Abstract
Official abstract text for this publication.
A method for compensating for a delay in a feedback branch of a servo drive, wherein the servo drive is provided for power-steering a vehicle, includes determining the delay. The method further includes arithmetically compensating for the delay by measuring the spatial expansions of a corresponding metal conductor of the servo drive and the feedback branch. The delay takes place due to formation of eddy currents.
First claim
Opening claim text (preview).
1 .- 7 . (canceled) 8 . A method for compensating for a delay in a feedback branch of a servo drive, the method comprising: determining the delay; and arithmetically compensating for the delay by measuring spatial expansions of a corresponding metal conductor of the servo drive and the feedback branch, wherein the delay takes place due to formation of eddy currents, and wherein the servo drive is provided for power-steering a vehicle. 9 . The method as claimed in claim 8 , wherein at least one of the determination and the arithmetic compensation of the delay takes place based on an arithmetic model. 10 . The method as claimed in claim 8 , wherein the delay results due to at least one of a filter, the formation of eddy currents, and a temperature effect. 11 . The method as claimed in claim 10 , wherein the filter is an electronic filter for signal conditioning. 12 . The method as claimed in claim 8 , wherein at least one of the determination and the arithmetic compensation of the delay takes place based on a reference servo drive. 13 . The method as claimed in claim 8 , wherein at least one of the determination and the arithmetic compensation of the delay takes place based on a measurement of one part of the servo drive and one part of the feedback branch. 14 . A steering system for a vehicle comprising: at least one servo drive; a feedback branch for the at least one servo drive; and an electronic control unit configured to perform a method compensating for a delay in the feedback branch of the at least one servo drive, the method including: determining the delay; and arithmetically compensating for the delay by measuring spatial expansions of a corresponding metal conductor of at least one of the servo drive and the feedback branch, wherein the delay takes place due to formation of eddy currents.
