Episode 2: How to keep a safe distance to the vehicle in front of you with adaptive cruise control (ACC).
What is it?
In the city or on the motorway, ACC regulates speed in line with the speed of the preceding car within the system limits up to the speed set by the driver. The system maintains the specified gap.
How does it work exactly?
A sensor in the front continuously transmits radar waves into the area in front of the car. On the basis of these signals, ACC controls interventions in the engine management and braking systems. Thus the vehicle maintains the desired safety distance. As soon as the road is clear, the vehicle accelerates to the preset speed.
How does it help me?
On long journeys and in traffic jams, ACC can make the driver’s job considerably easier. The driver no longer has to constantly accelerate and brake – ACC automatically keeps a safe distance to the vehicle driving ahead. In stop-and-go traffic, ACC in combination with DSG (depending on the vehicle model) can brake to a stop and automatically accelerate. The assistance system makes driving less stressful and safer.
What control do I have?
In spite of ACC, the driver remains fully in control. The driver can override ACC with the acclerator pedal to increase speed, while braking deactivates the ACC function altogether.
Where can I get it?
ACC is available as an option in the Polo, Golf, Passat, Sharan and Touareg.
