Abstract
A continuously variable transmission can have one or more rotatable output shafts, rotatable non-output shafts, continuously variable transmission elements selectively interconnecting at least one non-output shaft and one output shaft so as to permit variation of a transmission ratio therebetween. The transmission can also have one or more control elements for controlling the instantaneously prevailing ratio of the transmission including a sensor device for sensing the rotational position of a non-output shaft, and a processing device for determining the rotational position of the sensed, non-output shaft at a chosen instant. The processing device is connected to control elements to cause variation of the transmission ratio so that the output shaft attains a desired rotational position at a chosen instant.
