  • First Audi models network with traffic lights for free-flowing city driving




    • Traffic Light Information is the first true Vehicle-to-Infrastructure(V2I) service by an automobile brand
    • The service starts up with variations on the Audi A4 and Q7 in Las Vegas
    • Networking is essential for autonomous driving in cities

    If you know in advance when a traffic light will switch from red to green, your driving is more relaxed and efficient. Audi is the first car manufacturer to connect the car to the city infrastructure – an important step towards autonomous driving. In Las Vegas Audi A4 and Q7 models are now able to display traffic-light phases directly in the car. Further U.S. cities will follow, and introduction of the system is planned in Europe. Traffic Light Information optimises trafficflow, saves valuable time and reduces environmental impact.

    Audi of America is cooperating with several cities in North America to upgrade the infrastructure for Vehicle-to-Infrastructure (V2I) technology. “For the first time, our cars are exchanging data with traffic infrastructure in real time. Drivers can adapt their behaviour to the situation and move through city traffic in a much more relaxed and controlled way,” says Andreas Reich, head of Electronics Pre-Development at AUDI AG. “We increase energy efficiency when we connect our Audi models to smart cities.Further V2I services will follow, making the car into an interactive mobile device. We see autonomous driving as the end of this development.”


    As a first step, all Audi A4 and Q7 models produced for the U.S. market since June 2016 and equipped with Audi connect have this function on board. In the USA, municipal traffic management centres will communicate the traffic-light data to Audi’s project partner Traffic Technology Service sTTS. Here the data are prepared and sent to the on-board computer in the Audi via a fast Internet connection, for example 4G/LTE, in real time.


    Fuel savings of up to 15 per cent


    The first function of the Traffic Light Information V2I component is called Time-to-Green. In the Audi virtual cockpit or head-up display, drivers see whether they will reach the next light on green while travelling within the permitted speed limit. If not, a countdownis provided of the time remaining until the next green phase– and driverscan throttle back in good time. Pilot projects in Europe have shown that drivers exercise more foresight thanks to this information about traffic lights.This has a beneficial overall effect on traffic flow. “In our tests the number of cars that had to brake to a stand still in traffic fell by around 20 percent. This saved time for the driver and also made fuel savings of about 15 percent in the pilot project,” says Michael Zweck, project manager for Audi Traffic Light Information.


    First of all, Audi customers will use this service. The development work that Audi is investing in traffic-light systems will also benefit customers of other brands in future. The increasing spread of the technology will help city traffic planners to understand the causes of hold-ups and optimise the phasing of traffic lights.


    In future Traffic Light Information could be linked up to smart navigation and used for new powering concepts. For example,“green waves” in traffic-light sequences could be incorporated in route planning. It is also conceivable that Audi e-tron models could make greater use of braking energy by charging the battery as they decelerate at a red light.


    Audi also intends to introduce the technology in Europe. In Berlin, Ingolstadt, Garmisch-Partenkirchen and Veronathere have already been extensive pilot projects. In Berlin alone, some 700 traffic lightsin the inner city have been connected to the service. Across Europe, however, unified data standards and digital infrastructure do not exist: “In Europe highly diverse traffic technology is in use, as the infrastructure has developed locally. We are working on harmonisation of the data that have been prepared. After that has been done, we can provide


    Traffic Light Informationin Europe too,” Michael Zweck announced.

    The inlet manifold will not get cleaned as the terraclean is a fuel based cleaner. They swap the fuel lines for there machine and run it on a mixture

    Re: Rough idling

    See if you can find someone with VCDS or a garage interested in doing some diagnostics and check the injector and torsion values as mentioned by Crasher.

    Re: alleged diesel injection pump issue . a6 2.5 ti AKE , starts on the button though

    Check the insulation on the wires from the ECU on the injection pump, they can short and fry the ECU.

    It is going into limp mode so first of all get it fault code read. If this shows the engine is suffering over boost then the turbo will have to be removed

    It can be a sketch to get the ABS ECU to complete the test, drives me to distraction sometimes. One I did a few weeks back just would not pass on VCDS

    Re: A6 Avant HVAC Blows Cold Air when Engine on low revs or Idle

    Do the audis have duo valves like the mercs for water heating control?

    As others have said a proper vcds or alt scan will cut out a lot
