Abstract: A method is for operating a vehicle including a steering system having a steering handle and at least one wheel steering angle actuator operatively connected to the steering handle for changing a wheel steering angle of at least one vehicle wheel. The method includes, in a normal operating state, controlling at least one steering functionality depending on an operating parameter correlated with a current vehicle speed, and, in an operational fault state in which an availability of the operating parameter is restricted and/or a failure of the operating parameter is determined, replacing the operating parameter by a replacement parameter correlated to a replacement speed. The method also includes performing a situationally adjusted transition from the operating parameter to the replacement parameter.

Abstract: A system for guiding a vehicle includes first and second operating elements, which are configured to influence a wheel steering angle of the vehicle and are not mechanically coupled to one another. A target steering angle is determined as a function of a sum of steering torques, which is dependent on a target steering torque and actual steering torques of the first and of the second operating elements. The first and second actual steering angles are adjusted as a function of the target steering angles in the respective first and second operating elements. A target wheel steering angle is determined as a function of the target steering angle, wherein the sum of steering angles includes two summands dependent on the first actual steering angle and the second actual steering angle, respectively. The wheel steering angle is adjusted as a function of the target wheel steering angle.

Abstract: A method for operating a steering system of a motor vehicle includes ascertaining a first torque depending on a target steering rack position and depending on the actual steering rack position, ascertaining a second torque depending on a vehicle speed, ascertaining a supporting torque depending on the first and the second torques, and introducing the supporting torque into a steering gear of the steering system.

Abstract: A method for controlling articulation angle during reversing of a vehicle combination, comprising a tractor motor vehicle having at least one trailer, uses a first articulation angle controller, which determines an intended steering lock from at least one steerable wheel of the tractor vehicle and controls the same via a steering actuator of the tractor motor vehicle, in order to achieve a predefined intended articulation angle of the vehicle combination. The rate of change of the articulation angle is limited in such a way that the maximum available setting speed of the steering actuator is sufficient, such that the movement of the at least one trailer follows the intended articulation angle, in particular over a predefined range of speed of travel of the vehicle combination.
