Title:
CONTROL DEVICE OF TRANSMISSION FOR VEHICLE
Document Type and Number:
Japanese Patent JP2018004043
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device which can suppress the lowering of hydraulic pressure, in a transmission for a vehicle having a first power transmission mechanism and a second power transmission mechanism having a continuously variable transmission in parallel with each other.SOLUTION: Since timing for starting the boosting control of an engagement-side clutch and timing for starting the boosting control of a continuously variable transmission 24 are not overlapped on each other completely, a large quantity of working oil is prevented from being consumed, and the lowering of hydraulic pressure caused by the lack of a flow rate of the working oil can be suppressed. On the other hand, after the lapse of a prescribed time T1, the boosting control of the continuously variable transmission 24 is started, and the flow rate to be consumed becomes small compared with the case that the engagement control of an engagement-side clutch and the boosting control of the continuously variable transmission 24 are simultaneously started. Therefore, the hydraulic pressure necessary for the boosting control of the continuously variable transmission 24 can be secured.SELECTED DRAWING: Figure 6
