Audi drive select
Functions influencing gearbox control (Audidriveselect, e-tronmodes)
Functions such as the Audidriveselect modes, the e-tron modes
and downhill assist influence gearbox control.
In this case, the Audidriveselect modes and the e-tron modes
interact with selector positions D and S to generate defined combi-
nations.
The Audidriveselect button can be used to select between dier-
ent vehicle configurations (modes). The gearbox control unit
responds dierently to these modes.
Gearbox setups are tailored to the customer's requirements in a
country-specific way. For this reason, only typical dierences
between the various modes can be shown here.
oroad mode – for models with steel spring suspension
lift / oroad – for models with air suspension
If the lift/oroad mode is activated in models with air suspen-
sion, the internal combustion engine is started. This means that
electric drive is unavailable in this mode. When a speed of 30kph
is exceeded, the vehicle exits this mode and switches to allroad
mode. On models with steel spring suspension, electric drive is
possible in oroad mode. A maximum speed of 30 kph does not
apply to these vehicles.
In oroad mode the gearbox control unit assists driving in rough
terrain by using adapted functions. Gear selection follows a fixed
shift program without driver type recognition. As in selector
position S, the gears are held for longer, particularly 1st gear.
Selector position S is unavailable, but manual shifting is possible
in tiptronic mode (manual mode M). Automatic upshifting of the
gearbox is deactivated in tiptronic mode. The engine runs up to the
speed limiter without shifting up in order to prevent undesirable
up-and-down shifting. The deactivation of automatic upshifting
allows the engine to stop on a hill at full engine speed. Even if brief
loss of traction occurs, the gear is held to ensure that full drive
torque is available when the wheels regain full traction. The deacti-
vation of automatic upshifting allows the full braking eect of the
engine to be utilised when driving downhill. To protect the engine
against overspeeding, the gearbox shifts up before a defined
engine speed is reached.
allroad mode
The allroad mode does not have any eect on the gearbox setup.
eciency mode
Selector position E is displayed by the gear indicator. In eciency
mode the gearbox setup follows a defined shift program with no
driver type recognition. Upshifts are performed as early as possible
and downshifts are performed late in order to save fuel and reduce
C0
2
emissions.
In addition, the engine power output is reduced, allowing the
gearbox control unit to reduce the clutch pressure. This, in turn,
has a positive eect on fuel consumption and CO
2
emissions.
The eciency mode allows the driver to shift into tiptronic
modeM and back as well as to shift into selector position S and
back.
Individual gear indicator
The following applies to all Audidriveselect modes on the
AudiQ7e-tronquattro: the individual gear indicator is only avail-
able in selector position S and in tiptronic mode.
comfort mode
The comfort mode does not have any eect on the gearbox setup.
auto mode
Driver type recognition in drive positions D and S:
In selector positions D andS driver type recognition is carried out
on the basis of the driver's driving style. Criteria for driver type
recognition include the mode of actuation of the brake and accel-
erator pedals, the speed of the vehicle as well as transverse and
longitudinal acceleration of the vehicle within defined periods.
Accordingly, an economical driving style leads to early upshifts and
late downshifts. A sporty driving style is facilitated by late upshifts
and early downshifts.
The driving phases in which the driver adopts an ecient, eco-
nomical, sporty or manual driving style can be read out using the
diagnostic tester.
Selector position D:
Gearshifts are comfort-oriented and shift point selection is
adapted to the driver's driving style with the assistance of driver
type recognition.
Selector positionS
1)
:
If selector positionS is selected, the gearbox control unit is
running the sport program. In this program, the shift points are
sporty and adapted to the engine power range. Shift points are
configured with the assistance of driver type recognition. Shift
times and shift points vary according to setup, the range being
from the standard sport program to a handling course setup with
short, noticeable shift cycles.
dynamic mode
If dynamic mode is selected, the gearbox control unit activates the
sport program (selector position S). In dynamic mode, both the
tiptronicfunctions and selector position D are available. If selector
position D is activated before shutting o the engine, selector
position (D) is again activated when the engine is subsequently
started
1)
. If the driver wishes to have selector position S, he must
select this.
individual mode
In individual mode, the driver can freely select the gearbox setup
irrespective of other vehicle systems.
1)
After a change of terminal status, a combination of
Audidriveselect mode auto, e-tron mode EV and selector posi-
tionD is always used for restarting the vehicle.
