15.5.2 "Zone-based" module
The "Zone-based" module has the following settings:
Setting Data type Index Description
Zone-based collision
warning -> object ID in
zone [0..2]
Numerical
Index from zone number
(vector with 3 values,
address range from 0-2)
The ID of the next object in the zone is provided.
If the zone is free from objects, then the value is "0".
Zone-based collision
warning -> Status of
zone [0..2]
Numerical
Index from zone number
(vector with 3 values,
address range from 0-2)
The zone status is provided:
● "-1": zone not defined or zone-based warning not active
● "0": no object in the zone
● "1": at least one object in the zone
15.5.3 "Time-based" module
The "Time-based" module has the following settings:
The "Time-based" module only outputs values if the "Collision avoidance" mode (→ „13.2 Collision
avoidance“) is set to:
● [Intelligent]
● [Intelligent with side collision]
Setting Data type Index Description
ID of predicted collision
object
Numerical Single value (no index)
The object ID of the object on collision course is provided.
If there is no risk of collision, the value "0" is provided.
Predicted time to collision
[s]
Numerical Single value (no index)
The remaining time to collision [s] is provided (calculated
from vehicle and object speed).
If there is no risk of collision, the value "-1" is provided.
Attention collision Numerical Single value (no index)
The status of the time-based collision prediction is provided:
● "-2": time-based collision prediction not active
● "-1": time-based collision prediction not available. Possible
reasons: The collision prediction was recently triggered or
the vehicle speed is outside the parameterised range.
● "0": no collision predicted
● "1": collision predicted
Criticality of predicted
collision
Numerical Single value (no index)
The criticality of the predicted collision is provided. 3 warning
levels with different warning times can be set:
● "0": no collision predicted
● "1": warning level 1 with highest criticality (shortest war-
ning time)
● "2": warning level 2 with intermediate criticality
● "3": warning level 3 with lowest criticality (longest warning
time)
Status of the next zone Numerical Single value (no index)
The status of the minimum zone is provided:
● "0": minimum zone free
● "1": minimum zone occupied
Predicted collision speed
[m/s]
Numerical Single value (no index)
The collision speed is provided (calculated from vehicle and
object speed).
If there is no risk of collision, the value "-1" is provided.
