Document Type and Number:
WIPO Patent Application WO/2018/043056
Kind Code:
A1
Abstract:
The present invention pertains to a control method for a continuously variable transmission, comprising: supplying oil pressure to a line pressure oil path and a secondary pulley oil chamber by using a source pressure oil pump (100); and controlling entry/exit of oil into/from a primary pulley oil chamber (41c) by using an electric oil pump (112) arranged in an oil path between the primary pulley oil chamber (41c) and the secondary pulley oil chamber (42c), wherein the discharge flow rate of the electric pump (112) is limited so as to be smaller than the discharge flow rate of the source pressure oil pump (100).
