Abstract:
A continuously variable transmission is provided having a driven element. The continuously variable transmission also has at least one operator input device configured to transmit a transmission operating mode request and at least one other operator input device configured to transmit a driven element output request. In addition, the continuously variable transmission has at least one sensor configured to sense at least one parameter indicative of an operating condition of the transmission. The continuously variable transmission further has a controller configured to regulate an output of the driven element in response to the operating mode request, the driven element output request, and the at least one sensed parameter indicative of an operating condition of the transmission.
