Hazard analysis is an essential activity in the development lifecycle of any safety-critical system. Understanding how sensitive they are to disturbances is 62262, for example, altering the input vector slightly should not result in a large step response although this is common. One of the main challenges faced by manufacturers is the difference in the terminologies used in the techniques and the standard. Machine learning enables many novel applications, and we want to use it also in safety-critical contexts.

Although the standard suggests using traditional hazard analysis techniques to identify hazards and to perform safety analyses, a literature review shows the limitations of these techniques to handle the increased complexity of modern vehicles, caused by the growing number of features added to them.

MacSphere: Using STPA in an ISO compliant process

Implications for Research Corroborates findings by Salay et al. Because of this distribution of functions, system safety depends more and more on the integrity of communication between ECUs.

TTTech Automotive, a TTTech subsidiary specialized in reliable automotive network solutions, has developed a reusable and modular safety layer that guarantees end-to-end communication integrity. The introduction of automotive thfsis ISO has garnered a lot of interest and the industry is moving towards following Thwsis compliant processes.

ML enables many novel applications, also in safety-critical contexts.

Just like many others, we are interested in knowing what parts of standards for development of safety-critical systems contradict the nature of machine learning. The final column shows the recommended adaptations based on our interviews.

Iso 26262 thesis

STPA, isp relatively novel hazard analysis technique, promises to overcome some of these limitations. In our preliminary study, we interviewed two experts on functional safety in the automotive domain, and asked them to comments on the findings from Salay et al.

Seven methods in ISO that needs to be adapted according to Salay et al. By properly understanding this, we could work from two directions to realize safe systems with machine learning features — we could develop learning behavior in a way to meet standards, and we could adapt standards iiso meet the nature of machine learning.

Our favorite study that does this is Salay et al. For example, a neural network is trained to create a mapping from an input to an output, but the corresponding requirements are not needed on a neuron level — instead we need requirements on the network architecture and the approach to training.

Safe Communication for Critical Systems Compliant with IEC 61508 and ISO 26262

Please use this identifier to cite or link to this item: Enabling Traceability Reuse for Impact Analyses: In conclusion, we determined that STPA can be used in an ISO compliant manner and also provided guidelines to fulfill any gaps identified.

Furthermore, it is fully compliant with the upcoming standard ISO To get access to the document please fill in the following form. It is important to note that we did not have to modify STPA but only augment it to achieve this. In case you wish to receive additional information, send an e-mail to products tttech. They concluded that seven methods need to be adapted, see the first two columns below.

At one of these workshops, we decided to conduct some interviews to capture thoughts by two experts in the field. TTX SafeCOM reduces development and certification costs by reusing a pre-certified common software component to ensure safe communication.

Due to the increasing number of safety-related functions 26226 automobiles, the amount of electronic control units in them is also rising. The solution is application-independent and can be applied universally. Costs for application development are lowered by offering the integration of a generic standard solution instead of an application-specific solution.
