    • The invention relates to an electropneumatic brake control device (30) for controlling a parking brake of a vehicle with a service brake and a parking brake, comprising an electromagnetic valve device (36) which is controlled by an electronic control device (46) and can be supplied with compressed air from a compressed air storage (8, 10) via a storage connection (28); a parking brake signal connection (48) for inputting parking brake signals output by an electric parking brake signaling device (50); and an air quantity-boosting valve device (42) which is pneumatically controlled by the electromagnetic valve device (36) and which comprises a working outlet (44) that can be connected to a first outlet connection (32) for at least one spring applied brake cylinder, wherein air is removed from said at least one spring applied brake cylinder in order to apply the at least one spring applied brake cylinder and air is supplied in order to release the at least one spring applied brake cylinder. A control air line (52) is provided between an outlet (38) of the electromagnetic valve device (36) and a pneumatic control inlet (40) of the air quantity-boosting valve device (42). The invention provides a pneumatically controlled 2/2-way valve (58) comprising an inlet (60) which is connected to or can be connected to the control air line (52) or the working outlet (44) of the air quantity-boosting valve device (42), an outlet (64) which is connected to a pressure sink (68), and a pneumatic control connection (66) for a stored pressure of the service brake. The pneumatically controlled 2/2-way valve (58) has two positions: a conducting position, which is smaller than a specified threshold value in the event of a stored pressure of the service brake and in which the inlet (60) is connected to the outlet (64), and a blocking position, which is larger than a specified pressure threshold in the event of a stored pressure of the service brake and in which the inlet (60) is blocked from the outlet (64).
    • 电动气动制动控制装置利用行车制动器和驻车制动器来控制车辆的驻车制动。 它包括电磁阀装置,其可以经由存储连接从压缩空气存储器供应压缩空气; 用于输入由电动驻车制动信号装置输出的驻车制动信号的驻车制动信号连接; 以及空气量增压阀装置,其由电磁阀装置气动控制,并且具有可连接到用于至少一个弹簧施加的制动缸的第一出口连接的工作出口。 在电磁阀装置的出口和增压阀装置的气动控制入口之间设置有控制空气管线。 气动二通阀具有可连接到控制空气管线或增压阀装置的工作出口的入口,连接到压力罐的出口和用于 行车制动器的存储压力。 气动二通阀具有两个位置:导通位置,在制动器的存储压力和入口连接到出口的情况下小于指定的阈值,并且阻塞 该位置在制动器的存储压力的情况下大于指定的压力阈值,并且其中入口被阻塞在出口处。
