11.4 OPEN LOOP MINI-WHEEL – VEHICLE SPEED DEPENDENT FAST-STEERING
The PVED-CLS has five different open loop mini-steering wheel programs, where the desired number of turns lock-to-
lock on the mini-steering wheel at a given vehicle speed (i.e. "Fast-steering") can be setup.
The range is from 1 to 100 km/h for the parameters named "AUX mini-steering 1,2,3,4,5 - Vehicle speed @ Point K,L"
and from 10 to 800 dec [Resolution = 0.01; 1turn = 100] for parameters named "AUX mini-steering 1,2,3,4,5 - No of turns
@ Point J,K,L".
These parameters represent the three points on the Figure 50 (Point J, K and L). The Open Loop Mini-steering wheel
control 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 J is always specified at Vehicle speed = 0 km/h
•
Point L "No of turns" is valid for Point L "Vehicle speed" and vehicle speeds above Point L "Vehicle speed"
• Point J "No of turns" ≤ Point K "No of turns" ≤ Point L "No of turns"
•
Point L "Vehicle speed" > Point K "Vehicle speed" > Point J "Vehicle speed"
