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)

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

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.

FMI-based Initiatives in Automotive Industry


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)

-> Ready for download in April
