Abstract
Methods for providing steering assistance for an electromechanical steering system having a redundant control unit with a primary and a secondary control path. Respective primary and secondary control paths each have a computing unit, gate driver module, and power module. The method includes detecting an applied steering torque; calculating a primary and secondary motor target torque in the primary computing unit as a function of the applied steering torque; transmitting the primary motor target torque to a primary motor controller of the primary computing unit; determining primary motor currents to operate a primary electric motor or a primary winding group of the electric motor in the primary motor controller; transferring the secondary motor target torque from the primary computing unit to a secondary motor controller and determining secondary motor currents for operation of a secondary electric motor or a secondary winding group of the electric motor.
