“…In particular, networked channels and communication buses must be efficiently managed to prevent a single embedded system from saturating a common bus and stalling the entire system. To address this concern, Choi et al [71] propose technical solutions to meet the data transfer and latency requirements of ICPSs using a communication bus topology.…”

Intelligent vehicular cyber-physical systems (ICPSs) increase the reliability, efficiency and adaptability of urban mobility systems. Notably, ICPSs enable autonomous transportation in smart cities, exemplified by the emerging fields of self-driving cars and advanced air mobility. Nonetheless, the deployment of ICPSs raises legitimate concerns surrounding safety assurance, cybersecurity threats, communication reliability, and data management. Addressing these issues often necessitates specialised platforms to cater to the heterogeneity and complexity of ICPSs. To address this challenge, this paper presents a comprehensive CPS to explore, develop and test ICPSs and intelligent vehicular algorithms. A customisable embedded system is realised using a field programmable gate array, which is connected to a supervisory computer to enable networked operations and support advanced multi-agent algorithms. The platform remains compatible with multiple vehicular sensors, communication protocols and human–machine interfaces, essential for a vehicle to perceive its surroundings, communicate with collaborative systems, and interact with its occupants. The proposed CPS thereby offers a practical resource to advance ICPS development, comprehension, and experimentation in both educational and research settings. By bridging the gap between theory and practice, this tool empowers users to overcome the complexities of ICPSs and contribute to the emerging fields of autonomous transportation and intelligent vehicular systems.

“…After a series of verifications, the results showed that the proposed method has better performance than other traditional methods. Choi et al [20] proposed methods to improve the performance of IVNs based on the bus topology. Simulations showed that the methods can improve the data transmission speed and reduce the transmission delay.…”

The bus network is widely used in industrial automation and avionics systems due to its many advantages. Network reliability is an important indicator of the bus network design and analysis. However, the widely used reliability evaluation method is not capable of dealing with the bus network. In this paper, we model the bus network without redundancy and the bus network with redundancy, propose the algorithms to calculate the two-terminal reliability and the k-terminal reliability of the bus network with redundancy, and verify the effectiveness of the algorithms in three scenarios. The experimental results show that when the reliability of the link reaches 0.9, the two-terminal reliability of the bus network with redundancy of six terminal nodes, eight terminal nodes, and ten terminal nodes is 40.95%, 52.17%, and 61.26% higher than that of the bus network without redundancy, respectively; k-terminal reliability is 61.26%, 74.58%, and 83.32% higher than that of the bus network without redundancy, respectively. The bus network with redundancy increases the communication paths for data exchange between devices, and has higher reliability than the bus network without redundancy. The algorithms proposed in this paper provide an effective solution for the reliability evaluation of the bus network. It perfects the reliability evaluation system of the network with different topology architectures.INDEX TERMS Minimal path sets, minimal cut sets, reliability evaluation, Sum-of-Disjoint Products, the bus networks.

The evolution of autonomous vehicles (AVs) has captured widespread interest lately, offering prospects for enhanced road safety, alleviation of traffic congestion, and heightened fuel efficiency. The essential role of Controller Area Network (CAN) bus protocols in the operational integrity of AVs is undeniable. This research outlines the architecture of an elementary autonomous vehicle predicated on diverse CAN bus frameworks. We introduce a design that integrates a multiplexed CAN bus arrangement, fostering streamlined interactions among the AV's various subsystems. This design is inherently scalable, promoting ease of modification in step with evolving autonomous vehicular technologies. The paper delves into the intricacies encountered throughout the design phase and articulates the methodologies adopted to surmount these obstacles. Empirical simulations substantiate the efficacy of our design, underscoring its dependability and strength across a multitude of vehicular contexts. Fundamentally, this design lays the groundwork for the advancement of sophisticated AVs, thereby contributing to the realization of optimized vehicular ecosystems.
