Title:
SPEED-CHANGE CONTROL APPARATUS AND SPEED-CHANGE CONTROL METHOD FOR CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2013/132899
Kind Code:
A1
Abstract:
A frictional engagement element control unit is provided with: a target slip rotational speed setting unit for setting a target slip rotational speed for the frictional engagement element; an engaging force control unit for controlling the engaging force of the frictional engagement element so that an actual slip rotational speed of the frictional engagement element corresponds to the target slip rotational speed; and a target slip rotational speed changing unit that sets, when a deviation between the actual slip rotational speed and a first target slip rotational speed is large, a second target slip rotational speed with a small deviation from the actual slip rotational speed, instead of the first target slip rotational speed.
