CONTROL DEVICE FOR CONTINUOUSLY VARIABLE TRANSMISSION EQUIPPED WITH AUXILIARY TRANSMISSION

摘要

A continuously variable transmission (4) mounted to a vehicle includes a variator (20) and a cooperative control means. In this control device with the auxiliary transmission, the cooperative control means (5) includes an inertia phase time period setting control section (S3, S7 of FIG. 5 ) configured to set a first inertia phase time period which is a cooperative shift inertia phase time period of an overall transmission, and a second inertia phase time period which is shorter than the first inertia phase time period. The cooperative control means ( FIG. 5 ) is configured to shift the auxiliary transmission mechanism during the first inertia phase time period, and to shift the variator during the second inertia phase time period, when the cooperative control in which an input torque to the continuously variable transmission is equal to or smaller than a predetermined value in the cooperative control is judged
