176 TECHNOLOGY IN DETAIL
speed is maintained automati-
cally as long as the distance to
motorists and cyclists in front
does not fall below the dis-
tance selected by the rider. If
it is undershot, the speed is
reduced until the desired dis-
tance is reached again.
The rider is still in charge and
can intervene at any time and
overrule ACC.
The ACC function has two
characteristics: Comfortable
and Dynamic. They influence
the acceleration and decelera-
tion behavior when control is
activated.
How does ACC work?
Objects in front are detected
by the front radar sensor. At
the same time, the radar sensor
uses the yaw rate and vehicle
speed to determine the driving
path, i.e. the corridor in which
the motorcycle will move in the
next approx. 100 m. If one of
the detected objects is located
in the driving path, a response
is triggered and the speed is
adjusted to ensure that the de-
sired distance to the object is
achieved.
Control functions of ACC
ACC control is divided into the
three following control func-
tions:
Cruise control: The speed
stored by the rider is
adjusted.
Distance control: The speed
stored by the rider is adjusted
while taking into account the
distance to the vehicles in
front.
Curve control: When riding
around curves, the speed is
also reduced as necessary and
the function aims to achieve a
comfortable angle (e.g. 20°).
In addition, the braking and
acceleration dynamics are lim-
ited as the angle increases
so that the rider is not sur-
prised by sudden braking or
acceleration maneuvers. For
example, curve control pre-
vents unexpected acceleration
when an object is lost and the
selected speed is too high. An
object can be lost if the vehi-
cle in front is only detected by
the radar to a limited extent
when it is traveling around the
curve.
