Motor vehicle-hydraulic device`s pressure control device, has digital regulator comprising additional boundary unit, which limits I-portion of control variable signal from time point of actuation of current limiting unit

摘要

The control device (CO) has a digital control circuit (CLC) for providing pressure regulation of volume flow rate of a motor vehicle-hydraulic device (HP) by using a control unit (CV) of an electrical actuator device (EP). A current limiting unit (LI) is provided in a forward path (FP) of the digital control circuit between a digital regulator (PC) and a control unit. The digital regulator has an additional boundary unit (ILI), which limits an I-portion of the control variable signal from a time point (tx) of the actuation of a current limiting unit. An independent claim is also included for a method for controlling pressure of a volume flow rate of a motor vehicle-hydraulic device.
