“…For instance, in case of failure in one zonal controller, another one could take over the functionality keeping the vehicle fully functional. At application level, a distributed SoA enables new functionalities like sharing services or applications between the vehicle and user smart-phones as explored in [83], or the interaction with the infrastructure for autonomous driving, as proposed in [84].…”

The automotive industry is undergoing a deep revolution. With the race towards autonomous driving, the amount of technologies, sensors and actuators that need to be integrated in the vehicle increases exponentially. This imposes new great challenges in the vehicle electric/electronic (E/E) architecture and, especially, in the In-Vehicle Network (IVN). In this work, we analyze the evolution of IVNs, and focus on the main network processing platform integrated in them: the Gateway (GW). We derive the requirements of Network Processing Platforms that need to be fulfilled by future GW controllers focusing on two perspectives: functional requirements and structural requirements. Functional requirements refer to the functionalities that need to be delivered by these network processing platforms. Structural requirements refer to design aspects which ensure the feasibility, usability and future evolution of the design. By focusing on the Network Processing architecture, we review the available options in the state of the art, both in industry and academia. We evaluate the strengths and weaknesses of each architecture in terms of the coverage provided for the functional and structural requirements. In our analysis, we detect a gap in this area: there is currently no architecture fulfilling all the requirements of future automotive GW controllers. In light of the available network processing architectures and the current technology landscape, we identify Hardware (HW) accelerators and custom processor design as a key differentiation factor which boosts the devices performance. From our perspective, this points to a need -and a research opportunity -to explore network processing architectures with a strong HW focus, unleashing the potential of next-generation network processors and supporting the demanding requirements of future autonomous and connected vehicles.

“…This means that the NGIVN allows to shift the processing of one VIU to another VIU, or even from one of the HPCs to a VIU in some cases. A distributed SoA enables new functionalities like sharing services or applications between the vehicle and user smartphones as explored in [71], or the interaction with the infrastructure for autonomous driving, as proposed in [72]. In terms of safety, this software defined approach is key in bringing new strategies to enable fault-tolerant behavior in the NGIVN.…”

Elastic Gateway Functional Safety Architecture and Deployment: A Case Study

The automotive industry has started its transformation towards Software-Defined Vehicles. This transformation is driven by the rise of the number of vehicle features, the high complexity of these features and their constraining availability requirements which affect all the players (Original Equipment Manufacturers, Tier1 and Tier2) of the sector. In the context of this transformation, our target, from functional safety point of view, is to, inter alia, provide an easy-to-use and safety-compliant execution and development flow and simplify the development and argumentation for safety by providing a) a pre-certified execution environment with safety design patterns and best-in-class safety measures and b) processes and tooling to minimize the system integrator's effort. Therefore, in this work we propose a top-down approach where we first define a New Generation In-Vehicle Network, NGIVN, capable of fulfilling the performance (e.g. high bandwidth, low end-2-end delay), safety-related availability (e.g. Autonomous Driving / Advanced Driver-Assistance Systems (AD/ADAS) up to SAE level 5) and safety requirements of modern vehicles. Also, we illustrate the advantages of this approach by deriving the functional and safety attributes of an Automotive Gateway SoC, named Elastic Gateway and destined to be part of the NGIVN. Through the deployment of the Elastic Gateway functional safety concept we demonstrate the flexibility provided by our approach with regards to the design of elements of the NGIVN.

“…Besides SOME/IP, there are many other experimental middleware solutions in the automotive domain and for cyberphysical systems [9]- [14], which mainly focus on implementing IP-based communications. In contrast, our work addresses a middleware approach that supports heterogeneous QoS requirements, which is indispensable for future backbone and zonal architectures in automotive networks.…”

Service-Oriented Architecture (SOA) is about to enter automotive networks based on the SOME/IP middleware and an Ethernet high-bandwidth communication layer. It promises to meet the growing demands on connectivity and flexibility for software components in modern cars. Largely heterogeneous service requirements and time-sensitive network functions make Quality-of-Service (QoS) agreements a vital building block within future automobiles. Existing middleware solutions, however, do not allow for a dynamic selection of QoS.This paper presents a service-oriented middleware for QoS aware communication in future cars. We contribute a protocol for dynamic QoS negotiation along with a multi-protocol stack, which supports the different communication classes as derived from a thorough requirements analysis. We validate the feasibility of our approach in a case study and evaluate its performance in a simulation model of a realistic in-car network. Our findings indicate that QoS aware communication can indeed meet the requirements, while the impact of the service negotiations and setup times of the network remain acceptable provided the crosstraffic during negotiations stays below 70% of the available bandwidth.
