What is ISO 23150 about ?
ISO 23150 is applicable to road vehicles with automated driving functions. ISO 23150 specifies the logical interface between in-vehicle environmental perception sensors (for example, radar, lidar, camera, ultrasonic) and the fusion unit which generates a surround model and interprets the scene around the vehicle based on the sensor data.
The interface is described in a modular and semantic representation and provides information on object level (for example, potentially moving objects, road objects, static objects) as well as information on feature and detection levels based on sensor technology-specific information. Further supportive information is available.
Note: ISO 23150 does not provide electrical and mechanical interface specifications. Raw data interfaces are also excluded.
Who is ISO 23150 for ?
ISO 23150 on data communication between sensors and data fusion unit for automated— logical interface is applicable to:
- Road vehicle manufacturers
- Automated driving functions developers
- Automotive engineers
- Vehicle testing facilities
Why should you use ISO 23150 ?
Highly automated driving (AD) functions for road vehicles require a situation awareness of the surroundings of the vehicle and a, preferably, comprehensive scene understanding. For the fast and reliable recognition of real-world objects, a sensor suite is necessary to provide information for the fusion unit.
ISO 23150 provides an overview of a logical interface. An interface is comprised of signals. Signals can be part of a logical signal group (LSG) for ease of logical grouping. The logical interface provides information from the sensor suite to the fusion unit.
To minimize the development efforts for the sensors and the fusion unit and to maximize the reusability of development and validation efforts for the different functions on the sensor and fusion unit side, a standardised logical interface layer between the sensor suite and the fusion unit is worthwhile and beneficial for both the sensor and the system supplier.
ISO 23150 gives three logical interface levels (detection-, feature- and object level). Detections, features, objects and supportive sensor information are the basis for a fusion unit.
