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.

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.

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.

When the navigation system detects that you are going to make a turn, ACC automatically reduces the speed to a safe level before resuming it once the turn has been made. The new Audi A1 Sportback offers various systems to make parking easier. For the first time there is a reversing camera in addition to the parking system, rear.

Deceleration is limited to roughly 4 m/s2 (13.12 ft/s²), which is a good third of what is possible. In stop-and-go traffic, the ACC stop & go automatically slows the car to a stop. After a brief stop, the vehicle moves off again automatically and follows the vehicle ahead. After a longer stop, the driver must tap the accelerator or the cruise-control lever. The adaptive cruise control with stop & go function is a highly intelligent system – thanks to its broad networking.

Standard: Lane departure warning and speed limiter

The parking system plus also detects objects in front of the car and informs the driver acoustically and visually. Not all systems work at low speeds, so drivers who plan to use ACC in slow traffic should check the limitations of any system they plan to buy. These particular systems will often have the words “traffic jam” or “stop and go” in their name. “I use the feature mostly on the freeway and in stop-and-go traffic. I find it reduces tension and fatigue,” wrote a 2020 Subaru Outback owner. “It is so nice to just set it and let the car worry about the traffic,” they told CR.

On our radar, off your nerves

The front seat belts are electrically tensioned, the windows are closed and the hazard warning lights are switched on. Our suite of available systems is designed to detect and help reduce the likelihood or severity of the worst-case scenario. With a myriad of sensors and cameras working in tandem, our available driver assistance systems offer a broad range of confidence-inspiring technology, helping your peace of mind as you travel down the road. When driving in slow-moving traffic, the ACC stop & go automatically slows the car to a stop when necessary. The vehicle moves off again automatically if it has only briefly stopped, following the vehicle ahead. The accelerator or cruise control lever must be tapped if the car has stopped for a longer period, much the same as the Audi start-stop system.

We provide available advanced driver assistance systems as a result. Not out of a lack of skill, but to help fill in the blanks when oddities happen. Every ACC system works slightly differently, says Kelly Funkhouser, manager for vehicle technology at CR. Audi pre sense rear uses radar sensors in the rear bumper to help detect an impending rear-end collision, and can initiate preventive measures. Among other things, this system helps by pretensioning the front safety belts and automatically adjusting the occupants' seats to a more optimal position.

The driver assistance systems in the new Audi A1 Sportback come directly from the full-size class. They keep the car at the right distance from the car ahead, make it easier for drivers to maintain their lane, and they help with parking. If traffic slows down, you slow down – and if traffic speeds up, you speed up, so you can enjoy the drive without having to disengage and resume Cruise Control as traffic demands. Perfect for long journeys and motorway driving, it’s a feature that you never knew you wanted – but as soon as you have it, you can’t live without it. Autoblog’s authors expressed their admiration for this function, noting that many navigation systems alert drivers to approaching turns or exits when it’s almost too late to take a decision.

While driving at slow speeds, two ultrasonic sensors detect suitable parallel or perpendicular parking spots. The driver just has to engage the proper gear, use the accelerator and the brakes. With the new version of the park assist, the A1 Sportback can also pull forwards into perpendicular parking spaces, maneuvering multiple times if necessary. Stop-and-go adaptive cruise control makes it easier to accelerate, decelerate, and maintain distance and speed. Radar, camera, laser scanner, and ultrasonic sensors are used by adaptive cruise assist to continuously monitor the environment and support highway driving.

What models of Audi have adaptive cruise control?

Pushing the operational lever away from you to position “0 until it engages will turn off adaptive cruise assist. Except for those who choose the premium trim level, there is no simple cruise control. While you’re stopped, you can set the Adaptive Cruise Control speed on select vehicles (the system must be on, you must apply the brake pedal and your vehicle must be in FORWARD gear). While moving at the specified speed, press the SET button to select a cruise speed. When the system is in use, the white ADAPTIVE CRUISE CONTROL symbol will turn green. Using forward-facing camera and radar systems, this available feature can help detect potential threats and aid by initiating preventative measures, helping to protect you from the world around.

The figures do not refer to a single, specific vehicle and are not part of the offering but are instead provided solely to allow comparisons of the different vehicle types. These features are usually activated using a button on the steering wheel with the image of a car next to a speedometer with an arrow pointing at it. A conventional cruise control system does not automatically keep a set distance away from the car in front, and it is indicated by a similar logo without the car next to the speedometer.

Also standard is the speed limiter, which reliably prevents the A1 Sportback from exceeding a selected maximum speed. “Most ACC systems can only be set to speeds above 20 mph but will slow the vehicle to speeds below that in stop-and-go traffic,” she says. “There are a few systems out there that don’t bring the car all the way to a stop but instead just shut off at low speeds. That can be dangerous when you’re traveling behind another slowing vehicle.” She recommends reading the automaker’s website closely and learning about the speed ranges before using ACC while on your test drive.

DeMuro claims that the benefits of having adaptive cruise control in his vehicles have altered his quality of life. A straightforward but sophisticated technology is adaptive cruise control. It does this by using the radars in your car to detect the vehicle in front of you, and depending on what it does, it will either accelerate or decelerate your vehicle up to a maximum speed that you can specify.
