This book was released on 2017-03-30 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern vehicles are complex systems. Different design stages for such a complex system include evaluation using models and submodels, hardware-in-the-loop systems and complete vehicles. Once a vehicle is delivered to the market evaluation continues by the public. One kind of tool that can be used during many stages of a vehicle lifecycle is driving simulators. The use of driving simulators with a human driver is commonly focused on driver behavior. In a high fidelity moving base driving simulator it is possible to provide realistic and repetitive driving situations using distinctive features such as: physical modelling of driven vehicle, a moving base, a physical cabin interface and an audio and visual representation of the driving environment. A desired but difficult goal to achieve using a moving base driving simulator is to have behavioral validity. In other words, A driver in a moving base driving simulator should have the same driving behavior as he or she would have during the same driving task in a real vehicle.". In this thesis the focus is on high fidelity moving base driving simulators. The main target is to improve the behavior validity or to maintain behavior validity while adding complexity to the simulator. One main assumption in this thesis is that systems closer to the final product provide better accuracy and are perceived better if properly integrated. Thus, the approach in this thesis is to try to ease incorporation of such systems using combinations of the methods hardware-in-the-loop and distributed simulation. Hardware-in-the-loop is a method where hardware is interfaced into a software controlled environment/simulation. Distributed simulation is a method where parts of a simulation at physically different locations are connected together. For some simulator laboratories distributed simulation is the only feasible option since some hardware cannot be moved in an easy way. Results presented in this thesis show that a complete vehicle or hardware-in-the-loop test laboratory can successfully be connected to a moving base driving simulator. Further, it is demonstrated that using a framework for distributed simulation eases communication and integration due to standardized interfaces. One identified potential problem is complexity in interface wrappers when integrating hardware-in-the-loop in a distributed simulation framework. From this aspect, it is important to consider the model design and the intersections between software and hardware models. Another important issue discussed is the increased delay in overhead time when using a framework for distributed simulation.

Book excerpt: Development of new functionality and smart systems for different types of vehicles is accelerating with the advent of new emerging technologies such as connected and autonomous vehicles. To ensure that these new systems and functions work as intended, flexible and credible evaluation tools are necessary. One example of this type of tool is a driving simulator, which can be used for testing new and existing vehicle concepts and driver support systems. When a driver in a driving simulator operates it in the same way as they would in actual traffic, you get a realistic evaluation of what you want to investigate. Two advantages of a driving simulator are (1.) that you can repeat the same situation several times over a short period of time, and (2.) you can study driver reactions during dangerous situations that could result in serious injuries if they occurred in the real world. An important component of a driving simulator is the vehicle model, i.e., the model that describes how the vehicle reacts to its surroundings and driver inputs. To increase the simulator realism or the computational performance, it is possible to divide the vehicle model into subsystems that run on different computers that are connected in a network. A subsystem can also be replaced with hardware using so-called hardware-in-the-loop simulation, and can then be connected to the rest of the vehicle model using a specified interface. The technique of dividing a model into smaller subsystems running on separate nodes that communicate through a network is called distributed simulation. This thesis investigates if and how a distributed simulator design might facilitate the maintenance and new development required for a driving simulator to be able to keep up with the increasing pace of vehicle development. For this purpose, three different distributed simulator solutions have been designed, built, and analyzed with the aim of constructing distributed simulators, including external hardware, where the simulation achieves the same degree of realism as with a traditional driving simulator. One of these simulator solutions has been used to create a parameterized powertrain model that can be configured to represent any of a number of different vehicles. Furthermore, the driver's driving task is combined with the powertrain model to monitor deviations. After the powertrain model was created, subsystems from a simulator solution and the powertrain model have been transferred to a Modelica environment. The goal is to create a framework for requirement testing that guarantees sufficient realism, also for a distributed driving simulation. The results show that the distributed simulators we have developed work well overall with satisfactory performance. It is important to manage the vehicle model and how it is connected to a distributed system. In the distributed driveline simulator setup, the network delays were so small that they could be ignored, i.e., they did not affect the driving experience. However, if one gradually increases the delays, a driver in the distributed simulator will change his/her behavior. The impact of communication latency on a distributed simulator also depends on the simulator application, where different usages of the simulator, i.e., different simulator studies, will have different demands. We believe that many simulator studies could be performed using a distributed setup. One issue is how modifications to the system affect the vehicle model and the desired behavior. This leads to the need for methodology for managing model requirements. In order to detect model deviations in the simulator environment, a monitoring aid has been implemented to help notify test managers when a model behaves strangely or is driven outside of its validated region. Since the availability of distributed laboratory equipment can be limited, the possibility of using Modelica (which is an equation-based and object-oriented programming language) for simulating subsystems is also examined. Implementation of the model in Modelica has also been extended with requirements management, and in this work a framework is proposed for automatically evaluating the model in a tool.

Available in PDF, EPUB and Kindle. Book excerpt: Autonomous and cooperative vehicle systems represent a key priority in the automotive realm. Networked driving simulation can be utilized as a safe, cost-effective experimental replica of real traffic environments in order to support and accelerate the development of such systems. In networked driving simulation, independent and multidisciplinary systems collaborate to achieve a common task: multi-driver traffic scenario simulation. As myriad alternatives of system components are available, developers are typically confronted with high design complexity. A systematic method is required to design platforms of networked driving simulation in accordance with the requirements of different application scenarios. The aim of this thesis is to develop a System-Level Design Framework for Networked Driving Simulation. The design framework consists of a procedure model and configuration software. The procedure model describes the necessary phases and the involved tasks to design application-oriented platforms of networked driving simulation. The configuration software embeds functions and decision-making processes that enable non-expert users to create different system models. The design framework was validated by generating system models and developing platforms of networked driving simulation for three different application scenarios. ; eng

This book was released on 2020-10-21 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today's society is increasingly software-driven and dependent on powerful computer technology. Therefore it is important that advancements in the low-level processor hardware are made available for exploitation by a growing number of programmers of differing skill level. However, as we are approaching the end of Moore's law, hardware designers are finding new and increasingly complex ways to increase the accessible processor performance. It is getting more and more difficult to effectively target these processing resources without expert knowledge in parallelization, heterogeneous computation, communication, synchronization, and so on. To ensure that the software side can keep up, advanced programming environments and frameworks are needed to bridge the widening gap between hardware and software. One such example is the pattern-centric skeleton programming model and in particular the SkePU project. The work presented in this thesis first redesigns the SkePU framework based on modern C++ variadic template metaprogramming and state-of-the-art compiler technology. It then explores new ways to improve performance: by providing new patterns, improving the data access locality of existing ones, and using both static and dynamic knowledge about program flow. The work combines novel ideas with practical evaluation of the approach on several applications. The advancements also include the first skeleton API that allows variadic skeletons, new data containers, and finally an approach to make skeleton programming more customizable without compromising universal portability.

Download or read book User centered Multi layer Programming Approach to Model Scenarios on Driving Simulators written by Ghasan Bhatti and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Driving simulators are useful tools for researcher in order to study the drivers' behaviour, to analyze road safety features and to evaluate ADAS (Advance Driving Assistance Systems). Modeling scenarios on driving simulators is a critical and complex task for behavioral researcher. It requires specific technical and programming skills, for which researchers are not formally trained. One of the main reasons why designing scenarios is a complex task is the lack of User-Centered Design (UCD) of the scenario authoring tools, which could account for the skills they lack in order to achieve their objectives with driving simulators. The user interfaces are thus not very intuitive and user-friendly in most driving simulators. A User- Centered andMultilayer programming approach is proposed in order to fill the gap between the end-user's skills and the goals they want to achieve with driving simulators. A user study was conducted to gather the user's needs and requirements to model scenarios on driving simulators. Different steps have been identified, followed by the end-users while designing an experimental protocol; moreover, different types of users who interactwith driving simulators have been identified. We propose that the interface to develop an experimental protocol should be split into three sub-interfaces used by different end-users who interact with driving simulators: the Template Builder for Technical persons, the Experiment Builder for Researchers, and the Experiment Interface, for Experiment operators. Using the Experiment Builder, researchers can develop scenarios at high-level exploiting the programming primitives. An evaluation of the approach was conducted on a semi-functional and a functional prototype. During the evaluation, end-users (behavioral researchers) developed experimental protocols on driving simulators. The results have shown that the proposed approach has empowered the non-programmers to model scenarios on driving simulators without any technical or programming help from technical persons. Besides, every driving simulator has a different execution platform. An interoperability framework and a Scenario-Meta Language (SML) is proposed and developed to port the scenarios from one platform to another. The scenarios developed using the multi-layer programming approach can be executed on different driving simulators. The interoperability framework and the meta-language has been successfully tested by integrating them with the SCANeR software.

This book was released on 2021 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced Driver Assistance Systems (ADAS) have been rapidly improving over the last decade with the implementation of more automated features. This will lead to the development of fully autonomous vehicles (AVs) and their deployment into the traffic stream. Although the idea of self-driving cars in society is inevitable, there is much more research that needs to be done before that becomes a reality. Therefore, a transition phase will first occur in which traffic will consist of a mixed configuration of various automated and human-driven vehicles. This will undoubtedly result in consequences as the different levels of AVs and human drivers interact in various roadway environments and distinct traffic characteristics. For that reason, it is imperative to research the full capabilities of all levels of automation and understand their limitations based on the diverse set of roadway environments and various driving scenarios that will be encountered. In this thesis, an attempt was made to begin understanding the capabilities and limitations of AVs in mixed traffic. Given the multitude of environments and scenarios, prioritization was given to a situation that would be common for Texas roadways. Therefore, this thesis develops a driving simulation environment to understand the performance of AVs with respect to traffic safety and efficiency in Texas rural highways and urban roads during a forced lane drop scenario and a merging vehicle maneuver. This prioritization was used to begin establishing the operational design domains (OODs) of AVs, which will be crucial in mitigating the risk that will arise during the interactions of different levels of AVs and humans. Preliminary results from Driver-In-the-Loop (DIL) experiments seem to suggest that increasing the level of automation might have some benefits for traffic as a whole but that lower-level AVs might led to some dangerous situations for human drivers. More human participants will be needed to verify these results but overall, this thesis managed to develop a feasible simulation framework that can be used for future human subject studies
