Abstract

In a method of controlling a transmission ratio of a continuously variable toroidal transmission, a holding force for an intermediate roller is pilot-controlled as a function of the torques acting on the toroidal disks and of the pivoted position of the intermediate roller, and/or the adjustment path of the intermediate roller is fed back statically or dynamically into a control circuit.
