Abstract
A steer-by-wire steering system for a vehicle, having a steering handle, a steering gear actuator mechanically decoupled from the steering handle, a steering sensor which detects a rotational position and/or a rotational movement of the steering handle as a steering command, an electronic control unit which, as a function of the detected steering command, activates the steering gear actuator to set a vehicle wheel steering angle (α), and a hand actuator activatable by the control unit, which generates different types of haptic feedback (R1, R2, R3) for the driver on the steering handle, namely a haptic steering feedback (R1) in which a steering counter torque is applied to the steering handle, a roadway feedback (R2), which correlates with a roadway-side disturbance excitation acting on the vehicle, and a warning feedback (R3), which informs the driver of a fault in the steer-by-wire steering system.
