ABSTRACT:
A continuously variable transmission is controlled using a target acceleration map which contains values of target accelerations corresponding to a plurality of values of a first indication (e.g., the amount of depression of an accelerator pedal or the engine throttle opening) representative of the driver's intention for acceleration or deceleration and a plurality of values of a second indication representative of speeds of the motor vehicle. The target acceleration map is arranged such that when each of the values of the second indication is constant, each of the values of the target acceleration increases as the value of the first indication increases, at a rate which is greater if the first indication is smaller. From such a target acceleration map, a target acceleration is determined on the basis of the actual values of the values of the first and second indications at the time, and the speed reduction ratio of the transmission is controlled so that the target acceleration is achieved. In the target acceleration map, the cruising speed of the motor vehicle varies linearly as the values of the first indication vary.
