Abstract
A continuously variable transmission on a motor vehicle is controlled by establishing a target terminal 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 G.sub.CAL is calculated on the basis of a marginal power Pa of the engine which drives the continuously variable transmission. A target present acceleration Gon required at the present time to vary the present acceleration up to the target terminal acceleration Go to be reached along a desired characteristic curve is established according to the difference .DELTA.G (=Go-G.sub.CAL) between the target terminal acceleration Go to be reached and the calculative acceleration G.sub.CAL. Then, the throttle valve of the engine on the motor vehicle and the continuously variable transmission are controlled so that the target terminal acceleration Gon will be reached.
