Title:
HYDRAULIC CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2019035422
Kind Code:
A
Abstract:
To suppress a pressure of first oil from pulsating.SOLUTION: In a hydraulic control device 10, when it is detected that a pressure of first oil (output pressure of a first pump 20) detected by an output pressure sensor 26 pulsates, a TCU 46 stops driving of a second pump 28 or decreases a rotation number of the second pump 28 as a first operation. Alternatively, when it is detected that the output pressure of the first pump pulsates, the TCU 46 increases the rotation number of the second pump 28 to a rotation number (for example, maximum rotation number) that is higher than a target rotation number as a second operation.SELECTED DRAWING: Figure 1
