変速制御装置
Document Type and Number:
Japanese Patent JP6617681
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the fuel economy of a vehicle that includes a rotary electric machine and a staged transmission and executes an unmanned automatic operation.SOLUTION: A shift control apparatus, incorporated in a vehicle 100 including a power transmission mechanism 110 functioning as a staged transmission for changing speed of rotary power transmitting from an engine 101 and the like, thus outputting the power toward a drive wheel 109, and rotary electric machines 103, 105 capable of inputting and outputting rotary torque between drive wheel side and engine side, executes switch control of the transmission by adjusting hydraulic supplied to a friction engagement element of the power transmission mechanism, and includes a manned automatic operation mode and an unmanned automatic operation mode. Further, when synchronizing rotation speeds of input side and output side of the staged transmission using the rotary torque of a rotary electric machine during switch control of the transmission, the control apparatus, in the unmanned automatic operation mode, increases regenerative power of the rotary electric machine than that in the manned automatic operation mode and adjusts hydraulic pressure to be supplied to the friction engagement element so as to decrease power consumed by the rotary electric machine.SELECTED DRAWING: Figure 1
