  • Patent number: 10562510
    Abstract: A method for operating a vehicle brake system, including: classifying a fault signal, indicating a fault of an electronic actuating device of the brake system, the actuating device outputting a brake pressure for a brake of the vehicle in a normal operating mode and a pneumatic actuating device for outputting the brake pressure in a backup operating mode, as a fault signal of a first fault category if the fault is a fault in which a switchover from the electronic actuating device afflicted with the fault to the pneumatic actuating device leads to an improvement in the outputting of the brake pressure; and switching from the electronic actuating device to the pneumatic actuating device, to output the brake pressure using the pneumatic actuating device, if the fault signal is a fault signal of the first fault category.

  • Patent number: 10549740
    Abstract: A pressure-limiting valve includes a housing having a piston, a pressure-limiting adjusting spring, at least one inlet and at least one outlet. The piston can assume an open position in which the inlet and the outlet are connected to each other, and at least one closed position in which the inlet and the outlet are separated from each other. The piston has a first piston ring with a sealing surface and a second piston ring. In the closed position, the sealing surface is drawn against a housing projection in a sealing manner by a pneumatic force which acts on the second piston ring and is directed against the force of the pressure-limiting adjusting spring. A pneumatic passage in the piston which implements a safety valve function can be sealed by a spring-loaded safety valve body arranged on a side of the second piston ring that is opposite the outlet.
