Abstract
A power transferring gearset includes a gear synchronization controller disposed in communication with a drive gear, a driven gear and a shifting mechanism. In response to detecting a gear engagement command, the gear synchronization controller is configured to determine a rotational speed delta between a rotational speed of the drive gear and a rotational speed of the driven gear and compare the rotational speed delta to a pre-determined speed delta. In response to determining that the rotational speed delta is less than the predetermined speed delta, the gear synchronization controller applies a rotational shutter function to the drive gear to apply a series of clockwise and counterclockwise rotational cycles to the drive gear simultaneously during the axial movement of the shifting mechanism for preventing a blocked condition of the power transferring gearset while establishing the meshed relationship between the shifting and gear teeth.
