ISO 23150-14:2026

Overview

ISO 23150-14:2026 is part of the ISO 23150 series, addressing the logical interface between sensors and the data fusion unit for automated driving functions in road vehicles. Specifically, this document establishes the technology-specific logical interfaces for ultrasonic sensors and sensor clusters, detailing their integration at the feature, advanced detection and detection level interfaces. It is intended for road vehicles equipped with automated driving functions and supports both individual sensors and sensor clusters.

This standard does not cover electrical or mechanical interface specifications, nor does it specify raw data interfaces. Instead, the focus is on the logical and semantic description needed for secure, efficient sensor data exchange within automated driving systems.

Key Topics

• Scope of Applicability

  • Logical interfaces for road vehicles equipped with automated/automated driving functions
  • Ultrasonic sensors and sensor clusters
  • Feature level, advanced detection level, and detection level interfaces
  • Excludes low-level electrical, mechanical, and raw data interface details

• Interface Types

  • Feature Level Interface (FLI): Logical structure and requirements for transmitting feature-based information from ultrasonic sensors, supporting dynamic or fixed sensor cluster arrangements
  • Detection Level Interface (DLI): Defines how detection information is communicated, such as the number of detections, status, reflectivity, and geometric positioning
  • Sensor Cluster Profiles: Accommodate both real and virtual sensor combinations within a cluster, allowing flexible deployment and integration

• Modular and Semantic Design

  • Based on generic interface specifications laid out in ISO 23150-1
  • Interfaces are modular, ensuring compatibility and scalability as part of broader automated driving architectures
