摘要： A controller may have a plurality of self-diagnostic functions, each of which is configured for checking a function of an assigned hardware component of the controller. Each of the self-diagnostic functions may have at least one safety limit value, which is configured such that when the at least one safety limit value is exceeded the corresponding hardware component is switched off. Each of the self-diagnostic functions may have at least one quality limit value, the absolute value of which is smaller than an absolute value of the at least one safety limit value. The at least one quality limit value can be configured such that a quality-relevant state can be detected in the assigned hardware component when the at least one quality limit value is exceeded.

摘要： 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.
