Adaptive Headlights - BMW R 18 B 2021 Rider's Manual

Influence of gradient on brake pressure
and starting behavior
Stopping on a slight incline builds up only
a small amount of brake pressure. The
brake is released quickly when riding
off, making it possible to ride off more
smoothly. Additional opening up of the
throttle grip is hardly even necessary.
Stopping on a steeper slope increases the
amount of brake pressure built up. The
brake is a bit slower to release when rid-
ing off. More torque is required to ride off,
making additional opening of the throttle
grip necessary.
Behavior when the vehicle is rolling back
or skidding
The brake pressure increases when the ve-
hicle is rolling back with Hill Start Control
active.
If the rear wheel skids, the brake is re-
leased again after approx. 1.1 yards (1 m).
This prevents, for example, the vehicle
from skidding with a locked rear wheel.
Releasing the brake when switching off
the engine or during timeout
Hill Start Control is deactivated when the
engine is switched off using the emergency-
off switch, when the side stand is folded out,
or after it times out (10 minutes).
In addition to the indicator and warning
lights, the following behavior is to alert the
rider to the deactivation of the Hill Start
Control:
Brake warning jerk
The brake is released briefly and is imme-
diately reactivated.
This causes a jerking behavior that the
rider can feel.
The fully integral ABS brake system sets a
speed of approx. 0.6-1.2 mph (1-2 km/h).
The rider must brake the vehicle manually.
After two minutes, or when the brake is
actuated, the cruise control is deactivated
completely.
When the ignition is switched off, the
holding pressure is built up immedi-
ately and without brake warning jerk.

ADAPTIVE HEADLIGHTS

with Adaptive Lights
How do the adaptive headlights work?
The standard installed dimming unit in the
headlight consists of two reflectors that gen-
erate low beams using LED. Ride height sen-
sors at the front and rear wheel suspension
provide data for ongoing headlight distance
control. Thanks to the pitching compensa-
tion, the light always illuminates the optimal,
preset area when riding on straight stretches
of road, regardless of the riding conditions
and load status. Using Adaptive Headlights,
the dimming unit additionally rotates around
an axis, depending on the angle, and com-
pensates for the angle of roll of the vehicle.
The angle of rotation is 70° (±35°).
In addition to the pitching compensation, the
low-beam headlight learns to compensate
for the angle at which riding takes place.
Both movements are overlaid so that a high-
light in the curve results. This results in sig-
nificantly improved illumination of the road
when riding around curves and thus an enor-
mous increase in active riding safety.
