Overview
ISO 23150-1:2026 defines general information and principles for the logical interface between environmental perception sensors and the data fusion unit in road vehicles equipped with automated driving functions. Developed by ISO as part of the broader ISO 23150 series, this standard provides guidance for establishing a consistent, modular, and semantic interface to facilitate efficient information exchange between vehicle sensors and the data fusion unit responsible for generating a dynamic surround model.
This first part of the series lays out foundational concepts and provides generic interface templates for different abstraction levels and sensor technologies. The document specifically addresses logical, not electrical or mechanical, interfaces and does not cover raw data interfaces.
Key Topics
- Logical Interface Layers: Description and structuring of interface layers, including detection, advanced detection, feature, and object levels, which support various stages of data processing for environmental perception in automated driving.
- Modular and Semantic Representation: Establishing a modular approach and semantic definitions for how sensor data should be structured and interpreted by the fusion unit.
- Abstraction Levels: Providing information on different levels of abstraction tailored to sensor technology, facilitating scalable integration and development for multiple types of sensors and functions.
- Generic Interface Templates: Templates for multiple interface levels to guide implementation-for example, signal grouping, profiles for road properties, object classification, and measurement status.
- Supportive and Input Interfaces: Guidance on interfaces that supply supporting information as well as those handling sensor input from in-vehicle networks, enhancing interoperability.
- Terminology and Definitions: Standardized vocabulary including terms like object, detection, feature, tracking, accuracy, and precision, supporting clear communication across suppliers and system developers.
Applications
ISO 23150-1:2026 is applicable in the design and development of automated and highly automated driving systems for road vehicles. Its primary practical benefits include:
- Interoperability and Integration: By providing general principles and templates for logical sensor-to-fusion interfaces, automotive suppliers and manufacturers can achieve more straightforward integration of diverse sensor systems into automated driving platforms.
- Scalability and Modularity: The modular approach allows the standard to accommodate future sensor technologies and evolving functional requirements in automated driving, supporting reusability and minimizing development effort.
- Vendor Neutrality: Standardized semantic interfaces ensure that components from various vendors can communicate seamlessly, fostering a competitive supplier landscape.
- Reduced Development Cost: Harmonizing communication protocols and abstraction levels reduces duplication of effort in sensor and algorithm development.
- Enhanced Scene Understanding: By guiding the fusion of comprehensive, multi-sensor input into a coherent surround model, the standard underpins safer and more reliable automated driving functions.
