system disturbance

Some conditions can disturb or damage the operation of the system, such as:
– a complex environment (metal bridge, tunnel etc.);
– poor weather conditions (snow, hail, black ice etc.);
– poor visibility (night, fog etc.);
– poor contrast between the object (vehicle, pedestrian etc.) and the surrounding area (e.g. pedestrian dressed in white lo-
cated in a snowy area etc.);
– being dazzled (glaring sun, lights of vehicles travelling in the opposite direction etc.);
– windscreen obscured (by dirt, ice, snow, condensation etc.);
– ...
In these conditions, the system may not react or may brake inadvertently.

limitation of the system operation

– Each time the vehicle is started, the system carries out a calibration according to the vehicle surroundings and may be inac-
tive for a length of time between approximately two and five minutes;
– A vehicle travelling in the opposite direction will not trigger any alert or affect operation of the system;
– The radar and camera zones must be kept clean and free of any tampering in order to ensure the proper operation of the
system;
– The system may not respond to small vehicles such as motorbikes as effectively as to other vehicles;
– The system may not operate optimally when the road surface is slippery (rain, snow, black ice etc.);
– To ensure correct operation, the system needs to distinguish the complete outline of the pedestrian. So the system cannot
detect:
– pedestrians in the darkness or in poor lighting conditions;
– partially visible pedestrians:
– pedestrians less than approximately 80 cm tall;
– pedestrians carrying large objects;
– ...
In these conditions, the system may not react or may brake inadvertently.
