10.4 VEHICLE SPEED DEPENDENT QUICK STEER

The PVED-CLS has 5 different steering wheel programs, where the operator can setup the wanted number of turns
lock-to-lock, on the steering wheel at a given vehicle
The range is from 1 to 100 kmph for the parameters named
and from 10 to 800 dec [Resolution = 0.01; 1turn = 100] for parameters named
.
These parameters represent the three points on the curve below (Point A, B and C). The steering wheel control
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 A is always specified at Vehicle speed = 0 kmph
