The invention relates to an electropneumatic assembly (1) for an electronically controllable pneumatic brake system (204) of a utility vehicle (202), comprising: a reserve interface (4) for receiving a reserve pressure (pV); at least one redundant brake pressure connection (8) for providing a redundant brake pressure (pR1) for a first axle (A1) and/or trailer of the vehicle (200); a fail supply interface (10) for providing a fail supply pressure (pAV) limited with respect to and lower than the reserve pressure (pV); and a fail relief valve assembly (14) which is connected to the fail supply connection (10) and to the redundant brake pressure connection (8) and which has a fail brake valve (16) which is designed as a monostable valve and which can be switched in the event of a failure in order to control the redundant brake pressure (pR1) at the redundant brake pressure connection (8) on the basis of the fail supply pressure (pAV). The invention also relates to an electronically controllable pneumatic brake system (204), a method and a vehicle (200).
本发明涉及用于商用车辆(202)的能电子控制的气动制动系统(204)的电动气动的结构单元(1),所述电动气动的结构单元具有:储备接口(4),其用于接收储备压力(pV);至少一个冗余制动压力接口(8),其用于为车辆(200)的第一车桥(A1)和/或挂车提供冗余制动压力(pR1);故障供应接口(10),其用于提供相对于储备压力(pV)受限且低于该储备压力的故障供应压力(pAV);以及与故障供应接口(10)和冗余制动压力接口(8)连接的故障安全阀组件(14),该故障安全阀组件具有被设计为单稳态阀的故障制动阀(16),该故障制动阀能在故障情况下切换,以便基于故障供应压力(pAV)在冗余制动压力接口(8)处调控出冗余制动压力(pR1)。本发明还涉及能电子控制的气动制动系统(204)、方法以及车辆(200)。
