“…Among them, Strobl et al [112] provided a thorough discussion of the advantages of automotive virtualization as a foundation for consolidating a wide range of ECUs into a few Domain Controller Units (DCUs). Safar et al [113] added a VP to the V-model of automotive software development as part of an improved methodology that allows SoC, ECU, and system-level verification and validation. It also includes the AUTOSAR software's fault injection capability and co-debugging mechanism.…”

Modern technological industries fused with the Internet-of-Things (IoT) have been advancing rapidly. The joint usage of several technologies has led to the reshaping of the modeling and simulation techniques into the virtualization of physical systems. Thus, the concept of virtual prototyping has emerged as a significant development in distributed IoT applications that includes early exploration, optimization, and security assessments. Several industries have been employing various types of prototyping e.g., virtual platforms, digital twins, and application-specific virtualization techniques, to achieve individual needs for development. In this survey, we clarify some of these concepts and the distinctions between them, provide a comprehensive overview of various prototyping technologies, and discuss how several virtualization technologies play a transformative role in the design and operation of intelligent cyber-physical systems.

“…Therefore, a safe, reliable and flexible test framework is required to accelerate the test process, reduce the time and effort, and cover the critical scenarios. Recently, virtual methods have contributed to improve the V-cycle development in the automotive industry in terms of verification and validation [ 15 ]. To overcome the limitations of real test drives, various virtual testing and validation methods, known as “X-in-the-loop” testing, have been introduced [ 16 ].…”

To validate safety-related automotive software systems, experimental tests are conducted at different stages of the V-model, which are referred as “X-in-the-loop (XIL) methods”. However, these methods have significant drawbacks in terms of cost, time, effort and effectiveness. In this study, based on hardware-in-the-loop (HIL) simulation and real-time fault injection (FI), a novel testing framework has been developed to validate system performance under critical abnormal situations during the development process. The developed framework provides an approach for the real-time analysis of system behavior under single and simultaneous sensor/actuator-related faults during virtual test drives without modeling effort for fault mode simulations. Unlike traditional methods, the faults are injected programmatically and the system architecture is ensured without modification to meet the real-time constraints. Moreover, a virtual environment is modeled with various environmental conditions, such as weather, traffic and roads. The validation results demonstrate the effectiveness of the proposed framework in a variety of driving scenarios. The evaluation results demonstrate that the system behavior via HIL simulation has a high accuracy compared to the non-real-time simulation method with an average relative error of 2.52. The comparative study with the state-of-the-art methods indicates that the proposed approach exhibits superior accuracy and capability. This, in turn, provides a safe, reliable and realistic environment for the real-time validation of complex automotive systems at a low cost, with minimal time and effort.

The education and training of electrical substations play an essential role for college students and engineers majoring in electrical engineering. However, to ensure the substation's safety production and equipment operation, it is difficult for personnel from external units to enter the site for learning. To overcome these limitations, this paper proposes a virtual interactive training technology method to author an interactive virtual maintenance education system (VMES) for electrical substations. The system aims to build a visual training and education platform for virtual substations to help learners master the station's equipment, operation, maintenance, evaluation, and other processes. Firstly, the system establishes a component‐level virtual interaction element to encapsulate an electrical substation virtual maintenance model that dynamically responds to user operations. The equipment structure and system environment are visually modeled using engineering modeling software. Secondly, a virtual interactive training system is created with the functions of 3D disassembly training, fault tree reliability evaluation, and AHP‐FCE maintenance assessment. Finally, through four operating systems, we evaluate the compatibility of the VMES, and we recruit learners to evaluate and discuss emerging and common educational models. The practical application results prove that the system can significantly improve students' learning efficiency and interest. Meanwhile, due to the increased number of interactive operations in VMES, participants can proficiently master the composition and working principles of equipment in substations, and cognitive load can be reduced.
