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.
Radar sensor: the ACC in the Audi A4
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.

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.

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.
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.

Driver Assistance
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.

What models of Audi have adaptive cruise control?
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.

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.

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.
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.
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.
