CONTROL DEVICE FOR POWER TRANSMISSION DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To efficiently utilize a power to be supplied to a motor when torque phase compensation control using the motor is executed during the shift of a shift section in a power transmission device for a vehicle equipped with an electric differential section and a shift section.

SOLUTION: Torque phase compensation control is performed by using a motor whose motor output PM(necessary power PM*) necessary for generating necessary torque ΔTINnecessary for torque phase compensation control is smaller between a first motor M1 and a second motor M2 by a torque compensation means 88. Thus, the torque phase compensation control whose power efficiency is more satisfactory is selected when generating the necessary torque ΔTINin torque phase compensation control by using either the first motor M1 or the second motor M2. That is, the efficient battery in an electricity accumulation device 56 which supplies a power to the motor, and less power consumption per unit time is chosen.
