Abstract
An operational parameter determination system is disclosed. The operational parameter determination system may include an operational parameter predictor configured to calculate an a priori estimated operational parameter of the machine based on a previously estimated operational parameter. The operational parameter determination system may also include a gear shifting compensator configured to determine whether a gear shifting is in progress, and when the gear shifting is in progress, to output the a priori estimated operational parameter as a determined operational parameter. The operational parameter determination system may further include an operational parameter updater configured to, when the gear shifting is not in progress, receive a measured operational parameter of the machine, determine an a posteriori estimated operational parameter of the machine based on the a priori estimated operational parameter and the measured operational parameter, and output the a posteriori estimated operational parameter as the determined operational parameter.
