With the rapid development of autonomous vehicles,more and more functions and computing requirements have led to the continuous centralization in the topology of electrical and electronic(E/E)architectures.While certain Tier1 suppliers,such as BOSCH,have previously proposed a serial roadmap for E/E architecture development,implemented since 2015 with significant contributions to the automotive industry,lingering misconceptions and queries persist in actual engineering processes.Notably,there are concerns regarding the perspective of zone-oriented E/E architectures,characterized by zonal concentration,as successors to domain-oriented E/E architectures,known for functional concentration.Addressing these misconceptions and queries,this study introduces a novel parallel roadmap for E/E architecture development,concurrently evaluating domain-oriented and zone-oriented schemes.Furthermore,the study explores hybrid E/E architectures,amalgamating features from both paradigms.To align with the evolution of E/E architectures,networking technologies must adapt correspondingly.The networking mechanisms pivotal in E/E architecture design are comprehensively discussed.Additionally,the study delves into modeling and verification tools pertinent to E/E architecture topologies.In conclusion,the paper outlines existing challenges and unresolved queries in this domain.

With the continuous development of automotive intelligent networking and autonomous driving technologies,the number of in-vehicle electronic systems and applications is increasing rapidly.This change increases the amount of data to be transmitted in the vehicle and puts forward further requirements of higher speed and safety for in-vehicle communication.Traditional vehicle bus technologies are no longer sufficient to meet today’s high-speed transmission requirements,in which copper cables are used extensively,resulting in serious electromagnetic interference(EMI).Vehicle optical fiber communication technology,besides greatly improving the data transmission rate,has the advantages of anti-EMI,reducing cable space and vehicle mass.This paper first presents the motivation of applying vehicle optical fiber communication technology and reviews the development history of vehicle optical fiber communication technology.Then,the paper researches the devel-opment trend of automotive electrical and electronic architecture(EEA),from distributed EEA to domain centralized EEA and zone-oriented EEA.Based on the discussion of the development trend of automotive EEA,an EEA based on vehicle optical fiber communication technology is proposed.Finally,the key points and future directions of vehicle optical fiber communication technology research are highlighted,including vehicle multi-mode optical fiber technology,vehicle optical fiber network protocol,and topology.

Developing new energy vehicles has been a worldwide consensus,and developing new energy vehicles characterized by pure electric drive has been China's national strategy.After more than 20 years of high-quality development of China's electric vehicles(EVs),a technological R&D layout of“Three Verticals and Three Horizontals”has been created,and technological advantages have been accumulated.As a result,China's new energy vehicle market has ranked first in the world since 2015.To systematically solve the key problems of battery electric vehicles(BEVs)such as“driving range anxiety,long battery charging time,and driving safety hazards”,China took the lead in putting forward a“system engineering-based technology system architecture for BEVs”and clarifying its connotation.This paper analyzes the research status and progress of the three core components of this architecture,namely,“BEV platform,charging/swapping station,and real-time operation monitoring platform”,and their key technological points.The three major demonstration projects of the 2008 Beijing Olympic Games,the 2022 Beijing Winter Olympics,and the intelligent and connected autonomous battery electric bus project are discussed to specify the applications of BEVs in China.The key research directions for upgrading BEV technologies remain to be further improving the vehicle-level all-climate environmental adaptability and all-day safety of BEVs,systematically solving the charging problem of BEVs and improving their application convenience,and safeguarding safety with early warning and implementing active/passive safety protection for the whole life cycle of power batteries on the basis of BEVs'operation big data.BEVs have acquired new technological features such as intelligent and networked technology empowerment,extensive integration of control-by-wire systems,a platform of chassis hardware,and modularization of functional software.

Electronic skin(e-skin),a new generation of flexible electronics,has drawn interest in soft robotics,artificial intelligence,and biomedical devices.However,most existing e-skins involve complex preparation procedures and are characterized by singlesensing capability and insufficient scalability.Here,we report on a one-step strategy in which a thermionic source is used for the in situ molecularization of bacterial cellulose polymeric fibers into molecular chains,controllably constructing an ionogel with a scalable mode for e-skin.The synergistic effect of a molecular-scale hydrogen bond interweaving network and a nanoscale fiber skeleton confers a robust tensile strength(up to 7.8 MPa)and high ionic conductivity(up to 62.58 mS/cm)on the as-developed ionogel.Inspired by the tongue to engineer the perceptual patterns in this ionogel,we present a smart e-skin with the perfect combination of excellent ion transport and discriminability,showing six stimulating responses to pressure,touch,temperature,humidity,magnetic force,and even astringency.This study proposes a simple,efficient,controllable,and sustainable approach toward a low-carbon,versatile,and scalable e-skin design and structure-performance development.

High Technology Letters 2010年第1期16卷 90-93页

作者：孟祥 cao wanke Lin Cheng Sun Tielei National Engineering Laboratory for Electric Vehicle Beijing Institute of Technology Beijing 100081 P. R. China

Safety-critical applications such as the independently driving systems of electric vehicle (EV) require a high degree of reliability. The controller area network (CAN) is used extensively in the control sectors. A new real-time and reliable scheduling algorithm based on time-triggered scheduler with a focus on the CAN-based distributed control systems for independently driving EV is exploited. A distributed control network model for a dual-wheel independently driving EV is established. The timing and reliability analysis in the worst case with the algorithm is used to evaluate the predictability and dependability and the simulation based on the algorithm with CANoe software is designed. The results indicate the algorithm is more predicable and dependable. © by High Technology Letters Press.

车载电子电气架构的网络架构深刻影响智能网联车辆的通信安全性和确定性。针对面向时间敏感网络(TSN)的区域-功能域电子电气架构,本文首次建立了以端口数均匀、负载均衡和信息流端到端延时最低为优化目标的网络架构多目标优化框架。通过求解TSN流量调度问题获得信息流延时,将流量调度抽象为周期性车间作业调度问题(JSP),提出适用于流量调度的多种群遗传算法(MPGA),相比于传统遗传算法求解效果提高16%。为了快速求解多目标优化问题,设计了改进的快速非支配排序遗传算法(NSGA-II),通过引入迭代因子和拥挤因子对算法进行自适应交叉变异概率改进,优化效率提高了25%。仿真验证了多目标优化框架的有效性并为面向TSN的车载以太网网络架构优化提供了一种设计思路。

为解决电控自动变速器故障诊断和维修问题,建立了基于CAN总线和PSA(PCA-subtractive clustering-ANFIS)模型的自动变速器故障在线诊断系统。通过CAN总线实时采集变速器控制单元各传感器状态数据作为诊断样本,利用主成分分析(PCA)实现输入变量降维和去相关,应用减法聚类(subtractive clustering)方法生成初始模糊推理结构,并以此建立自适应模糊神经网络(ANFIS)故障诊断模型。仿真结果表明,结合CAN总线网络应用的PSA故障诊断模型能够准确地诊断出变速器的故障,其拟合能力及收敛速度均优于PCA-BP网络模型。
