Title:
LUBRICANT-FLOW-RATE CONTROL DEVICE FOR AUTOMATIC TRANSMISSION, AND LUBRICANT-FLOW-RATE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2014/147920
Kind Code:
A1
Abstract:
An integrated controller calculates, on the basis of a rotational speed difference in a friction element corresponding to a selected position, a required lubricant flow rate required to lubricate the friction element corresponding to the selected position. Immediately after switching between a forward travel position and a reverse travel position is performed, the integrated controller increases the flow rate of lubricant to be supplied to the friction element corresponding to the selected position, and supplies, to the friction element corresponding to the selected position, the lubricant at a flow rate greater than the required lubricant flow rate.
