ABSTRACT:
In order to achieve a gear ratio control of a continuously variable transmission, a transmission gear ratio is controlled based on a difference between an actual engine speed and a target engine speed to be set in response to a first parameter corresponding to an accelerator opening. When controlling the transmission gear ratio, a plurality of change characteristics of the transmission gear ratio are set for, in particular, the kickdown gear shifting. In response to a second parameter representing the driver's demand for a traveling condition, a change characteristic of the transmission gear ratio is selected from among the plurality of change characteristics of the transmission gear ratio, to execute the speed ratio control in accordance with the thus selected change characteristic of the transmission gear ratio when a kickdown gear shifting is needed.
