This survey paper reviews recent trends in green vehicle electrification and digitalization, as part of a special section on “Energy Storage Systems and Power Conversion Electronics for E-Transportation and Smart Grid”, led by the authors. First, the energy demand and emissions of electric vehicles (EVs) are reviewed, including the analysis of the trends of battery technology and of the recharging issues considering the characteristics of the power grid. Solutions to integrate EV electricity demand in power grids are also proposed. Integrated electric/electronic (E/E) architectures for hybrid EVs (HEVs) and full EVs are discussed, detailing innovations emerging for all components (power converters, electric machines, batteries, and battery-management-systems). 48 V HEVs are emerging as the most promising solution for the short-term electrification of current vehicles based on internal combustion engines. The increased digitalization and connectivity of electrified cars is posing cyber-security issues that are discussed in detail, together with some countermeasures to mitigate them, thus tracing the path for future on-board computing and control platforms.

“…Recent studies on the future of the automotive and robotic industry predict that the borders between the ICT (Information and Communication Technology) industry and the consumer industry will blur, and that vehicles will become consumer-centric [13]. The huge market of 90-million vehicles sold worldwide per year is suited for integrated electronics and MEMS/MOEMS (micro electro/opto-electro mechanical systems) technologies and embedded control and signal processing tasks.…”

The special issue, “Sensors, Wireless Connectivity and Systems for Autonomous Vehicles and Smart Mobility” on MDPI Sensors presents 12 accepted papers, with authors from North America, Asia, Europe and Australia, related to the emerging trends in sensing and navigation systems (i.e., sensors plus related signal processing and understanding techniques in multi-agent and cooperating scenarios) for autonomous vehicles, including also unmanned aerial and underwater ones.

“…The use of vehicle-to-vehicle (V2V) communication is an integral part of intelligent transportation systems (ITSs) [1][2][3], and will be a core technology for high (L4, L5) autonomous driving levels. Since vehicles are becoming increasingly intelligent, they will be able to detect potential dangers, such crash risk, unsafe overtake, obstacles, improving collision avoidance and reducing fatalities.…”

Intelligent driving is a promising area for increased safety and comfort. Vehicular communication is an essential part to build such systems. This paper describes the modelling and the implementation of the IEEE 802.11p Physical (PHY) Layer to determine its reliability for vehicleto-everything (V2X), and particularly vehicle-to-vehicle (V2V), communications in the automotive field. A Matlab/ Simulink simulation is carried out to analyze not only the baseband processing of the transceiver, but also the RF hardware part, the physical channel in different operating conditions and environments, and all the main impairments and sources of interferences/noise. The transceiver model consists of three parts, the transmitter, the receiver and the intermediate channel block. The model can be used to explore the performance (bit-rate, successfully delivered packet-rate, latency,..) of V2X links in different conditions (line-of-sight, non-line-of-sight), and environments (urban, suburban, rural and highway), considering single-hop or multi-hop networking, and allowing also dynamically changing the channel characteristics, or even using different modulation and coding schemes and physical transmission parameters. To assess the proposed V2X simulation tool, the simulation results are compared to the theoretical performance and to experimental results, obtained using the NEC LinkBird-MX C2X device. The proposed simulation tool can be useful to study the impact of vehicles distance, speed and operating scenario on the reliability of the communication system, once fixed the hardware apparatus, or to specify the performance of the hardware components needed to ensure a given V2X communication performance.
