|Applicants:||NISSAN MOTOR CO., LTD.
|Title:||CONTROL METHOD AND CONTROL APPARATUS FOR CONTINUOUSLY VARIABLE TRANSMISSION|
This control method for a continuously variable transmission comprises: supplying oil pressure to a secondary pulley oil chamber by using a source pressure oil pump; and controlling entry/exit of oil into/from a primary pulley oil chamber by using an electric oil pump arranged in an oil path between the primary pulley oil chamber and the secondary pulley oil chamber, wherein after the source pressure oil pump starts, operation of the electric oil pump is restricted until oil fills the oil path closer to the secondary oil chamber rather than the electric oil pump.
