  • Patent number: 11448275
    Abstract: The present disclosure relates to a method for operating a vehicle brake. The vehicle brake includes a hydraulic service brake having an actuating piston, which for generating a first braking force component is movable, under the action of a hydraulic pressure, into an actuating position in which the actuating piston presses a friction lining against a rotatingly supported brake disc, and an electric parking brake, with an actuating element, that is designed to build up a second braking force component that acts on the brake disc. The method includes ascertaining the hydraulic pressure, determining a first braking force component, establishing a second braking force component to be set by means of the parking brake, based on the first braking force component and a desired total braking force, and establishing a position of the actuating element of the parking brake to be set.

  • Patent number: 11400900
    Abstract: An aircraft or other vehicle includes a system and method for selectively allocating which friction brakes of a plurality of friction brakes are utilized in response to a braking demand. Said differently, the present disclosure provides a system and method that includes dynamically switching which friction brakes of a plurality of friction brakes are active (e.g., in use) at a given time in response to a braking demand. This dynamic switching may not only be based on the received braking demand (e.g., from a pilot or auto-braking module), but may also be based on one or more of the following: respective measured brake parameters of the plurality of friction brakes (e.g., temperature, extent-of-wear), aircraft parameters, external parameters, and respective calculated brake conditions.

  • Patent number: 11400898
    Abstract: When a drawbar is inserted into a coupling hole, which is a necessary task to couple a towbar to a tractor, a brake device switches from a braking state in which a braking force is applied to each front wheel to a non-braking state in which the front wheel is released from the braking force. When the drawbar is removed from the coupling hole, which is a necessary task to uncouple the tractor from the towbar, the brake device switches from the non-braking state to the braking state.
