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.
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.

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.
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.
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.

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 ?
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.
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.

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 !
