Method of controlling continuously variable transmission in combination with engine throttle control.

摘要

A continuously variable transmission on a motor vehicle is controlled by establishing a target acceleration Go to be reached according to an indication of the driver's intention for acceleration or deceleration, such as the amount of depression of the accelerator pedal, and also to an indication of the speed of the motor vehicle. A present calculative acceleration GCAL is calculated on the basis of a reserved power Pa of the engine which drives the continuously variable transmission. A target acceleration Gon required at the present time to vary the present acceleration up to the target acceleration Go to be reached along a desired characteristic curve is established according to the difference DELTA G (= Go - GCAL) between the target acceleration Go to be reached and the calculative acceleration GCAL. Then, the throttle valve of the engine on the motor vehicle and the continuously variable transmission are controlled so that the target acceleration Gon will be reached.
