In the realm of intelligent vehicles, the collaborative driving mode between autonomous systems and human drivers is regarded as a long-term developmental trend. This paradigm integrates autonomous systems, drivers, and road environments, necessitating the design of a safe and efficient human-machine co-driving system due to its inherent complexity. This study delves into the interaction mechanisms of human-machine co-driving, clarifies the types of driver takeover scenarios, and thoroughly examines the multifaceted challenges encountered during system downgrade, including the accuracy of motion prediction, driving risk assessment, driver state monitoring, vehicle state information analysis, and the optimization of human-machine interaction interfaces. To address these challenges, we propose a series of design recommendations: enhancing the efficacy of autonomous driving systems through dimensionality reduction strategies;bolstering system robustness with redundant environmental perception;constructing advanced prediction and risk assessment models;establishing a comprehensive driver state evaluation system;optimizing vehicle state information analysis during takeover processes;and designing intuitive human-machine interaction interfaces. The aim is to develop a co-driving system that not only leverages the strengths of autonomous driving but also ensures the effective intervention of drivers when necessary, thereby providing robust theoretical support and practical guidance for the construction of safe, efficient, and intelligent autonomous driving human-machine collaborative systems. © 2024 IEEE.

In the automotive industry, the introduction of advanced AI technologies such as L3 autonomous driving is generally expected to significantly enhance traffic safety. However, the widespread adoption of these technologies in the actual market has encountered notable obstacles, with the core difficulty lying in successfully establishing user trust. To construct a trustworthy human-machine co-driving interaction system, we have conducted an in-depth analysis of existing research findings in the field of automation trust, considering them as important experiences and lessons learned from the application of AI technologies in autonomous vehicles. Based on these research findings in automation trust, we systematically defined the key attributes of autonomous driving trust and its primary influencing factors, and further constructed a conceptual model to comprehensively elucidate the underlying logic of the trust mechanism. On this foundation, we proposed a series of design suggestions aimed at enhancing trust in autonomous vehicles. Finally, we briefly introduced several design practice cases by automotive companies. This paper aims to provide invaluable references and guidance for researchers and designers of autonomous vehicles, helping them better address the critical challenge of trust establishment, and thereby facilitating the market penetration and industry development of autonomous driving technologies. © 2025 SPIE.

The high temperature and high speed reentry process of large spacecraft will lead to the disintegration of the spacecraft body and produce large debris. The separated debris interferes with each other seriously in the high Mach number incoming flow, forming a separated interference area in a large airspace, which has a great influence on the movement attitude and trajectory of the debris. Based on the research background of reentry disintegration of low-orbit spacecraft, this paper uses the Tiangong-1 virtual model to conduct three-dimensional numerical simulation of the separation process, and computationally simulates the complex flow field interference caused by explosive fragmentation and controlled separation under certain working conditions. In this paper, the problems of bending fracture and secondary disintegration of spacecraft components which may occur in the process of re-entry disintegration are studied. The variable computing domain method is used to perform aerodynamic numerical simulation of the separation interference problem in large airspace, and the three-dimensional trajectory prediction simulation of the separation component is realized over long time, long distance and wide basin.

When the spacecraft reenters the continuous flow area, the energy flow generated by high temperature and high speed causes the ablation explosion of the module. And under the control of human intervention, controlled separation of the re-entry capsule can be achieved under specific attitude and separation conditions. The spacecraft parts in the disintegration process are likely to produce bending, fracture and even collision, resulting in secondary or even multiple separations. Based on the virtual reentry model of low-orbit spacecraft, this paper uses the aerodynamic numerical simulation method to study the complex motion behaviors such as bending, fracture and secondary disintegration during the reentry disintegration process, and discusses the impact of the separation process on the spacecraft reentry trajectory. The following research topics are discussed in detail in this study: (1) Numerical simulation of debris trajectory in bending process;(2) The interaction of separated parts with different shapes in the process of movement after disintegration;(3) The problem that the disintegrated parts are separated twice or multiple times to generate complex shape fragments, which interfere with each other. (4) Numerical simulation of debris trajectory after multiple separations. Copyright © 2023 by the International Astronautical Federation (IAF). All rights reserved.

Amidst the pivotal transition of autonomous vehicles from Level 2 to Level 3, a fundamental paradigm shift occurs, moving from a shared human-machine control framework to a complete transfer of driving responsibilities. In this evolving context, the automated system assumes a primary role in executing driving tasks, while the driver transitions to a supervisory role, overseeing system behavior and intervening only when deemed necessary. This transition necessitates addressing complex challenges encompassing safety, liability, workload distribution, alongside fostering human-machine trust and enhancing system interpretability. To address these multifaceted challenges, we introduce a comprehensive human-machine shared driving interaction design strategy, referred to as the TSE design method. This strategy encapsulates the entire driving journey, commencing with pre-journey training and preparation, encompassing safe driving practices during the journey, and culminating in post-journey performance evaluation. Our primary emphasis lies in the intricate analysis of human-machine safety interaction strategies during the actual driving phase. Based on the current system status and road conditions, the automated system dynamically apportions driving tasks to the driver, considering factors such as the driver’s workload, engagement level, and the complexity of take-over tasks. Furthermore, we delve into the intersectional impact of various factors, including the driver’s mental model, attention allocation, situational awareness, human-machine trust, system transparency, and interpretive interfaces, on the overall performance of the human-machine shared driving system. To demonstrate the practical application of our design principles, we present concrete design exemplars derived from driver training sessions and take-over interaction design. These instances illustrate the effectiveness of our TSE design method in enhancing the safety, trust, and interpretability of the human-

This study delves into the bi-directional transparency interaction model (B-SAT) in the design of L3 autonomous driving. AS man-machine co-driving technology transitions to L3 autonomous driving, drivers may engage in non-driving tasks, leading to a decline in situation awareness (SA) and subsequent disengagement from the driving task, resulting in out-of-the-loop (OOTL) situations. Currently, the transparent interaction mode of existing autonomous system falls short of meeting the actual needs of the vehicle companies. To address this gap, the B-SAT interaction model was developed to design bi-directional transparency interaction information for L3 autonomous driving. B-SAT enhances the bi-directional transparency interaction design of L3 autonomous driving systems. It effectively tackles driver disengagement and trust issues in future L3 autonomous driving, thereby enhancing driving performance and the user experience of human-machine co-driving. Automotive designers and engineers can consider utilizing the B-SAT model for interaction design and user experience evaluation in L3 autonomous systems. © 2024 IEEE.

This article reports the corrosion behavior of 904L weldment in sulfuric acid as a strong corrosive media. The corrosion behavior was studied by total immersion tests and potentidynamic polarization test. Total immersion test has been conducted at different acid concentrations typically: 1, 2, 4, 6, 8 and 18.4 M at 25°C. The effect of temperature (25- 100°C) on the weight loss measurements of the alloy samples was followed in the 4 M acid solution. On the other hand, potentiodynamic polarization tests were conducted in 2,5, 8 and 18.4 M H2SO4 solution. The potentiodynamic polarization test was also conducted in the practically used leaching medium (2 M H2SO4 + 10% monazite). Results show that the weight loss increases with the increase of acid concentration and reaches its maximum at 4 M H2SO4 and then gradually decreases. Meanwhile, the rise in temperatures results in the increase of weight loss. Potentiodynamic polarization tests indicate that the 5 M acid solution gives the highest corrosion rate of 0.6399 mm/Y. The leaching medium shows relatively higher corrosion rate (0.124 mm/y) than the corresponding 2 M H2SO4 without monazite (0.01712 mm/y). © 2020 Trans Tech Publications Ltd, Switzerland.
