If the system detects a vehicle located in the blind spot or approaching quickly from the rear, a warning LED is lit in the housing of the relevant exterior mirror. If the driver activates the turn signal anyway, the LED flashes several times in rapid succession. A signal is automatically given if the driver’s intervention is required to sufficiently brake the vehicle. Maneuvering assist recognizes moving and stationary objects larger than 10 centimeters (3.9 in), such as a pillar in a parking garage or a moving vehicle.

Efficiency assist helps the driver to drive preemptively and save fuel. The system works closely together with adaptive cruise control (ACC) or adaptive cruise assist (ACA). It accesses predictive route data from navigation and Car-to-X information. In order to detect traffic signs and other vehicles, the efficiency assist uses the front camera as well as data from the front and rear-facing radar sensors. Audi pre sense front and Audi pre sense city utilize the data of radar sensors and/or the front camera, depending on the car model, to compute the probability of a collision.

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).

“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. This provides for better visibility and a more relaxed driving experience. Audi assists drivers with a broad range of assistance systems – from turn and parking assistants to the camera-based road sign recognition. They deliver more safety, convenience and efficiency, and they pave the way for piloted driving.
The driver is shown corresponding information in the instrument cluster or in the Audi virtual cockpit and the head-up display as soon as it would be sensible to take the foot off the right-hand pedal. Symbols for speed limits, bends, roundabouts, towns, or downhill slopes that indicate to the driver to slow down are displayed on the basis of the route data and recognition of traffic signs. Depending on the model the gas pedal also pulses against the sole of the driver’s foot – a clear indication to take their foot off the gas.
More Relaxed. Even in Traffic
If the car has come to a stop and other vehicles or bicyclists classified as critical are approaching from the rear, the system warns passengers not to open the doors. In a situation assessed to be hazardous, the LEDs flicker and light red. The LEDs of Audi side assist are also lit in the relevant exterior side mirror.

The cooler surroundings appear dark, while animals and people appear strikingly bright. 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. By reducing the vehicle’s speed to a safe level and then resuming the higher speed when the conditions are perfect, ACC makes navigating curves in the road just as simple. A blown fuse or a broken brake pedal switch are the two main causes of cruise control malfunctions. Problems with the ABS or the throttle control system may also be to blame. In earlier cruise control systems, a broken vacuum line may be to blame.
Maneuvering assist
A message appears on the MMI display when the system finds a suitable spot. The driver can now stop, select smartphone control in the MMI, get out and start the parking maneuver from his or her phone. This is done by pressing the Audi AI button in the myAudi app and holding it during the entire parking procedure. The driver sees a live image from the 360 degree cameras on the smartphone display. The car pulls into the parking space at a speed of up to 6 km/h (3.7 mph), maneuvering multiple times if necessary.
Together with the long-range radar and the front camera, the laser scanner forms a trio of sensors with various strengths that complement each other. It is these sensors and the central driver assistance controller (zFAS), which generates an image of the surroundings from all the sensor data, that make automated driving possible in the first place. Adaptive cruise control (ACC) offers relief to drivers especially on long trips and in stop-and-go traffic. It maintains a preset distance to the vehicle ahead by automatically accelerating and braking. The driver can choose from five distance levels and adjust acceleration and control system dynamics with Audi drive select.
You can essentially operate a vehicle hands-free in these circumstances by using adaptive cruise control. But don’t misunderstand DeMuro; you still need to pay attention to the road and shouldn’t use adaptive cruise control while doing so. Therefore, adaptive cruise control becomes a huge lifesaver in traffic situations when you would otherwise have to repeatedly speed up and then slow down. Adaptive cruise control takes care of all of that for you, saving you from having to laboriously press on the pedal for a brief while before braking once more. 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.
The adaptive cruise assist maintains proper speed and following distance via targeted acceleration and braking. The car automatically adapts its speed to the traffic situation and the route, for example at curves and cross-ways. In stop-and-go traffic as well as traffic jam situations, the ACA can bring the car to a complete stop. Depending on the duration of the stop, the car can start automatically again. In our most recent survey, we asked CR members to rate their experiences with the advanced safety and driver assistance systems on their model-year 2017 to 2022 cars.
Something as routine as a sneeze can be detrimental when traveling down the road at any speed. That is why we we offer available Advanced Driver Assistance Systems. Not for lack of your abilities, but to help fill in the gaps when anomalies occur.
The laser scanner displays other vehicles as measured cuboids, and it also measures such information as distance and orientation, which it distributes to the partner control units. With its large horizontal aperture, it detects cars entering the lane very early. Detailed information about structures on the side of the road, such as guardrails, round out the spectrum. Automatic cleaning and heating of the covering panel keep it operational even in inclement weather and spray as long as the conditions aren’t too extreme. When the preset limit is reached, the vehicle gently throttles the speed down. The speed limit is not exceeded even if the driver applies more pressure to the accelerator pedal.
In calculating a suitable evasive maneuver corridor, it takes into account the distance, width and offset of the vehicle driving ahead. Collision avoidance assist is available over a speed range from approx. 30 to 150 km/h (18.6 to 93.2 mph), and it assumes that the driver is actively steering throughout the maneuver. The driver is informed of the intervention by an indicator in the instrument cluster.
If the driver then actively avoids the obstacle, the assistant applies a slight steering torque that helps by correcting the driver’s steering input or helping to make a lane change. Models like the Audi A8 (2017) use a specific braking of individual wheels – with it the vehicle is made to follow the computed course. Is adaptive cruise control available in all new Audi models, or just in some of them? I’m really interested in this feature and I want to make sure I get it in my new car.
The laser scanner covers a field approximately 80 meters (262.5 ft) long, with an opening angle of 145 degrees. The roughly fist-sized component is mounted in the front bumper and, regardless of speed, emits moderated pulses of light on multiple vertical levels, which a mirror scatters in the shape of a fan. Having a wave length in the near-infrared range, the extremely short flashes of light are invisible and harmless to the human eye. They are reflected by objects in front of the car and return to the laser scanner in less than one microsecond, where photo diodes detect them.
