SYSTEM AND METHOD FOR MANAGING UPSHIFT FOR SHIFTING GEARS IN AUTOMATIC TRANSMISSIONS

摘要

A system and method for managing an upshift for shifting gears in an automatic transmission (12) of a vehicle includes providing a transmission control unit (62) in communication with an electronic control unit (60) for an engine (14) of the vehicle and providing an automatic transmission (12) having a housing (23), a plurality of gearsets (26) disposed in the housing (23), and a multi-mode clutch module (MMCM) (30) disposed between the housing (23) and at least one gear of one of the gearsets (26) and in communication with the transmission control unit (62). The system and method also include receiving a signal that an upshift of the gearsets (26) begins, beginning closed loop speed control using an off-going clutch (28) of another one of the gearsets (26), and synchronizing speeds between the off-going clutch (28) and the MMCM (30) to complete the upshift from the another one of the gearsets (26) to the one of the gearsets (26).
