Abstract
本发明涉及针对用于车辆(200)的、尤其是商用车辆(202)的能电子控制的气动制动系统(204)的故障制动功能(FN)的故障安全阀单元(1)，其中，制动系统(204)具有至少一个控制单元(410)，并且故障安全阀单元(1)具有：‑提供第一压力(p1)的主接口(20)和故障制动接口(22)，‑被构造为单稳态阀的故障制动阀(40)，故障制动阀能由控制单元(410)或外部控制单元(418)控制，并且故障制动阀被构造成，‑在打开位置(40A)中将主接口(20)和故障制动接口(22)气动连接以用于在故障制动接口(22)处调控出故障制动压力(pN)。根据本发明设置的是，‑在控制单元(410)的错误状况(FF)和/或电力故障(FS)和/或诊断状况(FT)中，故障制动阀(40)处于打开位置(40A)中，并且‑经由在故障制动接口(22)处提供故障制动压力(pN)通过制动系统(204)来触发对车辆(200)的故障制动(BA)，其中，‑主接口(20)与驻车制动功能(FFS)气动连接，以用于接收被调控出的驻车制动压力(pFS)或由该驻车制动压力推导出的压力(pFS‘)作为第一压力(p1)。

The invention relates to a fail-safe valve unit (1) for a fail-safe Function (FN) of an electronically controllable pneumatic brake system (204) for a vehicle (200), in particular a commercial vehicle (202), wherein the brake system (204) has at least one control unit (410), and the fail-safe valve unit (1) has a main interface (20) and a fail-safe interface (22) which provide a first pressure (p 1), -a fail-safe valve (40) which is configured as a monostable valve, which can be controlled by the control unit (410) or an external control unit (418), and which is configured, in an open position (40A), to pneumatically connect the main interface (20) and the fail-safe interface (22) for regulating a fail-safe pressure (pN) at the fail-safe interface (22). According to the invention, it is provided that in the event of an error condition (FF) and/or an electrical Fault (FS) and/or a diagnostic condition (FT) of the control unit (410), the fault brake valve (40) is in the open position (40A), and that a fault Brake (BA) for the vehicle (200) is triggered by the brake system (204) by providing a fault brake pressure (pN) at the fault brake interface (22), wherein the main interface (20) is pneumatically connected to the parking brake function (FFS) for receiving the regulated parking brake pressure (pFS) or a pressure (pFS') derived from the parking brake pressure as the first pressure (p 1).
