ISO 23150-11:2026

Overview

ISO 23150-11:2026, published by the International Organization for Standardization (ISO), is a key international standard focusing on the logical interfaces between radar sensors or sensor clusters and data fusion units in road vehicles with automated driving functions. This part of the ISO 23150 series specifies how radar sensor data is semantically modeled and communicated at the interface level, ensuring interoperability, consistency, and integration for advanced automotive applications.

The scope of ISO 23150-11:2026 is strictly limited to technology-specific logical data interfaces for radar, including feature level, advanced detection level, and detection level interfaces. It is important to note that this standard does not address electrical or mechanical interface details, nor does it cover raw radar data exchange.

Key Topics

• Technology-specific Logical Interfaces
  Defines structured, modular data exchange at various levels, specific to radar sensors and sensor clusters.
• Detection Level Interface (DLI)
  Central to this standard, the radar detection interface (RDI) establishes how detected objects and scenarios are logically represented for fusion and automated decision-making.
• Ambiguity Handling
  Supports detailed representations of radar ambiguities (e.g., range, velocity, angle) to enhance confidence in multi-sensor fusion systems.
• Data Structure and Profiling
  Specifies the use of unique identifiers, mode types, domains for resolution limits, and probability metrics, optimized for seamless sensor integration in vehicle perception systems.
• Interface Modularity
  The interfaces are designed for modular, semantic representation, facilitating scalability and adaptation to different radar technologies within the automated driving stack.

Applications

Automotive and Automated Driving

The standard is essential for:

• ADAS and Automated Vehicles
  Enables robust, interoperable communication between diverse radar sensor suites and the vehicle’s central data fusion or perception units, which is fundamental for Advanced Driver Assistance Systems (ADAS) and higher levels of driving automation.
• Sensor Fusion Architectures
  By establishing a harmonized logical layer, ISO 23150-11 aids in integrating radar with other sensors (Lidar, cameras, ultrasonic, etc.), allowing for richer, more accurate environmental modeling and decision-making.
• Development and Validation
  Provides a common reference point for vehicle manufacturers, Tier 1 suppliers, and technology providers when designing, testing, and validating automated driving functions that depend on radar-based perception.

System Interoperability

The adoption of this standard allows different components and systems-often from multiple suppliers-to communicate efficiently, minimizing integration effort and reducing the risk of misinterpretation of sensor data.

Related Standards

ISO 23150-11:2026 is one part of a broader family, facilitating logical sensor data exchange for automated driving:

• ISO 23150-1:2026 – General information and principles for logical interfaces
• ISO 23150-2 – Object level interfaces
• ISO 23150-12 – Lidar specific interfaces
• ISO 23150-13 – Camera specific interfaces
• ISO 23150-14 – Ultrasonic specific interfaces
• ISO 23150-15 – Microphone specific interfaces
• ISO 23150-20 – Supportive and sensor input interfaces

This alignment ensures that radar-specific logical interfaces can coexist and integrate with those from other sensor modalities, forming a standardized, multi-sensor framework for the future of automated road vehicles.

By implementing ISO 23150-11:2026, stakeholders in the automotive and mobility sectors can ensure reliable, future-proof sensor integration and contribute to the seamless development of safe, automated driving systems using advanced radar technology.
