Title:
OIL PRESSURE CONTROL DEVICE FOR VEHICLE AND OIL PRESSURE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2016/152534
Kind Code:
A1
Abstract:
An oil pressure control device is provided with: a mechanical oil pump (O/P) driven by a motor/generator (MG); an electric oil pump (M/O/P) driven by a submotor (S/M); and a line pressure-regulation valve (104). During a transition from a state in which the motor/generator (MG) is stopped and the electric oil pump (M/O/P) is driving, to a state in which the motor/generator (MG) is started and the electric oil pump (M/O/P) is stopped, if the total flow-rate of the discharge flow-rate of the mechanical oil pump (O/P) and the discharge flow-rate of the electric oil pump (M/O/P) becomes greater than or equal to a pressure-regulation limit flow-rate of the line pressure-regulation valve (104), the discharge flow-rate of the electric oil pump (M/O/P) is reduced.
