Model-based systems engineering (MBSE) is considered an important approach for understanding multidomain fields and is widely used in complex systems such as aerospace. In this article, a detailed survey of MBSE literature was conducted from its commencement to the present trends through bibliometric analysis. Some bibliometric tools were used to implement a visual network analysis of MBSE-related manuscripts. The results of the bibliometric study revealed the interrelationship and distribution of researchers in multidomain fields. The authorized sources of MBSE papers were also assorted. The current practices of MBSE were analyzed. The future directions for MBSE based on the current practices were discussed. We found that MBSE's research has been conducted by many research teams with distinctive characteristics, and the top publishing sources in this field have emerged. Research on MBSE focuses on system engineering, languages, system of systems, and digitalization. The development of new technologies such as next-generation modeling languages is improving current practical problems. The findings of this study may help researchers gain a faster and more comprehensive understanding of the current and future developments in MBSE.

“…With the demands of SOTIF for autonomous vehicles, some SOTIF-related studies on automated driving functions have emerged. Different SOTIF analysis methods, which combined with system analysis theories such as Systems Theory Process Analysis (STPA) and Model-Based Systems Engineering (MBSE), were presented in [37][38][39][40], and these methods were applied to autonomousemergency braking (AEB) systems. Both [41] and [42] studied the SOTIF-related problems of lane-keeping assist (LKA) systems and proposed solutions.…”

The detection range and accuracy of light detection and ranging (LiDAR) systems are sensitive to variations in fog concentration, leading to the safety of the intended functionality-related (SOTIF-related) problems in the LiDAR-based fusion localization system (LMSFLS). However, due to the uncontrollable weather, it is almost impossible to quantitatively analyze the effects of fog on LMSFLS in a realistic environment. Therefore, in this study, we conduct a layered quantitative SOTIF analysis of the LMSFLS on foggy days using fog simulation. Based on the analysis results, we identify the component-level, system-level, and vehicle-level functional insufficiencies of the LMSFLS, the corresponding quantitative triggering conditions, and the potential SOTIF-related risks. To address the SOTIF-related risks, we propose a functional modification strategy that incorporates visibility recognition and a 3σ-criterion-based variance mismatch degree grading adaptive extended Kalman filter. The visibility of a scenario is recognized to judge whether the measurement information of the LiDAR odometry is disturbed by fog. Moreover, the proposed filter is adopted to fuse the abnormal measurement information of the LiDAR odometry with IMU and GNSS. Simulation results demonstrate that the proposed strategy can inhibit the divergence of the LMSFLS, improve the SOTIF of self-driving cars on foggy days, and accurately recognize the visibility of the scenarios.

“…Diese Tatsache wird in der zuvor angeführten Fachliteratur zur STPA (insbesondere [16,17]) grundsätzlich erläutert, jedoch in Publikationen über die Anwendung von Methoden der Gefährdungsanalyse häufig anders dargestellt. Beispiele für aktuelle Veröffentlichungen, die in ihren Ausführungen eindeutig suggerieren, STPA könne im Kontext des automatisierten Fahrens als Ansatz für die Gefährdungsidentifikation eingesetzt werden, sind [2,5,14,15].…”

Zusammenfassung Um bereits in der Konzeptphase autonomer Fahrzeuge einen fundierten Eindruck bestehender Risikopotenziale zu erhalten, werden im Zuge von deduktiven und induktiven SOTIF-Analysen mögliche auslösende Umstände für gefährliches Verhalten untersucht. In diesem Zusammenhang wird in der ISO 21448 die Durchführung einer systemtheoretischen Prozessanalyse (STPA) vorgeschlagen. In diesem Beitrag führen wir deutsche Terminologie für SOTIF-Betrachtungen ein und setzen uns im Zuge einer Anwendung kritisch mit der STPA-Theorie auseinander, wobei wir begleitend methodische Ergänzungen anregen.
