  • Publication number: 20230196609
    Abstract: A method for determining a pose of an object relative to a vehicle, wherein the object has at least three markers, wherein the object is detected by at least one camera, the method including detecting the markers with the camera and generating an image, wherein one marker display is assigned to each of the markers, determining marker positions and/or marker vectors of the markers, determining a transformation matrix as a function of the marker positions and/or the marker vectors and the marker displays, wherein the transformation matrix maps the markers onto the marker display in the image, and determining an object plane formed by the markers in a second coordinate system as a function of the transformation matrix, wherein the second coordinate system is fixed relative to the vehicle, wherein the markers are spatially extended and assigned to planar marker displays in the image.

  • Publication number: 20230158851
    Abstract: 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.

  • Patent number: 11623635
    Abstract: A working vehicle (2) 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 (4), an electronically controllable brake system (6), a sensor arrangement (8) for measuring rotational movements or rotational oscillations about at least one of three reference axes, and an electronic control device (10) for evaluating sensor data and for activating the drive motor (4) or the brake system (6). A data storage (50) 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.

  • Patent number: 11577702
    Abstract: 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.

  • Publication number: 20210016611
    Abstract: A tire pressure control device (1) of an off-road vehicle is configured for changing tire pressures of vehicle wheels (2a, 2b, 3a, 3b) of at least one vehicle axle (2, 3). Each pneumatic tire has a pressure-controlled wheel valve (4a, 4b, 5a, 5b) which is pneumatically connected to a control pressure line (S1, S2) and to a supply pressure line (V1, V2). The control pressure lines (S1, S2) and the supply pressure lines (V1, V2) are configured to be pneumatically connected to a compressed air supply device (6) and to be controlled by an electronic control unit (10) The actuation of the wheel valves (4a, 4b, 5a, 5b) takes place axle by axle via control valves (15, 16), and the compressed air supply of the vehicle wheels (2a, 2b, 3a, 3b) is carried out by side via supply valves (11, 12).

  • Publication number: 20200172070
    Abstract: An electrohydraulic brake system of an off-road vehicle includes a first hydraulic brake circuit for a first vehicle axle; a second hydraulic brake circuit for at least one second vehicle axle; a respective wheel brake for each vehicle wheel per vehicle axle; an electronic control unit having a brake force distribution function; a brake signal generator; at least one central brake force distribution valve per brake circuit, a signal input of the control unit for registering a braking signal of the brake signal generator; and at least one signal output of the control unit per brake force distribution valve. A brake pressure for applying a hydraulic pressure fluid to the brake cylinders of the wheel brakes on the respective vehicle axles can be fed to the respective brake circuit by the control unit in conjunction with the central brake force distribution valve and the brake signal generator.
