Abstract
A downstream rate limiting control is provided for controlling a continuously variable transmission. The rate limiting control monitors a input and a current machine state and computes the difference between these two inputs and compares the computed error to a predefined rate table to determine if the computed error should be limited or modified. The rate signal will modify the computed error within the control logic with respect to operator comfort and machine parameters.
