Up to now, no standard for automotive lidar sensor assessment has existed. Now, a joint SAE-DIN standard, № 91471, is the first such standard to be published. It’s entitled Assessment Methodology for Automotive Lidar Sensors, and it provides common sensor specification and characterization guidelines and a common and application-relevant evaluation framework. The use cases are related to environmental sensing, not in-cabin sensing. The targets of this document are:
- to have a clear and generally accepted framework for specification and testing of automotive lidar sensors;
- to create an objective understanding of automotive lidar sensors for consumer groups and other stakeholders;
- to build a trusted basis for automakers for creating RFQs and introduction of the right product;
- to make lidar sensor selection and specification simpler and more efficient for automakers;
- to make lidar sensor development; testing, and specification easier for suppliers;
- to make the automotive lidar market more transparent; profitable; safe, and efficient, and
- to make lidar sensors more readily comparable with other technologies.
Like all other SAE and DIN standards, this document by itself carries no legal or regulatory force, and it cannot change any existing regulations. Any potential power in that realm of a standard such as this is as a resource for regulators to draw on when crafting regulations.
this specification is based on point cloud data to assess the detection capabilities of the technology. Its scope does not include perception software (object detection). It is based on seven static tests to measure 12 KPIs, using simple lambertian targets with different reflectivity.
