The invention relates to an electropneumatic valve arrangement (1) for actuating a parking brake function of an electropneumatic brake system (202), comprising a pilot control unit (8) and a main valve unit (10), which is adapted to control a parking brake pressure (pBP) at at least one spring accumulator connection (21). The electropneumatic valve arrangement (1) is characterized by having a service brake connection (74) for receiving a service brake pressure (pBB); the safety valve (50) can be switched from a bleed position (54), in which the safety valve (50) connects the control unit (8) to the bleed end (3), into a supply position (52), in which the safety valve (50) supplies the pilot control unit (8) with a reserve pressure (pV) by receiving a safety control pressure (pSS), the safety valve (50) is stopped in a supply position (52) or switched into a deflation position (54) depending on the regulated pressure (pA), and wherein the service brake connection (74) is directly or indirectly connected to the safety valve control connection (50.4) in a fluid-conducting manner. The invention also relates to a brake system (202), a method for controlling a parking brake function and a vehicle (200).

    本发明涉及一种用于对电动气动制动系统(202)的驻车制动功能进行操纵的电动气动阀设施(1),电动气动阀设施具有先导控制单元(8)和主阀单元(10),主阀单元适应性调整成在至少一个弹簧储能器联接端(21)处调控出泊车制动压力(pBP)。电动气动阀设施(1)的特征在于具有用于接收行车制动压力(pBB)的行车制动器联接端(74);和安全阀(50),其中,通过接收安全控制压力(pSS),安全阀(50)能从放气位置(54)切换到供应位置(52)中,在放气位置中,安全阀(50)使所述控制单元(8)与放气端(3)连接,在供应位置中,所述安(50)向先导控制单元(8)供应储备压力(pV),安全阀(50)依赖于调控出的压力(pA)停留在供应位置(52)中或切换到放气位置(54)中,并且其中,行车制动器联接端(74)以导引流体的方式与安全阀控制联接端(50.4)直接或间接连接。本发明还涉及一种制动系统(202)、一种用于控制泊车制动功能的方法和一种车辆(200)。
