Method Of Controlling Gear Ratio Rate Of Change In Continuously Variable Transmission |
摘要 |
A method is provided for controlling a gear ratio rate of change in a machine having a continuously variable transmission. The method includes moving an operator input device to a changed position, receiving electronic data indicative of the changed position, and determining a non-limited desired gear ratio based at least in part on the changed position. A maximum gear ratio rate of change corresponding to the changed position is selected from an electronically stored gear ratio rate map. A current desired gear ratio is determined based at least in part on the non-limited desired gear ratio and the maximum gear ratio rate of change. The method also includes changing a commanded gear ratio of the continuously variable transmission to the current desired gear ratio using electronic signals.
