bicycle outline, requiring the ability to identify the
bicycle, head, arms, shoulders, legs, upper and
lower body plus a normal human pattern of move-
ment.
If large parts of the cyclist's body or bicycle are
not visible to the function's camera then the sys-
tem cannot detect a cyclist.
For the function to be able to detect a cyclist,
he/she must be an adult and riding a bicycle
designed for adults.
WARNING
City Safety is supplementary driver support,
but it cannot detect all cyclists in all situations
and, for example, cannot see:
partially obscured cyclists.
•
cyclists if the background contrast of the
•
cyclist is poor – warning and brake inter-
ventions may then be late or not occur at
all.
cyclists wearing clothing that obscures
•
the body outline.
bicycles loaded with large objects.
•
The driver is always responsible that the vehi-
cle is driven correctly and with a safety dis-
tance adapted to the speed.
Pedestrians
Optimal examples of what the system regards as pedes-
trians with clear body outlines.
For optimal performance, the system function
that detects pedestrians must receive the clear-
est possible information about the body outline,
requiring the ability to identify the head, arms,
shoulders, legs, upper and lower body plus a nor-
mal human pattern of movement.
In order that it shall be possible to detect a
pedestrian there must be a contrast with the
background and this will be affected by such
things as clothes, the background and the
weather. With poor contrast the pedestrian may
either be detected late or not at all, which may
mean that warnings and braking are late or omit-
ted.
DRIVER SUPPORT
City Safety can also detect pedestrians in the
dark if they are illuminated by the car's head-
lamps.
WARNING
City Safety is supplementary driver support,
but it cannot detect all pedestrians in all sit-
uations and, for example, cannot see:
partially obscured pedestrians, people in
•
clothing that hides their body contour 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 larger
•
objects.
The driver is always responsible that the vehi-
cle is driven correctly and with a safety dis-
tance adapted to the speed.
