Pedestrians
Examples of what the system considers to be a
pedestrian: clear body contours.
For good performance, the system's function
for pedestrian detection needs the clearest
possible information about the contours of the
pedestrian's head, arm, shoulders, legs, torso
and lower body in combination with normal
human movements.
In order to detect a pedestrian, there must be
a contrast to the background, which could
depend on clothing, weather conditions, etc. If
there is little contrast, the person may be
detected late or not at all, which may result in
a delayed reaction from the system or no reac-
tion at all.
City Safety can detect pedestrians even in
dark conditions if they are illuminated by the
vehicle's headlights.

WARNING
City Safety is supplementary driver sup-
port, but it cannot detect all pedestrians in
all situations and, for example, cannot see:
partially obscured pedestrians, people
•
in clothing that hides their body con-
tour or pedestrians shorter than 80 cm
(32 in.).
pedestrians if the background contrast
•
of the pedestrians is poor - warning
and brake interventions may then be
late or not occur at all.
pedestrians who are carrying large
•
objects.
The driver is always responsible for ensur-
ing that the vehicle is driven correctly and
with a safety distance suitable for the
speed.
Large animals
Examples of what City Safety would interpret as a
large animal: stationary or moving slowly and with
clear body contours.
For good performance, the system's function
for detecting large animals (e.g. moose,
horses, etc.) needs the clearest possible infor-
mation about body contours. This entails
being able to detect the animal straight from
the side in combination with normal move-
ments for that animal.
If parts of the animal's body are not visible to
the function's camera, the system will not be
able to detect the animal.
City Safety can detect large animals even in
dark conditions if they are illuminated by the
vehicle's headlights.
