Abstract: An electropneumatic valve unit (100, 200) for a vehicle brake system has a plurality of valve sections (102; 104; 106; 108; 204; 206) integrated into a single valve housing (101). The plurality of valve sections (102; 104; 106; 108; 204; 206) includes a front axle redundancy section (102) configured to provide a redundant supply or control pressure for controlling brakes associated with a front axle of a vehicle or a tractor, and a trailer control section (104; 204) for providing supply and/or control pressure to a trailer connected to the tractor. The redundant supply or control pressure for controlling brakes associated with the front axle of the vehicle at the front axle redundancy section (102) is derived from an output pressure of the trailer control section (104; 204).

Abstract: A method for controlling a brake system in the case of leaks is provided. The brake system has a mechanically actuable master brake cylinder, which is connected to a first partial reservoir of a brake fluid vessel, and has an electric linear actuator, which is connected to a second partial reservoir of the brake fluid vessel. The master brake cylinder and the linear actuator are connected via an electrically closable circuit isolating valve. In order to protect the brake fluid, in the event of a leak during a transition to a standby state, the linear actuator is activated to take a brake fluid volume out of the first partial reservoir via the open circuit isolating valve and to displace it into the second partial reservoir.
