METHOD AND SYSTEM FOR DETERMINING A RACK FORCE, OPERATING ASSISTANCE METHOD FOR A WORKING DEVICE, OPERATING ASSISTANCE DEVICE AND WORKING DEVICE

摘要

Determining a value (Z) of the rack force (F _ZST) of the rack force (F _ZST), the steering system 15 of the working device 10 'or the vehicle 10 to determine a possible reliable value (Z) for the A method (S) for doing is proposed, the method, Providing a set of rack force models Mi (S1), detecting operating parameters of the basic working device 10 ′ or vehicle 10 and in particular driving parameters Fj (S2), a plurality of Supplying operating parameters or running parameters Fj to the rack force model Mi of (S3), determining a value Zi for the _{rack force F ZST from each rack force model Mi} Step (S4), _{evaluating values (Zi) for the rack force (F ZST} ) (S5), and (a) _{values for the rack force (F ZST} ) from the rack force models (Mi) (Zi) And (b) based on the result of the evaluating step (S5), determining (S6) and providing (S7) the combined result value as the value (Z) for the _{rack force (F ZST ).} do.
