A method for automated guidance of a vehicle along a specified setpoint trajectory at an actual speed, wherein the setpoint trajectory includes geometric trajectory variables, the method including ascertaining an actual deviation of the vehicle from the setpoint trajectory and outputting the ascertained actual deviation and generating manipulated variables such that the vehicle, in the case of automated control of a drive system and/or a braking system and/or a steering system of the vehicle, moves closer to the setpoint trajectory. The method also includes ascertaining whether an undesirable driving state is present when the vehicle moves closer to the setpoint trajectory, wherein the undesirable driving state is ascertained from the specified setpoint trajectory based on the geometric trajectory variable, and, if the presence of the undesirable driving state is identified, automatically controlling the vehicle based on generated stability variables and/or adapting the setpoint trajectory.

A method for controlling a vehicle within a confined site, the method including, following a determination that there is no steering system available in a vehicle that can be controlled by steering control signals generated in automated fashion in order to influence a steering angle of wheels of a steered vehicle axle of the vehicle in automated fashion, specifying a path between a starting area and a specified destination area within the confined site, and generating drive control signals and steering braking control signals such that, during subsequent automated control of a drive system and of a brake system using the control signals, the vehicle moves from the starting area along the path to the specified destination area, and the steering angle varies owing solely to automated control of the brakes of the brake system.

A sensor system, for determining an angular change between a utility vehicle and a coupled vehicle trailer, includes a sensor unit having a wheel mounted so as to be rotatable about an axis, and a rotary encoder connected to the wheel and configured to detect a change in position of the wheel. The sensor system further includes a mount having at least one first fixed part configured to connect the sensor system to the utility vehicle or a part thereof, and at least one movable part connected to the sensor unit and mounted so as to be movable on the fixed part. In addition, the sensor system includes a positioning mechanism configured to provide sprung bearing of the movable part in an operating position such that the wheel of the sensor unit can be moved into contact with a vehicle trailer or a part of the vehicle trailer.

A method for automatic electronic control of a brake system in a vehicle includes reading a brake signal for the automatic electronic control of brakes in the vehicle, wherein requests to be implemented by the brakes are transmitted via the brake signal to bring about automatically requested target vehicle longitudinal dynamics. The method further includes determining a brake pressure distribution indicating a ratio of a front axle brake pressure of a front axle to a rear axle brake pressure of a rear axle, and providing at least a first brake pressure signal of the first electronic control unit to at least a first electropneumatic control device, taking into account the braking request signal and the brake pressure distribution for controlling the front axle brake pressure and the rear axle brake pressure, and receiving the brake pressure distribution at a second electronic control unit and storing the detected brake pressure distribution.

A method for determining unstable behavior of a trailer of a vehicle combination, the vehicle combination having N members, one of the members being a tractor vehicle and at least one further member being the trailer, the unstable behavior of the trailer being determined depending on a driving-dynamics actual characteristic variable of the tractor vehicle, includes: determining at least one driving-dynamics actual characteristic variable of the trailer, the at least one driving-dynamics actual characteristic variable characterizing a current driving-dynamics state of the trailer and following from a measurement by at least one sensor in the trailer; and determining at least one driving-dynamics target characteristic variable of the trailer, the at least one driving-dynamics target characteristic variable following from the at least one driving-dynamics actual characteristic variable of the tractor vehicle by using a kinematic model depending on geometric characteristic variables of the vehicle combination.

A method for performing an evasive maneuver with a commercial vehicle-trailer combination includes ascertaining that a collision between the commercial vehicle-trailer combination and a collision object is impending. The method further includes determining an evasion trajectory by which the commercial vehicle-trailer combination can evade the collision object without coming into contact with the collision object, determining a desired steering angle based on the evasion trajectory and activating an active steering system of the commercial vehicle-trailer combination in dependence on the determined desired steering angle such that the commercial vehicle-trailer combination moves along the evasion trajectory from a starting traffic lane to a target traffic lane so as to perform the evasive maneuver. The method additionally includes determining a desired vehicle deceleration and initiating an electronic braking system of the commercial vehicle-trailer combination in dependence on the desired vehicle deceleration so as to brake the commercial vehicle-trailer combination.

A method for controlling a vehicle when driving on a bend, includes determining bend information, wherein the bend information characterizes a further course of the bend in a direction of travel after a current position of the vehicle, determining predicted lateral acceleration values based on the bend information, wherein each of the predicted lateral acceleration values indicates a lateral acceleration predicted to act on the vehicle at a respective one of a plurality of future positions over the further course of the bend, and determining the probability of overturning at the future positions based on the predicted lateral acceleration values by comparing the predicted lateral acceleration values with a lateral acceleration limit value. A roll stability control system outputs a reduced deceleration request if the predicted lateral acceleration values undershoot the lateral acceleration limit value at least in certain regions.

A method for determining, by a utility vehicle having a trailer coupling, an articulation angle between the utility vehicle and a coupled vehicle trailer includes determining, with a model, a modelled value of the articulation angle or an articulation angle change. The method further includes determining, with a sensor unit, a measured value of an articulation angle or of an articulation angle change, and deriving, from the measured value, a correction value. The method additionally includes correcting the modelled value as a function of the correction value, and outputting the corrected modelled value as an output value of an articulation angle.
