The invention relates to a method for operating a hydraulic braking system (2), wherein the braking system comprises: a master brake cylinder (6); at least one brake circuit (8) having at least one hydraulically actuatable wheel brake (3); a controllable pressure generating unit (11) which is designed to generate a hydraulic pressure in the at least one brake circuit when a pressure demand occurs; and a controllable auxiliary pressure generating unit (13) which is designed to generate the hydraulic pressure in the at least one brake circuit as an alternative, wherein, when a malfunction is detected in the pressure generating unit, the auxiliary pressure generating unit is controlled in order to generate the hydraulic pressure, and wherein a controllable switching valve (9; 9', 9") is associated with the auxiliary pressure generating unit in order to interrupt or establish a connection to the master brake cylinder. According to the invention: the braking system is monitored for the occurrence of a brake request; and, if a brake request is detected, the second switching valve is controlled in order to interrupt the connection to the master brake cylinder.
用于运行液压制动系统(2)的方法,其中制动系统具有主制动缸(6)和至少一条制动回路(8),制动回路具有:至少一个能液压操纵的车轮制动器(3);能操控的压力产生单元(11),它被构造用于在出现压力要求时在所述至少一条制动回路中产生液压压力;能操控的辅助压力产生单元(13),它被构造用于替代地在所述至少一条制动回路中产生液压压力,在识别出压力产生单元中的功能故障时操控辅助压力产生单元以便产生液压压力,且为辅助压力产生单元分配了能操控的开关阀(9;9’、9’’),以便中断或建立与主制动缸的连接。在此规定,就制动要求的出现对制动系统进行监控,且在检测到制动要求时操控第二开关阀,以便中断与主制动缸的连接。
