TL;DR: In this article , the authors proposed a gateway system for data-reduced communication between Ethernet and CAN systems with data reduction, where the gateway receives a compressed CAN message, decompresses it, and transmits it to the Ethernet network.
Abstract: Controller area network (CAN) data-reduction techniques have been developed to reduce CAN bus loads, which have increased due to the large number of electronic control units in modern automobiles. Automotive communication uses various in-vehicle network. These techniques make it possible that same information to be sent using less bandwidth. However, the existing CAN DR algorithms only consider the CAN network. Automotive communication uses various in-vehicle network (IVN) protocols such as CAN, FlexRay, and Ethernet. The use of DR techniques may cause compatibility issue in heterogenous IVNs. This paper proposes a gateway system for data-reduced communication between Ethernet and CAN systems with data-reduction. The proposed gateway system receives a compressed CAN message, decompresses it, and transmits it to the Ethernet network. Additionally, the gateway receives a normal Ethernet message, compresses it, and transmits it to the CAN protocol. An evaluation of the performance of the developed gateway system is also presented.

TL;DR: Based on the characteristics of in-vehicle Ethernet data frame structure, the authors proposes an information fault detection method through data shifting, detection, and policing, and verifies it by simulation with OMNET++ simulation system.
Abstract: With features such as the high data transfer rate of 1G/bps and strong compatibility, in-vehicle Ethernet can become the backbone network of next-generation in-vehicle bus network systems. Currently, in-vehicle Ethernet is mainly used in audio and video entertainment systems, to further improve the network security performance of in-vehicle Ethernet, the information security of the data layer and physical layer in the in-vehicle bus network system must be ensured. Based on the characteristics of in-vehicle Ethernet data frame structure, this paper introduces IEEE 802.1 Qci protocol, proposes an information fault detection method through data shifting, detection, and policing, and verifies it by simulation with OMNET++ simulation system. The experimental results show that the accuracy rate of in-vehicle Ethernet data during transmission can reach 99.61%, which further improves the network security performance of in-vehicle Ethernet.
TL;DR: In this article , the authors provide an overview of Ethernet-based in-car networking and discuss novel trends and future developments in automotive communications, as well as discuss the potential of Ethernet for automotive communications.
Abstract: Automated driving requires correct perception of the surrounding environment in any driving condition. To achieve this result, not only are many more sensors than in current Advanced Driver Assistant Systems (ADAS) needed, but such sensors are also of different types, such as radars, ultrasonic sensors, LiDARs, and video cameras. Given the high number of sensors and the bandwidth requirements of some of them, high-bandwidth automotive-grade networks are required. Ethernet technology is a suitable candidate, as it offers a broad selection of automotive-grade Ethernet physical layers, with transmission speeds ranging from 10 Mbps to 10 Gbps. In addition, the Time-Sensitive Networking (TSN) family of standards offers several features for Ethernet-based networks that are suitable for automotive communications, such as high reliability, bounded delays, support for scheduled traffic, etc. In this context, this paper provides an overview of Ethernet-based in-car networking and discusses novel trends and future developments in automotive communications.

Abstract: In some autonomous vehicle test scenarios, signal generators are required for generating the testing signals to simulate the real surrounding environment of the vehicle. This paper demonstrated a design scheme of multi-channel Ethernet system which can transmit the testing data through the multiple channels, a FPGA chip is used as the core device of the system, it can control the system to read the UDP frames stored in the two DDR4 DRAM chips integrated on board and processing them, by precisely time control, then the UDP data frames will be transmitted through corresponding Ethernet channel with a programmable time interval between the Ethernet channels, and each UDP frame transmission can be controlled. The result shows that each Ethernet channel of the system can transmit all the data correctly and timely, and its performance is quite stable and can be used as the multiple Ethernet signal generator in the autonomous vehicle testing scenarios.

TL;DR: In this article , the authors analyze the third generation of CAN, termed CAN XL, and study how interoperability can be ensured with Ethernet, and conclude that composite CAN XL-Ethernet networks are the key for getting the best of both worlds, not only in the automotive domain but also for sensing and control in scenarios like building automation, wired sensor networks and low-cost networked embedded systems with real-time constraints.
Abstract: New generation electrified and self-driving vehicles require much higher performance and flexibility for onboard digital communications than Controller Area Networks may offer. For this reason, automotive Ethernet is often regarded as the next de facto standard technology in these contexts, and by extension for networked embedded systems as well. However, an abrupt and drastic move from CAN to Ethernet is likely to cause further cost increases, which can be hardly tolerated by buyers. This paper analyzes the third generation of CAN, termed CAN XL, and studies how interoperability can be ensured with Ethernet. Likely, composite CAN XL-Ethernet networks are the key for getting the best of both worlds, not only in the automotive domain but also for sensing and control in scenarios like building automation, wired sensor networks, and low-cost networked embedded systems with real-time constraints.

Abstract: This paper reflects the content of the presentation “The Next Generation: Ethernet-APL for Safety Systems” at the NAMUR Annual General Meeting 2022. It deals with the use of the Ethernet Advanced Physical Layer (Ethernet-APL) in combination with the PROFINET/PROFIsafe protocol for safety applications. It describes the virtues of the digital communication between the field and safety system. In parallel the aspect of OT security for this use case is touched as well. The paper proposes a secure architecture, where safety- and non-safety field communications are still separated. At the end a set of requirements for the development of future APL devices is described.
