Abstract
A control device for operating an electric motor, in particular of a steering system, includes (i) a power electronics system, (ii) a primary driver unit which is intended to actuate the power electronics system in a normal operating state, and (iii) a secondary driver unit which is connected in parallel with the primary driver unit and is intended to actuate the power electronics system in at least one fault operating state in which a malfunction and/or failure of the primary driver unit occurs. The primary driver unit and the secondary driver unit each have an integrated tri-state functionality and the second driver unit is in a high-impedance state in the normal operating state.
