CONTROL DEVICE FOR VEHICLE DRIVE SYSTEM Russian patent published in 2018 - IPC B60K6/445 B60K6/547 B60L11/14 B60W10/10 B60W20/00 F16H61/02 

FIELD: machine building.

SUBSTANCE: invention relates to a drive system of a vehicle. Control device for a drive system of a vehicle comprising a power-driven differential unit and the mechanical step-by-step transmission unit comprises an input torque estimation unit that calculates the estimated input torque of the mechanical step-by-step transmission unit based on the motion equation for the differential-electric drive unit. There is also a hydraulic control unit which, while the vehicle is moving in a state where one of the gear positions of the mechanical step-by-step transmission unit is installed, increases the hydraulic pressure of one of the friction clutch of the transmission unit that is not engaged. Pressure increases until the calculated input torque changes by a predetermined amount or more.

EFFECT: pressure of each hydraulic device is determined.
