Here's how it works: "ACC" uses a radar sensor (for the cruise control), a camera in the windscreen and the route data of the navigation system. The Arteon can "see" speed limits using the camera and the associated traffic sign recognition. These are adopted by the "ACC". The route data can even be predictively forwarded to the navigation system. This "speed assistant" represents a clear comfort gain especially on long-distance motorways with constantly changing speed information. A "bend assistant" is active at the same time: Using the route data of the navigation system, the car can recognise its position within system limits and adjust the speed on approaching bends, roundabouts and intersections. Local entry and exit signs can also be detected. The "Front Assist" surroundings monitoring system including "City Emergency Braking System" is always integrated in the "ACC". In combination with the automatically shifting DSG, the Arteon can also automatically start up again with "ACC" – for example, in stop & go traffic.
The "adaptive cruise control" is active in a range from 0 to 210 km/h (with DSG); starting at 30 km/h ACC is able to keep the desired speed constantly. Thanks to the predictive speed control system, the system can increase comfort as outlined; at the same time, though, the new "ACC" generation can also contribute to the reduction of fuel consumption thanks to the predictive braking and acceleration functions.
In essence: The "adaptive cruise control ACC with predictive speed control" helps the driver within system limits, but it is the driver who retains overall control at all times for the car and the current situation. The semi-automatic system can be "overridden" at any time by switching it off, braking or accelerating.
