Patent ID: 7285072

Claim:
A control system for a vehicle, the vehicle including an engine, a continuously variable transmission for varying the transmission ratio between an output member of the engine and a ground engaging drive apparatus, and the vehicle including a power take-off shaft which is driveable by the engine at a fixed ratio of the engine speed, the control system including at least one control apparatus which is operative to provide inputs to a controller, the controller being responsive to inputs from the control apparatus when the control system is operating in a first operating mode, when the power take-off shaft is inoperative to provide output signals to the controller to vary the engine speed, and when the control system is operating in a second operating mode, when the power take-off shaft is operative and a desired engine speed and vehicle speed are set by an operator, responding to changes in load by providing output signals to vary the transmission ratio without changing the engine speed, and a mode selector control whereby an operator may select the first or second operating mode.
