The invention relates to a method for providing vehicle steering support by differential wheel braking, the vehicle comprising: at least two axles with at least two wheels per axle; a braking system allowing individual braking of the wheels; and means for determining and/or estimating an operator input torque applied on a steering wheel, wherein the vehicle is configured with a positive scrub radius; the method comprising the steps of: identifying a need for steering support; determining a braking value required for achieving the needed steering support based on an integration of a function of at least one input value (T) related to a determined or estimated operator input torque; and controlling the braking system based on the determined braking value.

The invention relates to a positioning system for a mobile unit with a reference localization unit, through which a first reference position can be captured at a first point in time and a second reference position of the mobile unit can be captured at a later second point in time; a capturing unit, through with movement data of the mobile unit can be captured; and a computing unit, through which a calculated second position of the mobile unit can be determined at the second point in time by means of a neural network based on the first reference position and the captured movement data. At least one parameter of the neural network can thereby be adjusted based on a comparison of the second reference position with the calculated second position. The invention further relates to a method for operating a positioning system for a mobile unit, in which a first reference position of the mobile unit is captured at a first point in time. Furthermore, movement data from the mobile unit is captured, and a calculated second position of the mobile unit is determined at the second point in time by means of a neural network based on the first reference position and the captured movement data. A second reference position of the mobile unit is captured at the second point in time, wherein a parameter of the neural network is adjusted based on a comparison of the second reference position with the calculated second position.

A method for adjusting a controller of a transportation vehicle includes receiving transportation vehicle state information and information about a current value of at least one variable controller parameter of the controller, calculating a setpoint value for the variable controller parameter, and outputting the setpoint value for the variable controller parameter. The calculating the setpoint value includes using an artificial neural network based on the transportation vehicle state information and the information about the current value of the variable controller parameter.

A method for variation of steering sensation in a steering arrangement of a vehicle, e.g. a truck, which steering arrangement comprises a steering column () via which rotary motion is transmitted between an operating device (), e.g. a steering wheel (), and a servo device () of the steering arrangement. The method includes the steps of&#x2014;varying the rotational resistance of the steering column () as regards the rotary motion and/or&#x2014;varying the moment of inertia of the steering column () as regards the rotary motion and&#x2014;activating the variation manually via an operator, e.g., the driver of the vehicle, and/or automatically. The invention relates also to a device for variation of steering sensation, a computer program for that purpose, a computer and a vehicle with this program.
