  • Patent number: 11845503
    Abstract: A motor vehicle has a steering axle, a drive axle and a lift axle having an actuator for lifting and lowering the same. The wheels of the drive axle can be electrically driven, at least in a supporting manner, via an electric machine operable as an electric motor and as a generator, and the wheels can be driven in a generating manner in a recuperation operation. The electric machine is connected to an accumulator and to a control and/or regulation device to control the operation of the lift axle. The device is connected to sensors for wheel slip detection at the drive axle. The device is configured such that, during a recuperation operation, it can send a command to the actuator to lift the lift axle and thereby unload the wheels thereof, if there is wheel slip at least at one wheel of the drive axle.

  • Patent number: 11745698
    Abstract: A vehicle security system is provided for a vehicle having a braking system that includes a parking brake, the parking brake being capable of being switched between a driving position and a braking position. The vehicle security system is configured to secure the vehicle after an accident. The vehicle security system comprises a control unit configured to ascertain an accident of the vehicle and to switch the parking brake of the vehicle into the braking position in response to ascertaining an accident of the vehicle, and a sensor configured to capture and make available first vehicle data that represent a rotary location of the vehicle. The control unit is configured to carry out the ascertainment of an accident on the basis of the first vehicle data.

  • Publication number: 20230191858
    Abstract: A device for coupling a towing vehicle to a trailer vehicle of a vehicle combination, where the towing vehicle has a trailer coupling and the trailer vehicle has a drawbar. A measurement device is configured to measure forces and/or torques between the towing vehicle and the trailer vehicle has a two-part support with a first and second support components. The first support component has at least two measurement arms which extend radially and are symmetrically offset relative to one another. A strain gauge rosette is on each measurement arm. The second support component has counter-arms which extend radially and which correspond in number and arrangement to the measurement arms. The two support components can be attached firmly to one another and to the trailer coupling or to the drawbar. Also disclosed is a measurement-data capture and evaluation unit.

  • Patent number: 11661047
    Abstract: A method includes steps for controlling a pneumatic braking system of a trailer vehicle which is connected to a tow vehicle equipped with a hydraulic or pneumatic braking system. At the start of an actuation of the foot brake valve, an electrical switch is closed or opened, and a switching signal is transmitted to an electronic control unit as a braking start signal for an incipient braking process. A brake value sensor detects a brake value representative of the drivers current deceleration request and transmits the brake value to the electronic control unit as a brake value signal. The brake value sensor is used for determining the incipient braking process, and a backup valve is only deactivated by switching a redundancy valve from an open position to a blocking position if the brake value signal detected by the brake value sensor has reached or exceeded a predefined minimum signal value.

  • 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.

  • Patent number: 11384807
    Abstract: A brake caliper for a vehicle brake is provided. The vehicle brake includes a pair of brake pads, configured to be coupled to the brake caliper, and a disc positioned between the brake pads. The brake caliper includes an adjuster unit mounted to the brake caliper. The adjuster unit includes a gearwheel configured to be rotary driven in a first direction, and an adjuster nut operatively coupled with the gearwheel and configured to be operatively coupled with one of the brake pads, such that a rotational movement of the gearwheel in the first direction is converted, by the adjuster nut, into an axial movement of the brake pad towards the disc. The gearwheel is mounted in the brake caliper such that the gearwheel is axially fixed relative to the brake caliper, while the adjuster nut and the gearwheel are in an axially slidable engagement with respect to one another.
