Abstract

An apparatus is provided for measuring a torque in a force-feedback actuator for a steer-by-wire steering system has a housing element, a control unit, a drive apparatus, and a transmission apparatus to be coupled to a steering device. At least one motion sensor detects a motion of the transmission apparatus relative to the housing element and provide a motion signal resulting from the motion to the control unit. The transmission apparatus is coupled to the housing element by way of at least one reset-reversible adjusting device which has at least one mechanical property. A torque of the transmission apparatus, and thus of a connectable steering device, may be ascertained by the control unit using the at least one mechanical property, which has at least one changing state value during the movement of the transmission apparatus, in combination with the motion signal.
