Purpose and goal
The main objective of the project is to enhance production of code for embedded control systems in vehicles in order to improve the performance of the underlying system: faster and safer operation, improved driving characteristics, driving automation, reduced energy consumption, reduced emission and reduced maintenance costs. Additionally, cost and time for the software development of these embedded systems shall be reduced. This is achieved by providing physics-based models in an automated way on electronic controllers (ECUs), microcontrollers, or other embedded systems.
Expected results and effects
The eFMI specification (FMI for embedded systems) enables transformation from, for example, Modelica to Flat Modelica (not completely finished; was intended to be eFMI equation code) or GALEC (eFMI algorithm code). This code can then be used for analysis or code generation that meets, for example, vehicle manufacturers´ eligibility requirements such as MISRA-C or AUTOSAR that can be used in vehicle electronic control units (ECUs). Since, for example, Modelica can be used as a source language, it is possible to simulate models under development and use the same model in production.
Planned approach and implementation
An objective in the project has been to standardize eFMI at a standardization body where the result can be developed even after the completion of EMPHYSIS; several of the participants in the project are active within the non-profit Modelica Association (MA) and it became natural to let eFMI become a project within MA. The various parts of eFMI were developed: the work on "algorithm code" started first; "equation code" started later when the scope of algorithm code was known. eFMI has now got a home at MA and eFMI equation code was (and is) developed as "Flat Modelica" within MA.
