Dr. Bernd Relovsky, Daimler AG
ITEA 3 Launch Event Germany
Nuremberg, Germany, February 26th, 2014
FMI Vision and Objective
ITEA 2 Project MODELISAR | B. Relovsky, Daimler AG | ITEA 3 Launch Event Germany, Febr 26th, 20142
System function example:
Shifting time and quality
System example:
7G-TRONIC PLUS gearbox
Overall goal: Secure functionality of complex technical systems
• for customer comfort and safety
• at less costs
“Good products at little costs”
Aspired solution: Digital functional mock-ups substitute (late and expensive) physical mock-ups
• Challenge: Overcome domain barriers between
software, electrics, mechanics, etc. in existing
simulation tools & technologies
• Answer: Functional Mock-up Interface (FMI)
standard initiated 2007 by Daimler within ITEA 2

Steps towards Open FMI Standardas followed in MODELISAR
1. Industrial partners
• bring in requirements
from representative scenarios
2. Tool vendors and technology partners
• bring in technological know-how
• specify FMI standard proposal
• implement FMI specifications prototypically
3. Industrial partners
• validate FMI implementations
in their scenarios
4. Tool vendors*
• support and market the FMI
in their professional tools
5. Industrial partners*
• use FMI compatible tools

Interfaces and Use-case ScenariosThe four different interfaces of the FMI standard
have to provide the means for all kinds of scenarios

FMI Implementation
• Single component Functional Mockup Unit (FMU)
• Separation of
− Description of interface data (XML)
− Functionality (C code or binary)
• A FMU is a zipped file (*.fmu) containing the XML
description file and the implementation in source
or binary form
• Additional data and functionality can be included
• Multiple targets possible

A) BMW, Daimler and Ford started in Q2 2012 an initiative to establish FMI as the
standard for simulation model exchange between OEMs and suppliers
These OEMs as well as Chrysler, Fiat, GM, Jaguar Land Rover, Nissan, Renault,
Toyota and Volkswagen signed at GAAG conference in Oct 2012 a
commitment to support this initiative
Up to date, it was signed in addition by Audi, HKMC, Honda, Isuzu, PSA, Suzuki,
Tata, Volvo and Volvo Cars.

ITEA 2 Project MODELISAR | B. Relovsky, Daimler AG | ITEA 3 Launch Event Germany, Febr 26th, 20149
B) A Smart Systems Engineering project with OEMs, suppliers and IT tool
vendors started in October 2012 at ProSTEP iViP
Current results:
Recommendation for exchange of behavior models between 2 partners within a
collaborative development process (incl. reference process, use cases, description
templates for exchanged models and activities)
