The invention relates to an electropneumatic trailer parking brake system (102) for a trailer (201), comprising an electropneumatic trailer parking brake module (100) which is designed to release or engage the trailer parking brake system (102) as a function of an actuation signal (SB), the invention relates to a parking brake device (10) for a vehicle, comprising a reserve connection (20) for receiving a reserve pressure (pV), a parking brake connection (21) for coupling a parking brake cylinder (24), a main valve unit (50) for controlling a spring accumulator pressure (pF) at the parking brake connection (21) as a function of a control pressure (pS), and a pilot control valve assembly (70) providing the control pressure (pS). According to the invention, an electronic control unit (300) is provided, which is designed to receive an operating signal (SB) in the form of an electrical operating signal (SBE) for releasing or engaging the electropneumatic trailer parking brake system (102) and to provide an electrical switching signal (S, S1, S2) to the pilot control valve assembly (70) as a function of the electrical operating signal (SB), the pilot control valve assembly (70) is designed to provide a control pressure (pS) in dependence on an electrical switching signal (S, S1, S2).

    本发明涉及一种用于挂车(201)的电动气动挂车驻车制动系统(102),其包括电动气动挂车驻车制动模块(100),电动气动挂车驻车制动模块被设计成用于依赖于操作信号(SB)释放或挂入挂车驻车制动系统(102),并且具有:用于接收储备压力(pV)的储备接口(20)、用于联接驻车制动缸(24)的驻车制动器接口(21)、用于依赖于控制压力(pS)调控出驻车制动器接口(21)处的弹簧蓄能器压力(pF)的主阀单元(50)、提供控制压力(pS)的先导控制阀组件(70)。根据本发明设置电子控制单元(300),其被设计成接收电操作信号(SBE)形式的操作信号(SB),用以释放或挂入电动气动挂车驻车制动系统(102),并且依赖于电操作信号(SB)将电切换信号(S、S1、S2)提供给先导控制阀组件(70),其中,先导控制阀组件(70)被设计成用于依赖于电切换信号(S、S1、S2)提供控制压力(pS)。
