12.3 VEHICLE SPEED DEPENDENT WHEEL ANGLE LIMITATION

As a risk mitigation method, when using an auto-guidance function, the PVED-
can limit the maximum allowed angle, that the wheels can be moved to, in proportion to the vehicle speed (i.e. the
faster the vehicle goes, the narrower the maximum allowed angle, that the wheel can be moved to, will be).
The range is from 0 to 100 kmph for P3463 and P3467 and from 0 to 89 [°] for P3461, P3465 and P3469.
Important
This function applies to both GPS and GPS2.
These parameters represent the three points on the curve below (Point G, H and I). The auto-guidance algorithm will
make linear interpolation in between each of the three points. The operator is free to move the three points in any
direction, limited by the following rules:

Point G is always specified at Vehicle speed limiting wheel angle = 0 kmph
