Abstract
An improved synchronizer uses a friction element to induce a frictional torque to rotating gear and collar elements. The rotational speeds of the gear and collar elements are electronically monitored by a transmission control unit. When the transmission control unit has determined that the rotational speeds of the gear and the collar are equalized, another control drives the collar to engage the gear.
