Detection of obstacles with City
Safety
The obstructions that City Safety can detect are
vehicles, cyclists, large animals and pedestrians.
Vehicles
City Safety detects most vehicles that are either
stationary or moving in the same direction as your
car, as well as vehicles described in the "City
Safety in cross traffic" section.
In order that City Safety shall be able to detect a
vehicle in the dark, the vehicle's front and rear
lights must be working and clearly illuminated.
Cyclists
Optimal examples of what City Safety interprets as a
cyclist — with clear body outline and bicycle outline.
Optimal performance requires that the system
function that detects a cyclist must receive the
clearest possible information about the body and
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.
