<p>The invention relates to a continuously variable transmission, in particular for a motor vehicle, provided with a control for the transmission ratio of the transmission, which control in a first operating mode controls the transmission ratio on the basis of one or more input signals and in a second operating mode controls the transmission ratio, for example on the basis of an external signal originating from the driver of the motor vehicle, along one or more control curves (C1-C5) of one or more sets of control curves, possibly within rotational speed limits (nmin,nmax) imposed on the input speed (neng) of the transmission. One or more control curves and/or one or more rotational speed limits are a function of the input speed of the transmission in such a way that, in accordance with said functions, the input speed of the transmission is not zero for a notional output speed of the transmission of zero. By this means the drive characteristics of the transmission are appreciably improved, coupled with improved efficiency and optimum power. <MATH></p> |
