Management and Concepts for Functional Safety
The challenge in this project was to develop a 360° Lidar sensor, initially used as a prototype and not in a safety-critical context, to comply with ASIL B standards and transition it into safe series production. This involved adapting and continuously improving the development process according to ISO 26262, as well as equipping the product with a concept that met ASIL requirements. The development scope included concept creation, conducting a supporting analysis, and managing all safety activities within the project.
Solution Implemented
Functionally Safe 360° Lidar Sensor
Functionally Safe 360° Lidar Sensor
The first step towards a safe sensor involved informing all relevant domains about the functional safety requirements and documenting these in the development-supporting Safety Plan. Through continuous consulting with both the HW and SW development areas, as well as the testing and production departments, the process was progressively adapted and improved
During concept creation and analysis of the existing product, both the HW architecture and HW/SW implementation were adjusted to meet safety requirements. The preliminary creation of the system architecture and accompanying system analysis supported a systematic approach toward a safety-compliant Lidar sensor for the automotive sector.
