-mounted display that displays virtual targets. This method combines the benefits of driving simulators with the benefits of using a real vehicle on a test track. Driving simulators offer repeatability, safety, and the possibility of complex interactions between actors. In contrast, the real vehicle provides the correct vehicle dynamics and motion feedback. There is a need to know how the technology behind the method might influence the results from vehicle-in-the-loop testing. Two techniques for vehicle-in-the-loop systems are studied. The first involves video-see through head-mounted displays, where the focus of the research is on the effects of visual latency on driving behavior. The results show that lateral driving behavior changes with added latency, but longitudinal behavior appears unaffected. The second system uses an opaque head-mounted display in an entirely virtual world. The research shows that this solution changes speed perception and results in a significant degradation in performance of tasks dependent on visual acuity. This research presents results that are relevant to consider when developing vehicle-in-the-loop platforms. The results are also applicable when choosing scenarios for this test method. Dagens fordon innehåller fler och fler säkerhetssystem. Vissa av dessa system ger varningar i potentiellt kritiska trafiksituationer. Det finns också mer komplexa system som tillfälligt kan ta kontroll över fordonet för att förhindra en olycka eller åtminstone mildra effekterna. Komplexiteten hos dessa system innebär att man måste genomföra omfattande tester. Både för att se att systemen reagerar vid rätt tidpunkt, men också för att se att valet av åtgärd är korrekt. Det finns många olika sätt att testa dessa system. Man börjar vanligtvis med simuleringar av programvara och hårdvara. Därefter kan systemet introduceras i ett fordon för att se vilka effekter systemet har när det interagerar med en riktig förare. Att utföra tester med förare ställer dock höga säkerhetskrav, och det är ofta svårt att samordna komplexa trafiksituationer på en testbana. Traditionellt har körsimulatorer varit ett naturligt alternativ eftersom de kan utföra komplexa scenarier i en säker miljö. Denna avhandling undersöker en testmetod där man utrustar föraren med en virtual reality-display. Genom att presentera omvärlden med hjälp av virtual reality, så kan man genomföra scenarion som tidigare varit omöjliga på en testbana. Det kan dock finnas inbyggda begränsningar i virtual reality tekniken som kan påverka körbeteendet. Det är därför viktigt att hitta och kvantifiera dessa effekter för att kunna lita på resultaten från testmetoden. Att känna till dessa effekter på körbeteendet dessutom kan hjälpa till att avgöra vilka typer av scenarier som är lämpade för denna testmetod. Det är också viktig information för att avgöra var man bör fokusera den tekniska utvecklingen av testutrustningen.

With respect to the future urban mobility, modern electrical bicycles, advanced motorcycles and innovative two-wheeled vehicles are arresting enormous amount of attention. Especially, model-based control and optimal trajectory planning for such vehicles are important to the research and development of the future. Therefore, a reliable and yet usable vehicle model as well as a systematic approach to motion control for two-wheeled vehicles are essential, to which this work makes a contribution. Currently available two-wheeled vehicle models are mostly either too complex to be used for a systematic control synthesis, or too simple such that the physical behaviour of the vehicle is no more represented. In this thesis, a unifying approach to modelling and control for autonomous two-wheeled vehicles is presented. The resulting model is generally valid and physically detailed enough to represent the characteristic dynamical behaviour such as the self-stability. At the same time, it is suited to a systematic control synthesis. Furthermore, the systematic extenddability, for instance by a rider, is demonstrated. The model is validated by simulations and by comparison to well-known models from the literature. The proposed vehicle model is derived in the Lagrangian and Hamiltonian framework and used for model-based optimal trajectory planning. Furthermore, a passivity-based trajectory tracking controller is designed based on the resulting port-Hamiltonian system using the so-called generalised canonical transformations. Such a controller is physically interpretable and robust against parameter uncertainties. To this end, existing approaches of passivity-based controller design are extended and adjusted for two-wheeled vehicles. Finally, a prototype two-wheeled vehicle is introduced which is used for experimental validation of the model and to demonstrate motion control algorithms for autonomous two-wheeled vehicles.

Passive and active safety systems (ABS, ESP, safety belts, airbags, etc.) represent a major advance in terms of safety in motoring. They are increasingly developed and installed in cars and are beginning to appear in twowheelers. It is clear that these systems have proven efficient, although there is no information about their actual operation by current users. The authors of this book present a state of the art on safety systems and assistance to driving and their two-wheeled counterparts. The main components constituting a driving simulator are described, followed by a classification of robotic architectures. Then, a literature review on driving simulators and two-wheeled vehicles is presented. The aim of the book is to point out the differences of perspectives between motor vehicles and motorcycles to identify relevant indicators to help in choosing the mechanical architecture of the motorcycle simulator and appropriate controls. Contents 1. Driving Simulation. 2. Architecture of Driving Simulators. 3. Dynamics of Two-Wheeled Vehicles. 4. Two-Wheeled Riding Simulator: From Design to Control.
