About the V2X On-Board Unit category

V2X Solutions V2X On-Board Unit
1

The V2X On-Board Unit (OBU) category comprises specialized vehicular communication hubs deployed in connected cars, electric vehicles (EVs), public transport, and emergency fleets. These units act as the core edge computing and telematics node for Intelligent Transportation Systems (ITS), enabling real-time data exchange to enhance road safety and traffic efficiency.

Key System Architecture & Features

  • Wireless & Direct Communications:

    • Integrated C-V2X (Cellular V2X via PC5 direct communication) and optional DSRC (IEEE 802.11p WAVE) for direct vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and vehicle-to-pedestrian (V2P) safety messaging.

    • Comprehensive wide-area connectivity via 5G / 4G-LTE cellular modems (Vehicle-to-Network / V2N) alongside Wi-Fi and Bluetooth for local diagnostics and hotspot capabilities.

  • Processing & Core Logic:

    • Powered by automotive-grade microprocessors (such as Arm-based heterogeneous SoCs or specialized telematics processors) capable of executing low-latency safety algorithms, trajectory predictions, and sensor fusion.

    • Dedicated real-time safety cores and MCU architecture handling deterministic vehicle telemetry.

  • Automotive Interfaces & Peripherals:

    • Multiple CAN-FD and Automotive Ethernet channels (e.g., 100BASE-T1) for seamless integration with in-vehicle electronic control units (ECUs) and sensor buses .

    • High-precision GNSS modules (GPS, GLONASS, Galileo, BeiDou) supporting real-time positioning and Network Time Protocol (NTP) synchronizatio n.

  • Security & Compliance:

    • Hardware security elements (such as integrated crypto-secure ICs or HSMs) supporting Public Key Infrastructure (PKI) and standards like ETSI TS 103 097 for secure, authenticated message exchan ge.

    • Built to withstand harsh automotive environments (typically IP67-rated enclosures, wide operating temperature ranges from $-40^\circ\text{C}$ to $+85^\circ\text{C}$, and compliance with strict EMI/EMC and vibration standar ds).
