The new demands and expectations of customers and the standard ISO 26262 forces companies in the automotive sector to fast and flexibly develop innovative, yet functional safe products. The standard postulates the requirement to detect random electrical and electronical faults in the products. If such a fault is detected, the product must be brought into a safe state to prevent damage to the passengers and other traffic participants. To fulfill these requirements, it is necessary to define a transparent and traceable Automotive Safety Integrity Level (ASIL) classification at the beginning of the product development process, as well as to establish an exchange process for interfaces, data and functions across department and corporate boundaries. The ASIL defines the requirements for the functional safety. The methodology developed has the goal to support and solve three of the main issues regarding the development of mechatronic products in context of ISO 26262. Those issues are the definition of an ASIL based on the target market, the handling of interface data across the complete development chain as well as to ensure a traceable and continuous implementation and documentation of requirements. This work analyzes the factors influencing the ASIL, which in consequence allows the definition of those factors with respect to the specific target market. In the further course of the work, an IT architecture based on the hazard and risk analysis (created with the Failure Mode and Effects Analysis; abbr. FMEA) was developed and implemented. This IT concept transforms the FMEA data into a new, extended data model, which is capable of handling data across company boundaries. This enhanced and easily extendable data model can contain all relevant and important information and relationships, as well as the possibility to document the realization of requirements. The approach and the model were validated within a research project in the field of emobility. The validation process has shown that the centralization and transparency of the data leads to an accelerated product development and to a reduced number of faults, which itself leads to higher level of safety.
