“…To reduce the wiring cost and weight, Brunner proposed the zone-based architecture, where in addition to functional domain clusters, components can be integrated based on their physical location in the vehicle [28]. In this way, the components around the vehicle are no longer classified by function, and automotive software and hardware platforms must be reconsidered.…”

“…The architecture is also beneficial for power supply. The area controller can provide both communication and power supply for corresponding peripheral components [28]. At present, different networks are applied for communication and power supply; however, the introduction of Ethernet can combine these networks and reduce cables and costs, providing greater flexibility in the network layout.…”

The automotive E/E architecture has undergone a paradigm shift in the past century. Particularly, the new requirements of automated driving are severely challenging the existing architecture, which has led to ongoing revolutionary innovation in E/E architecture. In this paper, we reviewed the evolution of E/E architecture and outlined the requirements-driven developments. We illustrated the stateof-the-art E/E architecture, including network topology, standards, simulator and software platform. We also discussed the next generation of E/E architecture from the perspective of different OEMs and suppliers. The analysis shows that software-defined, hierarchical, reconfigurable and customized E/E architecture is universally accepted. Furthermore, the automotive industry has been experiencing several transitions related to OEMs and suppliers. With the emergence and maturation of automated driving, we analyzed the new requirements on E/E architecture and proposed prospective development trends.

Automotive Architecture Topologies: Analysis for Safety-Critical Autonomous Vehicle Applications

Safety-critical systems such as Advanced Driving Assistance Systems and Autonomous Vehicles require redundancy to satisfy their safety requirements and to be classified as fail-operational. Introducing redundancy in a system with high data rates and processing requirements also has a great impact on architectural design decisions. The current self-driving vehicle prototypes do not use a standardized system architecture but base their design on existing vehicles and the available components. In this work, we provide a novel analysis framework that allows us to qualitatively and quantitatively evaluate an in-vehicle architecture topology and compare it with others. With this framework, we evaluate different variants of two common topologies: domain and zone-based architectures. Each topology is evaluated in terms of total cost, failure probability, total communication cable length, communication load distribution, and functional load distribution. We introduce redundancy in selected parts of the systems using our automated process provided in the framework, in a safety-oriented design process that enables the ISO26262 Automotive Safety Integrity Level decomposition technique. After every design step, the architecture is re-evaluated. The advantages and disadvantages of the different architecture variants are evaluated to guide the designer towards the choice of correct architecture, with a focus on the introduction of redundancy.

“…In the ZCA, a more centralized approach is being taken with the same goal of the DCA to minimize the ECU count in vehicles. Sensors and actuators communicate individually through their own dedicated communication bus to a very powerful centralized supervisory controller taking the decisions for each actuator/sensor function [48]. Furthermore, this architecture enables connectivity to external servers along with cloud computing and control of vehicles.…”

By increasing the electrified vehicles trend, it is crucial to have a survey of what is done before and what is the open challenge for improving this industry. Powertrain electrification has heightened the need for an energy management strategy, which has been a continuing concern in the development of electrified vehicles. An energy management control unit manages power flow between different energy sources in an electrified powertrain that directly affects vehicle performance. There are inadequate numbers of studies on the most recent energy management strategies, which are compatible with real-world scenarios. Intelligent energy management strategies requirements are discussed in detail, and it is categorized to principle-based, data-driven, and composite-based methods. Besides, enabling technologies for implementing an energy management system with a comparison of different controller chips are described to give readers an experimental view. Future trends and existing challenges are presented, which generate fresh insight into energy management strategies. Index Terms-data-driven methods, electric vehicles, intelligent energy management strategy, reinforcement learning, powertrain architecture.
