Abstract (en)
[origin: WO2013007417A1] The invention relates to a monitoring device for at least one sub-unit of a hydraulic brake system and to a method for examining a functional capability of at least one sub-unit of a hydraulic brake system, comprising the steps of detecting at least one pressure variable (p) of a pressure (S1) prevailing in the hydraulic brake system, and comparing the detected pressure variable (p) with a predefined comparative value range ([pO]) (S2), wherein, at least if the detected pressure variable (p) deviates from the predefined comparison ([pO]), a pressure change variable (??) relating to a temporal change of the pressure variable (p) is detected (S4) and the detected pressure change variable (??) is compared with a predefined minimum change variable (???) (S5), and the functional capability is determined, taking into account the comparison of the pressure variable (p) with the predefined comparative value range ([pO]) (S3), and, at least if the detected pressure variable (p) deviates from the predefined comparative value range ([pO]), taking into account the comparison of the pressure change variable (??) with the predefined minimum change variable (???) (S6, S7).
