ABSTRACT:
A continuously variable transmission (CVT) for use in a vehicle is controlled such that an actual engine speed Ne is equalized to a desired engine speed No. When a driver's request for a rapid speed change of the vehicle is addressed, a desired engine speed Ns for steady state or the desired engine speed No before the request is detected is defined as a first value Nc1. While the request continues the desired engine speed Ns for steady state which is determined by current values of vehicle running parameters is defined as a second value Nc2. The product B.multidot.(Nc2-Nc1) of a constant B and Nc2 minus Nc1 is calculated and defined as a desired engine speed during the request.
