CESA abstract : Voltage Classes for Electric Mobility (Delphi)

Electric Mobility is a dynamic field of development. New technologies stand alongside traditionally reliable approaches to electrical engineering and electronics and the system, which connects them to standard international combustion engine technology.

Today, many different voltages are used in electric and hybrid vehicles and it is difficult to understand the differences, the impact on component costs, on power electronics and on safety.

This presentation is the summary of a work performed at the German ZVEI providing an overview on the current state of technology and standardization of relevant voltage classes. The work has had as objective to support professionals and interested stakeholders in development, technology, production and repair service dealing with powertrain electrification.

Working groups and development teams involved in component specific activities in some vehicle areas are also given the opportunity to expand their knowledge from an overall system persepective.

Audi RS 7 concept taken to the limit with no driver at Hockenheim

At the DTM season finale, last week end in Germany, the Audi RS 7 piloted driving concept completed a lap on the Grand Prix track in Hockenheim – at racing speed, without a driver. It took just slightly over two minutes to complete a lap on the Grand Prix track, piloted with high precision and accuracy to within centimeters.

Check out the video :

For orientation on the track, the technology pioneer uses specially corrected GPS signals. This GPS data is transmitted to the vehicle via WiFi according to the automotive standard and redundantly via high-frequency radio.

In parallel to this, 3D cameras in the car film the track, and a computer program compares the cameras’ image information against a data set stored on board. This is what makes it possible for the technology pioneer to orient itself on the track within centimeters.

Piloted driving is one of the most important development fields at Audi: The first successful developments were achieved ten years ago. The test results continually flow into series development. The latest test runs at the physical limit are providing the Audi engineers with insights for the development of automatic avoidance functions in critical driving situations, for example.

CESA abstract : High customer acceptance through functional integration in HMI systems (Proof Technologies)

Newly defined customer expectations want full access of interaction to the world outside of their car with all kind of benefits and additional functions. Beside new technical methods to assist human machine interaction, nowadays connectivity functions not just impact future user interfaces but also new designs and layouts of drivers activity areas focus on ease of use and simplifying the task of interaction.

The addiction of everyday’s life connection to the world of internet affects driving, the safety of passengers as well as other people in yet non-automated guided vehicle systems. This requires all kind of new technical solutions and offers automotive engineers and designers new challenges giving full accessibility to the world outside of the car by integration functions into the next generation of HMI systems.

Simplifying the usage by harmonizing full access without compromising and supporting the driver in his responsible tasks is just one known goal. The main future goal is the termination of insuring the security for the car owner, solutions for the integrity data and the answer to unpermitted observations including permanent transparency of non-relevant informations.

Towards the autonomous vehicle with french OEMS

During the Mondial de l'Automobile, a conference has been organised by french automotive learning society on the topic of the connected and autonomous vehicle. It's been a success, with speakers from Renault, PSA, Valeo and Orange.

The attendees learned a lot about technical issues and the need to get updated and much more detailed digital maps.

The target is to make test drives on real roads starting from next year and to consider the legal aspects. Traffic jam assist and remote automated parking will be the first applications.

As the leader of the french piloted driving plan, Renault has released a few months ago a concept car based on the all electric Zoe and called Next Two.

Check out the video :

PSA is also working on that topic. Here is a video about autonomous driving with a Citroën C4 Picasso :

Next december, at CESA 3.0, Jean-François Sancerin from Renault and Vincent Abadie from PSA will discuss the autonomous vehicle.
Will you attend to that event ?

Test drive with Eolab : the one liter car from Renault

CESA blog already mentioned the three concept cars from the french OEMS, showing the way to very sober cars. The aim was to achieve 2 L/100 km, thanks to lightweight construction, aerodynamics and hybrid powertrain. During the Paris Motor Show, we had the opportunity to make a test drive of the Renault Eolab.

It's an impressive demo car, with a fuel comsumption of only 1 L/100 km, thanks to plug in hybrid technology.

On Mortefontaine test track, a facility located in the north of Paris, near Roissy airport, we have made one lap behind the wheel. The result is promising with 1,58 L/100 km…

Under the hood, Eolab combines a gasoline 3 cylinder engine (the 57 kW one from the new Twingo), an electric motor of 50 kW and a 6,7 kWh lithium-ion battery. One of the key elements is a 3 speed gearbox with no clutch, but acting like a double clutch transmission. This innovative powertrain allows up to 60km electric range for a maximum speed of 120 kph.

With Eolab Renault sets the goal of making such a car accessible to masses by 2020.

CESA abstract : Next Generation Smart Sensing (Elmos)

Elmos Semiconductor AG, the world's leading supplier of ultrasonic ICs for parking assistant systems and semi-automated parking aids, is developing its next generation optical sensors for advanced driver assistant systems.

Based on its unique HALIOS(R) technology currently used for HMI center stack applications, ground classification, lane departure warning, rain-light sensors, and others, Elmos will provide a new automotive IR sensor IC, which will operate independent of the target's degree of reflectivity.

The sensor provides an absolute distance information which is very accurate and fast. The sensing principle is immune against ambient light for very robust and reliable measurement results. When connected to a booster IC the technology can measure long distances enabling applications such as blind spot detection, side distance warning, autonomous parking assist, traffic jam drive control, fog detection and many other automotive applications.

The Elmos solution is unique and patented. First prototypes will become available end of 2014 !

Paris celebrating the connected car at Mondial de l'Automobile

Wow : those who don't believe to the connected car should come to Paris and make a stop to Porte de Versailles. As an example, the brand new Espace from Renault offers a 8,7″ tablet in the center console. Not as huge as the Tesla Model S, but big enough to display with a great comfort navigation and apps (Coyote road alerts, Michelin POIs, social networks, e-mail reading…) from the R-Link store.

The Espace also comes with a HUD. Many other cars have adopted the same feature, including Land Rover with a laser technology.

An example of augmented reality at Coyote. The french provider of road alerts has integrated a camera on its news device and offers data fusion, in order to enhance the driving experience. Advices coming from a community of 2,5 millions drivers are displayed in a realistic way. The camera also records and helps in case of accident, to determine the responsabilities.

On the show, we can see that the smartphone takes the control. Volkswagen extends by example MirrorLink on the new Passat, allowing this way the replication of the mobile's menus on the on-board screen. Volvo is the only one to offer both CarPlay from Apple and Android Auto on its news XC 90.

What if you could have a remote control of your car, with a special app ? Valeo shows how the mobile phone can get data from the vehicle, lock and unlock doors and even start the car. With InBlue virtual key, the owner can share the car and send a code to friends or colleagues. Bluetooth connectiviy is enough to get access to the car.

At DS, the premium brand from Citroën, this is a similar app. DS Connect allows the owner to choose who is able to drive the cars as well, and in which area. Graphics are just superb.

To be honest, the connected car is visible on almost every booth. There are so many applications that it would take too long to tell the whole story. In short, 4 G is there, OEMs are offering apps and cloud services, and the next step is for sure the autonomous and connected car.

The European automotive electronics is a global leader : did you know ?

By Jean-Luc Maté, VP strategy and innovation at Continental Automotive France

In France, for the general public, the electronic word is taboo. Associated with the electronic term appears hopelessly spectrum of industrial relocation to the South-east. If you want to get into this, so talk instead of “embedded system” or “digital pipeline” (“ICT” in fashion), but please don't say electronics, and especially not automotive electronics.

As a pioneer among pioneers of French automotive electronics, I am pleased to announce that global leadership in this vital sector to the attractiveness and competitiveness of the smallest of our cars and tomorrow in the most connected and autonomous is simply: EUROPEAN. Europe is a leader in product innovation and design for manufacturing affordable high volumes of electronic computers, smart sensors and mechatronic actuators. All manufacturers of electronic components and assembly machines, which surprisingly those of Southeast Asia, know that perfectly. They are therefore present closer to the manufacturers and suppliers of European and French to stay in the race.
Preparing architectures and processes to maintain the momentum of reducing cost and affordable miniaturization is a constant issue for more than 40 years for the tech industry. For it is no less than 20 computers, sensors and controlled bodies that we find today on average in each vehicle. Do the math: more than 2 billion electronic controllers will be produced this year. The stakes are huge, especially if we know that the expected growth of more than 7 to 10 % per year.

“Zero Defect”, “zero compensation”, a life that tolerates recycling and firm prices down. But above all flexible factories that produce in large volumes in Western Europe and in France. Did you know ?

But then these plants even when they are already the beginnings of the famous “factories of the future” that policies are desperate for re-industrialization of France? Of course, I am convinced by the return of all those (many can unfortunately) who have visited and discoveries. No other electronics industry “High Tech” on earth has achieved this level of “Best Value”: cost, quality, reliability, volume and diversity. So why there is there not more funding in France the benefits of automotive electronics to aerospace, railway, naval, industrial, medical …? They are seekers of competitiveness and failure patterns quality, but do not have the volumes to achieve them. Some think by hiring engineers learn the recipe but were quickly confronted with the reality of the volumes.

I therefore make a vow that I wish to associate particular SEE, FIEEC and ACSIEL*: communicate together with all French electronics engineers dies “High Tech” on the performance of the existing automotive electronics and those in preparation for the vehicle of the future. Give visible and known to all the industrial field and find all the tools of an intelligent and pragmatic transfer.

As shown each year on VDI German, it is the community and the network of all engineers of a nation that contributes to leadership in its industry. SIA has definitely not stopped talking about her and her jewel automotive electronics. I'll meet you at the World Congress for CESA and a networking oriented leadership.

2 L/100 km and even less : the promise of french OEMS at Mondial de l'Automobile

It looks like a regular Peugeot 208. But, this concept car is much more sophisticated and above all achieves a fuel efficiency of just 2 L/100 km. The car illustrates the French government’s “New Industrial Plan” (“2 L/100 km for all”), which is an initiative of the country’s Minister for the Economy, Industrial Renewal and Digital Affairs.

To achieve such low figures, the work has been done on three main fronts : refined aerodynamics, weight saving and hybrid powertrain. PSA has chosen innovative Hybrid Air technology in combination with a PureTech 3 cylinder gasoline engine.

PSA has applied the same recipe to the new Citroën C4 Cactus. Aerodynamics solutions are highlighted by orange patterns.

Eolab* concept from Renault is even more efficient, achieving 1 L/100 km and 22g/km CO2 emissions on the official NEDC cycle, thanks to “Z.E. Hybrid” technology. This innovative plug in hybrid powertrain integrates a 1.0-litre 3-cylinder 75 hp SCe petrol engine, a 40 kW electric motor, a 6.7 kWh battery with 66km range, and an innovative patented clutchless 3-gear transmission.

Weight saving has been huge : 400 kg on the Eolab, thanks to a multi-material body shell combining steel, aluminium and composites, as well as a remarkable magnesium roof.

On the aerodynamics side, french OEMS have applied an active front spoiler, active rear flaps and active wheels (which react to brake temperature to maximise Cd). By the way, concept cars use new narrow and tall Michelin tyres.

A common point also to all cars : side mirrors have been replaced by thin cameras.

2 L/100 km and even less : impressive, but when shall we see such sober cars on the market ? Some of the solutions should be applied in the next three to four years. Renault says that 100 innovations have been developed and will come to production cars in the future.

CESA abstract : a highly efficiency electrical recuperation system that fits with Hybrid Air technology (PSA Peugeot Citroen)

PSA Peugeot Citroen has unveiled in 2013 a new hybrid powertrain concept – Hybrid Air – described as disruptive hybrid system that makes a major step to lower emissions and fuel economy.

With this system, during city driving cycle, the vehicle operates in Air Mode, from 60 to 80 % of the time. As thermal engine operation is resultant of this on and off mode, the alternator is mainly shut off. In consequence, the lead-acid battery has strong cycling increase and can be quickly damaged. Besides, it's not suitable to power the electrical equipement during such a long time with only battery voltage (lower than 14 volt).

To fit those requirements, PSA has developed an electrical system called “Spresso”, performing two major functions : quick storage and energy management. It can handle with high efficiency, the charge and the discharge of a high-capacity electric double layer capacitor (ELDC), minimzing spare stored energy and makes it possible to supply electricity to all vehicle equipment during Air Mode.

Spresso is compatible with standard 12 volt architecture (alternator and lead-acid battery) and offers a long life and cost effective electrical system to Hybrid Air vehicles.

Georges Clooney would say for sure : “Spresso, what else ?”.
