Control device for continuously variable transmission
A control apparatus for a continuously variable transmission (1) that includes a belt-type continuously variable transmission mechanism (40) and friction engagement elements (32), (33) is disclosed. The control apparatus includes: an operation position detection section (65) configured to detect an operation position of a selection lever (50); a selection control section (60b) configured to execute a selection control for engaging the friction engagement elements (32), (33) from a time point at which a switching from a non-travel range to a travel range is detected; a determination section (60) configured to determine engagement states of the friction engagement elements (32, 33); and a pulley pressure control section (60c) configured to control a pulley pressure supplied to two pulleys (41), (42). A belt slippage during an engagement of clutches is suppressed while a load on an oil pump is reduced.
