Abstract
A synchronizer system and method allow synchronization of a plurality of rotating parts by determining a measured or calculated starting relative speed of the plurality of rotating parts, and based on the starting relative speed selecting a predetermined synchronizer force profile from among a plurality of candidate profiles for synchronizing the plurality of parts prior to engagement. The selected profile is retrieved and applied to a synchronizer between the plurality of parts to be engaged, and when the relative speed between the plurality of parts to be engaged becomes substantially zero, the plurality of parts can then be engaged to one another.
