Abstract
Complexity of automotive systems has increased in recent years. Nowadays cars are composed by a multitude of electrical and electronic components, sensors, computer resources and so on. The ISO 26262 is a standard that deals with the functional safety of the E/E (Electric and Electronic) components of road vehicles. The standard defines a functional safety development process model that automotive manufacturing must follow and document to achieve compliance with the standard, otherwise the manufactured product will not be suitable to run in commercial vehicles.Documenting the Software Architecture Design (SAD) is a challenging activity in industries for safety critical software systems. This is amplified when the software development must comply with the guidelines of the ISO 26262.This paper describes the results of a practical experience we conducted in collaboration with four international companies in the automotive domain. In this work we firstly performed a survey to understand the challenges that practitioners have to meet daily for developing SAD in compliance with the ISO 26262. In the subsequent step, we proposed a documentation template aiming at overcoming the challenges that emerged from the survey. The template was implemented in the Sparx Enterprise Architect modeling environment and was validated in an industrial case study that involved the same experts we enrolled in the survey. The results showed that the documentation template was judged as a valid means to produce SAD compliant with the ISO 26262 and to overcome the emerged challenges.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
