VEHICLE SPEED DEPENDENT FLOW COMMAND LIMITATION

GPS algorithm type = GPS v1
Using the auto-guidance function, the PVED-CLS's auto-guidance control algorithm can also limit the maximum allowed
output flow in proportion to the vehicle speed (i.e. the faster the vehicle goes the lower the maximum allowed flow will
be).
Speed range [km/h]:
Range [IR]:
Important
This function applies to both GPS and GPS2.
These parameters represent the three points on the curve below (Point D, E and F). The auto-guidance algorithm will make
linear interpolation in between each of the three points. It is allowed to move the three points in any direction, limited by
the following rules:
•
Point D is always specified at Vehicle speed limited flow = 0 km/h
•
Point F "Max flow" is valid for Point F and vehicle speeds above Point F
• Point D "Max flow" ≥ Point E "Max flow" ≥ Point F "Max flow"
•
Point F "Vehicle speed limited flow" > Point E "Vehicle speed limited flow" > Point D "Vehicle speed limited
flow"
Warning
Failure to comply with the above rules may render this function inoperable or lead to undesirable steering
behavior!
