Future power-steering systems for full steer-by-wire functionality and low fuel consumption

Zukünftige verbrauchsarme Servolenkungen für vollständige Steer-By-Wire-Funktionalität

  • 93 Accesses

Abstract

Present hydraulic power-steering systems do not meet the requirements on future steering systems anymore. Increasing demands on agility, ride comfort and ride stability as well as stricter restrictions on the fuel consumption demand new approaches. This article describes the essential requirements on future power-steering systems from BMW’s point of view. An analysis shows for which vehicle classes and for which functionalities these requirements cannot be fulfilled by present systems. At the end of this article, concepts for new power-steering systems are proposed which could also cover these areas in the future.
