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.
