METHOD OF CONTROLLING CONTINUOUSLY VARIABLE AUTOMOTIVE TRANSMISSION
The transmission ratio of an automotive continuously variable transmission is controlled on the basis of the difference between a target rotational speed of the engine which is preset according to an indication of the driver's intention of acceler-a-tion or deleration and a detected rotational speed of the engine. The gain of the rate of change of the transmission ratio is reduced as the detected rotational speed of the engine becomes higher, and the gain of the rate of change of the transmission ratio is increased as the detected rotational speed of the engine becomes lower. Alternatively, the gain of the rate of change of the transmission ratio is of a relatively small value when the detected rotational speed of the engine is equal to or higher than a preset speed, and the gain of the rate of change of the transmission ratio is of a relatively large value when the detected rotational speed of the engine is lower than said preset speed.
