The driver can set the distance in five steps and adjust acceleration using the modes in Audi drive select. If the vehicle is equipped with S tronic, the system covers a speed range of 0 to 200 km/h (0 to 124.3 mph); with the manual transmission, the range begins at 30 km/h (18.6 mph). In normal traffic, the Stop&Go function works together with the S tronic to bring the Audi A1 Sportback to a complete stop behind the vehicle ahead. If the driver pushes the brake after the vehicle comes to a complete stop, the system remains active. Adaptive cruise control (ACC) is like traditional cruise control, but smarter.

Adaptive cruise assist uses radar, camera, laser scanner, and ultrasonic sensors to continuously monitor the environment and help assist with highway driving. The highly intelligent ACC system utilises data from other driver information systems to continuously analyse the vehicle’s surroundings. It’s able to recognise intricate scenarios and predictively support the driver with reflection and composure. A safety measure is included, alerting the driver when a collision is imminent, tightening seat belts and priming air bags in preparation. As an additional benefit, fuel economy can be improved with ACC usage, thanks to smoother throttle operation and greater consistency than manual driving. Working within a speed range of 0 – 155mph, the system emits a narrow radio frequency beam from radar sensors installed at the front of the Audi to seek out vehicles ahead.

Radar sensor: the ACC in the Audi A4
The ACC stop & go uses two radar sensors installed at the front of the vehicle which are automatically heated when it is cold. They transmit radar waves at a frequency of 76.5 gigahertz covering a roughly 40 degree wedge-shaped field measuring approx. The driver can influence the function of the ACC stop & go; the interval to the vehicle ahead and the control system dynamics are adjustable in steps. The system accelerates smoothly or sharply, depending on the setting.
Using the multifunction steering wheel, select Driver assistance view to see the adaptive cruise control display in the instrument cluster. When the ignition is turned off, the most recent distance that was set will be saved. The standard lane departure warning helps the driver to keep the car in the lane. At speeds of 65 km/h (40.4 mph) and above, the system uses a camera to detect the lane markings and uses corrective steering interventions and warning vibrations to keep the car in the lane.
The adaptive cruise control with Stop&Go function
In times of heavy traffic, though, you essentially don’t have to do much if adaptive cruise control is activated. Additionally, adaptive cruise control ensures that you won’t be exhausted at the conclusion of your drive if you experience heavy traffic as frequently as DeMuro does. Press the cruise control ON/OFF button on the steering wheel to activate the feature. If your car has a Head-Up Display, or a cluster display, you’ll see a white ADAPTIVE CRUISE CONTROL icon when the system is turned on. An arc with a tiny triangle pointing through it or a speedometer with a car on top might be the icon. When driving at any speed, something as commonplace as a sneeze might be dangerous.

Audi advanced Driver Assistance systems
Respondents answered questions about their satisfaction with the systems. The systems use lasers, radar, cameras, or a combination of those. If traffic slows to a stop, most ACC systems will bring the car to a complete stop, then bring it back up to speed when traffic gets going again. Others work only within certain speeds and/or might not start to accelerate automatically. Additionally, because you don’t have to make many turns in these instances of heavy traffic, you won’t need to utilize your steering wheel as much. You can essentially operate a vehicle hands-free in these circumstances by using adaptive cruise control.

Audi pre sense front and Audi pre sense basic
It works closely together with other driver information systems, and each of them contributes its own specific strengths. All told, the ACC stop & go in the Audi A8 takes data from around 30 control units, with which it works to continuously analyze the complete area around the vehicle. This expanse of knowledge enables the system to recognize complex scenarios and predictively support the driver. Because it also cooperates with the navigation system, it knows the course of the selected route in advance and can also compute the lane in curves, for example. The ACC stop & go uses its networked knowledge in numerous situations.
Audi offers the adaptive cruise control in a number of different versions, with and without stop & go function, depending on the model series. The function of the individual versions varies slightly due to the different degrees of networking and the expansion levels. It keeps the Audi A1 Sportback at the desired distance from the vehicle ahead.
If no vehicles are within range, the pre-set speed will be maintained, but if a vehicle is detected ahead, that’s when the active aspect of the system comes into its own. The A1 Sportback sets the standard in its segment with this system. The radar sensor recognizes critical situations involving other vehicles, crossing pedestrians or cyclists ahead of the vehicle, even when visibility is poor such as in fog.
ACC systems allow you to set a desired speed until your vehicle encounters slower-moving traffic. Once the traffic starts moving again or if there is no longer a car in the lane ahead, ACC will accelerate to resume the previous set speed. Although ACC systems may take some getting used to, our survey respondents told us they appreciated the stress relief the feature brings.
As errors may occur or availability may change, please see dealer for complete details and current model specifications. Active lane assist can provide steering guidance to help the driver keep the vehicle in the lane. Detecting lane markings, roadside structures and vehicles in adjacent lanes allows the system to make a virtual driving path to help guide the vehicle. The ACC is connected to the Audi navigation system and is capable of reading traffic signs and providing the driver with that information. For example, when the speed limit changes from 55 to 35, ACC automatically reduces the vehicle’s speed to match the new restriction.
