CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/031451
Kind Code:
A1
Abstract:
Provided is a control device with which it is possible to rapidly implement a state whereby an amount of torque appropriate to demand torque is transmitted to the wheels when a second friction latch device commences slipping. A control device of a vehicle drive device is disposed in order of a first friction latch device, a rotation electric device, and a second friction latch device in a drive transmission path which joins an internal combustion engine with wheels. When changing from a state wherein drive power is transmitted between the rotation electric device and the wheels to at least a state wherein drive power is transmitted between the internal combustion engine and the wheels, the control device gradually lowers oil pressure supplied to the second friction latch device, and when it is determined that the second friction latch device has commenced slipping, carries out a control which increases the oil pressure which is supplied to the second friction latch device by a prescribed oil pressure degree for the supplied oil pressure at the time when it is determined that the slip has commenced.
