The ISO/DIS 26262 standard on functional safety for road vehicles has a wide implication on the need for information exchange among partners in the automotive domain. As most development today is distributed among several companies and departments, it is important that all information exchange is precise enough to enable the OEM to take full responsibility of the entire functional safety. Still, there is also a need to protect Intellectual Property, because giving away detailed design information may jeopardize the commercial advantage for a company. The solution to this dilemma is a dedicated language for exchanging exactly the needed information in an unambiguous way. In ISO/DIS 26262 there is a standardized reference life cycle in which information should be generated and communicated in each phase. In this paper we show how dedicated language support can facilitate this in the distributed automotive industry structure of today. All phases are covered, but this paper has a special focus on the needs for the concept phase. The dedicated language support is a part of the EAST-ADL2 language. EASTADL2 is an AUTOSAR compliant architectural language covering the more abstract views of an automotive E/E system. It is an extendable modular language giving the possibility to add dedicated packages for special purposes. This paper describes the module of EAST-ADL2 dedicated for ISO/DIS 26262 support
