Document Type and Number:
WIPO Patent Application WO/2015/087900
Kind Code:
A1
Abstract:
Provided is a control device for a continuously variable transmission with an auxiliary gearbox, wherein the control device comprises: a primary solenoid valve (118) which is disposed in a position in an oil passage from a mechanical oil pump (10) to a primary pulley (21) and which controls oil pressure to the primary pulley (21); and a transmission controller (12) for outputting a primary current instruction value (PriSOL/I*) to the primary solenoid valve (118). When coasting-stop control or idle-stop control is being applied, and at least before the engine speed (Ne) rises due to engine restarting, the transmission controller (12) outputs to the primary solenoid valve (118) the primary current instruction value (PriSOL/I*) for preliminarily closing the oil passage from the mechanical oil pump (10) to the primary pulley (21).
