A method for coupling a semi-trailer with a top plate to a truck tractor with a coupling plate includes: importing a reference height profile assigning a reference gradient to different actual values for the relative height of the chassis to the rear axle of the truck-tractor; changing the relative height such that the coupling plate approaches the top plate; continuously determining actual height values and height gradients while changing the relative height, wherein an actual height value is assigned the currently determined actual height gradient; checking a coupling criterion by comparing a currently determined actual height gradient with the reference gradient, wherein the reference gradient which in the imported reference height profile is assigned to the same actual height value as the currently determined actual height gradient is applied; and, maintaining the relative height when the currently determined actual height gradient deviates from the reference gradient.

Method for coupling a trailer to a towing vehicle, coupling control device and vehicle

A tire pressure control device of an off-road vehicle is configured for changing tire pressures of vehicle wheels of at least one vehicle axle. Each pneumatic tire has a pressure-controlled wheel valve which is pneumatically connected to a control pressure line and to a supply pressure line. The control pressure lines and the supply pressure lines are pneumatically connected to a compressed air supply device and controlled by an electronic control unit. The actuation of the wheel valves takes place axle by axle via control valves, and the compressed air supply of the vehicle wheels is carried out by side via supply valves.

Tire pressure control device for an off-road vehicle

A working vehicle () for use in agriculture is configured for mounting a laterally protruding implement on the vehicle front or vehicle rear. The vehicle has an electronically controllable drive motor (), an electronically controllable brake system (), a sensor arrangement () for measuring rotational movements or rotational oscillations about at least one of three reference axes, and an electronic control device () for evaluating sensor data and for activating the drive motor () or the brake system (). A data storage () stores threshold values for the sensor data. The control device determines characteristic values for the respective rotational movement or rotational oscillation and decides whether a reduction in travel speed is required in view of the threshold values. If true, the travel speed is reduced until the characteristic value reaches or falls below the threshold value.

Agricultural work vehicle and control method

A device and a method for decelerating a vehicle having a front-loading device has a brake system and sensors for measuring the mass and the center of gravity of a load. An electronic evaluation and control unit evaluates the sensor data to determine a maximum brake deceleration in forward travel, in order to prevent the vehicle tilting about the front axle. At least one sensor of the brake system generates a sensor signal in an emergency braking situation for triggering an emergency braking operation, in which the delimitation or reduction of the effective brake pressure in the wheel brake cylinders of the front axle is canceled and, with the exception of an ABS control operation, the full brake pressure is introduced in a controlled manner by way of a primary brake valve into the wheel brake cylinders of the front axle.
