The invention relates to a method for operating an electropneumatic brake system (204) of a vehicle (200), preferably a commercial vehicle (202), the brake system (204) comprising a service brake system (510) and a parking brake system (520), the parking brake system (520) comprising at least one spring-loaded brake cylinder (442). According to the invention, the following steps are provided: providing a control signal (S1, S2) by means of the control unit (410, 420) in order to maintain a spring accumulator inflation pressure (pFS) for inflating the at least one spring-loaded brake cylinder (442), and interrupting the provision of the control signal (S1, S2) in the event of an error situation (FF) and/or a supply failure (FS) and/or a diagnostic situation (FT) of the control unit (410, 420) in such a way that the control signal (S1, S2) is supplied by means of the control unit (410, 420) in order to maintain the spring accumulator inflation pressure (pFS) for inflating the at least one spring-loaded brake cylinder (442). The holding of the spring accumulator inflation pressure (pFS) is spontaneously terminated in order to deflate the at least one spring accumulator brake cylinder (442), a spring accumulator fail brake (BAF) of the vehicle (200) is triggered by the parking brake system (520), and the spring accumulator inflation pressure (pFS) is deflated by a service brake deflation function (FBE) of the service brake system (510).
本发明涉及用于运行车辆(200)、优选是商用车辆(202)的电动气动的制动系统(204)的方法,其中,制动系统(204)包括行车制动系统(510)和驻车制动系统(520),其中,驻车制动系统(520)包括至少一个弹簧蓄能式制动缸(442)。根据本发明设置有以下步骤:通过控制单元(410、420)提供控制信号(S1、S2),以用于保持对至少一个弹簧蓄能式制动缸(442)充气的弹簧蓄能器充气压力(pFS),在控制单元(410、420)的错误情况(FF)和/或供电故障(FS)和/或诊断情况(FT)时,通过如下方式中断提供控制信号(S1、S2),即,自发终止对弹簧蓄能器充气压力(pFS)的保持,以用于对至少一个弹簧蓄能式制动缸(442)进行放气,通过驻车制动系统(520)触发车辆(200)的弹簧蓄能器故障制动(BAF),其中,通过行车制动系统(510)的行车制动器放气功能(FBE)来实现对弹簧蓄能器充气压力(pFS)的放气。
