Download or read book Vehicle Simulation written by Alfred T. Lee and published by CRC Press. This book was released on 2017-11-13 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Driving in Virtual Reality written by Björn Blissing and published by Linköping University Electronic Press. This book was released on 2020-09-02 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Two Wheelistic written by and published by . This book was released on 2021 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the development of an immersive, high-fidelity virtual reality (VR) cycling simulator, where one can ride a stationary bicycle in a simulated virtual environment and interact with other road users (e.g., drivers). Inspired by driving simulators, a VR cycling simulator has potential to become a valuable tool for conducting traffic safety research involving bicyclists. The hardware and software development and integration were described in detail as a reference for others that may want to build similar systems. The VR simulation includes a representation of a real-world urban environment with a road network, and utilizes a VR headset coupled with an appropriate stationary bike system setup. The first phase of development was focused on an immersive, interactive simulator, in which users are able to control their movements within the virtual environment. They control their speed by pedaling the stationary bike and can steer using buttons on the handlebar-mounted controllers. This aspect of the simulator is instrumental in applications that require observing participants' cycling behaviors in a safe, virtual environment. Validation was performed to ensure the cycling simulator functioned at realistic speeds and in accordance with the user's input. The second development phase focused on a use case for driver education and training, presented through a variety of common dangerous bicyclist encounters programmed into VR scenarios. Drivers who have limited bicycling experience can experience these scenarios in a safe, virtual setting to better understand the bicyclist's perspective.

Available in PDF, EPUB and Kindle. Book excerpt: This book concisely describes the technologies, human perception, and cognition issues relevant to autonomous vehicles. It also gives an insight in the changes bring about our future everyday lives. Autonomous vehicles are the future of the automobile industry. Automated driving (AD), also called self-driving, raises however several multiple questions, among them those of user safety and acceptation. Comprehensive HMI system design, with windshield display technics, will be necessary to deal with driving task delegations, bringing the use of VR or augmented reality (AR) technologies. In addition, the use of VR for all the vehicle interiors will progressively be proposed for entertainment, online business activities and for modified visual motion perception to alleviate car sickness, a form of motion sickness. Indeed, car sickness is already well known for many passengers, especially when reading or operating smartphones or other display devices. It is called to increase significantly with the introduction of autonomous vehicles where all users will be for long periods in various sitting positions. These two new trends, AD and VR, are already modifying our relationship with the world and the society. All together, they will change our way of life forever. The book will be of interest to professionals in the auto industry, researchers in automotive engineering and computer science and all those interested in the future of transport.

This book was released on 2013-05-15 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a survey of past and recent developments on human walking in virtual environments with an emphasis on human self-motion perception, the multisensory nature of experiences of walking, conceptual design approaches, current technologies, and applications. The use of Virtual Reality and movement simulation systems is becoming increasingly popular and more accessible to a wide variety of research fields and applications. While, in the past, simulation technologies have focused on developing realistic, interactive visual environments, it is becoming increasingly obvious that our everyday interactions are highly multisensory. Therefore, investigators are beginning to understand the critical importance of developing and validating locomotor interfaces that can allow for realistic, natural behaviours. The book aims to present an overview of what is currently understood about human perception and performance when moving in virtual environments and to situate it relative to the broader scientific and engineering literature on human locomotion and locomotion interfaces. The contents include scientific background and recent empirical findings related to biomechanics, self-motion perception, and physical interactions. The book also discusses conceptual approaches to multimodal sensing, display systems, and interaction for walking in real and virtual environments. Finally, it will present current and emerging applications in areas such as gait and posture rehabilitation, gaming, sports, and architectural design.

Download or read book Development of an environment framework for a modular vehicle simulation system written by Xavier Bas Ferrer and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent vehicle developments are forced by continuously decreasing development times. To reach this aim virtual methods are necessary. Concerning the research area of vehicle dynamics, virtual analyses play an important role during the whole development process of a vehicle. Vehicle dynamics simulations using different manoeuvres, models and environments become a key component. This important role is even more significant for the early design phase of the vehicle, where only few and uncertain parameters are available. The present thesis expands the simulation platform MOVES2, designed for modular vehicle dynamic simulations during the early design phase, at the Institute of Automotive Engineering at Graz University of Technology. The presented expansion implements a set of modules to generate arbitrary roads within arbitrary scenarios, to animate the simulated vehicle motion within a virtual reality world based on the generated scenario, to define the desired trajectory for the simulation and to configure the modelling complexity of the model. To ensure a high level of user-friendliness, the Graphical User Interface of MOVES2 manages the required data from these modules, by creating, editing and deleting it.
