Function B
System characteristics of the turn assist function
• Turn assist is available only at speeds below 6.2 mph
(10 km/h).
• The indicators must be activated.
• In the case of left-hand-drive vehicles, the system only
works when turning right.
• This is indicated audibly and visually.
Deactivating turn assist
If Audi pre sense is switched off in the MMI, turning assist
is not available. The system can be reactivated in the MMI.
If the system has been shut off via the MMI, it will auto-
matically be switched on the next time the ignition is
switched on.

Audi pre sense
The driver of vehicle (E) wants to turn right and indicates by
actuating the left indicator. Vehicle (E) is travelling slower
than 6.2 mph (10 km/h). Audi pre sense front continuously
monitors the traffic ahead of the vehicle with the aid of ACC
and the front camera. As a result, Audi pre sense front
knows that another vehicle (A) is approaching in the
oncoming direction.
Audi pre sense front also knows that the driver is planning
to turn left (from the actuation of the indicator).
In this case, Audi pre sense front would automatically
initiate emergency braking via J104 with the result that
vehicle (E) is brought to a halt in its own lane. The driver is
alerted visually and audibly to the fact that the vehicle is
braking automatically
1)
. If the vehicle has automatically
brought the vehicle to a halt without driver input, further
audible signals will sound. These signals alert the driver to
the fact that he must actively take control of the vehicle
(for example, by braking).
If Audi pre sense detects that a critical situation would
occur due to the current turning maneuver, hydraulic brake
assist is reconfigured by ABS Control Module J104. In
addition, the deployment algorithms for hydraulic brake
assist are adjusted. This action ensures the rapid response
of the brake during a braking maneuver. If the driver of
vehicle (E) were now to continue the turning maneuver and
move off, Audi pre sense front would detect this based on
the information provided by the speed sensors of ABS
Control Module J104.
