Power distribution solutions towards more efficiency

Image
CESA 2012 abstract

The well established 12V automotive power distribution system is facing some major changes. The main drivers for these changes are better energy efficiency and CO2-reduction. 12V Start-stop and 48V Mild-Hybrid solutions are seen as enablers for better efficiency.
With the innovative 12V start-stop functions, there are two new upcoming challenges to be solved, powernet stabilization and increased activation cycles.
The presentation will show semiconductor solutions for powernet stabilization, like dual battery switches, as well as solutions for replacing mechanical relays. Special interest is here also given to electronic fuse function, weight reduction by improved wire harness and a more flexible power distribution partitioning, as well as a reduction of electric power losses.
Finally the presentation will cover the 48V powernet requirements for semiconductors in Mild-Hybrid systems. Different system architectures will be discussed with their specific application …

Trends and Innovations in Safety Domain Architecture

Image
CESA 2012 abstract
Since years the demand for Driver Assistant Systems is continuously growing. Forward looking camera and radar applications are gaining popularity. Not only in the luxury car segment, but also in mid end car segments and migrating further into low end cars. In addition the merge of active and passive safety applications towards cognitive safety is progressing rapidly, supported by upcoming changes in the safety rating of cars. Additional radar and camera sensors are going to be equipped around the car for side and rear looking applications migrating towards 360 degree environmental sensing. Taking advanced development programs at vehicle manufacturer into consideration first semi autonomous driving applications can be expected within this decade.
All these trends will lead to a change in the safety electronic architecture.

Developing embedded user experiences - challenges and success factors in automotive environment.

Image
CESA 2012 abstract

Automotive product development is based on proven processes and development time that allows carmakers to respond to drivers needs in regards to quality, feature availability and look and feel of the device in the car.
When talking about user experience, driver’s expectations are influenced by consumer electronic devices, from interaction point of view (speech and/or gesture recognition) as well as content (graphic attractiveness, apps). Drivers are expecting the same seamless, simple, easy to use phone and tablet features in their car, while still requiring automotive quality in term of system stability, low driver distraction and updateability during automotive life-time.
With over a decade of experience in developing multimodal HMI, EB GUIDE – industry recognized HMI development products suite and speech dialog platform - has been proved reliable in more than a million vehicles on the road and in the upcoming year more vehicles will come to market using the EB GU…

Join the CESA Congress VIP Business Tour

Image
In partnership with the SIA, the Paris Region Economic Development Agency is organising the CESA Congress VIP Business Tour of 3 of the Paris region's most innovative locations for new mobility. The tour is scheduled on Monday, December 3rd.
Here is the agenda :
- 11.30 am to 1 pm : Welcome lunch at Paris Charles-de-Gaulle Airport.
- 2 pm to 3.15 pm : Visit of the Autolib operational centre.
Autolib is the first public-private service plan with more than 1,700 electric vehicles to be developed in a large European metropolis. It enables Paris Region inhabitants to rent electric cars for a few hours from interactive terminals located in the streets. Thanks to the VIP Business Tour, you will have the unique opportunity to visit Autolib's hub in Vaucresson and to experiment the electric Blue cars !
- 3.45 pm to 4.45 pm : Visit of the command post of the recently completed A86 motorway tunnel.
This location demonstrates how an information technology software system is used to mana…

The thermal management of electrified vehicles

Image
CESA abstract

When running on pure electric mode, electrified vehicles offer a very efficient energy conversion. Less than 3 kW in average is needed to drive an EV over an urban cruise. Consequently, the management of additional power demands of thermal functions, e.g. the cooling or the heating of the vehicle passenger cabin, or that of battery and power electronics, has a major impact on the overall vehicle power balance. A new system approach for thermal management, combining an innovative architecture, dedicated technologies and relevant control strategy, becomes decisive to offer a significant cruising range, secure the battery life time and also ensure quick engine response.
Within the scope of Vega/Thop, a cooperative project including six partners (Valeo, Renault, Saint Gobain Sekurit, Hutchinson, INSA/Cethil, LINC) funded by Ademe, a new thermal architecture was designed, prototyped and tested on benches and lab cars in order to assess the potential of such innovative therm…

Individual E-Mobility Solutions for Automotive and Off-Highway Applications – A System View by Bosch

Image
CESA 2012 abstract
Only a couple of years ago there were many doubts on a possible implementation and realization of hybrid and electric vehicles as an alternative for vehicles with an ICE powertrain.
Today we are in the position to see this differently. “The future automotive powertrain will be electric” is a prognosis of Bosch. The conversion of the powertrain to be electric assisted or become all electric was pushed through significant development effort over the last couple of years.
Today we see the hybrid technology being used in many different platforms of almost any OEM and the first all electric vehicles are available from series production. But the electric powertrain is not only revolutionizing the automotive industry.
At Bosch Engineering we are getting more and more requests for hybrid and electric powertrain solutions for off-highway applications. This includes for example fork lift trucks, municipal multi-purpose carriers, and also marine applications. These applicatio…

High performance magnets: which properties? which prospects?

Image
CESA 2012 abstract
High performance permanent magnets are a vital component of today’s clean energy technologies (e.g. hybrid vehicles, wind turbines) as well as many consumer appliances and accessories. The recent pricing pressure on the raw materials of rare earth based magnets, owing to the near monopoly of Chinese production of rare earth metals, has driven renewed interest in the study of permanent magnets.
In this paper we will recall the fundamentals of permanent magnetism, and outline the essential link between extrinsic properties and microstructure. We will describe the evolution in the properties of permanent magnets over the last century, linking the spectacular improvements achieved with the discovery of new phases and the development of improved processing.
We will explain the present dependence on the use of heavy rare earth elements such as Dy and Tb, in the production of Nd-Fe-B based magnets suitable for operation at the relatively high working temperatures of the m…

Faurecia will talk about the smart seat at CESA 2012

Image
CESA 2012 abstract
Many comfort functions can be embedded in an automotive seat. These include basic postural comfort (cushion length, height, and tilt), advanced comfort (lumbar support, headrest adjustment, shoulder adjustment), climatic management (heating and ventilation), and wellness features (e.g. customized massage therapies or dynamic adjustments according to occupant status or to driving conditions). All those functions represent a huge amount of possible combinations of configurations and command executions, while they are not at all customizable along the time by the users (generally, just a few have programmable fixed alternatives by default).
In order to reduce the complexity of seat control for the end-user, and enable the possibility of customization, Faurecia has developed a new concept for automated seat adjustment, positioning and comfort features settings that takes out the guesswork to properly adjust the seat, while providing the end-user a powerful tool to per…
