Abstract
A method of controlling speed reduction the following ratio of a continuously variable speed transmission using change rate di/dt of speed reduction ratio as control value. EQU di/dt=-C.sub.1 *N/V.sup.2 *(dV.sub.o /dt)+C.sub.2 *1/V*(dN.sub.o /dt) +C.sub.3 *N/V.sup.2 *(dV.sub.o /dt-dV/Dt) or, EQU di/dt=-C.sub.4 *(N/V.sup.2)*dV.sub.o /dt*K.sub.cl +C.sub.5 *(1/V)*dN.sub.o /dt.
