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.
Claims9
A method of synchronizing a plurality of rotating parts for engagement, the method comprising:
- receiving a request for engagement of the plurality of rotating parts to one another;
- determining a starting relative speed of the plurality of rotating parts;
- based on the starting relative speed, determining a time period over which the engagement is to occur and selecting a predetermined synchronizer force profile for synchronizing the plurality of parts prior to engagement;
- retrieving and applying the selected predetermined synchronizer force profile to a synchronizer between the plurality of parts to be engaged for the determined time period over which the engagement is to occur;
- and
- when the relative speed between the plurality of parts to be engaged becomes substantially zero, engaging the plurality of parts to one another.
