ABSTRACT:
In a controller which controls a speed change ratio of a continuously variable transmission to a target speed change ratio set based on the driving conditions of an automobile, the driver manually inputs a command which increases or decreases the speed change ratio. The controller increases or decreases the target speed change ratio by a predetermined amount according to this command. Preferably, this increase/decrease pattern is varied according to the time for which the command continues. The driver of the automobile can thereby achieve a desired speed change ratio by a simple operation.
