Electrical power steering – modelling and bench testing

Aleksander Kuranowski

Abstrakt

The article presents a dynamic model of an electric device supporting the steering system of a passenger car; the model was verified through a series of bench tests. The research object was an integrated electric power steering system (EPS) mounted on a steering column and cooperating with a steering gear. The results of the theoretical analysis were compared with the results of tests performed on a specially built research bench fully reflecting the work of assistance in the car. A satisfactory level of agreement between the results of the model tests and the bench tests was obtained.

Keywords: EPS, modelling, bench tests

Streszczenie
W artykule przedstawiono zweryfikowany testami laboratoryjnymi dynamiczny model elektrycznego urządzenia wspomagającego kierownicę. Przedmiotem badań było zintegrowane elektryczne urządzenie wspomagające kierownicę (EPS) zamontowane na kolumnie kierownicy. Wyniki analizy teoretycznej porównano z wynikami testów przeprowadzonych na specjalnie zbudowanym stanowisku badawczym w pełni odzwierciedlającym pracę urządzenia w samochodzie. Uzyskano zadawalającą zgodność między wynikami badań stanowiskowych a wynikami analiz teoretycznych.
