Title:
CONTROL DEVICE FOR HYBRID VEHICLE
Document Type and Number:
Japanese Patent JP2020066368
Kind Code:
A
Abstract:
To appropriately secure a flow quantity of hydraulic oil when temperature of the hydraulic oil is low, while preventing an increase in output of an electric oil pump.SOLUTION: When traveling in a motor travel mode, if a hydraulic oil temperature THoil is lower than a prescribed oil temperature T1, a first rotating machine MG1 is controlled so as to rotate an MOP 58, so that hydraulic oil is discharged by MOP 58, thus avoiding discharge of the hydraulic oil by EOP 60 in a flow quantity required when the oil temperature is low. On the other hand, if the hydraulic oil temperature THoil is not lower than the prescribed oil temperature T1, a motor 62 is controlled, so that the hydraulic oil is discharged by the EOP 60. As a result, driving of the MOP 58 by the first rotating machine MG1 involving a rise in engine rotation speed Ne is limited to when the oil temperature is low, thus suppressing deterioration of efficiency. Accordingly, it is possible to appropriately secure a flow quantity of the hydraulic oil when the hydraulic oil temperature THoil is low, while preventing an increase in the output of EOP 60.SELECTED DRAWING: Figure 8
