A redundant pneumatic brake control system for use in a vehicle (1) comprising a service brake (12) and a spring brake (11), the redundant pneumatic brake control system comprising an electro-pneumatic parking brake module EPB (13), a first pneumatic connection (15), a second pneumatic connection (16), a pressure control valve PCV (14) and a control device (10). The second pneumatic connection is arranged to connect the EPB to a control port (122) of a pneumatic control module PCM (121) such that the generated EPB pressure regulates a control pressure present at the control port. The control device is configured to perform independent control of the pressure-actuated spring brake and the service brake by alternately controlling the PCV to the open position and the closed position based on a difference in step responses of the first pneumatic connection and the second pneumatic connection while controlling the EPB pressure level.

    一种用于载具(1)中的冗余气动制动控制系统,所述载具包括行车制动器(12)和弹簧制动器(11),所述冗余气动制动控制系统包括电动气动驻车制动模块EPB(13)、第一气动连接部(15)、第二气动连接部(16)、压力控制阀PCV(14)和控制装置(10)。第二气动连接部布置成将EPB连接到气动控制模块PCM(121)的控制端口(122),使得所生成的EPB压力调节控制端口处存在的控制压力。控制装置配置成通过在控制EPB压力水平的同时基于第一气动连接部和第二气动连接部的阶跃响应的差异将PCV交替地控制到打开位置和关闭位置来执行对压力致动的弹簧制动器和行车制动器的独立控制。
