11.10 CLOSED LOOP JOYSTICK – VEHICLE SPEED DEPENDENT WHEEL ANGLE LIMITATION
As a risk mitigation method, when using a Closed Loop Joystick function, the PVED-CLS’s Closed Loop Joystick control
algorithm 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 km/h for P3723 and P3724 and from 0 to 89 [°] for P3720, P3721 and P3722.
These parameters represent the three points on the curve below (Point A, B and C). The Closed Loop Joystick-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 A is always specified at Vehicle speed limiting wheel angle = 0 km/h
• Point C “Max wheel angle” is valid for Point C “Vehicle speed limiting wheel angle” and vehicle speeds above
Point C “Vehicle speed limiting wheel angle”
• Point A “Max wheel angle” ≥ Point B “Max wheel angle” ≥ Point C “Max wheel angle”
• Point C “Vehicle speed limiting wheel angle” > Point B “Vehicle speed limiting wheel angle” > Point A “Vehicle
speed limiting wheel angle”
