Abstract
A method for controlling a power steering system of a vehicle, having a steering wheel, and an inverter powering an assist motor, when a short-circuit failure is detected between a phase of the assist motor and an electric line of the inverter, wherein it includes:—a configuration step intended to determine, for a magnetic field of the assist motor, a controllable zone and a non-controllable zone, —a step of compensating for a space-average brake torque in the controllable zone.
