Title:
VEHICLE HYDRAULIC PRESSURE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2016031144
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicle hydraulic pressure control device capable of preventing both a reduction in restarting performance after a mechanical oil pump is stopped and the seizure of a clutch during restarting.SOLUTION: While a mechanical oil pump O/P actuated by a motor-generator MG is stopped, a motor oil pump M/O/P is actuated by a sub-motor S/M. When a hydraulic pressure supplied to a transmission mechanism hydraulic pressure system Sup is equal to or higher than a necessary hydraulic pressure, a selector valve 106 connects a motor oil pump discharge oil passage 105 to a cooling system oil passage 104 for supplying oil discharged from the motor oil pump M/O/P to a cooling/lubrication system Lub of a transmission mechanism. Furthermore, when the hydraulic pressure supplied to the transmission mechanism hydraulic pressure system Sup is lower than the necessary hydraulic pressure, the selector valve 106 connects the motor oil pump discharge oil passage 105 to a second hydraulic pressure supply oil passage 103 for supplying the oil discharged from the motor oil pump M/O/P to the transmission mechanism hydraulic pressure system Sup.SELECTED DRAWING: Figure 3
