This paper focusses on the development of a component controllerfor a hydraulically actuated metal push-belt Continuously Variable Transmission(CVT), using models for the mechanical and the hydraulic part of the CVT. Theratio controller guarantees that one clamping pressure setpoint is minimal, whilethe other is raised above the minimum level to enable shifting. This approach is beneficial with respect to efficiency and wear. Vehicle experiments show that goodtracking is obtained. The largest deviations from the ratio setpoint are caused by hardware limitations.
