ISO 23150-12:2026

Overview

ISO 23150-12:2026 defines the logical interface requirements for lidar sensors or sensor clusters used in automated driving (AD) functions in road vehicles. This standard specifically addresses the technology-specific logical interfaces for lidar, focusing on the detection level interface (DLI), as well as supporting the integration of lidar data into data fusion units. Importantly, this document does not address electrical or mechanical interfaces, nor does it include raw data interface specifications.

Developed by the International Organization for Standardization (ISO), ISO 23150-12:2026 belongs to the broader ISO 23150 series, which covers logical interfaces between various automotive sensor technologies and data fusion units. The document ensures semantic compatibility and modular integration of lidar-based perception in automated driving functions, enabling reliable environmental modelling and scene interpretation.

Key Topics

• Scope of Application

  • Road vehicles with automated driving (AD) functions leveraging lidar sensors or sensor clusters.
  • Interface definitions at the detection level, describing logical and semantic requirements for transmitting detection results from lidar sensors to data fusion units.

• Interface Levels

  • Feature Level Interface (FLI): Not defined for lidar in this document.
  • Advanced Detection Level Interface (ADLI): Not defined for lidar in this document.
  • Detection Level Interface (DLI): Main focus, defines how detection data is structured and communicated.

• Lidar Detection Interface Structure

  • Logical structure includes detection headers, detection entities, and profiles for organizing detection data.
  • Specifies key detection attributes such as existence probability, measurement time stamps, and positional data (radial distance, azimuth, elevation).

• Signal Groupings

  • Lidar detection entity data includes:
    • Status: General detection information.
    • Information: Lidar-specific detection aspects, e.g., reflectivity.
    • Position: Detection coordinates in the sensor’s frame.
    • Dynamics: Relative velocity and movement data.

• Profile and Optimization Options

  • Encourages optimization and extension through profiles for versioning, redundancy, and configuration of signal representation levels.

Applications

• Automated Driving Systems Integration

  • Standardizes the logical interface for lidar-equipped road vehicles, facilitating consistent integration of lidar-based detections into AD data fusion modules.
  • Enables interoperability of different equipment manufacturers’ lidar solutions within the same AD systems, reducing integration complexity.

• Data Fusion and Environmental Perception

  • Improves quality and reliability of environmental scene modeling by ensuring lidar detections are semantically well-defined and appropriately time-stamped.
  • Supports robust AD features such as object detection, free-space estimation, and obstacle avoidance.

• Future-Proofing AD Deployments

  • Provides a consistent, modular foundation for evolving sensor architectures in automated vehicles.
  • Enables easier system updates and component replacement due to standardized logical interface definitions.
