Patent ID: 8554427

Claim:
A control apparatus for a continuously variable transmission, the control apparatus being capable of selectively performing an automatic shift mode or a manual shift mode as a mode for a shift control, the apparatus comprising: an automatic shift control unit for calculating a target transmission gear ratio according to a driving condition of a vehicle when the automatic shift mode is currently being selected, and for causing a transmission gear ratio of the continuously variable transmission to match the target transmission gear ratio; a manual shift control unit for selecting one of multiple transmission gear stages, each one of the multiple transmission gear stages comprising a fixed transmission gear ratio, according to an operation input by a driver when the manual shift mode is currently being selected, and for causing the transmission gear ratio of the continuously variable transmission to match the fixed transmission gear ratio of the selected transmission gear stage; and a temporary target transmission gear ratio setting unit for setting a temporary target transmission gear ratio so that when a difference between a target transmission gear ratio calculated immediately after the mode is switched to the automatic shift mode, and the fixed transmission gear ratio of the transmission gear that has been selected in the manual shift mode immediately before the mode is switched to the automatic shift mode is greater than or equal to a set value, the temporary target transmission gear ratio falling between the target transmission gear ratio and the fixed transmission gear ratio, wherein if the temporary target transmission gear ratio is set, the automatic shift control unit causes the transmission gear ratio of the continuously variable transmission to match the target transmission gear ratio stepwise via the temporary target transmission gear ratio during a transition of the mode from the manual shift mode to the automatic shift mode.
