WP4 - Processes and Tools

Background
To meet future safety requirements, the automotive community is faced with a rapidly increasing demand for E/E architecture and a systems engineering process that fits to the needs of Integrated Safety Systems. WP4 is focused on the systems engineering process which has to be as uniform as possible and supported by cross-competitive and seamless tool chain. Efforts concentrate on a specific automotive tool environment which has to fit to the desired vehicle architecture which is defined by WP1 (Software) and WP2 (Hardware).

Main Objectives
From the engineering point of view, an Integrated Safety Systems (ISS) connects information regarding the vehicle surrounding to influence a hard real time chassis- or powertrain-control system, thus transforming a basic-functioncontrol-loop to an ISS-control-loop. While the engineering process for basic-function-control-loop systems is well understood, ISS-control-loop design requires new approaches w.r.t. development process and supporting tool chain.

Expected Outcome
The work in WP4 is expected to give the following results:

A software specific system engineering process framework (EASIS Engineering Process, EEP) shall be defined which fits to the needs of the automotive industry. This process will be based on requirements collected both within EASIS and with other IS Projects. Results from WP3 (Dependability) will be integrated in the EEP to secure that safety requirements are met.
It has been identified that the most crucial aspects of ISS (Integrated Safety System) must be analysed and tackled in the very early phases of development. Based on EAST-ADL framework, tool support for these phases will be identified. A tool chain recommendation for the development of ISS will be given.
In early phases of ISS development, model based methods are regarded as indispensable for the analysis of the interaction of ISS functions in order to identify and overcome safety critical parts. Tool support for this approach is partially present, but confidence is still not widespread. Based on an analysis of the IEC61508, means will be identified to improve confidence in model based techniques, thus facilitating future certification work.

Selected results of WP4 (EEP guidelines on process steps, tool recommendations) will be demonstrated in a validator (WP5).
