Abstract

A method for controlling a polyphase electric power steering motor. A method for controlling a polyphase electric power steering motor of a motor vehicle, said motor comprising a stator (1) having: an electric winding connected in star configuration and defining the electrical phases (12, 14, 16) of the stator (1), electric relays (22, 24, 26) for opening said phases (12, 14, 16), and at least one impedance (30, 32, 34, 36) interposed between the control electrode of at least one electric relay (22, 24, 26) and the neutral of the electric winding, in which the open state of the electric relays (22, 24, 26) is controlled by means of an electric current flowing through said impedance, said electric current being determined by a current generator powered by an isolated power supply.
