Coordinated avoidance maneuvers

04.11.2008
A road construction barrier falls over: The car driver can’t avoid it, since there are cars on the lane next to him. In future, a new software program will enable cars to coordinate maneuvers together in dangerous situations.

A child runs across the street without paying attention to the traffic, just as a car approaches at speed. It’s too late to slam on the brakes, and the driver can’t swerve either, as there is another car on the neighboring lane.

An accident seems inevitable. A new software program, that for the first time can help several cars to coordinate their movements together, could take the edge off such a situation in future. The vehicles form a network via car-to-car communication and communicate automatically.

“In dangerous situations, the cars can independently perform coordinated maneuvers without their drivers having to intervene. In this way, they can quickly and safely avoid one another,” explains Thomas Batz, who developed the software together with his colleagues at the Fraunhofer Institute for Information and Data Processing IITB in Karlsruhe and at Karlsruhe University ‘s chair for interactive real-time systems.

For this system, the researchers are making use of cognitive automobiles that are autonomously driven for short periods of time. The vehicles are equipped with car-to-car communication and integrated sensors such as cameras, GPS and radar systems so that they can autonomously recognize their surroundings and avoid any potential obstacles. The vehicles form cooperative groups that can act in unison. These groups are made up of cars that are traveling in the same direction and are in radio range of one another.

Since their speeds and destinations vary, they are constantly re-grouped. Every vehicle in a group automatically transmits its current position and driving situation to a car that has been designated as the group coordinator. This car gathers the information from all the other cars in its group and draws up a common relevant picture of the group's situation.

Sudden dangers, such as a child running onto the road, are recognized not only by the car directly affected but also by the group coordinator. If the car in question can neither brake nor swerve because there is another car on the lane to the right, the group coordinator steps in: It orders both vehicles to swerve to the right in a coordinated maneuver in order to avoid an accident with the child and a collision with one another.

Unlike in current driver assistance systems such as the anti-lock braking system (ABS), control of the car is taken over automatically. The system is currently under development: Its group formation function has already been implemented, and the researchers are now improving its ability to recognize and assess dangerous situations and to choose appropriate driving maneuvers.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
