11.3 OPEN LOOP FILTER
As a risk mitigation method, Danfoss wants to avoid unintended spool actuation, etc. when driving on bumpy-ground,
therefore an open loop joystick and open loop mini-steering wheel signal filter has been applied to the PVED-CLS’s
steering wheel control algorithm.
Practically, if open loop mini-steering wheel has been selected as steering type, any mini-steering wheel signals, i.e. where
the steering angle velocity is below the value in P3649, will be disregarded.
Furthermore, if open loop joystick steering type has been selected, any joystick flow commands below the value in P3648
will be disregarded.
