QuaSAR@car stands for "Quantifying and predicting the effects of AUTOSAR meta-model changes and utilizing them in car projects" and it is a research projects which involves the followin  industrial and academic partners:

  • Volvo Car Group
  • Chalmers | University of Gothenburg
  • Volvo Group

QuaSAR@car project is also an associated project of the Software Center.

Project description
The AUTOSAR standard was introduced to make the development of electrical systems in modern cars more efficient in terms of cost and reuse. The constant evolution of the automotive domain and the AUTOSAR standard require methods and tools for efficient prediction of the effort needed to implement the changes. Furthermore OEMs need to predict what impact these changes may have on the existing car requirements so they can keep car development costs low.

The purpose of this project is to address the problem of efficient management of AUTOSAR evolution and its deployment in car projects by developing methods and tools for:

  • predicting the impact of AUTOSAR meta-model changes in terms of cost, rework and safety

  • automated consistency checks between car requirements and AUTOSAR meta-model changes

  • proposing solutions to the AUTOSAR meta-model based on the results from car projects

Project goals
The main goal of the project is to efficiently manage the evolution of the automotive software systems based on the evolution of the AUTOSAR standard. The short term objective is to develop methods and tools to significantly lower the cost of AUTOSAR adaptation due to automated change impact analyses. The long term objective is to enable faster and cheaper innovation cycles in car projects, increased reuse and more efficient development of AUTOSAR standard.
The project is funded by Volvo Car Group and Swedish Governmental Agency for Innovation Systems (VINNOVA) under the grant no. 2013-02630.
The QTool can be used for analysis of the evolution of automotive electrical systems with respect to their complexity and coupling properties.

The ARCA tool can be used for analysis of AUTOSAR meta-model changes and has the following functionalities:

  • Quantifying and presenting the changes between different versions of the AUTOSAR meta-model.

  • Presenting the results of a number of software metrics characterizing the AUTOSAR meta-model evolution.

  • Quantifying and presenting the changes caused by specific features of a new AUTOSAR release.

The SREA tool can be used for analysis of AUTOSAR requirements changes, in particular for quantifying and presenting the changes between different versions of AUTOSAR
