A number of Audi's future technology plans happen to be revealed in new technical patents. Its not all patents cause it to be into series-production cars, but two engineering ideas — one very simple and one very complex — look set to enter production inside the next couple of years. The simple idea suggests using hinged flaps involving the spokes in an alloy wheel. The flaps move radially during the spokes like the wheel speeds up, creating a totally flat wheel cover.
According to Audi Plans application, fully enclosed wheels not just smooth airflow at speed but additionally help to enhance the car’s overall aerodynamic performance, because of alterations in air pressure beneath the car. Like the car slows, the wheel flaps open again, however the flaps will also be temperature sensitive, to allow them to speak freely when the braking surfaces become too hot. The next patent appears showing a new-generation Audi all-wheel drive system which uses an electrically driven rear axle. This can be a logical progression to the traditional quattro system, combining rapid-reacting all-wheel drive and electric drive.
However, the description says Audi is seeking a patent for any software system that uses the wheel sensors to detect the point of which perhaps one of the wheels might break traction on the slippery surface. This could be important on hybrids, because by using the regenerative braking (in which the electric motor acts like a brake while also generating electricity ) can cause wheels to slow straight away and lose grip. Audi’s innovation appears to permit brake regeneration forces — which are often fixed inside an electric car — to vary based on the road conditions. By detecting the small differences in rotational speed between the front and rear axles, the internal system also can find the friction coefficient of the road surface in real time. Even though this new quattro proposal is primarily designed to incorporate a hybrid transmission into your 4x4 drivetrain, it may also lead to the foremost intelligent and quickest-reacting all-wheel drive system yet.
