  • Patent number: 11697403
    Abstract: A device designed for controlling and regulating an electro-pneumatic parking brake circuit includes a manual controller configured to actuate a parking brake via the electro-pneumatic parking brake circuit, the manual controller having a first circuit arrangement and a second circuit arrangement, the first circuit arrangement being a digital, bidirectional circuit arrangement and the second circuit arrangement being an analog circuit arrangement. The device further includes control electronics electrically connected to the manual controller. The first circuit arrangement is connected to the control electronics via a first connection cable and the second circuit arrangement is connected to the control electronics via a second connection cable. The first connection cable is a digital data transmission channel configured to enable a digital data transmission between the digital circuit arrangement and the control electronics.

  • Publication number: 20230182694
    Abstract: The disclosure relates to a method for securing a vehicle, preferably a commercial vehicle, in an emergency braking situation, wherein the vehicle has a vehicle bus system and a braking system, the method having the following steps: monitoring signals on the vehicle bus system; detecting an emergency brake signal provided by a driver assistance system on the vehicle bus system; ascertaining whether the vehicle is at a standstill; bringing a braking device of the braking system into a braking position if a standstill of the vehicle is ascertained. The disclosure also relates to a control unit for a vehicle, a computer program, a braking system for a vehicle, and a vehicle.

  • Patent number: 11292445
    Abstract: A method for operating an electropneumatic parking brake system of a vehicle combination, which includes a tractor vehicle and a trailer vehicle, includes activating, after a parking operation and braking of the vehicle combination, a trailer check function in a standstill state. The trailer check function enables a check as to whether, in the case of a decrease in the braking action of the trailer vehicle, the vehicle combination can be held in a stationary manner solely by way of the braking action of a parking brake of the tractor vehicle. The trailer check function is carried out automatically when a vehicle combination has been braked in a stationary manner independently by way of an automatic parking function.

  • Patent number: 10843673
    Abstract: A method for controlling a compressed air brake system of a vehicle includes outputting an analog driver brake pressure via a brake pressure control line during driver braking by operating a brake pedal, a switching device set in a driver braking position to a brake circuit with at least one ABS stop valve device, a brake line, and a wheel brake. The method additionally includes, in the presence of both driver braking and the external brake demand signal, measuring the driver brake pressure and determining a driver brake pressure value. Furthermore, the method includes forming a combined brake pressure value by adding or superimposing the driver brake pressure value and an external brake pressure value contained in the external brake demand signal, and switching the switching device into the functional position and controlling the combined brake pressure value from the system pressure by actuating the ABS stop valve device.
