„When we’re talking about highly automated driving, we are also talking about a shift from ‚Fail safe‘ to ‚Fail operation‘.“

This goal can’t be achieved by a one-channel-system and leads to a redundant system, using two ASIL (Automotive Safety Integrity Level) components. But as there is usually only one power generator within a car, a mixed ASIL-QM design is the result. Hence any potential negative impact of failure by a QM component for an ASIL component must be prevented.

The impact on product, production, processes and organizational implications is our next topic.
Dr. Karlheinz Morgenroth (Head of Functional Safety) and Bernd Schneider (Head of System Development), both from LEONI will shed some light for us.

Working for DAIMLER, Dr. Neckenich and his team have supported the development of the current standard KBL 2.4 and the soon to be released version 2.5.

One of the key goal was to ensure the quality of the delivered data. This should be guaranteed by the following three measures:

1. Schemas / content check
The standard makes important attributes mandatory and requires the correct use of names, part numbers and units. In addition a correct documentation of special use cases should also help other applications to understand the projects.

2. Visualization
At each time of the development a visualization is available. 2D sketches can be mapped with the 3D model and changes are highlighted automatically.

3. Validity / Technical Check
