The EDL function has been adapted in the
following areas specifically for use in the Audi
allroad quattro and its off-road use.
• Significant reduction of the minimum
control thresholds and corresponding
adaptation to engine / gearbox versions.
• Re-adapted synchronous brake
intervention, e.g. simultaneous pressure
increase at all 4 wheels to support the TCS
function.
• Modification of the centre differential lock.
• Optimisation of diagonal brake
intervention.
• Extension of the speed limit value for EDL
control at 100 km/h.
Off-road EDL
The EDL in the allroad quattro has also been
adapted to accommodate the low range
additional shift stage.
As the wheel torque is increased by a factor of
1.54 in low range mode, it is desirable to reset
the minimum control thresholds.
As shown in illustration 241_099, the
minimum control thresholds can be very
low in low range mode.
When cornering, this would lead to
undesirable EDL control intervention.
EDL control is therefore suppressed when
cornering is detected (via the ESP input
values).
The function is automatic when
the additional shift stage has been actuated.
