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.

System and method for guiding a vehicle, and vehicle comprising said system

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.

Method for operating a steering system, and steering system

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.

Method for controlling an articulation angle

The invention relates to a method for assisting a driver in maneuvering a motor-vehicle combination () comprising, as vehicles, at least one tractor motor vehicle () and at least two trailers () coupled thereto, wherein a target articulation angle (&#x3b3;) at least between two of the vehicles () is externally specified and is adjusted by means of at least one steering actuator () of at least one of the vehicles (). The method comprises at least the following steps: a) dividing the motor-vehicle combination () into at least two sub-combinations () in such a way that adjacent vehicles () form a sub-combination () in pairs, in which sub-combination a first vehicle is used as a trailer unit () and a second vehicle is used as a tractor vehicle unit (), at least virtually; b) repeatedly determining a target angle (&#x3b1;, &#x3b3;, &#x3b3;) for a number of consecutive sub-combinations () from a specified target articulation angle (&#x3b3;, &#x3b3;) between the tractor vehicle unit () and the trailer unit (), beginning with the sub-combination () whose target articulation angle (&#x3b3;) was specified externally, wherein: &#x2014;the determined target angle is adjusted as a target steering angle (&#x3b1;) for the tractor vehicle unit () of the sub-combination () by means of the at least one steering actuator () of the associated vehicle () if the tractor vehicle unit () has the at least one steering actuator (), or &#x2014;the determined target angle is specified as the target articulation angle (&#x3b3;) for the next sub-combination ().

Method for assisting a driver in maneuvering a motor-vehicle combination

A method for controlling the articulation angle of a big rig, in which a first articulation angle control unit, which determines and controls a target wheel angle of at least one steerable wheel of the tractor unit so as to achieve a predefined target articulation angle of the big rig, is combined with a further articulation angle control unit for controlling the articulation angle with the first articulation angle control unit.

Method and device for controlling the articulation angle of a big rig

A method for remotely controlling a motor vehicle, wherein the motor vehicle comprises a steering system and a drive train, which can both be electronically actuated by control means of the motor vehicle and by way of which the motor vehicle can be driven automatically. The control means of the motor vehicle have a wireless communication link to the touchscreen device so that automatic driving of the motor vehicle can be remotely controlled by way of the touchscreen device.

Method for controlling the driving of a motor vehicle and drive control system

A method for remotely controlling a big rig comprises a tractor unit and one or more trailers coupled to the tractor unit, wherein the tractor unit comprises a drive train which can be electronically actuated by the control of the tractor unit and by way of which the tractor unit can be driven automatically. The control of the tractor unit have a wireless communication link to a touchscreen device so that automatic driving of the big rig can be remotely controlled by way of the touchscreen device during which at least one articulation angle between a longitudinal axis of the tractor unit and a longitudinal axis of the trailer is continuously regulated.
