Aux Config - Mini-Steering Wheel - Danfoss PVED-CLS User Manual

ENGINEERING TOMORROW
•
The absolute value of the auxiliary steering device related closed loop error calculated by difference
between calculated wheel angle set-point and actual wheel angle is less than or equal to the value
specified by parameter P3732 i.e. AUX joystick - Max closed loop error for engaging closed loop
joystick steering
If all these conditions are satisfied then the transition to AUX close loop mode is performed.
11.2.3 AUX Config – Mini-steering wheel
For mini-steering wheel, the PVED-CLS detects that the mini-steering wheel is used when both the threshold
P3646 and P3719 are being exceeded, and will then perform a transition to AUX-program.
As a risk mitigation method, disengage the AUX-program and return to STW mode (only hydraulic steering or
faststeering) is allowed by activating/turning the steering wheel. When driving off-road, e.g. on bumpy ground,
too high sensitivity of the SASAIID sensor may cause unintended disengage of AUX steering. In order to allow
small movements of the steering wheel without disengaging the AUX-program, appropriate threshold values
should be written in P3583 and P3584.
The PVED-CLS detects that the steering wheel is in use when both the threshold P3583 and P3584 are being
exceeded. In order to allow the steering device change to AUX mini wheel, the steering wheel shall not be in use
i.e. the absolute steering wheel velocity shall be lower than or equal to STW in use – Velocity threshold (P3583).
Important
The same "steering wheel in use"-algorithm is used for Auto-guidance-steering programs, hence the same rules are used
to perform a transition to the Auto-guidance-program.
