X-UWB – Extended Automotive UWB Platform – is a unified system architecture that significantly expands conventional UWB-based secure car access by enabling a wide range of additional interior and exterior sensing applications (e.g., presence detection, intrusion monitoring, and gesture-based functions) through activation of the UWB radar mode on the same hardware infrastructure.
The X-UWB platform is defined by the following core characteristics:

• One X-UWB node hardware for ranging AND radar – One physical UWB anchor
  infrastructure supports both UWB ranging and CIR-based sensing (UWB radar) without
  additional RF hardware.

• Modular building block architecture – X-UWB is structured as a
  scalable building block system consisting of clearly defined hardware, software, and feature
  layers. This modularization enables reuse across vehicle platforms and segments.
  • Hardware building blocks
  • Distributed UWB anchor nodes (UWB transceiver (incl. on-chip CPU) + antennas)
  • Central ECU or domain controller integration
  • Standardized communication interfaces (e.g., CAN, LIN, Ethernet)
• Software building blocks
  • Ranging engine (IEEE 802.15.4z secure ToF processing)
  • Radar/Sensing engine (CIR acquisition, preprocessing, feature extraction)
  • Security layer (authentication, distance bounding, anti-relay protection)
  • Fusion and decision layer (multilateration, zone classification, event logic)
• Feature building blocks
  • Secure access (Entry / Go / Phone-as-Key)
  • Interior sensing (Presence, CPD, Occupant Monitoring)
  • Exterior sensing (Kick Gesture, Motion Detection, Approach Detection)
  • Configuration-dependent advanced features (e.g., micro-movement detection)

• Scalable topology concept – Anchor placement and sensing coverage can be adapted to vehicle segment and feature requirements, enabling an optimized cost–feature ratio.

• Sensor consolidation capability – Multiple dedicated sensor modules (e.g., radar, ultrasonic, IR ToF, capacitive sensors) can be partially or fully consolidated onto the UWB platform.

• System-level simplification and cost advantages – Reduced sensor diversity lowers integration effort, ECU interfaces, wiring complexity, and overall E/E architectural fragmentation.

• Software-defined feature enablement – Functional expansion is achieved through software activation and configuration rather than additional hardware deployment.
