Full title and description

ISO 23150:2023 — Road vehicles — Data communication between sensors and data fusion unit for automated driving functions — Logical interface. This international standard defines a logical, semantic interface for exchanging processed sensor information (object, feature and detection levels) between in-vehicle environmental perception sensors (radar, lidar, camera, ultrasonic, etc.) and a data-fusion unit that builds the surround model used by automated driving functions.

Abstract

This document is applicable to road vehicles with automated driving functions and specifies the logical interface between perception sensors and the fusion unit. It describes a modular, semantic representation providing object-level (moving/static/road objects), feature-level and detection-level information, plus supportive metadata. The standard explicitly excludes electrical/mechanical interface specifications and raw-data interfaces.

General information

• Status: Published.
• Publication date: May 2023.
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 43.040.15 (road vehicles — vehicle control systems).
• Edition / version: Edition 2 (2023).
• Number of pages: 344 pages (edition 2).

Scope

Specifies the logical (semantic and modular) interface for exchanging processed perception information between environmental sensors and a fusion unit in road vehicles with automated driving functions. The scope covers object, feature and detection representations and related metadata needed for scene interpretation. Excluded from scope are electrical and mechanical interface specifications and raw sensor data interfaces (the standard focuses on processed/perception-level information rather than raw streams).

Key topics and requirements

• Definition of a semantic, modular logical interface between sensors and the data-fusion unit.
• Standardized object-level representations (potentially moving objects, road objects, static objects) to support automated driving perception and decision functions.
• Support for feature-level and detection-level data where sensor-technology specifics matter (e.g., radar, lidar, camera detections and associated attributes).
• Metadata and supportive information for time-stamping, coordinate frames, confidence/uncertainty measures and sensor origin tracing.
• Explicit exclusion of electrical/mechanical specifications and raw-data interfaces — focus is on processed/perception outputs.

Typical use and users

Primary users include vehicle OEM architects, ADAS/AD system integrators, Tier‑1 sensor and fusion suppliers, sensor manufacturers (radar, lidar, camera), software developers for perception and fusion, testing and validation laboratories, and regulatory bodies or consortia defining interoperability for automated driving systems. The standard is used to harmonize data exchange expectations inside vehicles and to support multi-sensor fusion architectures.

Related standards

ISO 23150:2023 revises and replaces ISO 23150:2021 (the 2021 edition was withdrawn when the 2023 edition was published). In addition, ISO is developing multiple related parts/FDIS documents (e.g., ISO/FDIS 23150-1, -2, -11…-20) to extend the series into modular parts. Other adjacent standards often referenced in vehicle perception and ADAS system design include ISO 26262 (functional safety) and ISO/SAE 21434 (automotive cybersecurity).

FAQ

Q: What is this standard?

A: ISO 23150:2023 is an international standard specifying the logical (semantic) interface for exchanging processed perception data between environmental sensors and a data-fusion unit in road vehicles with automated driving functions.

Q: What does it cover?

A: It covers the modular semantic representation of perception outputs at object, feature and detection levels, including metadata (timestamps, coordinate frames, confidence measures) needed to build a surround model. It does not cover electrical/mechanical interfaces or raw sensor data streams.

Q: Who typically uses it?

A: Vehicle OEMs, Tier‑1 suppliers, sensor manufacturers, perception and fusion software developers, test labs and regulatory stakeholders who need a common, interoperable representation of perception outputs for AD/ADAS integration and validation.

Q: Is it current or superseded?

A: ISO 23150:2023 is the current published edition (May 2023). The previous 2021 edition was withdrawn when the 2023 edition was published. ISO has indicated further work on a multipart series (FDIS parts) under development to extend the standard.

Q: Is it part of a series?

A: Yes — ISO has planned and is developing multiple related parts (several ISO/FDIS 23150‑x parts) to split and extend the topic into modular documents covering additional interfaces and details.

Q: What are the key keywords?

A: Automated driving, sensor fusion, logical interface, perception, object-level data, lidar, radar, camera, semantic model, in-vehicle communication.
