EVALUATION FRICTION PARAMETER FOR STEPLESS TRANSMISSION
Describes the approach to the maximum friction between the belt and pulley into a continuously variable transmission. Such an assessment is necessary to accurately determine the maximum transmitted torque and track the status of the variator. Adaptive estimates are based on the Kalman filter, which estimates the parameters associated with the maximum friction. The filter does not require a priori knowledge of maximum values and does not require a detailed model of friction. This method can be used for both intact and damaged to belts.
