ABSTRACT:
A continuously variable transmission on a motor vehicle is controlled to control a speed reduction ratio using, as a control value, a rate of change di/dt of the speed reduction ratio that is determined using a reserve horsepower of an engine on the motor vehicle, an engine rotational speed Ne, a vehicle speed V of the motor vehicle, a present acceleration Ga of the motor vehicle, and a target acceleration Gon. A control process detects whether a rate of change of an indication by a driver of the motor vehicle of an intention to accelerate or decelerate the motor vehicle is greater than a predetermined value or not, whether a target engine rotational speed Neo corresponding to the indication is greater than an actual engine rotational speed Nea or not and whether the target acceleration Gon is greater than the present acceleration Ga on an acceleration side (positive side) or not. If the rate of change of the indication is greater than the predetermined value, the target engine rotational speed Neo is greater than the actual engine rotational speed Nea, and the target acceleration Gon is greater than the present acceleration Ga on the acceleration side (positive side), then an acceleration skip control process is determined as being required, and carried out to increase the rate of change di/dt of the speed reduction ratio immediately thereafter.
