Title:
HYDRAULIC PRESSURE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/090697
Kind Code:
A1
Abstract:
Provided is a hydraulic pressure control device capable of correcting a control current while taking into account an idle region. This hydraulic pressure control device has an idle region, and is provided with a control unit, and a correction unit which, in cases when the reaction time of the actual pressure to pressure increase control or pressure decrease control exceeds a preset threshold time, corrects a control current at the side at which the flow rate is increased. In cases when a determination unit has determined that the pressure increase control is in the idle region, the correction unit applies, as the threshold time, an idle threshold time set to a value different to that in cases when the determination unit has not determined that the pressure increase control is in the idle region. Furthermore, in cases when the reaction time of the actual pressure to the pressure increase control exceeds the idle threshold time, the correction unit corrects the control current.
