Patent attributes
A work machine gear shifting control device is capable of readily identifying the cause of failure in learning the clutch hydraulic pressure for operating a transmission clutch. A transmission gear shifting control section 46 is provided for each of clutches 61-65, and performs a learning process in which each of a plurality of handling processes learns the clutch hydraulic pressure for each of the clutches 61-65 and determines the clutch hydraulic pressure characteristic values for operating the individual clutches. Further, the transmission gear shifting control section 46 performs a learning monitoring process in each of the plurality of handling processes to formulate an error judgment, which indicates whether learning has failed in each of the plurality of subprocesses, and displays the result of the judgment.
