Electrical steering system e.g. pignon electric power steering system, assisting method for motor vehicle, involves adapting calculating unit parameterization based on directions of assisting unit by considering vehicle's life situations

摘要

The method involves detecting a transferring direction of power exerted on an electric motor (46) of an assisting unit for determining driven or driving directions of the assisting unit. Parameterization of a calculating unit (50) is adapted based on the driven or driving directions of the assisting unit by considering different life situations of a motor vehicle. Variable flag information is provided via the unit (50), where the information takes values of 0, 1 or 2 for indicating that the assisting unit is found in a driving state or driven state.
