Battery management systems (BMSs) are essential in ensuring the safe and stable operation of lithium-ion batteries (LIBs) in electric vehicles (EVs). Accurate sensor signals, particularly voltage, current, and temperature sensor signals, are essential for a BMS to perform functions such as state estimation, balance control, and fault diagnosis. The smooth operation of a BMS depends primarily on sensor signals, which provide current, voltage, and temperature information to maintain the battery pack in a safe running state. However, sensor failures and inaccurate measurement data can easily occur because of external interference and complex operating conditions. Therefore, an investigation into the fault diagnosis of battery sensors and fault-tolerant control (FTC) is necessary to ensure the normal operation of a BMS. This paper analyzes the modes of sensor faults, fault diagnosis methods, and fault-tolerant control techniques. First, the different modes of sensor faults are analyzed, and mathematical expressions for these faults are provided. Second, diagnostic methods for sensor faults based on models, signal processing, and data-driven methods are analyzed in detail. Finally, FTC techniques are introduced to ensure stable sensor operation. Based on an analysis of the research status of sensor fault diagnosis, a new development direction for sensor fault diagnosis is proposed.

电池管理系统（bms）是保证电动汽车锂离子电池安全稳定运行的关键。准确的传感器信号，特别是电压、电流和温度传感器信号，对于BMS执行状态估计、平衡控制和故障诊断等功能至关重要。BMS的平稳运行主要依赖于传感器信号，传感器信号提供电流、电压和温度信息，以保持电池组处于安全运行状态。然而，由于外部干扰和复杂的操作条件，容易出现传感器故障和测量数据不准确。因此，研究电池传感器的故障诊断和容错控制（FTC）是保证BMS正常运行的必要手段。分析了传感器故障的类型、故障诊断方法和容错控制技术。首先，分析了传感器故障的不同类型，并给出了故障的数学表达式。其次，详细分析了基于模型、信号处理和数据驱动的传感器故障诊断方法。最后，介绍了FTC技术，以确保传感器的稳定运行。在分析传感器故障诊断研究现状的基础上，提出了传感器故障诊断的新发展方向。

Driving for a long time can lead to fatigue, which can affect information processing and decision-making, potentially threatening driving safety. By exploring the generation and variation patterns of driving fatigue and clarifying the application status of its detection and warning technology, traffic safety can be improved. In order to understand the research progress of driving fatigue, based on the Web of Science core database, this paper obtained 2127 English literature published from 1998 to 2023 (as of May 12, 2023), covering a total of 5963 authors and 6019 keywords, and the bibliometric tool VOSviewer and R-Bibliometrix are used to analyze the literatures. Firstly, the literature statistical analysis is carried out from annual distribution, country distribution, source journals, and core authors. Secondly, the research hotspots and trends are analyzed from keywords co-occurrence, high-impact literature, theme evolution, and development trends. Finally, the development trend of driving fatigue research is discussed. The result shows that the hotspots in the field of driving fatigue include driving fatigue detection, fatigue driving risk and fatigue research of professional drivers, driver alertness and coping strategies for driver fatigue, and driver fatigue under automatic driving. And the improvement of the accuracy and reliability of driving fatigue detection will be the difficult point to break through in the future. It is necessary to build a multi-disciplinary and meticulously quantified driving fatigue and its risk assessment system, and strengthen the control of fatigue risks. Research on intervention measures and education training for professional drivers needs to be deepened, while exploring the acceptance and compliance of intervention measures. Moreover, the evolution law and prevention strategies of driver fatigue under automatic conditions should be the focus of future research.

Particulate matter (PM) in outdoor air pollution is one of the most critical factors that cause serious health problems and even deaths. One significant source of these particles are non-exhaust emissions, which refer to pollutants that come from sources, like brake, tire, and road wear other than a vehicle's exhaust system. This review focuses on the presence of non-exhaust particles on pavement, encompassing their classification, composition, evaluation, and mitigation. Based on extensive literature, it can be concluded that the quantity of non-exhaust emissions is affected by a combination of complex factors, such as vehicle speed, tire type, and pavement material. Non-exhaust particles can be classified into organic, inorganic, and metal matter, each requiring a distinct analysis and detection method. The effective approaches to managing non-exhaust emissions include water cleaning, utilizing functional pavement materials, and applying chemical reagents to alleviate emission capacity. Finally, this review recommends future research directions such as combining tire-road simulation with environmental monitoring equipment, in the hope that this article will have a positive impact on the mitigation of non-exhaust emissions.

室外空气污染中的颗粒物（PM）是造成严重健康问题甚至死亡的最关键因素之一。这些颗粒的一个重要来源是非废气排放，它指的是来自其他来源的污染物，如刹车、轮胎和道路磨损，而不是车辆的排气系统。本文综述了路面上非废气颗粒的存在，包括它们的分类、组成、评估和缓解。基于大量的文献，可以得出结论，非废气排放量受到车辆速度、轮胎类型和路面材料等复杂因素的综合影响。非废气颗粒可分为有机、无机和金属物质，每种物质都需要不同的分析和检测方法。治理非废气排放的有效途径包括水清洁、使用功能性路面材料和使用化学试剂来减轻排放能力。最后，对今后的研究方向提出了建议，如将轮胎道路模拟与环境监测设备相结合，希望本文能对减缓非废气排放产生积极的影响。

Powered two-wheelers (PTWs) are considered as one of the risky means of transport as it is vulnerable to road crashes, which may lead to fatal injuries. Crash data revealed that the number of deaths caused by PTWs is significantly higher than any other road users. Literature reports that one of the major causes of high PTW crashes is the riding behavior of the users. Therefore, the present paper reviews existing literature related to factors affecting riding behavior. Several factors with different levels of influence on PTW riding behavior are explored in the paper. Further, safety strategies to improve PTW safety have been reported in the study by categorizing it based on risk factors, i.e., riding behavior, vehicle technology, and road infrastructure. The paper concludes with some of the major findings, i) riding behavior plays an essential role in improving PTW safety, ii) numerous research stated that riding behavior can be improved by enforcement and providing feedback about their riding behavior by profiling them into different categories, and iii) segregation of PTW traffic from other road users is reported to be an effective solution for increasing PTW safety in some developing countries. While a considerable amount of research related to riding behavior and PTW safety has been done, studies related to the impact of riding feedback on PTW riding behavior are scant. Further, it is suggested that future research should focus on the feasibility of advanced traffic management strategies, such as the segregation of PTWs from main traffic to reduce the conflict between vehicles.

动力两轮车（PTWs）被认为是危险的交通工具之一，因为它很容易发生道路交通事故，这可能导致致命的伤害。碰撞数据显示，由公路司机造成的死亡人数明显高于任何其他道路使用者。文献报道，高PTW崩溃的主要原因之一是用户的骑行行为。因此，本文对现有的有关骑乘行为影响因素的文献进行了综述。本文探讨了影响PTW行驶性能的几个不同程度的因素。此外，研究中还报告了提高PTW安全性的安全策略，该策略根据风险因素（即乘坐行为、车辆技术和道路基础设施）对其进行了分类。本文总结了一些主要发现，i)骑行行为在提高PTW安全性中起着至关重要的作用，ii)许多研究表明，骑行行为可以通过执法和通过将他们划分为不同类别来提供骑行行为的反馈来改善，iii)据报道，在一些发展中国家，将PTW交通与其他道路使用者隔离是提高PTW安全性的有效解决方案。虽然已有大量关于骑行行为和PTW安全性的研究，但关于骑行反馈对PTW骑行行为影响的研究却很少。此外，建议未来的研究重点应放在先进的交通管理策略的可行性上，例如将PTWs与主要交通隔离，以减少车辆之间的冲突。

Road networks are the backbone of urban life and significantly impact the sustainability of any country's infrastructure sector. Therefore, it is necessary to maintain the condition of roads and pavements through continuous monitoring and periodic maintenance in order to achieve the highest levels of service for road users and the sustainability of their use. Pavement is the main component of road networks, providing the highest degree of comfort to drivers and roadway users when it is appropriately designed and free from defects and cracks. More clearly, defects are one of the most important factors that reduce the operational life of roads and cause economic losses to road users by causing damage to their vehicles; moreover, the damaged pavement needs frequent and long maintenance that may also drain the resources of government institutions and transport agencies. Therefore, there is a crucial need for a monitoring and follow-up system for the condition of the roads in order to identify and treat defects quickly. This study used a vibration-based system to monitor pavement conditions on several roads with different gradients. A fully electric car was used to determine the vibration values, which indicate the degree of driving comfort, to determine the spread and behaviour of defects on the pavement at multiple locations on roads with different gradients. Also, a machine learning model was applied using a “decision tree” model to identify, classify and predict defects on the pavements. The results of this study indicated that pavement defects were more prevalent in the first and last quadrants of the high-slope roads compared to the low-slope roads. The prediction model achieved accuracy in predicting the performance of defects with a rate of 94% for roads with low gradients and 90% and 86% for roads with medium and high gradients, respectively.

道路网络是城市生活的支柱，对任何国家基础设施部门的可持续性都有重大影响。因此，有必要通过不断监测和定期维修来维持道路和路面的状况，以便为道路使用者提供最高水平的服务并使其持续使用。路面是道路网的主要组成部分，如果设计得当，没有缺陷和裂缝，可以为驾驶员和道路使用者提供最高程度的舒适性。更明显的是，缺陷是减少道路使用寿命的最重要因素之一，并通过造成车辆损坏给道路使用者造成经济损失；此外，损坏的路面需要经常和长时间的维护，这也可能耗尽政府机构和运输机构的资源。因此，迫切需要对道路状况进行监测和跟踪系统，以便迅速查明和处理缺陷。本研究使用基于振动的系统来监测几条不同坡度道路的路面状况。以全电动汽车为研究对象，通过振动值的确定来表征车辆的驾驶舒适度，从而确定缺陷在不同坡度路面上多个位置的分布和行为。此外，使用“决策树”模型应用机器学习模型来识别，分类和预测人行道上的缺陷。研究结果表明，与低坡度道路相比，高边坡道路的第一象限和最后象限路面缺陷更为普遍。预测模型对低坡度路面缺陷性能的预测准确率为94%，对中坡度路面缺陷性能的预测准确率为90%，对高坡度路面缺陷性能的预测准确率为86%。

Polyurethane (PU) as an alternative for petroleum asphalt binder in pavement engineering can not only prolong the service life of the pavement, but also enable the pavement to perform multiple functions such as drainage, noise reduction, snow melting, and ice melting, and flame retardancy, providing with economic, social and environmental benefits. PU is a kind of "wear-resistant rubber" with high strength and good wear resistance obtained by pre-polymerization of isocyanate and polyol. In this review, the design and preparation of PU and aggregates, i.e., PU mixture, were summarized, followed by the discussion of the strength, stiffness and durability of PU mixture. Numerous creative concepts of structure and mixture design of PU pavements were summarized, and PU dosage, the curing time, temperature, and compaction times were clarified in detail. Particularly, some successful applications including poroelastic road surface (PERS), PU porous mixture (PPM), PU rubber particle mixture (PRPM), and permeable PU stabilized recycled aggregate (PPSRA) were discussed. Special attention was given to the economic and environmental benefits of PU pavement. Overall, the PU pavement can achieve the much-needed functions of modern urban roads or highways, and prolong the service life of the pavement. However, more researches are needed to explore the design methods of PU mixture and improved its road performance. In addition, reducing the price of PU to reduce the construction cost of PU mixture was also a problem that needed to be solved.

聚氨酯（PU）作为石油沥青粘结剂在路面工程中的替代品，不仅可以延长路面的使用寿命，而且可以使路面具有排水、降噪、融雪融冰、阻燃等多种功能，具有经济效益、社会效益和环境效益。PU是一种强度高、耐磨性好的“耐磨橡胶”，由异氰酸酯和多元醇预聚合而成。本文综述了聚氨酯及其骨料，即聚氨酯混合料的设计和制备，并对聚氨酯混合料的强度、刚度和耐久性进行了讨论。总结了PU路面结构和配合比设计的诸多创新理念，并对PU用量、养护时间、温度、压实次数等进行了详细阐述。重点讨论了聚氨酯多孔混合料（PPM）、聚氨酯橡胶颗粒混合料（PRPM）和透水聚氨酯稳定再生骨料（PPSRA）等几种成功应用。特别注意聚氨酯路面的经济效益和环境效益。总体而言，聚氨酯路面可以实现现代城市道路或高速公路急需的功能，并延长路面的使用寿命。然而，聚氨酯混合料的设计方法和道路性能的提高还需要更多的研究。此外，降低PU的价格以降低PU混合料的施工成本也是一个需要解决的问题。

In recent years, research on the state of health (SOH) and remaining useful life (RUL) estimation methods for lithium-ion batteries has garnered significant attention in the new energy sector. Despite the substantial volume of annual publications, a systematic approach to quantifying and analyzing these contributions is lacking. This study focuses on selecting pertinent literature related to lithium-ion battery SOH and RUL estimation from CNKI and WOS databases, spanning January 2010 to December 2023. Employing bibliometric tools such as VOSviewer and CiteSpace, we conduct visual analyses to elucidate the current state, development trends, and research frontiers in this domain. Our examination encompasses scholarly activity, year-wise literature distribution, international collaboration networks, structural dissemination, and journal contributions. The findings indicate an upward trend in annual publication output, with China, the United States, the United Kingdom, and Canada at the forefront of collaborative research efforts. China is increasingly recognized as a pivotal hub for global scholarly partnerships. Notably, Harbin Institute of Technology, Beijing Institute of Technology, Chongqing University, Chinese Academy of Sciences, and Beijing Jiaotong University are the top institutions in China and the world in terms of publications. The Journal of Energy Storage emerges as a prominent periodical, acclaimed both domestically and internationally for its rigorous standards and high-quality articles. Based on the research content from CNKI and WOS, VOSviewer clusters the main research directions into three themes: aging mechanisms, SOH estimation methods, and RUL prediction methods. Keywords such as ‘online estimation’, ‘hybrid models’, and ‘artificial neural networks’ feature prominently, signaling a strong emphasis on artificial intelligence strategies. The study concludes with a prospective outlook on imminent research trajectories regarding the health and longevity estimations of lithium-ion batteries, highlighting the critical need for ongoing innovation and collaboration in this essential field.

近年来，锂离子电池健康状态（SOH）和剩余使用寿命（RUL）估算方法的研究在新能源领域备受关注。尽管年度出版物的数量很大，但缺乏对这些贡献进行量化和分析的系统方法。本研究从CNKI和WOS数据库中选取2010年1月至2023年12月的锂离子电池SOH和RUL估算相关文献。利用文献计量学工具，如VOSviewer和CiteSpace，我们进行可视化分析，阐明该领域的现状、发展趋势和研究前沿。我们的研究包括学术活动、年度文献分布、国际合作网络、结构传播和期刊贡献。研究结果表明，年度出版物产量呈上升趋势，中国、美国、英国和加拿大在合作研究方面走在前列。中国越来越被认为是全球学术合作的枢纽。值得注意的是，哈尔滨工业大学、北京工业大学、重庆大学、中国科学院和北京交通大学是中国和世界上发表论文最多的大学。《能源存储杂志》是一份杰出的期刊，因其严格的标准和高质量的文章而在国内外广受赞誉。基于CNKI和WOS的研究内容，VOSviewer将主要研究方向分为三个主题：老化机制、SOH估计方法和RUL预测方法。诸如“在线估计”、“混合模型”和“人工神经网络”等关键词占据突出地位，表明人工智能策略得到了强烈重视。该研究最后对锂离子电池的健康和寿命评估的未来研究轨迹进行了前瞻性展望，强调了在这一重要领域持续创新和合作的迫切需要。

Elevated pavement temperatures contribute to the urban heat island effect and pose a risk of thermal damage to pavement. Thus, regulating pavement temperature is paramount to ensure its longevity, enhance traffic safety, and preserve the environment. Phase change materials (PCMs) with the latent heat characteristic can store and release thermal energy via phase transitions. PCMs can effectively control pavement structure temperatures within a relatively narrow range, mitigating thermal stress on asphalt pavements. This research aims to explore the current status and emerging trends in PCM integrated pavement engineering (PCMIPE) using the CiteSpace visual analysis tool. Relevant publications were systematically curated from the Web of Science core database, spanning 2011 to 2023. Subsequently, the co-authorships network maps (country, institution, author), co-cited network maps (co-cited journals, authors, and references), and keyword co-occurrence network maps were constructed to analyze the principal contributions in the PCMIPE field comprehensively. This analysis provides an understanding of the field's strengths, research domains, and knowledge structure and identifies current research focal points and emerging frontiers. The findings reveal that research within the PCMIPE field is still in its early stages, with a predominant emphasis on material design and performance assessment. Additionally, future research is anticipated to expand into economic analyses and exploration of environmental effects when integrating PCMs into pavement engineering. Furthermore, there is an emerging interest in investigating the synergy of PCMs with other functional pavement technologies. These results underscore the potential of the PCMIPE field and emphasize the importance of future research endeavors.

路面温度升高会导致城市热岛效应，并对路面造成热损伤风险。因此，调节路面温度对于确保路面寿命、提高交通安全和保护环境至关重要。相变材料具有潜热特性，可以通过相变储存和释放热能。复合材料能有效地将路面结构温度控制在较窄的范围内，减轻沥青路面的热应力。本研究旨在利用CiteSpace可视化分析工具，探讨PCM综合路面工程（PCMIPE）的现状和发展趋势。从Web of Science核心数据库中系统地整理了相关出版物，时间跨度为2011年至2023年。随后，构建合作作者网络图（国家、机构、作者）、共被引网络图（共被引期刊、作者、参考文献）、关键词共现网络图，全面分析PCMIPE领域的主要贡献。该分析提供了对该领域优势、研究领域和知识结构的理解，并确定了当前的研究焦点和新兴前沿。研究结果表明，PCMIPE领域的研究仍处于早期阶段，主要侧重于材料设计和性能评估。此外，未来的研究预计将扩展到经济分析和环境影响的探索，当将pcm整合到路面工程中。此外，人们对研究pcm与其他功能性路面技术的协同作用越来越感兴趣。这些结果强调了PCMIPE领域的潜力，并强调了未来研究努力的重要性。
