Adaptive cruise assist

How it works

Applies to: vehicles with adaptive cruise assist

Depending on the vehicle’s equipment, the adap-

tive cruise assist may perform the following func-

tions:

The adaptive cruise control assists you by con-

trolling the road speed and maintaining a set dis-

tance to the vehicle in front within certain limits

imposed by the system. When it detects a vehicle

in front, the adaptive cruise control can acceler-

ate and brake within certain system limitations.

When there is no traffic in front, the adaptive

cruise assist works just like a normal cruise con-

trol system by maintaining a constant speed.

When you draw closer to a vehicle in front, the

adaptive cruise control matches your speed to

that vehicle by automatically applying the

brakes, and then maintains a constant distance

(which you can adjust in the settings). As soon as

it detects no more vehicles in front, the adaptive

cruise control accelerates back up to the cruising

speed.

Fig. 126 Example: Driving into a bend

In some driving situations, the adaptive cruise as-

sist functions are restricted and you may need to

intervene by, for example, braking the vehicle

yourself:

– When driving into a bend ðFig. 126 and driv-

ing out of a bend, the system may react to a ve-

hicle travelling in the next lane and therefore

brake the vehicle. You can override this by ac-

celerating briefly.

– The system operates on the basis of informa-

tion gathered from various sensors and cam-

eras. Vehicles cannot be detected until they are

within range and inside the sensors’ field of vi-

sion ðpage 172, Fig. 116.

– In tight bends, a vehicle driving ahead which

has already been detected by the adaptive

cruise assist may no longer be recognised, and

Within certain system limits, the additional lane

guidance function helps you to keep the vehicle

largely in the centre of the lane. You can select

whether the adaptive cruise assist provides assis-

the system may accelerate unexpectedly as a

result.

– The system will not react to stationary vehicles

in the same lane if the system assumes that

you can easily steer to avoid the stationary vehi-

cle.

– The system cannot react to stationary obsta-

cles, such as the end of a traffic jam, particular-

ly at high speeds.

– The ability of the system to detect vehicles in

front is limited when they are too close, travel-

ling out of line, or moving into your lane.

– Vehicles that are not clearly discernible, e.g. a

motorcycle or cyclist travelling in front of you

and vehicles with high ground clearance or a

protruding load, are often identified late or are

not detected at all.

– The system does not react to pedestrians, ani-

mals or crossing or oncoming traffic.

steering wheel and be ready to steer at all times.

If you do not take over the steering, the adaptive

cruise assist will be stopped and the emergency

assist will be activated on vehicles which have

this function ðpage 216.

How it works

When the predictive control is active, the effi-

ciency assist function adapts the cruising speed

setting 1 for the adaptive cruise assist to recog-

nised speed limits and the road layout ahead. Af-

ter regulation for such events is completed, the

adaptive cruise assist accelerates back up to the

generally applicable speed limit or the recom-

mended speed for the road in question.

Depending on the equipment in your vehicle, the

system can access data from the navigation sys-

tem, from the camera behind the windscreen and

from the radar sensors.

You can override the predictive control at any

time by pressing the accelerator. In addition, the

control lever ðpage 195, Fig. 130 can be used to

change the speed limit control response.

– Always direct your full attention to the road

and surroundings, even when you are using

the predictive control. It is always the driv-

er's responsibility to assess the traffic situa-

tion and take appropriate care.

The predictive control is deactivated if you make

a significant change to the speed limit control re-

sponse. The adaptive cruise assist regulates the

speed to match the manually set value.

– The system does not give way to priority

traffic and does not stop at traffic lights –

risk of accident!

Setting predictive control

You can switch the predictive control on/off or

adjust the individual settings under Adaptive

cruise assist in the Driver assist menu

ðpage 175. The settings depend on the equip-

ment fitted in your vehicle.

– The speed at which the system drives the ve-

hicle through a corner may not correspond

to your own driving style or ambient condi-

tions. To avoid a risk of accident, apply the

brakes manually as necessary, and reduce

the speed setting in Adaptation to route

ahead.

Use speed limit – The regulation of the cruising

speed according to speed limits ahead can be

switched On or Off. The optional control setting

With tolerance can also be applied. In this case,

the actual speed can be above or below the set

speed briefly for increased efficiency. This may

result in a delay in observing the speed limit.

Note

– When using the predictive control, the ac-

tual road speed may be above or below the

maximum speed limit. It is always the driv-

er's responsibility to keep within the speed

limit.

Adaptation to route ahead – The function for

adapting to the route ahead can be switched Off

or adjusted individually from Slow to Fast. This

setting affects the handling characteristics of the

predictive control, e.g. how fast the vehicle will

drive through corners.

– The actual traffic signs on your route always

take precedence over the information on

the display. As the driver you are always re-

sponsible for adhering to the locally appli-

cable laws and regulations.

– The marking 1 is adjusted to the set speed

the adaptive cruise assist is not regulating

the speed.

Setting the distance

Applies to: vehicles with adaptive cruise assist

– When the vehicle is coasting, the actual

road speed may occasionally exceed or fall

below the set speed.

– The system’s control response depends on

the driving program set for the adaptive

cruise assist/the Audi drive select* mode se-

lected.

– After the ignition is switched on, a speed of

1)

130 km/h is set automatically when the

vehicle is first driven onto a motorway or

similar road, provided that no speed limits

are detected and you have not set a differ-

ent cruising speed.

Fig. 135 Control lever: Setting the distance

When you draw closer to a vehicle in front, the

adaptive cruise assist matches your speed to that

vehicle by applying the brakes, and then main-

tains a constant distance (which you can adjust in

the settings). If the vehicle in front accelerates,

the adaptive cruise assist will also accelerate up

to the target speed you have specified.

1)

– If a speed above 130 km/h has been set by

the driver on motorways or similar roads,

the vehicle will accelerate back up to this

set speed after regulation for a specific

event has been completed.

– The system will only regulate the speed at

motorway junctions or on slip roads if these

are part of the route set in the route guid-

ance.

– If incorrect values are supplied by the cam-

era-based traffic sign recognition* or if the

map material on the navigation system* is

out of date, this can cause failures or im-

plausibilities in the control response.

– While route guidance is active on the navi-

gation system, the control uses the naviga-

tion route as a reference. Implausibilities in

the control response can occur when route

guidance is inactive or if you leave the route.

WARNING

Stopping with the adaptive cruise assist

– Please note the safety precautions and sys-

tem limitations of the supporting systems,

sensors and cameras ðpage 171 to

ðpage 174.

The adaptive cruise assist also helps you when

driving in congested traffic. If a vehicle in front

stops, the adaptive cruise control applies the

brakes (within the system limits) and holds the

vehicle at a standstill.

cle will start moving even if there is an ob-

stacle between your car and the vehicle in

front. Always make sure that there are no

obstacles between your vehicle and the vehi-

cle in front – risk of accident!

When a message indicating that the vehicle is

ready to drive off is shown on the display and the

vehicle in front drives off, your vehicle will auto-

matically start moving ð

.

The system evaluates the driver’s grip on the

steering wheel in stop-and-go traffic. With at

least one hand on the steering wheel, the driver

is recognised to be ready and, in this way, can ex-

tend the period in which the vehicle is ready to

drive off.

Note

For safety reasons, the adaptive cruise assist

is activated only if

– the driver's seat belt is fastened,

– all the doors and the bonnet are closed,

not stored, distance  (time-based distance of

approx. 1.8 seconds) is automatically selected as

the default setting.
