The invention relates to an electronically controllable pneumatic brake system (204) for a commercial vehicle (202), comprising a first control unit (410) for a main system (B1) and a second control unit (420) for a first backup level (B2), and a monostable fail-safe valve unit (1), which pneumatically connects a main connection (20) providing a first pressure (p1) and a fail-safe connection (22), wherein the fail-safe valve unit (1) is connected to the two control units (410, 420) and is in the event of an error condition (FF), a supply failure (SF) and/or a diagnostic condition (FD) of the control units (410, 420). In order to provide a fail brake pressure (pN) for triggering a fail brake (BA), the fail brake connection (22) is connected upstream of a functional pneumatic unit (430) of the main system (B1) and/or the first backup level (B2) to the main system and/or the first backup level such that both the front axle service brake actuators (440a, 440b) and the rear axle service brake actuators (442a, 442b, 442c, 442d) are loaded with a brake pressure (pBVA, pBHA), in this way, a fail brake (BA) is achieved.

    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),其具有用于主系统(B1)的第一控制单元(410)和用于第一后备层级(B2)的第二控制单元(420)、以及单稳态的故障安全阀单元(1),故障安全阀单元将提供第一压力(p1)的主接口(20)和故障制动接口(22)气动连接起来,其中,故障安全阀单元(1)与两个控制单元(410、420)连接并在控制单元(410、420)的错误情况(FF)、供电故障(SF)和/或诊断情况(FD)时。为了提供故障制动压力(pN)来触发故障制动(BA),故障制动接口(22)在主系统(B1)和/或第一后备层级(B2)的功能上的气动单元(430)的上游与主系统和/或第一后备层级连接,使得不仅前桥行车制动执行器(440a、440b)而且后桥行车制动执行器(442a、442b、442c、442d)都被加载制动压力(pBVA、pBHA),以用于实现故障制动(BA)。
