The number of embedded solution in the automotive industry is increasing. In the latest vehicles numerous functionalities (e.g. engine-control, break-system, ESP, navigation, power steering) are controlled by embedded electronic control systems. Because of the increasing number of interconnected systems the design complexity of the vehicles electronic system is also increased. Therefore the demand for standardized communication and standardized architecture in the automotive industry is significant. The AUTOSAR standard offers satisfactory solution for these demands.

The ThyssenKrupp manufactures steering systems with Electric Power Assist Steering (EPAS). Based on the previous demands ThyssenKrupp purposed to itself the utilization of the AUTOSAR standard their systems.

The conversion of the developed software’s architecture should be performed to introduce AUTOSAR standard.

During the preparation of the thesis my task was to determine the steps of the architecture conversion with contribution of my consultant at ThyssenKrupp. The implementation was performed in MATLAB Simulink/Targetlink environment.

The determined implementation method was the following: a software component should be prepared to be AUTOSAR compatible, and should be integrated into the prepared current software. During the integration the original modules with the same functionality should be eliminated. Comparative simulations should be performed to verify the successful integration. After a certain number of iterations, when the last original module is eliminated, the software’s architecture should meet the AUTOSAR standard.

During the preparation of the thesis my task was also to implement the first steps of the first software component’s integration.

The comparative simulations verified that the tasks assigned to me were successfully performed.
