The invention relates to an electropneumatic valve arrangement (1) for actuating a parking brake function of an electropneumatic brake system (102) of a utility vehicle (100), comprising a pilot control unit (8) which regulates a pilot control pressure (pSV) as a function of an electronic parking brake signal (SFB) and which is designed to be self-held, wherein the pilot control pressure (pSV) can cause the parking brake pressure (pBP) to be controlled at the at least one spring accumulator connection (21), or the pilot control pressure can be controlled as the parking brake pressure. Furthermore, the valve arrangement has an emergency release connection (38) with an emergency release path (39) for selectively introducing an emergency release pressure (pSN), which causes the parking brake pressure (pBP) to be controlled at the at least one spring accumulator connection (21). The invention also relates to a method and to a commercial vehicle.
本发明涉及一种用于对商用车辆(100)的电动气动制动系统(102)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),先导控制单元依赖于电子驻车制动信号(SFB)调控出先导控制压力(pSV),并且先导控制单元被构造成自保持的,其中,先导控制压力(pSV)能够引起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)或者能够调控出先导控制压力作为泊车制动压力。此外,阀设施具有紧急释放联接端(38),紧急释放联接端具有用于有选择地引入紧急释放压力(pSN)的紧急释放路径(39),紧急释放压力引起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)。本发明还涉及一种方法以及一种商用车辆。
