Audi A4: Predictive control
Applies to: vehicles with Audi adaptive cruise control and efficiency
assist
With predictive control, efficiency assist adapts
the set speed in adaptive cruise control (1), fig. 108 based on detected speed
limits and the upcoming route. Once the system
no longer detects any incidents ahead, adaptive
cruise control will accelerate back up to the last
speed that the driver set. After switching on the
ignition, the availability of predictive control is
indicated by a message when the adaptive cruise
control is first activated.
Incident symbols indicate the situation to which
predictive control is reacting, Situation
symbols.
Requirements
- Predictive control is switched on in the MMI
- Adaptive cruise control is actively regulating
- The system can only react to speed limits that
are 15 mph (20 km/h)1) or higher.
1) Analog instrument cluster: 20 mph (30 km/h)
Overriding control
The driver can override the predictive control
based on the route ahead at any time by pressing
the accelerator pedal. If the system changes the
vehicle speed to adapt to speed limits, you can
change the speed using the lever,
fig. 111.
Messages
If and a message with Predictive
control is
displayed when there is a malfunction, the efficiency
assist functions are unavailable or limited.
A message that indicates the cause and possible
solution may appear with some displays. The
weather conditions may be too poor or a sensor
may be covered. Clean the area in front of the
sensors and try to turn on the systems
again later.
If the malfunction remains, drive to an authorized
Audi dealer or authorized Audi Service Facility
immediately to have the malfunction corrected.
WARNING
- Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras.
- Pay attention to traffic and the area around
your vehicle when predictive control is
switched on. The driver is always responsible
for assessing the traffic situation.
- The system does not consider "right of way"
rules and does not respond to traffic lights,
so lack of driver attention in these situations
can increase the risk of an accident.
- The speed when driving through curves may
be different from what you as a driver would
do or may not be suitable for the weather
and road conditions. If necessary, apply the
brakes and reduce the selected speed to be
maintained in the Adjustment to curves
along route setting to reduce the risk of an
accident.
Tips
- Predictive control can exceed or drop below
the maximum permitted speed. The driver
is responsible for adhering to the permitted
speed limit.
- The traffic signs on the road always take priority
over the display. The driver is always
responsible for adhering to the regulations
applicable in the country where the vehicle
is being operated.
- If a speed limit is detected, the marking (1) of the set speed limit
will be adjusted
even if Audi adaptive cruise control is
not actively regulating.
- Control by the system depends on which
adaptive cruise control driving program is
set or on the selected Audi drive select*
mode.
- After switching on the ignition and first
driving onto a freeway or similar road without
a speed limit, the system will regulate
the speed to 80 mph (130 km/h)1). Then
the system adjusts to the last speed set by
the driver.
- There is no adaptation to speed limits when
driving through highway interchanges and
when driving on or off the expressway.
- The system can fail to provide control or the
control may be faulty if the values from the
camera-based traffic sign recognition* are
incorrect or the navigation system map data
is outdated.
- When route guidance is switched on, the
system adapts to the route provided by the
navigation system. Driving without route
guidance or leaving a route can result in
faulty control.
