Warning
Setting the closed loop gain at a to high level could give unwanted aggressive steering behavior in auto-guidance mode,
especially in combination with a low vehicle speed this could lead to unwanted aggressive steering behavior when
acquiring a line!

12.5 VEHICLE SPEED DEPENDENT FLOW COMMAND LIMITATION

As a risk mitigation method, when using an auto-guidance function, the PVED-
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).
