A priority for Hybrid and Electric vehicles

 

Prototyping of control laws for electric motors

As a partner of auto-makers and equipment suppliers, IFP Energies nouvelles is enhancing its range of R&D services and products aimed at hybrid and electric vehicles.
In these types of vehicles, the specific characteristics of the powertrain demand specially adapted power electronics and engine control analysis and testing tools. The main objective is to prototype innovative control laws for electric motors. The tools developed by IFP Energies nouvelles in this context are:
 
- an electric SIL platform designed to prototype the control laws of different architectures of power converters and electric machines in realistic conditions, without the safety requirements linked to electrical power.
Electric SIL platform
Thanks to the electric SIL platform, the design of control laws is separated from the installation process. The tests are performed very early on in the development process. Integration and handling risks, along with development cycle repetitions, are kept to a minimum.
 
- an "open" inverter designed and produced by IFP Energies nouvelles in order to have access to power electronics capable of adapting to different types of electric motors. This tool is used to:
• pilot and characterize machines that do not have their own inverter (for example electric motors extracted from the vehicle)
• test and validate low-level control strategies for electric motors and adapt them to the requirements of hybrid and/or electric vehicles.
 
- a HIL bench used to study electric motors equipped with their power electronics and control, the other vehicle elements (IC engine, transmission, vehicle dynamics) being simulated in real time.
The purpose of this bench is to provide an experimental resource for the development of two modules:
• control of the electric motor of the hybrid vehicle
• distribution of power between the IC engine and the electric traction motor of the hybrid vehicle
It can therefore be used to evaluate the operation of the hybrid powertrain over a standard cycle in terms of fuel consumption or electrical energy consumption.

Technology focus
IFP Energies nouvelles thermodynamic tools for new-generation biofuel characterization

A good engine/fuel pair fit is a key R&D issue in terms of enhancing powertrain efficiency. Today, with the emergence of second-generation (and soon third-generation) bio-fuels, engine technologies require accurate developments in line with complex alternative fuel formulations. It is against this background that IFP Energies nouvelles has developed ReFGen, a tool able to calculate the physical properties of current and future fuels.
 
The ReFGen numerical generator uses the Carnot thermodynamic library, also designed by IFP Energies nouvelles. In particular, this specific library contains several complex equations of state (for instance Peng Robinson, CPA and SAFT) in order to predict the thermodynamic behavior of hydrocarbon mixtures, with ethanol or esters, for example.
 
The fuel's thermophysical properties generated by ReFGen are essential data for multidimensional combustion codes, such as IFP-C3D or AVBP, in order to predict the optimal mixture preparation with liquid fuel injections. Moreover, ReFGen results are also useful for simulation system tools such as the IFP-Engine library dedicated to combustion and engine simulation within the LMS Imagine.Lab AMESim simulation platform.
ReFGen is the latest numerical solution to be added to the range of engine simulation tools, along with existing 3D or 0D tools such as IFP-C3D and AMESim (IFP-Engine).

18th Aachener Kolloquium "Automobile and Engine Technology"

October 5-7, 2009
IFP Energies nouvelles was an exhibitor at the 18th Aachen Colloquium "Automobile and Engine Technology" with a booth dedicated to its latest developments in the field of vehicle electrification. It also presented the Mov'eo-DEGE platform research project aimed at pooling resources and innovation for the development of hybrid and electric vehicles. A demonstration of the HIL platform which enables real-time testing and validation of engine control systems was also much appreciated by visitors to the IFP Energies nouvelles booth.

SIA International Conference on "The Spark Ignition Engine of the Future: Facing the CO2 and electrification challenges”

December 2-3, 2009 - Strasbourg (France)
The latest SIA international Conference was organized in partnership with the University of Karlsruhe and INSA (National Institute of Applied Sciences) in Strasbourg. The event was an opportunity for experts from the automotive industry (OEMs and their suppliers) and oil industry, along with research laboratories and universities to exchange on the potential of spark ignition engines to achieve the low CO2 and electrification challenges of the future. Two papers were presented by IFP Energies nouvelles experts during the technical sessions:
- "Development and results of a new cylinder deactivation approach: the OVaLiD® concept", by C. Ternel, A. Pagot, P. Anselmi and X. Gautrot.
- "Pollutant emissions and fuel efficiency prediction for a downsized spark ignition engine using a 0-dimensional combustion model", by S. Richard, S. Bougrine, G. Font and F. Le Berr.

“Les Rencontres Scientifiques d'IFP Energies nouvelles”: E-COSM'09 - IFAC Workshop on Engine and Powertrain Control, Simulation and Modeling

30 November, 1-2 December 2009 - IFP Energies nouvelles/Rueil-Malmaison

E-COSM 09

E-COSM'09 examined the most recent developments in the fields of powertrain control modeling and simulation, focusing on the interplay between control design and validation on the one hand, and physical modeling and simulation on the other. As in the first edition, held in 2006, the aim was to bring researchers and users from the world of industry and academia together to share their industrial experience of "real-world" applications.
This year's edition was organized within the joint framework of "Les Rencontres Scientifiques d'IFP Energies nouvelles" series of international conferences and IFAC, the International Federation of Automatic Control. Nearly 50 contributions, including keynote, regular and invited session papers, were presented by a range of prominent scientists conducting research in automotive control and related fields.
The proceedings will be available online on the IFAC-PapersOnLine website and the best papers will be proposed for publication in IFAC journals and OGST - La Revue d'IFP Energies nouvelles.

Which Technologies to Diversify Transportation Fuels?

9 December, 2009
The IFP Energies nouvelles Sessions were held at IFP Energies nouvelles in Rueil-Malmaison on December 9, 2009 and presented the technologies needed to produce alternative transportation fuels from natural gas, coal, biomass and hydrogen. These sessions also addressed producer and user expectations and how they can be met. Presentations by major players and experts and a panel discussion gave participants a forward-looking vision of the main routes - both current and emerging - to alternative fuels.

Towards optimal combustion using CFD Analysis


"The target to increase the specific power output of turbocharged engines is a common development path towards upgrading of small engines throughout the automotive industry. For the combustion systems this requires enhancement of the charge motion and optimization of the mixture preparation. The expertise of IFP Energies nouvelles in this area helped to obtain a benchmark both for the current BMW series engines, as well as the simulation methods employed at BMW Powertrain. The seamless interaction of design, simulation and testing facilities at IFP Energies nouvelles provided a robust basis for the rapid investigation of design variants."
