Scientists develop an 'intelligent car' able to learn from his owner’s driving and warn him in case of accident hazard

24.09.2009
The DRIVSCO system, which has had the participation of six European countries, detects “unusual behaviours” in drivers before a curve or an obstacle on the road, and generates signals of alarm
42 per cent of fatal road accidents take place at night, according to information of the European Car Council

Scientists from six European countries, including Spain, have developed a new computer system so called DRIVSCO that allows vehicles to learn from the behaviour of their drivers at the wheel, in such a way that they can detect if a driver presents an “unusual behaviour” in a curve or an obstacle on the road and generates signals of alarm which warn him on time to react.

Un like other similar projects, DRIVSCO goes far beyond a computer vision system for driving assistance. The concept investigated was how to get that a car learns from the user’s driving facing a curve or an approaching intersection, a pedestrian or another vehicle. Regardless the type of driving of the driver, sporty or conservative (as it adapts to his driving), the system obtains a driving behaviour pattern.

Thus, during night driving, if the vehicle detects a deviation in his way of driving in face of a curve, it interprets that it is due t the lack of visibility of the driver (as the driver has a limited visibility of the low beams field, whereas the car’s night vision system is much more powerful and has a longer range). Therefore, it generates signals of alarm to warn the driver of his “unusual behaviour when approaching a curve”, or the detection of a potentially dangerous object, for instance.

Accidents at night
The persons in charge of this project state that 42 per cent of fatal traffic accidents happen at night, according to the data of the European Car Council, “an extremely worrying figure if we consider that traffic drops about a 60% during night hours”. This is due, among other factors, to the reduced visibility during night driving.

The Spanish representation in this project fell on a research group of the Department of Computer Architecture and Technology of the University of Granada (Spain) led by professor Eduardo Ros Vidal. DRIVSCO also has the participation of scientists from Germany (University of Göttingen, University of Münster and the company Hella & Hueck), Denmark (University of Southern Denmark), Lithuania (University Vytautas Magnus), Belgium (Catholic University of Leuven) and Italy (University of Geneva).

The research group of the University of Granada has developed a system of artificial vision (analysis of the scenario) in an only chip. Such device receives input pictures and produces a first “interpretation of the scenario” in terms of depth (3D vision), local movement, image lines, etc, everything in an only electronic chip. This system can be assembled in different types of vehicles in future. In addition, they have used a “reconfigurable hardware”, so that the system can adapt itself to new field of application.

Promising results
During the tests, a group of drivers drove using DRIVSCO system so that the car could learn from their driving style. The car had also a differential GPS incorporated (with several centimetres of precision), detection systems of wheel turns, braking, etc, so that the research groups managed to check in great detail the style of driving in every case and the performance of the system. The first tests have offered promising results and have proved the usefulness of the new concept.

Professor Ros highlights that with this project “we do not intend to develop automatic driving systems (as it would be very difficult for insurance agencies and car companies to come to an agreement in the event of a crash), but advanced driving assistance systems”. DRIVSCO’s final goal is to avoid car accidents and contribute to keep drivers alert, focusing their attention to the maximum.

Part of the results of this project has been published in the renowned scientific journals “IEEE Trans on Image Processing”, “IEEE Trans. on Vehicular Technology” and “IEEE Transactions on Circuits for Video Technology”.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
