Monitoring field of the “Stopping field” type
•
The environment is monitored in a radius of up to 8 m (at 10% remission), starting from
the 2D LiDAR sensor. This is the area the 2D LiDAR sensor “sees”.
•
This monitored area is divided into so-called monitoring fields.
•
A distinction is made between monitoring fields of type
Warning field 1
and
Warning
field 2
(=
stopping field
).
•
The size and geometry of the monitoring fields can vary and must be parameterized on-
site.
•
Each monitoring field is linked to an evaluation case, which is assigned to a switching
output of the 2D LiDAR sensor.
•
If an object is detected within a monitoring field, the assigned switching output is
triggered.
•
The output signal is transferred to the control unit of the driver assistance system and
processed there accordingly.
NOTES
•
If an object is detected in
warning field 2
(=
stopping field
), the system does not stop
the vehicle.
•
The driver only receives an acoustic and visual signal to initiate braking of the vehicle.
