TRW revisite la ceinture de sécurité
Aux côtés des nouveautés des constructeurs automobiles, les visiteurs du salon de Genève découvriront une nouvelle génération de ceinture de sécurité. Ainsi, à la place de la languette et de la boucle de ceinture, le procédé utilise un "attrape sangle", qui permet un bouclage et débouclage semi-automatique. Ce système est exposé sur la navette concept-car microMAX, conçue pour effectuer de courts trajets en milieu urbain, avec des places debout non conventionnelles.
Selon Swen Schaub, Senior Manager, Engineering Strategy and Communication de TRW, "le concept est basé sur des fonctionnalités de ceintures de sécurité éprouvées. Le bouclage semi-automatique pratique et facile pour entrer et sortir du véhicule pourrait être appliqué sur des concepts de véhicules conventionnels, augmentant ainsi le taux d’utilisation de la ceinture de sécurité pour des courtes distances".

Scientists Create Sideview Mirror Without Distortion
Three scientists working in South Korea and the US have developed a new lens for side view mirrors that provide a wider view and less distortion than current mirrors. Multi-focal eyeglasses inspired the design. The scientists believe that it eliminates blind spots while driving. Unlike current mirrors it eliminates the problem of objects in the mirror being farther away than they appear.
For decades, North American cars have used two types of side view mirrors. The mirror closer to the driver is flat and gives an undistorted view of the side of the car. The passenger mirror is convex, which widens the field of view but distorts images. Objects look smaller and farther away than they actually are.
European cars have tried to solve this by using mirrors with two separate areas. The inner area has less distortion than the outer area but provides a wider field of view.
Hocheol Lee and Dohyun Kim from Hanbat National University in South Korea and Sung Yi from Portland State University in Oregon took inspiration from multi-focal eyeglasses.
"Like multifocal glasses that give the wearer a range of focusing abilities from near to far and everything in between, our progressive mirror consists of three resolution zones: one for distance vision, one for close-up viewing and a middle zone making the transition between the two," said Lee.
With their design, the images on the inside and outside are undistorted, but the section in the middle would still distort the image somewhat. However, the design provides a viewing angle more than twice as wide as a conventional mirror.
The design would not be much more expensive than current mirrors. It can be made using conventional glass molding techniques.
Because of safety implications, automotive mirror designs are regulated in the United States. For the mirrors to be used in cars, it would need approved.
The other problem with this research is that it is rapidly becoming outdated. Higher trim levels of the Honda Accord already shows the view from the rearview camera on the center display when changing lanes, and the Volkswagen XL1 is slated to use a similar system. We are rapidly entering a world where cars may not have side view mirrors.

Ants would help us to reduce traffic jams???
Many insects travel using simple, logical rules that determine where they go and why, but these rules are often implemented to create very complicated behaviors. A traffic researcher at Carnegie Mellon University has applied this knowledge to human traffic and has created a smart traffic light.
Ozan Tonguz's solution hinges on vehicle-to-vehicle communication that sends road data among the cars on the road. This technology is already in real world tests in Ann Arbor, Michigan.
With Tonguz's system, the traffic light would receive data from oncoming traffic. It would decide, which direction had the largest amount of traffic, and change the light to green in that direction. When the traffic decreased so that the other direction had more oncoming cars, the light would change to let those cars go.
Tonguz claims that in computer simulations, the system allows 40% to 60% to move through an intersection than a current traffic light. His plan also already received $2 million in research funding to test in the real world.
In the real word, Tonguz's traffic light might need some adjustments. If the intersecting streets did not have roughly equal amounts of cross-traffic, some drivers could be waiting longer than current systems until enough drivers are available to offset the more popular route.
It is also going to be a decade or more before new cars are equipped with vehicle-to-vehicle communication.
