The invention relates to a method for adjusting a pressure setting in a brake system (1) having a pressure application device (3) and an overflow valve (7), comprising the following steps: receiving (10) a pressure demand (30) and determining (11) a pressure demand gradient (32) as a function of the pressure demand (30), determining (12) a volumetric flow demand (33) as a function of the pressure demand gradient (32), and adjusting the pressure setting in the brake system (1), a hydraulic pressure (13) is generated by means of the pressure application device (3), an actual volumetric flow rate (14) of the pressure application device (3) is determined, the relief valve (7) is adjusted on the basis of the pressure demand (30) and on the basis of a difference between the actual volumetric flow rate (14) and the volumetric flow rate requirement (33, 34, 35), a special mode is activated (36) when the pressure demand gradient (32) exceeds a gradient limit value, and the pressure demand gradient (32) is adjusted on the basis of the volumetric flow rate requirement (33, 34, 35). A minimum value (22) of the volume flow rate requirement (33, 34, 35) is set in the special mode according to the last maximum value (21) of the volume flow rate requirement (33, 34, 35), and the special mode is deactivated (37) when the difference between the pressure demand (30) and the system pressure (31) is below a first limit value (39).
本发明涉及一种用于调节制动系统(1)中的压力设置的方法,该制动系统具有压力施加装置(3)和溢流阀(7),该方法包括以下步骤:接收(10)压力需求(30)并且根据压力需求(30)确定(11)压力需求梯度(32),根据压力需求梯度(32)确定(12)体积流量要求(33),藉由压力施加装置(3)产生液压压力(13),确定压力施加装置(3)的实际体积流量(14),基于压力需求(30)且基于实际体积流量(14)与体积流量要求(33,34,35)之间的差来调节溢流阀(7),其中当压力需求梯度(32)超过梯度极限值时,激活(36)特殊模式,基于体积流量要求(33,34,35)的最后的最大值(21)在特殊模式中设置体积流量要求(33,34,35)的最小值(22),并且在压力需求(30)与系统压力(31)之间的差低于第一极限值(39)时,停用(37)特殊模式。
