Document Type and Number:
WIPO Patent Application WO/2019/039295
Kind Code:
A1
Abstract:
This estimation apparatus for a synchronization device provided with a dog gear, a synchronizing sleeve, and a synchronizer ring, is provided with: a stroke sensor that can detect a shift stroke amount of the synchronizing sleeve; a stroke difference calculation unit that calculates a stroke difference which is a difference between a shift stroke amount at the start of synchronization and a shift stroke amount at the end of a gear-in operation on the basis of the detection value of the stroke sensor acquired during the gear-in operation; and an abrasion estimation unit that estimates an abrasion amount or an abrasion degree of a synchronizing element of the synchronization device on the basis of the stroke difference.
