Title:
OIL SUPPLY DEVICE OF HYBRID VEHICLE
Document Type and Number:
Japanese Patent JP2019089440
Kind Code:
A
Abstract:
To provide an oil supply device of a hybrid vehicle, that is capable of reducing surplus flow of oil and decrease loss of an oil pump.SOLUTION: An HEV-CU 50 and a TCU 70 estimate a respective heating value from a respective operation state of a first motor generator 11 and a second motor generator 12, calculate a respective necessary flow rate from the heating value, and obtain a target drive amount of a first electromagnetic valve 31 which adjusts an oil amount to be supplied to the first motor generator 11 from the necessary flow rate and a second electromagnetic valve 32 which adjusts an oil amount to be supplied to the second motor generator 12, in order to drive the first electromagnetic valve 31 and the second electromagnetic valve 32 respectively according to the target drive amount. Further, the HEV-CU and the TCU drive a third electromagnetic valve 33 so as to switch between a total discharge state and a half-discharge state of an oil pump 21, on the basis of a rotation frequency of the oil pump 21 and the necessary flow rate of the first motor generator 11 and the second motor generator 12 respectively.SELECTED DRAWING: Figure 1
