Title:
A power transmission control device of vehicles
Document Type and Number:
Japanese Patent JP6239451
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To perform the assist of the torque of an electric motor, and to smoothly perform gear change operation when the gear change operation is performed while performing the synchronization of rotation speed of a transmission input shaft by using the torque of an internal combustion engine, in a power transmission control device which is applied to a hybrid vehicle with an ATM.SOLUTION: At a requirement of gear change to a non-synchronized stage, engagement with a sleeve is released, a neutral stage is obtained, and torque assist by MG torque Tm is performed by OUT connection (t1 to t3). In a joined state of a clutch, EG torque Te is feedback-controlled so that rotation speed Ni of a transmission input shaft coincides with a "synchronization rotation speed" (t3 to t4). In a state that the Te is adjusted to a "synchronization requirement value" so that the synchronization of the Ni is maintained (on and after t4), the Te is temporarily adjusted to a value which is transited to an "engagement release direction" from a "synchronization requirement value" in place of the "synchronization requirement value".
