3 – MBSE maturity
Technical & Process Challenges
Technical challenges • Training of system engineers
• Increase confidence & quality of models
• Adapt model complexity to design challenge
• Develop & implement simulation methods
Process challenges • Management of model and data
• Management of modeling activities
• Common standards & rules across organization
• HR management

3 – MBSE maturity
Model exchange & Standards
Model exchange OEMs/Supplier
OEMS and suppliers are already exchanging
models. For the time being it’s ad-hoc
practices.
Key Success Factors
• Protection of Intellectual Property.
• Produce results that benefit both sides
Model exchange standard
Functional Mock-up Interface (FMI)
An emerging tool independent standard to
support both model exchange and co-
simulation of dynamic models.

3 – MBSE maturity
Some best practices to establish MBSE
Initial investment:
High initial investment (People, Organization, Tools)
Audacious goal while ensuring that each step has a positive ROI.
Re-Use
MBSE models are complex and take time to develop.
Modifying off the shelf model is faster than starting from scratch.
Human Resources:
Simulation is often a starting point for young engineers.
Is it also a recognized domain for a successful carrier path?

Performance, Fuel Consumption, Drivability & Shiftability Integrated approach to manage EU28 CO2 regulation
Simonluca Santoto – FIAT Chrysler Automotive
Performance, Fuel Consumption, Drivability & Shiftability
Automotive Vehicle Performance Conference. April 2015.
Goal: Target setting process for effective vehicle energy efficiency
Challenges:
• Fuel economy, performance and drivability are
inter-connected by complex trade-offs
• Deign of overall energy efficiency is a very
complex task
Use case example
• Heat recovery
2% CO2 reduction on NEDC

Multi-Attribute Balancing Fuel Consumption, Emissions, Drivability, NVH
Kazuhiko Gotoh – Toyota
SAE 2012. (2012-01-0946)
Use cases
• Fuel eco: different driving scenario
• Emission: prediction & conversion in cata.
• Drivability: Veh acc during tip in/out, gear shifting,
take-off
Emissions: Good correlation on 27 operating
points Fuel Eco: <1.5% error
Water T° quite representative Drivability: Good tendency
Goal: Reduce engine test and development time using Model Based Design in early
design stages
Sensitivity analysis
• Fuel control strategy (e.g.: baseline vs
stoichiometric control)
• Spark advance control
• Engine mount characteristics
• Driveline stiffness,…

Driveline Noise & Vibration Process to avoid judder
Yoichi Ooi, Hiroki Tsuji, Aisin AW Japan
VDI conference, June 2011
Trend:
• Early lock-up closing to reduce losses,
• Higher torques at lower engine speeds
• Increasing nbr. of vehicle variant
Potential issues
• Solving judder problems (10 & 40 Hz) at integration
phase.
Goal: Establish procedure to avoid judder
Implemented procedure
• Full vehicle modeling (not only gearbox, torque
converter & lock-up)
• Simulating several drive cycle with a range a vehicle
parameters
• Sensitivity analysis
• Foreseen and solve potential judder problems before
production & gearbox integration

Summary
• Vehicle-level functions drive the design process
• Innovation is at intersection of Mechanical & Controls
Engineering. This mandates Model Based System
Engineering (MBSE)
• MBSE starts to be standard practice in Europe/US and
is emerging in Asia
• Next challenges are related to the organization and
deployment of modeling activities into design process
