Abstract
A feedback actuator for a motor vehicle may include a steering adjuster that acts on steered wheels of the motor vehicle and is controlled electronically based on steering commands from a driver of the motor vehicle. The feedback actuator may transmit feedback from a road on which the motor vehicle is traveling to a steering wheel via a steering shaft. Further, the feedback actuator may have a preloaded crank drive and an electric motor configured as torque-generating means. The feedback actuator may produce a torque to simulate the feedback of the road, and the torque may be formed by a sum of a torque from the preloaded crank drive applied to the steering shaft and a torque from the electric motor applied onto the steering shaft.
