Abstract:
A continuously variable transmission is provided having a driven element. The continuously variable transmission also has a first operator input device configured to transmit a first displacement signal corresponding to a displacement of the first operator input device. The continuously variable transmission further has a second operator input device configured to transmit a second displacement signal corresponding to a displacement of the second operator input device. In addition, the continuously variable transmission has a third operator input device configured to transmit a transmission operating mode request. Furthermore, the continuously variable transmission has at least one sensor configured to sense at least one parameter indicative of an operating condition of the transmission. Additionally, the continuously variable transmission has a controller configured to determine a driven element output request based on the operating request mode, the first displacement signal, the second displacement signal, and the at least one sensed parameter. The controller is also 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.
